Tivozanib is an inhibitor of tyrosine kinase with IC50 value of 160 pmol/L against VEGFR-2 [1].
Tivozanib is a quinoline-urea derivative. As a 2nd generation TKI, it has picomolar potency against VEGFR-1, -2 and -3, and minimal c-kit inhibition. Among this, Tivozanib has demonstrated a VEGFR-2 potency 2 orders of magnitude greater than sunitinib, sorafenib or pazopanib and a lower relative extent of off-target inhibition [1]. Tivozanib also shows to inhibit phosphorylation of the kinases PDGFRß and C-KIT at nanomolar level in cellular assays [2].
Tivozanib has shown antitumor activity in RCC xenograft models in addition to several other solid tumor models leading to its evaluation in clinical testing. The safety and efficacy of Tivozanib has been evaluated in several Phase I and Phase II trials. To compare the front-line use of tivozanib to sorafenib, a pivotal randomized Phase III trial has also been reported [3].

Cell experiment [1]: | |
Cell lines |
Human ovarian carcinoma cell lines, including A2780CP, OVCAR3 and SKOV3. |
Preparation method |
Soluble in DMSO >22.8mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition |
10μm, 48h |
Applications |
Combination of tivozanib with the EGFR(Epidermal Growth Factor Receptor)-directed therapies displayed synergistic activity on cell growth inhibition and induction of apoptosis, suggesting that anti-VEGFR(vascular endothelial growth factor receptor) -targeted approaches induced sensitisation to the EGFR-directed therapies. |
Clinical experiment [2]: | |
Diseases models |
Patients with renal cell carcinoma(RCC) |
Dosage form |
1.5 mg OD for 3 weeks, oral administration |
Application |
Tivozanib exhibit an inhibitory profile with high sensitivity for inhibition of VEGFR family members. Patients receiving tivozanib had a PFS(Progression free survival) of 12.7 months – the best PFS reported in a phase III trial with mRCC. |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
