A tandem enzymatic strategy to enhance the scope of C-alkylation of small molecules via the in situ formation of S-adenosyl methionine (SAM) cofactor analogues is described. A solvent-exposed channel present in the SAM-forming enzyme SalL tolerates 5'-chloro-5'-deoxyadenosine (ClDA) analogues modified at the 2-position of the adenine nucleobase. Coupling SalL-catalyzed cofactor production with C-(m)ethyl

derivatives have been shown to produce a variety of biological effects on the basis of the hypothesis that such agents act directly as inhibitors of transmethylation reactions, as inhibitors of S-adenosylhomocysteine hydrolase, or as inhibitors of polyamine biosynthesis. We report here the ability of selected analogues of SIBA to inhibit the binding of the muscarinic antagonist quinuclidinyl benzilate
(EN) Novel compounds which selectively inhibit adenosine kinase and methods of preparing adenosine kinase inhibitors are provided. Also provided are methods of treating various conditions which may be ameliorated by increased local concentrations of adenosine using adenosine kinase inhibitors.(FR) L'invention se rapporte à de nouveaux composés qui possèdent un pouvoir inhibiteur sélectif sur l'adénosine-kinase, ainsi qu'à des procédés de préparation d'agents inhibiteurs de l'adénosine-kinase. Sont également décrits des procédés qui servent à traiter divers états dont on peut obtenir une amélioration en augmentant les concentrations locales d'adénosine et qui utilisent à cet effet des agents inhibiteurs de l'adénosine-kinase.
