Seven-membered heterocyclic [1,2,5]triazepane and [1,2,5]oxadiazepane derivatives were synthesized as candidate structures for application in drug discovery in place of conventional piperazine or morpholine moieties, offering multiple sites for modification with functional groups. We first synthesized the N-protected heterocycles, and then confirmed their utility by synthesizing analogues of the oxazolidinone antibacterial agent linezolid. The analogues exhibited potent in vitro and in vivo antibacterial activity. In particular, compound 10a exhibited good in vivo efficacy when administered intravenously in a murine model of systemic infection with methicillin-resistant Staphylococcus aureus SR3637. These seven-membered heterocycles are expected to be versatile structural units for drug discovery.
合成了七元杂环 [1,2,5] 三氮杂平和 [1,2,5] 氧杂二氮平衍生物,作为药物发现中替代传统哌嗪或吗啉的候选结构,提供了多个功能团修饰位点。我们首先合成了N保护的杂环,然后通过合成抗菌药物氟氯西林的类似物来验证其有效性。这些类似物表现出强大的体外和体内抗菌活性。特别是化合物10a在小鼠模型中采用静脉注射时,对抗耐甲氧西林金黄色葡萄球菌SR3637表现出良好的体内疗效。这些七元杂环有望成为药物发现中多功能的结构单元。
