• Microwave-assisted synthesis of N-glycolylneuraminic acid derivatives

  A rapid, efficient and scalable synthesis of biologically-relevant N-glycolylneuraminic acid derivatives from the natural N-acetyl (Neu5Ac) precursors has been developed. Microwave irradiation provides accelerated de-N-acetylation compared to more traditional methods, with optimised NaOH-promoted de-N-acetylation in only 15 min. The prepared amines were readily re-N-acylated to afford the corresponding N-glycolyl (Neu5Gc) analogues. (C) 2013 Elsevier Ltd. All rights reserved.

  A molecular modelling study using the program GRID has been used to investigate the structural requirements of a potential inhibitor binding to Vibrio cholerae sialidase. A number of favourable interactions were predicted between the sialidase and Neu2en derivatives containing hydroxyl- or halogen-substituted acyl groups on the C-5 amine. As a result of this study, a detailed analysis of the interactions of C-5-substituted Neu2en derivatives with the active site of V. cholerae sialidase was undertaken using a conformational searching routine based on molecular dynamics. Based on the results of these molecular design studies several N-acyl-Neu2en-based probes were prepared and evaluated for sialidase inhibition. As envisaged, and pleasingly, the designed compounds were found to be accommodated by the enzyme's active site architecture, and to be strong inhibitors of V. cholerae sialidase.
