Novel 2-cyclic amino-2-(1,2-benzisoxazol-3-yl)acetic acid derivatives of the formula: ##STR1## wherein R.sub.1 is hydrogen or a halogen atom, R.sub.2 is a lower alkyl group, Am is a 5- to 9-membered saturated cyclic amino group which may be substituted by a lower alkyl group, and the group: ##STR2## binds to the piperidine moiety at 3- or 4-position of the latter, and their pharmaceutically acceptable acid addition salts and quaternary ammonium salts, process for their preparation, and pharmaceutical compositions containing these compounds. They have potent anticholinergic antispasmodic activity, while they are weak in side effects such as mydriasis, inhibition of salivary secretion and tachycardia.
2-环氨基-2-(1,2-苯并异噁唑-3-基)乙酸衍生物的化学式为:##STR1##其中R.sub.1是氢或卤素原子,R.sub.2是较低的烷基基团,Am是一个5-至9-成员饱和环氨基基团,可能被较低的烷基基团取代,以及该基团:##STR2##与哌啶基团在后者的3-或4-位置结合,以及它们的药学上可接受的酸加盐和季铵盐,它们的制备方法,以及含有这些化合物的药物组合物。它们具有强效的抗胆碱能抗痉挛活性,同时在瞳孔扩大、唾液分泌抑制和心动过速等副作用方面效果较弱。
