This article by Dr. Maria Digiacomo has been published in The Open Medicinal Chemistry Journal, Volume 11, 2017 Diabetes mellitus (DM) is probably one of the oldest known diseases and the incidence has been increasing steadily all over the world. This metabolic disease is characterized by chronic hyperglycemia due to defect in insulin secretion and/or insulin action. The etiopathology is very complex and is closely related with long-term damage, dysfunction, and failure of various organs, such as the eyes, kidneys, nerves, heart, and blood vessels. Strong epidemiological evidence suggest a relationship between blood sugar levels and the onset of diabetes complications, in fact, excess glucose in the body leads to conversion of sugar into its corresponding alcohol, namely sorbitol, via the polyol pathway. The activation of this pathway is dependent on the enzyme aldose reductase (ARL2) and thus its inhibition should be prevented or delay the onset of both micro- and macrovascular complications such as retinopathy, peripheral vascular disease and coronary artery disease. Currently, only the carboxylic acid epalrestat, an aldose reductase inhibitor (ARI), is available on the market and used for the treatment of diabetic neuropathy in Japan, India and China. Many ARIs have shown to be clinically unsuccessful because of adverse pharmacokinetics or toxic side-effects. In this study, we described the design, synthesis and biological evaluation of three small series of spirobenzopyran acetic acid derivatives, proposed as a scaffold for novel ALR2 inhibitors. Most of the new ARIs proved to inhibit the target enzyme, showing IC50 values in the micromolar/low micromolar range, without affecting the activity of another important enzyme, namely ARL1, which plays a detoxifying role in metabolic processes involved in the physiological homeostasis. These results suggested that the spirobenzopyran scaffold represents a new and promising tool that could pave the way to the discovery of novel and effective ARIs.

Research led by the University of Adelaide is paving the way for safer and more effective drugs to treat type 2 diabetes, reducing side effects and the need for insulin injections. Two studies, published in the Journal of Medicinal Chemistry and BBA-General Subjects, have shown for the first time how new potential anti-diabetic drugs interact with their target in the body at the molecular level. These new potential drugs have a completely different action than the most commonly prescribed anti-diabetic, Metformin, which acts on the liver to reduce glucose production, and are potentially more efficient at reducing blood sugar. They target a protein receptor known as PPARgamma found in fat tissue throughout the body, either fully or partially activating it in order to lower blood sugar by increasing sensitivity to insulin and changing the metabolism of fat and sugar. "Type two diabetes is characterised by resistance to insulin with subsequent high blood sugar which leads to serious disease. It is usually associated with poor lifestyle factors such as diet and lack of exercise," says lead researcher Dr John Bruning, with the University's School of Biological Sciences and Institute for Photonics and Advanced Sensing. "Prevalence of type 2 diabetes in Australia alone has more than tripled since 1990, with an estimated cost of $6 billion a year. The development of safe and more efficient therapeutics is therefore becoming increasingly important. "People with severe diabetes need to take insulin but having to inject this can be problematic, and it's difficult to get insulin levels just right. It's highly desirable for people to come off insulin injections and instead use oral therapeutics." The first study, in collaboration with The Scripps Research Institute in Florida, US, describes an honours research project by Rebecca Frkic, where 14 different versions of a drug which partially activates PPARgamma were produced. Partial activation can have the benefit of fewer side-effects than full activation. The original drug, INT131, is currently being tested in clinical trials in the US but some of the versions produced at the University of Adelaide have increased potency compared to the original, with the potential to further improve the treatment of type 2 diabetes. "A major finding of this study was being able to show which regions of the drug are most important for interacting with the PPARgamma receptor," says Dr Bruning. "This means we now have the information to design modified drugs which will work even more efficiently." The second study, in collaboration with Flinders University, used X-ray crystallography to demonstrate for the first time exactly how a potential new drug, rivoglitazone, binds with the PPARgamma receptor. Rivoglitazone fully activates PPARgamma but has less side effects than others with this mode of action. "Showing how this compound interacts with its target is a key step towards being able to design new therapeutics with higher efficiencies and less side-effects," says lead author Dr Rajapaksha, from Flinders University School of Medicine (now at La Trobe University). "Lack of structural information was hampering determination of the precise mechanisms involved."

