MedKoo CAT#: 201934

CAS#: 453562-69-1 (Motesanib); 857876-30-3 (Motesanib diphosphate)

Description: Motesanib, also known as AMG-706, is the orally bioavailable multiple-receptor tyrosine kinase inhibitor with potential antineoplastic activity. Motesanib selectively targets and inhibits vascular endothelial growth factor (VEGFR), platelet-derived growth factor (PDGFR), kit, and Ret receptors, thereby inhibiting angiogenesis and cellular proliferation.

Additional Information

Motesanib is an orally-administered small molecule antagonist of vascular endothelial growth factor receptors 1, 2 and 3 (“VEGFR1-3”), platelet-derived growth factor receptor (“PDGFR”) and stem cell factor receptor (“c-kit”). It is being investigated as a cancer treatment. We are developing this product in collaboration with Takeda.
