Sample Use Guides

In Vivo Use Guide

In anti-canrogenesis experiments rats were fed by experimental diets, made by mixing columbin at doses of 4, 20, and 100 ppm with a powdered CE-2 basal diet. Anti-inflammatory activity was evaluated in carrageenan-induced mice paw oedema test. Columbin was intra-peritoneally administered to mice at the dose of 30, 100, 300 and 700 mg/kg.

Route of Administration: Oral

In Vitro Use Guide

COX-2 activity was tested using COX-inhibitor screening kit (Cayman Chemical, USA). This assay measures the production of PGF2-alpha generated by SnCl2, in the presence of PGH2. Columbin inhibits COX-2 with IC50 of 53 uM.
