  Direct modification of tripeptides using photoinduced decarboxylative radical reactions

  摘要：

  In order to explore the applicability of photoinduced electron transfer (PET) promoted decarboxylative reactions to the direct modification of peptides, a study was performed to assess the influence of amino acid side chains on photoreactions of N-terminal protected tripeptides. Photoinduced decarboxylation reactions of tripeptides, which are composed of central amino acids that possess alkyl, phenyl, thioether, hydroxy, and amide containing side chains, in the presence or absence of acrylonitrile and a thiol were found to proceed smoothly to give the corresponding radical addition, H-abstraction, and substitution products. Although photoreactions of tripeptides containing central amino acids with phenol and indole (Tyr and Trp) moieties do not take place efficiently, appropriate protection of these groups enables the substrates to undergo smooth photoinduced decarboxylative reactions.

  A series of peptidyl vinyl ester derivatives bearing three different P1 substitutions as potential proteasome inhibitors were studied. The target molecules were designed based on CADD (computer aided drug design) protocol and synthesized. Their activities toward proteasome and four human cancer cell lines (including hepatoma cell line (Bel-7402), myeloid leukemic cell line (HL-60), gastric cancer cell
