Definitions
- the present invention relates, as new products, to the 3,4-diarylthiazolin-2-one or -2-thione derivatives of general formula (I) below and their addition salts, in particular the addition salts pharmaceutically acceptable.
- One of the biotransformation routes of arachidonic acid is the cyclooxygenase route; it allows the transformation of arachidonic acid into PGG2 and then into PGH2.
- Recent work on the cloning and sequencing of cyclooxygenase has made it possible to demonstrate in several species and in humans in particular, two isoenzymes cyclooxygenase-1 (COX-1) and cyclooxygenase 2 (COX-2).
- the first is a constitutive enzyme, expressed in most tissues, while the second which is expressed in some tissues such as the brain, is inducible in the majority of tissues by many products, in particular by cytokines and mediators produced in during the inflammatory reaction.
- Each enzyme plays a different role and the inhibition of COX-1 or COX-2 will cause consequences that are not identical. Inhibition of COX-1 will cause a decrease in prostaglandins participating in homeostasis which can lead to side effects. The inhibition of COX-2 will cause a decrease in the prostaglandins produced in an inflammation situation. Thus the selective inhibition of COX-2 makes it possible to obtain a well-tolerated anti-inflammatory agent.
- the compounds of the invention make it possible to obtain this selective inhibition. Consequently, the compounds in question have a very interesting pharmacological profile insofar as they are endowed with anti-inflammatory and analgesic properties while being remarkably well tolerated in particular at the gastric level. They will be particularly indicated for the treatment of inflammatory phenomena and for the treatment of pain. Mention may be made, for example, of their use in the treatment of arthritis, in particular rheumatoid arthritis, spondyloarthritis, gout arthritis, osteoarthritis, juvenile arthritis, autoimmune diseases, lupus erythematosus.
- bronchial asthma dysmenorrhea, tendinitis, bursitis, dermatological inflammations such as psoriasis, eczema, burns, dermatitis.

- the present invention also relates to the process for the preparation of said products and their applications in therapy.
- these known derivatives have two aryl groups in position 4 and 5, that is to say on two carbon atoms of the thiazole ring.
- thiazole derivatives very different from these known compounds: on the one hand in that they have an oxo or thioxo function in position-2, hence their name as thiazolinone or thiazoline thione, on the other hand, in that they have an aromatic ring in position-3, that is to say not on a carbon atom but on the nitrogen atom of the thiazole cycle and finally in that they have an alkylsulfonylphenyl or benzene sulfonamide group in position-4, have remarkable selective inhibitors of cyclooxygenase-2.
