Background

Tetrahydrocoptisine is an alkaloid that has been found in C. impatiens and has anti-inflammatory and antioxidant activities.^1,2 It inhibits LPS-induced NF-κB activation and production of nitric oxide (NO), TNF-α, and IL-6 in isolated mouse peritoneal macrophages when used at concentrations ranging from 0.001 to 1 ?g/ml.¹ Tetrahydrocoptisine (10 and 30 mg/kg) inhibits xylene-induced ear edema in mice, and it decreases serum levels of TNF-α in a mouse model of LPS-induced septic shock. It reduces the severity of ethanol-induced gastric ulcers in mice when administered at doses of 10 or 20 mg/kg.²
