"MACROCYCLIC QUINAZOLINE DERIVATIVES AS ANTIPROLIFERATIVES AGENTS"

Abstract A macrocyclic quinazoline compound having the formula
Full Text The present invention relates to a macrocyclic quinazoline compound.
This invention relates to quinazoline derived macrocycles that have been found to possess anti-proliferative activity, such as anti-cancer activity and are accordingly useful in methods of treatment of the human or animal body, for example in the manufacture of medicaments for use in hyper proliferative disorders such as atherosclerosis, restenosis and cancer. The invention also relates to processes for the manufacture of said quinazoline derivatives, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of anti-proliferative effect.
In particular, the compounds of the present invention were found to inhibit tyrosine kinase enzymes, also called tyrosine kinases. Tyrosine kinases are a class of enzymes, which catalyse the transfer of the terminal phosphate of adenosine triphosphate to the phenolic hydroxyl group of a tyrosine residue present in the target protein. It is known, that several oncogenes; involved in the transformation of a cell into a malignant tumour cell, encode tyrosine kinase enzymes including certain growth factor receptors such as EGF, FGF, IGF-1R, IR, PDGF and VEGF. This family of receptor tyrosine kinases and in particular the EGF family of receptor tyrosine kinases are frequently present in common human cancers such as breast cancer, non-small cell lung cancers including adenocarcinomas and squamous cell cancer of the lung, bladder cancer, oesophageal cancer, gastrointestinal cancer such as colon, rectal or stomach cancer, cancer of the prostate, leukaemia and ovarian, bronchial or pancreatic cancer, which are examples of cell proliferation disorders.
Accordingly, it has been recognised that the selective inhibition of tyrosine kinases will be of value in the treatment of cell proliferation related disorders. Support for this view is provided by the development of Herceptin® (Trastuzumab) and Gleevec™ (imatinib mesylate) the first examples of target based cancer drugs. Herceptin® (Trastuzumab) is targeted against Her2/neu, a receptor tyrosine kinase found to be amplified up to 100-fold in about 30% of patients with invasive breast cancer. In clinical trials Herceptin® (Trastuzumab) proved to have anti-tumour activity against breast cancer (Review by L.K. Shawer et al, "Smart Drugs: Tyrosine kinase inhibitors in cancer therapy", 2002, Cancer Cell Vol.1,117), and accordingly provided the proof of principle for therapy targeted to receptor tyrosine kinases. The second example, Gleevec™ (imatinib mesylate), is targeted against the abelson tyrosine kinase (BcR-Abl), a constitutively active cytoplasmic tyrosine kinase present in virtually all patients with chronic myelogenous leukaemia (CML) and 15% to 30% of adult patients
-2- with acute lymphoblastic leukaemia. In clinical trials Gleevec™ (imatinib mesylate)
showed a spectacular efficacy with minimal side effects that led to an approval within
3 months of submission. The speed of passage of this agent through clinical trials and
regulatory review has become a case study in rapid drug development (Drucker B.J.
& Lydon N., "Lessons learned from the development of an Abl tyrosine kinase
inhibitor for chronic myelogenous leukaemia.", 2000, J.Clin.Invest. 105,3).
Further support is given by the demonstration that EOF receptor tyrosine
kinase inhibitors, specifically attenuates the growth in athymic nude mice of
transplanted carcinomas such as human mammary carcinoma or human squamous cell
carcinoma (Review by T.R. Burke Jr., Drugs of the Future, 1992,17,119). As a
consequence, there has been considerable interest in the development of drugs to treat
different cancers that target the EGFR receptor. For example, several antibodies that
bind to the extra-cellular domain of EGFR are undergoing clinical trials, including
Erbitux™ (also called C225, Cetuximab), which was developed by Imclone Systems
. and is in Phase IE clinical trials for the treatment of several cancers. Also, several
promising orally active drugs that are potent and relatively specific inhibitors of the
EGFR tyrosine kinase are now well advanced in clinical trials. The AstraZeneca
compound ZD1839, which is now called IRESSA® and approved for the treatment of
advanced non-small-cell lung cancer, and the OSI/Genentech/Roche compound OSI-
774, which is now called Tarceva™ (erlotinib), have shown marked efficacy against
several cancers in human clinical trials (Morin M.J., "From oncogene to drug:
development of small molecule tyrosine kinase inhibitors as anti-tumour and antiangiogenic
agents, 2000, Oncogene 19,6574).
In addition to the above, EOF receptor tyrosine kinases has been shown to be
implicated in non-malignant proliferative disorders such as psoriasis (Elder et al.,
Science, 1989, 243; 811). It is therefore expected that inhibitors of EGF type receptor
tyrosine kinases will be useful in the treatment of non-malignant diseases of excessive
cellular proliferation such as psoriasis, benign prostatic hypertrophy, atherosclerosis
and restenosis.
It is disclosed in International Patent Application WO96/33980 and in J. Med. Chem,
2002,45, 3865 that certain 4 anilino substituted quinazoline derivatives may be useful
as inhibitors of tyrosine kinase and in particular of the EGF type receptor tyrosine
kinases. Unexpectedly it was found that Quinazoline derivatives of the present
formula (I) that are different in structure, show to have tyrosine kinase inhibitory
activity.

