Discovery of potent, highly selective, and orally bioavailable factor XIa inhibitors for anticoagulant therapy.

Factor XIa (FXIa) has emerged as a promising target for novel anticoagulant development since inhibiting it can reduce thrombosis without significant bleeding risks. Despite a few FXIa inhibitors entering clinical trials, none have been approved for the market yet. Here, we present highly selective and orally bioavailable FXIa inhibitors derived from compound 1, 4-(5-chloro-2-(1H-tetrazol-1-yl)phenyl)-5-methoxypyridin-2(1H)-one.

Hepatoprotective effects of polysaccharide from Morchella esculenta are associated with activation of the AMPK/Sirt1 signaling pathway in mice with NAFLD.

The functional food application of edible fungus polysaccharides has been widely studied based on their variety of potential pharmacological activities. However, the hepatoprotective effects and mechanisms of Morchella esculenta polysaccharide against nonalcoholic fatty liver disease (NAFLD) remain unknown. A high-fat diet (HFD) fed C57BL/6 J mice for 8 weeks was employed to establish NAFLD with simple steatosis, methionine choline deficiency (MCD) diet for 4 weeks induced hepatic steatohepatitis and fibrosis.

Polyoxometalates Ameliorate Metabolic Dysfunction-Associated Steatotic Liver Disease by Activating the AMPK Signaling Pathway.

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), the most prevalent chronic liver disorder, has garnered increasing attention globally owing to its associated health complications. However, the lack of available therapeutic medications and inadequate management of complications in metabolic dysfunction-associated steatohepatitis (MASH) present significant challenges. There are little studies evaluating the effectiveness of POM in treating MASLD.

Intestinal Nogo-B reduces GLP1 levels by binding to proglucagon on the endoplasmic reticulum to inhibit PCSK1 cleavage.

Glucagon-like peptide 1 (GLP1), which is mainly processed and cleaved from proglucagon in enteroendocrine cells (EECs) of the intestinal tract, acts on the GLP1 receptor in pancreatic cells to stimulate insulin secretion and to inhibit glucagon secretion. However, GLP1 processing is not fully understood. Here, we show that reticulon 4B (Nogo-B), an endoplasmic reticulum (ER)-resident protein, interacts with the major proglucagon fragment of proglucagon to retain proglucagon on the ER, thereby inhibiting PCSK1-mediated cleavage of proglucagon in the Golgi.

Berberine protects mice against type 2 diabetes by promoting PPARγ-FGF21-GLUT2-regulated insulin sensitivity and glucose/lipid homeostasis.

Type 2 diabetes (T2D) is a chronic, burdensome disease that is characterized by disordered insulin sensitivity and disturbed glucose/lipid homeostasis. Berberine (BBR) has multiple therapeutic actions on T2D, including regulation of glucose and lipid metabolism, improvement of insulin sensitivity and energy expenditure. Recently, the function of BBR on fibroblast growth factor 21 (FGF21) has been identified.

Glabridin Ameliorates Alcohol-Caused Liver Damage by Reducing Oxidative Stress and Inflammation via p38 MAPK/Nrf2/NF-κB Pathway.

Licorice is a traditional and versatile herbal medicine and food. Glabridin (Gla) is a kind of isoflavone extracted from the licorice root, which has anti-obesity, anti-atherosclerotic, and antioxidative effects. Alcoholic liver disease (ALD) is a widespread liver disease induced by chronic alcohol consumption.

Novel flavonoid 1,3,4-oxadiazole derivatives ameliorate MPTP-induced Parkinson's disease via Nrf2/NF-κB signaling pathway.

Parkinson's disease (PD) is a progressive neurodegenerative disorder with a complex etiology. Neuroinflammation and oxidative stress are important factors driving the progression of PD. It has been reported that 1,3,4-oxadiazole and flavone derivatives have numerous biological functions, especially in the aspect of anti-inflammatory and antioxidant.

Compound Danshen Dripping Pill inhibits hypercholesterolemia/atherosclerosis-induced heart failure in ApoE and LDLR dual deficient mice multiple mechanisms.

Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown.

Roxadustat alleviates nitroglycerin-induced migraine in mice by regulating HIF-1α/NF-κB/inflammation pathway.

Sensitization of central pain and inflammatory pathways play essential roles in migraine, a primary neurobiological headache disorder. Since hypoxia-inducible factor-1α (HIF-1α) is implicated in neuroprotection and inflammation inhibition, herein we investigated the role of HIF-1α in migraine. A chronic migraine model was established in mice by repeated injection of nitroglycerin (10 mg/kg, i.

Polysaccharide MCP extracted from Morchella esculenta reduces atherosclerosis in LDLR-deficient mice.

The pharmaceutical application of fungal polysaccharides has been extensively studied based on their multiple biological activities. However, the effect of Morchella esculenta polysaccharides on the development of atherosclerosis remains unknown. This study aims to investigate the anti-atherosclerotic effect of a novel polysaccharide (MCP) extracted from Morchella esculenta.

Apigenin protects mice against 3,5-diethoxycarbonyl-1,4-dihydrocollidine-induced cholestasis.

Cholestasis can induce liver fibrosis and cirrhosis. Apigenin has anti-oxidant and anti-inflammatory effects. Herein, we determined whether apigenin can protect mice against cholestasis.

Salvia miltiorrhiza in Anti-diabetic Angiopathy.

Salvia miltiorrhiza, a traditional Chinese medicine, also named Danshen in China, is widely used for the treatment of cardiovascular disease. It demonstrates multiple biological functions, such as anti-oxidative stress, anti-inflammation and anti-thrombosis. Diabetic angiopathy is one of the diabetic complications with macro- and microangiopathy.

LongShengZhi Capsule Attenuates Alzheimer-Like Pathology in APP/PS1 Double Transgenic Mice by Reducing Neuronal Oxidative Stress and Inflammation.

Alzheimer's disease (AD) is the most common form of dementia in the elderly. It may be caused by oxidative stress, inflammation, and cerebrovascular dysfunctions in the brain.
