Targeting the Heat Shock Protein 90 Dimer with Dimeric Inhibitors
摘要:
The design, synthesis, and biological evaluation of conformationally constrained coumermycin Al analogues are reported. Compounds were evaluated against both breast cancer (SKBr3 and MCF7) and prostate cancer (PC3 mm2, A549, and HT29) cell lines. Non-noviosylated coumermycin Al analogues that manifest potent antiproliferative activity resulting from Hsp90 inhibition are provided, wherein replacement of the stereochemically complex noviose sugar with readily available piperidine rings resulted in similar to 100 fold increase in antiproliferative activities as compared to coumermycin Al, producing small molecule Hsp90 inhibitors that exhibit nanomolar activities.
An inhibitor of heat shock protein 90 (HSP90) can include a coumermycin A1 analog having a structure that inhibits HSP90 greater than coumermycin A1. That is, the coumermycin A1 analog is not coumermycin A1. The coumermycin A1 analog can have an antiproliferative biological activity, which can be superior to coumermycin A1. The activity can include the coumermycin A1 analog inhibiting a C-terminus of HSP90.
