Tivozanib hydrochloride hydrate is the hydrate hydrochloride form of Tivozanib (HY-10977). Tivozanib hydrochloride hydrate is a selective, orally active inhibitor for vascular endothelial growth factor receptor (VEGFR)-1, 2 3, with IC50s of 30, 6.5 and 15 nM, respectively. Tivozanib hydrochloride hydrate exhibits antitumor efficacy[1].
Tivozanib hydrochloride hydrate inhibits the phosphorylation of VEGFR-1, VEGFR-2, and VEGFR-3, with IC50s of 0.16-0.24 nM[1].
Tivozanib hydrochloride hydrate (0-100 nM, 24 h) inhibits VEGF-induced proliferation of HUVECs with IC50 of 0.67 nM, and migration of HUVECs in dose-dependent manner[1].
Tivozanib hydrochloride hydrate (0-300 nM, 1 h) selectively inhibits the VEGF-stimulated phosphorylation of MAPKs in endothelial cells ligand-dependently, with IC50s of 0.13 and 0.18 nM for ERK1 and ERK2, respectively[1].
Tivozanib hydrochloride hydrate (0.04-1 mg/kg, po for 14 days) exhibits antitumor efficacy against breast, colon, hepatic, lung, ovarian, pancreatic, and prostate cancer in athymic mice model[1].
Tivozanib hydrochloride hydrate (0.2-1 mg/kg, po for 21 days) reversibly suppresses vascular permeability and angiogenesis in Calu-6 tumor bearing rats model[1].
