Chlorozotocin

Chemical properties

Chlorozotocin is a nitrosourea compound that exists as ivory-coloredcrystals at room temperature. It is soluble in water and is stable in solution at room temperature for up to 3 hours and under refrigeration for 24 hours. The powder form of chlorozotocin is stable under refrigeration for two years. The spontaneous, nonenzymatic degradation of chlorozotocin results in formation of DNA-alkylating and protein-carbamoylating moieties (Chabner et al. 2001).

The Uses of Chlorozotocin

Chlorozotocin is a cytostatic agent that has been used to treat melanoma and multiple myeloma and cancer of the stomach, large intestine, pancreas, and lung (IARC 1990).

Definition

ChEBI: Chlorozotocin is an amino sugar.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by intravenous route: anorexia, leukopenia, nausea or vomiting, thrombocytopenia. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cland NOx. See also NITROSAMINES.

Carcinogenicity

Chlorozotocin is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals and because it is a member of a well-defined, structurally related class of substances listed in the Report on Carcinogensas either known to be a human carcinogen or reasonably anticipated to be a human carcinogen.
