a medium-sized alkyl group (isopropyl, tert-butyl, etc.) at the meta position and a carboxyl group at the para position of the other benzene ring. The bonding of the amide structure can be reversed, this moiety apparently having the role of locating the two benzene rings at suitable positions with respect to each other. Substitution at the ring position ortho to the amide group or N-methylation of the
已显示两种类型的芳族酰胺,对苯二甲酸单苯胺和(芳基甲酰胺基)苯甲酸具有有效的类维生素A活性,可以归类为类维生素A。基于对人早幼粒细胞白血病细胞HL-60的分化诱导活性,讨论了这些酰胺的构效关系。在通式4(X = NHCO或CONH)中,引起类视色素活性的必要因素是在其间位的中等尺寸烷基(异丙基,叔丁基等)和在其对位的羧基。另一个苯环。酰胺结构的键可以颠倒,该部分显然具有将两个苯环相对于彼此定位在适当位置的作用。推测是由于所得的构象变化,在酰胺基邻位的环位置取代或酰胺基的N-甲基化导致活性降低。显然,苄基甲基和羧基的相互取向以及它们之间的距离是决定类视色素活性的必要因素。在合成的化合物中,4-[((5,6,7,8-四氢-5,5,8,8-四甲基-2-萘基)氨基甲酰基]苯甲酸(Am80)和4-[(5,6,在该测定中,7,8-四氢-5,5,8,8-四甲基-2-萘基[羧酰胺基]苯甲酸(Am580)的
