AT-533

AT-533 is a potent inhibitor of heat shock protein 90 (Hsp90) and herpes simplex virus (HSV), exhibiting strong antitumor and antiviral activities. It suppresses tumor growth and angiogenesis by disrupting the HIF-1α/VEGF/VEGFR-2 signaling axis, a critical pathway in tumor vascularization and progression. Additionally, AT-533 inhibits key downstream signaling cascades, including Akt/mTOR/p70S6K, ERK1/2, and FAK pathways. In endothelial cells, specifically human umbilical vein endothelial cells (HUVECs), AT-533 effectively inhibits tube formation, cell migration, and invasion, highlighting its anti-angiogenic properties. These combined effects position AT-533 as a promising candidate for cancer therapy and angiogenesis-related disease research.
