Propranolol hydrochloride (b)

Propranolol Hydrochloride is a widely used non-cardioselective beta-adrenergic antagonist. (In Vitro) :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.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.Propranolol hydrochloride (50 μM-200 μM; 24 hours) increases Annexin V positivity and caspase-3 activation, rapidly induces HemSC apoptosis. (In Vivo) :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.
