Enzymatic methods for glyco(diversification/randomization) of drugs and small molecules

Abstract

Glyco (randomization/diversification) is a term that encompasses strategies to diversify a core drug scaffold via enzymatic glycosylation to provide sets of analogs wherein the sole diversity element is a carbohydrate. This review covers the influence of glycosylation upon various drug properties, the classes of glycosyl-conjugating enzymes amenable to glyco(randomization/diversification) schemes, approaches to the synthesis of required substrates and specific examples of glycorandomized libraries utilizing both wild-type and engineered enzymes.
