Chemical compound

Nitrosourea is both the name of a molecule, and a class of compounds that include a nitroso (R-NO) group and a urea.

Examples

Examples include:

Arabinopyranosyl-N-methyl-N-nitrosourea (Aranose)
Carmustine (BCNU, BiCNU)
Chlorozotocin
Ethylnitrosourea (ENU)
Fotemustine
Lomustine (CCNU)
Nimustine
N-Nitroso-N-methylurea (NMU)
Ranimustine (MCNU)
Semustine
Streptozocin (Streptozotocin)

Nitrosourea compounds are DNA alkylating agents and are often used in chemotherapy.^[1] They are lipophilic and thus can cross the blood–brain barrier, making them useful in the treatment of brain tumors such as glioblastoma multiforme.^[2]

Side effects

Some nitrosoureas (e.g. lomustine) have been associated with the development of interstitial lung disease.^[3]
