Acetylcholine Receptors From Human Muscles as Pharmacological Target for ALS

Amyotrophic lateral sclerosis (ALS) is a fatal disease leading to motor neuron degeneration and progressive paralysis. Other studies have revealed defects in skeletal muscle even in absence of motor neuron anomalies, focusing on acetylcholine receptors (AChRs) and supporting the so-called "dying-back" hypothesis. Outcome of this study will be to understand if the endocannabinoid palmitoylethanolamide (PEA) can reduce the rundown of AChRs currents in ALS muscle, and if it can modify ALS patients' clinical and electrophysiological parameters.

Discovery and Preclinical Evaluation of a Novel Inhibitor of FABP5, ART26.12, Effective in Oxaliplatin-Induced Peripheral Neuropathy

Article

作者: Warren, George ; Yates, Andrew ; Osborn, Myles ; Bradshaw, Heather ; David-Pereira, Ana ; Kaczocha, Martin ; Duffy, Paul ; O'Sullivan, Saoirse E ; Ojima, Iwao ; Cohn, Daniel ; Tsantoulas, Christopher ; Ruston, Linette ; Johnson, Clare

Oxaliplatin-induced peripheral neuropathy (OIPN) is a dose-limiting toxicity characterised by mechanical allodynia and thermal hyperalgesia, without any licensed medications. ART26.12 is a fatty acid-binding protein (FABP) 5 inhibitor with antinociceptive properties, characterised here for the prevention and treatment of OIPN. ART26.12 binds selectively to FABP5 compared to FABP3, FABP4, and FABP7, with minimal off-target liabilities, high oral bioavailability, and a NOAEL of 1,000 mg/kg/day in rats and dogs. In an established preclinical OIPN model, acute oral dosing (25-100 mg/kg) showed a cannabinoid receptor type 1 (CB₁)-dependent anti-allodynic effect lasting up to 8 hours (persisting longer than plasma exposure to ART26.12). Antagonists of cannabinoid receptor type 2 (CB₂), peroxisome proliferator-activated receptor alpha, and transient receptor potential cation channel subfamily V member 1 (TRPV1) may have also been implicated. Twice daily oral dosing (25 mg/kg bis in die (BID) for 7 days) showed anti-allodynic effects in an established OIPN model without the development of tolerance. In a prevention paradigm, coadministration of ART26.12 (10 and 25 mg/kg BID for 15 days) with oxaliplatin prevented thermal hyperalgesia, mitigated mechanical allodynia, and attenuated OXA-induced weight loss. Multi-scale analyses revealed widespread lipid modulation, particularly among N-acyl amino acids in the spinal cord, including potential analgesic mediators. Additionally, ART26.12 administration led to upregulation of ion channels in the periaqueductal grey, and broad translational upregulation within the plasma proteome. These results show promise that ART26.12 is a safe and well-tolerated candidate for the treatment and prevention of OIPN through lipid modulation. PERSPECTIVE: Inhibition of fatty acid-binding protein 5 (FABP5) is a novel target for reducing pain associated with chemotherapy. ART26.12 is a safe and well-tolerated small molecule FABP5 inhibitor effective at preventing and reducing pain induced with oxaliplatin through lipid modulation and activation of cannabinoid receptors.

BackgroundThe metacarpophalangeal joint undergoes enormous loading during locomotion and can therefore often become inflamed, potentially resulting in osteoarthritis (OA). There are studies indicating that the endocannabinoid system (ECS) modulates synovium homeostasis, and could be a promising target for OA therapy. Some cannabinoid receptors, which modulate proliferative and secretory responses in joint inflammation, have been functionally identified in human and animal synovial cells.ObjectiveTo characterize the cellular distribution of the cannabinoid receptors 1 (CB1R) and 2 (CB2R), and the cannabinoid-related receptors transient receptor potential vanilloid type 1 (TRPV1), G protein-related receptor 55 (GPR55) and peroxisome proliferator-activated receptor alpha (PPARα) in the synovial membrane of the metacarpophalangeal joint of the horse.AnimalsThe dorsal synovial membranes of 14 equine metacarpophalangeal joints were collected post-mortem from an abattoir.Materials and methodsThe dorsal synovial membranes of 14 equine metacarpophalangeal joints were collected post-mortem from an abattoir. The expression of the CB1R, CB2R, TRPV1, GPR55, and PPARα in synovial tissues was studied using qualitative and quantitative immunofluorescence, and quantitative real-time reverse transcriptase PCR (qRT-PCR). Macrophage-like (MLS) and fibroblast-like (FLS) synoviocytes were identified by means of antibodies directed against IBA1 and vimentin, respectively.ResultsBoth the mRNA and protein expression of the CB2R, TRPV1, GPR55, and PPARα were found in the synoviocytes and blood vessels of the metacarpophalangeal joints. The synoviocytes expressed the mRNA and protein of the CB1R in some of the horses investigated, but not in all.Conclusions and clinical importanceGiven the expression of the CB1R, CB2R, TRPV1, GPR55, and PPARα in the synovial elements of the metacarpophalangeal joint, these findings encouraged the development of new studies supporting the use of molecules acting on these receptors to reduce the inflammation during joint inflammation in the horse.

