    Abstract: Modified Fc regions of antibodies and antibody fragments, both human and humanized, and having enhanced stability and efficacy, are provided. Fc regions with core fucose residues removed, and attached to oligosaccharides comprising terminal sialyl residues, are provided. Antibodies comprising homogeneous glycosylation of Fc regions with specific oligosaccharides are provided. Fc regions conjugated with homogeneous glycoforms of monosaccharides and trisaccharides, are provided. Methods of preparing human antibodies with modified Fc using glycan engineering, are provided.

    Abstract: The present disclosure is directed to vaccines, antibodies, and/or immunogenic conjugate compositions targeting the SSEA3/SSEA4/GloboH associated epitopes (natural and modified) which elicit antibodies and/or binding fragment production useful for modulating the globo-series glycosphingolipid synthesis. The present disclosure relates to methods and compositions which can modulate the globo-series 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 globo-series glycosphingolipid SSEA3/SSEA4/GloboH in the biosynthetic pathway; particularly, the glycoenzyme inhibitors target the alpha-4GalT; beta-4GalNAcT-I; or beta-3GalT-V enzymes in the globo-series synthetic pathway. 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.
