Biological Activity

RAF265 (CHIR-265) is a novel, orally bioavailable dual inhibitor of RAF kinase and VEGFR2. RAF265 significantly enhanced TRAIL sensitivity in NCI-H727 and CM insulinoma cells by blocking Raf-MEK-Erk signalling. RAF265 strongly decreased Bcl-2 levels in those cell lines susceptible to its TRAIL-sensitizing action. RAF265 impaired in vitro differentiation of PBMCs to OCs induced by receptor activator of NF-kB ligand (RANKL) and M-CSF (IC(50) ≈ 160 nM). In parallel, RAF265 exerted a potent inhibition of OC resorptive capacity (IC(50) ≈ 20 nM). Moreover, RAF265 exhibits reduced pMEK1, reduced proliferation based upon reduced Ki-67, cyclin D1 and polo-like kinase1 levels, and induction of the apoptosis mediator BCL2-like 11. Using Raf-MEK-Erk pathway inhibitors and TRAIL together might offer a novel therapeutic strategy in NET disease.

Protocol
Cell Experiment
Cell lines HCT116, HT29, and MDAMB231 cell lines
Preparation method Cell Viability Assay
The MTT assay and Bliss additivism model were used to assess the effect of the combination on cell viability. In each well of a 96-well plate, 1 × 104 cells were grown in 200 μL of medium. After 24 h, RAD001, RAF265, or the combination was added to achieve a final concentration of 0.1 to 10 nmol/L and 0.1 to 10 μmol/L, respectively. After 48 h of treatment, 20 μL of 5 mg mL−1 MTT (Organics Research, Inc.) solution in PBS was added to each well. After 4 h, supernatant was removed and formazan crystals were discarded in 200 μL of DMSO. Absorbance was then measured at 595 nm using an absorbance plate reader (Bio-Rad Microplate Reader). Data are expressed as the percentage of viable cells in treated relative to nontreated conditions.

Animal models mice bearing HCT116, A549 or MDAMB231 xenografts
Formulation DMSO/PBS
Dosages 12 mg/kg daily over 14 d (6 d on, 2 d off, 6 d on)
Administration orally
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
