Beta-Adrenergic Agonists [PDF]

Pharmaceuticals, 2010
Inhaled β2-adrenoceptor (β2-AR) agonists are considered essential bronchodilator drugs in the treatment of bronchial asthma, both as symptoms-relievers and, in combination with inhaled corticosteroids, as disease-controllers.

Functional alteration of the beta-adrenergic receptor during desensitization of mammalian adenylate cyclase by beta-agonists. [PDF]

Proceedings of the National Academy of Sciences, 1984
Exposure of several mammalian cell lines to isoproterenol resulted in a desensitization of the beta-adrenergic receptor-adenylate cyclase system in membranes isolated from the cells. Under the experimental conditions chosen, desensitization was accompanied by a minimal loss of beta-receptors.

High-affinity binding of agonists to beta-adrenergic receptors on intact cells. [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 1983
The interactions of agonists and antagonists with beta-adrenergic receptors on intact 1321N1 human astrocytoma and C62B rat glioma cells were studied by using the radioligand (-)-[125I]iodopindolol. Competition binding assays were performed at 37 degrees

LBMON186 Beta-agonist Profiling Reveals Novel Biased Signaling Phenotypes For The Beta 2-adrenergic Receptor With Implications In The Treatment Of Asthma [PDF]

Journal of the Endocrine Society, 2022
Abstract Asthma involves chronic airway inflammation and airway smooth muscle (ASM) cell contraction. Treatment include agonists of the beta 2-AR, a GPCR that induces the Gs/cAMP pathway leading to ASM relaxation. These agonists can also promote severe side effects which have been correlated with beta-arrestins (barr) activation ...

Desensitization of beta-adrenergic receptors by beta-adrenergic agonists in a cell-free system: resensitization by guanosine 5'-(beta, gamma-imino)triphosphate and other purine nucleotides.

Proceedings of the National Academy of Sciences of the United States of America, 1976
Incubation of purified frog erythrocyte membranes with beta-adrenergic agonists at 25 degrees produces relatively rapid (half-time about 10 min) desensitization (inactivation) of about 60% of the beta-adrenergic receptor binding sites.

Human fat cell beta-adrenergic receptors: beta-agonist-dependent lipolytic responses and characterization of beta-adrenergic binding sites on human fat cell membranes with highly selective beta 1-antagonists.

Journal of Lipid Research, 1988
Beta-adrenergic receptors were characterized in human fat cell membranes using 125I-labeled cyanopindolol (125I-labeled CYP) and highly selective beta 1-antagonists. The iodinated radioligand bound saturably and specifically to a single class of high affinity binding sites.

Beta-agonist- and prostaglandin E1-induced translocation of the beta-adrenergic receptor kinase: evidence that the kinase may act on multiple adenylate cyclase-coupled receptors.

Proceedings of the National Academy of Sciences, 1986
beta-Adrenergic receptor kinase (beta-AR kinase) is a cytosolic enzyme that phosphorylates the beta-adrenergic receptor only when it is occupied by an agonist [Benovic, J. Strasser, R. H., Caron, M. G. & Lefkowitz, R. J. (1986) Proc. Natl. Acad. Sci.

Modulation of in vitro erythropoiesis. The influence of beta-adrenergic agonists on erythroid colony formation. [PDF]

Journal of Clinical Investigation, 1977
Canine marrow erythroid colony growth is enhanced by agents linked to the adenyl cyclase/cyclic AMP (cAMP) system, including cAMP, a phosphodieterase inhibitor (RO-20-1724), cholera enterotoxin, and beta-adrenergic agonists.
