Abstract
Description
技术领域
本发明属于药物合成领域,具体涉及一种苯并噻唑并嘧啶环化合物及其制备方法和用途。
背景技术
由于杂环化合物具有广泛的生物活性,加之其低毒、高效、对环境友好等特点,已经成为药物开发的热点。在杂环化合物中,具有高生物活性的稠杂环化合物已受到极大关注。到目前为止,已经有很多含稠杂环的化合物被报道具有广泛的生物活性,如抗癌、消炎、抗菌等。
比如中国专利申请(201010266621.6)公开了以下式b所示的苯并咪唑衍生物,该稠杂环衍生物能够抑制MAP激酶Erk的蛋白/蛋白相互作用,能够诱导人类癌细胞系中的凋亡,具有良好的抗癌效果。再如Suresh等(Suresh,M.;Sridevi,G.;Nuthangi,S.;Palakondu,L.;Sreekanth,B.J.Arabian J.Chem.2016,9,681)将嘧啶药效团引入到苯并噻唑结构中合成的系列含苯并噻唑的化合物,具有较强的抗菌活性,如以下式a所示的化合物就对金黄色葡萄球菌与化脓性链球菌均具有较强的抗菌活性。
但是,随着抗生素在临床治疗上的广泛使用(甚至滥用),产生了越来越严重的细菌耐药性问题,这导致一些抗生素的疗效下降甚至失效,一些非致病性细菌如变形杆菌、绿脓杆菌等成为致病菌,甚至出现了对大部分抗菌药物都不敏感的“超级细菌”。细菌耐药性被世界卫生组织看作是21世纪最大的公共卫生安全问题之一,引起了广泛关注,在这种情况下,迫切需要开发新型的抗菌药物。
因此,开发出一类具有新型母核结构的抗菌药物,将具有非常重要的应用价值。
