개요
Colchicine is a pale-yellow powder that is obtained from various species of Colchicum, primarily Colchicum autumnale L. Its total chemical synthesis has been achieved, but the primary source of colchicine currently remains alcohol extraction of the alkaloid from the corm and seed of C. autumnale L. It darkens on exposure to light and possesses
역사
Meadow saffron (Colchicum) is recorded to treat rheumatic swelling on ancient Egyptian medical papyrus in 1500 B.C.. According to De Materia Medica written by Pedanius Dioscorides in the first century, extract of Meadow saffron is used in treating gout. London Pharmacopoeia in 1618 recorded that colchicine is also applied to treat gout.In 1820, the ingredient was first isolated by the French chemist P.S. Pelletier and J.B. Caventou. In 1833, it was purified and named by Geiger. Michael Dewar guessed that there are two seven-membered rings in colchicine in 1945. Murray Vernon King et al. determined the structure of colchicine by X-ray diffraction in 1952. In 1959, Albert Eschenmoser integrated the product successfullyColchicine tablet and raw material are approved mostly in domestic in 2010. The tablet produced by Taiwan manufacturers is approved for being listed in mainland of China in 2012. The raw material made by Indian obtained the approval in 2013. There are three kinds of colchicine approved by FDA: with the combination of probenecid, it is prior to be approved. The others are tablet (2009) and capsule (2014).
용도
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.
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.
