Abstract 1. There is considerable interest in novel therapies for cough, since currently used agents such as codeine have limited beneficial value due to the associated side effects. Sensory nerves…
Condition: Endocannabinoid System (ECS)
The Endocannabinoid-CB Receptor System: Importance for development and in pediatric disease
Abstract Endogenous cannabinoids (endocannabinoids) and their cannabinoid CB1 and CB2 receptors, are present from the early stages of gestation and play a number of vital roles for the developing organism….
The diverse CB1 and CB2 receptor pharmacology of three plant cannabinoids: D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin
Cannabis sativa is the source of a unique set of compounds known collectively as plant cannabinoids or phytocannabinoids. This review focuses on the manner with which three of these compounds,…
Agonistic Properties of Cannabidiol at 5-HT1a Receptors
Cannabidiol (CBD) is a major, biologically active, but psycho-inactive component of cannabis. In this cell culture-based report, CBD is shown to displace the agonist, [3H]8-OHDPAT from the cloned human 5-HT1a…
Allosteric Modulation of the Cannabinoid CB1 Receptor
We investigated the pharmacology of three novel compounds, Org 27569 (5-chloro-3-ethyl-1H-indole-2-carboxylic acid [2-(4- piperidin-1-yl-phenyl)-ethyl]-amide), Org 27759 (3-ethyl-5- fluoro-1H-indole-2-carboxylic acid [2-94-dimethylamino-phenyl)-ethyl]-amide), and Org 29647 (5-chloro-3-ethyl-1H-indole2-carboxylic acid (1-benzyl-pyrrolidin-3-yl)-amide, 2-enedioic acid salt), at…
Anandamide and 2-arachidonoylglycerol: Pharmacological Properties, Functional Features, and Emerging Specificities of the Two Major Endocannabinoids
Since the discovery of endocannabinoids and their receptors, two major members of the endocannabinoid family, anandamide (AEA) and 2-arachidonoylglycerol (2-AG), have been regarded almost as twin brothers. Pharmacological properties were…
Antiangiogenic Activity of the Endocannabinoid Anandamide: Correlation to its Tumor-Suppressor Efficacy
Endocannabinoids are now emerging as suppressors of key cell-signaling pathways involved in cancer cell growth, invasion, and metastasis. We have previously observed that the metabolically stable anandamide analog, 2-methyl-2′-F-anandamide (Met-F-AEA)…
Biphasic Effects of Cannabinoids on Acetylcholine Release in the Hippocampus: Site and Mechanism of Action
Cannabinoids have been shown to critically modulate cholinergic neurotransmission in the hippocampus, yet opposing effects of cannabinoid receptor 1 (CB1R) agonists on hippocampal synaptic acetylcholine (ACh) efflux have been reported….
Cannabidiol displays unexpectedly high potency as an antagonist of CB1 and CB2 receptor agonists in vitro
Background and purpose: A nonpsychoactive constituent of the cannabis plant, cannabidiol has been demonstrated to haveĀ low affinity for both cannabinoid CB1 and CB2 receptors. We have shown previously that…
Cannabidiol is a negative allosteric modulator of the type 1 cannabinoid receptor
Background and purpose: Cannabidiol has been reported to act as an antagonist of cannabinoid agonists at type 1 cannabinoid receptors (CB1). We hypothesized that cannabidiol can inhibit cannabinoid agonist activity…
