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.
