New .alpha.-aryl-.alpha.-pyridylalkanoic acid derivatives of the formula: ##STR1## wherein R.sup.1 is cyano or carbamoyl, R.sup.2 is hydrogen or halogen, R.sup.3 is hydrogen or lower alkyl, one of R.sup.4 and R.sup.5 is hydrogen and another is lower alkyl, R.sup.6 is hydrogen or lower alkyl, and R.sup.7 is lower alkyl, or R.sup.6 and R.sup.7 are taken together to form an N-containing saturated heterocyclic group with the adjacent nitrogen atom, in which the heterocyclic group may be substituted with lower alkyl or optionally protected hydroxy(lower)alkyl, provided that R.sup.2 is halogen or R.sup.3 is lower alkyl, when R.sup.1 is cyano and R.sup.6 and R.sup.7 are each lower alkyl, and salts thereof, and processes for preparation thereof and pharmaceutical composition comprising the same. These derivatives and salts thereof are useful as antiulcer agents and spasmolytic agents.
新的.alpha.-芳基-.alpha.-吡啶基脂肪酸衍生物的化学式为:##STR1## 其中R.sup.1是氰基或氨基甲酰基,R.sup.2是氢或卤素,R.sup.3是氢或较低的烷基,R.sup.4和R.sup.5中的一个是氢,另一个是较低的烷基,R.sup.6是氢或较低的烷基,而R.sup.7是较低的烷基,或者R.sup.6和R.sup.7在一起形成一个含氮饱和杂环基团,与相邻的氮原子一起,其中杂环基团可以用较低的烷基或可选择的保护羟基(较低)烷基取代,前提是当R.sup.1为氰基且R.sup.6和R.sup.7分别为较低的烷基时,R.sup.2为卤素或R.sup.3为较低的烷基,以及其盐,以及制备它们的过程和包含它们的药物组合物。这些衍生物及其盐可用作抗溃疡剂和平滑肌松弛剂。
