An examination of some derivatives of S-nitroso-1-thiosugars as vasodilators

A number of S-nitrosated compounds derived from l-thiosugars (glucose, galactose, xylose, maltose, and lactose) have been prepared and characterized, Most of the compounds obtained were unstable either as solids or in solution. However, S-nitroso-1-thio-2,3,4,6-tetra-O-acetylglucopyranose was stable enough to examine as a vasodilator using an isolated rat tail artery model. It also proved effective in human cutaneous vascular smooth muscle relaxation when delivered transdermally. (C) 1997 Academic Press.
