Abstract
9-(2-Hydroxyethoxymethyl) (and related) derivatives of certain 6-, and 2,6-substituted purines have been discovered to have potent anti-viral activities. Novel compounds and their pharamceutically acceptable salts, pharmaceutical formulations containing the compounds of this invention, and the treatment of viral infections with these formulations are all disclosed. 9-(2-Hydroxyethoxymethyl)guanine and 2-amino-9-(2-hydroxyethoxymethyl) adenine are examples of especially active compounds of this invention. Also preferred because of its high oral absorption is the phosphate and especially the monophosphate of 9-(2-hydroxyethoxymethyl)guanine as well as pharmaceutically acceptable salts thereof.
