UCM05（Cat No.:I011200）is a synthetic small-molecule inhibitor of Heat Shock Protein 90 (Hsp90), a molecular chaperone involved in stabilizing and activating numerous client proteins essential for cancer cell growth and survival. By disrupting Hsp90 function, UCM05 promotes the degradation of oncogenic proteins, impairing multiple signaling pathways in tumor cells. It has demonstrated antiproliferative and pro-apoptotic effects in various cancer models. UCM05 is a valuable tool for studying proteostasis, stress response mechanisms, and the development of targeted cancer therapies, particularly in malignancies reliant on Hsp90-dependent signaling networks.
