Patent Document 4 discloses compounds, for example, shown below, which
are demonstrated to be valuable as antihypertensives.

However, none of the above-mentioned Patent Documents 1 to 4 mentions
activity for bone metabolic diseases and inflammation, and therefore the purposes of
the uses of such compounds are quite different from those of the present invention.

4
Furthermore, only the structures have been known for the compounds shown below.
and the uses thereof are not known at all.

In general, in normal bone metabolism, bone resorption by osteoclasts is
balanced with bone formation by osteoblasts to maintain homeostasis. It is thought
that bone metabolic diseases are caused when the balance between the bone
resorption and the bone formation is deteriorated. Bones retain about 99% of the
total calcium in a living body and play an important role for maintaining a constant
blood calcium concentration by bone formation and bone resorption. If the
osteoclasts which are mainly responsible for bone resorption are abnormally formed
or activated, bone resorption is accelerated to increase the blood calcium
concentration, and thereby bone metabolic diseases, such as hypercalcemia, are
caused.

5
It is known that bone metastasis of cancer causes abnormal secretion of
cytokines resulting in development of hypercalcemia. In this process, bone
resorption by osteoclasts is accelerated, so that the blood calcium concentration is
increased (Non-Patent Document 1). Prognosis of cancer patients accompanied by
cancerous hypercalcemia is generally poor.
Moreover, in rheumatoid arthritis, osteoarthritis and the like, abnormal
formation or activation of osteoclasts is known as one of main causes of various
symptoms in bones and joints (Non-Patent Document 2). Patients with rheumatoid
arthritis, osteoarthritis, and the like suffer from severe pain, which brings
considerable disadvantages to the lives of the patients.
Furthermore, when the balance between bone resorption and bone formation
continuously inclines toward the bone resorption due to a decrease in secretion of
female hormones after menopause or due to ageing, bone density is lowered and
osteoporosis is developed. Also in this case, osteoclasts are also responsible for the
bone resorption.
When aged patients with a high risk of osteoporosis suffer fractures, a
possibility of becoming bedridden is high, which is a social problem (Non-Patent
Document 3).
Conventionally, for these states of diseases, hormone replacement therapy
using estrogen or the like has been conducted or a therapeutic agent such as a
bisphosphonate or a calcitonin for suppressing the activity of osteoclasts has been
administered (Non-Patent Document 4). However, none of these existing agents are
satisfactory agents for essentially treating hypercalcemia or bone metabolic diseases,
and thereby the development of agents having high therapeutic efficacy is desired.

The term "bone metabolic disease" in the present invention means diseases
characterized by a substantial decrease in bone mass or an increase in blood calcium
concentration and diseases that require suppression of the bone resorption or the rate
of bone resorption for their prophylaxis or treatment.
Examples of such bone metabolic disease include osteoporosis, hypercalcemia,
bone metastasis of cancer, periodontal diseases, bone Paget's disease, and
osteoarthrosis.
The above term "osteoporosis" means a systemic disease in which, due to a
decrease in bone mass, the bone microarchitecture is disrupted and the mechanical
strength of bone is reduced, resulting in an increased risk of fractures. Examples of
osteoporosis include postmenopausal osteoporosis, senile osteoporosis, secondary
osteoporosis caused by steroid or immunosuppressive agent use, osteoclasis or
osteopenia due to rheumatoid arthritis, and osteopenia due to artificial joint
replacement.
The above term "treatment" means to cure or improve a disease or a symptom
or to suppress a symptom.
The above term "significantly decrease blood calcium concentration"
generally means to decrease the blood calcium concentration that is strictly
maintained at a constant value to a level lower than a general level. The decrease
ratio is preferably 0.1% or more, more preferably 0.5% or more, still more preferably
1% or more, and particularly more preferably 5% or more.
The above term "its pharmacologically acceptable salt" means a basic salt or
an acid salt produced by a reaction of a compound having Formula (1) of the present