SEATTLE, WA--(Marketwired - May 16, 2017) - CFN Media Group ("CFN Media"), the leading agency and digital media network dedicated to legal cannabis, today announced publication of an article covering ABcann Global Corp. (TSX VENTURE: ABCN) following its going-public transaction. There are about 40 licensed producers that have received approval from Health Canada to cultivate and sell medical cannabis to consumers. The largest company in the space is Canopy Growth Corp., which has become the first cannabis 'unicorn' with a valuation that's well over C$1 billion. Many other licensed producers are close to achieving these kinds of valuations as they ramp up production and revenue. ABcann Global is priced significantly lower by comparison with a market capitalization of about C$85 million, despite being one of the first licensed producers approved by Health Canada in 2014. The company hasn't scaled up its production as quickly as other LPs, but it has signed high-profile partnerships with companies like Syqe Medical Inc. -- the innovator behind the first metered dosage inhaler -- and developed some of the highest yields in the industry. In addition, the company has the cash on hand to significantly expand its capacity over the near-term. Management anticipates that its Van Luven facility will double its capacity, to about 29,000 square feet, this year while the Kimmet facility will come online next year with a 150,000 square foot presence. ABcann Global has an experienced management team that's well-positioned to execute on plans to become a leader in the space. Chairman Ken Clement has developed a strong rapport with Health Canada and cultivated several strategic partnerships around the world. His goal of standardizing production and doses of cannabinoids has help shaped the company's unique focus relative to other licensed producers that are focused on simply maximizing production of commoditized products that will eventually be hard to compete against as the market grows. CEO Aaron Keay has over 10 years of experience across many different sectors, serving in corporate finance, senior management, and board member roles. With a history of raising over $250 million, Mr. Keay is well-positioned to help the company secure funding and grow. Mr. Keay is also joined by a seasoned executive management team with experience across areas of management, finance, and the operation of cannabis businesses. Finally, the company has developed a solid board of advisors that includes the 'father of cannabis', Dr. Raphael Mechoulam, Ph.D. Dr. Mechoulam is an organic chemist and professor of Medicinal Chemistry at the Hebrew University of Jerusalem. He's best known for being the first scientist to isolate tetrahydrocannabinol (THC) and then cannabidiol (CBD) in 1963. Dr. Mechoulam is joined by many other prominent researchers and scientists in the field. Canada's cannabis industry could be worth between $12.7 billion and $22.6 billion by 2020, according to Deloitte Canada, eclipsing the combined sales of beer, wine, and spirits. The country is widely expected to implement recreational legalization by early next year, which could open the market significantly beyond the medical users that are currently served under the Access to Cannabis for Medical Purposes Regulations -- or ACMPR. PI Financial believes that there could be a shortfall in supply with only about 40 companies licensed by Health Canada to grow and sell the drug. According to a recent report, the analyst reckons that LPs would need to cultivate a total of 610,000 kilograms to fulfill domestic and export demand by 2019. The problem is that existing capacity would fall short and lead to a 200,000 kilogram shortfall and it could be difficult to onboard enough new LPs.

