Abstract

The present invention provides methods of producing libraries of compounds with enhanced desirable properties and diminished side effects as well as the compounds produced by the methods. In preferred embodiments, methods of the present invention use a universal chemical glycosylation method that employs reducing sugars and requires no protection or activation. In a preferred embodiment, the invention provides a library of neoglycoside digitoxin analogs that includes compounds with significantly enhanced cytotoxic potency toward human cancer cells and tumor-specificity, but are less potent Na/K-ATPase inhibitors in a human cell line than digitoxin.
