Abstract
Aim: We aim to develop new anti-leishmanial agents against Leishmania major and Leishmania tropica.Materials & methods: A total of23 thiourea derivatives of (±)-aminoglutethimide were synthesized and evaluated for in vitro activity against promastigotes of L. major and L. tropica.Results & conclusion: The N-benzoyl analogue 7p was found potent (IC50=12.7μM) against L. major and nontoxic to normal cells. The docking studies, indicates that these inhibitors may target folate and glycolytic pathways of the parasite. The N-hexyl compound 7v was found strongly active against both species, and lacked cytotoxicity against normal cells, whereas compound 7r, with a 3,5-bis-(tri-fluoro-methyl)phenyl unit, was active against Leishmania, but was cytotoxic in nature. Compound 7v was thus identified as a hit for further studies.
