生物活性 | Cabozantinib hydrochloride is a potent and orally active inhibitor ofVEGFR2andMET, withIC50values of 0.035 and 1.3 nM, respectively. Cabozantinib hydrochloride displays strong inhibition ofKIT,RET,AXL,TIE2, andFLT3(IC50=4.6, 5.2, 7, 14.3, and 11.3 nM, respectively). Cabozantinib hydrochloride shows antiangiogenic activity. Cabozantinib hydrochloride disrupts tumor vasculature and promotes tumor and endothelial cellapoptosis[1]. |
体外研究 (In Vitro) | Cabozantinib hydrochloride inhibits phosphorylation of MET and VEGFR2, as well as KIT, FLT3, and AXL with IC50values of 7.8, 1.9, 5.0, 7.5, and 42 μM, respectively[1]. Cabozantinib hydrochloride (4.6 nM) inhibits tubule formation with no evidence of cytotoxicity, with IC50values of 6.7, 5.1, 4.1, 7.7, and 4.7 nM in HMVEC, MDA-MB-231, A431, HT1080, and B16F10 cells, respectively[1]. Cabozantinib hydrochloride (0-370 nM, 24 h) inhibits cellular migration and invasion[1]. Cabozantinib hydrochloride (48 h) inhibits tumor cell proliferation in a variety of tumor types[1].
