Entacapone, a nitrocatechol compound, is a selective and reversible inhibitor of catechol-O-methyltransferase (COMT), a Mg2+-dependent enzyme involved in the metabolism of catecholamines and catechol compounds, with the half maximal inhibition concentration IC50 and inhibition constant Ki values of 20.1 nM and 10.7 nM respectively [1 & 2].
The nitro group at the position ortho to the hydroxyl group in the chemical structure of entacapone has been identified as a critical component for its potency and ability to inhibit COMT [2].
Entacapone is an FDA-approved COMT inhibitor for use as an adjunct to levodopa therapy in patients’ with Parkinson’s disease, where it increases both the peripheral and central availability of levodopa [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.
