Colchicum speciosum
Crocus d'automne à fleurs grandes de Turquie et du Caucase, source de colchicine similaire au crocus d'automne commun.
Colchicum speciosum, a large-flowered autumn crocus native to Turkey and the Caucasus, is a primary botanical source of the alkaloid colchicine, which is used pharmaceutically for acute gout flares and in anticancer research. The plant also contains demecolcine and colchicoside, contributing to its traditional use in tiny doses for joint pain in Persian and Turkish medicine. However, all parts are highly toxic, and crude plant material must not be used without pharmaceutical processing.
Colchicine binds to tubulin, preventing microtubule polymerization and thereby inhibiting mitotic spindle formation, which disrupts cell division and reduces inflammatory cell migration. It also inhibits neutrophil chemotaxis and superoxide production by blocking microtubule-dependent processes, and modulates the NLRP3 inflammasome, decreasing IL-1β release. Demecolcine similarly binds tubulin but with different affinity, while colchicoside exhibits anti-inflammatory activity via COX-2 inhibition and antioxidant effects.
