Tetrahydrocoptisine ((RS)-Stylopine) (Synonyms: NSC 110382, NSC 404529, (R,S±)-Stylopine)

Tetrahydrocoptisine is an alkaloid compound originally isolated from Corydalis tubers that exhibits anti-inflammatory and anti-parasitic activities.IC50 value:Target:in vitro: THC significantly inhibited LPS-induced TNF-α, interleukin-6(IL-6) and nitric oxide (NO) production. THC inhibited the production of TNF-α and IL-6 by down-regulating LPS-induced IL-6 and TNF-α mRNA expression [1].in vivo: Pretreatment with THC (i.p.) inhibited the paw and ear edema in the carrageenan-induced paw edema assay and xylene-induced ear edema assay, respectively. In the lipopolysaccharide (LPS)-induced systemic inflammation model, THC significantly inhibited serum tumor necrosis factor-alpha (TNF-α) release in mice [1]. Pretreatment of THC at doses of 10 and 20mg/kg bodyweight significantly attenuated the gastric lesions as compared to the ethanol group [2].
