Oxprenolol HCl (Ba-39089 hydrochloride) is a novel and potent beta blocker with intrinsic sympathomimetic activity. It can be used for the treatment of angina pectoris, abnormal heart rhythms, and high blood pressure. It can be used to treat high blood pressure, irregular cardiac rhythms, and angina pectoris. It inhibits β-adrenergic receptor (β-AR) with a Ki of 7.10 nM in a radioligand binding assay using rat heart muscle.
| Targets |
β-adrenoceptor ( Ki = 7.1 nM )

| ln Vitro |
Oxprenolol is lipophilic [3]. Oxprenolol typically penetrates human abdominal skin at a rate of 1.54 ± 1.54×10-3 cm/h[3].
|
| ln Vivo |
Oxprenolol (200 mg/kg/day; oral; once daily for 3 weeks) produces an effective beta-blocker[2].

| Enzyme Assay |
Binding characteristics of the beta-blockers and beta-agonists with the beta-adrenoceptors were investigated in 3H-dihydroalprenolol (3H-DHA) binding to rat heart membranes treated with neuraminidase. When 60% of the total sialic acid content in the membranes was removed, reproducibility of the binding assay became much better than was attainable without neuraminidase treatment, and the maximum density of beta-adrenoceptors was increased. These data suggest that the binding of the test compounds with the beta-adrenergic receptors in cardiac muscle was under the influence of the sialic acid of the glycocalyx of the membrane. The 3H-DHA binding sites in membranes treated with neuraminidase showed a strict stereo-specificity when tested with propranolol. The ranking order of inhibition of beta-antagonists or agonists is: dl-propranolol > Oxprenolol > than alprenolol > pindolol > YM-09538 > labetalol > acebutolol > atenolol > metoprolol > sotalol > butoxamine > practolol as antagonists or l-isoproterenol > l-epinephrine > l-norepinephrine as agonists. A good correlation (r = 0.91, P less than 0.001) was observed between the Ki values observed by the present binding assay and the pA2 observed in the guinea-pig atria relative to the positive inotropic effect by Bieth et al. (Br. J. Pharmacol. 68, 563-569, 1980), indicating that the present method will be useful for screening new beta-adrenergic receptor antagonists or agonists. [1]

| Additional Infomation |
Oxprenolol Hydrochloride is the hydrochloride salt form of oxprenolol, a lipophilic, nonselective beta-adrenergic receptor antagonist with anti-arrhythmic, anti-anginal and antihypertensive activities. Oxprenolol competitively binds to and blocks beta-1 adrenergic receptors in the heart, thereby decreasing cardiac contractility and rate. This leads to a reduction in cardiac output and lowers blood pressure. In addition, oxprenolol prevents the release of renin, a hormone secreted by the kidneys that causes constriction of blood vessels.
A beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety. In the present study, as a continuation of a previous one in which two β-blockers celiprolol and bisoprolol were reported (Modamio et al., 1998), transdermal permeation properties across human skin in vitro of propranolol, Oxprenolol, metoprolol and atenolol were compared (including also both celiprolol and bisoprolol), and the potential of each individual drug studied assessed. In addition, correlations between physicochemical parameters of β-blockers chosen, were established, especially lipophilicity expressed as intrinsic partition coefficient, in order to determine whether optimal permeability, and so the predictive potential of these physicochemical parameters can be established.
