  4-Substituted 2-alkoxytetrahydrofurans as potent and long-lasting PAF antagonists

  摘要：

  A series of 4-substituted 2-alkoxytetrahydrofuran derivatives featuring an acetal group were prepared and evaluated for PAF antagonist activity in the PAF-induced in vitro platelet-aggregation and in vivo hypotension tests. Compound 2-[[N-acetyl-N-[[[2-(octadecyloxy)tetrahydrofuran-4-yl]methoxy]carbonyl]amino]methyl]1-ethylpyridinium chloride (4e, UR-11353) was selected for further development on the basis of its high activity and long-lasting action. The compound maintained a significant activity even 24 h after administration of a single dose of 1 mg/kg iv in the PAF-induced mortality test in mice and 10 h after administration of the same dose in the PAF-induced hypotension test in rats. Comparison with previously reported carba analogues suggests that the presence of the acetal group is the structural characteristic that confers its long-lasting activity.

  The present invention describes a process to obtain 4-substituted 2-­alkoxytetrahydrofuran derivatives of formula I. wherein, -R₁ represents an alkyl or phenylalkyl radical; -R₂ is 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;.A⁻ is a pharmaceutically acceptable anion. These compounds are antagonists of PAF and, therefore, useful for the treatment of the diseases in which this substance is involved

  本发明描述了一种获得式 I 的 4-取代的 2-烷氧基四氢呋喃衍生物的工艺。 其中 -R₁代表烷基或苯基烷基； -R₂是氢、C₁-C₄-酰基或 C₁-C₄-烷氧基羰基；-R₃或者是电子对，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；。A- 是药学上可接受的阴离子。这些化合物是 PAF 的拮抗剂，因此可用于治疗与 PAF 有关的疾病。
