Also known as 9-beta-D-ribofuranosyl-3,9-dihydro-1H-purine-2,6-dione, xanthine 9-beta-D-ribofuranoside, 9-beta-D-Ribofuranosylxanthine, Xanthine riboside, 9-[(2R,3R,4R,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl]-3H-purine-2,6-dione, 9-[(2R,3R,4R,5R)-3,4-dihydroxy-5-methylol-tetrahydrofuran-2-yl]-3H-purine-2,6-quinone, 9-[(2R,3R,4R,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-3H-purine-2,6-dione, 3,9-Dihydro-9-delta-ribofuranosyl-1H-purine-2,6-dione

Xanthosine is a nucleoside derived from xanthine and ribose. It is the biosynthetic precursor to 7-methylxanthosine by the action of 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (active alkaloid in chocolate), which in turn is the precursor to caffeine, the alkaloid in coffee and tea.
