The present invention relates to a new class of sialyltransferase inhibitors. The class features a carbamate or similar moiety on the amine of a neuraminic acid derivative. Such inhibitors are suitable for use as a medicament, for example for treating, preventing, or delaying bacterial infection, viral infection, cancer, a disorder of sialic acid metabolism, or an autoimmune disease.
