Abstract

Abstract Compounds of the formula ##SPC1## Wherein Ar denotes an optionally substituted phenyl group or hetero-aromatic group with 5 or 6 ring members wherein the atom directly bonded to the quinoline ring is a carbon atom, R 1 represents hydrogen, halogen, lower alkyl, lower alkoxy or trifluoromethyl and R 2 and R 3 independently of one another denote hydrogen or a lower alkyl group, esters and amides of these carboxylic acids or salts of such compounds, have anti-inflammatory and analgesic activity; they are active ingredients of pharmaceutical compositions and can be used for the relief and removal of pain as well as for the treatment of rheumatic, arthritic and other inflammatory complaints; an illustrative example is α-methyl-2-(2-thienyl)-6-quinolineacetic acid.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 116 words
An anti-inflammatory or analgesic pharmaceutical composition comprising an anti-inflammatory or analgesically effective amount of a compound corresponding to the formula ##SPC7## wherein Ar denotes phenyl, thienyl or phenyl substituted by one or two identical members selected from lower alkyl, lower alkoxy, fluoro, chloro, bromo, trifluoromethyl, amino, di-lower alkyl amino, or hydroxy, R 1 represents hydrogen, fluoro, chloro, bromo, lower alkyl, lower alkoxy or trifluoromethyl and R 2 and R 3 independently of one another denote hydrogen or lower alkyl and Z is OH, NH 2 , OR, NHR, NRR or NHOH, where R is lower alkyl in which "lower" defines one to seven carbon atoms, or a pharmaceutically acceptable non-toxic salt thereof and a pharmaceutical carrier.
Claim 2
Dependent Claim 116 words
An anti-inflammatory or analgesic pharmaceutical composition comprising an anti-inflammatory or analgesically effective amount of a compound corresponding to the formula ##SPC7## wherein Ar denotes phenyl, thienyl or phenyl substituted by one or two identical members selected from lower alkyl, lower alkoxy, fluoro, chloro, bromo, trifluoromethyl, amino, di-lower alkyl amino, or hydroxy, R 1 represents hydrogen, fluoro, chloro, bromo, lower alkyl, lower alkoxy or trifluoromethyl and R 2 and R 3 independently of one another denote hydrogen or lower alkyl and Z is OH, NH 2 , OR, NHR, NRR or NHOH, where R is lower alkyl in which "lower" defines one to seven carbon atoms, or a pharmaceutically acceptable non-toxic salt thereof and a pharmaceutical carrier.
Claim 3
Dependent Claim 120 words
A composition as claimed in claim 1, in which effective compound Ar denotes phenyl, thienyl or phenyl substituted by one or two identical members selected from alkyl or alkoxy with at most 4 carbon atoms, fluorine, chlorine, bromine or trifluoromethyl, R 1 denotes hydrogen or chlorine, R 2 and R 3 independently of one another denote hydrogen or alkyl with at most 4 carbon atoms, and Z is OH, OR, NH 2 or NHOH where R is alkyl with at most 4 carbon atoms, and wherein one of the groups --CH(R 3 ) COOZ and R 1 occupies the 6-position and the other the 8-position and the group R 2 occupies the 4-position, or a pharmaceutically acceptable non-toxic salt thereof.
Claim 4
Dependent Claim 69 words
A composition as claimed in claim 1, in which effective compound Ar denotes a phenyl, thienyl or phenyl substituted by one fluorine, chlorine, methyl, methoxy or trifluoromethyl, R 1 denotes hydrogen, R 2 denotes hydrogen or methyl in the 4-position, R 3 denotes hydrogen or methyl, and Z denotes OH or methoxy, and wherein the --CH(R 3 )COOZ group occupies the 6-position, or a pharmaceutically acceptable non-toxic salt thereof.
