Endocannabinoid Levels in Ulcerative Colitis Patients Correlate With Clinical Parameters and Are Affected by Cannabis Consumption

Posted on September 24, 2021 by David

“Inflammatory bowel diseases (IBDs) are chronic, idiopathic, inflammatory, gastrointestinal disorders.

The endocannabinoid system may have a role in the pathogenesis of IBD.

We aimed to assess whether cannabis treatment influences endocannabinoids (eCBs) level and clinical symptoms of IBD patients.

Conclusion

Our study supports the notion that cannabis use affects eCB “tone” in UC patients and may have beneficial effects on disease symptoms in UC patients.”

A Review of the Potential Use of Pinene and Linalool as Terpene-Based Medicines for Brain Health: Discovering Novel Therapeutics in the Flavours and Fragrances of Cannabis

Posted on September 16, 2021 by David

“”Medicinal cannabis” is defined as the use of cannabis-based products for the treatment of an illness. Investigations of cannabis compounds in psychiatric and neurological illnesses primarily focus on the major cannabinoids, cannabidiol (CBD) and Δ⁹-tetrahydrocannabinol (Δ⁹-THC), which are hypothesised to benefit multiple illnesses manifesting cognitive impairment, neurodegeneration and neuro-inflammation, as well as chronic pain, epilepsy and post-traumatic stress disorder, respectively.

The cannabis plant contains >500 compounds, including terpenes responsible for the flavour and fragrance profiles of plants. Recently, research has begun providing evidence on the potential use of certain plant-derived terpenes in modern medicine, demonstrating anti-oxidant, anti-inflammatory, and neuroprotective effects of these compounds.

This review examined the effects of two key terpenes, pinene and linalool, on parameters relevant to neurological and psychiatric disorders, highlighting gaps in the literature and recommendations for future research into terpene therapeutics.

Overall, evidence is mostly limited to preclinical studies and well-designed clinical trials are lacking. Nevertheless, existing data suggests that pinene and linalool are relevant candidates for further investigation as novel medicines for illnesses, including stroke, ischemia, inflammatory and neuropathic pain (including migraine), cognitive impairment (relevant to Alzheimer’s disease and ageing), insomnia, anxiety, and depression.

Linalool and pinene influence multiple neurotransmitter, inflammatory and neurotrophic signals as well as behaviour, demonstrating psycho-activity (albeit non-intoxicating). Optimising the phytochemical profile of cannabis chemovars to yield therapeutic levels of beneficial terpenes and cannabinoids, such as linalool, pinene and CBD, could present a unique opportunity to discover novel medicines to treat psychiatric and neurological illnesses; however, further research is needed.”

“Overall, it appears that the importance of the terpene profile of plants to humans extends further than mere olfactory and gustatory delight. Rather, these compounds have the potential for use as treatments for serious chronic neurological and psychiatric illnesses.”

Cannabidiol Effectively Promoted Cell Death in Bladder Cancer and the Improved Intravesical Adhesion Drugs Delivery Strategy Could Be Better Used for Treatment

Posted on September 14, 2021 by David

“Cannabidiol (CBD), a primary bioactive phytocannabinoid extracted from hemp, is reported to possess potent anti-tumorigenic activity in multiple cancers.

However, the effects of CBD on bladder cancer (BC) and the underlying molecular mechanisms are rarely reported.

Here, several experiments proved that CBD promoted BC cells (T24, 5637, and UM-UC-3) death.

In summary, this work demonstrates that CBD may become a novel reliable anticancer drug and the developed intravesical adhesion system is expected to turn into a potential means of BC chemotherapy drug delivery.

We believe that our study makes a significant contribution to the field because these results can be developed as a promising strategy for a safer and more efficient anticancer therapy.”

Cannabinoids for the treatment of refractory neuropathic pruritus in amyotrophic lateral sclerosis: A case report

Posted on September 13, 2021 by David

“Background: Neuropathic symptoms have a wide variety of manifestations, ranging from pain to pruritus. Neuropathic pruritus is a type of chronic pruritus related to damaged small fibers. Cannabinoids have evidence to manage neuropathic symptoms. We present a case of refractory neuropathic pruritus that was successfully managed with the use of oral cannabinoids.

Case presentation: A 60-year-old male with amyotrophic lateral sclerosis with ongoing pruritus despite the use of standard neuropathic therapies.

Formulation of a plan: A balanced oral cannabinoid from a licensed producer was preferred as it has evidence for neuropathic symptoms and is generally well tolerated.

Outcome: The patient showed improvement to his pruritus score from 7/10 to 3/10. There was initial increased sedation but tolerance developed quickly.

Lessons learned from case: Cannabinoids are possibly safe and effective in management of neuropathic pruritus.”

https://pubmed.ncbi.nlm.nih.gov/34510973/

“Neuropathic pruritus is a chronic form of pruritus that causes significant symptom burden and can be difficult to treat. Cannabinoids have evidence to manage chronic neuropathic pain. This case demonstrates the safe and effective use of cannabinoids to manage neuropathic pruritus.”

Cannabinoids and Cancer

Posted on September 11, 2021 by David

“Cannabinoids, active components of the plant Cannabis sativa, had been used for centuries in ancient medicine as therapeutic remedies for a variety of conditions, before becoming stigmatized due to their psychoactive effects.

