Background:

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.


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[1]. Piperine has been found to have immunomodulatory, anti-oxidant, anti-asthmatic, anti-carcinogenic, anti-inflammatory, anti-ulcer, and anti-amoebic properties[2]. Piperine could enhance the bioavailabilities of other drugs including rosuvastatin, peurarin and docetaxel (DOX) via inhibition of CYP3A and P-glycoprotein activity[3].


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[3]. 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[4].
