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

Theobromine (3,7-Dimethylxanthine) is a xanthine alkaloid that is used as a bronchodilator and as a vasodilator. It has a weaker diuretic activity than theophylline and is also a less powerful stimulant of smooth muscle. Unlike caffeine, this compound has practically no stimulant effect on the central nervous system. In contrast, it may improve mood and cognition via peripheral physiological changes. It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension.
