A novel nucleoside, in the amount of 400 micrograms, was isolated from a 24-h collection of urine of a chronic myelogenous leukemia patient. On the basis of ultraviolet, nuclear magnetic resonance, and mass spectrometry and chromatography, its structure was established to be 7-beta-D-ribofuranosylhypoxanthine. The ultraviolet and mass spectral data and the thin layer chromatographic mobilities of the natural material were identical to those of a synthetic sample. High performance liquid chromatographic retention times and the coinjection high performance liquid chromatography of the natural material with the synthetic samples of the alpha and beta-anomers of 7-ribofuranosylhypoxanthines further confirmed the identity of the isolated material as 7-beta-D-ribofuranosylhypoxanthine.
