A series of pyprimidinyl compounds of formulae I, II and III; ##STR1## wherein R.sup.1 and R.sup.2 are independently selected from hydrogen and hydroxy; R.sup.3 is selected from hydrogen, hydroxy, or oxo, with the proviso that R.sup.3 can only be oxo when R.sup.1 and R.sup.2 are hydrogen, and further that R.sup.1, R.sup.2, and R.sup.3 cannot all be hydrogen or hydroxy at the same time; and the solid and dotted lines refer to either a double covalent bond or a single covalent bond with another hydrogen atom covalently bonded to the carbon terminus end. The compounds of this invention possess cognition and memory enhancing activity.
一系列的吡啶基化合物,化学式为I、II和III;其中R.sup.1和R.sup.2分别选择自氢和羟基;R.sup.3选择自氢、羟基或氧化物,但需要注意的是当R.sup.1和R.sup.2为氢时,R.sup.3只能是氧化物,而且R.sup.1、R.sup.2和R.sup.3不能同时为氢或羟基;实线和虚线表示双共价键或与碳末端共价结合的另一个氢原子的单共价键。本发明的化合物具有增强认知和记忆能力的活性。
