“Patients with spinal cord injury (SCI) undergo severe loss of bone mineral below the level of lesion, and data on available treatment options after SCI is scarce. The aim of this work was to investigate the therapeutic effect of cannabidiol (CBD), a non-psychoactive cannabis, on sublesional bone loss in a rat model of SCI. In conclusion, CBD administration attenuated SCI-induced sublesional cancellous bone loss.” https://www.ncbi.nlm.nih.gov/pubmed/28479140 http://www.sciencedirect.com/science/article/pii/S0014299917303230]]>

Comparative in silico analyses of Cannabis sativa, Prunella vulgaris and Withania somnifera compounds elucidating the medicinal properties against rheumatoid arthritis
“From last decade, there has been progressive improvement in computational drug designing. Several diseases are being cured from different plant extracts and products.
Rheumatoid arthritis (RA) is the most shared disease among auto-inflammatory diseases. Tumor necrosis factor (TNF)-α is associated with RA pathway and has adverse effects. Extensive literature review showed that plant species under study (Cannabis sativa, Prunella vulgaris and Withania somnifera) possess anti-inflammatory, anti-arthritic and anti-rheumatic properties. 13 anti-inflammatory compounds were characterized and filtered out from medicinal plant species and analyzed for RA by targeting TNF-α through in silicoanalyses. By using ligand based pharmacophore generation approach and virtual screening against natural products libraries we retrieved twenty unique molecules that displayed utmost binding affinity, least binding energies and effective drug properties. The docking analyses revealed that Ala-22, Glu-23, Ser-65, Gln-67, Tyr-141, Leu-142, Asp-143, Phe-144 and Ala-145 were critical interacting residues for receptor-ligand interactions. It is proposed that the RA patients should use reported compounds for the prescription of RA by targeting TNF-α. This report is opening new dimensions for designing innovative therapeutic targets to cure RA.”Combined cannabinoid therapy via an oromucosal spray.
“Extensive basic science research has identified the potential therapeutic benefits of active compounds extracted from the Cannabis sativa L. plant (the cannabinoids). It is recognized that a significant proportion of patients suffering with the debilitating symptoms of pain and spasticity in multiple sclerosis or other conditions smoke cannabis despite the legal implications and stigma associated with this controlled substance. GW Pharmaceuticals have developed Sativex (GW- 1000-02), a combined cannabinoid medicine that delivers and maintains therapeutic levels of two principal cannabinoids, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), via an oromucosal pump spray, that aims to minimize psychotropic side effects.” https://www.ncbi.nlm.nih.gov/pubmed/16969427 “Sativex has proved to be well tolerated and successfully self-administered and self-titrated in both healthy volunteers and patient cohorts. Clinical assessment of this combined cannabinoid medicine has demonstrated efficacy in patients with intractable pain (chronic neuropathic pain, pain due to brachial plexus nerve injury, allodynic peripheral neuropathic pain and advanced cancer pain), rheumatoid arthritis and multiple sclerosis (bladder problems, spasticity and central pain), with no significant intoxication-like symptoms, tolerance or withdrawal syndrome.” https://journals.prous.com/journals/servlet/xmlxsl/pk_journals.xml_summaryn_pr?p_JournalId=4&p_RefId=1021517 “Sativex(®) (nabiximols, USAN name) oromucosal spray contains the two main active constituents of Cannabis sativa, tetrahydrocannabinol and cannabidiol in a 1:1 molecular ratio, and acts as an endocannabinoid system modulator.” https://www.ncbi.nlm.nih.gov/pubmed/21449855
“Abuse potential and psychoactive effects of δ-9-tetrahydrocannabinol and cannabidiol oromucosal spray (Sativex), a new cannabinoid medicine. Evidence to date suggests that abuse or dependence on Sativex is likely to occur in only a very small proportion of recipients.” https://www.ncbi.nlm.nih.gov/pubmed/21542664
]]>GPR55 and the regulation of glucose homeostasis.
“Pathophysiological conditions such as obesity and type 2 diabetes (T2D) are reportedly associated to over-activation of the endocannabinoid system (ECS). Therefore, modulation of the ECS offers potential therapeutic benefits on those diseases. GPR55, the receptor for L-α-lysophosphatidylinositol (LPI) that has also affinity for various cannabinoid ligands, is distributed at the central and peripheral level and it is involved in several physiological processes. This review summarizes the localization and role of GPR55 in tissues that are crucial for the regulation of glucose metabolism, and provides an update on its contribution in obesity and insulin resistance. The therapeutic potential of targeting the GPR55 receptor is also discussed.” https://www.ncbi.nlm.nih.gov/pubmed/28457969]]>
The Role of Cannabinoids in the Treatment of Cancer in Pediatric Patients.
“Cannabis has been used in folk medicine to alleviate pain, depression, amenorrhea, inflammation and numerous other medical conditions. In cancer patients specifically, cannabinoids are well known to exert palliative effects; their best-established use is the inhibition of chemotherapy-induced nausea and vomiting, but they are applied also to alleviate pain, stimulate appetite, and attenuate wasting. More recently, cannabinoids have gained special attention for their role in cancer cell proliferation and death. Anti-cancer efficacy of cannabinoids: The ability of cannabinoids to reduce tumor growth was reported for the first time by Munson et al. in 1975. They showed by in vitro and in vivo experiments that several phytocannabinoids, including THC, decreased Lewis lung adenocarcinoma proliferation in a dose-dependent manner. Nevertheless, it was not until the 2000s that the interest in these compounds as anti-cancer agents was renewed, predominantly due to the work of Guzman in gliomas, and the demonstration of cannabinoids’ anti-cancer effects on various types of tumors. The anti-tumorigenic effect of the endo- and phytocannabinoids was demonstrated in several in vitro and in vivo models of a wide variety of adult tumors including glioma, prostate, breast, leukemia, lymphoma, pancreas, melanoma, thyroid, colorectal and hepatocellular carcinoma tumors. Given our positive results, we suggest that non-THC cannabinoids such as CBD might provide a basis for the development of novel therapeutic strategies without the typical psychotropic effects of THC that limit its use in pediatric patients. Overall, the cannabinoids, and specifically the non-psychoactive CBD, may show future promise in the treatment of cancer” https://www.ima.org.il/FilesUpload/IMAJ/0/228/114216.pdf https://www.ima.org.il/imaj/ViewArticle.aspx?aId=4044 https://www.ncbi.nlm.nih.gov/pubmed/28457057]]>
Marijuana compounds show promise in treatment of cardiac disease
“A Nevada company is hoping to develop new medicines for heart failure using compounds in marijuana and a novel therapy identified by a University of Hawaiʻi at Mānoa researcher. Dr. Alexander Stokes, assistant research professor in the Department of Cell and Molecular Biology at the UH John A. Burns School of Medicine, obtained a U.S. patent for his novel therapy in 2015. The patent claims the cannabinoid receptor TRPV1 can be regulated therapeutically by plant-based cannabinoids.” https://medicalxpress.com/news/2017-01-marijuana-compounds-treatment-cardiac-disease.html

“The cannabinoid CB2 receptor (CB2R) represents a promising therapeutic target for various forms of tissue injury and inflammatory diseases. There is a great interest in the development of selective type-2 cannabinoid receptor (CB2R) agonists as potential drug candidates for various pathophysiological conditions, which include chronic and inflammatory pain, pruritus, diabetic neuropathy and nephropathy, liver cirrhosis, and protective effects after ischaemic-reperfusion injury.” https://www.nature.com/articles/ncomms13958
