In the present study, a series of 1,3-diaryl pyrazole derivatives bearing rhodanine-3-fatty acid moieties were synthesized and their antimicrobial activities were tested against various Gram-positive and Gram-negative bacteria. 1,3-diaryl-4-formylpyrazoles were synthesized as key intermediates following a Vilsmeier–Haack strategy. Several compounds with an MIC of 2 μg/mL, exhibited stronger antibacterial
在本研究中,合成了一系列带有若丹宁-3-脂肪酸部分的1,3-二芳基吡唑衍生物,并测试了它们对各种革兰氏阳性和革兰氏阴性细菌的抗菌活性。按照维尔斯迈尔-哈克(Vilsmeier-Haack)策略,合成了1,3-二芳基-4-甲酰基吡唑类化合物作为关键中间体。MIC为2μg/ mL的几种化合物显示出比对照更强的耐甲氧西林金黄色葡萄球菌(MRSA)的抗菌活性。这些化合物均未显示出对革兰氏阴性细菌的任何活性。
