Abstract : In an effort to discover new anti-tubercular agents, a series of new diarylpyrrole–oxazolidinone conjugates have been designed and synthesized. The anti-tubercular activity of these new conjugates (4a–n and 5a–d) against Mycobacterium tuberculosis H37Rv and drug resistance strains such as M. tuberculosis RifR and M. tuberculosis XDR are discussed, wherein compound 4i has been found to be the most potent amongst the series. MTT assay was performed on the active conjugates of the series (4b–f, 4i and 5c) against mouse macrophage (J-774) cells to evaluate cytotoxic effects and selective index values. In addition, these conjugates (4a–n and 5a–d) are also tested against a panel of Gram-positive and Gram-negative bacterial strains. The docking studies have been carried out to provide some insight into the mechanism of action for this class of compounds