Today, results from a post hoc analysis of data from the SCALE Maintenance trial were presented at the 24th European Congress on Obesity (ECO) 2017. In the trial, adults who lost at least 5% of their initial weight during a low- calorie run-in period were randomised to receive Saxenda® (liraglutide 3 mg) or placebo. After 16 weeks of treatment with Saxenda®, participants who lost an additional 5% or more of their body weight (defined as 'early responders') were more likely to maintain weight loss and achieve greater additional weight loss over 56 weeks, compared with people losing less than 5% body weight after 16 weeks of Saxenda® treatment ('early non-responders'). "In the obesity specialist setting, low-calorie diets combined with increased physical activity are commonly used to induce an initial weight loss in people with obesity. However, when the initial weight loss reaches a plateau and patients enter the 'weight maintenance phase' with less stringent caloric restriction, we often see that many experience weight regain," said Dr Sean Wharton, medical director at the Wharton Medical Clinic, Ontario and SCALE clinical trial investigator. "As a consequence, pharmacotherapy can be used to help people with obesity in maintaining the weight loss that has already been achieved by a low-calorie diet and increased physical activity. These data are very encouraging to clinicians in this specialist setting, because they show that early responders to Saxenda® are able to both maintain and achieve additional weight loss." Of those who completed 56 weeks of treatment with Saxenda®, 68% were early responders to Saxenda® at week 16 and 32% were early non-responders. In addition to weight loss achieved during the run-in period, early responders experienced 9.9% weight loss, compared with 0.0% in early non-responders at 56 weeks. Following 56 weeks of treatment, 91.7% of early responders and 47.1% of early non-responders, had maintained or lost additional weight following the run-in period. No early responders regained their run-in weight loss over 56 weeks of treatment with Saxenda®, compared with 3.9% of early non-responders. There were similar incidences of total adverse events in early responders (92.7%) and early non-responders (91.0%). Gastrointestinal adverse events were more frequent in early responders compared with early non-responders (78.9% vs 62.7%). Saxenda® was generally well-tolerated, with observed side effects in line with previous trials. Obesity is a disease,that requires long-term management. It is associated with many serious health consequences and decreased life expectancy., Obesity-related comorbidities include type 2 diabetes, heart disease, obstructive sleep apnoea (OSA) and certain types of cancer.,,It is a complex and multi-factorial disease that is influenced by physiological, psychological, environmental, socio-economic and genetic factors. The global increase in the prevalence of obesity is a public health issue that has severe cost implications to healthcare systems. In 2014, 13% of adults, or approximately 600 million adults, were living with obesity. Saxenda® (liraglutide 3 mg) is a once-daily glucagon-like peptide-1 (GLP-1) analogue with 97% similarity to naturally occurring human GLP-1, a hormone that is released in response to food intake. Like human GLP-1, Saxenda® regulates appetite by increasing feelings of fullness and satiety, while lowering feelings of hunger and prospective food consumption, thereby leading to reduced food intake. As with other GLP-1 receptor agonists, Saxenda® stimulates insulin secretion and lowers glucagon secretion in a glucose-dependent manner. Saxenda® was evaluated in the SCALE (Satiety and Clinical Adiposity - Liraglutide Evidence) phase 3a clinical trial programme. In the EU, Saxenda® is indicated as an adjunct to a reduced-calorie diet and increased physical activity for weight management in adult patients with an initial BMI of ≥30 kg/m2 (obese), or ≥27 kg/m2 to <30 kg/m2 (overweight) in the presence of at least one weight-related comorbidity such as dysglycaemia (prediabetes or type 2 diabetes mellitus), hypertension, dyslipidaemia or obstructive sleep apnoea. Guidance is given in the label that treatment with Saxenda® should be discontinued after 12 weeks on the liraglutide 3.0 mg/day dose, if patients have not lost at least 5% of their initial body weight. In the SCALE Maintenance clinical trial, adults with obesity (BMI ≥30 kg/m2) or who were overweight (BMI ≥27 kg/m2 to <30 kg/m2) with comorbidities (dyslipidaemia and/or hypertension), who lost at least 5% of their initial weight during a low-calorie diet (1200-1400 kcal/day) run-in period, were randomised to receive Saxenda® (n=212) or placebo (n=210) for 56 weeks, both as an adjunct to a reduced-calorie diet and increased physical activity. Novo Nordisk's phase 3 development programme, called SCALE, investigated liraglutide 3 mg for weight management. The SCALE clinical development programme consisted of four, placebo-controlled, multinational trials called: SCALE Obesity and Prediabetes, SCALE Diabetes, SCALE Sleep Apnoea and SCALE Maintenance.[12-16] Novo Nordisk is a global healthcare company with more than 90 years of innovation and leadership in diabetes care. This heritage has given us experience and capabilities that also enable us to help people defeat other serious chronic conditions: haemophilia, growth disorders and obesity. Headquartered in Denmark, Novo Nordisk employs approximately 42,000 people in 77 countries and markets its products in more than 165 countries.

