We have designed and synthesized both the quinoline and naphthalene based molecules influenced by the unique structural make-up of mefloquine and TMC207, respectively. These compounds were evaluated for their anti-mycobacterial activity against drug sensitive Mycobacterium tuberculosis H37Rv in vitro at single-dose concentration (6.25 microg/mL). The compounds 22, 23, 26 and 27 inhibited the growth of M. tuberculosis H37Rv 99%, 90%, 98% and 91% respectively. Minimum inhibitory concentration of compounds 22, 23, 26 and 27 was found to be 6.25 microg/mL. Our molecular modeling and docking studies of designed compounds showed hydrogen bonding with Glu-61, Tyr-64 and Asn-190 amino acid residues at the putative binding site of ATP synthase, these interactions were coherent as shown by Mefloquine and TMC207, where hydrogen bonding was found with Tyr-64 and Glu-61 respectively. SAR analysis indicates importance of hydroxyl group and nature of substituents on piperazinyl-phenyl ring was critical in dictating the biological activity of newly synthesized compounds.

The emergence of drug resistance in infectious microbial strains can be overcome by development of novel drug molecules against unexploited microbial target. The success of Bedaquiline in recent years, as FoF1 ATP synthase inhibitor against XDR and MDR mycobacterium strains, has resulted in further exploration to identify more potent and safe drug molecules against resistant strains. FoF1 ATP synthase is the main energy production enzyme in almost all eukaryotes and prokaryotes. Development of bacterial ATP synthase inhibitors is a safe approach, without causing harm to mammalian cells due to structural difference between bacterial and mammalian ATP synthase target sites. This review emphasizes on providing the structural insights for FoF1 ATP synthase of different prokaryotes and will help in the design of new potent antimicrobial agents with better efficacy. Further, applications of synthetic and natural active antimicrobial ATP synthase inhibitors, reported by different research groups are summarized. Their SAR and mode of actions are also analysed.
