Abstract
Abstract A method of increasing the rate of repletion of purine nucleotide pools in tissue deficient in the nucleotides, which comprises administering to a human or animal a therapeutically effect amount of 5-amino-4-imidazolecarboxamide riboside, 5-amino-4-imidazolecarboxamide, or a pharmaceutically acceptable salt thereof sufficient to increase the rate of the repletion is disclosed along with pharmaceutical compositions useful for carrying out the method of the invention.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
49 words
A method of increasing the rate of repletion of adenosine triphosphate and guanosine triphosphate nucleotides in a tissue deficient in said nucleotides, which comprises: administering to said tissue a therapeutically effect amount of 5-amino-4-imidazolecarboxamide riboside or a pharmaceutically acceptable salt thereof sufficient to increase the rate of said repletion.
Claim 2
Independent Claim
49 words
A method of increasing the rate of repletion of adenosine triphosphate and guanosine triphosphate nucleotides in a tissue deficient in said nucleotides, which comprises: administering to said tissue a therapeutically effect amount of 5-amino-4-imidazolecarboxamide riboside or a pharmaceutically acceptable salt thereof sufficient to increase the rate of said repletion.
