Isatin, its 5-chloro and 5-bromo derivatives have been reacted with N-[4-(4'-chlorophenyl)thiazol-2-yl] thiosemicarbazide to form Schiff bases and the N-Mannich bases of these compounds were synthesized by reacting them with formaldehyde and three secondary amines. Their chemical structures have been confirmed by means of IR, 1H-NMR data and by elemental analysis. Investigation of antimicrobial activity
Isatin及其5-氯和5-溴衍生物已与N- [4-(4'-氯苯基)噻唑-2-基]硫代氨基脲反应形成席夫碱,并通过反应合成了这些化合物的N-曼尼希碱他们与甲醛和三种仲胺。它们的化学结构已通过IR,1 H-NMR数据和元素分析得到证实。通过琼脂稀释法对化合物的抗菌活性进行了研究,以针对28种病原菌,8种致病性真菌以及针对HIV在MT-4细胞中复制HIV-1(IIIB)的活性。在测试的化合物中,1- [N,N-二甲基氨基甲基] -5-溴异丁3-3- 1'-[4“-(对氯苯基)噻唑-2”-基]硫代半carb} 10显示出最有利的抗菌剂活动。
