Full Text The present invention relates to aminopyridine compounds as protein kinase inhibitors for the treatment of cancer.
Field of the Invention
The invention relates generally to novel chemical compounds and methods. More particularly, the invention provides novel pyrazole-substituted aminoheteroaryl compounds, particularly aminopyridines and aminopyrazines, having protein tyrosine kinase activity, and methods of synthesizing and using such compounds. Preferred compounds are c-Met inhibitors useful lor the treatment of abnormal cell growth, such as cancers.
Background
The hepatocyte growth factor (HGF) receptor (c-MET or HGFR) receptor tyrosine kinase (RTK) has been shown in many human cancers to be involved in oncogenesis, tumor progression with enhanced ceil motility and invasion, as well as metastasis (see, e.g., Ma, P.C., Maulik, G., Christensen, J. & Salgia, R. (2003b). Cancer Metastasis Rev, 22, 309-25; Maulik, G„ Shrikhande, A., Kijima, T., Ma, P.C., Morrison, P.T. & Salgia, R. (2002b). Cytokine Growth Factor Rev, 13, 41-59). c-MET (HGFR) can be activated through overexpression or mutations in various human cancers including small cell lung cancer (SCLC) (Ma, P.C., Kiitma, T„ Maulik, G., Fox, E.A., Sattler, M., Griffin. J.D., Johnson, B.E. & Salgia, R. . (2003a). Cancer Res, 63,6272-6281).
c-MET is a receptor tyrosine kinase that is encoded by the Met proto-oncogene and transduces the biological effects of hepatocyte growth factor (HGF), which is also referred to as scatter factor (SF). Jiang et al., Crit. Rev. Oncol. Hematol. 29: 209-248 (1999). c-MET and HGF are expressed in numerous tissues, although their expression is normally confined predominantly to cells of epithelial and mesenchymal origin, respectively. c-MET and HGF are required for normal mammalian development and have been shown to be important in cell migration, cell proliferation and survival, morphogenic differentiation, and organization of 3-dimensional tubular structures (e.g., renal tubular cells, gland formation, etc.). In addition to Its effects on epithelial cells, HGF/SF has been reporte'd to be an angiogenic factor, and c-MET signaling in endothelial cells can induce many of the cellular responses necessary for angiogenesis (proliferation, motility, invasion).
The c-MET receptor has been shown to be expressed in a number of human cancers. c-Met and its iigand, HGF, have also been shown to be co-expressed at elevated levels in a variety of human cancers (particularly sarcomas). However, because the receptor and Iigand are usually expressed by different cell types, c-MET signaling is most commoniy regulated by tumor-stroma (tumor-host) interactions. Furthermore, c-MET gene amplification, mutation, and rearrangement have been observed in a subset of human cancers. Families with germfine mutations that activate c-MET kinase are prone to multiple kidney tumors as well as tumors in other tissues. Numerous studies have correlated the expression of c-MET and/or HGF/SF with the state of disease progression of different types of cancer (including iung, colon, breast, prostate, liver, pancreas, brain, kidney, ovaries, stomach, skin, and bone cancers). Furthermore, the overexpression of c-MET or HGF have been shown to correlate with poor prognosis and disease outcome in a number of major human cancers including lung, liver, gastric, and breast. c-MET has also been directly implicated in cancers without a successful treatment regimen such as pancreatic cancer, glioma, and hepatocellular carcinoma.
Examples of c-MET (HGFR) inhibitors, their synthesis and use, can be found in U.S. Paisnt Application Serial No. 10/786,610, entitled "Aminoheleroaryl Compounds as Protein Klrvase Inhibitors", fifed February 26, 2004, and corresponding international application PCT/US20Q4/005495 of the same title, filed February 26, 2004, the disclosures of which are incorporated herein by reference in their entireties.
It would be desirable to have novel c-MET {HGFR) inhibitors and methods of using such inhibitor's for the treatment of abnormal cell growth, such as cancer.

