Patent ID: 7026357

Claim:
A compound selected from those of formula (I): wherein R 1 , R 2 , R 3 and R 4 independently represent hydrogen, halogen or alkyl, alkoxy, hydroxy, alkylthio, mercapto, cyano, amino (optionally substituted by one or two alkyl), nitro, carboxy, alkoxycarbonyl, aminocarbonyl (optionally substituted by one or two alkyl) or carbamoyl, or, taken in pairs, form together with the carbon atoms to which they are bonded a phenyl ring or an aromatic heterocycle having from 5 to 6 ring members and containing from 1 to 3 hetero atoms selected from nitrogen, oxygen and sulphur, L 1 and L 2 each represents hydrogen or together form —CH 2 —CH 2 —, X 1 , attached at the 2 or 3 position of the aromatic ring, represents a bond, and in that case X 2 represents hydrogen, halogen, alkyl, alkoxy, hydroxy, nitro or cyano, or amino (optionally substituted by one or two alkyl), or, X 1 and X 2 , together with two adjacent carbon to which they are bonded in the 2, 3 or 4 position of the aromatic ring, form (C 4 –C 7 )cycloalkyl wherein one or two —CH 2 — of the cycloalkyl ring are optionally replaced by oxygen or NH (optionally substituted by alkyl) and wherein one carbon of the cycloalkyl ring is substituted by G, X 3 represents hydrogen, halogen, alkyl, alkoxy, hydroxy, nitro or cyano, or amino (optionally substituted by one or two alkyl), G represents a group selected from: wherein: the broken lines indicate the optional presence of a double bond, Alk represents linear or branched (C 1 –C 6 )alkylene wherein, when G 1 or G 2 contains imidazoline, the group Alk- is attached at the 2 position of the ring, n is 0 or 1, wherein: the term “alkyl” denotes linear or branched group containing from 1 to 6 carbon, the term “alkoxy” denotes linear or branched alkyl-oxy containing from 1 to 6 carbon, enantiomers and diastereoisomers thereof, and addition salts thereof with a pharmaceutically acceptable acid or base.
