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 2-
环戊胺的
1,3-二氧戊环-4-基新衍
生物: 其中: R₁ 代表烷基或
苯基烷基;R₂ 代表
氢、C₁-C₄-酰基或 C₁-C₄- 烷
氧基羰基; R₃ 是电子对,在这种情况下,t 表示无,q 为零,或者 R₃ 是
氢或 C₁-C₄ 烷基,在这种情况下,t 为 (+),q=1;X 是单键、
氧原子或
氨基甲酰
氧基;A- 是药学上可接受的阴离子。 这些化合物是 PAF
拮抗剂,因此可用于治疗与 PAF 有关的疾病。
