β-Caryophyllene Mitigates Collagen Antibody Induced Arthritis (CAIA) in Mice Through a Cross-Talk between CB2 and PPAR-γ Receptors.

biomolecules-logo “β-caryophyllene (BCP) is a cannabinoid receptor 2 (CB2) agonist that tempers inflammation.

An interaction between the CB2 receptor and peroxisome proliferator-activated receptor gamma (PPAR-γ) has been suggested and PPAR-γ activation exerts anti-arthritic effects.

The aim of this study was to characterize the therapeutic activity of BCP and to investigate PPAR-γ involvement in a collagen antibody induced arthritis (CAIA) experimental model.

BCP significantly hampered the severity of the disease, reduced relevant pro-inflammatory cytokines, and increased the anti-inflammatory cytokine IL-13. BCP also decreased joint expression of matrix metalloproteinases 3 and 9. Arthritic joints showed increased COX2 and NF-ĸB mRNA expression and reduced expression of the PPARγ coactivator-1 alpha, PGC-1α, and PPAR-γ. These conditions were reverted following BCP treatment.

Finally, BCP reduced NF-ĸB activation and increased PGC-1α and PPAR-γ expression in human articular chondrocytes stimulated with LPS. These effects were reverted by AM630, a CB2 receptor antagonist.

These results suggest that BCP ameliorates arthritis through a cross-talk between CB2 and PPAR-γ.”

Is Cannabidiol a Promising Substance for New Drug Development? A Review of its Potential Therapeutic Applications.

Critical Reviews™ in Eukaryotic Gene Expression

“The pharmacological importance of cannabidiol (CBD) has been in study for several years.

CBD is the major nonpsychoactive constituent of plant Cannabis sativa and its administration is associated with reduced side effects.

Currently, CBD is undergoing a lot of research which suggests that it has no addictive effects, good safety profile and has exhibited powerful therapeutic potential in several vital areas.

It has wide spectrum of action because it acts through endocannabinoid receptors; CB1 and CB2 and it also acts on other receptors, such as GPR18, GPR55, GPR 119, 5HT1A, and TRPV2.

This indicates its therapeutic value for numerous medical conditions because of its neuroprotective and immunomodulatory properties.

Potential therapeutic applications of CBD include, analgesic, anti-inflammatory, anxiolytic, anti-arthritic, anti-depressant, anti-Alzheimer disease, anti-ischemic, neuroprotective, and anti-fibrotic.

More promising areas appear to include diabetes and cancer where CBD exhibits lesser side effects and more therapeutic benefits as compared to recent available medical therapies.

Hence, CBD is a promising substance for the development of new drug. However further research and clinical studies are required to explore its complete potential.”

Comparative in silico analyses of Cannabis sativa, Prunella vulgaris and Withania somnifera compounds elucidating the medicinal properties against rheumatoid arthritis

Cover image

“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.”

Cannabinoids: novel therapies for arthritis?

“A key feature of osteoarthritis and rheumatoid arthritis is the loss of articular cartilage.

Cartilage breakdown is mediated by complex interactions of proinflammatory cytokines, such as IL-1, inflammatory mediators, including nitric oxide and prostaglandin E(2), and proteases, including matrix metalloproteinases and aggrecanases, such as ADAMTS-4 and -5.

Cannabinoids have been shown to reduce joint damage in animal models of arthritis.

They have also been shown to prevent IL-1-induced matrix breakdown of collagen and proteoglycan, indicating that cannabinoids may mediate chondroprotective effects.

Cannabinoids produce their effects via several cannabinoid receptors and it is important to identify the key cannabinoids and their receptors that are involved in chondroprotection.

This review aims to outline the current and future prospects of cannabinoids as anti-arthritic therapeutics, in terms of their ability to prevent cartilage breakdown.”

The nonpsychoactive cannabis constituent cannabidiol is an oral anti-arthritic therapeutic in murine collagen-induced arthritis

Image result for pnas

“The therapeutic potential of cannabidiol (CBD), the major nonpsychoactive component of cannabis, was explored in murine collagen-induced arthritis (CIA).

CBD was administered after onset of clinical symptoms, and in both models of arthritis the treatment effectively blocked progression of arthritis. CBD was equally effective when administered i.p. or orally.

Clinical improvement was associated with protection of the joints against severe damage.

Taken together, these data show that CBD, through its combined immunosuppressive and anti-inflammatory actions, has a potent anti-arthritic effect in CIA.”
