capping group, corresponding to cyclic tetrapeptide framework in case of chlamydocin is supposed to interact with the surface of HDAC molecule. Various changes in amino acid residues in chlamydocin may afford specific inhibitors toward HDAC paralogs. To find out specific inhibitors, we focused on benzene ring of l-Phe in chlamydocin framework to shift to various parts of cyclic tetrapeptide. We prepared

Inhibitors of histone deacetylases (HDACs) are a promising class of anticancer agents that effect gene regulation. To know the interaction of aliphatic cap groups with HDACs, cyclic tetrapeptide and bicyclic peptide disulfide hybrids were synthesized without aromatic ring in their macrocyclic framework. Benzene ring Of L-Phe in chlamydocin was replaced with several aliphatic amino acids and also a fused bicyclic tetrapeptide was synthesized by ring closing metathesis using Grubb's first generation catalyst. The inhibitory activities of the cyclic peptides against historic deacetylase enzymes were evaluated, which demonstrated most of them are interesting candidates as anticancer agents.
