Compound of general formula (I) in racemic, enantiomeric form or any combination of these forms and in which R1 and R2 independently represent a halogen atom or an alkyl, haloalkyl, alkoxy, cyano, nitro, amino, alkylamino dialkylamino, -NR8-CO-R5, -NR 8 SO 2 R 5, -NR 8 CO- (CH2) n-NR6R7, -NR8-SO2- (CH2) n -CO-NH2 NR6R7o; n represents an integer chosen from 0, 1, 2, 3, 4, 5 and 6; R5 represents an alkyl, aryl or heteroaryl; R6 and R7 independently represent a hydrogen atom, an alkyl radical or an alkyloxycarbonyl; R8 represents a hydrogen atom or an alkyl radical; R3 represents an alkyl radical or a hydrogen atom; or the two radicals R 3 form together with the atom to which decarbono are attached, a cycloalkyl radical comprising 3 to 6 members; R4 represents a haloalkyl radical of 2 to 10 carbon atoms; Y represents an alkylene chain of 2 to 14 carbon atoms, straight or branched, it being possible for this cadenasaturada or unsaturated, and may contain one or more additional members -O-; X represents -S-, -SO-, -SO2-, -S> = N (R9) - or -S (O)> = N (R9) -; R9 represents a hydrogen atom or haloalkylcarbonyl radical, or a salt pharmaceutically acceptable latter.
