HSP90-IN-33

HSP90-IN-33 is a selective Hsp90β inhibitor (Kd 7.3 μM) that induces apoptosis and G0/G1 cell cycle arrest by downregulating ERα, CDK4, and Akt protein levels. This compound is a valuable research tool for studying Hsp90 function in cancer biology and for in vitro investigations of oncogenic signaling pathways.
