Piperine (1-Piperoylpiperidine; Bioperine; 1-Piperoyl piperidine), a natural alkaloid found in Piper nigrum L, is an alkaloid accounting for the pungency of black pepper and long pepper, which has been used in some forms of traditional medicine and as an insecticide. It inhibits P-glycoprotein and CYP3A4 activities with an IC50 value of 61.94±0.054 μg/mL in HeLa cell.
| ln Vitro |
It has been demonstrated in vitro and in silico investigations that piperine possesses cytotoxic action. The value of IC50 is 61.94 μg/mL. Based on computational analyses, it possesses the greatest number of hydrogen bonds, the lowest binding and docking energy, and is potentially an inhibitor of EGFR tyrosine kinase [1]. It has been discovered that piperine possesses anti-inflammatory, anti-cancer, antioxidant, anti-asthmatic, anti-ulcer, and anti-amoebic qualities [2]. By reducing CYP3A and P-glycoprotein activity, piperine can enhance the bioavailability of various medications, including paclitaxel, docetaxel, and rosuvastatin (DOX) [3].

| ln Vivo |
Piperine has a 25.36% bioavailability at a dose of 3.5 mg/kg. Piperine has a disproportionate dose-dependent increase in its AUC0→t, suggesting the possibility of nonlinear pharmacokinetic properties. After combination use, it was discovered that the t1/2 of piperine and the AUC0→t and C0 of docetaxel were dramatically elevated. The data indicates that concomitant administration enhances both the bioavailability of docetaxel and piperine, potentially contributing to a greater overall improvement in pharmacological effects [3]. Piperine exhibits a dose-dependent inhibition of the phosphorylation of I-κB, p65, p38, ERK, and JNK, indicating its potential as an anti-inflammatory medication for endometritis and other Staphylococcus aureus-related illnesses [4].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
