本周的Nature Medicine报道,一种新的药物Q203能够抑制结核分枝杆菌生长,这一发现可能会提高治疗的耐药结核病(TB)的治疗选择。

世界三分之一人口受到结核分枝杆菌的潜伏感染,每年超过百万人死于结核病。耐多药结核分枝杆菌菌株已经广泛传播,因此,开发新的和改进的药物迫在眉睫。

韩国学者Kevin Pethe及其同事筛选了巨噬细胞中的结核分枝杆菌生长抑制剂的化学库,并确定imidazopyrimidine amides作为潜在治疗药物。团队优化了这些化学物质后合成复合Q203。该化合物在体外和在小鼠模型结核病治疗中显示出疗效,可抑制ATP的合成,进而抑制结核杆菌生长。 

该研究证实,一种新的合成抗菌分子(Q203)与现有的很多抗结核药物相比,细菌更难以对其产生耐药性。如果临床试验证明其对人类安全、有效,将有望挽救更多人的生命。

抗菌药物在慢性病患者中的不良反应

 随着人口老龄化,慢性病已成为主要的疾病负担。慢性病患者常需要同时服用几种不同的药物以控制病情,若再使用抗感染药物,则更易出现各种不良反应。因此,应关注抗菌药物在慢性病患者中应用时出现的不良反应。   药物相互作用可分为三类,即药物与药物相互作用(下表)、药物与食物-饮料相互作用、药物与疾病状态相互作用。在慢性病患者中,这三种相互作用常相互联系,难以独立和区分。   神经疾病   中枢
