A series of novel 2-aryl-3,4-dihydro-2H-thieno[3,2-b]indoles has been synthesised regioselectively in good yields from the reaction of 5-aryldihydro-3(2H)-thiophenones and arylhydrazine hydrochloride. This reaction is found to be assisted by microwaves. The thieno[3,2-b]indoles were evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv (MTB) and multi-drug resistant M. tuberculosis
从5-芳基二氢-3(2 H)-噻吩与芳基肼的反应中,高选择性地合成了一系列新颖的2-芳基-3,4-二氢-2 H-噻吩并[3,2- b ]吲哚。盐酸盐。发现该反应由微波辅助。评价了噻吩并[3,2- b ]吲哚对结核分枝杆菌H37Rv(MTB)和耐多药结核分枝杆菌(MDR-TB)的体外活性。在筛选出的22种化合物中,发现[2-(2,4-二氯苯基)-7-氟-3,4-二氢-2 H-硫代[3,2- b ]吲哚](6t)是活性最高的化合物。相对于MTB和MDR-TB的MIC为0.4μg/ mL。
