The present invention relates to new 1,3-dioxolan-4-yl derivatives of 2-picolylamine having the formula (I):
wherein:
R₁ represents an alkyl or phenylalkyl radical; R₂ represents hydrogen, C₁-C₄-acyl or C₁-C₄-alkoxycarbonyl; R₃ is either an electron pair, in which case t means nothing and q is zero, or R₃ is hydrogen or C₁-C₄-alkyl, in which case t is (+) and q=1; X is a single bond, an oxygen atom or a carbamoyloxy group; A⁻ is a pharmaceutically acceptable anion. These compounds are PAF antagonists and, consequently, useful in the treatment of the diseases in which this substance is involved.
本发明涉及具有式(I)的新型2-哌啶甲胺的1,3-二氧杂环戊烷-4-基衍生物:其中:R₁代表烷基或苯基烷基基团;R₂代表氢、C₁-C₄酰基或C₁-C₄烷氧羰基;R₃是电子对,此时t表示无意义,q为零,或者R₃是氢或C₁-C₄烷基,此时t为(+),q=1;X是单键、氧原子或氨基甲酰氧基团;A⁻是药学上可接受的阴离子。这些化合物是PAF拮抗剂,因此在治疗与该物质有关的疾病方面有用。
