Guillon,Dumoulin,Dallemagne,Reynolds,Rault

, p. 33 - 38 (2007/10/03)

During the course of our work on the synthesis and screening of new drugs for tuberculosis, we have identified three new phenylpyrrolo[1,2-a]quinoxalinylpyrrole carboxylic acid derivatives which inhibited in-vitro Mycobacterium tuberculosis H37Rv; 97-98% inhibition at 12.5 μg mL-1.
