Preparation of two methyl deoxyfluoro-beta-D-galactopyranosides, and their interaction with galactan-specific immunoglobulin A J539 (Fab').

Methyl 2-deoxy-2-fluoro-beta-D-glactopyranoside (2) and methyl 4-deoxy-4-fluoro-beta-D-glactopyranoside (7) have been prepared, and the possibility of their binding to (1 leads to 6)-beta-D-galactopyranan-specific immunoglobulin A J539 (Fab') has been investigated. Compound 2 does not show binding, whereas 7 does. It appears that the 2-hydroxyl group of methyl beta-D-galactopyranoside may take part in hydrogen bonding to the protein.

Specificity of α- and β-D-galactosidase towards analogs of D-galactopyranosides modified at C-4 or C-5

In examining the stereochemistry of D-galactose oxidase, it was found that some 4-deoxy analogs of methyl β-D-galactopyranoside (1), particularly the 4-amino (2) and 4-fluoro (3) derivatives, are relatively good substrates of the enzyme.The same compounds