The general procedure is as follows: compounds and kinase assay reagents are introduced into test wells. The assay is initiated by addition of the kinase enzyme. Enzyme inhibitors reduce the measured activity of the enzyme.
In the .continuous-coupled spectrophotometric assay the time-dependent production of ADP by the kinase is determined by analysis of the rate of consumption of NADH by measurement of the decrease in absorbance at 340 nm. As the PK produces ADP it is re-converted to ATP by reaction with phosphoenol pyruvate and pyruvate kinase. Pyruvate is also produced in this reaction. Pyruvate is subsequently converted to laclate by reaction with lactate dehydrogenase, which simultaneously converts NADH to NAD. NADH has a measurable absorbance at 340 nm whereas NAD does not.
The presently preferred protocol for conducting the continuous-coupled spectrophotometric experiments for specific PKs is provided below. However, adaptation of this protocol for determining the activity of compounds against other RTKs, as well as for CTKs and STKs, is weU within the scope of knowledge of those skilled in the art.

The following In vitro assays may be used to determine the level of activity and effect of the different compounds of the present invention on one or more of the PKs. Similar assays can be designed along the same lines for any PK using techniques well known in the art.
Several of the assays described herein are performed in an ELISA (Enzyme-Linked Immunosorbent Sandwich Assay) format (Voder, et al., 1980, "Enzyme-Linked Immunosorberrt Assay," Manual of Clinical Immunology, 2d ed., Rose and Friedman, Am. Soc. Of Microbiology, Washington, D.C., pp. 359-371). General procedure is as follows: a compound is introduced to cells expressing the test kinase, either naturally or recombinantly, for a selected period of lime after which, if the test kfnase is a receptor, a llgand known to activate the receptor is added. The cells are lysed and the lysate is transferred to the wells of an ELISA plate previously coated with a specific antibody recognizing the substrate of the enzymatic phosphorylation reaction. Non-substrate components of the cell lysate are washed away and the amount of phosphorylation on the substrate is detected with an antibody specifically recognizing phosphotyrosine compared with control cells that were not contacted with a test compound.
The presently preferred protocols for conducting the ELISA experiments for specific PKs is provided below. However, adaptation of these protocols for determining the activity of compounds against other RTKs, as well as for CTKs and STKs, Is well within the scope of knowledge of those skilled in the art.
Other assays described herein measure the amount of DNA made in response to activation of a test kinase, which is a general measure of a proliferate response. General procedure for this assay is as follows: a compound Is introduced to cells expressing the test kinase, either naturally or recombinanily, for a selected period of time after which, if the test kinase is a receptor, a ligand known to activate the receptor Is added. After incubation at least overnight, a DNA labeling reagent such as 5-bromodeoxyuridine (Brdll) or H9-thymidine is added. The amount of labeled DNA is detected with either an anti-BrdU antibody or by measuring radioactivity and is compared to control cells not contacted with a test compound.

A549 cells (ATCC) were used in this assay. Cells were seeded In the growth media (RPMI + 10%FBS) into 96 well plates and cultured overnight at 37 *C for attachment. Cells were exposed to the starvation media (RPMI + 0.05% BSA). Dilutions of the inhibitors were added to the plates and incubated at 37 °C for 1 hour. Cells were then stimulated by adding 40 ng/ml HGF for .15 minutes. Cells were washed once with 1mM Na3V(X, in H8SS and then lysed. The lysates were diluted with 1mM NaaVO* in HBSS and transferred to a 96 well goat ant-rabbit coated plate (Pierce) which was pre-coated with anti-HGFR antibody (Zymed Laboratories). The piates were incubated overnight at 4 °C and washed with 1 % Tween 20 in PBS for seven times. HRP-PY20 (Santa Cruz) was diluted and added to the plates for 30 minutes incubation. Plates were then washed again and TMB peroxidase substrate (Kirkegaard & Perry) was added and incubated for 10 minutes. The reaction was then stopped by adding 0.09N H2SO4. Plates were measured at OD-450 nm using a spectrophotometer. IC50 values were calculated by curve fitting using a four-parameter analysis.
