摘要

Two thioacetate tails were introduced to the chlamydocin- and CHAP31-related cyclic tetrapeptides. An intramolecular disulfide bridge could be formed in the CHAP31-related cyclic peptides. Both the thioacetate-tailed and disulfide-bridged peptides were potent histone deacetylase inhibitors in the presence of sulfhydryl compound. Potent p21 promoter inducing activity was also observed in vivo.Copyright © 2012. Published by Elsevier Ltd.
