Abstract:
:C-Mannosyl residue-containing trimannose ManC alpha(1,6)[Man alpha(1,3)Man] (2) and 5-thio-C mannosyl residue-containing trimannose 5SManC alpha(1,6)[Man alpha(1,3)Man] (3) were synthesized via a glycosyl radical addition to enone derivative of mannose (6). Dissociation constants for the binding of these trisaccharides to concanavalin A (ConA) were determined by a fluorescence anisotropy inhibition assay: Kd = 198 and 31 microM, respectively. The unexpectedly large Kd value for the compound 2 compared with the compound 3 and the natural trimannose 1 demonstrates a characteristic of C-glycoside.
