Claim:
An N-phenylacetamide compound having formula (I): in which: R is a hydrogen atom, a (C 1 -C 6 )alkyl radical, a —CH 2 —NR a R b radical, a —C(O)—NR a R b radical, or a —C(S)—NR a R b radical, wherein R a is a hydrogen atom, or a (C 1 -C 4 )alkyl radical, and R b is a hydrogen atom, a phenyl, or a cycloalkyl radical; R 1 is a (C 1 -C 6 )alkyl radical; R 2 is a hydrogen, chlorine, fluorine, or bromine atom, or a (C 1 -C 6 )alkyl radical; R 3 is a hydrogen atom, or a —C(O)R 7 radical, wherein R 7 is a (C 1 -C 6 )alkyl, or (C 1 -C 6 )alkoxy radical; or else R 3 is bonded to R 6 , and —R 3 -R 6 — is —C(O)—, —C(O)CH 2 —, —SO 2 —, or —CH 2 —; R 4 and R′ 4 are identical and are each a (C 1 -C 6 )alkyl radical; or else, R 4 and R′ 4 are bonded to one another and form, together with the carbon atom from which they depend, a cycloalkyl group; R 5 is a group selected from among: (i) an unsubstituted phenyl radical, or a phenyl radical substituted by one, two, or three identical or different substituents selected from among the atoms fluorine, chlorine, iodine, or bromine, or the radicals (C 1 -C 6 )alkyl, hydroxymethyl, monofluoromethyl, difluoromethyl, trifluoromethyl, hydroxyl, phenyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, (C 1 -C 6 )alkoxy, phenoxy, benzyloxy, monofluoromethoxy, difluoromethoxy, or trifluoromethoxy; (ii) a (C 1 -C 12 )alkyl radical, optionally substituted by one or more hydroxyl groups, or one or more fluorine, chlorine, iodine, or bromine atoms; (iii) a cycloalkyl radical, or a —(CH 2 ) m -cycloalkyl radical in which m is equal to 1, 2, or 3; or, (iv) an aralkyl radical —(CH 2 ) n —Ar with n equal to 1, 2, or 3, and Ar is an unsubstituted phenyl radical, unsubstituted naphthyl, or a phenyl radical substituted by one to three identical or different substituents selected from among the atoms fluorine, chlorine, iodine, or bromine, or the radicals (C 1 -C 6 )alkyl, hydroxymethyl, monofluoromethyl, difluoromethyl, trifluoromethyl, hydroxyl, phenyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, (C 1 -C 6 )alkoxy, phenoxy, benzyloxy, monofluoromethoxy, difluoromethoxy, or trifluoromethoxy; with the proviso that when R 3 is bonded to R 6 and —R 3 -R 6 — is —C(O)CH 2 —, then R 5 is different from a benzyl radical or a group comprising from 4 to 12 carbon atoms of formula —CH 2 —CH(OH)—(CH 2 ) p -alkyl in which p is an integer of from 1 and 9, and the alkyl radical can optionally be substituted by one or more hydroxyl groups, or one or more fluorine, chlorine, iodine, or bromine atoms; R 6 is a hydrogen atom, or else R 6 is bonded to R 3 , and —R 3 -R 6 — is —C(O)—, —C(O)CH 2 —, —SO 2 —, or —CH 2 —; and the pharmaceutically acceptable salts, conformers, and rotamers thereof.
