Tivozanib hydrochloride hydrate is a potent and selective and orally active VEGFR tyrosine kinase inhibitor with IC50是of 0.21, 0.16, 0.24 nM for VEGFR-1, VEGFR-2, VEGFR-3, respectively. Tivozanib hydrochloride hydrate inhibits angiogenesis and vascular permeability in tumor tissues and shows antitumor activity. Tivozanib hydrochloride hydrate has the potential for the research of metastatic renal cell carcinoma (RCC) [1][2][3].

Tivozanib hydrochloride hydrate inhibits the phosphorylation of VEGFR-1, VEGFR-2 and VEGFR-3[2].

Tivozanib hydrochloride hydrate (1 mg/kg; p.o.; 14 days) suppresses the development of CNV lesions and leds to a significant regression of established CNV, reducing the affected areas by 67.7%[4].
