The antifungal activity of 37 N-(methoxy-substituted benzoyl)anthranilic esters was tested on the powdery mildew of barley caused by Erysiphe graminis by the pot test. Among the methyl N-(methoxy-substituted benzoyl)anthranilates tested, 3, 4-dimethoxybenzoyl derivative exhibited the highest activity. The variation in fungicidal activity of N-(3, 4-dimethoxy-benzoyl)anthranilic esters was shown to be related with variation in hydrophobicity and the electronic property of the alcohol moiety of the ester. The branching at the α-position of the alcohol moiety of the ester was detrimental to the activity.
37种N-(甲氧基取代的苯甲酰)蒽醌酯的抗真菌活性通过盆栽试验在由小麦白粉病(Erysiphe graminis)引起的大麦粉状霉菌上进行了测试。在测试的甲基N-(甲氧基取代的苯甲酰)蒽醌酯中,3,4-二甲氧基苯甲酰衍生物表现出最高的活性。N-(3,4-二甲氧基苯甲酰)蒽醌酯的杀真菌活性的变化被证明与酯的醇基的疏水性和电子性质的变化相关。醇基在α位的支链对活性是有害的。
