| + | A new approach for the discovery and subsequent structural elucidation of oligosaccharide-based inhibitors of alpha-amylases based upon autoglucosylation of known alpha-glucosidase inhibitors is presented. This concept, highly analogous to what is hypothesized to occur with acarbose, is demonstrated with the known alpha-glucosidase inhibitor, d-gluconohydroximino-1,5-lactam. This was transformed from an inhibitor of human pancreatic alpha-amylase with a K(i) value of 18 mm to a trisaccharide analogue with a K(i) value of 25 mum. The three-dimensional structure of this complex was determined by x-ray crystallography and represents the first such structure determined with this class of inhibitors in any alpha-glycosidase. This approach to the discovery and structural analysis of amylase inhibitors should be generally applicable to other endoglucosidases and readily adaptable to a high throughput format. | ||
