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 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. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
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 MSDS / 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 MSDS / 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.
