Abstract: Filamenting temperature sensitive protein Z (FtsZ) is an essential bacterial cell division protein and a promising target for the development of new antibacterial therapeutics. As a part of our ongoing SAR studies on 2,5,6-trisubstituted benzimidazoles as antitubercular agents targeting Mtb-FtsZ, a new library of compounds with modifications at the 2 position was designed, synthesized and evaluated for their activity against Mtb-H37Rv. This new library of trisubstituted benzimidazoles exhibited MIC values in the range of 0.004-50 microg mL-1. Compounds 6b, 6c, 20f and 20g showed excellent growth inhibitory activities ranging from 0.004-0.08 microg mL-1. This SAR study has led to the discovery of a remarkably potent compound 20g (MIC 0.0039 microg mL-1; normalized MIC 0.015 microg mL-1). Our 3DQSAR model predicted 20g as the most potent compound in the library.
