Description
Curator's Comment: Description was created based on several sources, including http://www.rxlist.com/hexalen-drug/warnings-precautions.htm http://www.survivorlibrary.com/library/anticancer-therapeutics.pdf#page=146 https://books.google.ru/books?hl=ru&lr=&id=VEibBwAAQBAJ&oi=fnd&pg=PP1&dq=Hexamethylmelamine+formaldehide&ots=-eXXGg_pDu&sig=H4nRJZrJvcJ4rK6AIQe68qCP_KI&redir_esc=y#v=onepage&q&f=false https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=8456a8db-a7f6-4bc0-86be-e9c8c374140b

Altretamine is structurally similar to the alkylating agent triethylenemelamine (tretamine). Although Altretamine structurally resembles an alkylating agent, it has not been found to have alkylating activity in vitro. The precise mechanism of Altretamine cytotoxicity is unknown, although several proposals have been made. Altretamine requires N-demethylation in the liver to produce reactive intermediates (formaldehyde and/or iminium species) which covalently bind to DNA, resulting in DNA damage, or act as alkylating agents. Altretamine is used as a palliative treatment for persistent or recurrent ovarian cancer following treatment failure with a cisplatin- or alkylating agent-based combination. Side effects of Altretamine include nausea and vomiting, neurotoxicity (mood disorders, disorders of consciousness, ataxia, dizziness, vertigo), mild to moderate dose-related myelosuppression. Altretamine has been shown to be embryotoxic and teratogenic in rats and rabbits and may cause fetal damage when administered to a pregnant woman. Under the trade name Hexalen, Altretamine, is an antineoplastic agent. It is indicated for use as a single agent in the palliative treatment of patients with persistent or recurrent ovarian cancer following first-line therapy with a cisplatin and/or alkylating agent-based combination.

CNS Activity

Curator's Comment: Altretamine itself has poor CNS penetration. Its demethylated metabolites occur in high concentrations in cerebrospinal fluid and may be concentrated in the brain. Altretamine side effects include central neurotoxicity (rare) and peripheral neurotoxicity.

Originator

Curator's Comment: The synthesis of hexamethylmelamine (Altretamine) was first reported in 1951 (Kaiser et al., 1951).

Sample Use Guides

HEXALEN® (altretamine) capsules are administered orally. Doses are calculated on the basis of body surface area. HEXALEN® (altretamine) capsules may be administered either for 14 or 21 consecutive days in a 28-day cycle at a dose of 260 mg/m²/day. The total daily dose should be given as 4 divided oral doses after meals and at bedtime.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: Hexamethylmelamine inhibited colony formation when incubated with A204 cells for 1 hour (short-term exposure) in the presence of the hepatic metabolizing system (S-9).
Long-term (10-day) exposure of Hexamethylmelamine (Altretamine) inhibited colony formation by human rhabdomyosarcoma cell line A204 by 70% at a concentration of 150 ug/ml.
