Characterization of Lignanamides from Hemp (Cannabis sativa L. ) Seed and their Antioxidant and Acetylcholinesterase Inhibitory Activities.

Image result for J Agric Food Chem.

“Hempseed is known for its content in fatty acids, proteins and fiber, which contribute to its nutritional value.

Here we studied the secondary metabolites of hempseed aiming at identifying bioactive compounds that could contribute to its health benefits.

This investigation led to the isolation of four new lignanamides cannabisin M, 2, cannabisin N, 5, cannabisin O, 8 and 3,3′-demethyl-heliotropamide, 10, together with ten known lignanamides, among which 4 was identified for the first time from hempseed.

Structures were established on the basis of NMR, HR-MS, UV, IR as well as by comparison with the literature data.

Lignanamides 2, 7, 9-14 showed good antioxidant activity among which 7, 10 and 13 also inhibited acetylcholinesterase in vitro.

The new identified compounds in this study added to the diversity of hempseed composition and the bioassays implied that hempseed, with lignanamides as nutrients, may be a good source of bioactive and protective compounds.”  http://www.ncbi.nlm.nih.gov/pubmed/26585089

“Alzheimer’s Disease (AD) is the most common single cause of dementia in our ageing society. On full assessment and diagnosis of AD, initiation of an AChe inhibitor is recommended as early as possible, it is important that AChe inhibitor therapy is considered for patients with mild to moderate AD.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2014378/

 “The Effects of Hempseed Meal Intake and Linoleic Acid on Drosophila Models of Neurodegenerative Diseases and Hypercholesterolemia. Our results indicate that hempseed meal (HSM) and linoleic acid are potential candidates for the treatment of Alzheimer’s disease (AD) and cardiovascular disease. These results show that HSM may prove of great utility as a health food, with potential for the prevention of AD and cardiovascular disease.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3933972/

Anti-Obesity Effect of the CB2 Receptor Agonist JWH-015 in Diet-Induced Obese Mice.

“The cannabinoid receptor 2 (CB2) is well known for its immune modulatory role. However, recent localisation of CB2 receptors in metabolically active tissue suggests that the CB2 receptor plays a significant role in energy homeostasis.

This study was designed to investigate the impact of chronic CB2 receptor stimulation on food intake, body weight and mood.

These results demonstrate a role for CB2 receptors in modulating energy homeostasis and obesity associated metabolic pathologies in the absence of any adverse impact on mood.”

Controlled release tablet formulation containing natural δ9 tetrahydrocannabinol.

“Cannabinoids are increasingly being used in the treatment of chemotherapy induced nausea and vomiting (CINV) because of their action on the cannabinoid receptors, CB1 and CB2.

The currently marketed capsule formulations (sesame oil based and crystalline powder) are required to be administered frequently to maintain therapeutic levels, which leads to non-compliance.

In the present study, oral controlled release tablet formulations of Δ9- tetrahydrocannabinol (THC) were prepared using the lipids Precirol® and Compritrol®. Release profiles using THC-lipid matrices and/or with the lipids in the external phase (blend) were evaluated…

The overall results demonstrate the feasibility of preparing oral THC tablets for once a day administration which can improve CINV management.”

Cannabinoids in the management of chronic pain: a front line clinical perspective.

“Chronic pain is an escalating public health problem. Currently available treatments are inadequate to control chronic pain conditions, and there is a critical need for novel treatments.

Over a half century of elegant preclinical research has identified the presence of a sophisticated endocannabinoid system that is part of our natural pain and immune defense network.

Convergent work has supported the significant potential to exploit this system to decrease pain and inflammation.

Although the clinical research remains in its infancy, recent systematic reviews have found that 25 of 30 randomized controlled trials have demonstrated a significant analgesic effect.

The authors concluded that cannabinoids currently available for clinical use demonstrate a modest analgesic effect and are safe for the management of chronic pain.

There is a critical need for more translational research so that the excellent work of Dr. Itai Bab and our basic science colleagues around the world can move forward in providing novel cannabinoid-based medicines.

This should include more potent analgesics that are limited in side effects with several routes of delivery. Our patients deserve additional agents for pain control with a novel mechanism of action, and cannabinoids are the new frontier.”

Pharmacological benefits of selective modulation of cannabinoid receptor type 2 (CB2) in experimental Alzheimer’s disease.

“Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that pervasively affects the population across the world.

Currently, there is no effective treatment available for this and existing drugs merely slow the progression of cognitive function decline. Thus, massive effort is required to find an intended therapeutic target to overcome this condition.

The present study has been framed to investigate the ameliorative role of selective modulator of cannabinoid receptor type 2 (CB2), 1-phenylisatin in experimental AD condition…

Hence, this study concludes that CB2 receptor modulation can be a potential therapeutic target for the management of AD.”

The effect of five day dosing with THCV on THC-induced cognitive, psychological and physiological effects in healthy male human volunteers: A placebo-controlled, double-blind, crossover pilot trial.

“Cannabis is mostly grown under illegal and unregulated circumstances, which seems to favour a product increasingly high in its main cannabinoid ∆-9-tetrahydrocannabinol (THC). ∆-9-tetrahydrocannabivarin (THCV) is a relatively untested cannabinoid which is said to be a cannabinoid receptor neutral antagonist, and may inhibit the effects of THC.

In this first study of THC and THCV, THCV inhibited some of the well-known effects of THC, while potentiating others.”

The cannabinoid system in the retrosplenial cortex modulates fear memory consolidation, reconsolidation, and extinction.

“Despite the fact that the cannabinoid receptor type 1 (CB1R) plays a pivotal role in emotional memory processing in different regions of the brain, its function in the retrosplenial cortex (RSC) remains unknown. Here, using contextual fear conditioning in rats, we showed that a post-training intra-RSC infusion of the CB1R antagonist AM251 impaired, and the agonist CP55940 improved, long-term memory consolidation. Additionally, a post-reactivation infusion of AM251 enhanced memory reconsolidation, while CP55940 had the opposite effect. Finally, AM251 blocked extinction, whereas CP55940 facilitated it and maintained memory extinguished over time. Altogether, our data strongly suggest that the cannabinoid system of the RSC modulates emotional memory.”

Cannabidiol as potential treatment in refractory pediatric epilepsy.

“In recent years there has been great scientific and public interest focused on the therapeutic potential of compounds derived from cannabis for the treatment of refractory epilepsy in children.

From in vitro and in vivo studies on animal models, cannabidiol (CBD) appears to be a promising anticonvulsant drug with a favorable side-effect profile.

In humans, CBD efficacy and safety is not supported by well designed trials and its use has been described by anecdotal reports.

It will be necessary to investigate CBD safety, pharmacokinetics and interaction with other antiepileptic drugs alongside performing double-blinded placebo-controlled trials in order to obtain conclusive data on its efficacy and safety in children.”

Cannabis Use Can Improve Effectiveness of Hepatitis C Therapy

Home

“Recent research by Diana L. Sylvestre, MD, assistant clinical professor in the Department of Medicine at the University of California, San Francisco, and colleagues suggests that the use of cannabis during hepatitis C virus (HCV) treatment may offer symptomatic and virological benefit to some patients by helping them maintain adherence to the challenging and often painful medication regimen.”
