Description

Sorafenib (Bay 43-9006) is a potent and orally active Raf inhibitor with IC50s of 6 nM and 20 nM for Raf-1 and B-Raf, respectively. Sorafenib is a multikinase inhibitor with IC50s of 90 nM, 15 nM, 20 nM, 57 nM and 58 nM for VEGFR2, VEGFR3, PDGFRβ, FLT3 and c-Kit, respectively. Sorafenib induces autophagy and apoptosis. Sorafenib has anti-tumor activity. Sorafenib is a ferroptosis activator.

In Vitro Activity

Sorafenib (BAY 43-9006) also inhibits BRAFwt (IC50=22 nM), BRAFV599E (IC50=38 nM), VEGFR-2 (IC50=90 nM), VEGFR-3 (IC50=20 nM), PDGFR-β (IC50=57 nM), c-KIT (IC50=68 nM), and Flt3 (IC50=58 nM) in biochemical assays. In MDA-MB-231 breast cancer cells, Sorafenib completely blocks activation of the MAPK pathway. Cells are preincubated with Sorafenib (0.01 to 3 μM), and dose-dependent inhibition of basal MEK 1/2 and ERK 1/2 phosphorylation (IC50, 40 and 100 nM, respectively).

In Vivo Activity

Sorafenib demonstrates broad oral antitumor efficacy in panel of human tumor xenograft models. Sorafenib is given orally at 7.5 to 60 mg/kg. There is no lethality and no increase in weight loss in any treated group relative to the corresponding control group. Daily oral administration of Sorafenib (30 to 60 mg/kg) produces complete tumor stasis during treatment in five of the six models. The survival rate is 73.3 % in Diethyl nitrosamine (DENA) group and 83.3 % in Sorafenib group compared to 100 % in the normal control group. DENA group shows a significant increase in liver index (1.51-fold increase, p<0.05) compared to normal control group, while treatment with Sorafenib shows significant decrease (p<0.05) in liver index when compared to DENA group. The liver index in Sorafenib group significantly decreases to lower than its value in the normal control.
