(2) Application in cardiovascular diseases
Pyridoxine Bnf is beneficial for some patients with cardiovascular disease. Homocysteine ​​(Hcy) is an intermediate metabolite of methionine metabolism. Abnormally elevated levels of Hcy in plasma can damage endothelial cells and blood vessels, and is a risk factor for various cardiovascular diseases. Vitamin B6 can promote the biosynthesis of nitric oxide (NO) in endothelial cells, reduce the level of Hcy in plasma, and is often combined with folic acid to treat homocysteinemia and the accompanying coronary heart disease, hypertension, and cerebral infarction A series of cardiovascular and cerebrovascular diseases.

(3) Application in gynecological diseases
Pyridoxine Bnf is a coenzyme synthesized by GABA and 5-hydroxytryptamine, which can reduce nerve excitability and relax uterine smooth muscle, so it can effectively treat female primary dysmenorrhea, and has the advantages of small side effects and low cost. Pyridoxine Bnf is also often combined with other drugs to form compound preparations, such as Diclegis (doxylamine succinate-pyridoxine hydrochloride, an oral sustained-release tablet) is effective for nausea and vomiting in pregnant women and has good tolerance sex.

Preparation of Pyridoxine Bnf

Pyridoxine Bnf is the most widely distributed form of vitamin B6 compounds in nature, and it is also the main component of this series of vitamin medicines. At present, the industry mainly adopts the oxazole method to produce pyridoxine hydrochloride. However, a large amount of phosphorus pentoxide will be used in this method, which will easily cause equipment damage and safety accidents, and also bring serious three wastes problems. Therefore, chemists have carried out optimization research on this process, such as getting rid of phosphorus pentoxide, Preparation of N-ethoxyoxalylalanine ethyl ester (replacing N-formylalanine ethyl ester (1)) by synchronous esterification of alanine and oxalic acid, using phosgene-triethylamine system as cyclizing agent Production of important intermediate ethyl 4-methyl-5methoxy-2-oxazolecarboxylate (2). In 2009, the process reform was further carried out, so that the synthesis of 4-methyl-5-ethoxy oxazole (3) did not require high vacuum vacuum distillation operation, and Diels-Alder cycloaddition with diethyl maleate was carried out , aromatization, reduction to obtain the target product, the total yield can reach 56%. In the above processes, the biggest disadvantage is that highly toxic and carcinogenic benzene is used as the reaction solvent. In 2003, Roche (Shanghai) Vitamin Co., Ltd. completely broke the traditional production process and successfully built the first domestic Pyridoxine Bnf production line that does not use benzene as a solvent. This is a major breakthrough in the production process of Pyridoxine Bnf. important meaning.
