摘要: Sugar-modified SIN-1 compositions are provided. The compositions are useful for generating NO in response to hydrolytic activity of a glycosidase specific for the O-glycosidic bond between the sugar and SIN-1 moieties. Pharmaceutical compositions containing the sugar-modified SIN-1 compositions and methods of using the compositions are also provided.
