To achieve site specific delivery of nitric oxide (NO), a new class of glycosidase activated NO donors has been developed. Glucose, galactose, and N-acetylneuraminic acid were covalently coupled to 3-morphorlinosydnonimine (SIN-1), a mesoionic heterocyclic NO donor, via a carbamate linkage at the anomeric position. The beta-glycosides were successfully prepared for these conjugates, while the alpha-glycosidic compounds were very unstable. The new stable sugar-NO conjugates could release NO in the presence of glycosidases. Such NO prodrugs may be used as enzyme activated NO donors in biomedical research.
