Axitinib

Mechanism of action:
Axitinib is a small-molecule tyrosine kinase inhibitor. It selectively inhibits the tyrosine kinase activity of the vascular endothelial growth factor receptor (VEGFR) family, including VEGFR-1, VEGFR-2, and VEGFR-3. By blocking VEGF signaling, axitinib suppresses tumor-associated angiogenesis and blood supply signaling, thereby inhibiting tumor cell growth.
