Telatinib (BAY 57-9352) is an orally available, small-molecule inhibitor of vascular endothelial growth factor receptors 2 and 3 (VEGFR-2/-3) and platelet-derived growth factor receptor β tyrosine kinases. Telatinib inhibits VEGFR2 autophosphorylation in a whole-cell assay with an IC50 of 19 nM. Telatinib (BAY 57-9352) blocks PDGF-stimulated growth of human aortic smooth muscle cells with an IC50 of 249 nM. Telatinib treatment significantly inhibits tumor growth and metastasis by blocking the VEGFR signaling and subsequently tumor angiogenesis. Administration of Telatinib as a single agent exhibits a potent anti-tumor activity in multiple human tumor xenograft models including MDA-MB-231 breast cancer, DLD-1 colon cancer and H460 non-small cell lung cancer.

|Animal A 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.
