Piperidine compounds having the general general Formula I
wherein R1 is
a group consisting of alkyl, alkenyl, cycloalkyl, cycloalkenyl, phenyl, cycloalkylalkyl, cycloalkenylalkyl, phenylalkyl or diphenylalkyl linked to the piperidyl N-atom through an at least 2 membered spacer group or;
R2 and R3 are hydrogen, or alkyl or they may together form an ethylene or propylene bridge; R4 to R7 are substituents; and
Z1 is CH2, O or S; Z2 and Z3 are independently (CH2)n, n being 0 or 1, O or S or Z1 and Z2 may together represent a group -CH=CH-; or when Z3 is (CH2)n wherein n is 0, Z1 and Z2 may together represent a 3-membered divalent group;
show potent sigma receptor activity. Furthermore they show effect in animal models indicative of anxiolytic properties. Accordingly they are useful as medicines for the treatment of anxiety, psychosis, epilepsy, convulsion, movement disorders, motor disturbances, amnesia, cerebrovascular diseases, senile dementia of the Alzheimer type or Parkinson's disease.
具有一般通式 I 的哌啶化合物
其中 R1 是
由烷基、烯基、环烷基、环烯基、苯基、环烷基烷基、环烯基烷基、苯基烷基或二苯基烷基组成的基团,通过至少2个成员的间隔基团与哌啶基N原子相连;或
R2 和 R3 是氢、烷基或可共同形成乙烯桥或丙烯桥;R4 至 R7 是取代基;以及
Z1 是 CH2、O 或 S;Z2 和 Z3 独立地是 (CH2)n(n 为 0 或 1)、O 或 S,或者 Z1 和 Z2 可共同代表一个基团 -CH=CH-;或者当 Z3 是 (CH2)n 时(其中 n 为 0),Z1 和 Z2 可共同代表一个三元二价基团;
显示出强大的 sigma 受体活性。此外,它们在动物模型中显示出抗焦虑特性。因此,它们可用作治疗焦虑症、精神病、癫痫、抽搐、运动障碍、运动失调、健忘症、脑血管疾病、阿尔茨海默型老年痴呆症或帕金森病的药物。
