The present invention relates to new imidazopyridine derivatives of formula I STR1 wherein: one of A, B, C and D is N and the other are CR, wherein each R independently represents hydrogen, C 1-4 alkyl, COOH or halogen; R 1 represents C 1-4 alkyl or C 3-7 cycloalkyl; Ar 1 represents phenyl or pyridyl which can be optionally substituted; V represents C 1-4 alkyl, C 3-7 cycloalkyl, aryl, aryl-(C 1-4)alkyl or a 5-or 6-membered aromatic heterocycle; the group X-Y represents C=C or CH--CR 3 ; R 3 represents hydrogen, C 1-4 alkyl or aryl-(C 1-4)alkyl; Z represents among others--CO 2 R 4,--tetrazol-5-yl,--CONHSO 2 R 4,--CONR 4 R 5,--CH 2 NHSO 2 R 4 ; R 4 and R 5 independently represent hydrogen, C 1-4 alkyl, aryl, aryl-(C 1-4) alkyl or perfluoro-(C 1-4) alkyl; W represents hydrogen, cyano, C 1-4 alkyl, C 1-4 haloalkyl, C 3-7 cycloalkyl, aryl, aryl-(C 1-4)alkyl, C 1-4 alkylsulfonyl, C 1-4 alkylsulfinyl, C 1-4 alkylthio, C 1-4 alkoxy, C 1-4 alkylcarbonyl, halogen, hydroxymethyl or C 1-4 alkoxymethyl, or W can have any of the meanings disclosed for Z. These compounds are angiotensin II antagonists.