It is accordingly an object of the present invention to provide further tyrosine kinase
inhibitors useful in the manufacture of medicaments in the treatment of cell
proliferative related disorders.

Using the aforementioned method in two alternative forms, 4-chloro-2-
nitrobenzaldehyde has been converted in suitable substituted anilines of formula
(HIb). In a first method (Scheme 5a) the suitable substituted anilines of formula (inb)
were obtained by reductive amination of 4-chloro-2-nitrobenzaldehyde with primary
amino acids.
A methanolic solution of 10 mmol aldehyde 1, 20 mmol amino acid 2,19 mmol KF, 1
mL 4% thiophene (inDIPE) and 1 g Pt/C (slurry in THF or MeOH) under 1 atm of
hydrogen is stirred at 50 °C (scheme 5a). The reaction mixture is filtered after
consumption of 4 equivalents of hydrogen (typically after 48 h) and 3 equivalents of
Boc anhydride are added. Next, the solution is stirred for 1-3 h at room temperature
(LCMS monitoring), then an excess of 6 N ammonia in MeOH is added, and stirring
is continued for 1 h to work-up excess Boc anhydride. Finally, the solution is
evaporated to dryness (sublimation of tert-butyl carbamate is observed) and the
resulting Boc-protected N-benzyl amino acid 4 is purified by HPLC. When R' is not
equal to hydrogen, Boc-protected aniline 5 is observed as the major product. In this
case method B can be employed to obtain the aniline of type 4 (vide infra).

A second method to obtain the suitable substituted anilines of formula (mb) has been
the reductive animation of primary and secondary amino acids, amino acid
hydrochlorides, N-methylallylamine and methylaminoacetaldehyde dimethyl acetal
with 4-chloro-2-nitrobenzaldehyde 1 and 4-chloro-3-fluoro-2-nitrobenzaldehyde 6
(Scheme 5b). Overall yields vary between 13 and 100%.
To a solution (suspension) of 5 mmol amine 7, 5 mmol aldehyde 1 or 6 in 30 mL
dichloromethane is added 5 mmol titanium(IV)tert-butoxide and 5 mmol DIPEA
(when 7 is hydrochloride).1 After stirring for 15 min, 12 mmol sodium
triacetoxyborohydride is added 'and stirring is continued for 1-5 h (LCMS
monitoring). Next, the reaction is worked up with 10-20 mL of a saturated NaHCOssolution
and stirring is continued until bubbling stops. The resulting emulsion is
filtered over a P3 sintered glass filter and washed with dichloromethane. The organic
layer is separated and the aqueous phase extracted with dichloromethane. Drying of
the combined organic layers with magnesium sulfate (or potassium carbonate),
followed by filtration and evaporation of the solvent yields the crude N-benzylamine
8, which is usually pure enough to use for the next reaction step.
When R is hydrogen, the secondary amine can be protected with a Boc or Cbz group
by respectively adding three equivalents of Boc anhydride or benzyl chloroformate
and three eq of DIPEA to a methylene chloride solution of the amine and stirring for

16-24 h at room temperature. When R' is bulky, Boc protection is generally slow and
requires prolonged refluxing in methylene chloride. Next, excess protecting agent is
worked up by adding 6 N ammonia in methanol and stirring for 1 h at room

The thus obtained benzylamine 8 is subsequently reduced either by hydrogenolysis or
in case R' contains a double bond by reduction with tin(n)chloride
Nitro reduction by hydrogenolysis
The benzylamine 8 is dissolved in methanol (or ethyl acetate or THF) and, upon
addition of 1 g Pt/C (slurry in EtOAc) and thiophene (1 mL 4% in DIPE), stirred
under 1 atm hydrogen at 50 °C (scheme 3, step a). After consumption of three
equivalents of hydrogen, the mixture is filtered over dicalite. Removal of the solvent
yields the crude aniline 9 which, depending on the nature and purity, can be
crystallized from heptane, purified by HPLC or used as a crude in the next reaction
step.
Nitro reduction with tin(II)chloride
This method was used when R' contains a double bond and hence cannot be reduced
hydrogenolytieally.

To an ethanolic solution of crude nitro compound 8 is added 5 eq of tin(II)chloride
dihydrate (scheme 3, step b). This mixture is stirred for 1.5 h at 50 °C. Next, the
solution is cooled to RT, and saturated sodium bicarbonate and methylene chloride
are added (bubbling). The resulting emulsion is filtered over a P3 sintered glass filter.
Separation of the organic layer, followed by drying on anhydrous potassium
carbonate, filtering and removal of the solvent yields the crade aniline 9, which is
usually pure enough to be used in the next reaction step.
For those compounds where X2 represents -O-N=CH-, the suitable substituted
anilines of formula (IE0) are generally prepared according to reaction scheme 6.
In a first step the known 2-nitro-benzaldehydes (Xni) are converted into the
corresponding oxime (XVII) using, for example, the art known condensation reaction
with hydroxylamine.
Next said oxime of formula XVII is allowed to react with an halogenated alkylacetate
under alkaline conditions, for example using KaCOs in DMSO, followed by reducing
the nitro group, for example, with hydrogenolysis (Ha, Pt/C, thiophene, MeOH) or
tin(n)chloride (SnCk-HaO, EtOH), to provide the suitable substituted aniline of

