Tetrahydropyridine derivatives represented by general formula (I) (wherein R1 represents an unsubstituted or substituted saturated cycloalkyl group, R2 and R3 each represents halogen, unsubstituted or substituted alkyl, aryl, alkenyl, acyl or arylcarbonyl, and m and n each represents an integer of 0 to 4 provided that R2 groups and R3 groups may be the same or different when m and n are 2 or more) and acid addition salts thereof are disclosed. These compounds are useful as psychotropic drugs acting on central nerves of mammals to exhibit psychoac- tivating, antianxiety, and learning-improving effects which have been found by the inventors for the first time.
本发明公开了通式(I)代表的四氢
吡啶衍生物(其中R1代表未取代或取代的饱和环烷基,R2和R3各自代表卤素、未取代或取代的烷基、芳基、烯基、酰基或芳基羰基,m和n各自代表0至4的整数,但当m和n为2或2以上时,R2基团和R3基团可以相同或不同)及其酸加成盐。这些化合物可作为精神药物作用于哺乳动物的中枢神经,表现出精神兴奋、抗焦虑和提高学习能力的效果,这些效果是本发明人首次发现的。
