  • Patent number: 4017606
    Abstract: Novel hydrogenated pyrimidine nucleosides and nucleotides are produced by catalytic hydrogenation, particularly in the presence of a rhodium catalyst. The novel compounds are specifically used to inhibit deaminating enzymes, which would inactivate cytosine arabinoside by conversion to uridine arabinoside. Cytosine arabinoside is used for its anti-viral, particularly anti-herpes and anticytotoxic activity in mammals and birds, as well as to destroy phages which interfere with the production of antibiotics. Novel formulations containing cytosine arabinoside and the hydrogenated pyrimidine nucleosides are advantageous to provide prolonged cytosine arabinoside effects.
