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.
本发明涉及一般式的4-羟基哌啶衍生物,其中X表示-O-,-NH-,-CH2-,-CH═,-CHOH-,-CO-,-S-,-SO-或-SO2-;R1-R4独立地表示氢、羟基、较低烷基磺酰胺、1-或2-咪唑基或乙酰胺基;R5-R8独立地表示氢、羟基、较低烷基、卤素、较低烷氧基、三氟甲基或三氟甲氧基;a和b可以是双键,但是当“a”是双键时,“b”不能是双键;n为0-2;m为1-3;p为0或1,并且其药学上可接受的盐。本发明化合物是NMDA(N-甲基-D-天门冬氨酸)受体亚型选择性阻滞剂,可用于调节中枢神经系统发育过程,包括学习和记忆形成和功能。
