Interaction of verapamil and other calcium channel blockers with alpha 1- and alpha 2-adrenergic receptors.

Circulation Research, 1983
To determine the specificity of the previously demonstrated competition of verapamil with radioligand binding to alpha-adrenergic receptors, we examined the interaction of calcium channel blockers with alpha 1- and alpha 2-adrenergic receptors on several

Phylogenomic analysis reveals extensive phylogenetic mosaicism in the Human GPCR Superfamily [PDF]

, 2007
A novel high throughput phylogenomic analysis (HTP) was applied to the rhodopsin G-protein coupled receptor (GPCR) family. Instances of phylogenetic mosaicism between receptors were found to be frequent, often as instances of correlated mosaicism and ...

Both Ligand- and Cell-Specific Parameters Control Ligand Agonism in a Kinetic Model of G Protein–Coupled Receptor Signaling [PDF]

, 2007
G protein–coupled receptors (GPCRs) exist in multiple dynamic states (e.g., ligand-bound, inactive, G protein–coupled) that influence G protein activation and ultimately response generation. In quantitative models of GPCR signaling that incorporate these

Receptor-mediated enhancement of beta adrenergic drug activity by ascorbate in vitro and in vivo. [PDF]

PLoS ONE, 2010
RATIONALE: Previous in vitro research demonstrated that ascorbate enhances potency and duration of activity of agonists binding to alpha 1 adrenergic and histamine receptors.

Neurobiological Mechanisms That Contribute to Stress-related Cocaine Use [PDF]

, 2014
The ability of stressful life events to trigger drug use is particularly problematic for the management of cocaine addiction due to the unpredictable and often uncontrollable nature of stress.

Developing New Drug Antagonist for Alpha Adrenergic Receptors for Hypertension Diseases [PDF]

, 2017
Alpha-adrenergic receptors play a vital role in the regulation of blood pressure(BP). Hypertension referred as blood pressure above the normal range. hyper tension can cause severe complications such as stroke, coronary heart disease and kidney failure ...

Evidence for the existence of vascular alpha 2-adrenergic receptors in humans.

HYPERTENSION, 1984
Many studies have suggested that alpha-adrenergic receptors on vascular smooth muscle are heterogeneous and that both alpha 1- and alpha 2-adrenergic receptors can cause vasoconstriction when stimulated.

A G protein-gated K channel is activated via beta 2-adrenergic receptors and G beta gamma subunits in Xenopus oocytes [PDF]

, 1995
In many tissues, inwardly rectifying K channels are coupled to seven- helix receptors via the Gi/Go family of heterotrimeric G proteins. This activation proceeds at least partially via G beta gamma subunits.

Regulation of rabbit myometrial alpha adrenergic receptors by estrogen and progesterone.

Journal of Clinical Investigation, 1977
The effects of estrogen and progesterone on uterine alpha-adrenergic receptors were investigated by direct receptor-binding studies. Immature female rabbits were primed with estrogen by intramuscular injections for 4 days.
