exerting their activity by inhibiting the subunit A of DNA gyrase. Recently, pyrimido-[1,6-a]benzimidazoles 2 were found to be a new class of inhibitors of this enzyme. As, in 1, replacement of C(8) by the N-atom was shown beneficial for the biological properties, a synthesis of the corresponding aza analogues of 2 has been carried out. The synthesis, DNA gyrase inhibitory activity, and in vitro antibacterial
取代的4-氧代喹啉-3-(1a)和4-氧代-1,8-萘啶-3-(1b)羧酸是临床上有用的抗菌剂,可通过抑制DNA促旋酶的亚基发挥作用。最近,发现嘧啶基-[1,6- a ]苯并咪唑2是该酶的新型抑制剂。由于在图1中,显示出由N原子取代C(8)对生物学特性是有益的,因此已经进行了相应的氮杂类似物2的合成。报告了目标化合物16-19的合成,DNA促旋酶抑制活性和体外抗菌活性。
