  Structure–activity study of epi-gallocatechin gallate (EGCG) analogs as proteasome inhibitors

  摘要：

  The structure-activity relationship of a number of synthetic green tea polyphenol analogs involving modifications of A ring and B ring of epi-gallocatechin gallate (EGCG) as proteasome inhibitors has been examined. It was found that in B ring, a decrease in the number of OH groups led to decreased potency. Introduction of a hydrophobic benzyl group into the 8 position of A ring did not significantly affect the proteasome-inhibitory potency. (c) 2005 Elsevier Ltd. All rights reserved.
