NCI: The hydrochloride salt of mechlorethamine, a nitrogen mustard and an analogue of sulfur mustard, with antineoplastic and immunosuppressive activities. Mechlorethamine is metabolized to an unstable, highly reactive ethyleniminium intermediate that alkylates DNA, particularly the 7 nitrogen of guanine residues, resulting in DNA base pair mismatching, DNA interstrand crosslinking, the inhibition of DNA repair and synthesis, cell-cycle arrest, and apoptosis. This agent also exhibits lympholytic properties.,PDQ: The hydrochloride salt of a synthetic agent related to sulphur mustard with antineoplastic and immunosuppressive properties. Nitrogen mustard (a member of a family of chemotherapy agents including cyclophosphamide and chlorambucil) is an irritant and carcinogenic agent metabolized to a highly reactive ethylene immonium derivative; the ethylene immonium derivative alkylates DNA and inhibits DNA replication. This agent also exhibits lympholytic properties. Check for "http://www.cancer.gov/Search/Clinica
