In vitro

Gentiopicroside (GE) is a non-competitive inhibitor of CYP2A6 at lower concentrations and a competitive inhibitor at higher concentrations. Gentiopicroside does not produce inhibition of CYP2C9, CYP2D6, CYP1A2 or CYP3A4 activities. However, a significant increase of CYP1A2 and CYP3A4 activity is observed at high concentrations. In cultured human hepatocytes no significant induction of CYP1A2, CYP3A4 or CYP2B6 is observed[1].

In vivo Gentiopicroside (GE) has a low bioavailability (%F) after oral administration, which may be attributed to the first-pass metabolism in the gut wall or liver, metabolism or decomposition in the intestine by bacterial microflora, and/or poor absorption from the gastrointestinal tract. The Phase I clinical study shows that after intravenous infusion of 80, 240, and 400 mg GE, the mean Cmax are 3.501±0.566 μg/ml, 9.865±1.237 μg/ml, and 16.95±2.571 μg/ml, respectively[1]. GPS can act as hepatoprotective, cholagogic, anti-inflammatory, and antibacterial agents[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
