9-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 pharmaceutically acceptable salts, pharmaceutical formulation 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.

Novel 2-amino substituted adenine compounds and their use as antiviral compounds are disclosed. In particular the compound 2-amino-9-(2-hydroxyethoxymethyl) adenine is particularly advantageous as an antiviral in that it has high oral absorption and that upon metabolism in mammals, it has the property of being converted to 9-(2-hydroxyethoxymethyl) guanine which is also a highly active antiviral.
11-ether derivatives of erythromycin, and corresponding 9-(optionally substituted)-amino, 9-imino, and 9-(optionally substituted)-oxime derivatives are novel antibacterially active compounds, and can be prepared by alkylation of the 11-hydroxy group under mild conditions.
