Abstract

A series of pyrrole-thiazolidinone hybrids was designed, synthesized and evaluated for activities against ESKAP bacteria panel and mycobacterial pathogens. From the series, compound 9d showed prominent activity against S. aureus (MIC = 0.5 μg/mL) and compound 9k showed the most promising activity against M. tuberculosis H37Rv (MIC = 0.5 μg/mL). Potent derivatives were found to be non-toxic when tested against Vero cells. Compound 9d upon evaluation in vitro against several MRSA and VRSA strains produced activity comparable or better than standard drugs. In the anti-biofilm assay, 9d reduced S. aureus biofilm by >11% at 10x MIC. The dual inhibitory effect exhibited by pyrrole-thiazolidinone hybrids confirms their potential as new class of promising anti-infective agents.
