- Tetrazole amide derivatives of heterocyclic alkenyl acid and their use as antiallergic substances
-
Tetrazole amide derivatives of heterocyclic alkenyl acids, of general formula STR1 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, CH2 OCOCH3, 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. Such derivatives possess high antiallergic activity.
