Abstract

The invention discloses a novel method for preparing high-purify creatine phosphate sodium. The preparation method comprises the following steps of: (1) generating fat-soluble creatinine phosphoric acid carboxylic acid mixed anhydride by using creatinine phosphorus oxychloride and carboxylate in an organic solvent; (2) making the creatinine phosphoric acid carboxylic acid mixed anhydride react with a sodium hydroxide aqueous solution, and crystallizing to obtain creatinine sodium phosphate; and (3) hydrolyzing the creatinine sodium phosphate in a sodium hydroxide aqueous solution for performing ring opening; neutralizing an organic carboxylic acid, and crystallizing to obtain creatine phosphate sodium. The prepared creatine phosphate sodium prepared with the method has high purity, high yield, simple purification steps, low time consumption, short production period; and heavy metals are not left in a product, and the safety of clinical administration is ensured.

Description

Technical field: [0001] The invention relates to a new method for preparing high-purity creatine phosphate sodium. Background technique: [0002] Phosphocreatine is a type of High Energy Phosphate Compounds , is a cardioprotective agent. [0003] Currently, creatine phosphate production methods include enzymatic synthesis, biological extraction and chemical synthesis. [0004] Although the conditions of enzymatic synthesis are mild, it is difficult to control, and the free enzyme protein also increases the difficulty of purification. [0005] The biological extraction method mainly extracts creatine phosphate from animal muscle tissue, but the content in the animal body is low, and the extraction cost is high. [0006] Chemical synthesis is currently a major way to produce creatine phosphate sodium. [0007] "Journal of Harbin University of Science and Technology" 2004, Volume 9, No. 4, had an article proposing to generate creatine phosphate by adding phosphorus oxychlor...
