Quinolinone derivatives as tyrosine kinase inhibitors.

This invention pertains generally to treating diseases characterized by angiogenesis including cancer. More specifically, the invention described herein pertains to treating diseases characterized by activity of vascular endothélial growth factor receptor tyrosine kinases. The présent invention provides, small molécule inhibitors of vascular endothélial growth factor receptor tyrosine kinase, ' pharmaceutical formulations containing such inhibitors, methods of treating patients with such pharmaceutical formulations, and to methods of preparing such pharmaceutical formulations and inhibitors.

BACKGROUND OF THE INVENTION

Capillaries reach into almost ail tissues of the human body and supply tissues with oxygen and nutrients as well as removing waste products. Under typical conditions, the endothélial cells lining the capillaries do not divide, and capillaries, therefore, do not normally increase in number or size in a human adult. Under certain normal conditions, however, such as when a tissue is damaged, or during certain parts of the menstrual cycle, the capillaries begin to proliferate rapidly. This process of forming new capillaries from pre-existing blood vessels is known as angiogenesis or neovascularization. See Folkman, J. Scientifîc American 275, 150-154 (1996). Angiogenesis during wound healing is an example of pathophysiological neovascularization during adult life. During wound healing, the additional capillaries provide a supply of oxygen and nutrients, promote granulation tissue, and aid in waste removal. After termination of the healing process, the capillaries normally regress. Lymboussaki, A. “Vascular Endothélial Growth Factors and their Receptors in Embryos, Adults, and in Tumors” Academie

Angiogenesis also plays an important rôle in the growth of cancer cells. It is known that once a nest of cancer cells reaches a certain size, roughly 1 to 2 mm in diameter, the cancer cells must develop a blood supply in order for the tumor to grow larger as diffusion will not be sufficient to supply the cancer cells with enough oxygen and nutrients. Thus, inhibition of angiogenesis is expected to hait the growth of cancer cells.

Recgptor tyrosine kinases (RTKs) are transmembrane polypeptides that regulate developmental cell growth and différentiation, remodeling and régénération of adult tissues. Mustonen, T. et al., J. Cell Biology 129, 895-898 (1995); van der Geer, P. et al. Ann Rev. Cell Biol. 10, 251-337 (1994); Polypeptide ligands known as growth factors or cytokines, are known to activate RTKs. Signaling RTKs involves ligand binding and a shift in conformation in the external domain of the receptor resulting in its dimerization. Lymboussaki, A. “Vascular Endothélial Growth Factors and their Receptors in Embryos, Adults, and in Tumors” Academie Dissertation, University of Helsinki, Molecular/Cancer Biology Laboratory and Départaient of Pathology, Haartman Institute, (1999); Ullrich, A. et al., Cell 61, 203-212 (1990). Binding of the ligand to the RTK results in receptor trans-phosphorylation at spécifie tyrosine residues and subséquent activation of the catalytic domains for the phosphorylation of cytoplasmic substrates. Id.

Two subfamilies of RTKs are spécifie to the vascular endothélium. These include the vascular endothélial growth factor (VEGF) subfamily and the Tie receptor subfamily. Class ΠΙ RTKs include VEGFR-1, VEGFR-2, and VEGFR-3. Shibuya, M. et al., Oncogene 5, 519-525 (1990); Terman, B. et al., Oncogene 6, 1677-1683 (1991); Aprelikova, O. et al., Cancer Res. 52, 746-748 (1992).

Members of the VEGF subfamily hâve been described as being able to induce vascular permeability and endothélial cell prolifération and further

-3012428 identified as a major inducer of angiogenesis and vasculogenesis. Ferrara, N. et al., Endocrinol. Rev. 18, 4-25 (1997). VEGF is known to specifîcally bind to RTKs including VEGFR-1 and VEGFR-2. DeVries, C. et al., Science 255, 989991 (1992); Quinn, T. et al., Proc. Natl. Acad. Sci. 90, 7533-7537 (1993). VEGF stimulâtes the migration and prolifération of endothélial cells and induces angiogenesis both in vitro and in vivo. Connolly, D. et al., J. Biol. Chem. 264, 20017-20024 (1989); Connolly, D. et al., J. Clin. Invest. 84, 1470-1478 (1989); Ferrara, N. et al., Endocrino. Rew. 18, 4-25 (1997); Leung, D. et al., Science 246, 1306-1309 (1989); Plouet, J. et al., EMBO J 8, 3801-3806 (1989).

Because angiogenesis is known to be critical to the growth of cancer and to be controlled by VEGF and VEGF-RTK, substantial efforts hâve been undertaken to develop therapeutics that are antagoniste of VEGF-RTK to thereby inhibit or retard angiogenesis, and, hopefully, interfère or stop tumor prolifération.

A wide variety of chemical compounds and compositions hâve been reported as having activity against one of more the VEGF-RTKs. Examples include quinoline dérivatives such as described in WO 98/13350, aminonicotinamide dérivatives (see, e.g., WO 01/55114), antisense compounds (see, e.g., WO 01/52904), peptidomimetics (see, e.g., WO 01/52875), quinazoline dérivatives (see, e.g., U.S. Patent No. 6,258,951) monoclonal antibodies (see, e.g., EP 1 086 705 Al), various 5,10,15,20-tetraaryl-porphyrins and 5,10,15-triaryI-corroles (see, e.g., WO 00/27379), heterocyclic alkanesulfonic and alkane carboxylic acid dérivatives (see, e.g., DE19841985), oxindolylquinazoline dérivatives (see, e.g., WO 99/10349), 1,4-diazaanthracine dérivatives (see, e.g., U.S. Patent No. 5,763,441), and cinnoline dérivatives (see, e.g., WO 97/34876), and various indazole compounds (see, e.g., WO 01/02369 and WO 01/53268).

