摘要
Piperine amide analogs are synthesized by replacement of the piperidine moiety with different types of cyclic amines, including adamantyl and monoterpene-derived fragments. The compounds are screened for activity against Mycobacterium tuberculosis H37Rv. The most potent compounds are the 1-adamantyl and the monoterpene-derived hybrids, which combine nanomolar antimycobacterial activity with low cytotoxicity against human cells. The presence of quaternary carbon atom as main structural requirement for anti-TB activity is pointed out by a QSAR study. The most promising compound is the (+)-isopinocampheylamine-derived amide which is characterized with selectivity index of 1387.8.
