WebJun 22, 2024 · Binol is a β-adrenergic receptor blocking agent. Binol is a racemate of two enantiomers, d-Binol and l-Binol. Binol exhibits high selectivity for β1-adrenergic receptors and has vasodilating activity due to a direct action on the endothelium, involving nitric oxide release. It lacks intrinsic sympathomimetic and membrane-stabilising activity. WebApr 6, 2011 · Summary. This chapter contains sections titled: Introduction. Applications in Reduction and Oxidation.
