S-nitrosothiols

特許 権利維持 S-Nitrosothiols, also known as thionitrites, are organic compounds or functional groups containing a nitroso group attached to the sulfur atom of a thiol.[1] S-Nitrosothiols have the general formula RSNO, where R denotes an organic group. S-Nitrosothiols have received much attention in biochemistry because they serve as donors of the nitrosonium ion NO+, and nitric oxide and some organic nitroso derivatives serve as signaling molecules in living systems, especially related to vasodilation.[2] Red blood cells, for instance, release S-nitrosothiols into the bloodstream under low-oxygen conditions, causing the blood vessels to dilate.
