Biological Activity

Motesanib diphosphate (AMG 706) is a novel oral inhibitor of VEGF receptors, platelet-derived growth-factor receptor, and KIT. It is used as the phosphate salt motesanib diphosphate. Motesanib Diphosphate significantly inhibits VEGF-induced cellular proliferation of HUVECs with an IC50 of 10 nM, while displaying little effect at bFGF-induced proliferation with an IC50 of >3,000 nM. Motesanib Diphosphate (AMG 706) induces a dose-dependent tumor regression of established A431 xenografts by selectively targeting neovascularization in tumor cells. Motesanib diphosphate (AMG 706) can induce partial responses in patients with advanced or metastatic differentiated thyroid cancer that is progressive.

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.
