Pyrazole derivatives as angiotensin II antagonists

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.sub.1-4 alkyl, COOH or halogen; R.sub.1 represents C.sub.1-4 alkyl or C.sub.3-7 cycloalkyl; Ar.sub.1 represents phenyl or pyridyl which can be optionally substituted; V represents C.sub.1-4 alkyl, C.sub.3-7 cycloalkyl, aryl, aryl-(C.sub.1-4)alkyl or a 5- or 6-membered aromatic heterocycle; the group X-Y represents C.dbd.C or CH--CR.sub.3 ; R.sub.3 represents hydrogen, C.sub.1-4 alkyl or aryl-(C.sub.1-4)alkyl; Z represents among others --CO.sub.2 R.sub.4, --tetrazol-5-yl, --CONHSO.sub.2 R.sub.4, --CONR.sub.4 R.sub.5,--CH.sub.2 NHSO.sub.2 R.sub.4 ; R.sub.4 and R.sub.5 independently represent hydrogen, C.sub.1-4 alkyl, aryl, aryl-(C.sub.1-4)alkyl or perfluoro-(C.sub.1-4)alkyl; W represents hydrogen, cyano, C.sub.1-4 alkyl, C.sub.1-4 haloalkyl, C.sub.3-7 cycloalkyl, aryl, aryl-(C.sub.1-4)alkyl, C.sub.1-4 alkylsulfonyl, C.sub.1-4 alkylsulfinyl, C.sub.1-4 alkylthio, C.sub.1-4 alkoxy, C.sub.1-4 alkylcarbonyl, halogen, hydroxymethyl or C.sub.1-4 alkoxymethyl, or W can have any of the meanings disclosed for Z. These compounds are angiotensin II antagonists.

Imidazopyridine derivatives as angiotensin II antagonists

The present invention relates to new tetralones having formula I: ##STR1## wherein R.sup.1 to R.sup.7 are as defined in claim 1. The invention also relates to processes for their preparation, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments. These compounds are antihypertensive and bronchodilator agents.

Tetralones with pharmacological activity, compositions containing them

The present invention relates to new tetralones having the formula I: ##STR1## wherein: R.sup.1 and R.sup.2 represent hydrogen, halogen, cyano, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, trifluoromethyl, pentafluoroethyl, ethynyl, trimethylsilylethynyl, C.sub.1-4 alkylcarbonylamino being the amino optionally substituted by a C.sub.1-4 alkyl group; R.sup.3 is hydrogen or C.sub.1-4 alkyl, and R.sup.4 is C.sub.1-4 alkyl, or R.sup.3 and R.sup.4 together form a C.sub.2-5 polymethylene chain; either R.sup.5 represents hydroxyl, acetoxy or formyloxy and R.sup.6 and R.sup.7 are both hydrogen, or R.sup.5 together with R.sup.6 form a carbonyl group and R.sup.7 is hydrogen, or R.sup.5 and R.sup.7 together form a bond and R.sup.6 is hydrogen; R.sup.8 is, among others, 1,2-dihydro-2-oxo-1-pyridyl, 2,3-dihydro-1-oxo-1H-isoindol-2-yl, 2-oxo-1-pyrrolidinyl, 2-oxo-1-pyperidinyl. The invention also relates to a procedure for their preparation and to pharmaceutical compositions containing them. These compounds are antihypertensive and bronchodilator agents.
