AT-533 is a potent Hsp90 and HSV inhibitor. AT-533 suppresses tumor growth and angiogenesis by blocking the HIF-1α/VEGF/VEGFR-2 signaling pathway. AT-533 also inhibits the activation of the downstream pathways, including Akt/mTOR/p70S6K, Erk1/2 and FAK. AT-533 inhibits the tube formation, cell migration, and invasion of human umbilical vein endothelial cells (HUVECs)[1][2][3].
AT-533 (0-1350 nM; 24 h or 48 h) inhibits 20 ng/mL VEGF-induced tube formation, cell migration, and invasion of HUVECs[1].
AT-533 (2 μM or 75 μM; 24 h) inhibits the HIF-1α/VEGF signaling pathway in hypoxia-induced breast cancer cells, as well as inhibiting Akt/mTOR/p70S6K, Erk1/2, and FAK phosphorylation[1].
AT-533 (10 nM, 50 nM; 48 h) shows anti-angiogenic ability in chorioallantoic membrane (CAM) model[1].
AT-533 (0.5 μM; 2 h, 4 h) decreases TNF-α, IL-1β and IL-6 production in RAW264.7 and BV2 cells induced by HSV-1[2].
AT-533 (10 mg/kg; i.p.; once daily for 21 d) suppresses the expression of the HIF-1α/VEGF signaling pathway-related proteins in MDA-MB-231 breast cancer xenografts tumor model in mouse[1].
AT-533 (1, 2 and 4 mg/kg; i.p.; once daily for 30 d) has no mortality, loss of appetite and body weight, adverse reactions in Sprague-Dawley rats in subacute toxicity test[3].