As shown in scheme 9b, the ester function is then hydrolyzed, and Boc group(s)
removed, by stirring a dioxane solution of 13 overnight at 60 °C in the presence of 6
N HCI (R = Me, Et) or at RT in the presence of TFA/CH2C12/TIS (90:8:2) (R = tBu).
After evaporation to dryness, the resulting amino acid 14 is redissolved in dry DMF
and, upon addition of 6 eq of DIPEA, added dropwise to a solution of 3 eq HBTU (or
-41-
PyBOP)2 in dry DMF. Stirring this solution for 1 h at RT, followed by evaporation of
the solvent yields the crude macrocycle 15a, which is purified by RP HPLC. A prepurification
can be done by dissolving the residue in CHaCk and washing it with
saturated sodium bicarbonate in water, followed by drying on potassium carbonate
and removal of the solvent. The yield for this sequence is 10-65% starting from the
aniline 4 or 9.
A Cbz group, if present, can be removed prior purification by dissolving the crude
macrocycle 15a (R"" = Cbz) in 48 % aqueous HBr and stirring for 1-2 h at room
temperature (RT). After concentration of the reaction mixture and quenching with
solid potassium carbonate, the deprotected macrocycle 15b is obtained by extraction
with CBbCk (with added methanol in case of solubility problems), and is similarly
purified by RP HPLC. The yield for Cbz deprotection is quantitative by LCMS.
To a solution of N-benzyl amino acid 4 or 9 in isopropanol is added one equivalent of
chloroquinazoline 10 (scheme lOa). The resulting solution is stirred for 2-24 h at 80
°C to give 11. Next, the mixture is cooled to RT and a 6 N methanolic solution of
ammonia is added. After stirring for one hour, the solution is evaporated to dryness.
The crude phenol 12 is then redissolved in dry DMF and, upon addition of 5
equivalents of cesium carbonate, stirred for one hour at RT. To the resulting phenolate
is then added 0.8 eq (to prevent overalkylation) of 4-bromobutyronitrile, and the
mixture is stirred overnight at RT, evaporated to dryness, redissolved in
dichloromethane and filtered over dicalite to remove cesium salts.
2 PyBop generates tris(pyrrolidino)phosphinoxide, which is often difficult to separate from the
macrocycle. HBTU generates tetramethylurea, which is more easy to remove.

Crude 16 is then thoroughly dried, redissolved in 6 N ammonia/MeOH (to prevent

dechlorination), treated with wet Raney nickel under 1 atm hydrogen pressure at 14
°C (scheme lOb). After consumption of 2 equivalents of hydrogen gas (typically after
16-24 h), the mixture is filtered over dicalite and concentrated to provide the crude
amine 17. The ester function is then hydrolyzed to 18 (and, if R'" = Boc, the Boc
group removed) by stirring a dioxane solution of 17 overnight in the presence of 6 N
HC1 (R = Me, Et). After evaporation to dryness, the resulting amino acid 18 is
redissolved in dry DMF and, upon addition of 6 eq of DIPEA, added dropwise to a
solution of 3 eq HBTU (or PyBOP) in dry DMF. Stirring this solution for 1 h at RT,
followed by evaporation of the solvent yields the crude macrocycle 19, which is
purified by RP HPLC. A pre-purification can be done by dissolving the residue in
CHzCk and washing it with saturated sodium bicarbonate in water. The yield for this

To a solution of 5-chloro-2-{[(2,2-dimethoxyethyl)(methyl)amino]methyl} aniline 20
or the corresponding dioxolane (prepared via reductive amination Scheme 5b) in
isopropanol is added one equivalent of chloroquinazoline 10. The resulting solution is
stirred for 7-8 h at 80 °C to give 21. Next, the mixture is cooled to RT and a 6 N
methanolic solution of ammonia is added to remove the acetyl group. After stirring
for one hour, the solution is evaporated to dryness. To the crude phenol 22 is then
added 5 eq of cesium carbonate and, after stirring for 1 h, Boc-aminoalkyl bromide
(1.0-1.2 eq) or 5-bromobutyronitrile (0.8 eq), and the mixture is subsequently stirred
overnight at RT evaporated to dryness, redissolved in dichloromethane and filtered
-45-
over dicalite to remove cesium salts. This yields the protected aminoalkyl-substituted
phenols 23. The butyronitrile-substituted phenol is first hydrogenated to the
corresponding amine under the abovementioned conditions.
Next the compounds are dissolved in 6 N HC1 and dioxane, and the resulting mixture
is stirred for about 24 h at 60 °C (LCMS monitoring, formation of imine 24 is
observed) (scheme 11). After completion of the reaction, the mixture is poured
carefully into an ice-cooled sodium bicarbonate solution or evaporated to dryness
(slow, leads to decomposition). In the first case, the imine is extracted with methylene
chloride and, after drying on potassium carbonate, immediately reduced to the
corresponding amine by addition of sodium triacetoxyborohydride. In the latter case,
the oily residue is redissolved in methylene chloride and excess sodium
triacetoxyborohydride is added to yield the corresponding amine. The crude
macrocycle 25 is obtained after addition of saturated sodium carbonate, extraction
with dichloromethane followed by drying on potassium carbonate and removal of the
solvent, and can be purified RP HPLC.

