Abstract

Eight sansalvamide A peptide analogues with 4′-fluoride, 4′-chloride, 4′-bromide, 4′-iodide, and 4′-methoxyphenylalanine moieties were synthesized. The effect of these para-substitutions of sansalvamide A peptide on their cytotoxicity was evaluated using HCT-116, MDA-MB-231, HT-29, HCT-15, K562, HeLa, and A549 cell lines. The 4′-methoxyphenylalanine analog of sansalvamide A peptide was found to be a promising antitumor agent.
