Definitions

  • This invention relates to novel substituted pyridine compounds, and salts thereof, which are useful in the treatment of hyperproliferative diseases, such as cancers, in mammals.
  • the invention relates to compounds that inhibit the protein tyrosine kinase activity, resulting in the inhibition of inter- and/or intra-cellular signaling.
  • This invention also relates to a method of using such compounds in the treatment of hyperproliferative diseases in mammals, especially humans, and to pharmaceutical compositions containing such compounds.
  • Protein kinases are key regulators of cell function that constitute one of the largest and most functionally diverse gene families. By adding phosphate groups to substrate proteins, they direct the activity, localization and overall function of many proteins, and serve to orchestrate the activity of many cellular processes. Kinases are particularly prominent in signal transduction and co-ordination of complex functions such as the cell cycle. Of the 518 human protein kinases, 478 belong to a single superfamily whose catalytic domains are related in sequence. These can be clustered into groups, families and sub-families, of increasing sequence similarity and biochemical function.
  • a partial list of such kinases include abl, AATK, ALK, Akt, Axl, bmx, bcr-abl,
  • Receptor tyrosine kinases are a diverse group of transmembrane proteins that act as receptors for cytokines, growth factors, hormones and other signaling molecules. Receptor tyrosine kinases (RTKs) are expressed in many cell types and play important roles in a wide variety of cellular processes, including growth, differentiation and angiogenesis. Activation of the kinase is effected by binding of a ligand to the extracellular domain, which induces dimerization of the receptors. Activated receptors auto-phosphorylate tyrosine residues outside the catalytic domain via cross-phosphorylation. This auto-phosphorylation stabilizes the active receptor conformation and creates phosphotyrosine docking sites for proteins that transduce signals within the cell.
  • RTKs Receptor tyrosine kinases
  • Receptor tyrosine kinases are hyper-activated (through receptor activating mutations, gene amplification, growth factor activation, etc.) in many human solid tumors and hematological malignancies. RTK's elevated activation contributes to tumourigenesis factors such as hyperplasia, survival, invasion, metastasis and angiogenesis. Inhibition of receptor tyrosine kinases proved to be effective strategies in cancer therapy (Sharma et al., "Receptor tyrosine kinase inhibitors as potent weapons in war against cancers", Curr. Pharm. Des., 2009, 15, 758).
  • ALK Anaplastic lymphoma kinase
  • NPM nucleophosmin
  • ALK anaplastic large-cell lymphoma
  • ALK fusions were also found in the human sarcomas called inflammatory myofibroblastic tumors (IMTs). Studies suggested that the ALK fusion, TPM4-ALK, may be involved in the genesis of a subset of esophageal squamous cell carcinomas. Moreover, studies have implicated various mutations of the ALK gene in both familial and sporadic cases of neuroblastoma. ALK mutations in neuroblastoma cells results in constitutive ALK phosphorylation and attenuation.
  • EML4-ALK fusion gene comprised of portions of the echinoderm microtubule-associated protein-like 4 (EML4) gene and the ALK gene were identified in NSCLC cells.
  • EML4-ALK fusion transcript was detected in approximately 3- 7% of NSCLC patients examined.
  • Experimental evidence from in vitro and in vivo studies demonstrated oncogenic transforming activity of the EML4-ALK fusion proteins and reinforced the pivotal role of EML4-ALK in the pathogenesis of NSCLC in humans (Soda et al., "Identification of the transforming EML4-ALK fusion gene in non-small-cell lung cancer", Nature, 2007, 448, 561).
  • JAK3-STAT3 pathway and the PI3K-Akt pathway have been shown to be vital primarily for cell survival and phenotypic changes (Chiarle et al., "The anaplastic lymphoma kinase in the pathogenesis of cancer", Nat. Rev. Cancer, 2008, 8, 11; Barreca et al, "Anaplastic lymphoma kinase (ALK) in human cancer", J. Mol. Endocrinol., 2011, 47, Rl 1).
  • c-Met also referred to as hepatocyte growth factor receptor (HGFR)
  • HGFR hepatocyte growth factor receptor
  • HGF also known as scatter factor (SF).
  • SF scatter factor
  • c-Met is also implicated in atherosclerosis and lung fibrosis. Invasive growth of certain cancer cells is drastically enhanced by tumor- stromal interactions involving the HGF/c-Met pathway.
  • c-Met signaling is involved in the progression and spread of several cancers and an enhanced understanding of its role in disease have generated considerable interest in c-Met as major targets in cancer drug development (Migliore et al., "Molecular cancer therapy: can our expectation be MET", Eur. J.
  • Crizotinib is an ATP-competitive small molecule ALK inhibitor, which also displays activity against the c-Met receptor tyrosine kinase.
  • the FDA recently approved crizotinib (Pfizer' s XALKORI ® , originally known as PF-02341066) for treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC), in which tumor cells exhibit rearrangements in the anaplastic lymphoma kinase (ALK) gene.
  • Crizotinib is administered 250 mg twice daily. Following oral single-dose administration, crizotinib was absorbed with median time to achieve peak concentration of 4 to 6 hours. Following crizotinib 250 mg twice daily, steady state was reached within 15 days and remained stable, with a median accumulation ratio of 4.8 (XALKORI ® FDA- Approved Patient Labeling, Pfizer Inc. February 2012).
  • crizotinib As seen with other targeted cancer drugs, patients with ALK-positive NSCLC eventually relapse on crizotinib. The development of acquired resistance is clearly the major hurdle preventing targeted therapies such as crizotinib from having an even more substantial impact on patients (Alice et al, Nat. Rev. Drug Discovery, 2011, 10, 897).

Abstract

La présente invention concerne de nouveaux composés de pyridine substituée, leurs sels de qualité pharmaceutique et des formulations les incluant utiles pour moduler l'activité de la protéine tyrosine kinase ainsi que pour moduler des activités cellulaires telles que la prolifération, la différenciation, l'apoptose, la migration et l'invasion. L'invention concerne en outre des compositions de qualité pharmaceutique comprenant de tels composés ainsi que des méthodes d'utilisation des compositions dans le traitement de troubles hyperprolifératifs chez des mammifères, en particulier chez des humains.
