Nitecapone is S-COMT inhibitor [1].
Catechol-O-methyltransferase (COMT) plays an essential role in normal brain function and has been implicated in human disorders, such as Parkinson's disease. The COMT has been involved in the degradation of catecholamines including dopamine, epinephrine, and norepinephrine. [1].
In vitro: Nitecapone is a highly effective inhibitor of rat S-COMT with IC50 values of about 300 nM in the liver and 20 nM in the brain tissues. The Ki value in the rat liver was 23 nM. In pure recombinant COMT enzyme forms, the Ki value of nitecapone was around 1 nM [1]. Nitecapone was selective for COMT, inhibiting dopamine-β-hydroxylase, tyrosine hydroxylase, DOPA decarboxylase, and monoamine oxidase-A/B with IC50 values in the micromolar range [1].
In vivo: In rats, oral administration of nitecapone (3-30 mg/kg) in combination with levodopa and carbidopa effectively reduced 3-OMD formation and elevated serum and brain l-dopa, dopamine, DOPAC, and HVA levels. Nitecapone prevented ischemia-reperfusion injury in experimental heart surgery in rats. Nitecapone increased bicarbonate secretion from rat and human duodenum after both i.v. and intraluminal administration. High concentrations of nitecapone increased synthesis and secretion of gastric sulfomucin [1].

Working concentration: mg/ml;
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.
