Biological Activity

Description Propranolol HCl (AY-64043, ICI-45520, NCS-91523) is a competitive non-selective beta-adrenergic receptors inhibitor with IC50 of 12 nM.
β-adrenergic receptor [1]
12 nM
In vitro

Propranolol, a non-selective β1 and β2 adrenergic blocker, has no effect on the proliferation of neonatal mouse cardiac fibroblasts (NMCFs).[2]

In vivo

Propranolol, an anti-arrhythmic drugs, consistently reduces the heart rates of adult mice by approximately 10%-20%, whereas isoproterenol has the opposite effect.[2]

Protocol (from reference)

Cell Research:


  • Cell lines: neonatal mice cardiomyocytes (NMCMs)
  • Concentrations: 10, 20, 40, 50, and 100 μM
  • Incubation Time: 6, 12, 18, and 24 h
  • Method:

    In vitro, the neonatal mice cardiomyocytes (NMCMs) are treated with different drugs of different concentration, including isoproterenol (0, 1, 2.5, 5, 10, 20, and 50 μM); amiodarone (0, 1, 2.5, 5, 10, 20, and 50 μM); metoprolol (0, 10, 20, 30, 50, 100, 150, and 200 μM); propranolol (0, 10, 20, 40, 50, and 100 μM); lidocaine (0, 1, 2.5, 5, 10, 20, and 50 μM); verapamil(0, 1, 2.5, 5, 10, 20, and 50 μM);ivabradine (0, 1, 2, 3, 5, 10, and 20 μM). And the concentrations of drugs that promote CMs proliferation most significantly are chosen for subsequent experiments, including isoproterenol (10 μM), amiodarone (5 μM), metoprolol (20 μM), propranolol (20 μM), lidocaine (5 μM), verapamil (2.5 μM), ivabradine (3 μM) for NMCMs, NMCFs, and hPSC-CM.

Animal Research:


  • Animal Models: 1-day-old neonatal mice; 12-week-old adult mice
  • Dosages: 10 mg/kg/d
  • Administration: s.c.; ALZET Osmotic Pumps

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.
