描述 The RAS/RAF signaling pathway is an important mediator of tumor cell proliferation and angiogenesis. Among them, B-RAF is the most frequently mutated protein kinase in human cancers. Vemurafenib is a selective inhibitor of B-RafV600E mutant with IC50 value of 31nM (measured by enzymatic activity) displays similar potency c-RAF-1 (IC50=48nM), selective against many other kinases, including wild-type B-RAF (IC50=100nM)[1]. Vemurafenib potently and selectively inhibited proliferation in those melanoma cell lines expressing B-RafV600E mutant but not BRAF-WT. Vemurafenib can inhibit p-MEK and p-ERK in B-RafV600E- expressing melanoma cell lines, Colo829 and LOX (>0.24μM, for 2h), as well as in WM2664 and WM1341D cell lines (>0.24μM, for 2h), which expresses BRAFV600D and BRAFV600R, respectively. However, Vemurafenib showed more variable effect on p-MEK and p-ERK of cell lines that do not express codon 600 BRAF mutations, such as CHL-1 (BRAFWT) and SK-MEL2 (BRAFWT), and HMVII (BRAFG469V) cell line. Vemurafenib possessed good pharmacodynamics as an association between plasma concentration and inhibition of p-MEK and p-ERK can be observed, with the highest plasma concentration (124 μmol/L at 2h) corresponding to the highest mean percent inhibition of phosphorylation (70.5% for MEK and 52% for ERK)[2]. Oral gavage with Vemurafenib (6/20mg/kg, QD, or 20mg/kg, BID) demonstrated dose-dependent inhibition of tumour growth, with higher exposures (25/75mg/kg, BID) resulting in tumour regression, in COLO205 B-RafV600E mutant xenografts[1].
作用机制 Vemurafenib is an ATP-competitive inhibitor of mutant BRAF.[1]
