Reinforcing effects of opioid/cannabinoid mixtures in rhesus monkeys responding under a food/drug choice procedure.

Cannabinoid receptor agonists such as delta-9-tetrahydrocannabinol (Δ-THC) enhance the antinociceptive potency of mu opioid receptor agonists such as morphine, indicating that opioid/cannabinoid mixtures might be effective for treating pain. However, such enhancement will be beneficial only if cannabinoids do not also enhance adverse effects of opioids, including those related to abuse. In rhesus monkeys, cannabinoids fail to enhance and often decrease self-administration of the mu opioid receptor agonist ...


Involvement of the CB cannabinoid receptor in cell growth inhibition and G0/G1 cell cycle arrest via the cannabinoid agonist WIN 55,212-2 in renal cell carcinoma.

The anti-tumor properties of cannabinoids have been investigated in many in vitro and in vivo studies. Many of these anti-tumor effects are mediated via cannabinoid receptor types 1 and 2 (CB and CB), comprising the endocannabinoid system (ECS). In this study, we investigated the ECS based on CB and CB receptor gene and protein expression in renal cell carcinoma (RCC) cell lines. In view of their further use for potential treatments, we thus investigated the roles of CB and CB receptors in the anti-prolif...

Cannabinoids in health and disease: pharmacological potential in metabolic syndrome and neuroinflammation.

The use of different natural and/or synthetic preparations of Cannabis sativa is associated with therapeutic strategies for many diseases. Indeed, thanks to the widespread diffusion of the cannabinoidergic system in the brain and in the peripheral districts, its stimulation, or inhibition, regulates many pathophysiological phenomena. In particular, central activation of the cannabinoidergic system modulates the limbic and mesolimbic response which leads to food craving. Moreover, cannabinoid agonists are ab...


Pharmacokinetics of the cannabinoid receptor ligand 18 FMK-9470 in the rat brain - evaluation of models using microPET.

The positron emission tomography ligand [18 F]MK-9470 is an inverse agonist that binds reversibly and with high affinity to the cannabinoid type 1 receptor. Due to its slow brain kinetics, care is required in the definition of its dissociation rates from the receptor. The goal of this study was to investigate pharmacokinetic analysis methods using an arterial input function.

The Inhibitory Effects of Cobalt Protoporphyrin IX and Cannabinoid 2 Receptor Agonists in Type 2 Diabetic Mice.

The activation of the transcription factor Nrf2 inhibits neuropathy and modulates the activity of delta-opioid receptors (DOR) in type 2 diabetic mice but the impact of Nrf2/HO-1 pathway on the antinociceptive actions of cannabinoid 2 receptors (CB2R) has not been assessed. Using male mice BKS.Cg-m+/+Leprdb/J (db/db) we investigated if treatment with cobalt protoporphyrin IX (CoPP), an HO-1 inductor, inhibited mechanical allodynia, hyperglycemia and obesity associated to type 2 diabetes. The antinociceptive...

Single and combined effects of plant-derived (THC, CBD) and synthetic (WIN-55,212) cannabinoids on cognition and cannabinoid-associated withdrawal signs in mice.

It has been suggested that the non-euphorogenic phytocannabinoid cannabidiol (CBD) can ameliorate adverse effects of delta-9-tetrahydrocannabinol (THC). We determined whether CBD ameliorates cognitive deficits and withdrawal signs induced by cannabinoid CB1/CB2 receptor agonists or produces these pharmacological effects on its own.

Synthesis of Photoswitchable Δ(9)-Tetrahydrocannabinol Derivatives Enables Optical Control of Cannabinoid Receptor 1 Signaling.

The cannabinoid receptor 1 (CB1) is an inhibitory G protein-coupled receptor abundantly expressed in the central nerv-ous system. It has rich pharmacology and largely accounts for the recreational use of cannabis. We describe efficient asymmetric syntheses of four photoswitchable Δ(9)-tetrahydrocannabinol derivatives (azo-THCs) from a central building block 3-Br-THC. Using electrophysiology and a FRET-based cAMP assay, two compounds are identified as potent CB1 agonists that change their effect upon illumi...

Incretins: Beyond type 2 diabetes.

While the use of incretins, including GLP-1 receptor agonists and PDD-IV inhibitors, is well established in the treatment of type 2 diabetes, many other aspects of these agents are yet to be discovered and utilized for their potential clinical benefit. These include the potential role of GLP-1 receptor agonists in the induction of weight loss, blood pressure reduction, anti-inflammatory and nephro- and cardio-protective actions. Their potential benefit in type 1 diabetes is also being investigated. This rev...

