Biological Activity

Description Milrinone is a phosphodiesterase 3 (PDE3) inhibitor, used to increase the heart's contractility.
Targets
ATPase [1] PDE3 [7] PDE2 [7]
2.1 μM 5.2 μM
In vitro

Milrinone causes a concentration-dependent increase in the cAMP level in rabbit and human platelets with similar potency. Milrinone inhibits human platelet aggregation with a median inhibitory concentration (IC50) of 2 mM.Milrinone concentration-dependently increases left ventricular developed pressure (LVDP) and contractility. Milrinone concentration-dependently increases cAMP in rabbit coronary smooth muscle cells. [1] Milrinone increases intracellular cyclic adenosine monophosphate by inhibiting Type III phosphodiesterase. [2] Milrinone is a potent (IC50 = 0.16-0.90 mM) and selective (100 times peak III relative to peak I) peak III inhibitor. Milrinone significant increases in cAMP content accompany significant vasorelaxation. [3]

In vivo Milrinone inhibits PDE4 in addition to PDE3 activity in the rabbit heart.Milrinone (>10 microM) causes greater elevations in intracellular cAMP and calcium than cilostazol. [4] Milrinone causes similar increases in heart rate, cardiac output, and left ventricular +dP/dt and decreases in end-diastolic pressure and systemic vascular resistance in anaesthetized dogs. [5] Milrinone leads to significant increases in right ventricular function as well as significant improvements in pulmonary vascular resistance, pulmonary blood flow, and left ventricular filling in mongrel dogs underwent pulmonary artery catheterization.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

    Molecular Weight

*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

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 )

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.
