Biological Activity

Description Repaglinide (AG-EE 623 ZW) is a potassium channel blocker, which lowers blood glucose by stimulating the release of insulin from the pancreas, used the treatment of type II diabetes.
Potassium channel [1]
In vitro

Repaglinide is found to bind with low affinity (K(D)=59 nM) to SUR1 alone, but with high affinity (increased approximately 150-fold) when SUR1 is co-expressed with Kir6.2. Repaglinide binds with low affinity (K(D)=51 nM) to SUR1 co-expressed with Kir6.2DeltaN14. [1] Repaglinide lowers the plasma glucose concentration in the control rat, whilst failing to affect significantly the plasma insulin concentration or insulin/glucose ratio. Repaglinide administration affects neither plasma glucose nor insulin concentration, restores a normal value for the otherwise abnormally high basal insulin output, increases the 16.7 mM/2.8 mM ratio for insulin release, and again augmented protein biosynthesis at both low and high hexose concentrations in Goto-Kakizaki (GK) rats. [2] Repaglinide is found to bind to NCS proteins, but not to CaM or S100 proteins, in a Ca2+-dependent manner. Repaglinide antagonizes the inhibitory action of recoverin in a rhodopsin kinase assay with IC50 values of 400 mM. Repaglinide tightly binds to the visinin-like domain of CCaMK and PpCaMK in a Ca2+-dependent manner and antagonizes the regulatory function of the domain with IC50 values of 55 and 4 mM for CCaMK and PpCaMK respectively. [3]

In vivo Repaglinide provokes a greater and more rapid increase in plasma insulin concentration and an earlier fall in glycemia than those observed after administration of the hypoglycemic sulfonylureas in both fed and starved normal rats. [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.
