    • The present invention relates to 4-hydroxy-piperidine derivatives of the general formula wherein X denotes —O—, —NH—, —CH2—, —CH═, —CHOH—, —CO—, —S—, —SO— or —SO2—; R1-R4 are, independently from each other, hydrogen, hydroxy, lower-alkyl-sulfonylamino, 1- or 2-imidazolyl or acetamido; R5-R8 are, independently from each other, hydrogen, hydroxy, lower-alkyl, halogen, lower-alkoxy, trifluoromethyl or trifluoromethyloxy; a and b may be a double bond, provided that when “a” is a double bond, “b” cannot be a double bond; n is 0-2; m is 1-3; p is 0 or 1 and to pharmaceutically acceptable addition salts thereof. Compounds of the present invention are NMDA(N-methyl-D-aspartate)-receptor subtype selective blockers, which can be used in mediating processes underlying development of CNS including learning and memory formation and function.
    • 本发明涉及通式为Ⅳ的4-羟基 - 哌啶衍生物,其中X表示-O - , - NH - , - CH 2 - , - CH =, - CHOH-, - CO - , - S - , - SO-或-SO 2 - ; R 1 -R 4彼此独立地为氢,羟基,低级 - 烷基 - 磺酰基氨基,1-或2-咪唑基或乙酰氨基; R5-R8彼此独立地为氢,羟基,低级 - 烷基,卤素 低级烷氧基,三氟甲基或三氟甲氧基; a和b可以是双键,条件是当“a”是双键时,“b”不能是双键; n是0-2; m是1-3; p是0或1,以及其药学上可接受的加成盐。本发明的化合物是NMDA(N-甲基-D-天冬氨酸) - 受体亚型选择性阻断剂,其可用于介导中枢神经系统发育的过程,包括学习和记忆形成 和功能。
