Evidence for a Second Desensitized State of β‐Adrenergic Receptor with Low Affinity for β‐Antagonists and Normal Reactivity towards β‐Agonists in Adipocyte Membranes Previously Exposed to β‐Antagonists [PDF]

open access: yesEuropean Journal of Biochemistry, 1979
When adipocyte membranes are successively exposed to (−)‐propranolol or (±)‐alprenolo1 at 25 or 4°C, repeatedly washed and then assayed for (−)‐[3H]dihydroalprenolol binding, the apparent number of β‐adrenergic binding sites is markedly decreased. Induction of this peculiar type of receptor desensitization does not require prolonged exposure of the ...

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.

open access: hybridJournal 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.

Identifying Ligand Binding Conformations of the β2-Adrenergic Receptor by Using Its Agonists as Computational Probes [PDF]

open access: yes, 2011
Recently available G-protein coupled receptor (GPCR) structures and biophysical studies suggest that the difference between the effects of various agonists and antagonists cannot be explained by single structures alone, but rather that the conformational

Alpha-1 adrenergic receptor antagonists to prevent hyperinflammation and death from lower respiratory tract infection [PDF]

open access: yesElife 10 (2021): e61700, 2020
In severe viral pneumonia, including Coronavirus disease 2019 (COVID-19), the viral replication phase is often followed by hyperinflammation, which can lead to acute respiratory distress syndrome, multi-organ failure, and death. We previously demonstrated that alpha-1 adrenergic receptor ($\alpha_1$-AR) antagonists can prevent hyperinflammation and ...

Analgesic Efficacy of Perioperative Esmolol as an Adjunct to Morphine in Mastectomy- A Prospective Observational Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2021
Introduction: Multimodal analgesia with opioids as the prime component is the mainstay of postoperative analgesia for mastectomy, which can lead to many opioid related unwanted side-effects.
