Inventor(s): von Borstel; Reid W. (Potomac, MD), Bamat; Michael K. (Potomac, MD), Hiltbrand; Bradley M. (Columbia, MD)
Assignee: Pro-Neuron, Inc. (Rockville, MD)
Filing Date:Jun 05, 1995
Application Number:08/464,939
Claims:1. A method for treating cancer consisting essentially of administering to an animal a therapeutically effective amount of a therapeutic cytokine or inflammatory stimulus and a therapeutically effective amount of a pyrimidine nucleotide precursor prior to, during, or after administration of said cytokine or said stimulus, wherein said pyrimidine nucleotide precursor is a pyrimidine nucleoside or prodrug thereof.

2. A method as in claim 1 wherein said pyrimidine nucleotide precursor is uridine, cytidine, orotic acid, or an acyl derivative of uridine, cytidine, or orotic acid, or a pharmaceutically acceptable salt thereof.

3. A method as in claim 2 wherein said acyl derivative of uridine is triacetyluridine.

4. A method as in claim 1 wherein said cytokine or said stimulus is selected from the group consisting of interleukin 1, interleukin-2, interleukin 6, tumor necrosis factor, endotoxin, fungal polysaccharides, and double-stranded RNA.

5. A method as in claim 1 further comprising the step of administering an inhibitor of uridine phosphorylase.

6. A method for treating cancer comprising administering to an animal a therapeutically effective amount of a therapeutic cytokine or inflammatory stimulus and a therapeutically effective amount of an inhibitor of uridine phosphorylase prior to, during, or after administering said cytokine or said stimulus.