In this procedure the aniline 26 is coupled with the appropriate amino protected amino
acid, to form the amide of formula 27 using art known conditions, see for example
A42 d) hereinbelow. Subsequent coupling with the chloroquinazoline under standard
conditions, for example stirred in propanol at an elevated temperature ranging form
40-100°C during 3-12 h, provides the intermediates of formula 28. Alkylation with
the appropriate haloacetate followed by deprotection and ring closure, i.e. amide
formation using art known conditions, provides the compounds of formula 30.
Deprotection of the intermediates of formula 28 can be done as described in
Protective Groups in Organic Synthesis by T.W. Greene andP.G.M. Wuts, 3rd edition,
1998.
Alternatively, the compounds of formula (I) are prepared by ring closing metathesis
of the corresponding olefins (Scheme 13). This reaction is particular useful for those

substituted with amino, mono-or di(Ci^alkyl)amino or Ci-4alkyloxycarbonylaminohereinafter
referred to as the compounds of formula (Fc).
In a first step the aniline of formula (me) is coupled to the 4-chloroquinazoline (IIb)
under standard conditions, for example stirred in propanol at an elevated temperature
ranging from 40-100°C during 3-12 h. Deprotection of the intermediate of formula
(IV0) as described in Protective Groups in Organic Synthesis by T. W. Greene and
P.G.M. Wuts, 3rd edition, 1998, followed by alkylation with the appropriate alkyl
bromides (XXXII) under art known conditions, such as for example stirring overnight
at room temperature in the presence of Cs2CO3 in a reaction inert solvent such as for
example N,N-dimethylformamide (DMF), provides the olefins of formula (XXXHI).
Ring closing metathesis as described in Advanced Organic Chemistry by J. March, 3'
edition, 1985, p!036-1039 provides the compounds of formula (Fc) that can
optionally be reduced using art known procedures, for example, stirring for 3-10 h at
room temperature under H2-atmosphere in the presence of Pt/C in tetrahydrofuran

Where necessary or desired, any one or more of the following further steps in any
order may be performed :
(i) removing any remaining protecting group(s);
(ii) converting a compound of formula (I) or a protected form thereof into a further
compound of formula (I) or a protected form thereof;
(iii) converting a compound of formula (I) or a protected form thereof into a //-oxide,
a salt, a quaternary amine or a solvate of a compound of formula (I) or a protected
form thereof;
-48-
(iv) converting a Af-oxide, a salt, a quaternary arnine or a solvate of a compound of
formula (I) or a protected form thereof into a compound of formula (I) or a
protected form thereof;
(v) converting a //-oxide, a salt, a quaternary arnine or a solvate of a compound of
formula (I) or a protected form thereof into another A/-oxide, a pharmaceutically
acceptable addition salt a quaternary arnine or a solvate of a compound of formula
(I) or a protected form thereof;
(vi) where the compound of formula (I) is obtained as a mixture of (R) and (S)
enantiomers resolving the mixture to obtain the desired enantiomer.
Compounds of formula (I), Af-oxides, addition salts, quaternary amines and
stereochemical isomeric forms thereof can be converted into further compounds
according to the invention using procedures known in the art.
It, will be appreciated by those skilled in the ait that in the processes described above
the functional groups of intermediate compounds may need to be blocked by
protecting groups.
Functional groups, which it is desirable to protect, include hydroxy, amino and
carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl groups
(e.g. tert-butyldimethylsilyl, tert-butyldiphenylsilyl or trimethylsilyl), benzyl and
tetrahydropyranyl. Suitable protecting groups for amino include tertbutyloxycarbonyl
or benzyloxycarbonyl. Suitable protecting groups for carboxylic
acid include C(i-6)alkyl or benzyl esters.
The protection and deprotection of functional groups may take place before or after a
reaction step.
Additionally, the N-atoms in compounds of formula (I) can be methylated by artknown
methods using CH3-I in a suitable solvent such as, for example 2-propanone,
tetrahydrofuran or dimethylformamide.
The compounds of formula (I) can also be converted into each other following artknown
procedures of functional group transformation of which some examples are
mentioned hereinafter.
-49-
The compounds of formula (I) may also be converted to the corresponding //-oxide
forms following art-known procedures for converting a trivalent nitrogen into its
//-oxide form. Said //-oxidation reaction may generally be carried out by reacting the
starting material of formula (I) with 3-phenyl-2-(phenylsulfonyl)oxaziridine or with
an appropriate organic or inorganic peroxide. Appropriate inorganic peroxides
comprise, for example, hydrogen peroxide, alkali metal or earth alkaline metal
peroxides, e.g. sodium peroxide, potassium peroxide; appropriate organic peroxides
may comprise peroxy acids such as, for example, benzenecarboperoxoic acid or halo
substituted benzenecarboperoxoic acid, e.g. 3-chlorobenzenecarboperoxoic acid,
peroxoalkanoic acids, e.g. peroxoacetic acid, alkylhydroperoxides, e.g. t-butyl
hydroperoxide. Suitable solvents are, for example, water, lower alkanols, e.g. ethanol
and the like, hydrocarbons, e.g. toluene, ketones, e.g. 2-butanone, halogenated
hydrocarbons, e.g. dichloromethane, and mixtures of such solvents.
Pure stereochemically isomeric forms of the compounds of formula (I) may be
obtained by the application of art-known procedures. Diastereomers may be
separated by physical methods such as selective crystallization and chrornatographic
techniques, e.g. counter-current distribution, liquid chromatography and the like.
Some of the compounds of formula (I) and some of the intermediates in the present
invention may contain an asymmetric carbon atom. Pure stereochemically isomeric
forms of said compounds and said intermediates can be obtained by the application of
art-known procedures. For example, diastereoisomers can be separated by physical
methods such as selective crystallization or chrornatographic techniques, e.g. counter
current distribution, liquid chromatography and the like methods. Enantiomers can be
obtained from racemic mixtures by first converting said racemic mixtures with
suitable resolving agents such as, for example, chiral acids, to mixtures of
diastereomeric salts or compounds; then physically separating said mixtures of
diastereomeric salts or compounds by, for example, selective crystallization or
chrornatographic techniques, e.g. liquid chromatography and the like methods; and
finally converting said separated diastereomeric salts or compounds into the
corresponding enantiomers. Pure stereochemically isomeric forms may also be
obtained from the pure stereochemically isomeric forms of the appropriate
intermediates and starting materials, provided that the intervening reactions occur
stereospecifically.
-50-
An alternative manner of separating the enantiomeric forms of the compounds of
formula (I) and intermediates involves liquid chromatography, in particular liquid
chromatography using a chiral stationary phase.
Some of the intermediates and starting materials as used in the reaction procedures
mentioned hereinabove are known compounds and may be commercially available or
may be prepared according to art-known procedures. However, in the synthesis of the

