Icapamespib, also known as PU-HZ 151, is a heat shock protein 90 (HSP90) inhibitor. PU-HZ151 showed EC50 of 5 nM in the FP assay as compared to 11 nM for PU-H71 and a logD of 2.37 as compared to 1.21 for PU-H71. PU-HZ151 and radiolabeled PU-HZ151 showed selectivity for epichaperomes over the individual chaperome members. Icapamespib demonstrated the ability to productively engage the target in cells, mice, and humans.

2-Chloroadenosine-5'-O-diphosphate是一种腺苷5'二磷酸（ADP）的衍生物。它在浓度依赖性的方式下，促进了人类富含血小板的血浆中的聚集，并抑制了由前列腺素E2（PGE2）诱导的环磷酸腺苷（cAMP）的产生。2-Chloroadenosine-5'-O-diphosphate引起预收缩的孤立的豚鼠taenia coli条带放松（pD2 = 6.74），降低大鼠的动脉血压。此外，它还抑制了热休克蛋白70（Hsp70）家族成员mortalin的ATP酶活性（人类酶的表观Ki = 45.05 µM）。

CH5015765 is a novel, potent, and selective HSP90 inhibitor. CH5015765 showed high affinity for Hsp90 and antitumor activity in human cancer xenograft mouse models.

Geldanamycin-FITC 是一种格尔达霉素荧光探针，可用于HSP90抑制剂的荧光偏振分析。Geldanamycin-FITC 也可用于细胞表面HSP90的检测。储存方式：避光。

Arimoclomol citrate (BRX-220 citrate) is a heat shock protein (HSP) co-inducer that acts by enhancing Hsp expression and directly impacting protein aggregation, clearance of misfolded assemblies, and the proteasome-ubiquitin system. This compound is known for its ability to protect motor neurons.

HSP90-IN-27(compound 19)是一种有效的HSP90抑制剂，可用于研究癌症。
