The present invention relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, intermediates thereto, and uses thereof. QS-7 is a potent immuno-adjuvant that is significantly less toxic than QS-21, a related saponin that is currently the favored adjuvant in anticancer and antiviral vaccines. Tedious isolation and purification protocols have hindered the clinical development of QS-7. A novel semi-synthetic method is provided wherein a hydrolyzed prosapogenin mixture is used to synthesize QS-7, QS-21, and related analogs, greatly facilitating access to QS-7 and QS-21 analogs for preclinical and clinical evaluation.
本发明涉及以三萜甙苷皂苷为基础的佐剂,其合成,中间体以及使用方法。 QS-7是一种强效的免疫佐剂,其毒性明显低于QS-21,QS-21是当前抗癌和抗病毒疫苗中受欢迎的佐剂。繁琐的分离和纯化协议阻碍了QS-7的临床开发。提供了一种新的半合成方法,其中使用水解的原皂苷混合物来合成QS-7,QS-21和相关类似物,极大地促进了QS-7和QS-21类似物的临床前和临床评估。
