inhibitory concentration required to inhibit the growth of E. coli, M. luteus and A. niger. The series displays a wide range of activities with 2-chloro-3,5-dinitrothiophene (3a) or 2-bromo-3,5-dinitrothiophene (3c) showing the highest activity against all three organisms, while the simplest compound of the series, 2-nitrothiophene (3s) shows the smallest activity in each case. The mode of action of 3a and
已经通过评估抑制大肠杆菌,黄体分枝杆菌和黑曲霉的生长所需的最小抑菌浓度,评估了十九种取代噻吩的生物活性(3)。该系列显示出广泛的活性,其中2-氯-3,5-二硝基噻吩(3a)或2-溴-3,5-二硝基噻吩(3c)对三种生物均显示出最高的活性,而该系列中最简单的化合物,2-硝基噻吩(3s)在每种情况下均显示最小的活性。人们认为3a和3c的作用方式涉及细胞内硫醇在杂环2位上的亲核攻击,导致卤素置换,但其他活性衍生物(例如2)
