The compounds of the formula I
wherein R, R3 and R5 independently represent hydrogen or hydroxy provided that at least one of R, R3 and R5 represents hydroxy; R1 represents hydrogen, lower alkyl, C3-C7alkenyl, hydroxy-lower alkyl, C3-C6cycloalkyl, C3-C6cycloalkyl-lower alkyl, 2-norbornyl, 2-norbornyl-lower alkyl, aryl, aryl-lower alkyl, aryl-C3-C6cycloalkyl, 9-fluorenyl or 9-fluorenyl-lower alkyl; or R1 represents a bicyclic benzo-fused 5 or 6-membered saturated carbocyclic radical or a benzo fused 5 or 6-membered saturated heterocyclic radical containing a heteroatom selected from oxygen and sulfur directly attached to the fused benzene ring, any said bicyclic radicals being optionally substituted on the benzo portion by lower alkyl, lower alkoxy or halogen; R2 represents hydrogen, halogen, -SR1 or -N(R9)R1 in each of which R1 has meaning as defined hereinbefore provided that R1 in -SR1 does not represent hydrogen; R9 represents hydrogen or lower alkyl; R4 represents hydroxymethyl provided that R2 does not represent either hydrogen or -NHRI in which R1 represents either hydrogen or lower alkyl; or R4 represents lower alkoxymethyl, lower alkylthiomethyl or -CONHR6 in which R6 represents lower alkyl, aryl-lower alkyl, C3-Cscycloalkyl or hydroxy-lower alkyl; pharmaceutically acceptable ester derivatives thereof in which free hydroxy groups are esterified in form of a pharmaceutically acceptable ester; and salts thereof; methods for their preparation; and their use as adenosine receptor agonists are disclosed.
