Cannabinoid compounds in South African Cannabis sativa L.

Posted on May 23, 2015 by David

“Dagga (Cannabis sativa L.) samples were collected from various geographical regions of South Africa. These were classified into age, sex and plant part and the cannabinoids were analysed quantitatively by gas-liquid chromatography and mass spectrometry. Analytical results show that there appears to be at least three chemovariants of Cannabis sativa growing in South Africa with respect to relative cannabinoid content. One of these variants appears to be unique to Southern Africa. It also appears that South African C. sativa ranks among the world’s more potent C. sativa variants in terms of its delta 9-tetrahydrocannabinol content.”

Impact of cannabis treatment on the quality of life, weight and clinical disease activity in inflammatory bowel disease patients: a pilot prospective study.

Posted on May 17, 2015 by David

“Inflammatory bowel disease (IBD) patients suffer from significant morbidity and diminished life quality.

The plant cannabis is beneficial in various gastrointestinal diseases, stimulating appetite and causing weight gain.

Our aims were to assess whether treatment with inhaled cannabis improves quality of life, disease activity and promotes weight gain in these patients.

CONCLUSIONS:

Three months’ treatment with inhaled cannabis improves quality of life measurements, disease activity index, and causes weight gain and rise in BMI in long-standing IBD patients.”

The cannabinoid CB₂ receptor-selective phytocannabinoid beta-caryophyllene exerts analgesic effects in mouse models of inflammatory and neuropathic pain.

Posted on May 10, 2015 by David

“The widespread plant volatile beta-caryophyllene (BCP) was recently identified as a natural selective agonist of the peripherally expressedcannabinoid receptor 2 (CB₂).

…the natural plant product BCP may be highly effective in the treatment of long lasting, debilitating pain states. Our results have important implications for the role of dietary factors in the development and modulation of chronic pain conditions.

Cannabis preparations, which have been used since thousands of years for the treatment of pain have recently come again into the focus as potential therapeutics for inflammatory and neuropathic pain conditions. Currently, cannabis extracts and synthetic preparations of the psychoactive cannabis compound Δ9-tetrahydrocannabinol (THC) have been approved in many countries for clinical pain management at doses and formulations that show on only minor central side effects…

A natural selective agonist for CB2 receptors is the plant volatile BCP, which represents a dietary phytocannabinoid. BCP is found in large amounts in the essential oils of many common spices and food plants… Several health effects have been attributed to BCP or medicinal plants containing BCP, including anti-inflammatory, local anesthetic, anti-carcinogenic, anti-fibrotic and anxiolytic-like activity.

In the present study, we investigated the analgesic effects of BCP in formalin-induced inflammation model and in a model of neuropathic pain, which involves the partial ligation of the sciatic nerve… BCP is the first natural CB2 receptor agonist, which could orally reduce inflammatory responses in different animal models of pain.

Thus, it is likely that BCP belongs to a group of common plant natural products with major potential impact on human health.

The oral intake of this dietary cannabinoid with vegetable food could be advantageous in the daily routine clinical practice over synthetic cannabinoid agonists.”

The role of cannabinoids in adult neurogenesis.

Posted on May 9, 2015 by David

“Cannabinoids are a unique class of chemical compounds incorporating plant-derived cannabinoids (the active components of Cannabis sativa), the endogenous cannabinoids and synthetic cannabinoid ligands, and these compounds are becoming increasingly recognized for their roles in neural developmental processes.

Indeed, cannabinoids have clear modulatory roles in adult neurogenesis, likely through activation of both CB1 and CB2receptors.

In recent years a large body of literature has deciphered the signalling networks involved in cannabinoid-mediated regulation of neurogenesis. This timely review summarises the evidence that the cannabinoid system is intricately associated with neuronal differentiation and maturation of NPCs, and highlights intrinsic/extrinsic signalling mechanisms that are cannabinoid targets.

Overall these findings identify the central role of the cannabinoid system in adult neurogenesis in the hippocampus and the lateral ventricles, and hence provide insight into the processes underlying post-developmental neurogenesis in the mammalian brain.”

The relationship between cannabidiol and psychosis: A review.

Posted on May 9, 2015 by David

“Cannabis sativa is the most widely used illicit drug in the world…

THC is considered responsible for the main psychotropic effects of the drug, while CBD seems to antagonize these effects, particularly those that induce psychosis.

