摘要
建立了以马兜铃内酰胺Ⅰ为原料的溴化及交叉偶联二步有机合成工艺,粗产物经过 4 种溶剂除杂纯化,制得马兜铃酸Ⅰ(aristolochic acids Ⅰ,AAⅠ)的3 种脱氧核苷结合物产物AAⅠ-dA、AAⅠ-dG、AAⅠ-dC,2 步反应的收率均可达到90%,产物纯度均大于 98%,满足中药化学对照品定性定量要求.该工艺重复性好,适合放大制备,具有制备步骤短及纯化操作高效、勿需色谱分离、产品收率及纯度高等特点.相比其他方法,该方法优势显著,更适于马兜铃酸Ⅰ-脱氧核苷结合物化学对照品制备.新开发的工艺为马兜铃酸Ⅰ-脱氧核苷结合物对照品的制备提供了技术支撑,为相关毒理学研究提供了坚实的物质基础.
Abstract
A two-step synthetic process of bromination and cross-coupling with aristololactam Ⅰ as raw material was successfully developed.Three aristolactam Ⅰ-deoxyriboside adducts,namely AAⅠ-dA,AAⅠ-dG,and AAⅠ-dC were obtained after a sequential procedure of impurity removal and purification in four different solvents.The yield of the two-step reaction can reach 90%,and the pu-rity of the product is more than 98%,which can meet the requirements of qualitative and quantitative analyses as traditional Chinese medicine chemical reference products.The process has been proven to have good repeatability and scalability,and it features a concise preparation procedure,efficient purification,and high yield and purity,requiring no chromatographic separation.Compared with pre-vious methods,the newly developed process has significant advantages and is suitable for the preparation of chemical reference products of aristolactam Ⅰ-deoxyriboside adducts.This process provides technical support for the preparation of reference products of aristolac-tam Ⅰ-deoxyriboside adducts and a solid material basis for the related toxicological research.
