4-dione was determined by X-ray diffraction. The prepared derivatives of desfluoroisothiazolopyridones exhibited (a) antibacterial activity against Gram-negative and Gram-positive organisms, (b) inhibitory activities against DNA gyrase and topoisomerase IV, and (c) no inhibitory activity against human topoisomerase II.
我们报告了异噻唑并吡啶酮的第一代衍生物的合成及其作为抗菌剂的体外评价。使用七个合成转化序列,制备了这些化合物,它们包含一个新的杂环核,该杂环核由与噻唑啉-4-酮(在喹啉嗪-4-酮的C-2和C-3处)融合的异噻唑酮组成。通过X射线衍射测定7-氯-9-乙基-1-硫-2,4a-二氮杂环戊[b]萘-3,4-二酮的固态结构。所制备的去氟异噻唑并吡啶酮的衍生物表现出(a)对革兰氏阴性和革兰氏阳性生物的抗菌活性,(b)对DNA促旋酶和拓扑异构酶IV的抑制活性,和(c)对人拓扑异构酶II的抑制活性。
