N-Substituted derivatives of 7-(3-amino-2-hydroxypropyl)-8-benzyl- (V), or -8-phenyltheophylline (VI) were prepared by addition of the appropriate amines to 7-epoxypropyl-8-benzyl- (III), or -8-phenyltheophyllines (IV). Compounds III and IV were obtained by alkylation of 8-benzyl-, or 8-phenyltheophyllines with 1-chloro-2,3-epoxypropane. DerivativesV and VI exhibited a peripheral vasodilatation effect in vitro.
将7-(3-氨基-2-羟基丙基)-8-苄基-(V),或8-苯基茶碱(VI)的N-取代衍生物通过将适当的胺添加到7-环氧丙基-8-苄基-(III),或8-苯基茶碱(IV)中制备。化合物III和IV是通过用1-氯-2,3-环氧丙烷烷基化8-苄基-或8-苯基茶碱而获得的。衍生物V和VI在体外表现出外周血管扩张作用。