cancer, the method comprising administering to an animal in need of such treatment,
for example, a mammal including humans, suffering from a cell proliferative disorder,
a therapeutically effective amount of a compound according to the present invention.
-66-
Said method comprising the systemic or topical administration of an effective amount
of a compound according to the invention, to animals, including humans. One skilled
in the art will recognize that a therapeutically effective amount of the EGFR
inhibitors of the present invention is the amount sufficient to induce the growth
inhibitory effect and that this amount varies inter alia, depending on the size, the type
of the neoplasia, the concentration of the compound in the therapeutic formulation,
and the condition of the patient. Generally, an amount of EGFR inhibitor to be
administered as a therapeutic agent for treating cell proliferative disorder such as
atherosclerosis, restenosis and cancer, will be determined on a case by case by an
attending physician.
Generally, a suitable dose is one that results in a concentration of the EGFR inhibitor
at the treatment site in the range of 0.5 nM to 200 uM, and more usually 5 nM to 10
uM. To obtain these treatment concentrations, a patient in need of treatment likely
will be administered between 0.01 mg/kg to 300 mg/kg body weight, in particular
from 10.mg/kg to 100 mg/kg body weight. As noted above, the above amounts may
vary on a case-by-case basis. In these methods of treatment the compounds according
to the invention are preferably formulated prior to admission. As described herein
below/suitable pharmaceutical formulations are prepared by known procedures using
well known and readily available ingredients.
Due to their high degree of selectivity as EGFR inhibitors, the compounds of
formula (I) as defined above, are also useful to mark or identify the kinase domain
within the receptor tyrosine kinase receptors. To this purpose, the compounds of the
present invention can be labelled, in particular by replacing, partially or completely,
one or more atoms in the molecule by their radioactive isotopes. Examples of
interesting labelled compounds are those compounds having at least one halo which is
a radioactive isotope of iodine, bromine or fluorine; or those compounds having at
least one * ^C-atom or tritium atom.
One particular group consists of those compounds of formula (I) wherein R* is a
radioactive halogen atom. In principle, any compound of formula (I) containing a
halogen atom is prone for radiolabelling by replacing the halogen atom by a suitable
isotope. Suitable halogen radioisotopes to this purpose are radioactive iodides, e.g.
1221,123I,1251,131I; radioactive bromides, e.g. 75Br, 76Br, 77Br and 82Br, and radioactive
fluorides, e.g. 18F. The introduction of a radioactive halogen atom can be performed
by a suitable exchange reaction or by using any one of the procedures as described
-67-
hereinabove to prepare halogen derivatives of formula (I).
Another interesting form of radiolabelling is by substituting a carbon atom by a
1 'C-atom or the substitution of a hydrogen atom by a tritium atom.
Hence, said radiolabelled compounds of formula (I) can be used in a process of
specifically marking receptor sites in biological material. Said process comprises the
steps of (a) radiolabelling a compound of formula (I), (b) administering this radiolabelled
compound to biological material and subsequently (c) detecting the emissions
from the radiolabelled compound.
The term biological material is meant to comprise every kind of material which
has a biological origin. More in particular this term refers to tissue samples, plasma
or body fluids but also to animals, specially warm-blooded animals, or parts of
animals such as organs.
When used in in vivo assays, the radiolabelled compounds are administered in an
appropriate composition to an animal and the location of said radiolabelled
compounds is detected using imaging techniques, such as, for instance, Single Photon
Emission Computerized Tomography (SPECT) or Positron Emission Tomography
(PET) and the like. In this manner the distribution of the particular receptor sites
throughout the body can be detected and organs containing said receptor sites can be
visualized by the imaging techniques mentioned hereinabove. This process of imaging,
an organ by administering a radiolabelied compound of formula (I) and detecting the
emissions from the radioactive compound also constitutes a part of the present
invention.
In yet a further aspect, the present invention provides the use of the compounds
according to the invention in the manufacture of a medicament for treating any of the
aforementioned cell proliferative disorders or indications.
The amount of a compound according to the present invention, also referred to here as
the active ingredient, which is required to achieve a therapeutical effect will be, of
course, vary with the particular compound, the route of administration, the age and
condition of the recipient, and the particular disorder or disease being treated. A
suitable daily dose would be from 0.01 mg/kg to 300 mg/kg body weight, in particular
from 10 mg/kg to 100 mg/kg body weight. A method of treatment may also include
administering the active ingredient on a regimen of between one and four intakes per
day.
While it is possible for the active ingredient to be administered alone, it is preferable
-68-
to present it as a pharmaceutical composition. Accordingly, the present invention
further provides a pharmaceutical composition comprising a compound according to
the present invention, together with a pharmaceutically acceptable carrier or diluent.
The carrier or diluent must be "acceptable" in the sense of being compatible with the
other ingredients of the composition and not deleterious to the recipients thereof.
The pharmaceutical compositions of this invention may be prepared by any methods
well known in the art of pharmacy, for example, using methods such as those
described in Gennaro et al. Remington's Pharmaceutical Sciences (18th ed., Mack
Publishing Company, 1990, see especially Part 8 : Pharmaceutical preparations and
their Manufacture). A therapeutically effective amount of the particular compound, in
base form or addition salt form, as the active ingredient is combined in intimate
admixture with a pharmaceutically acceptable carrier, which may take a wide variety
of forms depending on the form of preparation desired for administration. These
pharmaceutical compositions are desirably in unitary dosage form suitable, preferably,
for systemic administration such as oral, percutaneous or parenteral administration; or
' topical administration such as via inhalation, a nose spray, eye drops or via a cream,
gel, shampoo or the like. For example, in preparing the compositions in oral dosage
. form, any of the usual pharmaceutical media may be employed, such as, for example,
water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as
suspensions, syrups, elixirs and solutions: or solid carriers such as starches, sugars,
kaolin, lubricants, binders, disintegrating agents and the like in the case of powders,
pills, capsules and tablets. Because of their ease in administration, tablets and capsules
represent the most advantageous oral dosage unit form, in which case solid pharmaceutical
carriers are obviously employed. For parenteral compositions, the carrier will
usually comprise sterile water, at least in large part, though other ingredients, for
example, to aid solubility, may be included. Injectable solutions, for example, may be
prepared in which the carrier comprises saline solution, glucose solution or a mixture
of saline and glucose solution. Injectable suspensions may also be prepared in which
case appropriate liquid carriers, suspending agents and the like may be employed. In
the compositions suitable for percutaneous administration, the carrier optionally
comprises a penetration enhancing agent and/or a suitable wettable agent, optionally
combined with suitable additives of any nature in minor proportions, which additives
do not cause any significant deleterious effects on the skin. Said additives may
facilitate the administration to the skin and/or may be helpful for preparing the desired
compositions. These compositions may be administered in various ways, e.g., as a
transdermal patch, as a spot-on or as an ointment.
-69-
It is especially advantageous to formulate the aforementioned pharmaceutical
compositions in dosage unit form for ease of administration and uniformity of dosage.
Dosage unit form as used in the specification and claims herein refers to physically
discrete units suitable as unitary dosages, each unit containing a predetermined
quantity of active ingredient calculated to produce the desired therapeutic effect in
association with the required pharmaceutical carrier. Examples of such dosage unit
forms are tablets (including scored or coated tablets), capsules, pills, powder packets,
wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like,
and segregated multiples thereof.