Cannabinoid receptor types 1 and 2 and peroxisome proliferator-activated receptor-α: distribution in the skin of clinically healthy cats and cats with hypersensitivity dermatitis.

Cannabinoid receptors and peroxisome proliferator-activated receptor-alpha (PPAR-α) are gaining recognition as potential therapeutic targets for the treatment of skin disorders.

Selectivity profiling of NOP, MOP, DOP and KOP receptor antagonists in the rat spinal nerve ligation model of mononeuropathic pain.

Agonists selectively acting at NOP, MOP, DOP and KOP receptors as well as mixed opioid receptor agonists are known to exert anti-hypersensitive efficacy in the rat spinal nerve ligation (SNL) model of neuropathic pain. To investigate the relative contribution of individual opioid receptor activation to the overall efficacy of mixed opioid receptor agonists, selective doses of respective opioid receptor antagonists have to be employed. In order to identify such selective antagonist doses, doses of the select...

Antiparkinsonian and antidyskinetic profiles of two novel potent and selective nociceptin/orphanin FQ receptor agonists.

We previously showed that Nociceptin/orphanin FQ opioid peptide (NOP) receptor agonists attenuate the expression of levodopa-induced dyskinesia in animal models of Parkinson's disease. We now investigate the efficacy of two novel, potent and chemically distinct NOP receptor agonists, AT-390 and AT-403, to improve parkinsonian disabilities and attenuate dyskinesia development and expression.

Clinical Efficacy of Once-weekly Glucagonlike Peptide-1 Receptor Agonists in Patients with Type 2 Diabetes.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are indicated for restoring normoglycemia in patients with type 2 diabetes (T2D). This review analyzed and compared the efficacy results from 30 trials with the once-weekly (OW) GLP-1 RAs albiglutide, dulaglutide, exenatide extended-release (ER) and semaglutide. The 4 OW GLP-1 RAs showed a higher reduction in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG) and body weight, when compared to placebo. Semaglutide significantly reduced the HbA1c le...

Health state utilities associated with attributes of weekly injection devices for treatment of type 2 diabetes.

Glucagon-like peptide-1 (GLP-1) receptor agonists are often recommended as part of combination therapy for type 2 diabetes when oral medication does not result in sufficient glycemic control. Several GLP-1 receptor agonists are available as weekly injections. These medications vary in their injection delivery systems, and these differences could impact quality of life and treatment preference. The purpose of this study was to estimate utilities associated with attributes of injection delivery systems for we...

FFMPEP-d PET imaging shows age- and genotype-dependent impairments in the availability of cannabinoid receptor 1 in a mouse model of Alzheimer's disease.

Contradictory findings on the role of the type 1 cannabinoid receptor (CBR) during the pathogenesis of Alzheimer's disease (AD) have been reported. Here, we evaluated the CBR brain profile in an AD mouse model using longitudinal positron emission tomography with an inverse agonist for CBR, [F]FMPEP-d. APP/PS1-21 and wild-type (n = 8 in each group) mice were repeatedly imaged between 6 to 15 months of age, accompanied by brain autoradiography, western blot, and CBR immunohistochemistry with additional mice...

Discovery of Selective Cannabinoid CB2 Receptor Agonists by High-Throughput Screening.

The endocannabinoid system (ECS) plays a diverse role in human physiology ranging from the regulation of mood and appetite to immune modulation and the response to pain. Drug development that targets the cannabinoid receptors (CB1 and CB2) has been explored; however, success in the clinic has been limited by the psychoactive side effects associated with modulation of the neuronally expressed CB1 that are enriched in the CNS. CB2, however, are expressed in peripheral tissues, primarily in immune cells, and t...

Targeting the Incretin/Glucagon System with Triagonists to Treat Diabetes.

Glucagon-like peptide-1 (GLP-1) receptor agonists have been efficacious for the treatment of type 2 diabetes due to their ability to reduce weight and attenuate hyperglycemia. However, the activity of GLP-1R-directed strategies is sub-maximal, and the only potent, sustainable treatment for metabolic dysfunction is bariatric surgery, necessitating the development of novel therapeutics. GLP-1 is structurally related to glucagon and glucose-dependent insulinotropic peptide (GIP), allowing for the development o...

Cannabinoid receptor 2: a potential novel therapeutic target for sepsis?

Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. It is the most common cause of death among critically ill patients in non-coronary intensive care units and the incidence continues to rise. Although advanced management was applied, the prognosis of sepsis patients remains poor. As a G-protein coupled receptor, cannabinoid receptor 2 (CB2R) was implicated in a wide variety of diseases. In this study, we aimed to investigate the role of CB2R in sepsis.

Ca2+-dependent potassium channels and cannabinoid signaling in the endothelium of apolipoprotein E knockout mice before plaque formation.

