Biological Activity

Description SB590885 is a potent B-Raf inhibitor with Ki of 0.16 nM in a cell-free assay, 11-fold greater selectivity for B-Raf over c-Raf, no inhibition to other human kinases.
Targets
B-Raf
(Cell-free assay)
0.16 nM(Ki)
In vitro SB590885 displays significant selectivity for B-Raf over c-Raf with Ki of 0.16 nM over 1.72 nM. This compound is a more potent inhibitor than the previously described Raf/VEGFR kinase inhibitor BAY 439006 (Ki = 38 nM for mutant B-Raf, 6 nM for c-Raf). It displays potent selectivity over 46 other kinases. Unlike the multi-kinase inhibitor BAY43-9006, this chemical stabilizes the oncogenic B-Raf kinase domain in an active configuration. In Colo205, HT29, A375P, SKMEL28, and MALME-3M cells expressing oncogenic B-RafV600E, this compound treatment potently inhibits ERK phosphorylation with EC50 of 28 nM, 58 nM, 290 nM, 58 nM, and 190 nM, respectively, and consistently, inhibits the proliferation with EC50 of 0.1 μM, 0.87 μM, 0.37 μM, 0.12 μM, and 0.15 μM, respectively. It decreases anchorage-independent growth of melanoma cell lines in a BRAF mutant-selective manner. This chemical displays high affinity for B-Raf with Kd of 0.3 nM. Most of the melanoma cell lines that harbour the BRAF V600E mutation and lack CDK4 mutations (451Lu, WM35, and WM983) are highly sensitive to this compound with IC50 of <1 μM. Increased levels of cyclin D1 resulting from genomic amplification mediate this compound resistance in B-Raf V600E-mutated melanomas.
In Vivo Administration of SB590885 potently decreases tumorigenesis in murine xenografts established from mutant B-Raf-expressing A375P melanoma cells, and modestly inhibits tumour growth.
Features Displays significant selectivity for B-Raf over c-Raf.
