A pyrimidine derivative or analogue comprises an amino-substituted six-membered heterocyclic moiety, moiety A, linked through a linker L to a moiety B, where B is a carboxylic acid, a carboxylic acid ester, or a moiety of the structure N(Y
1
)-D, where Y

can be one of a variety of substituents, including hydrogen or alkyl, and D is a moiety that enhances the pharmacological effects, promotes absorption, or promotes blood-brain barrier penetration of the derivative or analogue. The moiety A can have two or three nitrogen atoms in the ring; typically, the moiety A is a pyrimidine moiety, with two nitrogen atoms in the ring. The moiety B can be one of a variety of moieties, including moieties having nootropic activity or other biological or physiological activity.
一种嘧啶衍生物或类似物包括一种氨基取代的六元杂环基团A,通过连接物L连接到一种基团B,其中B是一种羧酸、羧酸酯,或结构为N(Y1)-D的基团,其中Y1可以是多种取代基之一,包括氢或烷基,D是一种增强药理效应、促进吸收或促进血脑屏障穿透的基团。基团A的环中可以有两个或三个氮原子;通常,基团A是一种嘧啶基团,环中有两个氮原子。基团B可以是多种基团之一,包括具有智力活性或其他生物学或生理活性的基团。
