Abstract
Description
技术领域
本发明属于医药技术领域。特别涉及通式(I)所示的取代吡咯-2,5-二酮类化合物,其制备方法,以该化合物为活性成分的药物组合物,以及它们在治疗和/或预防由结核分枝杆菌引起的感染性疾病中的应用。
背景技术
结核病(Tuberculosis,TB)是由结核分枝杆菌引起的肺部感染致死性传染病。结核病作为十大致死性疾病之一,现已超越艾滋病成为单一致死性感染疾病之首。根据世界卫生组织2021年结核病研究报告显示,2020年全球约有990余万新发结核病患者。近年来随着耐药结核发病率的增高以及TB/HIV共感染的增加,结核病的防控面临着严重的挑战,研制具有新结构、新机制的抗结核新药迫在眉睫。
发明内容
本发明要解决的技术问题是提供一种结构新颖并具有抗结核分枝杆菌活性的取代吡咯-2,5-二酮类化合物。本发明发现,取代吡咯-2,5-二酮类化合物具有较强的抗结核分枝杆菌作用,可用于由细菌引起的感染性疾病,特别是由分枝杆菌引起的肺结核疾病的治疗或预防性治疗,同时可用于克服与耐药性有关的问题。本发明基于以上发现而得以完成。

实验原理:Alamar Blue加入培养基可作为氧化还原指示剂,颜色由蓝色向红色转变,反映所研究的微生物对氧分子的消耗。Alamar Blue的颜色改变可用光度计测定,其发射波长为590nm。
实验方法:无菌96孔板(Falcon3072;Becton Dickinson,Lincoln Park,N.J.),实验化合物以DMSO溶解,制成浓度为5mg/mL的初溶液,最高浓度孔加入199μL 7H9培养基,1μL化合物初溶液,混合均匀后,向其余各孔依次2倍稀释,化合物终浓度为:25、12.5、6.25、3.125、1.56、0.78、0.39、0.2、0.1、0.05μg/mL。选取结核分枝杆菌H37Rv培养2~3周的培养物制成菌悬液,接种到含0.05%吐温80、10%ADC的7H9培养基中,37℃静止培养1~2周,生长至浊度为McFarland 1(相当于107CFU/mL)时,1:20稀释后,加入各孔100μL,菌液的终浓度为106CFU/mL。每板上均设2个不含抗菌药的生长对照孔,96孔板于37℃孵育。7天后加入生长对照孔20μL 10×Alamar Blue和5%Tween80 50μL的混合液,37℃孵育24小时,如果颜色从蓝色变为粉色,则在各实验药物的孔内加入上述量的Alamar Blue和Tween 80混合液,37℃孵育24小时记录各孔的颜色,并应用酶标仪测定590nm荧光值,计算MIC90。
