Propranolol hydrochloride is a nonselective β-adrenergic receptor (βAR) antagonist, has high affinity for the β1AR and β2AR with Ki values of 1.8 nM and 0.8 nM, respectively[1]. Propranolol hydrochloride inhibits [3H]-DHA binding to rat brain membrane preparation with an IC50 of 12 nM[2]. Propranolol hydrochloride is used to control hypertension, pheochromocytoma, myocardial infarction, cardiac arrhythmias, angina pectoris, and hypertrophic cardiomyopathy[3].
Propranolol hydrochloride (10-7 M-10-3 M; 24 and 48 hours) increases the total ERK1/2 levels in a dose-dependent manner, and ERK1/2 activation is observed specifically at 10-5 M in HemSCs[4].Propranolol hydrochloride (10-9 M-10-3 M; 24 and 48 hours) significant decreases cell proliferation at 10-4 M propranolol after 24 hours and 10-9 M propranolol after 48 hours in HemSCs[4].Propranolol hydrochloride (50 μM-200 μM; 24 hours) increases Annexin V positivity and caspase-3 activation, rapidly induces HemSC apoptosis[4].
Propranolol hydrochloride (orally administration; 40 mg/kg; daily) significantly reduces the vessel diameter relative to the vehicle-treated implants, and increases the number of cells that expressed phosphorylated ERK1/2 within the IH Matrigel implant[4].
