Abstract:
1. A compound of formula (I): wherein: R represents hydrogen or is selected from the values of R2 and R3, R1 represents alkenyl or alkyl substituted with —CO—NR7R8, —NR7R8, hydroxyl, or a halogen atom, R2 and R3, which may be identical or different, represent alkyl or —O—alkyl optionally substituted with —CO—NR7R8, —NR7R8, alkoxy, alkoxy-NR7R8, free or esterified carboxyl, or phenyl, which is itself optionally substituted, R4, R5 and R6, which may be identical or different, are selected from a hydrogen atom, a halogen atom and cyano, amino, and optionally substituted alkoxy or alkyl radicals, R4 also being selected from the group consisting of carboxaldehyde —CH═O, formaldoxime —CH═N—OH and methylhydroxylamine —CH2NHOH; R7 and R8, which may be identical or different, are selected from hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, aryl and heteroaryl, which may be monocyclic or bicyclic, all these radicals being optionally substituted, or alternatively R7 and R8 form, with the nitrogen atom to which they are attached, an unsaturated or partially or totally saturated 3- to 10-membered heterocyclic radical containing one or more hetero atoms selected from O, S, N and NR14, this radical being optionally substituted, all the above alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, aryl and heteroaryl radicals, which may be monocyclic or bicyclic, and also the heterocyclic radical formed by R7 and R8 with the nitrogen atom to which they are attached, being optionally substituted with one or more radicals, which may be identical or different, selected from a halogen atom and cyano, hydroxyl, alkyl, alkoxy, alkylthio, nitro, oxo, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylalkyl, heterocycloalkylalkyl, arylalkyl, heteroarylalkyl, —C(═O)—R9, —C(═O)—OR10, —N(R11)—C(═O)—R9, —N(R11)—C(═O)—OR10, —NR12R13, —C(═O)—NR12R13, —N(R11)—C(═O)—NR12R13, —S(O)n—R9, —N(R11)—S(O)n—R9, —S(O)n—NR12R13 and —N(R1 1)—S(O)n—NR12R13 radicals, n represents an integer from 0 to 2, the latter alkyl, alkoxy, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylalkyl, heterocycloalkylalkyl, arylalkyl and heteroarylalkyl radicals themselves being optionally substituted with one or more radicals, which may be identical or different, selected from a halogen atom and hydroxyl, alkyl, alkoxy, —NR12R13, free or esterified carboxyl, CF3, nitro, cyano, phenyl and phenylalkyl radicals in which the phenyl radical is itself optionally substituted with one or more radicals, which may be identical or different, selected from a halogen atom and hydroxyl, alkyl, alkoxy, free or esterified carboxyl, CF3, nitro, cyano and pyridyl radicals; R9 represents alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylalkyl, heterocycloalkylalkyl, arylalkyl or heteroarylalkyl, all these radicals being optionally substituted, R10 represents the values of R9 or hydrogen, R11 represents hydrogen or optionally substituted alkyl, R12 and R13, which may be identical or different, represent hydrogen, acyl, alkyl, cycloalkyl, heterocycloalkyl, heteroaryl, SO2-heteroaryl, —SO2-alkyl, —SO2-phenyl, —CO—NH-phenyl and phenyl radicals, all these radicals being optionally substituted, or alternatively R12 and R13 form, with the nitrogen atom to which they are attached, an unsaturated or partially or totally saturated 3- to 10-membered heterocyclic radical containing one or more hetero atoms selected from O, S, N and NR14, this radical being optionally substituted, R14 represents the values of R9, hydrogen, acyl or free or esterified carboxyl, the radicals R9, R10, R11, R12, R13 and R14 above, and also the cyclic radical that may be formed by R12 and R13 with the nitrogen atom to which they are attached, being optionally substituted with one or more radicals, which may be identical or different, selected from a halogen atom and alkyl, alkyl-NH2, alkyl-NHCO2alkyl, NH2, NHCO2alkyl, hydroxyl, alkoxy, hydroxyalkoxy, free or esterified carboxyl, CF3, SCF3, OCF3, OCHF2, SO2CF3, nitro, cyano, heterocycloalkyl, heteroaryl and phenyl radicals, the latter cyclic radicals themselves being optionally substituted with one or more radicals, which may be identical or different, selected from a halogen atom and alkyl, hydroxyl, alkoxy, free or esterified carboxyl, CF3, SCF3, OCF3, OCHF2, SO2CF3, NH2, NHCO2alkyl, nitro and cyano radicals, all the above aryl, heteroaryl and heterocycloalkyl radicals being, in addition, optionally substituted with an alkylenedioxy radical, all the above alkyl, alkenyl, alkoxy or —O-alkyl and alkylthio radicals being linear or branched and containing no more than 6 carbon atoms, all the above cycloalkyl radicals containing no more than 7 carbon atoms, all the above aryl, heteroaryl and heterocycloalkyl radicals containing no more than 10 carbon atoms; or a stereoisomer, a racemate, an enantiomer or a diastereoisomer of said compound of formula (I), or a pharmaceutically acceptable addition salt of said compound of formula (I) with a mineral or organic acid or a mineral or organic base.
