Design and synthesis of new 3-((7-chloroquinolin-4-yl)amino)thiazolidin-4-one analogs as Mycobacterium tuberculosis DNA gyrase inhibitors

Abstract

Background: Tuberculosis is evidently a major health threat among human populations worldwide. The current study presents the synthesis of new 3-((7-chloroquinolin-4-yl)amino)thiazolidin-4-one analogs (4a-o) as potential Mycobacterium tuberculosis DNA gyrase inhibitors. DNA gyrase regulates DNA topology in MTB and has been a target of choice for antibacterial therapy. With this in mind, the synthesized derivatives (4a-o) were subjected to in vitro antitubercular evaluation by the MABA method and were tested for MTB DNA gyrase inhibition by supercoiling assay.
