摘要:The present invention provides two synthetic routes for the preparation of Temsirolimus (compound 1b and analog of Temsirolimus 1a). The first route includes the synthesis of CCI-779 by directly reacting rapamycin (4b) or Prolyl-rapamycin (4a) with substituent-2,2-bis(methoxy) propionic acid anhydride(11) in the presence of an organic base, followed by deprotection to give CCI-779 or Proline CCI-779. The second route includes a process involving a reaction of rapamycin-OH-31-sily ether (4d) or Prolyl-rapamycin-OH-31-sily ether (4c) with substituent-2,2-bis(methoxy) propionic acid anhydride(11) in the presence of an organic base and followed by subsequent hydrolysis step to obtain the desired CCI-779 or Proline CCI-779. n Compound 11, as described in this invention, is stable at room temperature, cost effective and ease of processing.

权利人:ACADEMIA SINICA
摘要:The present disclosure relates to methods and compositions which can modulate the globoseries glycosphingolipid synthesis. Particularly, the present disclosure is directed to glycoenzyme inhibitor compound and compositions and methods of use thereof that can modulate the synthesis of globoseries glycosphingolipid SSEA-3/SSEA-4/GloboH in the biosynthetic pathway; particularly, the glycoenzyme inhibitors target the alpha-4GalT; beta-4GalNAcT-I; or beta-3GalT-V enzymes in the globoseries synthetic pathway. Additionally, the present disclosure is also directed to vaccines, antibodies, and/or immunogenic conjugate compositions targeting the SSEA-3/SSEA-4/GLOBO H associated epitopes (natural and modified) which elicit antibodies and/or binding fragment production useful for modulating the globoseries glycosphingolipid synthesis. Moreover, the present disclosure is also directed to the method of using the compositions described herein for the treatment or detection of hyperproliferative diseases and/or conditions. Furthermore, the instant disclosure also relates to cancer stem cell biomarkers for diagnostic and therapeutic uses.
