Several families of iminosugar‐based galactosidemimics were designed, synthesized, and evaluated as galactocerebrosidase (GALC) inhibitors. They were also tested as inhibitors of lysosomal β‐ and α‐galactosidases in order to find new potent and selective pharmacological chaperones for treatment of the lysosomal storage disorder, Krabbe disease. Whereas 1‐C‐alkyl imino‐L‐arabinitols are totally inactive
Synthesis of (±)-isofagomine and its stereoisomers from arecoline

(±)-Isofagomine (1) and all its stereoisomers were prepared in a short synthesis from arecoline. The double bond of arecoline was isomerised to be no longer conjugated to the carboxy, and the ester reduced to (hydroxymethyl)tetrahydropyridine 5 which after dihydroxylation of the alkene, separation and N-demethylation gave 1 and its isomers.

A new route for the synthesis of isofagomine analogues has been carried out by using as precursorsenantiopure 5-trihydroxypropyl-dihydrouracil derivatives obtained from aldol-type addition of 1,3-dibenzyl-dihydrouracil to isopropylidene-protected glyceraldehyde. The synthesis of d-galacto-isofagomine is reported.

In order to provide a parasitic plant control agent and a parasitic plant control method each of which is capable of controlling a parasitic plant effectively, a parasitic plant is controlled by inhibiting gentianose metabolism in the parasitic plant so as to inhibit germination of the parasitic plant.
