This paper reports the effect of two different doses (0.1 and 1 mg/g) of misonidazole on the radiosensitivity of human Na 11 melanoma transplanted into athymic nude mice. The mice were irradiated with 50 MeV neutrons. The end point was the in vitro colony-forming assay. Repair of potentially lethal damage following neutron irradiation was comparable to that observed after gamma irradiation. This repair was no longer detectable when 1 mg/g of misonidazole was used. When the 1 mg/g dose was used, the observed enhancement ratios after neutron irradiation were 1.52 for immediate plating and 1.87 for delayed plating. No toxic effect of the drug itself could be detected.

D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008920 Misonidazole A nitroimidazole that sensitizes normally radio-resistant hypoxic cells to radiation. It may also be directly cytotoxic to hypoxic cells and has been proposed as an antineoplastic.
