CH3O greater than CH3 greater than F much greater than COOH. No direct correlation was apparent, nor was there any obvious correlation between biological activity and the extent of base-catalyzed hydrogen-deuterium exchange at the alpha carbons.
测试了鼠伤寒沙门氏菌TA 1535中N-亚硝基-N-(对位取代的苄基)
甲胺的相对诱变性,以确定
生物活性是否受到亚
硝胺α碳上的电子密度的影响。效力的顺序如下:X = Cl大于CN大于Br大于
NO2大于H大于
CH3O大于
CH3大于F大于COOH。没有直接的相关性是明显的,在
生物活性和α-碳上碱催化的氢-
氘交换的程度之间也没有任何明显的相关性。
