  • Patent number: 8372878
    Abstract: There are described compounds of general formula (I) and isomeric forms thereof wherein n is 0, 1, 2 or 3, saturated or unsaturated; most preferably at least one of R1 to R5 represents halogen; at least one of R1, R2, R3, R4 and R5 is selected from —S—R or —COOR, or two or more Of R1-R5 comprise a linking group such as —S—(CH2)mS—, where m is 1, 2 or 3 and R is selected from alkyl having 1 to 5 carbon atoms, cycloalkyl having 3-6 carbon atoms, hydroxy, and aryl having 6 to 10 carbon atoms, such groups being optionally substituted, and when R1 is selected from —S—R, then at least one of R2, R3 and R5 is most preferably selected from halogen; and R1, R2, R3, R4 and R5 are otherwise the same or different and are selected from hydrogen, halogen, alkyl having 1 to 5 carbon atoms, electron donor groups such as alkoxy having 1-5 carbon atoms or hydroxy, electron acceptor groups selected from cyano, nitro, trifluoroalkyl or amide; alkylamino, benzoyloxy, nitroxy, phenyl or sulpho; and pharmacologically acceptable sal

  • Patent number: 8227502
    Abstract: There are described Compounds of formula (I) in which R3 to R8 are independently selected from hydrogen, halogen, trihaloalkyl, alkyl having 1, 2, 3, 4 or 5 carbon atoms, electron donor groups selected from alkoxy having 1, 2, 3, 4 or 5 carbon atoms, trihaloalkoxy, hydroxy or amino, electron acceptor groups selected from cyano, sulphonic, nitro, or amide; R1 is an optionally substituted phenyl, benzyl or cyclohexyl group; R2 is selected from amino, substituted amino or guanidino groups, Z is a saturated or unsaturated C1-5 hydrocarbon chain, and salts thereof. A process for their preparation and compositions containing them are also described. The Compounds are either agonists or antagonists of a specific adenosine receptor or a number of adenosine receptors and have usefulness for the treatment of inflammation, arthritic conditions, rheumatoid arthritis, osteoarthritis, mental disorders, or for inducing central nerve regeneration.
