Abstract :

Our interest in the design, synthesis and biological investigations of peptides is, progressively, reported [1-5]. Herein, the search for potent biological agents presents an updated area of the organo-biochemical literature. Herein, Nα-1, 3-benzenedicarbonyl linear peptide candidates, has the structure: Nα-1, 3-benzenedicarbonyl-bis-(Amino acids)-X, general structure A. On the other hand, Nα-benzendicarbonyl bridged cyclo-pentapeptides, having the structure: Cyclo-[Nα- benzendicarbonyl- bis-(dipeptide)- L-Lys]-Y, general structure B. Variable synthetic coupling methods, in solution, as well as experimental reaction conditions, were experimented. The candidates were, chromatographically purified and spectroscopically characterized. A preliminary cytotoxicity evaluation, against eight human cancer cell lines, was realized (National Cancer Institute, Egypt). The detailed cytotoxic and hepato-toxic results, compared to those of five common anticancer drugs and their biochemical assays, particularly, as histone deacetylase inhibitors are currently in progress. Structure-activity relationships were outlined and suggested prospective were proposed.