A molecule produced by a Thai liver parasite could be the solution to those non-healing wounds - and scientists from the Australian Institute of Tropical Health and Medicine (AITHM) are now able to produce a version of the molecule on a large enough scale to make it available for laboratory tests and eventually clinical trials. The molecule is granulin, one of a family of protein growth factors involved with cell proliferation. "It's produced by a parasitic liver fluke, Opisthorchis viverrini, which originally came to our attention because it causes a liver cancer that kills 26,000 people each year in Thailand," parasitologist Dr Michael Smout said. As part of their work on a potential vaccine to protect people from the parasite, Dr Smout and colleagues established that the granulin it produces has a hidden talent - it supercharges healing. "We realised the molecule, discovered in worm spit, could offer a solution for non-healing wounds, which are a problem for diabetics, smokers and the elderly," he said. With fellow researchers from the AITHM at James Cook University in Cairns, Dr Smout has been investigating ways to produce granulin in sufficient quantities for larger-scale testing. The team first tried recombinant DNA techniques, effectively inserting granulin into bacteria, with the aim of producing plentiful supplies of a reliable copy of the molecule. "Unfortunately, granulin didn't perform well when we introduced it to E. coli bacteria, so we couldn't use recombinant techniques to produce a testable supply," said Professor Norelle Daly, whose research involves exploring the potential of peptides as drug candidates for therapeutic applications. "We had to go back to the drawing board and find a way to synthesize part of the molecule - to build our own version of designer worm spit," she said. The researchers worked to establish which parts of the molecule were critical to wound healing, and to find a way to reproduce the active parts of granulin molecules (peptides). Nuclear Magnetic Resonance (NMR) spectroscopy revealed the molecule's complex shape: a string of amino acids bent into a twisted 3D shape that includes hairpin bends. "In biology the shape and fold of a molecule can be critical to its function," Dr Smout said. "Getting the fold right is important - it can be like the difference between throwing a well folded paper plane, or tossing a crumpled ball of paper." After testing different segments and structures, the team concluded that those hairpin bends were the key. "They're held in the twisted 3-D shape by disulfide bonds, and surprisingly we've found that by introducing an extra, non-native, bond we can produce peptides that hold the right shape to promote healing," Professor Daly said. "You could say we've found an extra fold that helps our peptide paper plane fly straight and target wounds." The lab-produced granulin peptides have shown great promise in tests, driving cell proliferation in human cells grown in lab plates, and demonstrating potent wound healing in mice. Now that they can mass-produce perfectly folded, wound-healing peptides, the researchers are looking for potential partners as they progress towards further testing and eventually clinical trials. "We have plenty of work to do before clinical trials, but we're confident we have a very strong contender for what could one day be a cream that a diabetic could apply at home, avoiding a lengthy hospital stay and possible amputation," said Professor Alex Loukas, whose work includes the investigation of hookworm proteins to treat autoimmune and allergic diseases. "A take-home cream would be a great step forward for those with chronic wounds, and it would also save our health system a great deal of money. "One in every seven diabetics in Australia will have a non-healing wound at some point, and many suffer amputations as a result. It's estimated the long hospital stays involved in treating chronic wounds cost our healthcare system AU$3.7 billion per year." The research is published in the latest edition of the Journal of Medicinal Chemistry. More information: Paramjit S. Bansal et al.
