of sixteen naturalproduct‐inspired polyhydroylated pyrrolidine‐based isomeric scaffolds is described. Each scaffold possesses four stereogenic centers and one exo‐aminomethyl moiety, which allows for rapid substituent diversity. To exemplify biological applications, these new privileged scaffolds were used to discover newhumanGolgiα‐mannosidaseIIinhibitors. The most potent inhibitor shows competitive

iminocyclitol-based smallmoleculelibraries against a bacterial TGase is described. An iminocyclitol was conjugated with a pyrophosphate mimic using either a 1,3-dipolar cycloaddition or reductive amination reaction, which was then condensed with a variety of lipophilic carboxylic acids in an amide bond coupling to generate a desired molecularlibrary. With assistance of microtiter plate-based combinatorial chemistry

New methodology for the preparation of a variety of aminoiminohextitols is described. Key in the synthesis is the application of a diastereoselective Strecker reaction and the extension of our carbamateannulationmethodology to protected and functionalized alkenylamines. Insight into the effects that the substitution patterns of the alkenylamines have on the diastereoselectivity of the iodocyclization
Disclosed herein are novel uses of a polyhydroxylated pyrrolidine for the manufacture of a medicament for treating Fabry disease (FD). Accordingly, the present disclosure provides a method of treating a subject having or suspected of having FD. The method includes the step of, administering to the subject a therapeutically effective amount of a compound of formula (I), a salt, an ester or a solvate thereof, wherein: R1 is H, or C1-3 amine optionally substituted with —COR2; R2 is alkyl or alkene optionally substituted with cycloalkyl or phenyl having at least one substituent selected from the group consisting of, halo, alkyl, haloalkyl, and alkoxyl; so as to ameliorate, alleviate mitigate and/or prevent symptoms associated with the FD. According to preferred embodiments of the present disclosure, the compound of formula (I) is a chaperon of a mutated human lysosomal α-galactosidase A (α-Gal A).

Novel derivatives of the D-glucosidase inhibitor 2,5-dideoxy-2,5-imino-D-mannitol bearing lipophilic aliphatic or aromatic amides attached to C-l have been found to inhibit P-glucosidase from Agrobacterium sp. in the nanomolar range. One of them, a coumarin derivative. ranks amongst the most active compounds in the class of reversible glycosidase inhibitors of the iminoalditol type. (C) 2001 Elsevier Science Ltd.
