콜키신 C화학적 특성, 용도, 생산

화학적 성질

Yellow Solid

화학적 성질

Colchicine is a pale yellow powder. It has little or no odor. It darkens on contact with light.


Binds specifically with tubulin thus interfering with microtubule organization.


antimitotic, antigout agent


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 t umor cell lines and activates the JNK/SAPK signaling pathway.


anti-inflammatory agent, mitosis inhibitor


For treatment and relief of pain in attacks of acute gouty arthritis.


In research in plant genetics (for doubling chromosomes).


Colchicine is present in the poisonous autumncrocus (meadow saffron). It is the major alkaloid of Colchicum autumnale L. and Liliaceae. It was used in poison potions in theancient kingdom of Colchis (Greece). It isused therapeutically as an antineoplast, for thesuppression of gout, and in the treatment ofMediterranean fever. It is used in plant studiesfor doubling chromosome groups.


Colchicine, an alkaloid obtained from the autumn crocus, has long been used and is relatively selective for the treatment of acute gouty arthritis. Unlike many of the newer agents for use in gout, colchicine has minimal effects on uric acid synthesis and excretion; it decreases inflammation associated with this disorder. It is thought that colchicine somehow prevents the release of the chemotactic factors and/or inflammatory cytokines from the neutrophils, and this in turn decreases the attraction of more neutrophils into the affected area .The ability of colchicine to bind to leukocyte microtubules in a reversible covalent complex and cause their depolymerization also may be a factor in decreasing the attraction of the motile leukocytes into the inflamed area.


An alkaloid plant hormone.


colchicine: An alkaloid derivedfrom the autumn crocus, Colchicumautumnale. It inhibits cell division.Colchicine is used in genetics, cytology,and plant breeding research andalso in cancer therapy to inhibit celldivision.

일반 설명

Odorless or nearly odorless pale yellow needles or powder that darkens on exposure to light. Used to treat gouty arthritis, pseudogout, sarcoidal arthritis and calcific tendinitis.

일반 설명

Colchicine is an alkaloid isolated from the dried corns andseeds of Colchicum autumnale L., commonly known as autumncrocus or meadow saffron.It is specifically indicated for acute treatment of goutyarthritis because of its ability to block the production and releaseof the CCF that mediates the inflammatory responsebecause of urate crystals, a mechanism different fromcolchicine’s antimitotic action, which is being investigatedfor its anticancer properties. It is often quite effective inaborting an acute gouty attack if given within the first 10 to12 hours after the onset of arthritis.

공기와 물의 반응

Slowly hydrolyzed in acidic solution, but unbuffered solutions are stable at 68°F for at least six months. Isomerizes on exposure to ultraviolet radiation.

반응 프로필

Colchicine darkens on exposure to light. Incompatible with strong oxidizing agents. Also incompatible with mineral acids .


As little as 20 mg may be fatal if ingested.


Colchicine is a highly toxic alkaloid. Thetarget organs are the lungs, kidney, gastrointestinal tract, and blood. The toxiceffects include drowsiness, nausea, hypermotility, diarrhea, lowering of body temperature, lowering of blood pressure, tremors,convulsions, and respiratory distress. Chronicingestion may cause aplastic anemia andhemorrhage.
LD50 value, oral (mice): 5.9 mg/kg
Colchicine solution at 10,000 ppm concentration caused severe irritation whenapplied repeatedly to rabbits’ eyes. Colchicine produced teratogenic effects in testanimals. It caused fetal death, cytologicalchanges, and developmental abnormalitiesin hamsters, rabbits, domestic animals,and mice. It tested positive to in vitromammalian nonhuman micronucleus andD. melanogaster — nondisjunction tests formutagenicity (U.S. EPA 1986; NIOSH1986).


Colchicine is classified as super toxic. Probable oral lethal dose in humans is less than 5 mg/kg, i.e. less than 7 drops for a 70 kg (150 lb.) person. Death results from respiratory arrest. The fatal dose varies considerably; as little as 7 mg of Colchicine has proved fatal.



생물학적 활성

Plant-derived alkaloid that binds to tubulin and depolymerizes microtubules.

Mechanism of action

Colchicine is rapidly absorbed after oral administration and tends to concentrate in the spleen, kidney, liver, and gastrointestinal tract. Leukocytes also avidly accumulate and store colchicine even after a single intravenous injection. Since colchicine can accumulate in cells against a concentration gradient, it is postulated that an active transport process may be involved in its cellular uptake. The drug is metabolized, primarily in the liver, by deacetylation. Fecal excretion plays a major role in colchicine elimination, since it and its metabolites are readily secreted into the bile. Only about 15 to 30% of the drug is eliminated in the urine except in patients with liver disease; urinary excretion is more important in these individuals.


The drug can be given intravenously as well as orally, but care must be exercised, since extravasated drug may result in local sloughing of skin and subcutaneous tissues. Relief of pain and inflammation usually occurs within 48 hours. Small doses of colchicine can be used during asymptomatic periods to minimize the reappearance or severity of acute attacks. It should be used with caution in patients with preexisting compromised heart, kidney, gastrointestinal tract, and liver disease. Diarrhea, nausea, vomiting, and abdominal pain are the major limiting side effects that ultimately determine the tolerated dosage. These symptoms occur in approximately 80% of patients who take colchicine, especially in those taking high dosages. The hepatobiliary recycling of colchicine and its antimitotic effect on cells that are rapidly turning over, such as those of the intestinal epithelium, account for its gastrointestinal toxicity. Gastrointestinal symptoms generally intervene before the appearance of more serious toxicity and thereby provide a margin of safety in drug administration. Ingestion of large doses of colchicine may be followed by a burning sensation in the throat, bloody diarrhea, shock, hematuria, oliguria, and central nervous system (CNS) depression.

Anticancer Research

It is a natural toxic secondary metabolite, extracted from Colchicum genus plants. Itprevents gastric cancer by upregulating the dual specificity phosphatase 1 (DUSP1)gene. It is also reported to upregulate transforming growth factor beta 2 (TGF-β2)and A-kinase anchoring protein 12 (AKAP12) in hepatocellular carcinoma (Singhet al. 2016b).

Clinical Use

The major use of colchicine is as an antiinflammatory agent in the treatment of acute gouty arthritis; it is not effective in reducing inflammation in other disorders. It also can be used to prevent attacks. Since colchicine is so rapidly effective in relieving the acute symptoms of gout (substantial improvement is achieved within hours), it has been used as a diagnostic aid in this disorder. Therapy with colchicine is usually begun at the first sign of an attack and is continued until symptoms subside, adverse gastrointestinal reactions appear, or a maximum dose of 6 to 7 mg has been reached.

Safety Profile

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 NOx.

잠재적 노출

Colchicine is a drug used to treat gouty arthritis, pseudogout, sarcoidal arthritis; and calcific tendonitis.

Veterinary Drugs and Treatments

In veterinary medicine, colchicine has been proposed as a treatment in small animals for amyloidosis. For colchicine to be effective, however, it must be given early in the course of the disease and it will be ineffective once renal failure has occurred. At the time of writing, no conclusive evidence exists for its efficacy for this indication in dogs.
Colchicine has also been proposed for treating chronic hepatic fibrosis presumably by decreasing the formation and increasing the breakdown of collagen.
