Definitions
- the present invention relates to new substituted quinazoline, quinoxaline, quinoline and isoquinoline compounds and pharmaceutically acceptable salts, esters or prodrugs thereof, compositions of the new compounds together with pharmaceutically acceptable carriers, and uses of the new compounds, either alone or in combination with at least one additional therapeutic agent, in the prophylaxis or treatment of cancer.
- the Raf serine/threonine kinases are essential components of the Ras/Mitogen- Activated Protein Kinase (MAPK) signaling module that controls a complex transcriptional program in response to external cellular stimuli.
- Raf genes code for highly conserved serine-threonine-specific protein kinases which are known to bind to the ras oncogene. They are part of a signal transduction pathway believed to consist of receptor tyrosine kinases, p21 ras, Raf protein kinases, Mekl (ERK activator or MAPKK) kinases and ERK (MAPK) kinases, which ultimately phosphorylate transcription factors.
- Raf kinases are activated by Ras and phosphorylate and activate two isoforms of Mitogen-Activated Protein Kinase Kinase (called Mekl and Mek2), that are dual specificity threonine/tyrosine kinases.
- Both Mek isoforms activate Mitogen Activated Kinases 1 and 2 (MAPK, also called Extracellular Ligand Regulated Kinase 1 and 2 or Erkl and Erk2).
- MAPK Mitogen Activated Kinases 1 and 2
- the MAPKs phosphorylate many substrates including transcription factors and in so doing set up their transcriptional program.
- Raf kinase participation in the Ras/MAPK pathway influences and regulates many cellular functions such as proliferation, differentiation, survival, oncogenic transformation and apoptosis. Both the essential role and the position of Raf in many signaling pathways have been demonstrated from studies using deregulated and dominant inhibitory Raf mutants in mammalian cells as well as from studies employing biochemical and genetic techniques model organisms.
- Raf-1 phosphorylates and activates Mekl, resulting in the propagation of the signal to downstream effectors, such as MAPK (mitogen-activated protein kinase) (Crews et al. (1993) Cell 74:215).
- MAPK mitogen-activated protein kinase
- the Raf serine/threonine kinases are considered to be the primary Ras effectors involved in the proliferation of animal cells (Avruch et al. (1994) Trends Biochem. Sci. 19:279).
- Raf kinase has three distinct isoforms, Raf-1 (c-Raf), A-Raf, and B-Raf, distinguished by their ability to interact with Ras, to activate MAPK kinase pathway, tissue distribution and sub-cellular localization (Marias et al., Biochem. J 351: 289-305, 2000; Weber et. al., Oncogene 19:169-176, 2000; Pritchard et al, Mol. Cell. Biol. 15:6430-6442, 1995). Recent studies have shown that B-Raf mutation in the skin nevi is a critical step in the initiation of melanocytic neoplasia (Pollock et.
- Inhibitors of Raf/MEK/ERK pathway at the level of Raf kinases can potentially be effective as therapeutic agents against tumors with over-expressed or mutated receptor tyrosine kinases, activated intracellular tyrosine kinases, tumors with aberrantly expressed Grb2 (an adapter protein that allows stimulation of Ras by the Sos exchange factor) as well as tumors harboring activating mutations of Raf itself.
- Grb2 an adapter protein that allows stimulation of Ras by the Sos exchange factor
- an inhibitor of Raf-1 kinase, that also inhibits B-Raf has shown promise as a therapeutic agent in cancer therapy (Crump, Current Pharmaceutical Design 8: 2243- 2248, 2002; Sebastien et. al., Current Pharmaceutical Design 8: 2249-2253, 2002).
