An Alpha-1A Adrenergic Receptor Agonist Prevents Acute Doxorubicin Cardiomyopathy in Male Mice. [PDF]

PLoS ONE, 2017
Alpha-1 adrenergic receptors mediate adaptive effects in the heart and cardiac myocytes, and a myocyte survival pathway involving the alpha-1A receptor subtype and ERK activation exists in vitro. However, data in vivo are limited.

Effect of preoperative administration of systemic alpha-2 agonists on postoperative pain: a systematic review and meta-analysis [PDF]

Anesthesia and Pain Medicine, 2020
Background Alpha-2 agonists have sedative, analgesic, and opioid-sparing effects. Moreover, intraoperative or postoperative systemic administration of alpha-2 adrenergic agonists is known to reduce postoperative pain and opioid consumption.

Inhibition of the lipolytic action of beta-adrenergic agonists in human adipocytes by alpha-adrenergic agonists.

Journal of Lipid Research, 1981
The aim of this study was to define the role of the alpha-adrenergic receptor in the regulation of lipolysis by human adipocytes. Glycerol production by isolated human adipocytes was stimulated by the pure beta-adrenergic agonist isoproterenol in a dose ...

Adjuvant dexmedetomidine in treatment of alcohol withdrawal delirium: Case series

Medical Journal of Dr. D.Y. Patil Vidyapeeth, 2023
Alcohol withdrawal delirium is a medical emergency with mortality rates of 20–50% without treatment. Benzodiazepines (BZDs) (gamma-aminobutyric acid receptor agonists) are the mainstay of treatment.

Evaluation of Dexmedetomidine as an Adjuvant to Intrathecal Bupivacaine in Infraumbilical Surgeries [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: Various adjuvants like morphine, buprenorphine and fentanyl, clonidine, ketamine are being used in anaesthetic practice since long for improvement of peri-operative analgesia following spinal anaesthesia. Such adjuvants have been helpful

Preliminary evaluation of the efficacy and safety of brimonidine for general anesthesia

BMC Anesthesiology, 2021
Background To determine the hypnotic and analgesic effects of brimonidine, and evaluate its efficacy and safety for general anesthesia. Potentiation of pentobarbital sleeping time following brimonidine administration was observed in mice, as was the ...

Interactions of Agonists with Platelet α₂-Adrenergic Receptors [PDF]

Endocrinology, 1982
Epinephrine induces human platelet aggregation by interacting with alpha-adrenergic receptors. These sites were demonstrated by radioligand-binding techniques using the new antagonist ligand, [3H]yohimbine. The sites labeled by [3H]yohimbine had the specificity of alpha 2-receptors with the affinity of yohimbine much greater than prazosin.

Alpha-2-adrenergic receptor agonists for the prevention of delirium and cognitive decline after open heart surgery (ALPHA2PREVENT): protocol for a multicentre randomised controlled trial

BMJ Open, 2022
Introduction Postoperative delirium is common in older cardiac surgery patients and associated with negative short-term and long-term outcomes. The alpha-2-adrenergic receptor agonist dexmedetomidine shows promise as prophylaxis and treatment for ...

Alpha-2 Adrenergic Receptor Agonists Block Stress-Induced Reinstatement of Cocaine Seeking [PDF]

Neuropsychopharmacology, 2000
The alpha-2 adrenergic receptor agonists, clonidine, lofexidine and guanabenz, blocked stress- but not cocaine-induced reinstatement of cocaine seeking at doses that suppressed footshock-induced release of noradrenaline in prefrontal cortex and amygdala.

Agonist-dependent phosphorylation of the alpha 2-adrenergic receptor by the beta-adrenergic receptor kinase.

Journal of Biological Chemistry, 1987
Desensitization of the beta-adrenergic receptor, a receptor which is coupled to the stimulation of adenylate cyclase, may be regulated via phosphorylation by a unique protein kinase. This recently discovered enzyme, known as the beta-adrenergic receptor kinase, only phosphorylates the agonist-occupied form of the beta-adrenergic receptor.
