Compounds of general formula I (Z=O) are prepared by reacting 4-piperidinealkanamines with carboxylic acids or reactive derivatives thereof, such as the esters of lower aliphatic alcohols or acid halides. Compounds of general formula I (Z=CONH) are likewise obtained by means of the reaction between 4-piperidinealcanamines and isocyanates.
The compounds of general formula I thus obtained, and the pharmaceutically acceptable salts thereof are of a great therapeutic utility, given their activity as specific antagonists of histamine H₁ receptors.
通式I(Z=O)的化合物是通过将4-
哌啶烷基胺与
羧酸或其反应衍
生物(如低碳醇酯或酸卤化物)反应制备而成的。通式I(Z=CONH)的化合物同样是通过4-
哌啶烷胺和
异氰酸酯之间的反应获得的。这样获得的通式I的化合物及其药用可接受的盐在治疗上具有极大的用途,因为它们作为
组织胺H₁受体的特异拮抗剂而具有活性。
