Furosemide reversibly alters the responses to tones and clicks of the chinchilla basilar membrane in hair cells, causing response-magnitude reductions that are largest (up to 61 dB, averaging 25-30 dB) at low stimulus intensities at the characteristic frequency (CF) and small or nonexistent at high intensities and at frequencies far removed from CF. Furosemide also induces response-phase lags that are largest at low stimulus intensities (averaging 77 degrees) and are confined to frequencies close to CF. [1] Furosemide concentration- and time-dependently increases the formation of nitric oxide andprostacyclin. Furosemide leads to an enhanced release of kinins into the supernatant of the cells. [2] Furosemide reversibly suppresses low Ca2+-induced epileptiform activity in hippocampus proper and blocks or significantly reduces different types of epileptiform discharges in the low Mg2+ model and the 4-aminopyridine model. [3] Furosemide significantly inhibits cell growth in MKN45 cells, but not in MKN28 cells. Furosemide diminishes cell growth by delaying the G(1)-S phase progression in poorly differentiated gastric adenocarcinoma cells, which show high expression and activity of NKCC, but not in moderately differentiated gastric adenocarcinoma cells with low expression and NKCC activity.

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
