A series of thirteen new thiadiazole compounds were synthesized and evaluated for in vitro antifungal and antibacterial activity. All compound tested showed significant antifungal activity against all the micromycetes, compared to the commercial fungicide bifonazole. Differences in their activity depend on the substitution of different reactive groups. More specifically, best antifungal activity was shown for the synthetic analogue with methylpiperazine reactive group. Furthermore, it is apparent that different compounds reacted on different ways against bacteria. An effort was made to correlate the above mentioned differences in activity with lipophilicity studies. Furthermore, NMR and molecular modelling were used to obtain the main conformational features of a potent analogue, for future in silico studies.
研究人员合成了一系列新的噻二唑化合物,并对其体外抗真菌和抗细菌活性进行了评估。与商用杀真菌剂联苯苄唑相比,所有测试化合物对所有小霉菌都具有明显的抗真菌活性。它们的活性差异取决于不同反应基团的取代情况。更具体地说,带有甲基哌嗪活性基团的合成类似物显示出最佳的抗真菌活性。此外,不同化合物对细菌的反应方式显然也不同。我们努力将上述活性差异与亲脂性研究联系起来。此外,研究人员还利用核磁共振和分子建模技术获得了一种强效类似物的主要构象特征,以便今后进行硅学研究。
