We have reported that the rare sugar, D-arabinose (D-Ara), a stereoisomer of D-ribose, inhibits the growth of the nematode Caenorhabditis elegans. However, the underlying mechanism of action is unclear. D-Ara is presumed to be phosphorylated by sugar kinases to yield D-Ara-5-phosphate (D-Ara-5P), which inhibits enzymes involved in sugar metabolism. We focused on two enzymes as targets for D-Ara-5P, i.e. glucose phosphate isomerase (GPI) in glycolysis, and ribose phosphate isomerase (RPI) in the pentose phosphate pathway. D-Ara-5P showed inhibitory activities against both C. elegans enzymes, which may account for the D-Ara-mediated growth inhibition.
