RAF-709

Research use only, not for human use.

A novel potent, selective, and orally bioavailable RAF inhibitor with biochemical IC50 of 0.4 nM and 0.5 nM for BRAF and CRAF, respectively.

A novel potent, selective, and orally bioavailable RAF inhibitor with biochemical IC50 of 0.4 nM and 0.5 nM for BRAF and CRAF, respectively; suppresses pERK (EC50=0.02-0.1 uM), stabilizes BRAF?CRAF dimers(EC50=0.8 uM) inhibits proliferation (EC50=0.95 uM) in KRAS mutant tumor cell lines (Calu6); shows effectivity in a KRAS mutant xenograft model.

RAF709 stabilizes BRAF-CRAF dimers with an EC50 of 0.8 μM. In cellular assays, the dose-response of pMEK and pERK are measured in Calu-6 cells with EC50=0.02 and 0.1 μM with minimal paradoxical activation and inhibition of proliferation with EC50=0.95 μM.

RAF709 proves to be soluble, kinase selective, and efficacious in a KRAS mutant xenograft model. RAF709 shows dose-proportional increases in plasma exposure and a corresponding dosedependent inhibition of pERK in Calu-6 tumors. Treatment with RAF709 results in dose-dependent antitumor activity with 10 mg/kg being subefficacious (%T/C=92%), 30 mg/kg results in measurable antitumor activity (%T/C=46%), and 200 mg/kg results in mean tumor regression of 92%, while the same high dose is not efficacious in the PC3, KRAS WT model.
