Abstract
9-(1,3-Dihydroxy-2-propoxymethyl)guanine and 9-(2,3-dihydroxy-1-propoxymethyl)guanine have been found to have potent anti-viral activity against herpes viruses. These compounds, their acyl derivatives, their phosphate derivatives and their pharmaceutically acceptable salts, pharmaceutical formulations containing these compounds, the treatment of DNA viral or herpes viral infections with these compounds, method of preparing these compounds, and novel intermediates useful in their preparation are all disclosed. The compounds may be prepared by reaction of the appropriate acetoxymethyl ether with diacetylguanine, followed by deprotection. The acetoxymethyl ethers may be obtained by reaction of glycerol formal with acetic anhydride in the presence of a catalyst.
