The synthesis of amino-derivatives of castanospermine and australine and their characterisation as inhibitors of the exo-beta-D-glucosaminidase CsxA through enzyme kinetics and X-ray structural analysis is described.
The asymmetric total synthesis of the α-glucosidase inhibitor (+)-castanospermine is reported. The central theme in our approach to this polyhydroxylated alkaloid is the simultaneous generation of the piperidine ring and the C-1/8a erythro stereodiad through the diastereoselective, oxamidation of an
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
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.

sp(2)-Iminosugar-type castanospermine analogues bearing an alpha-configured N-, S-, or C-linked pseudoanomeric group have been designed as selective inhibitors of the neutral alpha-glucosidases involved in N-glycoprotein processing; evaluation in breast cancer cell growth indicated a significant antiproliferative potential that was dependent
