Article Abstract

Flow chemistry-based syntheses of deuterium-labeled analogs of important antidiabetic chalcones were achieved via highly controlled partial C≡C bond deuteration of the corresponding 1,3-diphenylalkynones. The benefits of a scalable continuous process in combination with on-demand electrolytic D2 gas generation were exploited to suppress undesired over-reactions and to maximize reaction rates simultaneously. The novel deuterium-containing chalcone derivatives may have interesting biological effects and improved metabolic properties as compared with the parent compounds.

The treatment of metabolic dysfunction-associated steatotic liver disease involves physical activity, weight loss, and management of comorbidities (diabetes, hypertension, dyslipidemia). In 2024, the American Food and Drug Administration provisionally approved resmetirom for metabolic dysfunction-associated steatohepatitis. Other promising molecules are being evaluated (glucagon-like peptide 1 receptor agonists, fibroblast growth factor 21 agonist).

Flavonoids refer to a large class of secondary metabolites with a unique skeleton comprising two aromatic rings linked together by a C unit. This class of compounds is largely distributed in plants and rarely occurs in fungi. Some of these compounds are directly bonded to prenyl units.

Metabolic dysfunction associated steatohepatitis (MASH), formerly known as NASH, represents one of the leading causes of chronic liver disease worldwide. Its high prevalence is driven by insulin resistance, obesity and type 2 diabetes (T2D) and is associated with cardiovascular disease. The main driver of liver damage is fat accumulation in hepatocytes leading to inflammation and fibrosis development.

Sweet tea, the leaves of Lithocarpus litseifolius (Hance) Chun, received widespread attention for its edible and healthy values. This study employed non-targeted (UPLC-Q-Orbitrap-MS/MS) and quantitative (UPLC-QqQ-MS/MS) analyses to investigate the influence of harvest timing and geographic origin on its metabolite profile, flavor, and bioactivity. Among 505 identified metabolites, flavonoids and dihydrochalcones exhibited significant variation across developmental stages and regions.

Obesity is associated with several comorbidities including Heart Failure with preserved Ejection Fraction (HFpEF), Metabolic dysfunction-Associated SteatoHepatitis (MASH), also termed MetALD when MASH patients have increased alcohol intake. The worldwide epidemic of obesity creates a constant need for new therapies and animal models to test their effectiveness. In the present study, we evaluated the effects of the GLP-1 receptor agonist semaglutide and the pan-PPAR agonist lanifibranor in the free choice diet induced obese MASH hamster, a preclinical model with human-like lipoprotein metabolism, MASH and HFpEF.
