  The invention provides amphiphilic compounds with hydrophobic and hydrophilic faces. The compounds can be readily prepared from steroids such as cholic acid or deoxycholic acid, which provide hydrophobic skeletons with structures similar to that of the lipid cholesterol. The compounds of the invention can be used to aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins, and to prepare micelles for delivery of a bioactive agent, such as a drug or a gene, to a subject.

  该发明提供了具有疏水和亲水面的两性化合物。这些化合物可以从类固醇如胆酸或去氧胆酸中轻松制备，这些类固醇提供了与脂质胆固醇类似的具有疏水骨架的结构。该发明的化合物可用于辅助溶解、分离、纯化、稳定化、结晶和/或确定膜蛋白的结构，并制备微胶束以传递生物活性剂，如药物或基因，给受试者。
• 1,2,3-Triazoles and related glycoconjugates as new glycosidase inhibitors

  A series of saccharidyl-triazoles structurally related to acarbose were prepared and tested as inhibitors of glycosidases. They share in common a 1,4,5trisubstituted 1,2,3-triazole heterocycle as a functional element able to interact with the active site of the target enzymes. First, it was established that the heterocyclic core exhibits a moderate but highly selective a-glucosidase inhibitory activity. Then, it was confirmed that the inhibitory properties could be modulated by conjugation from one to five carbohydrate residues. The present study includes the regio- and stereocontrolled synthesis of novel non-fused 1,2,3-triazolo-pseudooligosaccharides as well as their evaluation as new glycosidase inhibitors.

• Unexpected fluorous solvent effect on oxidation of 1-thioglycosides

  Oxidation of various 1-thioglycopyrano- and furanosides with H2O2/Ac2O/SiO2 was performed in CH2Cl2/aprotic perfluorinated solvent mixtures (100:0 to 1:19, v/v). Reactions appeared much faster at a solvent ratio of 1:1 without significant over-oxidation to sulfones and modification of diastereoselectivity. Nevertheless, the nature of both the glycosyl moiety and the protecting group influenced the (S-S):(R-S) product ratio. (C) 2001 Published by Elsevier Science Ltd.
