Abstract: Novel 3?-hydroxy-?5-steroid analogs possessing a contracted cyclopentane B-ring provide good inhibitory activity against Mycobacterium tuberculosis. The 5(6?7)abeo-sterol nucleus present in compounds of the invention represents a novel scaffold for the development of new antitubercular agents.
