Claim:
An imidazolone derivative, characterized in that said derivative corresponds to formula (I) in which: R 1 represents a C 1 -C 3 alkyl radical or a hydrogen atom, and/or an aryl radical Ar 1 is chosen from R represents an R 2 —S— group, R 2 then being chosen from radicals represented by T 1 -(CH 2 ) n , with n=0, 1, 2 or 3 and T 1 representing one of the following radicals: methyl, vinyl, alkyl, alkynyl, nitrile, cycloalkyl, which may be C 3 or C 4 , Z—O, Z—CO, with Z═C 1 -C 3 alkyl, or hal, hal representing F, Cl, Br or I or a CCl 3 group, or an R 3 —NH— group, R 3 then being chosen from radicals represented by T 2 -(CH 2 ) n , with n=0, 1 or 2, and T 2 representing one of the following radicals: methyl, vinyl, ZO, ZO—CONH—, —CH—(OZ) 2 , ZCO, with Z═H or linear or branched C 1 -C 4 alkyl, NH 2 , C 3 cycloalkyl, aryl or substituted aryl, or R 2 ═H, or an R 4 —CONH— group, R 4 then being a branched C 3 -C 5 alkyl radical, or Ar 2 or Ar 2 —S, Ar 2 being chosen from a phenyl, substituted phenyl or benzodioxolyl radical, and an IC 50 of less than 5 μM.