Compound identification
-152-
The compounds were identified by LC/MS using a gradient elution system on a
reversed phase HPLC. The compounds are identified by their specific retention time
and their protonated molecular ion MH+ peak. The HPLC gradient was supplied by a
Waters Alliance HT 2790 system with a.columnheater set at 40°C. Flow from the
column was split to a Waters 996 photodiode array (PDA) detector and a Waters-
Micromass ZQ mass spectrometer with an electrospray ionization source operated in
positive and negative ionization mode. Reversed phase HPLC was carried out on a
Xterra MS CIS column (3.5 |um, 4.6 x 100 mm) with a flow rate of 1.6 ml/min. Three
mobile phases (mobile phase A 95% 25mM ammoniumacetate + 5% acetonitrile;
mobile phase B: acetonitrile; mobile phase C: rnethanol) were employed to run a
gradient condition from 100 % A to 50% B and 50% C in 6.5 minutes, to 100 % B in
1 minute, 100% B for 1 minute and reequilibrate with 100 % A for 1.5 minutes. An
injection volume of 10 uL was used.
Mass spectra were acquired by scanning from 100 to 1000 in Is using a dwell time of
0.1 s. The capillary needle voltage was 3kV and the source temperature was
maintained at 140°C . Nitrogen was used a the nebulizer gas. Cone voltage was 10 V
for positive ipnzation mode and 20 V for negative ionizatjon mode. Data acquisition
was performed with a Waters-Micromass MassLynx-Openlynx data system.

