Abstract

Substituted 4-quinolone- (1, A = CH) and 1,8-naphthyrid-4-one- (1, A = N) 3-carboxylic acids are currently the only classes of clinically useful antibacterial agents exerting their activity by inhibiting the subunit A of DNA gyrase. Pyrimido[1,6-alpha]benzimidazoles 11 have been found to be a new class of inhibitors of this enzyme. The design, synthesis, and biological activity of these compounds are reported.
