EPINEPHRINE INHIBITS THE A CTIVITY OF PHOSPH ATIDATE PHOSPHOHYDROLASE OF ISOLATED HUMA N HEPATOCYTES
The effect of epinephrine on phosphatidate phosphohydrolase (PAP) activity of isolated human hepatocytes was studied. Epineprine inhibited the enzyme activity progressively at concentrations above 0.1 µM, reaching a maximum inhibition of 64.5% at 100 µM concentration. Inclusion of alprenolol, a β-receptor blocker, in the incubation mixture abolished the inhibitory effect of epinephrine on P...
Abediterol is a novel potent, long-acting inhaled β(2)-adrenoceptor agonist in development for the treatment of asthma and chronic obstructive pulmonary disease. Abediterol shows subnanomolar affinity for the human β(2)-adrenoceptor and a functional selectivity over β(1)-adrenoceptors higher than that of formoterol and indacaterol in both a cellular model with overexpressed human receptors and ...
Cold allodynia is an important distinctive feature of neuropathic pain. The present study examined whether single or repetitive treatment of diluted bee venom (DBV) reduced cold allodynia in sciatic nerve chronic constriction injury (CCI) rats and whether these effects were mediated by spinal adrenergic receptors. Single injection of DBV (0.25 or 2.5 mg/kg) was performed into Zusanli acupoint 2...
The growing practice of exploiting noninvasive fluorescence-based techniques to study G protein-coupled receptor pharmacology at the single cell and single molecule level demands the availability of high-quality fluorescent ligands. To this end, this study evaluated a new series of red-emitting ligands for the human β-adrenoceptor family. Upon the basis of the orthosteric ligands propranolol, a...
rysms associated with human immunodeficiency virus (HIV) infection. β 2-adrenoceptor agonists have long been widely used for the management of certain conditions, including chronic obstructive pulmonary disease (COPD). However, in recent years, sudden cardiac death (SCD) associated with the use of β 2-adrenoceptor agonists has raised significant concerns about the safety profile of these agents...
Adrenergic receptor (AR)-mediated signalling is modulated by oxygen levels. Prolyl hydroxylases (PHDs) are crucial for intracellular oxygen sensing and organism survival. However, it remains to be clarified whether or how PHDs are involved in the regulation of β(2) -adrenoceptor (β(2) -AR) signalling. Here we show that PHD2 can modulate the rate of β(2) -AR internalization through interactions ...
