- Abstract
Gangliosides, glycosphingolipids containing one or more sialic acids in the glycan chain, are involved in various important biological processes in cell plasma membranes (PMs). However, the behaviors and functions of gangliosides are poorly understood, primarily because of the lack of fluorescent analogs that are equivalent to native gangliosides that can be used as chemical and physical probes. In this study, we developed entirely chemical methods to synthesize fluorescent gangliosides (GM3, GM2, GM1, and GD1b) in which the glycan components are site-specifically labeled with various fluorescent dyes. The functional evaluations of the synthesized fluorescent gangliosides demonstrated the great influence of fluorescent dye on the physical properties of gangliosides in PMs and revealed the fluorescent ganglioside analogs which show similar behaviors to the native gangliosides., (© 2017 Elsevier Inc.
