Abstract
Abstract New purine nucleoside 3'',5''-cyclicphosphate compounds are disclosed wherein the 5'' carbon atom of the furanose sugar moiety bears one or two alkyl groups. Also disclosed are methods for the preparation of these compounds, which are useful as intracellular mediators of hormone effects. 9-(6-Deoxy- Beta -D-allofuranosyl)adenine 3'',5''-cyclicphosphate, 9-(6-deoxy- Alpha -Ltalofuranosyl)-adenine 3'',5''-cyclicphosphate, and 5'',5''-di-Cmethyl-adenosine 3'',5''-cyclicphosphate, are illustrated as representative of the compound class.
