Description

吡咯-2-甲酰胺类化合物及其制备方法和用途 技术领域
本发明属于医药技术领域。特别涉及通式(I)所示的吡咯-2-甲酰胺类化合物及其制备方法、药物组合物和其在制备治疗和/或预防由结核分枝杆菌引起的感染性疾病药物中的用途。
背景技术
结核病(tuberculosis,TB)是由结核分枝杆菌引起的一种慢性致死性疾病,是危害人类健康和导致人类死亡的重大传染性疾病,结核病现在与艾滋病一样,成为全世界主要死亡原因之一。据世界卫生组织(WHO)估计(Global tuberculosis report 2015):全世界有960万人在2014年罹患结核病(540万男人、320万妇女和100万儿童),死亡150万例(110万艾滋病毒阴性患者和40万艾滋病毒阳性患者),死亡病例包括89万男人、48万妇女和14万儿童。
化学治疗是结核病治疗的主要手段。1944年链霉素的使用,开创了抗结核药物治疗的新时代,随着异烟肼、利福平、吡嗪酰胺的相继出现,使得治疗结核病疗程缩短到6个月,进入了“短程化疗时代”。尽管如此,长期药物联合治疗,使患者产生不良反应,难以坚持规律用药,加之所用药物多诞生于上世纪五六十年代,长期、广泛及不规范使用使得耐药菌发展日趋严重,出现多药耐药结核(MDR-TB)、广泛耐药结核(XDR-TB)与全部耐药结核(TDR-TB)。面对耐药结核,需使用价格昂贵且毒性较大的二线甚至三线抗结核药物。
鉴于以上情况,本领域仍需研究开发结构新颖、抗结核活性更强、毒副作用更低,药代动力学性质优良的抗结核药物。
发明内容
本发明要解决的技术问题是提供一种具有新颖结构且安全有效的抗结核及耐药结核的吡咯-2-甲酰胺类化合物。本发明人发现,该类化合物具有强的体内外抗结核分枝杆菌活性,从而提供了一类结构新颖、抗结核活性强的化合物,可用于结核病的治疗。本发明基于以上发现而得以完成。
为解决本发明的技术问题,本发明提供如下技术方案:
本发明技术方案第一方面提供通式(I)所示的化合物或其药学上可接受的盐,
