study, we evaluated the antifungal effect of 23 ester derivatives of the cinnamic and benzoic acids against 3 C. albicans strains (ATCC-76645, LM-106 and LM-23), as well as discuss their Structure–Activity Relationship (SAR). The antifungal assay results revealed that the screened compounds exhibited different levels of activity depending on structural variation. Among the ester analogues, methyl caffeate
白色念珠菌是一种重要的机会真菌病原体,能够引起人类感染。在本研究中,我们评估了肉桂酸和苯甲酸的23种酯衍生物对3 C. albicans菌株(ATCC-76645,LM-106和LM-23)的抗真菌作用,并讨论了它们的结构-活性关系( SAR)。抗真菌测定结果表明,所筛选的化合物根据结构变化表现出不同的活性水平。在酯类似物中,咖啡因甲酯(5)和2-硝基肉桂酸甲酯(10)是对所有白色念珠菌具有最佳抗真菌作用的类似物。菌株,呈现相同的MIC值(MIC = 128μg/ mL),然后是联苯-2-羧酸甲酯(21)(白色念珠菌LM-106,LM-23,MIC = 128、128和256μg/ mL )和ATCC-76645)。我们的结果表明某些分子特性对于抗真菌作用很重要。
