Terms & Properties

Preferred Name: Pentostatin

Definition: A purine nucleotide analogue antibiotic isolated from the bacterium Streptomyces antibioticus. Also known as 2'-deoxycoformycin, pentostatin binds to and inhibits adenine deaminase (ADA), an enzyme essential to purine metabolism; ADA activity is greatest in cells of the lymphoid system with T-cells having higher activity than B-cells and T-cell malignancies higher ADA activity than B-cell malignancies. Pentostatin inhibition of ADA appears to result in elevated intracellular levels of dATP which may block DNA synthesis through the inhibition of ribonucleotide reductase. This agent may also inhibit RNA synthesis and may selectively deplete CD26+ lymphocytes. (NCI04)

NCI-GLOSS Definition: The active ingredient in a drug that is used to treat hairy cell leukemia and is being studied in the treatment of other types of cancer. Pentostatin blocks a protein needed for cell growth and may kill cancer cells. It is made by a bacterium. It is a type of adenosine deaminase inhibitor.