The effects of Cannabis seem to depend on several variables related to the type of plant, its strength, usage patterns, and intersubjective variations.

CBD could be used to treat several conditions, including psychosis, when the current treatment is associated with significant side effects.

…further research involving the possible antipsychotic effect and other potential positive effects of Cannabis are needed.”

The Antitumor Activity of Plant-Derived Non-Psychoactive Cannabinoids.

Posted on April 29, 2015 by David

“As a therapeutic agent, most people are familiar with the palliative effects of the primary psychoactive constituent of Cannabis sativa (CS), Δ9-tetrahydrocannabinol (THC), a molecule active at both the cannabinoid 1 (CB1) and cannabinoid 2 (CB2) receptor subtypes.

Through the activation primarily of CB1 receptors in the central nervous system, THC can reduce nausea, emesis and pain in cancer patients undergoing chemotherapy.

During the last decade, however, several studies have now shown that CB1 and CB2 receptor agonists can act as direct antitumor agents in a variety of aggressive cancers.

In addition to THC, there are many other cannabinoids found in CS, and a majority produces little to no psychoactivity due to the inability to activate cannabinoid receptors.

For example, the second most abundant cannabinoid in CS is the non-psychoactive cannabidiol (CBD). Using animal models, CBD has been shown to inhibit the progression of many types of cancer including glioblastoma (GBM), breast, lung, prostate and colon cancer.

This review will center on mechanisms by which CBD, and other plant-derived cannabinoids inefficient at activating cannabinoid receptors, inhibit tumor cell viability, invasion, metastasis, angiogenesis, and the stem-like potential of cancer cells.

We will also discuss the ability of non-psychoactive cannabinoids to induce autophagy and apoptotic-mediated cancer cell death, and enhance the activity of first-line agents commonly used in cancer treatment.”

Alkylindole-sensitive receptors modulate microglial cell migration and proliferation.

Posted on April 29, 2015 by David

“Ligands targeting G protein-coupled receptors (GPCR) expressed by microglia have been shown to regulate distinct components of their activation process, including cell proliferation, migration and differentiation into M1 or M2 phenotypes.

Cannabinoids, including the active component of the Cannabis plant, tetrahydrocannabinol (THC), and the synthetic alkylindole (AI) compound, WIN55212-2 (WIN-2), activate two molecularly identified GPCRs: CB1 and CB2 .

Our results suggest that microglia express functional AI-sensitive receptors that control select components of their activation process.

Agonists of these novel targets might represent a novel class of therapeutics to influence the microglial cell activation process. ”

[The role of endocannabinoid system in physiological and pathological processes in the eye].

Posted on April 28, 2015 by David

“Plant of Cannabis sativa/ marihuana except for its psychotropic effects possesses a range of pharmacological properties, that has been utilized for medical purposes over a period of millenia.

Investigations concerning biochemical mechanism of action of the main and most active pharmacological compound of Cannabis sativa, cannabinoid 9-THC, contributed to the discovery of cannabinoid receptors both in the central nervous system (CNS) and peripheral tissues, that mediated actions of this substance.

The discovery made possible identification of a new, endogenous signaling system referred to as the endocannabinoid system.

Besides cannabinoid receptors CB1 and CB2, the system includes it’s endogenic ligands (endocannabinoids) and compounds that participate in their biosynthesis and inactivation. Structure and functioning of the endocannabinoid system is conservative in all vertebrates.

It’s activation with plant, synthetic and endogenous cannabinoids has an influence on multiple physiological and pathological processes within the eye.”

Therapeutic potential of cannabis in pain medicine†

Posted on April 27, 2015 by David

BJA

“Cannabis has been of medicinal and social significance for millennia.

It is obtained from Cannabis sativa and the plant’s name reflects its ancient use—cannabis may represent a compound of Sanskrit and Hebrew words meaning ‘fragrant cane’, while sativa is Latin for cultivated.

Cannabis is also known as hemp.

Marijuana describes the dried cannabis flowers and leaves which are smoked, while hashish refers to blocks of cannabis resin which can be eaten.

Advances in cannabis research have paralleled developments in opioid pharmacology whereby a psychoactive plant extract has elucidated novel endogenous signalling systems with therapeutic significance.

Cannabinoids (CBs) are chemical compounds derived from cannabis.

This review discusses the basic science and clinical aspects of CB pharmacology with a focus on pain medicine.

Advances in cannabis research have ensured a future for these analgesic molecules which have been used since antiquity.”
