Safety and efficacy of beta-3 adrenergic agonists in treating neurogenic lower urinary tract dysfunction: A systematic review and meta-analysis [PDF]

Investigative and Clinical Urology
Purpose: To evaluate efficacy and safety of beta-3 adrenergic agonists in adults with neurogenic lower urinary tract dysfunction. Materials and Methods: According to a protocol (CRD42022350079), we searched multiple data sources for published and ...

Inverted Variant of Takotsubo Syndrome Caused by Inhaled Adrenergic Beta-2 Agonists

European Journal of Case Reports in Internal Medicine, 2018
Takotsubo syndrome (TS) is an acute and reversible clinical syndrome characterized by transient hypokinesis of the left ventricular (LV) apex. Variant forms of LV dysfunction have been reported, including inverted Takotsubo syndrome (ITS), which ...

Trafficking of β2-adrenergic receptors: insulin and β-agonists regulate internalization by distinct cytoskeletal pathways [PDF]

Journal of Cell Science, 2004
Insulin and β-adrenergic agonists stimulate a rapid phosphorylation and sequestration of the β2-adrenergic receptors (β2ARs). Although the expectation was that a common pathway would be involved in the trafficking of the β2AR in response to either hormone, studies reported herein show the existence of unique cytoskeletal requirements for ...

An assay for beta-adrenergic receptors in isolated human fat cells.

Journal of Lipid Research, 1982
The beta-adrenergic receptors have been characterized in isolated human adipocytes using a potent beta-adrenergic antagonist (-)-[3H]dihydroalprenolol.

Evidence from in vitro differentiating cells that adrenoceptor agonists can increase uncoupling protein mRNA level in adipocytes of adult humans: an RT-PCR study

Journal of Lipid Research, 1996
In vivo data have suggested that adrenergic signals can reactivate dormant brown adipocytes in adult humans. We report here a system based on primary cultures of perirenal adipocytes from human adults and reverse transcription-PCR of uncoupling protein ...

Time-dependent decreases in binding affinity of agonists for beta-adrenergic receptors of intact S49 lymphoma cells. A mechanism of desensitization.

Journal of Biological Chemistry, 1983
Studies of beta-adrenergic receptors on several types of intact target cells indicate that agonists, but not antagonists, show prominent KD/Kact discrepancies--lower affinities (KD) in equilibrium binding studies (i.e.

Chirality of β2-agonists. An overview of pharmacological activity, stereoselective analysis, and synthesis

Open Chemistry, 2020
β2-Agonists (β2-adrenergic agonists, bronchodilatants, and sympathomimetic drugs) are a group of drugs that are mainly used in asthma and obstructive pulmonary diseases. In practice, the substances used to contain one or more stereogenic centers in their

Prolonged β-Agonist Infusion Does Not Induce Desensitization or Down-Regulation of β-Adrenergic Receptors in Newborn Sheep [PDF]

Pediatric Research, 1992
In adult animals, prolonged beta-agonist exposure leads to down-regulation of beta-adrenergic receptors and desensitization. Prior evidence from our lab suggests that this may not occur in developing animals. To study this, we measured the response to graded epinephrine infusion [2.7, 5.5, 13.6, 27.3 mumol/(kg.min), (0.5, 1.0, 2.5, 5.0 micrograms/(kg ...

Functional activation of beta-adrenergic receptors by thiols in the presence or absence of agonists.

Journal of Biological Chemistry, 1985
Treatment of beta-adrenergic receptor with dithiothreitol (DTT) or other thiol compounds caused its functional activation in the presence or absence of agonist ligands.
