Saccharide derivatives are represented by the general formula [I]
wherein R1 represents a residual group formed by removing the hemiacetal hydroxyl group from a monosaccharide, disaccharide or trisaccharide, R2 represents
-CONH2 or -CH2COOR3 and R3 represents a hydrogen atom, an alkyl of one to four carbon atoms or an equivalent of pharmaceutically acceptable metal. These derivatives can be used either alone or in the form of compositions with a pharmaceutically acceptable carrier or diluent to reduce blood sugar levels and blood pressure.
