Synthesis and in vitro biological evaluation of ring B abeo-sterols as novel inhibitors of Mycobacterium tuberculosis
摘要:
A series of 3b-hydroxy steroid analogues possessing a contracted cyclopentane B-ring were prepared based on the initial activity screening of a recently reported naturally occurring marine 5(6-->7) abeo-sterol against Mycobacterium tuberculosis. All of the novel ring B abeo-sterols synthesized showed good inhibitory activity, whereas none of the starting steroids based on the common 3 beta-hydroxy-Delta(5)-cholestane nucleus, proved to be active. Therefore, the 5(6-->7) abeo-sterol nucleus present in compounds 3, 5, 7, 9, and 11 represents a novel scaffold for the development of new antitubercular agents. (C) 2008 Elsevier Ltd.
