The present invention provides new basically substituted pyridinecarboxamides having the formula I ##STR1## wherein R.sub.1 represents lower alkyl and --OR.sub.1 is in the adjacent position to the carboxamide group, R.sub.2 represents lower alkyl or an ethylene radical which is attached to one of the trivalent radicals designated as A and the nitrogen atom located between it to form a 6-membered ring, A represents a divalent saturated hydrocarbon radical which encompasses at most a single ring with 5 or 6 ring members and contains not more than 7 carbon atoms and whose two linkage positions are separated by (3-m) to 4 carbon atoms, or, if R.sub.2 is an ethylene radical, represents the 1-propanyl-3-ylidene radical, if m s 1, or the 1,2,4-butane-triyl radical, if m is 0, And one of the factors m and n is 0 and the other is 1, and, if desired, the ring B is further substituted, and the acid addition salts of the compounds of the formula I. These new substances possess useful pharmacological properties, in particular antiemetic, psychosomatic and antipsychotic activity and can be used for the treatment of thought disturbances and of states of psychomotor excitation. Specific embodiments are N-[(1-ethyl-2-pyrrolidinyl)-methyl]-2,6-dimethoxynicotinamide and the pharmaceutically acceptable acid addition salts thereof.
本发明提供了具有公式I的新的基本取代的吡啶羧酰胺化合物:
其中,R1代表低碳基,-OR1位于羧酰胺基团的相邻位置;R2代表低碳基或与被指定为A的三价基团之一和位于其之间的氮原子连接形成6元环的乙烯基;A代表双价饱和碳氢基团,最多包含一个由5或6个环成员组成的环,并且其两个连接位置被(3-m)到4个碳原子分开,或者如果R2是乙烯基,则表示1-丙基-3-基亚甲基基团,如果m为1,则表示1,2,4-丁三基基团;m和n中的一个因子为0,另一个因子为1,如果需要,环B可以进一步取代,以及公式I化合物的酸加成盐。这些新物质具有有用的药理特性,特别是抗恶心、心理身体和抗精神病活性,并可用于治疗思维障碍和心理运动兴奋状态。具体实施例是N-[(1-乙基-2-吡咯烷基)-甲基]-2,6-二甲氧基烟酰胺及其药学上可接受的酸加成盐。
