Abstract: The present invention relates to a process for the preparation and manufacture of 3-amino-substituted glycosylated bile acid derivatives. Novel intermediates and related compounds are also disclosed. In particular, the present invention permits the conversion of cholic acid esters to the 3-amino-7,12-bis(glucosyl)cholic acid esters via an azide intermediate. Conditions for the purification and isolation of the desired product is also disclosed to provide an overall manufacturing process suitable for large-scale production.

Abstract: Novel glycosylated steroid derivatives for facilitating the transport of compounds across biological membranes, either in admixture or as conjugates, are disclosed. A novel process for efficient synthesis of these glycosylated steroid derivatives, using activated glycosyl sulfoxide intermediates is provided. Methods for the permeabilization of membranes and the enhancement of the activity of predetermined compounds are also provided.