C. Pharmacological examples
Example C.I : in vitro inhibition of EGFR using a Scintillant Proximity Assay
In the present EGFR SPA kinase reaction assay, a kinase substrate consisting of
biotinylated poly(L-glutamic acid-L-tyrosine) (poly(GT)biotin), is incubated with the
aforementioned protein in the presence of (33P) radiolabeled ATP. (33P) phosporylation
of the substrate is subsequently measured as light energy emitted using streptavidincoated
SPA beads (Amersham Pharmacia Biotech) by trapping arid quantifying the
binding of the biotin tagged and radiolabeled substrate.
Detailed description
The EGFR SPA kinase reaction is performed at 30°C for 60 minutes in a 96-well
rnicrotiter plate. For each of the tested compounds a full dose response 1.10"6Mto 1.10"
10M has been performed. IRESSA® and Tarceva™ (erlotinib) were used as reference
compounds. The 100 p,} reaction volume contains 54.5 rnM TrisHCl pH 8.0, 10 mM
MgCI2, lOOuM Na3VO4, 5.0 /zM unlabeled ATP, ImM DTT, 0.009% BSA, 0.8 |LiCi
33P-ATP, 0.35 /ig/well poly(GT)biotin and 0.5 jug EGFR-kinase domain/well.
The reaction is stopped by adding to each well 100 u.1 of the streptavidin beads (10
mg/ml in PBS + 100 mM EDTA + 100 (iM ATP). The plates are than shaked at 300
rpm for 30 min to allow binding of the biotinylated substrate to the streptavidin coated
beads. Than the beads are allowed to settle at the bottom of the plate for 30 minutes.
The microtiterplates are centrifuges at 800 rpm for 10 minutes and the amount of
phosphorylated (33P) Poly(GT)biotin is determined by counting (30sec/well) in a
microtiterplate scintillation counter.
Example C.2 : in vitro inhibition of EGFR
The in vitro inhibition of EGFR was assessed using either the Flash Plate technology or
the glass-fiber filter technology as described by Davies, S.P. et al., Biochem J. (2000),
351; p.95-105. The Flash Plate technology is generally described by B.A. Brown et al.
in High Throughput Screening (1997), p.317-328. Editor(s): Devlin, John P.
Publisher: Delcker, New York, N. Y.
In the Flash Plate EGFR kinase reaction assay, a kinase substrate consisting of
biotinylated poly(L-glutamic acid-L-tyrosine) (poly(GT)biotin), is incubated with the
aforementioned protein in the presence of (33P) radiolabeled ATP. (33P) phosporylation
-155-
of the substrate is subsequently measured as light energy emitted using a streptavidincoated
Flash Plate (PerkinElmer Life Sciences) by trapping and quantifying the binding
of the biotin tagged and radiolabeled substrate.
Detailed description
The EGFR kinase reaction is performed at 30°C for 60 minutes in a 96-well microtiter
FlashPlate (PerkinElmer Life Sciences). For each of the tested compounds a full dose
response 1.10~6M to 1.10"10M has been performed. IRESSA® andTarceva™ (erlotinib)
were used as reference compounds. The 100 /il reaction volume contains 54.5 mM
TrisHCI pH 8.0, 10 mM MgCl2, lOOuM Na3VO4,5.0 /iM unlabeled ATP, ImM DTT,
0.009% BSA, 0.8 uCi AT33P, 0.35 /ig/well poly(GT)biotin and 0.5 /ig EGFR-kinase
domain/well.
The reaction is stopped by aspirating the reaction mixture and washing the plate 3x
. with 200 ul wash/stop buffer (PBS + 100 mM EDTA). After the final wash step 200 (.il
of wash/stop buffer was added to each well and the amount of phosphorylated (33P)
} Poly(GT)biotin determined by counting (30 sec/well) in a microtiferplate scintillation
counter.
In the glass-fiber filter technology EGFR kinase reaction assay, a kinase substrate
consisting of poly(L-glutamic acid-L-tyrosine) (poly(GT)), is incubated with the
aforementioned protein in the presence of (33P) radiolabeled ATP. (33P) Phosporylation
of the substrate is subsequently measured as radioactivity bound on a glassfiber-filter.
Detailed description
The EGFR kinase reaction is performed at 25°C for 10 minutes in a 96-well
microtiterplate. For each of the tested compounds a full dose response 1.10"6M to 1.10"
10M has been performed. IRESSA® and Tarceva™ (erlotinib) were used as reference
compounds. The 25 jul reaction volume contains 60 mM TrisHCI pH 7.5, 3 mM .
MgCl2, 3 mM Mn C12, 3 fiM Na3VO4,50 ng/ml PEG20000, 5.0 /iM unlabeled ATP,
ImM DTT, 0.1 uCi AT33P, 62.5 ng/well poly(GT) and 0.5 /ig EGFR-kinase
domain/well.
The reaction is stopped by adding 5 /il of a 3% phosphoric acid solution. 10 /d of the
reaction mixture is then spotted onto a Filtermat A filter (Wallac) and washed 3 times
for 5 min. in 75 mM phosphoric acid and 1 time for 5 min. in methanol prior to drying
and quantification on the Typhoon (Amersham) using a LE phosphorage storage
screen.

