主要方法:

在体内研究使用高脂肪和高胆固醇饮食诱导的NAFLD小鼠模型.
蛋白质和RNA测序分析以阐明分子途径.
在体外试验测试以确定AKBA的直接相互作用和抑制单糖醇脂酶 (MGLL).

主要成果:

在小鼠中,AKBA治疗显著缓解了NAFLD进展,体重增加和胰岛素抵抗.
在肝细胞中,AKBA直接向并抑制单糖醇脂酶 (MGLL).
结构分析证实AKBA与MGLL的特定残留物 (GLU60,MET64,THR279,PHE283) 相结合.
AKBA的治疗效果取决于MGLL活性,正如MGLL缺陷模型所显示的那样.

结论:

AKBA被确定为MGLL的新型和强大的抑制剂.

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...
