新型喹诺酮唑类化合物的设计合成及其抗菌作用研究
发布时间:2022-01-04 16:09
喹诺酮是一类重要的以DNA回旋酶和拓扑异构酶为靶点的合成类抗菌药物。其强的抗菌能力、广的抗菌谱、不良反应小以及药代动力学性质好等优点吸引着众多的科学工作者致力于喹诺酮结构药物的研发,相继开发出四代喹诺酮抗菌药物并广泛应用于临床,在治疗呼吸道感染、前列腺炎、慢性支气管炎以及泌尿系统感染等细菌性感染疾病发挥着重要作用,是迄今为止最重要的合成类抗感染药物。大量文献和临床结果表明基于喹诺酮结构的修饰是研发新型、高效、抗耐药性强抗菌药的高效途径之一。此外,唑类化合物如三唑、咪唑、噻唑等含氮芳杂环以其独特的结构易与生物体内多种酶和受体等作用靶点发生相互作用,在药物开发中发挥着重要的作用,相关工作众多,且已取得丰硕的研究成果。然而,随着近些年来抗生素、喹诺酮类抗感染药物在临床上的广泛使用甚至滥用导致全球性的耐药菌株频发,严重危及人类健康,因此新型抗耐药性的抗菌药物的研发迫在眉睫。鉴于此,本文基于喹诺酮类化合物在国内外抗菌领域的研发现状与本课题组有关喹诺酮和唑类化合物的前期工作,设计合成了一系列新型的喹诺酮唑类抗菌化合物,探索了目标化合物的制备方法与条件,并对其体外抗菌活性、理化性质以及构效关系的进行...
