[GRAPHICS]The use of carbohydrate sulfonyl chlorides is introduced as a new, facile glycoconjugation method which could find broad applications. We demonstrate the approach by synthesizing a number of glycosylated cholesterol absorption inhibitors which display high inhibitory efficacies in our recently established in vitro assay. Furthermore, we highlight an advantage of the electron-withdrawing nature of the suffonyl linkage which allowed the synthesis of otherwise unstable azetidine conjugates.

We have utilized our recently developed in vitroassay to address two key questions in the design of small-moleculecholesterolabsorptioninhibitors using ezetimibe, the only drug yet approved for the inhibition of cholesterolabsorption in the small intestine, as a starting point: (1) the role of glycosylation and (2) the importance of the beta-lactam scaffold of ezetimibe for inhibitory activity
