  Syntheses of prodelphinidin B3 and C2, and their antitumor activities through cell cycle arrest and caspase-3 activation

  摘要：

  Total synthesis of prodelphinidin B3 and C2 have been accomplished. The key step is Lewis acid-mediated equimolar condensations between a catechin and/or gallocatechin nucleophile and a gallocatechin electrophile. The antitumor effects of synthetic prodelphidin B3 and C2 against PC-3 prostate cancer cell lines have been investigated. Both compounds showed significant antitumor effects. Their activity was almost the same as that of EGCG, a known antitumor agent. (C) 2013 Elsevier Ltd. All rights reserved.

  First synthesis of prodelphinidin trimer (epigallocatechin-gallocatechin-catechin) isolated from Cistus albidus was accomplished from monomeric epigallocatechin electrophile and dimeric gallocatechin-catechin nucleophile. The condensation was worked using AgoTf as a Lewis acid and condensed product was successfully converted into titled compound in good yield. Synthesized compound showed significant growth inhibitory activity against human prostate PC-3 cell lines. Its activity was almost same as prodelphinidin B3.
