Tetrazole amide derivatives of heterocyclic alkenyl acids, of general formula (I):
in which
Y = NH, O or S when m = 1;
Y = N when m = 2;
m = 1 or 2;
l = 0 or 4;
R = H, C₁₋₄ alkyl, Cl, Br, CF₃, CH₂OCOCH₃, or OCH₂-Ph;
R₁ = H, alkaline metal or alkaline earth metal;
the double bond of the alkenyl chain being of trans or cis configuration and the possible benzene ring being unsubstituted or substituted.
Said derivatives possess high antiallergic activity.
杂环烯烃酸的四唑酰胺衍生物,一般式(I)如下:其中Y = NH、O或S,当m = 1 时;Y = N,当m = 2 时;m = 1 或 2;l = 0 或 4;R = H、C₁₋₄烷基、Cl、Br、CF₃、CH₂OCOCH₃或OCH₂-Ph;R₁ = H、碱金属或碱土金属;烯烃链的双键为顺式或反式构型,可能的苯环未取代或取代。这些衍生物具有很高的抗过敏活性。
