NCIt definition : The hydrochloride salt form of methoxyamine, an alkoxyamine with potential chemotherapeutic
adjuvant activity. Methoxyamine covalently binds to apurinic/apyrimidinic DNA damage
sites and thereby inhibits base excision repair (BER) process, which may prevent repair
of DNA strand breaks and result in an induction of apoptosis. This agent may potentiate
the anti-tumor activity of alkylating agents.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of cancer. It blocks the ability
of a cell to repair damage to its DNA and may kill cancer cells. It may also help
some anticancer drugs work better. It is a type of antineoplastic agent.;
