The present invention provides therapeutically active compounds which are xanthine derivatives, processes for the manufacture of said derivatives, pharmaceutical formulations containing the active compounds and the use of the compounds in therapy, particularly in the treatment of diseases where under- activation of the HM74A receptor contributes to the disease or where activation of the receptor will be beneficial, having the formula (II): wherein R1 is selected from: hydrogen and C1-4 alkyl which may be optionally substituted with one or more groups selected from CN and CF3, R2 is selected from: C2-10 unsubstituted alkyl, C1-10 alkyl substituted with one or more groups selected from fluorine and CN, C5 alkenyl, unbranched C4 alkenyl, and C1-4 alkyl substituted with cycloalkyl, and R3 is selected from halogen and CN.

L'invention concerne des composés actifs sur le plan thérapeutique : des dérivés de xanthine, des procédés de fabrication des dérivés, des formulations pharmaceutiques renfermant les composés actifs et l'utilisation des composés dans un traitement, notamment le traitement de maladies dans lesquelles une sous-activation du récepteur HM74A contribue à la maladie ou l'activation du récepteur peut être bénéfique, de formule (II): dans laquelle R?1¿ est sélectionné parmi: l'hydrogène et l'alkyle en C¿1-4? éventuellement substitué par un ou plusieurs groupes sélectionnés parmi CN et CF¿3?, R?2¿ est sélectionné parmi: un alkyle non substitué en C¿2-10?, un alkyle en C¿1-10? substitué par un ou plusieurs groupes sélectionnés parmi le fluor et CN, l'alcényle en C¿5?, l'alcényle en C¿4? non ramifié et l'alkyle en C¿1-4? substitué par le cycloalkyle et R?3¿ est sélectionné parmi l'halogène et CN.
