Glycosaminoglycan (GAG) side chains of proteoglycans are involved in a wide variety of developmental and pathophysiological functions. Similar to a gene knockout, the ability to inhibit GAG biosynthesis would allow us to examine the function of endogenous GAG chains. However, ubiquitously and irreversibly knocking out all GAG biosynthesis would cause multiple effects, making it difficult to attribute a specific biological role to a specific GAG structure in spatiotemporal manner. Reversible and selective inhibition of GAG biosynthesis would allow us to examine the importance of endogenous GAGs to specific cellular, tissue, or organ systems. In this chapter, we describe the chemical synthesis and biological evaluation of xyloside derivatives as selective inhibitors of heparan sulfate and chondroitin/dermatan sulfate proteoglycan biosynthesis.
Keywords: Chondroitin sulfate; Dermatan sulfate; Glycosaminoglycan biosynthesis; Heparan sulfate; Proteoglycan inhibitor; Xyloside derivative.
