CAS#: 53910-25-1

Description: Pentostatin is classified as a purine analog, which is a type of antimetabolite. It mimics the nucleoside adenosine and thus inhibits the enzyme adenosine deaminase, interfering with the cell's ability to process DNA. Cancer cells generally divide more often than healthy cells; DNA is highly involved in cell division (mitosis) and drugs which target DNA-related processes are therefore more toxic to cancer cells than healthy cells. Pentostatin is used to treat hairy cell leukemia. It is given by intravenous infusion once every two weeks for three to six months. Additionally, pentostatin has been used to treat steroid-refractory acute and chronic graft-versus-host disease. Pentostatin is also used in chronic lymphocytic leukemia (CLL) patients who have relapsed. (Source: http://en.wikipedia.org/wiki/Pentostatin)

Bulk inquiry Welcome, Customer: Please do not inquire quote if your intended use is for a patient since our products are for research use and for chemical synthesis use, not for human use . For in-stock products, we listed price in the web page. You may inquire prices for which sizes were not listed. If no price is listed, this means the product is not in stock at the moment, which may be available via custom synthesis. For cost-effective reason, minimum order of 1g is requested (typically very expensive). The lead time is usually 2-4 months. Quote of less than 1g will not be provided. MedKoo may not offer quote for below reasons: (1) current available synthetic method appears to be extremely expensive which is obviously not affordable to most customers; (2) Key raw material to make the product is temporally not available; (3) DEA controlled substances; (4) the product is under patent protection in customer’s country.

More Info: Pentostatin is 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. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus). Pentostatin is used to treat hairy cell leukemia. It is given by intravenous infusion once every two weeks for three to six months. Additionally, pentostatin has been used to treat steroid-refractory acute and chronic graft-versus-host disease. Pentostatin is also used in CLL patients who have relapsed.
