Disclosed are a compound represented by formula (1) and a non-toxic salt thereof, a production method thereof, and a pharmaceutical composition for treating a serotonergic neuron-related disease comprising the same as an active ingredient: ##STR1## wherein R.sup.1 represents a hydrogen atom or a lower alkyl group; R.sup.2 represents a pyridyl group which is unsubstituted or substituted with 1 to 3 substituents each independently selected from the group consisting of a halogen atom, a lower alkyl group, a trifluoromethyl group, a lower alkoxy group, a carbamoyl group and a cyano group, or a pyrimidinyl group which is unsubstituted or substituted with 1 to 2 substituents each independently selected from the group consisting of a lower alkyl group and a lower alkoxy group; and n is an integer of from 2 to 5. Compound (1) of the present invention and a non-toxic salt thereof have a strong affinity for serotonin 1A receptor and, therefore, they are useful for preventing and treating serotonergic neuron-related diseases, such as motion sickness, space sickness, emesis, dizziness, depression, anxiety, eating disorder, and the like.
本发明公开了一种由式(1)表示的化合物及其无毒盐,其制备方法,以及包含其作为活性成分的用于治疗与5-羟色胺神经元相关疾病的药物组合物:##STR1##其中R.sup.1代表氢原子或较低的烷基基团;R.sup.2代表未取代或取代有1至3个取代基的吡啶基,每个取代基独立地选自卤原子、较低的烷基基团、三氟甲基基团、较低的烷氧基团、氨基甲酰基团和氰基等团组成的群,或未取代或取代有1至2个取代基的嘧啶基,每个取代基独立地选自较低的烷基基团和较低的烷氧基团;n为2至5的整数。本发明的化合物(1)及其无毒盐对5-羟色胺1A受体具有很强的亲和力,因此它们对预防和治疗与5-羟色胺神经元相关的疾病,如晕动病、太空病、呕吐、头晕、抑郁、焦虑、进食障碍等非常有用。
