Cyclic D- and L-4-aminothreose were synthesised from ethyl D- and L-tartrate, respectively. D-aminothreose was a potent inhibitor of alpha-glucosidase and of alpha-mannosidase. From the glycosidase inhibition potencies of the four 4-amino-4-deoxy-tetroses, the contribution of binding of each functionality of the 5 and 6 membered ring amino-sugars towards the various glycosidases is discussed.

A novel modulator of sodium ion currents was synthesized in 6 steps from a protected dihydroxypyrrolidine nitrone, via 1,3-dipolar cycloaddition reaction with acrylamide. Sodium ion currents in 850 cells were evaluated in comparison to saxitoxin and tetrodotoxin and revealed an IC50 of 15.7 mu M. The new compound shows no evidence of binding to the C-lobe of the saxitoxin-binding protein saxiphilin.