In the second half of the 19th century, phyto-cannabinoids have been re-evaluated after the discovery of the chemical structure and isolation of different substances, and the subsequent development of cannabinoid-based drugs that have been FDA approved mainly to treat chemotherapy-induced nausea, insomnia and appetite, epilepsy, spasticity, and pain management.

Then, the elucidation of the endocannabinoid system, from the initial type 1 and type 2 (CB₁ and CB₂) cannabinoid receptors and their endogenous ligands (especially N-arachidonoylethanolamine, or anandamide, and 2-arachidonoylglycerol) to the emerging complexity of a wider system made up of additional putative receptors, ligands and enzymes, altogether termed endocannabinoidome, has further boosted research into the therapeutic potential of phyto-, endo- and even syntho-(synthetic) cannabinoids, cancer treatment included.”

Cannabinoids and Endocannabinoid System Changes in Intestinal Inflammation and Colorectal Cancer

Posted on September 11, 2021 by David

“Despite the multiple preventive measures and treatment options, colorectal cancer holds a significant place in the world’s disease and mortality rates. The development of novel therapy is in critical need, and based on recent experimental data, cannabinoids could become excellent candidates. This review covered known experimental studies regarding the effects of cannabinoids on intestinal inflammation and colorectal cancer. In our opinion, because colorectal cancer is a heterogeneous disease with different genomic landscapes, the choice of cannabinoids for tumor prevention and treatment depends on the type of the disease, its etiology, driver mutations, and the expression levels of cannabinoid receptors. In this review, we describe the molecular changes of the endocannabinoid system in the pathologies of the large intestine, focusing on inflammation and cancer.”

https://pubmed.ncbi.nlm.nih.gov/34503163/

“In recent years, multiple preclinical studies have shown that changes in endocannabinoid system signaling may have various effects on intestinal inflammation and colorectal cancer. However, not all tumors can respond to cannabinoid therapy in the same manner. Given that colorectal cancer is a heterogeneous disease with different genomic landscapes, experiments with cannabinoids should involve different molecular subtypes, emerging mutations, and various stages of the disease. We hope that this review can help researchers form a comprehensive understanding of cannabinoid interactions in colorectal cancer and intestinal bowel diseases. We believe that selecting a particular experimental model based on the disease’s genetic landscape is a crucial step in the drug discovery, which eventually may tremendously benefit patient’s treatment outcomes and bring us one step closer to individualized medicine.”

The antitumor activity of cannabidiol on lung cancer cell lines A549 and H1299: the role of apoptosis

Posted on September 10, 2021 by David

Publication Cover “In the recent years, the application of new antitumor drugs has focused on the replacement of conventional chemotherapeutics with compounds derived from natural products.

Cannabidiol (CBD) is one of the 113 cannabinoids derived from the plant Cannabis sativa and is characterized with complex and not entirely understood biological function. Unlike the other most abundant cannabinoid in Cannabis sativa – tetrahydrocannabinol, cannabidiol has low affinity to the endocannabinoid receptors and the manifestation of its activity does not appear to rely on the endocannabinoid system.

Cannabidiol is used in the treatment of many diseases including some types of cancer.

The aim of our study was to evaluate the cytotoxic activity of cannabidiol and its effect on the process of programmed cell death. This process is directly involved in the antitumor effect of many drugs.

We found that CBD treatment led to a dose-dependant apoptosis increase in p53 positive A549 cells.

Several studies have demonstrated that cannabinoids also have antineoplastic effect and are usually accompanied with no negative side effects such as the ones produced by the conventional chemotherapy treatment.”

The Endocannabinoid System: A Potential Target for the Treatment of Various Diseases

Posted on September 10, 2021 by David

“The Endocannabinoid System (ECS) is primarily responsible for maintaining homeostasis, a balance in internal environment (temperature, mood, and immune system) and energy input and output in living, biological systems.

In addition to regulating physiological processes, the ECS directly influences anxiety, feeding behaviour/appetite, emotional behaviour, depression, nervous functions, neurogenesis, neuroprotection, reward, cognition, learning, memory, pain sensation, fertility, pregnancy, and pre-and post-natal development.

The ECS is also involved in several pathophysiological diseases such as cancer, cardiovascular diseases, and neurodegenerative diseases. In recent years, genetic and pharmacological manipulation of the ECS has gained significant interest in medicine, research, and drug discovery and development.

The distribution of the components of the ECS system throughout the body, and the physiological/pathophysiological role of the ECS-signalling pathways in many diseases, all offer promising opportunities for the development of novel cannabinergic, cannabimimetic, and cannabinoid-based therapeutic drugs that genetically or pharmacologically modulate the ECS via inhibition of metabolic pathways and/or agonism or antagonism of the receptors of the ECS. This modulation results in the differential expression/activity of the components of the ECS that may be beneficial in the treatment of a number of diseases.

This manuscript in-depth review will investigate the potential of the ECS in the treatment of various diseases, and to put forth the suggestion that many of these secondary metabolites of Cannabis sativa L. (hereafter referred to as “C. sativa L.” or “medical cannabis”), may also have potential as lead compounds in the development of cannabinoid-based pharmaceuticals for a variety of diseases.”
