The invention relates to a method for detecting adenosine with the inactive S-adenosyl homocysteine hydrolase's enzyme which selectively and only binds adenosine with high affinity. The inventive method enables adenosine to be determined in small sample volumes without the need for additional purification of said sample.

The present invention describes 1,6-naphthyridine derivatives of the general formula: ##STR1## wherein R.sup.1 is an unsubstituted or substituted aromtic or heteroaromatic ring, R.sup.2 is a straight-chained or branched alkyl radical containing up to four carbon atoms or a benzyl radical, R.sup.3 is a hydrogen atom, a straight-chained or branched alkyl radical or an alkoxycarbonyl radical containing up to four carbon atoms, R.sup.4 is a straight-chained or branched alkyl radical containing up to four carbons and R.sup.5 is a carbonyl group or a straight-chained, branched or cyclic alkoxycarbonyl radical which contains up to 17 carbon atoms and optionally also contains an oxygen, sulphur or nitrogen atom; as well as the pharamacologically acceptable salts thereof, which are useful for treating diseases of the blood vessels.
