Definitions

  • the present invention relates to new derivatives of 1,1-dioxo-2H-1,2-benzothiazine-3-carboxamides, their preparation process and the pharmaceutical compositions containing them, as well as their use for the treatment of cartilage pathologies.
  • the anti-inflammatory drugs currently marketed for the treatment of joint pathologies such as arthritis or osteoarthritis generally have a low affinity for the target tissues and require administrations at high doses to obtain the desired therapeutic effect.
  • the new compounds, objects of the present invention retain the very strong affinity for the cartilaginous tissues already described for the derivatives of the prior art but, moreover, they have protective properties of cartilage very clearly superior to those of the compounds already described, which, given the proximity of their structures, was completely unpredictable. These properties therefore make the compounds of the invention extremely advantageous for the treatment of pathologies such as arthritis or osteoarthritis.
  • P represents a hydrogen atom or a hydroxy group, linear or branched (Ci-C 6 ) alkoxy, linear or branched acyloxy (CrC 6 ), linear or branched alkylsulfonyloxy (Ci-C 6 ), arylsulfonyloxy or arylalkoxy (-C ⁇ ) linear or branched,
  • R 2 represents a hydrogen atom or a linear or branched (-C ⁇ ) alkyl group
  • ⁇ R 3 and R identical or different, each represent a hydrogen atom, a halogen atom or a linear or branched (-C ⁇ ) alkyl group, hydroxy or alkoxy
  • ⁇ Ak represents a linear or branched alkylene chain (C ⁇ -C 6 ),
  • R 5 , R 6 and R 7 identical or different, each represent a linear or branched (-C ⁇ ) alkyl group, or else R 5 , R 6 and R 7 , taken together with the nitrogen atom who wear them, form a saturated or unsaturated nitrogen heterocycle, ⁇ X represents a halogen atom,
  • Ri represents a hydroxy group
  • R, R 5 and R ⁇ each represent a methyl group
  • R 3 and R each represent a hydrogen atom
  • Ak represents a group - (CH 2 ) -.
  • saturated or unsaturated nitrogen heterocycle is understood to mean a 5- to 7-membered, saturated or unsaturated, aromatic or non-aromatic monocyclic group containing one, two or three heteroatoms, one of these heteroatoms being the nitrogen atom, and the additional heteroatom (s) possibly present being chosen from oxygen, nitrogen or sulfur atoms, it being understood that the nitrogen heterocycle can be optionally substituted by one or more groups, identical or different, alkyl (C ⁇ -C 6 ) linear or branched.
  • the preferred nitrogen heterocycles are the pyridyl and piperidyl groups N-substituted by a linear or branched (C C ⁇ ) alkyl group.
  • the preferred compounds of formula (I) are those for which R 2 represents a linear or branched alkyl group (C ⁇ -C 6 ).
  • the preferred compounds of formula (I) are those for which X represents an iodine atom.
  • the preferred compounds of the invention are those for which R 6 and R 7 , identical or different, each represent a linear or branched (C 2 - C 6 ) alkyl group.
  • the invention also extends to a process for preparing the compounds of formula (I) characterized in that a compound of formula (H) is reacted:
  • R ' 2 -Y ! (IV) in which R ' 2 represents a linear or branched (C ⁇ -C 6 ) alkyl group, and Y ! represents a classic leaving group of organic chemistry,
  • R 13 R 2 , R 3 , R 4 are as defined above
  • Ak has the same meaning as in formula (I)
  • Z represents either a group X as defined in formula (I), or an NR'sR'e group in which R ' 5 and R' 6 , identical or different, each represent a linear or branched (Ci-C 6 ) alkyl group, or together form a saturated or unsaturated, non-aromatic nitrogen heterocycle,
  • the derivatives of the present invention have demonstrated in biological studies an enhanced tropism for the cartilage tissues. These molecules have, on the other hand, properties on the cartilage which makes them particularly useful for the treatment of pathologies such as osteoarthritis and arthritis.
  • the invention also extends to pharmaceutical compositions containing as active principle at least one compound of formula (I) with one or more inert, non-toxic and pharmaceutically acceptable vehicles.
  • pharmaceutical compositions according to the invention mention may be made more particularly of those which are suitable for oral, parenteral (intravenous or subcutaneous), nasal administration, simple or coated tablets, sublingual tablets, capsules, tablets, the suppositories, creams, ointments, dermal gels, injections, oral suspensions, etc.
  • the useful dosage is adaptable according to the nature and severity of the disease, the route of administration as well as according to the age and weight of the patient. This dosage varies from 0.5 mg to 2 g per 24 hours in one or more doses.
