The glycoprotein processing inhibitor castanospermine (CS) and the monosaccharide mannose-6-phosphate (M6P), as well as some sulfated polysaccharides (SPS), have been shown to inhibit inflammation in rat models of experimental autoimmune encephalomyelitis and adjuvant-induced arthritis. Here, the anti-inflammatory effects of these
Saccharide primers, such as dodecyl beta-lactoside (Lac-C12), are unique artificial precursors of glycolipid synthesis. In culture media supplemented with saccharide primers, they are taken up by the cells in the culture media and glycosylated by cellular glycosyltransferases in the Golgi
Synthesis of a panel of iso(thio)urea-type ring-modified castanospermine analogues bearing a freely mutarotating pseudoanomeric hydroxyl group results in tight-binding beta-glucosidase inhibitors with unusual binding signatures; the presence of an N-octyl substituent imparts a remarkable anomeric selectivity, promoting strong binding of

A nine-step synthesis of (+)-castanospermine has been accomplished in 22% overall yield from methyl alpha-D-glucopyranoside. The key transformations involve a zinc-mediated fragmentation of benzyl-protected methyl 6-iodoglucopyranoside, ring-closing olefin metathesis, and strain-release transannular cyclization to afford the indolizidine skeleton of the
An asymmetric synthesis of (+)-castanospermine is presented in which enol ether metathesis-hydroboration/oxidation is used for stereoselective installation of the trans-trans hydroxyl groups on the piperidine ring of the alkaloid.
