Columbin Chemical Properties,Usage,Production

Chemical Properties

White needle-shaped crystals, easily soluble in methanol and ethyl acetate, almost insoluble in water, derived from Jin Guolan.

Uses

Columbin is a furanolactone diterpene isolated from the roots of Jateorhiza and Tinospora species and is used in Asian and African folk medicine for analgesic and antipyretic properties.

Definition

ChEBI: Columbin is an organic heterotricyclic compound and an organooxygen compound.

in vivo

Columbin inhibits oedema formation in mice paw. At doses of 300 mg/kg and 700 mg/kg, columbin inhibits inflammation from 0 to 5 h and the results are comparable to that of aspirin as a standard anti-inflammatory drug. The inhibitory effect of columbin on carrageenan induced paw oedema in mice may be due to the suppression of the release of mediators responsible for inflammation including prostaglandin^[1]. Columbin is poorly bioavailable (2.8% p.o. and 14% i.p.) in rats, but its transport is rapid across the Caco-2 cell monolayers, suggesting that extensive first-pass metabolism in the liver is the likely reason for its poor bioavailability^[2].

IC 50

Trypanosoma; COX-2: 53.1 μM (EC₅₀); COX-1: 327 μM (EC₅₀)
