General information

Class/mechanism: Purine analog, antimetabolite. Nelarabine is metabolized to the cytotoxic deoxyguanosine analogue, 9-β-Darabinofuranosylguanine (ara-G), which is eventually converted to ara-GTP. ara-GTP is incorporated into DNA and leads to inhibition of DNA synthesis and cell death.[1][2]
Route: IV
Extravasation: neutral
