  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.

  (−)-EGCG, the most abundant catechin, was found to be chemopreventive and anticancer agent. However, (−)-EGCG has at least one limitation: it gives poor bioavailability. This invention provides compounds of generally formulae below, wherein R 11 , R 12 , R 13 , R 21 , R 22 , R 2 , R 3 , and R 4 are each independently selected from the group consisting of —H, and C 1 to C 10 acyloxyl group; and R 5 is selected from the group consisting of —H, C 1 -C 10 -alkyl, C 2 -C 10 -alkenyl, C 2 -C 10 -alkynyl, C 3 -C 7 -cycloalkyl, phenyl, benzyl and C 3 -C 7 -cycloalkenyl, whereas each of the last mentioned 7 groups can be substituted with any combination of one to six halogen atoms; at least one of R 11 , R 12 , R 13 , R 21 , R 22 , R 2 , R 3 and R 4 is —H, which were found to be more potent than their non-protected counterparts, which can be used as proteasome inhibitors to reduce tumor cell growth.

  (-)-EGCG是最丰富的儿茶素之一，被发现具有化学预防和抗癌作用。然而，(-)-EGCG至少存在一个限制：其生物利用度较低。本发明提供了一般化学式如下的化合物，其中R11、R12、R13、R21、R22、R2、R3和R4各自独立地选择自-H和C1到C10酰氧基的群组成；而R5选择自-H、C1-C10烷基、C2-C10烯基、C2-C10炔基、C3-C7环烷基、苯基、苄基和C3-C7环烯基，而最后提到的7个基团中的每一个都可以用任意组合的1到6个卤素原子取代；其中至少有一个是R11、R12、R13、R21、R22、R2、R3和R4中的-H，这些化合物比其非保护的对应物更有效，可用作蛋白酶体抑制剂来减少肿瘤细胞生长。
