  Synthesis and Structure–Activity Relationships of EGCG Analogues, a Recently Identified Hsp90 Inhibitor

  摘要：

  Epigallocatechin-3-gallate (EGCG), the principal polyphenol isolated from green tea, was recently shown to inhibit Hsp90; however, structure activity relationships for this natural product have not yet been produced. Herein, we report the synthesis and biological evaluation of EGCG analogues to establish structure activity relationships between EGCG and Hsp90. All four rings as well as the linker connecting the C- and the D-rings were systematically investigated, which led to the discovery of compounds that inhibit Hs90 and display improvement in efficacy over EGCG. Antiproliferative activity of all the analogues was determined against MCF-7 and SKBr3 cell lines and Hsp90 inhibitory activity of the four most potent analogues was further evaluated by Western blot analyses and degradation of Hsp90-dependent client proteins. The prenyl-substituted aryl ester of 3,5-dihydroxychroman-3-ol ring system was identified as a novel scaffold that exhibits Hsp90 inhibitory activity.

  Systematic simplification of the molecular structures of epicatechin gallate and epigallocatechin gallate to determine the minimum structural characteristics necessary for HIV-1 reverse transcriptase inhibition in vitro resulted in several compounds that strongly inhibited the native as well as the A17 double mutant (KI03N Y181C) enzyme, which is normally insensitive to most known nonnucleoside inhibitors.
