Patent ID: 7947675

Claim:
A compound of formula (I): in which: R 1 and R 2 , which may be identical or different, are a (C 1 -C 6 )alkyl radical or a (C 3 -C 10 )cycloalkyl radical, or alternatively the two radicals R 1 and R 2 together form, with the nitrogen atom that bears them, a saturated heterocyclic radical of formula (II): in which: Y and Z, which may be identical or different, are C 1 , C 2 or C 3 hydrocarbon-based chains, optionally substituted by one or more radicals R 4 , which may be identical or different, selected from the group consisting of (C 1 -C 6 )alkyl and (C 3 -C 10 )cycloalkyl, X is a carbon, oxygen or sulfur atom, a group >CR 6 R 7 with R 6 and R 7 , which may be identical or different, representing OH, a group —COOAlk, Alk meaning C 1 -C 6 alkyl, a —CH 2 OH group, a substituted or unsubstituted (C 6 -C 18 )aryl radical, a substituted or unsubstituted (C 6 -C 18 )aroyl radical, a group N—R 5 with R 5 being a (C 1 -C 6 )alkyl radical, or alternatively the two radicals R 1 and R 2 together from, with the nitrogen atom that bears them, a tetrahydroisoquinolyl radical R 3 is NO 2 , NH 2 , CN, Cl or Br AR is a substituted or unsubstituted (C 6 -C 18 )aryl radical of formula (III): in which R 8 , R 9 , R 10 , R 11 and R 12 , which may be identical or different, are selected from the group consisting of a hydrogen atom, a halogen atom, a branched or unbranched (C 1 -C 10 )alkyl radical, a substituted or unsubstituted aryl radical, a CN radical and a trifluoromethyl group, or alternatively R 8 and R 9 or R 9 and R 10 or R 10 and R 11 or R 11 and R 12 together form a chain —(CH 2 ) p with p=1-5, an optical isomer, oxide form thereof, or a pharmaceutically acceptable addition salt thereof with an acid or base.