Endothelial Ca2+-dependent K+ channels (KCa) regulate endothelial function. We also know that stimulation of type 2 cannabinoid (CB2) receptors ameliorates atherosclerosis. However, whether atherosclerosis is accompanied by altered endothelial KCa- and CB2 receptor-dependent signaling is unknown. By utilizing an in situ patch-clamp approach, we directly evaluated the KCa channel function and the CB2 receptor-dependent electrical responses in the endothelium of aortic strips from young ApoE-/- and C57Bl/6 mi...

Evaluation of different drug classes on transient sciatic nerve injury-depressed marble burying in mice.

A great need exists for the identification of new effective analgesics to treat sustained pain. However, most preclinical nociceptive assays measure behavioral responses evoked by noxious stimuli (i.e., pain-stimulated behavior), which presents a challenge to distinguish between motor impairing and antinociceptive effects of drugs. Here, we demonstrate that chronic constriction injury of the sciatic nerve (CCI) elicits common pain-stimulated responses (i.e., mechanical allodynia and thermal hyperalgesia) as...

Efficacy of glucagon-like peptide-1 receptor agonists compared to dipeptidyl peptidase-4 inhibitors for the management of type 2 diabetes: A meta-analysis of randomized clinical trials.

Glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors are both incretin-based therapies for type 2 diabetes (T2DM) but have distinct efficacy and side effect profiles. We thus performed a systematic review and meta-analysis to compare the effects of GLP-1 agonists to DPP-4 inhibitors on glycaemic control, weight and incidence of adverse events in adults with T2DM. We also sought to determine whether there was any additional effect in switching from DPP-4 inhibitor to GLP-1 a...

Effects of Cocaine Self-Administration and Its Extinction on the Rat Brain Cannabinoid CB1 and CB2 Receptors.

The aim of this study was to evaluate changes in the expression of cannabinoid type 1 (CB1) and 2 (CB2) receptor proteins in several brain regions in rats undergoing cocaine self-administration and extinction training. We used a triad-yoked procedure to distinguish between the motivational and pharmacological effects of cocaine. Using immunohistochemistry, we observed a significant decrease in CB1 receptor expression in the prefrontal cortex, dorsal striatum, and the basolateral and basomedial amygdala foll...

Pharmacologic Characterization of Omidenepag Isopropyl, a Novel Selective EP2 Receptor Agonist, as an Ocular Hypotensive Agent.

The objective of this study was to investigate the pharmacologic characteristics of omidenepag isopropyl (OMDI), a compound developed as a novel intraocular pressure (IOP)-lowering agent, with better IOP control and fewer side effects than other prostanoid receptor agonists such as prostaglandin F receptor (FP) agonists.

Early Alteration of Distribution and Activity of Hippocampal Type-1 Cannabinoid Receptor in Alzheimer's Disease-like Mice Overexpressing the Human Mutant Amyloid Precursor Protein.

Besides its involvement in Alzheimer's disease (AD) as precursor of the neurotoxic amyloid peptides, the pathophysiological impact of brain accumulation of amyloid precursor protein (APP) is not yet well understood. Recent studies reported that APP interacts with other membrane proteins, including G protein coupled receptors, affecting their biological functions. Here, we focused on the study of the potential impact of human mutant APP on expression, distribution and activity of type-1 cannabinoid (CB) rece...

Glucagon-Like Peptide-1 Receptor Agonists for the Treatment of Type 2 Diabetes Mellitus: A Position Statement of the Korean Diabetes Association.

The glucagon-like peptide-1 receptor agonists (GLP-1RAs) were recommended as a monotherapy or combination therapy with oral hypoglycemic agents or basal insulin in the position statement of the Korean Diabetes Association 2017 for pharmacological therapy. Many randomized clinical trials and systematic reviews report that GLP-1RAs have considerable glucose-lowering effect and lead to weight reduction and low risk of hypoglycemia when used as a monotherapy or combination therapy. The cardiovascular safety of ...

The tamoxifen derivative ridaifen-B is a high affinity selective CB receptor inverse agonist exhibiting anti-inflammatory and anti-osteoclastogenic effects.

Selective estrogen receptor modulators (SERMs) target estrogen receptors (ERs) to treat breast cancer and osteoporosis. Several SERMs exhibit anti-cancer activity not related to ERs. To discover novel anti-cancer drugs acting via ER-independent mechanisms, derivatives of the SERM tamoxifen, known as the "ridaifen" compounds, have been developed that exhibit reduced or no ER affinity, while maintaining cytotoxicity. Tamoxifen and other SERMs bind to cannabinoid receptors with moderate affinity. Therefore, ER...
