Concentration-dependent effects of nicorandil to protect against stress and recovery (S/R)-induced cell injury and reactive oxygen species (ROS) production in nonaffected induced pluripotent stem cell (iPSC)-derived cardiomyocytes. The N-iCMs were subjected to 2 hours of oxidative stress followed by recovery. Protective effects of different concentrations of nicorandil (0.1, 1, 10, and 100 μmol/L) on cell injury and ROS production were assessed after 4 hours of recovery by measuring lactate dehydrogenase (LDH) release into the supernatant and evaluating dihydroethidium (DHE) fluorescent intensity, respectively. A, Stress induces an increase in LDH release in N-iCMs, which is mitigated by 10 and 100 μmol/L nicorandil but not 0.1 and 1 μmol/L. B, Stress induced an increase in ROS levels as indicated by DHE fluorescence, which is abolished by 10 and 100 μmol/L nicorandil but not 0.1 and 1 μmol/L. Data are mean ± standard error of the mean (SEM) of values from 3 independent experiments (n = 3/group). *P ≤ .05 versus control.

|Description||Nicorandil (SG-75) is a potassium channel activator, and stimulates guanylate cyclase to increase formation of cyclic GMP (cGMP).|
Nicorandil (100 mM) increases Flavoprotein oxidation but not membrane current; a 10-fold higher concentration recruits both mitoK(ATP) and surfaceK(ATP) channels. Nicorandil bluntes the rate of cell death in a pelleting model of ischemia; this cardioprotective effect is prevented by the mitoK(ATP) channel blocker 5-hydroxydecanoate but is unaffected by the surfaceK(ATP) channel blocker HMR1098.  Nicorandil (100 mM) suppresses TUNEL positivity, cytochrome c translocation, caspase-3 activation and dissipation of mitochondrialinner membrane potential (Delta(Psi)(m)). Nicorandil prevents Delta(Psi)(m) depolarization in a concentration-dependent manner (EC(50) approximately 40 mM, with saturation by 100 mM), as shown by fluorescence-activated cell sorter analysis of cells stained with a fluorescent Delta(Psi)(m)-indicator, tetramethylrhodamine ethyl ester (TMRE).  Nicorandil activates a weakly inwardly-rectifying, glibenclamide-sensitive 80 pS K+ channel in both the transfected cells. Nicorandil preferentially activates the K(ATP) channels containing SUR2B in HEK293T cells.  Nicorandil (100 mM) significantly suppresses the number of cells with TUNEL-positive nuclei and the increase in caspase-3 activity induced by 20 mM H2O2. Nicorandil prevents the loss of DeltaPsim induced by H2O2 in a concentration-dependent manner. 
|In vivo||Nicorandil (2.5 mg/kg daily, p.o.) combined with Amlodipine (5.0 mg/kg daily, p.o.) for 3 days significantly prevents these alterations and restored the enzyme activities to near normal in rats. |

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
