A new series of alkyl α‐[5‐(5‐nitro‐2‐furyl)‐1, 3, 4‐ thiadiazole‐2‐ylthio] and α‐[5‐(1‐methyl‐5‐nitro‐2‐imidazolyl)‐1, 3, 4‐thiadiazole‐2‐ylthio]acetates (6a–e, 6f–j) were synthesized and evaluated against Mycobacterium tuberculosis as part of the TAACF (Tuberculosis Antimicrobial Acquisition and Coordinating Facility) TB screening program. Primary screening was conducted at the single concentration
新系列烷基α-[5-(5-硝基-2-呋喃基)-1,3,4-噻二唑-2-基硫基]和α-[5-(1-甲基-5-硝基-2-咪唑基) ) -1, 3, 4-噻二唑-2-基硫基] 乙酸酯 (6a – e, 6f – j) 作为 TAACF(结核病抗微生物采集和协调设施)结核病筛查计划的一部分被合成和评估针对结核分枝杆菌。使用肉汤微量稀释测定法,Microplate Alamar Blue Assay (MABA),以 6.25 μg/mL 的单一浓度针对 BACTEC 12B 培养基中的结核分枝杆菌 H37Rv 进行初步筛选。对于在初步筛选中表现出> 90% 生长抑制的化合物,确定了最小抑制浓度(MIC)。七种化合物是有效的抗分枝杆菌剂,MIC 值范围为 0.78 至 6.25 μg/mL。在硝基呋喃衍生物中,甲基(6a)、乙基(6b)、和苄基(6e)酯表现出良好的抗结核活性(MIC = 0.78-3
