Abstract:
:Selective monofluorination of the alpha-glycosidase inhibitor and antidiabetic agent Miglitol at position C2 creates an competitive inhibitor of five times higher activity than the parent compound. Its screening against a panel of human cell lines showed a low cytotoxicity therefore making this compound an interesting candidate for further clinical investigations.
