Eleven new 2-styrylbenzothiazole-N-oxides have been prepared by aldol – type condensation reactions between 2-methylbenzothiazole–N-oxide and para-substituted benzaldehydes. Compounds with cyclic amino substituents showed typical push-pull molecule properties. Four compounds were tested against various bacterial strains as well as the protozoan Euglena gracilis as model microorganisms. Unlike previously prepared analogous benzothiazolium salts, only weak activity was recorded.
通过芳基醛与2-甲基苯并噻唑-N-氧化物之间的醛缩反应制备了十一种新的2-苯乙烯基苯并噻唑-N-氧化物。带有环状氨基取代基的化合物显示出典型的推-拉分子特性。对四种化合物进行了对抗各种细菌菌株以及原生动物优格莱纤毛虫作为模型微生物的测试。与先前制备的类似苯并噻唑盐相比,仅记录到弱活性。
