A few 4-allyl/amino-5-aryl-1,2,4-triazoles were synthesized and tested for antibacterial and antifungal effects against Escherichia coli, Bacillus subtilis, Salmonella enteritidis, Staphylococcus aureus, Aspergillus niger and Candida albicans. 4-Allyl-5-aryl-1,2,4-triazoles were obtained by the oxidative cyclization of the appropriate 1-substituted-4-allylthiosemicarbazides and 4-amino-5-aryl-1,2,4-triazoles were obtained by cyclization of the potassium salts of appropriately substituted dithiocarbazinic acids with hydrazine hydrate. The new synthesized compounds were characterized using IR, 1H- NMR, 13C-NMR and UV spectral data together with elemental analysis.
合成了几种4-烯丙基/氨基-5-芳基-1,2,4-三唑并测试了它们对大肠杆菌、枯草芽孢杆菌、沙门氏菌、金黄色葡萄球菌、黑曲霉和白色念珠菌的抗菌和抗真菌效果。4-烯丙基-5-芳基-1,2,4-三唑通过适当的一取代-4-烯丙基缩氨基硫脲的氧化环合得到,而4-氨基-5-芳基-1,2,4-三唑通过适当取代的二硫代氨基甲酸钾盐与水合肼的环合反应得到。这些新合成的化合物通过IR、1H-NMR、13C-NMR和UV光谱数据以及元素分析进行了表征。
