Abstract

Quaternized triflupromazine derivatives (QTDs) must possess benzyl groups attached to the quaternary nitrogen in order to have significant antitubercular potency. Replacing the quaternary amine with a triazole abolishes antitubercular activity. A modest halogen substitution effect exists, with the 4-bromophenyl QTD 3 having the best selectivity index (>21). All N-benzyl QTDs 1-4 similarly inhibit non-replicating, persistent Mycobacterium tuberculosis with MIC<8 μM, and compounds 1-3 were all nontoxic to mammalian cells in vitro (IC(50)>128 μM).
