生物活性

Piperine, a natural alkaloid isolated from Piper nigrum L, inhibits P-glycoprotein and CYP3A4 activities with an IC50 value of 61.94±0.054 μg/mL in HeLa cell.

体外研究

Piperine has shown to possess in vitro cytotoxic activity and in silico studies. The IC50 value is found to be 61.94±0.054 μg/mL and in silico studies, it has more number of hydrogen bonds with minimum binding and docking energy and may be considered as inhibitor of EGFR tyrosine kinase. Piperine has been found to have immunomodulatory, anti-oxidant, anti-asthmatic, anti-carcinogenic, anti-inflammatory, anti-ulcer, and anti-amoebic properties. Piperine could enhance the bioavailabilities of other drugs including rosuvastatin, peurarin and docetaxel (DOX) via inhibition of CYP3A and P-glycoprotein activity.

体内研究

At the dose of 3.5 mg/kg, the bioavailability of piperine is calculated to be 25.36%. Its AUC0→t is unproportionally increased with doses, indicating a potential non-linear pharmacokinetics profile of piperine. It is found that the AUC0→t and C0 of docetaxel and t1/2of piperine are significantly increased after their combination use, suggesting potential enhanced bioavailability of not only docetaxel but also piperine, which may lead to the overall enhanced pharmacological effects. The phosphorylation of I-κB, p65, p38, ERK, and JNK is inhibited by piperine in a dose-dependent manner, indicating that piperine may be a potential anti-inflammatory drug both in endometritis and in other S. aureus-induced diseases.
