α1b-Adrenergic Receptors Control Locomotor and Rewarding Effects of Psychostimulants and Opiates

Journal of Neuroscience, 2002
Drugs of abuse, such as psychostimulants and opiates, are generally considered as exerting their locomotor and rewarding effects through an increased dopaminergic transmission in the nucleus accumbens.

The Allosteric Mechanism of G‐Protein‐Coupled Receptors is Induced Fit, Not Conformational Selection

BioEssays, EarlyView.
Allosteric signaling of G‐protein‐coupled receptors (GPCRs) involves a population shift from inactive to active receptor conformations upon binding of ligand agonists. Kinetic and structural data indicate that this population shift is induced by ligand binding to inactive receptor conformations prior to the conformational change from inactive to active.

Synephrine, a Component of Evodiae Fructus, Constricts Isolated Rat Aorta via Adrenergic and Serotonergic Receptors

Journal of Pharmacological Sciences, 2009
We investigated the effects of Evodiae Fructus and synephrine, one of the components of Evodiae Fructus, on blood vessels. We found that Evodiae Fructus (1 × 10−4 g/mL) had constrictive effects on rat aorta.

Endothelium‐Independent Relaxation of Alkaloid Boldine in Isolated Aortas From Normotensive and Hypertensive Rats: Participation of Ca2+ Channels

Chemistry &Biodiversity, EarlyView.
Involvement of Ca2+ channels in boldine‐induced vascular relaxation. ABSTRACT The regulation of vascular tone plays a fundamental role in blood pressure homeostasis and still represents a significant challenge in clinical practice. Boldine, a naturally occurring alkaloid from Peumus boldus, has emerged as a compound of interest due to its therapeutic ...
