  Synthesis and glycosidase inhibitory activity of some N-substituted 5a-carba-β-fuco- and β-galactopyranosylamines, and selected derivatives

  摘要：

  In the course of chemical modification of alpha-fucosidase inhibitors of 5a-carba-fucopyranosylamine type, an N-dodecyl derivative of the enantiomer 6-deoxy-5a-carba-beta-(D)-galactopyranosylamitie demonstrated very strong inhibition of beta-galactosidase and beta-glucosidase. This finding led us to synthesize corresponding 6-hydroxy compounds, in order to elucidate structure-activity relationships for inhibitors of this type. Among four N-alkyl-5a-carba-beta-(D)-galactopyranosylatnines prepared, the N-octyl derivative could be demonstrated to possess moderate activity toward alpha- and beta-galactosidases, and beta-glucosidase.

  This minireview covers synthetic methods towards carbasugar-containing non-glycosidically linked pseudodisaccharides or higher pseudooligosaccharides. Carbocyclic pyranose mimetics (saturated or unsaturated between C-5 and C-5a) are linked by ether, thioether or amine bridges to carbohydrates or other carbasugars.
