Bactericidal Activities of the Pyrrole Derivative BM212 against Multidrug-Resistant and Intramacrophagic <i>Mycobacterium tuberculosis</i> Strains

Abstract

The pyrrole derivative BM212 [1, 5-diaryl-2-methyl-3-(4-methylpiperazin-1-yl)methyl-pyrrole] was shown to possess strong inhibitory activity against both Mycobacterium tuberculosis and some nontuberculosis mycobacteria. BM212 was inhibitory to drug-resistant mycobacteria and also exerted bactericidal activity against intracellular bacilli residing in the U937 human histiocytic lymphoma cell line.
