No anthelmintic sugars have yet been identified. Eight ketohexose stereoisomers (d- and l-forms of psicose, fructose, tagatose and sorbose), along with d-galactose and d-glucose, were examined for potency against L1 stage Caenorhabditis elegans fed Escherichia coli. Of the sugars, d-psicose specifically inhibited the motility, growth and reproductive maturity of the L1 stage. d-Psicose probably interferes with the nematode nutrition. The present results suggest that d-psicose, one of the rare sugars, is a potential anthelmintic.
