Amuvatinib (formerly known as MP470), is a novel receptor tyrosine kinase inhibitor, it has inhibitory effect on prostate cancer in combination with Erlotinib in vitro and in vivo. Amuvaninib (MP470) inhibited RAD51 protein expression and HR. Amuvatinib also inhibits activities of other receptor tyrosine kinases, such as c-Met, Ret oncoprotein, and mutant forms of Flt3, which are frequently dysregulated in variety of tumors. Amuvatinib (MP470) exhibits low microM IC50 in prostate cancer cell lines. When LNCaP were treated with MP470 in combination with Erlotinib, additive effects on both cytotoxicity and induction of apoptosis were observed. Furthermore, the MP470-Erlotinib combination produced 30-65% dose-dependent tumor growth inhibition (TGI) in a LNCaP mouse xenograft model. Amuvatinib (MP470) sensitized cells to IR and MMC, agents that are selectively toxic to HR-deficient cells. Mutant forms of c-Kit are often associated with tumor chemoresistance.

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.

The receptor tyrosine kinase inhibitor amuvatinib (MP470) sensitizes tumor cells to radio- and chemo-therapies in part by inhibiting homologous recombination.
