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.

Mechanism of Action

In vitro
Tea polyphenols are known as catechins. The catechins are subject to extensive biotransformation including methylation, glucuronidation, sulfation and ring-fission metabolism. (−)-epigallocatechin gallate (EGCG) is the major catechin in tea. Among tea catechins, EGCG is most effective in reacting with most reactive oxygen species.
In vivo
The potential health effects of Tea polyphenols (catechins) depend on the amount consumed and on their bioavailability. Following oral administration to rats, tea catechins are absorbed intestinally. They are rapidly and extensively metabolized in rats.
