描述 | Piperine is a natural alkaloid isolated from pepper and inhibits the activity of P-glycoprotein and CYP3A4 with IC50[3]. In vivo, at the dose of 3.5 mg/kg, the bioavailability of Piperine was calculated to be 25.36% and its AUC0→t was unproportionally increased with doses[4]. Moreover, piperine effectively reduced the aureus-induced overexpression of TNF-α, IL-1β, and IL-6 but increased the expression of IL-10. The phosphorylation of I-κB, p65, p38, ERK, and JNK was inhibited by piperine in a dose-dependent manner[5]. Piperine has been found to have immunomodulatory, anti-oxidant, anti-asthmatic, anti-carcinogenic, anti-inflammatory, anti-ulcer, and anti-amoebic properties[6]. |
