A new series of 7-O-substituted pyridyl-4-methyl coumarin derivatives were synthesized and characterized based on their spectral data. All the target compounds were evaluated for their in vitro antifungal activity against eight important fungal pathogens. This study showed that the introduction of the substituted pyridyl moiety at the 7-hydroxy position of coumarin could enhance the antifungal activities
合成了一系列新的7 - O-取代的吡啶基-4-甲基香豆素衍生物,并根据其光谱数据进行了表征。评价所有目标化合物对八种重要真菌病原体的体外抗真菌活性。该研究表明在香豆素的7-羟基位置引入取代的吡啶基部分可以增强抗真菌活性。还表明大的取代基不利于那些香豆素衍生物的抗真菌活性。
