Uses

Colchicine(64-86-8) is used as an antimitotic agent that disrupts microtubles by binding to tubulin and preventing its polymerization. Stimulates the intrinsic GTPase activity of tubulin. Induces apoptosis in several normal and tumor cell lines and activates the JNK/SAPK signal.

Safety Profile

A human poison by ingestion and intravenous routes. Poison experimentally by most routes. Human systemic effects: aplastic anemia, blood pressure depression, body temperature decrease, changes in kidney tubules, dyspnea, flaccid paralysis without anesthesia, gastrointestinal effects, kidney damage and hemorrhaging, muscle contraction or spasticity, muscle weakness, nausea or vomiting, respiratory stimulation, and somnolence. An experimental teratogen. Experimental reproductive effects. A severe eye irritant. Human mutation data reported. Inhibits the formation of microtubules and thus impairs cell division. When heated to decomposition it emits toxic fumes of NO_x.
Hazard Codes: Very T+, Toxic T
Risk Statements: 26/28
R26/28:Very toxic by inhalation and if swallowed.
Safety Statements: 13-45
S13:Keep away from food, drink and animal foodstuffs.
S45:In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
