Hydrogen Peroxide

OXFORD, United Kingdom, Oct. 10, 2024 (GLOBE NEWSWIRE) -- MitoRx Therapeutics (MitoRx), a platform biotechnology company developing novel mitochondrial-targeted sulfide-donor therapeutics (mtH2SD) in obesity-related disorders and myopathies announces a publication in Elsevier’s prestigious biomedical sciences journal Pharmacological Research. The work led by collaborators at Jagiellonian University Medical College showed that in a preclinical mouse study involving high-fat diet (HFD)-induced obesity, the company’s mtH2SD compound AP39, significantly slowed the rate of gain in weight. This is the first comprehensive study designed to test whether mitochondrial sulfide donors could address weight gain and fatty liver (steatosis). Mounting evidence suggests that hydrogen sulfide is an important signalling molecule in the liver, regulating lipid metabolism and mitochondrial function, but its direct delivery to mitochondria had not been investigated as a therapeutic strategy in obesity-related metabolic disorders. This is what the Pharmacological Research paper examined. MitoRx’s CSO, Prof Matt Whiteman, and their Senior Discovery Chemist, Dr. Roberta Torregrossa, with co-inventor Dr. Mark Wood at the University of Exeter are co-authors on the paper. It showed that treatment with AP39 reduced weight gain in animals fed HFD by 32% at the end of the research. (1) AP39 is a versatile mtH2SD tool compound that mediates very large and statistically significant reductions in liver steatosis, large and significant reductions in triglycerides, reductions in de novo lipogenesis, reductions in inflammatory markers, and significant downregulation of known liver proteomic markers of weight gain and the development of obesity, indicating mtH2SD-mediated downregulation mTOR/SREBP-1/SCD1 pathway alleviates obesity. MitoRx is developing undisclosed next-generation mtH2SDs to take to the clinic. Importantly, this modality is both muscle protective including in a severe fibrotic muscle atrophy model and is also anti-obesogenic. With this double therapeutic benefit, MitoRx’s next-gen mtH2SDs could potentially address the loss of lean muscle mass which is a serious side effect of marketed GLP-1 receptor agonist drugs in general, especially with age. This approach could be applicable in sarcopenic (age-related muscle mass and strength loss) obesity while also addressing muscle wasting in obese patients in general. Dr. Jon Rees, Chief Executive Officer of MitoRx, said: “MitoRx is advancing its first-in-class mitochondriotropic platform initially focused on myopathies and is now applying it to obesity offering a small molecule anti-obesogenic which is also muscle protective. This latest publication provides solid pre-clinical evidence that AP39 substantially suppressed the gain of weight in HFD-fed animals, suggesting a new pathway to alleviate obesity, whilst avoiding the muscle wasting side-effects that blight GLP-1 receptor agonist drugs. Powerful international research collaborations like this, with the talented team at Jagiellonian University’s Faculty of Medicine, help speed therapeutic advances to patients.” Dr. Aneta Stachowicz, Department of Pharmacology at the Faculty of Medicine, Jagiellonian University Medical College, Poland, and lead author of the Pharmacological Research paper, said: “Having comprehensively demonstrated that mitochondrial-targeted sulfide donors alleviate weight gain and significantly reduce multiple markers of obesity, we mark the beginning of a new era in the development of an innovative therapeutic approach for metabolic disease through the modulation of mitochondrial sulfide-signalling.” Matt Whiteman, Professor of Experimental Therapeutics at the University of Exeter Medical School, UK, and co-author of the study added: We discovered impaired sulfide metabolism in overweight patients with type 2 diabetes in 2010 (2) and we noticed that this impairment was driven by the amount of fat tissue these individuals were carrying; an observation since confirmed by many others. These findings suggested that treating this impairment with mtH2SD could potentially treat diabetes, obesity and complications arising from having too much fat in the body. It is gratifying to now translate those observations toward clinically viable drugs with MitoRx References: (1): Mitochondria-targeted hydrogen sulfide donor reduces fatty liver and obesity in mice fed a high fat diet by inhibiting de novo lipogenesis and inflammation via mTOR/SREBP-1 and NF-Kappa-B signaling pathways.

Neither a one-meter drop nor constant motion and vibration prevent the device from completing tests with near 100% accuracy, proving its utility at Point of Need™ in virtually any environment ALAMEDA, Calif., June 18, 2024 /PRNewswire/ -- Alveo Technologies, Inc. (Alveo), a leader in molecular sensing and diagnostics with its proprietary technology platform, today announced the results of rigorous testing that demonstrate the ruggedness of its portable molecular testing platform. Whether it fell from a significant height, endured temperature and humidity extremes, or was subjected to jarring vibrations that mimic vehicle transportation of virtually any type — the device continued to complete tests and produce accurate results. Alveo's platform has been designed to provide accurate, rapid test results at the point of need. The company tested its platform to demonstrate that it can perform reliably in harsh, real-world conditions, where markets, applications and use cases previously did not exist due to this unmet market need and requirement. Specifically, the Alveo platform underwent the following tests: Environmental resilience: The device was placed in controlled chambers at 5 degrees Celsius and 40 degrees Celsius at up to 95% humidity for 24 hours. Movement and vibration: At a third-party facility, the platform was subjected to constant motion and vibration for nearly four hours (233 minutes and 34 seconds), simulating what the device would experience in the back of a moving delivery truck. Drop testing: The device was dropped from up to 1 meter in height onto a hardwood board. Cleaning: The analyzer was wiped down 100s of times with five different common disinfectants, including commercial bleach, isopropyl alcohol and hydrogen peroxide. The results demonstrate that the Alveo platform can accurately perform tests in the field, under the most extreme of conditions. In the environmental resilience, drop, and cleaning tests, the device completed tests with 100% accuracy, and in the movement and vibration test, it also performed at 100% accuracy when the LED was facing up. When the LED was facing down during the vibration and movement test, it completed tests with 94% accuracy. The company is actively working on its next generation platform, enabling 360-degree capability with 100% accuracy. "These tests thoroughly demonstrate our platform's ability to provide consistent performance at the point of need, whether testing takes place in fields, on farms and in animal pens, remote locations, disaster zones, and beyond," said Shaun Holt, CEO at Alveo. "Our rugged design and innovative molecular detection technology make it possible for healthcare providers, veterinarians, growers, and public health officials to obtain rapid, accurate results at the point of need, enabling them to take immediate action to treat and contain diseases, bacteria, fungi, and other contaminants. Alveo is leading the way by delivering a system that works in harsh environments where fast, easy testing without compromise is needed most. This study verifies that we can produce PCR-like results for a whole new set of applications, use cases, and a much broader user base than traditional molecular diagnostic methods."
