Mrtoprolol is a beta-adrenergic receptor blocking agent. In vitro and in vivo animal studies have shown that it has a preferential effect on beta-1 adrenoreceptors, chiefly located in cardiac muscle. Clinical pharmacology studies have confirmed the beta-blocking activity of metoprolol in man, as shown by (1) reduction in heart rate and cardiac output at rest and upon exercise, (2) reduction of systolic blood pressure upon exercise, (3) inhibition of isoproterenol-induced tachycardia, and (4) reduction of reflex orthostatic tachycardia. Mrtoprolol is indicated for the treatment of hypertension, angina pectoris and myocardial infarction

Dobutamine is a sympathomimetic drug used in the treatment of heart failure and cardiogenic shock. Dobutamine hydrochloride is a direct-acting inotropic agent whose primary activity results from stimulation of the ß-receptors of the heart while producing comparatively mild chronotropic, hypertensive, arrhythmogenic, and vasodilative effects. It does not cause the release of endogenous norepinephrine, as does dopamine. Dobutamine directly stimulates beta-1 receptors of the heart to increase myocardial contractility and stroke volume, resulting in increased cardiac output. Dobutamine Injection, USP is indicated when parenteral therapy is necessary for inotropic support in the short-term treatment of adults with cardiac decompensation due to depressed contractility resulting either from organic heart disease or from cardiac surgical procedures.

Droxidopa (Northera, Chelsea Therapeutics) is a synthetic catecholamino acid precursor of norepinephrine indicated for the treatment of orthostatic dizziness or lightheadedness in adult patients with symptomatic neurogenic orthostatic hypotension (NOH) caused by primary autonomic failure, dopamine beta-hydroxylase deficiency, and non-diabetic autonomic neuropathy. Droxidopa was approved as oral therapy in February 2014 under the FDA’s accelerated approval program. Droxidopa is directly metabolized to norepinephrine by dopadecarboxylase. The specific mechanism of action of the drug is not known completely, but it is supposed to exert the pharmacological effects through norepinephrine and not through the parent molecule or other metabolites. It increases blood flow to the brain by stimulating peripheral arterial and venous vasoconstriction.

Amibegron (SR 58611A or SR 58611) is a highly selective agonist for atypical beta3-adrenoceptors. It stimulates neuronal activity in a specific area of the prefrontal cortex and also inhibits intestinal motility. Amibegron was in phase III trials worldwide for the treatment of depression and generalised anxiety disorder but development of the product was discontinued in 2008. Amibegron has been tested for its potential as a treatment for irritable bowel syndrome.

Nacubactam (FPI-1459) was developed as an antibacterial drug. Nacubactam successfully has completed phase I clinical trials for the treatment of serious gram-negative bacterial infections. The drug is currently being developed for the treatment of complicated urinary tract infection, hospital-acquired bacterial pneumonia, ventilator-associated bacterial pneumonia, and complicated intra-abdominal infections. FPI-1459 works through several mechanisms of action, inhibiting a number of beta-lactamase enzymes as well as certain bacterial cell wall enzymes. In January 2019, FPI-1459 received Fast Track and Qualified Infectious Disease Product designations from the U.S. Food and Drug Administration (FDA).

7β-hydroxycholesteryl-3-oleate has been shown to inhibit astrogliosis and intracranial glioblastoma growth. Local administration of 7β-hydroxycholesteryl-3-oleate inhibits growth of experimental rat C6 glioblastoma. These data suggest that 7β-hydroxycholesteryl-3-oleate might be useful for local glioblastoma chemotherapy. 7β-hydroxycholesteryl-3-oleate is a potent inhibitor of the endogenous cholesterol biosynthesis in brain showing a correlation between cholesterogenesis and reactive astrocyte proliferation. 7β-hydroxycholesteryl-3-oleate can reduce the astrocytic reaction following spinal cord injury, promoting the serotonergic reinnervation of a denervated territory. On 17 December 2010, orphan designation (EU/3/10/816) was granted by the European Commission to Intsel Chimos SA, France, for 7-beta-hydroxy cholesteryl-3-beta-oleate for the treatment of glioma. The substance is going to be injected directly into the brain tumour contained within liposomes, which are expected to carry the medicine into the glioma cells.
