Abstract
This 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. ##STR1## wherein R.sup.1 represents phenyl optionally substituted by one or more substituents selected from halogen, C.sub.1-3 alkyl, trifluoromethyl, nitro, cyano, --CO.sub.2 R.sup.a.sub.1 --CONR.sup.a R.sup.b, --COR.sup.a, --SOR.sup.c, --SO.sub.2 R.sup.c, --SO.sub.3 H, --SO.sub.2 NR.sup.a R.sup.b, --OR.sup.a, --NHSO.sub.2 R.sup.c, --NHCOR.sup.a and --NR.sup.a R.sup.b, PA1 R.sup.2 represents a C.sub.1-6 alkyl or C.sub.3-6 alkenyl group; R.sup.3 represents C.sub.1-3 alkyl; PA1 R.sup.a and R.sup.b may each independently represent hydrogen or C.sub.1-3 alkyl or, when --NR.sup.a R.sup.b is directly attached to said phenyl, R.sup.a and R.sup.b 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 C.sub.1-3 alkyl; PA1 R.sup.c represent…
