In the continuation of our study of substituted isocoumarins a series of novel 3-azolyl isocoumarin and their thio derivatives, including some related lactone compounds was prepared and biologically profiled against C. albicans showing moderate activity with MIC values in range of 4?60 ?g mL-1, in general. The additional characterisation of selected compounds was carried out by exploring their activity on CYP3A4 and CYP2D6 enzymes, while experiments on mutagenicity were performed by AMES test. The representative isocoumarins 3b, 4a and 4b showed lower inhibitory activity on CYP enzymes, when compared to the reference inhibitors, ketoconazole and quinidine. Compound 4a showed a higher mutagenic potential than the other two compounds. Further characterization included cytotoxicity profiling against normal MRC5 cells.
为了继续研究取代的异香豆素,我们制备了一系列新型 3-azolyl 异香豆素及其硫代衍生物,包括一些相关的内酯化合物,并对这些化合物进行了生物分析,结果表明它们对白僵菌具有中等程度的活性,一般 MIC 值在 4?对所选化合物的其他特征描述是通过探究它们对 CYP3A4 和 CYP2D6 酶的活性进行的,而诱变性实验则是通过 AMES 试验进行的。与参考抑制剂酮康唑和奎尼丁相比,具有代表性的异香豆素 3b、4a 和 4b 对 CYP 酶的抑制活性较低。化合物 4a 的诱变潜力高于其他两种化合物。进一步的表征包括对正常 MRC5 细胞的细胞毒性分析。
