Patent ID: 7223758

Claim:
A compound of formula (I): wherein: R 1 is hydrocen, linear or branched alkyl containing from 1 to 6 carbon atoms, —COR or —COOR, wherein R is chosen from: linear or branched alkyl containing from 1 to 6 carbon atoms, optionally substituted with pyridyl or carbamoyl, linear or branched —CH 2 -alkenyl containing in total from 3 to 9 carbon atoms, or aryl containing from 6 to 10 carbon atoms or aralkyl containing from 7 to 11 carbon atoms, wherein the arly and aralkyl are independently optionally substituted with OH, NH 2 , NO 2 , linear or branched alkyl containing from 1 to 6 carbon atoms, linear or branched alkoxy containing from 1 to 6 carbon atoms, or 1 to 3 halogen atoms, R 2 is a group corresponding to formula (II) below: wherein n is 0, 1, 2 or 3; a double bond possibly being present when n is 2 or 3; X is one of the following groups: saturated or unsaturated monocyclic or bicyclic heterocyclic group; aryl containing from 6 to 10 carbon atoms or aralkyl containing from 7 to 11 carbon atoms, wherein the aryl and aralkyl are independently optionally substituted with OH, NH 2 , NO 2 , linear or branched alkyl containing from 1 to 6 carbon atoms, linear or branched alkoxy containing from 1 to 6 carbon atoms, or 1 to 3 halogen atoms; —NR 4 R 5 , wherein R 4 is linear or branched alkyl containing from 1 to 6 carbon atoms, —COR, —CONHR, —CSNHR or —SO 2 R, R having the meaning given above, and R 5 is hydrogen or linear or branched alkyl containing from 1 to 6 carbon atoms; or —COR, R having the meaning given above, R 3 is —Y—(CH 2 ) m —C(CN)R 6 R 7 , wherein: Y is oxygen or —N(R 8 )—, R 8 is hydrogen or linear or branched alkyl containing from 1 to 6 carbon atoms, m is 0, 1, 2 or 3, R 6 is hydrogen, linear or branched alkyl containing from 1 to 6 carbon atoms, aryl or aralkyl group, wherein the aryl and aralkyl are independently optionally substituted with OH, NH 2 , NO 2 , linear or branched alkyl containing from 1 to 6 carbon atoms, linear or branched alkoxy containing from 1 to 6 carbon atoms, or aryloxy of 7 to 11 carbon atoms, wherein the aryloxy is optionally substituted with 1 to 3 halogen atoms; and R 7 is hydrogen or linear or branched alkyl containing from 1 to 6 carbon atoms, or R 6 and R 7 taken together with the carbon to which they are attached form cyclohexyl, or a racemic, enantiomeric or diastereoisomeric form thereof; or an addition salt thereof.
