rac-7-hydroxy Propranolol (hydrochloride) is a ring-hydroxylated isomer and metabolite of propranolol that is an antagonist at β-adrenergic receptors (0.95 potency relative to propranolol). It also demonstrates potent vasodilator activity (0.20 potency relative to propranolol; pA2 = 7.58).
(±)-4-hydroxy Propranolol β-D-glucuronide is a metabolite of (±)-4-hydroxy propranolol , which is a metabolite of propranolol. The apparent half-life of (±)-4-hydroxy propranolol β-D-glucuronide is similar to propranolol and 4-hydroxy propranolol. Propranolol is a β-adrenergic antagonist, and the active enantiomer, (S)-(-)-propranolol , has log Kd values of -8.16, -9.08, and -6.93 for β1, β2, and β3, respectively.
Propranolol D7 hydrochloride is a deuterium labeled Propranolol hydrochloride. Propranolol hydrochloride is a nonselective antagonist of β-adrenergic receptor (βAR).
5-hydroxy Propranolol is a metabolite of propranolol , a β-adrenergic receptor antagonist. Propranolol is primarily metabolized in the liver, with cytochrome P450 isoform 2D6 directing ring hydroxylation and the generation of 5-hydroxy propranolol and related metabolites.
4-Hydroxypropranolol hydrochloride is an active metabolite of Propranolol, with a potency comparable to Propranolol. It inhibits β1- and β2-adrenergic receptors (pA2s: 8.24 and 8.26).
4-Hydroxypropranolol D7 hydrochloride is deuterium-labeled 4-Hydroxypropranolol hydrochloride. 4-Hydroxypropranolol hydrochloride is an active metabolite of Propranolol, with a potency comparable to Propranolol. It inhibits β1- and β2-adrenergic receptors
Bupranolol is a non-selective beta blocker without intrinsic sympathomimetic activity (ISA), but with strong membrane stabilizing activity. Its potency is similar to propranolol. Bupranolol is quickly and completely absorbed from the gut. Over 90% undergo first-pass metabolism. Bupranolol has a plasma half life of about two to four hours, with levels never reaching 1 µg l in therapeutic doses. The main metabolite is carboxybupranolol, 4-chloro-3-[3-(1,1-dimethylethylamino)-2-hydroxy-propyloxy]benzoic acid – that is, the methyl group at the benzene ring is oxidized to a carboxyl group –, of which 88% are eliminated renally within 24 hours.
