AMG-628 is an effective and ATP-competitive RAF kinase inhibitor. AMG-628 has been shown to inhibit growth and induce cell cycle arrest and apoptosis in colon and melanoma cell lines with B-RAFV600E mutations.
CAY10717 is a multi-targeted kinase inhibitor that exhibits greater than 40% inhibition of 34 of 104 kinases in an enzymatic assay at a concentration of 100 nM. It has activity at multiple oncogenic kinases, with IC50 values less than 50 nM against wild-type EGFR and ABL and mutant ABLG250E, ABLY253F, ABLE255K, and B-RafV600E. CAY10717 is highly cytotoxic against a cancer cell panel that includes chemotherapy-sensitive and -resistant cell lines (EC50s = 0.4-158 nM). It also inhibits the growth of human umbilical vein endothelial cells (HUVECs; EC50 = 34 nM), a model for tumor angiogenesis.
RO5068760 , a substituted hydantoin, is a potent, highly selective, non-adenosine triphosphate (ATP)-competitive MEK1 2 inhibitors. RO5068760 shows significant efficacy in a broad spectrum of tumors with aberrant mitogen-activated protein kinase pathway activation. In vitro, RO5068760 demonstrates MEK1 kinase inhibitory activity with an IC50 of 0.025 μM in a cRaf MEK ERK cascade assay RO5068760 showed superior efficacy in tumors harboring B-RafV600E mutation.
