title: Modification of the 5' position of purine nucleosides. 1. Synthesis and biological properties of alkyladenosine-5'-carboxylates.
abstract: A series of esters of adenosine-5'-carboxylic acid has been prepared. Most of the compounds were nontoxic, causing prolonged increases in coronary sinus PO2 when administered to anesthetized dogs; the ethyl ester was most active. Nitrosation and oxidation of the ethyl ester 12 gave respectively inactive inosine ethyl ester 30 and the fairly active N1-oxide ethyl ester 29.
