The present invention relates to new 1,3-dioxolan-2-yl derivatives of 2-picolylamine having the formula (I):
wherein:
R₁ represents an alkyl radical; R₂ represents hydrogen, or a C(=O)R₄ group, wherein R₄ represents C₁-C₆-alkyl or C₁-C₆-alxoxide; X is a single bond, or a -O-, -C(=O)O-, -OC(=O)C-, or -NR₅C(=O)O- group, wherein R₅ is H, C₁-C₄ alkyl or C₁-C₄ acyl; q is 0 or 1; t is (+) when q=1, and t has no meaning when q=0; R₃ is H or C₁-C₆ alkyl when q=1 and an electron pair when q=0; A⁻ is a pharmaceutically acceptable anion. The invention also relates to a procedure for their preparation and to pharmaceutical compositions containing them. These compounds are antagonists of PAF and, thus, useful for the treatment of the diseases in which this substance is involved.
本发明涉及新的2-吡啶基氨基甲酸酯的1,3-二氧杂环己烷-2-基衍生物,其化学式为(I):其中:R₁代表烷基基团;R₂代表氢或C(=O)R₄基团,其中R₄代表C₁-C₆烷基或C₁-C₆氧化物基;X是单键,或-O-,-C(=O)O-,-OC(=O)C-或-NR₅C(=O)O-基团,其中R₅为H,C₁-C₄烷基或C₁-C₄酰基;q为0或1;当q=1时,t为(+),当q=0时,t无意义;R₃为H或C₁-C₆烷基,当q=1时为电子对;A⁻为药学上可接受的阴离子。本发明还涉及它们的制备方法和含有它们的制药组合物。这些化合物是PAF拮抗剂,因此,对于涉及此物质的疾病的治疗是有用的。
