TAK-632 is a selective inhibitor of BRAF, CRAF and BRAF-V600E kinase with IC50 value of 8.3 nM, 1.4 nM and 2.4 nM .
RAF kinases are a family of three serine/threonine-specific protein kinases and play an important role in the RAS-RAF-MEK-ERK signal transduction cascade, as well as the mitogen-activated protein kinase (MAPK) cascade .
TAK-632 is a potent pan-RAF kinase inhibitor and has a higher selectivity compared with the reported pan-RAF kinase inhibitor vemurafenib. When tested with SK-MEL-2 cells, TAK-632 showed induction on the BRAF-CRAF dimmers formation in a dose-dependent manner. In melanoma cell lines A375 and SK-MEL-2, TAK-632 exhibited significant antiproliferative effects with GI50 value of 6 nom/L and 11 nom/L, respectively .
In mouse model with SK-MEL-2 subcutaneous xenograft, oral administration of TAK-632 caused significant reduction of phosphorylated ERK and tumor growth at the dose of 60 or 120 mg/kg/d once daily for 21 days without severe toxicity .
It is also reported that TAK-632 is a potent inhibitor of pERK with IC50 value of 25 nM .
