摘要
现行教材中贝诺酯的合成基于Schotten-Baumann酯化反应,实验试剂SOCl2会转化生成HCl和SO2,环境友好性低,且实验步骤多.本改进实验利用碳二酰亚胺/4-DMAP缩合酯化反应一步合成贝诺酯,通过熔点测定、NMR、HPLC-MS等对产品进行结构表征与纯度测定,并进行基于大鼠血浆和胆汁的体内动态分析.同时验证了药物设计拼合原理,改进后的方法绿色高效,安全性明显提高.
Abstract
The current synthesis of benorilate typically involves the Schotten-Baumann esterification,which generates harmful gases HCl and SO2 from the reagent SOCl2,posing environmental concerns. Moreover,the process entails multiple steps. In this study,we have optimized a one-step method using EDCI/4-DMAP esterification for the synthesis of benorilate. The product's structure and purity were characterized through melting point determination,NMR,and HPLC-MS analysis,followed by in vivo dynamic evaluation in rats based on plasma and bile samples. This evaluation confirmed the principles of drug design. The improved method not only enhances efficiency but also significantly improves experimental safety.
