NCIt definition : A chloroethylating nitrosourea with antineoplastic activity. Fotemustine alkylates
guanine by forming chloroethyl adducts at the 6 position of guanine, resulting in
N1-guanine and N3-cytosine cross linkages, inhibition of DNA synthesis, cell cycle
arrest, and finally apoptosis. This agent is lipophilic and crosses the blood-brain
barrier.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of brain tumors and metastatic
