Synthesis and Biological Evaluation of Stilbene Analogues as Hsp90 C-Terminal Inhibitors

摘要

The design, synthesis, and biological evaluation of stilbene-based novobiocin analogues is reported. Replacement of the biaryl amide side chain with a triazole side chain produced compounds that exhibited good antiproliferative activities. Heat shock protein 90 (Hsp90) inhibition was observed when N-methylpiperidine was replaced with acyclic tertiary amines on the stilbene analogues that also contain a triazole-derived side chain. These studies revealed that approximate to 24 angstrom is the optimal length for compounds that exhibit good antiproliferative activity as a result of Hsp90 inhibition.