47
invention, when the compound has an acidic group or a basic group, with a base or
an acid.
The pharmacologically acceptable "basic salt" of the compound having
Formula (I) of the present invention is preferably an alkali metal salt such as a
sodium salt, a potassium salt, or a lithium salt; an alkaline-earth metal salt such as a
magnesium salt or a calcium salt; an organic basic salt such as an N-
methylmorpholine salt, a triethylamine salt, a tributylamine salt, a
diisopropylethylamine salt, a dicyclohexylamine salt, an N-methylpipcridinc salt, a
pyridine salt, a 4-pyrrolidinopyridine salt, or a picoline salt; or an amino acid salt
such as a glycine salt, a lysine salt, an alginine salt, an ornithine salt, a glutamic acid
salt, or an aspartic acid salt, and preferably an alkali metal salt.
The pharmacologically acceptable "acid salt" of the compound having
Formula (I) of the present invention is preferably an inorganic acid salt, for example.
a hydrohalide such as hydrofluoride, hydrochloride, hydrobromide, or hydroiodide. a
nitrate, a perchlorate, a sulfate, or a phosphate; an organic acid salt, for example, a
lower alkanesulfonate such as a methanesulfonate, a trifluoromethanesulfonate. or an
ethane sulfonate, an arylsulfonate such as a benzenesulfonate or a p-toluenesulfonate.
an acetate, a malate, a fumarate, a succinate, a citrate, an ascorbatc, a tartrate, an
oxalate, or a maleate; or an amino acid salt such as a glycine salt, a lysine salt, an
alginine salt, an ornithine salt, a glutamic acid salt, or an aspartic acid salt, and most
preferably a hydrohalide.
The compound having Formula (I) or a pharmacologically acceptable salt
thereof of the present invention may become a hydrate by absorbing water or being
attached with water when the salt is left in the air or recrystallized, and such a
hydrate is included in the present invention.
The compound having Formula (I) or a pharmacologically acceptable salt
thereof of the present invention has an acrylamide structure in its molecule and
thereby can be present in two regioisomers, namely, (E)-isomer and (Z)-isomer. due

48
to the double bond. In the compound according to the present invention, both these
regioisomers and mixtures thereof are represented by a single Formula (I).
Therefore, the present invention includes both these regioisomers and mixtures
containing the regioisomers at any proportion and preferably includes mainly the (Z)-
isomer. The isomers of the mixtures can be separated by a known separation
method.
The compound having Formula (I) or a pharmacologically acceptable salt
thereof of the present invention has optical isomers when it has an asymmetric
carbon atom in its molecule. In the compound according to the present invention,
all optical isomers and mixtures thereof are represented by a single Formula (I).
Therefore, the present invention includes all these optical isomers and mixtures
containing the optical isomers at any proportion.
The compounds having Formula (I) of the present invention which have been
labeled with an isotope (for example, 3H, 14C, or 35S) are also included in the present
invention.
Preferred examples of the compound having Formula (1) of the present
invention are compounds having Formula (1-1), (1-2), or (1-3) described in the
following Tables 1, 2, and 3, but the present invention is not limited to these
compounds.
In the Tables, substituents are denoted by the following abbreviations. In a
substituent represented by a plurality of abbreviations, the substituent consists of the
substituents denoted by the abbreviations bound to each other. For example, 2-
cPrEtO denotes a 2-cyclopropylethoxy group.