Various indolyl substituted compounds hâve recently been disclosed in WO 01/29025, WO 01/62251, and WO 01/62252, and various benzimidazolyl compounds hâve recently been disclosed in WO 01/28993. These compounds are reportedly capable of inhibiting, modulating, and/or regulating signal transduction _4_

012428 of both receptor-type and non-receptor tyrosine kinases. Some of the disclosed compounds contain a quinolone fragment bonded to the indolyl or benzimidazolyl group.

The synthesis of 4-hydroxy quinolone and 4-hydroxy quinoline dérivatives is disclosed in a number of references. For example, Ukrainets et al. hâve disclosed the synthesis of 3-(benzimidazol-2-yl)-4-hydroxy-2-oxo-l,2dihydroquinoline. Ukrainets, I. et al., Tet. Lett. 42, 7747-7748 (1995); Ukrainets, I. et al., Khimiya Geterotsiklicheskikh Soedinii, 2, 239-241(1992). Ukrainets has also disclosed the synthesis, anticonvulsive and antithyroid activity of other 4hydroxy quinolones and thio analogs such as lH-2-oxo-3-(2-benzimidazolyl)-4hyrdoxyquinoline. Ukrainets, I. et al., Khimiya Geterotsiklicheskikh Soedinii, 1, 105-108 (1993); Ukrainets, I. et al., Khimiya Geterotsiklicheskikh Soedinii, 8, 1105-1108 (1993); Ukrainets, I. étal., Chem. Heterocyclic Comp. 33, 600-604, (1997).

The synthesis of various quinoline dérivatives is disclosed in WO 97/48694. These compounds are disclosed as capable of binding to nuclear hormone receptors and being useful for stimulating osteoblast prolifération and bone growth. The compounds are also disclosed as being useful in the treatment or prévention of diseases associated with nuclear hormone receptor families.

Various quinoline dérivatives in which the benzene ring of the quinolone is substituted with a sulfur group are disclosed in WO 92/18483. These compounds are disclosed as being useful in pharmaceutical formulations and as médicaments.

Quinolone and coumarm dérivatives hâve been disclosed as having use in a variety of applications unrelated to medicine and pharmaceutical formulations. References that describe the préparation of quinolone dérivatives for use in photopolymerizable compositions or for luminescent properties include: U.S. Patent No. 5,801,212 issued to Okamoto et al.; JP 8-29973; JP 7-43896; JP 6-9952; JP 63-258903; EP 797376; and DE 23 63 459.

Iodination of aniline containing compounds: ïodination was done by a similar procedure as in J. Med. Chem. 2001, 44, 6, 917-922. The anthranilic ester in EtOH was added to a mixture of silver sulfate (1 équivalent) and L· (1 équivalent). The reaction was typically doue after 3 hours at room. température.

The reaction was filtered through celite and concentrated. The residue was taken up in EtOAc and washed with aqueous saturated NaHCÛ3 (3x), water (3x), brine (Ix), dried (MgSO4), filtered, and concentrated. The crude product (-5 g) was dissolved in MeOH (60-100 ml), NaOH 6N (25 ml), and water (250 ml). The reactions were typically done after beating at 70-80°C for 4 hours. The reaction mixture was extracted with EtOAc (2x), neutralized with aqueous HCI, filtered to collect the solids, and the solid products were washed with water. The products 15 were dried in vacuo.

Assay Procedures

In vitro kinase assays for receptor tyrosine kinases

The kinase activity of various protein tyrosine kinases can be measured by providing ATP and a suitable peptide or protein tyrosine-containing substrate, and assaying the transfer of phosphate moiety to the tyrosine residue. Recombinant proteins corresponding to the cytoplasmic domains of the flt-1 (VEGFR1), KDR (VEGFR2), and hFGF receptors were expressed in Sf9 insect cells using a Baculovirùs expression system (InVitrogen) and purified via Glu antibody interaction (for Glu-epitope tagged constructs) or by Métal Ion Chromatography (for Hise tagged constructs). For each assay, test compounds were serially diluted in DMSO then mixed with an appropriate kinase reaction buffer plus ATP. Kinase protein and an appropriate biotinylated peptide substrate were added to give a final volume of 100 pL, reactions were incubated for 1-2 hours at room température and stopped by the addition of 50 pL of 45 mM EDTA, 50 mM Hepes pH 7.5. Stopped reaction mix (75 pL) was transferred to a streptavidin coated microtiter plate (Boehringer Mannheim) and incubated for 1 hour. Phosphorylated peptide product was measured with the DELFIA time-resolved fluorescence system (Wallac), using a Eu-labeled anti-phosphotyrosine antibody PT66 with the modification that the DELFIA assay buffer was supplemented with 1 mM MgCh for the antibody dilution. Time resolved fluorescence was read on a Wallac 1232 DELFIA fluorometer. The concentration of each compound for 50% inhibition (ICso) was calculated by non-linear régression using XL Fit data analysis software.

Flt-1, KDR, and bFGFR kinases were assayed in 50 mM Hepes pH 7.0, 2 mM MgCh. 10 mM MnCh. 1 mM NaF, 1 mM DTT, 1 mg/ml BSA, 2 pM ATP, and 0.42 pM biotin-GGGGQDGKDYIVLPI-NH:. Flt-1, KDR, and bFGFR kinases were added at 0.1 pg/mL, 0.05 pg/mL, or 0.1 pg/mL respectively.
