Biological Activity

Description Meldonium (MET-88, Quaterin) is an inhibitor of biosynthesis of L-carnitine by gamma-butyrobetaine (GBB) hydroxylase and as a competitive inhibitor of renal carnitine reabsorption.
Targets
GBB hydroxylase [1]
In vitro
In vitro

Meldonium (40 μM) inhibits the reaction of γ-butyrobetaine hydroxylase with γ-butyrobetaine with Km and Vmax of 36.8 μM and 0.08 nmol/min/mg protein, respectively. [1]
In Vivo
In vivo

Meldonium administered orally to rats for 10 days (150 mg/kg) elicits a reduction in myocardial free camitine and long-chain acyl carnitine content by 63.7 and 74.3%, respectively. Meldonium treatment (100 mg/kg, orally) subsequent administration of isoproterenol results in a reduction in free camitine concentration by 48.7% in comparison with the rats receiving isoproterenol. A prior administration of Meldonium effectively protects the myocardium from isoproterenol-induced variations in the content of ATP and myocardial energy charge, as well as preventing a rise in creatine phosphokinase and lactic dehydrogenase activity. [1] Meldonium  (200 mg/kg) long-term treatment significantly increases the rate of insulin-stimulated glucose uptake by 35% and the expression of glucose transporter 4 (1.7-fold increase), hexokinase II (2.1-fold increase), insulin receptor proteins (2.5-fold increase) and carnitine palmitoyltransferases IA (2.2-fold increase) in mouse hearts. Meldonium long-term treatment statistically significantly decreases fed state blood glucose from 6 to 5 mM. [2] Meldonium reduces the azidothymidine-induced alterations in mouse brain tissue. Meldonium (50 mg/kg) normalizes the increase in caspase-3, cellular apoptosis susceptibility protein (CAS) and iNOS expression. Meldonium also normalizes the changes in cytochromec oxidase (COX) expression, reduces the expression of glial fibrillary acidic protein (GFAP) and cellular infiltration. [3] Meldonium displays protective effects in experimental model of type 2 diabetes in Goto-Kakizaki rats. Meldonium (200 mg/kg) treatment decreases both the fed- and fasted-state blood glucose. Meldonium strongly inhibits fructosamine accumulation and loss of pain sensitivity (by 75%) and also ameliorates the enhanced contractile responsiveness of Goto-Kakizaki rat aortic rings to phenylephrine. In addition, in Meldonium-treated hearts, the necrosis zone following coronary occlusion is significantly decreased by 30%. [4]

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.
