Background:

(±)-Nebivolol-d₄is intended for use as an internal standard for the quantification of nebivolol by GC- or LC-MS. Nebivolol is a potent and selective β₁-adrenergic receptor (β₁-AR) antagonist (IC₅₀s = 7.41 and 251 nM for β₁- and β₂-ARs, respectively, in a radioligand binding assay using rabbit lung membrane preparations).¹It is also selective for β₁-ARs over serotonin 5-HT_1Aand 5-HT₂, α₁- and α₂-adrenergic, histamine H₁, and dopamine D₂receptors (IC₅₀s = 27.5 and 2,239, 3,162 and >10,000, 5,623, and 10,000 nM, respectively). Nebivolol inhibits cAMP accumulation induced by norepinephrine in primary rat cardiac cells (IC₅₀= 22 nM) and induces vasodilation in mouse renal arteriesviaa nitric oxide- and cGMP-dependent mechanism (EC₅₀= 11.36 μM).^2,3It decreases contraction of isolated human left ventricular trabeculae induced by isoproterenol but does not exert intrinsic sympathomimetic activity (ISA).⁴Nebivolol inhibits proliferation of human coronary artery smooth muscle cells (HCASMCs) in the presence and absence of growth factors (IC₅₀s = 6.1, 6.8, 6.4, and 7.7 μM for HCASMCs grown in media containing no growth factor, PDGFBB, basic FGF, and TGF-β1, respectively).⁵Formulations containing nebivolol have been used to treat hypertension.
