CAY10747 is an inhibitor of the protein-protein interaction between heat shock protein 90 (Hsp90) and cell division cycle 37 (Cdc37) and a derivative of celastrol .1It decreases protein levels of the Hsp90-Cdc37 complex and the Hsp90-Cdc37 clients phosphorylated Akt and Cdk4 in A549 cells when used at a concentration of 5 μM. CAY10747 inhibits proliferation of A549, MCF-7, HOS, and HepG2 cells (IC50s = 0.41, 0.64, 0.9, and 0.94 μM, respectively) and induces apoptosis in A549 cells. 1.Li, N., Xu, M., Wang, B., et al.Discovery of novel celastrol derivatives as Hsp90-Cdc37 interaction disruptors with antitumor activityJ.

Aminohexylgeldanamycin (AHGDM), a derivative of Geldanamycin, is a highly effective inhibitor of HSP90. It exhibits considerable antiangiogenic and antitumor properties[1].
DP-1, a Ganetespib degradation product, represents a fragment derived from SDC-TRAP-0063. Ganetespib itself functions as an inhibitor of heat shock protein 90 (HSP90), exhibiting notable anti-tumor properties.
MAO A HSP90-IN-1 (4-b) 是一种针对MAO A和HSP90的双重抑制剂,展现在恶性胶质瘤GL26细胞上的IC50为1.77 μM,针对HSP90α的IC50为0.019 μM。该化合物能够通过抑制MAO A活性和HSP90结合,以及降低HER2和phospho-Akt表达,进而抗击恶性胶质瘤(GMB)。同时,MAO A HSP90-IN-1 (4-b)可减少PD-L1的表达,从而降低T细胞活化的抑制,有望用来抑制肿瘤的免疫逃逸。该化合物适用于脑肿瘤相关疾病研究。
