Cell surface carbohydrates play significant roles in a number of biologically importantprocesses. Heparan sulfate (HS), for instance, is a ubiquitously distributed polysulfatedpolysaccharide that is involved, among others, in the initial step of herpes simplex virus type1 (HSV-1) infection. The virus interacts with cell surface HS to facilitate host cellattachment and entry. 3-O-Sulfonated HS was discovered to function as an HSV-1 entryreceptor. A complete understanding of these interactions necessitates the chemical synthesisof such oligosaccharides, but remains challenging. Here, we present a convenient approachfor the synthesis of two irregular 3-O-sulfonated HS octasaccharides making use of a keydisaccharide intermediate to acquire different building blocks for the oligosaccharide chainassembly. Despite substantial structural differences, the prepared 3-O-sulfonated sugarsblocked viral infection in a dosage-dependent manner with remarkable similarity.
