Publication number: 20200200758Abstract: 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.Type: ApplicationFiled: November 27, 2019Publication date: June 25, 2020Inventors: Chi-Huey WONG, Chung-Yi WU, Sarah K.C. CHEUNG, Po-Kai CHUANG, Tsui-Ling HSU
