Abstract
Malaria is the most common of the parasitic diseases in tropical and subtropical regions. Adverse side effects of anti-malarial drugs have precluded them as a potential clinical drug. In this study, novel derivatives of N-acetyl-l-leucyl-l-leucyl-l-norleucinal (ALLN) based on a variety of dipeptidyl α,β-unsaturated amides containing lysine as a part were synthesized and evaluated. Lower toxicity was achieved by reducing or eliminating the tendency of forming chemically reactive and toxic intermediates and metabolites. The synthesized compounds were evaluated for anti-malarial efficacy against Plasmodium falciparum and cytotoxicity in human epitheloid carcinoma cervix (HeLa cells) by estimating the therapeutic index (TI). N-Methyl amide with Nâ²-Boc protection among them exhibited strong anti-malarial activity and N-methyl amide with Nâ²-m-methylbenzyl amide showed excellent anti-malarial activity with much lower toxicity than the ALLN. Therefore, the two chemicals, as well as the underlying design rationale, could be useful in the discovery and development of new anti-malarial drugs.
