Abstract

ABSTRACT Hypocrellins A and B were evaluated for in vitro antimicrobial and antileishmanial activities. Hypocrellin A exhibited promising activity against Candida albicans and moderate activity against Staphylococcus aureus , methicillin-resistant S. aureus , Pseudomonas aeruginosa , and Mycobacterium intracellulare . Hypocrellin B showed weak antimicrobial activities. Hypocrellin A exhibited potent antileishmanial activity, while hypocrellin B was only moderately active. These results of promising antifungal and antileishmanial activity of hypocrellin A may be useful for further structure-activity relationship and in vivo studies.
