Abstract

The invention discloses an application of 2-hydroxy-3-methylbutyric acid in weight and lipid reduction, belonging to the fields of biological medicine manufacture, biological medical application and functional food development. The invention provides an application of 2-hydroxy-3-methylbutyric acid and derivatives thereof in weight loss for the first time, and the compound can inhibit weight increase of mice in a high-fat diet-induced obesity model, reduce body fat and reduce fat cell area of the mice in the high-fat diet-induced obesity model. Compared with GLP-1 receptor weight-losing medicines, the weight-reducing effect is achieved by suppressing appetite, the compound 2-hydroxy-3-methylbutyric acid and derivatives thereof are not dependent on suppressing appetite, but are used for preventing and treating obesity by accelerating fat metabolism intervention, so that the weight-reducing effect is achieved, and side effects caused by the appetite intervention such as gastrointestinal discomfort, cardiovascular risk and the like are avoided. The invention provides a safe and effective new strategy for reducing weight and lipid.

Description

Application of 2-hydroxy-3-methylbutyric acid in weight and lipid reduction Technical Field The invention belongs to the fields of biological medicine manufacturing, biological medical application and functional food development, and in particular relates to application of 2-hydroxy-3-methylbutyric acid in weight and lipid reduction. Background In recent years, with the improvement of living standard and the change of dietary structure, the occurrence rate of overweight and obesity is continuously rising worldwide, and the trend of younger is presented. Obesity not only significantly increases the risk of chronic diseases such as type 2 diabetes, fatty liver, cardiovascular diseases and the like, but also is a main factor causing preventable diseases and disability, and has become a serious public health and socioeconomic burden. Therefore, the development of a safe, effective and long-term nutritional intervention scheme is of great significance in controlling body weight and improving related metabolic disorders. Some drugs are approved for obesity management, such as orlistat, semaglutin and the like, but have certain side effect risks generally, so that the feasibility of long-term use of the drugs is limited. For example, orlistat may cause gastrointestinal discomfort, liver dysfunction, etc., GLP-1 receptor agonist polypeptides often accompany adverse effects such as nausea, diarrhea, dizziness, decreased lean body mass (mainly muscle tissue consumption), etc., and there is a risk of hypoglycemia in some people. Therefore, functional ingredients having higher safety and suitable for pharmaceutical or functional food use are increasingly demanded. Disclosure of Invention Aiming at the problem that the existing weight-reducing medicine has side effect risk, the invention provides 2-hydroxy-3-methylbutyric acid (HIVA) as an active ingredient for regulating organism fat metabolism disorder diseases. 2-Hydroxy-3-methylbutyric acid (2-hydroxy-3-methylbutyric acid, HIVA) is a small molecular compound that naturally occurs in a variety of fermented foods, such as certain yogurt, cheese, wine, etc., and therefore has a certain safety basis as a dietary source. HIVA as a metabolite of valine in branched chain amino acids, studies have reported that it can be used as a marker reflecting insulin resistance and the risk of developing human type 2 diabetes (DANIEL N ET al., nat Commun. 2022; 13:1343). In addition, some studies have shown that HIVA can exert beneficial effects in stimulating bone formation, alleviating osteoporosis, etc. (Shuo L et al., J function foods.2025; 130:106905), and literature indicates that it can promote intestinal epithelial cell proliferation (Qiao Z et al., front Nutr.2022; 9:799053). Even though HIVA has been proposed to reduce the weight and blood lipid level of mice in an atherosclerosis model (CN 117919216A), HIVA has not been proposed at home and abroad to have the effects of reducing body weight and improving blood lipid, liver function, etc. in obese or overweight people caused by simple hyperlipidemia. 2-Hydroxy-3-methylbutanoic acid, also known as 2-hydroxyisovaleric acid (HIVA), has the formula C 5H10O3 and its molecular structural formula。 The present invention provides the use of 2-hydroxy-3-methylbutyric acid or a food or pharmaceutically acceptable derivative thereof in the manufacture of a medicament for the treatment or prevention of obesity/overweight. The invention further provides the use of 2-hydroxy-3-methylbutyric acid or a food acceptable derivative thereof for the preparation of a nutritional composition or a biomedical food for use in weight management, comprising reducing body fat content and/or reducing body weight. In an embodiment of the present invention, the nutritional composition is a composition containing one or more functional ingredients, optionally one or more of food acceptable carriers, auxiliary materials, excipients, diluents, fillers, sweeteners, flavoring agents, colorants, preservatives, stabilizers, emulsifiers, thickeners and the like, and is formulated and processed to further include a composition for supplementing nutrients needed by human body, regulating physiological functions of the human body or meeting specific nutritional requirements, wherein the nutritional composition can be a solid, semi-solid or liquid preparation, including but not limited to powder, granule, tablet, capsule, oral liquid, beverage, milk shake, meal replacement food, nutritional bar, and the nutrients include proteins, carbohydrates, fats, vitamins, minerals and dietary fibers. In an embodiment of the present invention, the biomedical food comprises one or more of proteins, carbohydrates, fats, vitamins, minerals, dietary fibers and other functional ingredients, and may further comprise food acceptable excipients, carriers, stabilizers, emulsifiers, flavoring agents. In an embodiment of the invention, the food or pharmaceutically acceptable derivative is se
