Methyl N-(substituted benzoyl)anthranilates were found to possess inhibitory activity against the powdery mildew of cucumber caused by Sphaerotheca fuliginea. Both the anthranilate and the N-benzoyl moieties were essential for this type of fungicidal activity. Substitution at the 2- and 4-positions of the N-benzoyl group was unfavorable to the activity except for the 4-methoxy group. Substitution at the 3-position varied the fungicidal activity to various extents. The variation in the activity of 3-substituted derivatives was analyzed quantitatively with substituent parameters and regression analysis indicating that the variation in the steric dimension of substituents was most responsible for the activity.
甲基N-(取代苯甲酰基)邻氨基苯甲酸酯被发现对瓜类白粉病具有抑制活性,该病由单丝壳属的真菌引起。邻氨基苯甲酸和N-苯甲酰基对于这种类型的杀菌活性都是必不可少的。N-苯甲酰基的2位和4位取代不利于活性,除非是4-甲氧基。3位取代会以不同程度改变杀菌活性。通过对取代基参数的定量分析和回归分析表明,取代基的空间尺寸变化最能够解释活性的变化。
