    摘要:
    Synthesis of procyanidin B2 and B3 gallate derivatives, 3-O-gallate, 3 ''-O-gallate, and 3,3 ''-di-O-gallate, were synthesized using equimolar condensation mediated by Yb(OTf)(3). Synthesized compounds showed significant antitumor effects against human prostate PC-3 cell lines. Their activities were weaker than well-known EGCG and prodelphinidin B3. (C) 2013 Elsevier Ltd.

  • Systematic synthesis of galloyl-substituted procyanidin B1 and B2, and their ability of DPPH radical scavenging activity and inhibitory activity of DNA polymerases
    作者:Akiko Saito、Yoshiyuki Mizushina、Hiroshi Ikawa、Hiromi Yoshida、Yuki Doi、Akira Tanaka、Noriyuki Nakajima

    日期:2005.4
    Six galloyl-substituted procyanidin B1 and B2, 3-O-gallate, 3"-O-gallate, and 3,3"-di-O-gallate, were systematically synthesized with the condensation method using TMSOTf as a catalyst. Their ability of DPPH radical scavenging activity and DNA polymerase inhibitory activity were also investigated. The results indicated that the galloyl group of these compounds is very important for both activities. 3,3"-Di-O-gallate dimers acted as strong inhibitor against DNA polymerase alpha and beta, whereas the desgalloyl and monogalloyl compounds did not exhibit any appreciable inhibitory activity against the DNA polymerase beta.
