Description
技术领域
本发明涉及芳香2-丁醇类化合物,其光学异构体、消旋体、非对映异构体及其药学可接受的盐。本发明还涉及制备式I化合物的方法、含有上述化合物的药用组合物以及所述化合物用于抗结核杆菌的用途。
背景技术
继艾滋病之后,结核病又是一危害世界的重大感染性疾病,每年造成2-3百万的患者死亡。世界上已有1100万人综合感染了爱滋病毒和结核杆菌,艾滋病患者发病同时,由于免疫力低下,此前一度休眠的结核杆菌便大肆泛滥,而且随着感染艾滋病毒的人数的与日俱增,结核的感染率又了抬头的趋势。由于种种原因,近40年来没有任何上市的药物。虽然现有的一线抗结核用药能很大程度上遏制着结核杆菌的蔓延,但是随着耐药性菌株的增多以及交叉耐药出现,前景不容乐观。此外,现用于临床的抗结核药物的治疗周期都在6个月以上,如此长的治疗时间不但患者很难坚持下来,而且使得耐药菌株的数量不断增多,因此必须要有快速治疗的抗结核药物。鉴于此,本技术领域需要发展全新结构和作用于新靶点的抗结核药物。
ATP合成酶作为一个全新的抗结核靶点,有着很好的应用前景。新型芳香2-丁醇类化合物就是针对此靶点设计的抗结核杆菌化合物。

实施例31:应用Microplate Alamar Blue Assay(MABA)法测定化合物对结核分枝杆菌标准株H37Rv的最低抑菌浓度(MIC)。
方法:无菌96孔板(Falcon3072;Becton Dickinson,LincolnPark,N.J.),实验化合物以二甲基亚砜溶解,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:12.5、6.25、3.125、1.56、0.78、0.39、0.2、0.1、0.05、0.025、、0.0125μg/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(Setotec公司产品)和5%Tween8050μl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Tween80混合液,37℃孵育24小时记录各孔的颜色,MIC定义为阻止颜色变化(从蓝色变为粉红色)的最低药物浓度。
结果
