Biological target:

RAF709 is a potent, selective, and efficacious RAF inhibitor with IC50s of 0.4 nM and 0.5 nM for BRAF and CRAF, respectively.

In vitro activity:

In in vitro biochemical assays, RAF709 exhibited potent inhibitory activity targeting BRAF, BRAFV600E, and CRAF with IC50 values ranging between 0.3 to 1.5 nmol/L (Fig. 1). Data obtained from the cocrystal structure of RAF709 in complex with the BRAF kinase domain revealed that the protein adopts an inactive conformation with the DFG out and the αC-helix in, characteristic of a type II inhibitor binding mode. In A375 (BRAFV600E) cells, both dabrafenib and RAF709 showed robust activity inhibiting mutant BRAF monomer–driven ERK activation with IC50s of 5 nmol/L and 44 nmol/L, respectively. In comparison, in HCT116 cells (KRASG13D) pretreated with encorafenib, RAF709 exhibited equipotent activity inhibiting RAF dimer–driven signaling with a pERK IC50 of 79 nmol/L, whereas dabrafenib showed approximately 100-fold higher IC50 of 3 μmol/L. The same experiment was carried out in SK-MEL-30 (NRASQ61K) cells with similar results: RAF709 had an IC50 of 0.139 μmol/L (3.2-fold shift) and dabrafenib had an IC50 of 3.7 μmol/L (>700-fold shift; Supplementary Fig. S2). These data suggest that RAF709 inhibits both RAF monomers and dimers with similar potency.

In vivo activity:

Nude mice bearing Calu-6 xenograft tumors were treated with a single dose of RAF709 across a wide dose range (from 10 to 200 mg/kg). Tumor tissues were then collected at multiple time points postdose to determine pMEK levels. As shown in Fig. 6A, RAF709 treatment led to inhibition of MEK phosphorylation in a dose-dependent manner both in degree and in duration. RAF709 at 100 mg/kg and 200 mg/kg was able to suppress pMEK to greater than 50% for more than 16 hours. In line with pMEK inhibition, RAF709 treatment resulted in dose-dependent antitumor activity starting from 30 mg/kg (Fig. 6B). Treatment with 30 mg/kg of RAF709 led to a 52% T/C, while treatment at 100 and 200 mg/kg resulted in tumor regressions of 47% and 88%, respectively, in line with the more durable pathway inhibition at the two higher dose levels.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
