A new series of N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) have been synthesized by a cyclo-condensation reaction of 2-bromo-1-(1,3-diphenyl-1H-pyrazol-4-yl)ethanone (6a-f) with N-aryl thiourea, (7a-d). The structure of newly synthesized N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) derivatives was analyzed by 1H NMR, 13C NMR and Mass spectral analysis. The compounds
通过2-溴的环缩合反应合成了一系列新的N-芳基-4-(1,3-二芳基-1 H-吡唑-4-基)噻唑-2-胺, ( 8a-x ) -1-(1,3-二苯基-1H-吡唑-4-基)乙酮( 6a-f )与N-芳基硫脲,( 7a-d )。新合成的N-芳基-4-(1,3-二芳基-1H-吡唑-4-基)噻唑-2-胺,( 8a-x )衍生物的结构通过1 H NMR、13 C NMR 和质谱分析。筛选了化合物8a-x对大肠杆菌、奇异变形杆菌、枯草芽孢杆菌、金黄色葡萄球菌、白色念珠菌和黑曲霉的体外抗菌活性。以及针对结核分枝杆菌H37Rv 菌株的抗结核活性。在24种吡唑基噻唑衍生物中,6种化合物8a、8b、8j、8n、8o和8s显示出良好的抗金黄色葡萄球菌活性。针对黑曲霉,所有合成的衍生物均表现出良好的抗真菌活性。15 个吡唑基噻唑衍生物8a、8f、8g、8h、8j、8k、8n、8o、8p、8q、8r、8s、8t、8w和8x显示出良好的抗结核活性,
