  Synthetic Studies of Complex Immunostimulants from Quillaja saponaria:  Synthesis of the Potent Clinical Immunoadjuvant QS-21A_api

  摘要：

  QS-21 is one of the most promising new adjuvants for immune response potentiation and dose-sparing in vaccine therapy given its exceedingly high level of potency and its favorable toxicity profile. Melanoma, breast cancer, small cell lung cancer, prostate cancer, HIV-1, and malaria are among the numerous maladies targeted in more than 80 recent and ongoing vaccine therapy clinical trials involving QS-21 as a critical adjuvant component for immune response augmentation. QS-21 is a natural product immunostimulatory adjuvant, eliciting both T-cell- and antibody-mediated immune responses with microgram doses. Herein is reported the synthesis of QS-21A(api) in a highly modular strategy, applying novel glycosylation methodologies to a convergent construction of the potent saponin immunostimulant. The chemical synthesis of QS-21 offers unique opportunities to probe its mode of biological action through the preparation of otherwise unattainable nonnatural saponin analogues.

  C-glycosides via BF3·Et2O promoted coupling of organotrifluoroborates and glycosyl fluorides is reported. The application of this method was further demonstrated by the concise and efficient total synthesis of (+)-varitriol in only seven steps.

  据报道，通过BF 3 ·Et 2 O促进了有机三氟硼酸酯和糖基氟化物的偶联，采用了温和，立体选择性和快速的方法访问炔基和烯基C-糖苷。该方法的应用通过仅七个步骤的简明有效的全合成（+）-varitriol进一步得到了证明。

  Provided are variants of saponins that are found in Quillaja saponaria (QS) Molina tree bark that are chemically modified to distinguish them from naturally occurring parent saponins. The modified saponins have increased adjunctive activity compared to the unmodified parent saponins. Defined structures allow for comparisons of the modifying groups with respect to their respective adjunct activity and permit characterized vaccine formulations that have one or more defined saponins.

  提供了在Quillaja saponaria (QS) Molina树皮中发现的皂苷的变种，这些皂苷经过化学修饰，以使它们与自然存在的原始皂苷有所区别。经过修改的皂苷与未经修改的原始皂苷相比具有增强的辅助活性。定义的结构允许对修饰基团进行比较，以确定它们各自的辅助活性，并允许确定具有一个或多个定义的皂苷的疫苗配方。

  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.

  本发明涉及三萜糖苷皂苷衍生的佐剂、其合成、中间体及其用途。QS-7是一种强效的免疫佐剂，其毒性显著低于QS-21，QS-21是目前在抗癌和抗病毒疫苗中被广泛使用的相关皂苷佐剂。繁琐的分离和纯化方案阻碍了QS-7的临床开发。本发明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和相关的类似物，极大地促进了QS-7和QS-21类似物的临床前和临床评估。
