MedKoo CAT#: 100674

CAS#: 42471-28-3

Description: NIMUSTINE is a antineoplastic agent especially effective against malignant brain tumors. The resistance which brain tumor cells acquire to the initial effectiveness of this drug can be partially overcome by the simultaneous use of membrane-modifying agents such as reserpine, calcium antagonists such as nicardipine or verapamil, or the calmodulin inhibitor, trifluoperazine. The drug has also been used in combination with other antineoplastic agents or with radiotherapy for the treatment of various neoplasms. (Source:

Additional Information

N imustine is a nitrosourea with antineoplastic activity. Nimustine alkylates and crosslinks DNA, thereby causing DNA fragmentation, inhibition of protein synthesis, and cell death. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).
