Date Nov. 20, 1997This invention relates to novel adenosine derivatives, to processes for their preparation, to pharmaceutical compositions containing them and to their use in medicine. Thus the invention provides compounds of formula (I) which are agonists at the adenosine A1 receptor. wherein R1 represents phenyl optionally substituted by one or more substituents selected from halogen, C1-3alkyl, trifluoromethyl, nitro, cyano, -CO2Ra1-CONRaRb, -CORa, -SORc, -SO2Rc, -SO3H, -SO2NRaRb, -ORa, -NHSO2Rc, -NHCORa and -NRaRb, R2 represents a C1-6alkyl or C3-6alkenyl group; R3 represents C1-3alkyl; Ra and Rb may each independently represent hydrogen or C1-3alkyl or, when -NRaRb is directly attached to said phenyl, Ra and Rb together with the nitrogen atom may form a -5 or -6 or membered heterocyclic ring optionally containing a second heteroatom selected from oxygen or nitrogen, which second nitrogen heteroatom may optionally be further substituted by hydrogen or C1-3alkyl; Rc represents C1-3alkyl; and salts and solvates thereof, in particular physiologically acceptable salts and solvates thereof.