作者: England, Timothy J. ; Stone, Nicole L. ; O'Sullivan, Saoirse E.

Background and Objectives: Preclinical studies have shown cannabidiol is protective in models of ischemic stroke. Based on results from our recent systematic review, we investigated the effects of two promising neuroprotective phytocannabinoids, cannabigerol (CBG) and cannabidivarin (CBDV), on cells of the blood-brain barrier (BBB), namely human brain microvascular endothelial cells (HBMECs), pericytes, and astrocytes. Experimental Approach: Cultures were subjected to oxygen-glucose deprivation (OGD) protocol to model ischemic stroke and cell culture medium was assessed for cytokines and adhesion molecules post-OGD. Astrocyte cell lysates were also analyzed for DNA damage markers. Antagonist studies were conducted where appropriate to study receptor mechanisms. Results: In astrocytes CBG and CBDV attenuated levels of interleukin-6 (IL-6) and lactate dehydrogenase (LDH), whereas CBDV (10 nM-10 μM) also decreased vascular endothelial growth factor (VEGF) secretion. CBDV (300 nM-10 μM) attenuated levels of monocyte chemoattractant protein (MCP)-1 in HBMECs. In astrocytes, CBG decreased levels of DNA damage proteins, including p53, whereas CBDV increased levels of DNA damage markers. Antagonists for CB₁, CB₂, PPAR-γ, PPAR-α, 5-HT1_A, and TRPV1 had no effect on CBG (3 μM) or CBDV (1 μM)-mediated decreases in LDH in astrocytes. GPR55 and GPR18 were partially implicated in the effects of CBDV, but no molecular target was identified for CBG. Conclusions: We show that CBG and CBDV were protective against OG mediated injury in three different cells that constitute the BBB, modulating different hallmarks of ischemic stroke pathophysiology. These data enhance our understanding of the protective effects of CBG and CBDV and warrant further investigation into these compounds in ischemic stroke. Future studies should identify other possible neuroprotective effects of CBG and CBDV and their corresponding mechanisms of action.

SciSparc Announces Israeli Ministry of Health Approval to Conduct its Clinical Trial in Autism Spectrum Disorder

The trial's objectives are to evaluate the safety, tolerability and efficacy of SciSparc's SCI-210 in children and adolescents with ASD TEL AVIV, Israel, Aug. 08, 2022 (GLOBE NEWSWIRE) -- SciSparc Ltd. (Nasdaq: SPRC) ("Company" or "SciSparc"), a specialty clinical-stage pharmaceutical company focusing on the development of therapies to treat disorders of the central nervous system, today announced that it has received approval from the Israeli Ministry of Health to conduct the Company’s clinical trial for SCI-210 in patients suffering from autism spectrum disorder ("ASD"). Recently, the Company announced it received approval from the Ethics Committee of The Soroka University Medical Center, in Be'er-Sheva, Israel, to conduct the Company’s clinical trial. “We are pleased to achieve another important milestone that brings us one step closer toward initiation of our clinical trial in ASD,” commented Oz Adler, SciSparc's Chief Executive Officer. "ASD symptoms in pediatric patients may cause a sever decrease in life quality, for parents and children. We believe that our unique and proprietary SCI-210 has the potential to be a new treatment to reduce irritability and other conditions associated with ASD. Patients today have limited treatment options while the need for such treatment rapidly grows. Our drug candidates potentially enable us to provide effective, safer and more tolerable treatment with fewer side effects thanks to the lower doses of cannabinoids, boosted by the combination with CannAmide™, a mission always desirable but even more so when children are the target population." The trial will investigate the effect of the Company’s drug candidate SCI-210, a proprietary combination of cannabidiol (“CBD”) and CannAmide™, versus CBD monotherapy in treating ASD. The trial's objectives are to evaluate the safety, tolerability and efficacy of SCI-210 in children and adolescents with ASD in a designed 20-week, randomized, double-blind, placebo controlled with a cross-over clinical trial of 60 children. The trial has three primary efficacy end points: the Aberrant Behavior Checklist-Community (ABC-C) parent questionnaire; the Clinical Global Impressions-Improvement (CGI-I) performed by a clinician; and the effective therapeutic dose. ASD is a condition related to brain development that impacts how a person perceives and socializes with others, causing problems in social interaction and communication. The term "spectrum" in autism spectrum disorder refers to the wide range of symptoms and severity. The launch of the trial is pending further approvals by the Israeli Medical Cannabis Agency. About SciSparc Ltd. (NASDAQ: SPRC): SciSparc Ltd. is a specialty clinical-stage pharmaceutical company led by an experienced team of senior executives and scientists. SciSparc’s focus is on creating and enhancing a portfolio of technologies and assets based on cannabinoid pharmaceuticals.
