Methyl oligobiosaminide (1) the core structure of oligostatin C, and five analogues, the 6-hydroxy-(2), 2-deoxy- (3), 2-deoxy-6-hydroxy- (4), 3-deoxy- (5), and 3-deoxy-6-hydroxy derivatives (6), were synthesized by coupling the protected pseudo-sugar epoxide 46 with suitable methyl 4-amino-4-deoxy-alpha-D-hexopyranoside derivatives. Compounds 3 and 6 showed notable inhibitory activity against alpha-D-glucosidase and alpha-D-mannosidase, respectively, whereas compound 1 had almost no activity.
2-Substituted methyl alpha-D-galactopyranosides: synthesis and binding affinity for the A and B subunits of the Griffonia simplicifolia I isolectins.

The binding affinities of the N-acetyl, N-trifluoroacetyl, N-propionyl, N-formyl, N-benzoyl, N-p-nitrobenzoyl, N-p-aminobenzoyl, and N-methyl derivatives of methyl 2-amino-2-deoxy-alpha-D-galactopyranoside and the 2-O-acetyl, -benzoyl, -benzyl, and -methyl derivatives of methyl alpha-D-galactopyranoside for the A and B subunits of the Griffonia simplicifolia I isolectins have been determined by hapten inhibition analysis of a galactomannan-isolectin precipitation system. Models for these carbohydrate-protein interactions are presented together with an interpretation of the results on the basis of electronic and steric effects.
