Claim:
A compound of the general formula I wherein R 1 independently represents one or more, same or different substituents selected from the group consisting of hydrogen, halogen, hydroxy, mercapto, trifluoromethyl, amino, (C 1 -C 3 )alkyl, (C 2 -C 3 )olefinic group, (C 1 -C 3 )alkoxy, (C 1 -C 3 )alkylthio, (C 1 -C 6 )alkylamino, (C 1 -C 3 )alkoxycarbonyl, cyano, carbamoyl, nitro or phenyl, provided that when R 1 represents one substituent, it is in the ortho position, and when R 1 represents more than one substituent, at least one R 1 substituent is in the ortho position; R 2 represents one substituent in the ortho position, said substituent being selected from the group consisting of hydrogen, halogen, hydroxy, mercapto, trifluoromethyl, amino, (C 1 -C 3 )alkyl, (C 2 -C 3 )olefinic group, (C 1 -C 3 )alkoxy, (C 1 -C 3 )alkylthio, (C 1 -C 6 )alkylamino, (C 1 -C 3 )alkoxycarbonyl, cyano, carbamoyl, nitro or phenyl; and R 3 independently represents one or more, same or different substituents selected from the group consisting of hydrogen, halogen, hydroxy, mercapto, trifluoromethyl, amino, (C 1 -C 3 )alkyl, (C 2 -C 3 )olefinic group, (C 1 -C 3 )alkoxy, (C 1 -C 3 )alkylthio, (C 1 -C 6 )alkylamino, (C 1 -C 3 )alkoxycarbonyl, cyano, carbamoyl, phenyl or carboxy; R 4 represents hydrogen, (C 1 -C 3 )alkyl, or allyl; Q represents a bond, or —C(R 6 )(R 7 )(—O—C═O)—, in which formula R 6 and R 7 independently represent hydrogen, trifluoromethyl, or (C 1 -C 4 )alkyl; Y represents either (C 5 -C 15 )alkyl, (C 2 -C 15 )olefinic group, (C 3 -C 10 )monocyclic hydrocarbon, or phenyl, any of which may be optionally substituted with one or more, same or different substituents represented by the formula R 5 ; or (C 1 -C 4 )alkyl substituted with at least one or more substituents with the formula R 5 ; or Y represents a group of formula —CH 2 —(Z—O) n —Z where Z is a (C 1 -C 3 )alkyl, where n is a integer>1 and no continuous linear sequence of atoms in the group Y>15; R 5 represents halogen, hydroxy, mercapto, trifluoromethyl, amino, (C 1 -C 3 )alkoxy, (C 1 -C 3 )alkylthio, (C 1 -C 6 )alkylamino, (C 1 -C 3 )alkoxycarbonyl, cyano, azido, nitro, —COOH, —CONH 2 , —CONHR′, or —COONR′R′ wherein R′ stands for (C 1 -C 3 )alkyl; X represents oxygen or sulphur, or a pharmaceutically acceptable salt thereof, or a hydrate or solvate thereof.
