Pentostatin (or deoxycoformycin, trade name Nipent, manufactured by SuperGen) is an anticancer chemotherapeutic drug.[1]
Mechanism
It 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.[2]
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.
Uses
Pentostatin is used to treat hairy cell leukemia.[3] 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.[4]
Pentostatin is also used in chronic lymphocytic leukemia (CLL) patients who have relapsed.
