摘要:

阿卡波糖是一种α-葡萄糖苷酶抑制剂,凭借其独特的作用机制,目前已被广泛应用于2型糖尿病的治疗中.本文利用DEPT-135、1H-1H COSY、1H-13C HSQC和1H-13C HMBC等一维、二维核磁共振(NMR)技术,首次报道了阿卡波糖在DMSO-d6中的1H NMR和13C NMR数据、阿卡波糖所有羟基的氢谱数据和C环α、β双信号氢谱和碳谱数据,并对其1H NMR、13C NMR信号进行了全归属,确证了其分子结构,为阿卡波糖药品安全及质量控制提供了可靠的数据基础.

Abstract:

Acarbose, an α - glucosidase inhibitor, has been widely used in the treatment of type-II diabetes due to its unique mechanism of action. Acarbose’s comprehensive and accurate 1H-NMR and 13C-NMR data,as well as 1H-NMR data of all hydroxyl groups of acarbose and 1H-NMR and 13C-NMR data of the dual signal of C-ring α and β, were reported in DMSO-d6 for the first time. The attribution of 1H NMR and 13C NMR data were carried out by using DEPT-135, 1H-1H COSY, 1H-13C HSQC, and 1H-13C HMBC techniques. The molecular structure of Acarbose was confirmed, which provided a reliable data foundation for the safety and quality control of Acarbose drugs.
