Bicyclic 1-Azafagomine Derivatives: Synthesis and Glycosidase Inhibitory Testing

The synthesis of a series of 1-azafagomine derivatives that are tethered with five- and six-membered 1,2-annulated ring systems is described. These compounds were used in order to explore whether a hydrogen-bond acceptor group on the carbon atom corresponding to the glycosidic oxygen is able to interact with the catalytic acidic residue of β-glucosidase. The hydrogen-bond acceptor group was installed at various positions on the annulated ring system making it possible to study the effect of altering the position of this group.

Synthesis and evaluation of: N -alkylated analogues of aza-galacto-fagomine-potential pharmacological chaperones for Krabbe disease

Seven novel alkylated or acylated analogues of hexahydropyridazine aza-galacto-fagomine (AGF) was prepared and studied as glycosidase inhibitors with the aim of increasing inhibitory potency and selectivity. The enzyme galactocerebrosidase, implicated in Krabbe disease, was found to be potently inhibited by n-butyl N2-alkylated AGF.

Azasugar inhibitors as pharmacological chaperones for Krabbe disease

Krabbe disease is a devastating neurodegenerative disorder characterized by rapid demyelination of nerve fibers. This disease is caused by defects in the lysosomal enzyme β-galactocerebrosidase (GALC), which hydrolyzes the terminal galactose from glycosphingolipids. These lipids are essential components of eukaryotic cell membranes: substrates of GALC include galactocerebroside, the primary lipid component of myelin, and psychosine, a cytotoxic metabolite. Mutations of GALC that cause misfolding of the protein may be responsive to pharmacological chaperone therapy (PCT), whereby small molecules are used to stabilize these mutant proteins, thus correcting trafficking defects and increasing residual catabolic activity in cells. Here we describe a new approach for the synthesis of galacto-configured azasugars and the characterization of their interaction with GALC using biophysical, biochemical and crystallographic methods. We identify that the global stabilization of GALC conferred by azasugar derivatives, measured by fluorescence-based thermal shift assays, is directly related to their binding affinity, measured by enzyme inhibition. X-ray crystal structures of these molecules bound in the GALC active site reveal which residues participate in stabilizing interactions, show how potency is achieved and illustrate the penalties of aza/iminosugar ring distortion. The structure-activity relationships described here identify the key physical properties required of pharmacological chaperones for Krabbe disease and highlight the potential of azasugars as stabilizing agents for future enzyme replacement therapies. This work lays the foundation for new drug-based treatments of Krabbe disease.

Iodine monochloride (ICl) was discovered to be a highly efficient, green oxidant, which can oxidize aldose hemiacetals, diarylmethanols, arylalkylmethanols, anddialkylmethanols to the corresponding aldose lactones, diarylmethanones, arylalkylmethanones, and dialkylmethanones, respectively, in high yields. ICl as a green, metal-free oxidant is characterized by mild reaction condition, short reaction time, good yield, and broad scope.

Chiral pyrroline-based Ugi-three-component reactions are under kinetic control

Although it is often assumed that the stereochemistry in Ugi multicomponent reactions is determined in the final Mumm rearrangement step, experimental and computational evidence that Ugi reactions on hydroxylated pyrrolines proceed under kinetic control is reported. The stereochemistry of the reaction is established with the addition of the isocyanide to the intermediate iminium ion, whose conformation is determined by its substitution pattern.
