DNA gyrase and topoisomerase IV are essential bacterial enzymes, and in the fight against bacterial resistance, they are important targets for the development of novel antibacterial drugs. Building from our first generation of 4,5,6,7-tetrahydrobenzo[d]thiazole-based DNA gyrase inhibitors, we designed and prepared an optimized series of analogs that show improved inhibition of DNA gyrase and topoisomerase IV from Staphylococcus aureus and Escherichia coli, with IC50 values in the nanomolar range. Importantly, these inhibitors also show improved antibacterial activity against Gram-pos. strains. The most promising inhibitor, 29, is active against Enterococcus faecalis, Enterococcus faecium and S. aureus wild-type and resistant strains, with min. inhibitory concentrations between 4 and 8 g/mL, which represents good starting point for development of novel antibacterials. The experimental part of the paper was very detailed, including the reaction process of 3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0Formula: C9H8O4)
3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0) belongs to esters. Esters are more polar than ethers but less polar than alcohols. Formula: C9H8O4 They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols.
