9 (β D Xylofuranosyl)guanine (xylo G) was converted chemically to the 9 (β D xylofuranosyl)guanine 5' monophosphate (xylo GMP) and 9 (β D xylofuranosyl)guanine cyclic 3',5' monophosphate (c xylo GMP). These compounds were tested against a variety of DNA viruses in tissue culture in parallel with 9 D arabinofuranosyl)adenine Darabinofuranosyl)adenine (ara A). This evaluation revealed that xylo G, xylo GMP, and c xylo GMP were all moderately active but less effective than ara A. When the four compounds were administered intracerebrally as a treatment for herpes virus, type 1 induced encephalitis in mice, c xylo GMP exhibited superior activity to that shown by the other three. When administered intraperitoneally, c xylo GMP was found to have a therapeutic index of about 4, which is less than that for ara A (30) in the same system.
