CAS: 1799802-29-1

SST0116CL1 is an HSP90 inhibitor (IC50: 0.21 μM) that targets the ATP-binding pocket of Hsp90, disrupting its chaperone function and leading to the degradation of client proteins (EGFR, CDK4, and AKT). It induces the degradation of Her2 in BT-474 cells (IC50: 0.2 μM) and exhibits antiproliferative activity, inhibiting tumor growth.
