Embodiment 1

[0077] Add 10g of α-ketoglutarate and 5g of arginine into the aqueous solution, stir at room temperature until dissolved, and wait until the reaction is complete to obtain a reaction solution, which is directly freeze-dried to obtain the raw material drug, namely α-ketoglutarate- arginine salt.

Embodiment 2

[0079] Add 8g of α-ketoglutarate and 6g of arginine into water, heat to dissolve at 60°C, filter, cool the filtrate to crystallize, filter, collect the solid, and obtain the raw material drug, ie, α-ketoglutarate-arginine salt.

Embodiment 3

[0081] Add 5g of α-ketoglutaric acid and 7g of arginine into the aqueous solution, stir at room temperature until dissolved, and wait until the reaction is complete to obtain a reaction solution, which is directly freeze-dried to obtain the raw material drug, namely α-ketoglutarate- arginine salt.

Abstract

The invention relates to an alpha-ketoglutaric acid-arginine salt, the preparing process and use thereof, wherein the salt is prepared through combining alpha-ketoglutaric acid and arginine with a preferred ratio of 1:1 and 1:2. Pharmacological experiment shows that, the salt can be used for treating liver damages.

Description

technical field [0001] The invention belongs to the field of medicine and pharmacy, and in particular relates to a preparation method of an alpha-ketoglutarate-arginine salt preparation and its application in treating liver diseases. Background technique [0002] α-ketoglutarate-arginine salt, also known as arginine-α-ketoglutarate, AKG, is a white powder, easily soluble in water. α-Ketoglutaric acid-arginine salt has the ability to store endogenous glutamine and improve glutamine synthesis, which can promote protein synthesis in critically ill patients and maintain patient weight and energy. [0003] α-Ketoglutaric acid is an important substance in the metabolism of substances and energy in organisms. It is the hub of the metabolic connection and interconversion of sugar, lipids, and certain amino acids. 2 And the key substance of the main pathway of energy. α-ketoglutaric acid is unstable under alkaline conditions and is easy to form a salt with organic bases, so α-ketog...