The amido derivative which is an active ingredient of the drug of the present
invention or its pharmacologically acceptable salt is low in toxicity and is excellent
in bone resorption-suppressing activity. Therefore, the drug of the present invention
is particularly valuable as a prophylactic or therapeutic agent (in particular,
therapeutic agent) for osteoporosis.
When the compound having Formula (I), which is an active ingredient of the
drug of the present invention, or its pharmacologically acceptable salt is used as the
above-mentioned prophylactic or therapeutic agent (in particular, therapeutic agent).
the compound or the salt itself or a mixture with an optional pharmacologically
acceptable filler, diluent, or the like can be administered, for example, orally as a
tablet, a capsule, granules, powder, or syrup; or parenterally as an injection or a
suppository.
These formulations are prepared by widely known methods using additives
such as fillers (for example, organic fillers: sugar derivatives such as lactose, white
sugar, glucose, mannitol, and sorbitol; starch derivatives such as corn starch, potato
starch, a-starch, and dextrin; cellulose derivatives such as crystal cellulose; gum
arabic; dextran; and pullulan, and inorganic fillers: silicate derivatives such as light
anhydrous silicic acid, synthetic aluminum silicate, calcium silicate, and magnesium
aluminometasilicate; phosphates such as calcium hydrogen phosphate; carbonates
such as calcium carbonate; and sulfates such as calcium sulfate), lubricants (for
example, stearic acid, stearic acid metal salts such as calcium stearate, and
magnesium stearate; talc; colloidal silica; waxes such as bee gum and spermaceti;
boric acid; adipic acid; sulfuric acid salts such as sodium sulfate; glycol; fumaric
acid; sodium benzoate; D,L-leucine; fatty acid sodium salts; laurylsulfuric acid salts
such as sodium laurylsulfate and magnesium laurylsulfate; silic acids such as silicic
anhydride and silicate hydrate; and the above-mentioned starch derivatives), binders
(for example, hydroxypropylcellulose, hydroxypropylmefhylcellulosc,

92
polyvinylpyrrolidone, macrogol, and the same compounds as the above-mentioned
fillers), disintegrating agents (for example, cellulose derivatives such as low-
substituted hydroxypropylcellulose, carboxylmethylcellulose,
carboxylmethylcellulose calcium, and internally-crosslinked carboxylmethylcellulose
sodium; and chemically modified starch/cellulose such as carboxylmethyl starch,
carboxylmethyl starch sodium, and crosslinked polyvinylpyrrolidone), stabilizers (for
example, paraoxybenzoic acid esters such as methylparaben and propylparaben;
alcohols such as chlorobutanol, benzylalcohol, and phenylethylalcohol;
benzalkonium chloride; phenols such as phenol and cresol; thimerosal; dehydroacetic
acid; and sorbic acid), flavoring agents (for example, sweeteners, acidifiers, and
flavors which are usually used), and diluents.
The dosage and administration regimen vary depending on, for example, the
symptom and the age. Usually, the formulation is administered as follows:
For oral administration, the dose per administration is 0.001 to 100 mg/kg and
preferably 0.01 to 10 mg/kg.
In intravenous administration, the dose per administration is 0.0001 to 10
mg/kg and preferably 0.001 to 1 mg/kg.

(Test Example 1) Evaluation of blood calcium concentration-decreasing
activity
The blood calcium concentration in a living body is strictly controlled and
constantly maintained by intestinal absorption and urinary excretion and release
(bone resorption) and adhesion (bone formation) in bone tissues. In an immature rat,
which is very active in bone resorption and bone formation, the blood calcium
concentration is significantly decreased by strongly suppressing bone resorption.
The bone resorption-suppressing activity of compounds according to the present
invention was evaluated by administering the compounds to immature rats and
observing decreases in blood calcium concentration as an index of the activity.
The test was conducted using 4-week old male Wistar rats fasted for 12 to 24
hours. Each compound to be tested was suspended in 0.5% methyl cellulose (MC).
The suspension was orally administered to the rats at a dose of 5 mT/kg. Similarly,
rats of a normal control group were administered with 0.5% MC alone. Then, blood
was drawn from rat jugular vein under ether anesthesia 6 hours after the
administration of each test compound or 0.5% MC. The blood was immediately
centrifuged (10000 rpm, 5 minutes) at room temperature to separate serum. The
calcium concentration of each serum was measured by an autoanalyzer (JEOL, JCA-
BM2250). Five rats were used for each test group.
The test results are shown in Table 5 below. The evaluation was conducted
by a comparative test with the normal control group and based on the serum calcium
concentration-decreasing rate (%) calculated according to the following formula:

206
Serum calcium concentration-decreasing rate (%) = ([serum calcium concentration in
normal control group] - [serum calcium concentration in test compound
administration group]/[serum calcium concentration in normal control group]) x 100.
(Table 5)

Test compound Administration dose Serum calcium concentration-
(mg/kg) decreasing rate (%)

Example 9 20 29.3
Example 11 20 30.6
Example 14 10 33.2
Example 16 10 27.2
In general, a constant blood calcium concentration should be strictly
maintained, but the blood calcium concentrations were decreased by administering
the compounds according to the present invention. This result suggests that the
blood calcium concentration-decreasing activity of the compounds according to the
present invention is high.
(Test Example 2) Evaluation of bone density decrease-suppressing activity
and anti-arthritic activity
In rheumatoid arthritis, not only swelling and pain caused by arthritis but also
systemic bone mass decrease and articular destruction caused by a significant
increase in bone resorption are observed. The effects of the compounds according
to the present invention in suppressing the bone mass decrease and the paw volume
increase caused by arthritis were evaluated using adjuvant arthritis model rats, which
exhibit arthritis similar to human rheumatoid arthritis.
The test was conducted using 8-week old female Lewis rats. Mycobacterium
butyricum cells which were killed by heat were ground in an agate mortar, suspended
in liquid paraffin sterilized by dry heat to a concentration of 2 mg/mL, and treated

207
with ultrasound to prepare an adjuvant. Under ether anesthesia, rats in a control
group other than a normal control group and rats in a test compound administration
group were intradermally injected with 0.05 mL of this adjuvant each time (1.0
mL/rat in total) at two portions of the base of the tail. Starting from 14 days after
the injection of the adjuvant, each rat was orally administered with 5 mL/kg of a test
compound suspended in 0.5% MC once a day for 7 days. Similarly, the rats of the
control group were administered with 0.5% MC alone. On the 21 st day after the
adjuvant injection, hind paw volumes were measured by using a paw edema volume
determining device (MUROMACHI KIKAI, TK-101 CMP). Then, the thighbone
was biopsied. The thighbone was, after removing soft tissues, sufficiently fixed,
dehydrated, and dried using ethanol. The bone density of the thighbone was
measured with a bone density analyzer (Aloka, DOS-600 EX-MR). Five rats were
used for each test group.
The test results are shown in Table 6 below.
The evaluation was conducted by comparison tests with the normal control group
and the control group and based on the bone density decrease-suppressing rate (%)
and the paw edema-suppressing rate (%) calculated according to the following
formulae:
Bone density decrease-suppressing rate (%) = (1-([thighbone bone density in normal
control group] - [thighbone bone density in test compound administration
group])/[thighbone bone density in normal control group] - [thighbone bone density
in control group])) x 100
Paw edema-suppressing rate (%) = (l-([paw volume of test compound administration
group] - [paw volume in normal control group])/[paw volume in control group] -
[paw volume in normal control group])) x 100 ;

The bone density decrease and the paw volume increase were significantly
suppressed by administering the compounds according to the present invention.
Thus, advantageous effects of the compounds according to the present invention as
prophylactic or therapeutic drugs for bone metabolic diseases and inflammation were
confirmed.
Industrial Applicability
The drugs according to the present invention have blood calcium
concentration-decreasing effect and bone mass decrease-suppressing effect due to
their excellent bone resorption-suppressing effects and are low in toxicity.
Therefore, the drugs are useful as prophylactic or therapeutic drugs for bone
metabolic diseases, for example, osteoporosis, hypercalcemia, bone metastasis of
cancer, periodontal disease, bone Paget's disease, and osteoarthrosis, in mammals
(such as human, ape, dog, cat, horse, and hog, in particular, human).
