Galactofuranosylated Galactocerebrosides, a New Drug Delivery System for Ceramides to Colon
نویسندگان
چکیده
Two isomeric partially acetylated galactocerebrosides, ß-D-galactopyranosyl (2,3,4-tri-O-acetyl)and ß-Dgalactopyranosyl (2,4,6-tri-O-acetyl)-1’(3’-O-acetyl)ceramide, were prepared from galactocerebroside and sulfatide, respectively. Their galactofuranosylation produced ß-D-galactofuranosyl-6and ß-D-galactofuranosyl-3-ß-Dgalactopyranosyl-1’ceramide, as demonstrated by 1 H and 13 C NMR spectra as well as by chemical means.

In the long-term management of ulcerative colitis patients, repeat dosing maybe required. Since 5-ASA is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. The aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-ASA deliver...
