antibacterial agents. Natural products have historically been a rich source of both antibiotics and lead compounds for new antibacterial agents. The natural product simocyclinone D8 (SD8) has been reported to inhibit DNA gyrase, a validated antibacterial drug target, by a unique catalytic inhibition mechanism of action. In this work, we have prepared simplified flavone-based analogues inspired by the complex
临床上耐药细菌感染的发生率不断增加,因此需要新的抗菌剂。历来,天然产物一直是新型抗菌剂的抗生素和先导化合物的丰富来源。据报道,天然产物simocyclinone D8(SD8)通过独特的催化抑制作用机制可抑制DNA促旋酶(一种经验证的抗菌药物靶标)。在这项工作中,我们准备了基于复杂的天然产物的简化的基于黄酮的类似物,并评估了其抑制活性和作用机理。尽管这些化合物中的两种确实抑制DNA促旋酶,但它们通过与SD8不同的作用机理(即DNA嵌入)来抑制DNA促旋酶。