Example C.3: Serum starved proliferation assay on the ovarian carcinoma SKOV3 cells
The ovarian carcinoma cell line (SKOV3) was used in an epidermal growth factor
stimulated cell proliferation assay, to assess the inhibitory effect of the compounds on
EGF in whole cells.
In a first step the SKOV3 cells were incubated for 24 hours in the presence of 10% PCS
serum. In the second step the cells were incubated with the compounds to be tested in a
serum free condition (37 °C and 5% (v/v) CO2) and subsequently stimulated for 72
hours with EGF at a final concentration of 100 ng/ml. The effect of the compounds on
the EGF stimulation was finally assessed in a standard MTT cell viability assay.
Alternatively, the SKOV3 cells were incubated for 24 hours in the presence of 10%
FCS serum. In the second step the cells were incubated for 72 hours with the
compounds to be tested and the effect of the compounds on cell proliferation was
finally assessed in a standard MTT cell viability assay.
Example C.4: ELISA assay of EGFR tyrosine kinase activity
The EGFR ELISA is generally described by Yang, E.B. et al, 2001, Biochimica et
Biophysica Acta, 1550; 144.
For the determination of EGFR tyrosine kinase activity, 100 f*I of 0.4 jig/ml poly(Glu,
Tyr) in PBS was coated per well on a 96-well microplate at 37°C overnight. The nonspecific
binding sites were subsequently blocked by incubation for 30 minutes at room
temperature with 200 jjil BSA dilution (10 rag/ml in PBS) per well. After washing
three times with PBS the plates were either used immediately or stored at 4°C.
Prior to the determination of the EGFR tyrosine kinase activity, the coated plates were
washed two times with PBS. Next, to each well 88 \il of an ATP dilution (50 mM Tris
HC1 pH 8.0,10 mM MgCl2,100 \M Na3VO4) 1 mM DTT, 5 jiM ATP) and 2 |il with
various concentrations of the compounds to be tested, were added. The EGFR tyrosine
kinase-catalysed reaction was started by the addition of 10 ul of diluted EGFR (dilution
-> 0.05 Mg per well enzyme diluted in 50 mM TrisHCl pH 8.0 + 0,1% BSA).
After incubation at room temperature for 10 min, the reaction was stopped by washing
five times with PBS with 0.1% Tween 20. Subsequently 100 ml of recombinant antiphosphotyrosine
horseradish peroxidase conjugate (1:2500) in BSA (lOmg/ml in PBS)
was added. After incubation at room temperature for 1 h, the microplate was washed
five times with PBS/Tween 20. After the microplate was incubated with 100 pi of
-157-
TMB-ELIS A (1-step Ultra TMB-ELISA, Pierce) until colour development, 100 fil of
0.5 M H2SO4 was added to stop the reaction, and it was read in a microplate reader at
450-655 nm.
Example C.5: Proliferation assay on the squamous carcinoma cell line A431 cells
The squamous carcinoma cell line (A431) was used in a cell proliferation assay, to
assess the inhibitory effect of the compounds in whole cells.
In a first step the A431 cells were incubated for 24 hours in the presence of 10% PCS
serum. In the second step the cells were incubated for 72 hours with the compounds to
be tested at a final concentration of 100 ng/ml. The effect of the compounds on the cell
proliferation was finally assessed in a standard MTT cell viability assay.

D. Composition examples
The following formulations exemplify typical pharmaceutical compositions suitable for
systemic administration to animal and human subjects in accordance with the present
invention.
"Active ingredient" (A.I.) as used throughout these examples relates to a compound of
formula (I) or a pharmaceutically acceptable addition salt thereof.
Examle D.I : film-coated tablets
A mixture of A.I. (100 g), lactose (570 g) and starch (200 g) was mixed well and
thereafter humidified with a solution of sodium dodecyl sulfate (5 g) and polyvinylpyixolidone
(10 g) in about 200 ml of water. The wet powder mixture was sieved, dried
and sieved again. Then there was added microcrystalline cellulose (100 g) and
hydrogenated vegetable oil (15 g). The whole was mixed well and compressed into
tablets, giving 10.000 tablets, each comprising 10 mg of the active ingredient.
.Coating
To a solution of methyl cellulose (10 g) in denaturated ethanol (75 ml) there was added a
solution of ethyl cellulose (5 g) in DCM (150 ml). Then there were added DCM (75 ml)
-166-
and 1,2,3-propanetriol (2.5 ml). Polyethylene glycol (10 g) was molten and dissolved in
dichloromethane (75 ml). The latter solution was added to the former and then there were
added magnesium octadecanoate (2.5 g), poly vinyl-pyrrolidone (5 g) and concentrated
color suspension (30 ml) and the whole was homogenated. The tablet cores were coated
with the thus obtained mixture in a coating apparatus.
