Darbufelone mesylate is a dual inhibitor of cellular prostaglandin and leukotriene production. Darbufelone potently inhibits PGHS-2 (IC50 = 0.19 uM) but is much less potent with PGHS-1 (IC50= 20 uM). Darbufelone is a dual inhibitor of cellular PGF2R and LTB4 production. Darbufelone is orally active and nonulcerogenic in animal models of inflammation and arthritis. Darbufelone mesylate was in phase III clinical trials by Pfizer and Zhuhai United Laboratories for the treatment of rheumatoid arthritis.

Sample Use Guides

In Vivo Use Guide

Mice were administered Darbufelone by gavage at doses of 20, 40, and 80 mg/kg/day. When mice are treated with Darbufelone at dosage of 80 mg/kg/day, the tumor volumes decrease in a time-dependent manner. In contrast, lower dose of Darbufelone (20 or 40 mg/kg/day) dos not show any significant inhibition of tumor weight.

Route of Administration: Oral

In Vitro Use Guide

In cyclooxygenase assays following a 15-min incubation of enzyme with inhibitor, darbufelone potently inhibits PGHS-2 (IC(50) = 0.19 uM) but is much less potent with PGHS-1 (IC(50) = 20 uM.
