Conformationally-locked N -glycosides with selective β-glucosidase inhibitory activity: Identification of a new non-iminosugar-type pharmacological chaperone for gaucher disease

A series of conformationally locked N-glycosides having a cis-1,2-fused pyranose-1,3-oxazoline-2-thione structure and bearing different substituents at the exocyclic sulfur has been prepared. The polyhydroxylated bicyclic system was built in only three steps by treatment of the corresponding readily available 1,2-anhydrosugar with KSCN using TiO(TFA)2 as catalyst, followed by S-alkylation and acetyl deprotection. In vitro screening against several glycosidase enzymes showed highly specific inhibition of mammalian β-glucosidase with a marked dependence of the potency upon the nature of the exocyclic substituent. The most potent representative, bearing an S-(ω-hydroxyhexadecyl) substituent, was further assayed as inhibitor of the human lysosomal β-glucocerebrosidase and as pharmacological chaperone in Gaucher disease fibroblasts. Activity enhancements in N370S/N370S mutants analogous to those achieved with the reference compound ambroxol were attained with a more favorable chaperone/inhibitor balance.

Simple and efficient synthesis of O-unprotected glycosyl thiourea and isourea derivatives from glycosylamines

Practical, facile and high-yielding one-pot syntheses of different O-unprotected glycopyranosyl thioureas and thioureido bolaamphiphiles (two-step synthesis) and of 2-amino-4,5-dihydro-(1,2-dideoxy-β-D-glucopyranoso)[1,2- d]oxazoles (three-step synthesis) from glycopyranosylamines are reported. The method involves the preparation of O-unprotected β-D-gluco (and D-galacto)pyranosyl isothiocyanates which are in equilibrium with the corresponding 1,2-cyclic thiocarbamates, coupling with amines to afford glycosyl thioureas and treatment with yellow mercury (II) oxide to give trans-fused bicyclic isoureas. A D-gluco trehazolin analogue is prepared in this way. In situ transformation of N,N-dialkyl, N′-glucopyranosyl thioureas into the corresponding ureas is also reported.
