S-Nitroso-N-acetylpenicillamine (SNAP) is the chemical compound with the formula ONSC(CH₃)₂CH(NHAc)CO₂H. SNAP is an S-nitrosothiol and is used as a model for the general class of S-nitrosothiols which have received much attention in biochemistry because nitric oxide and some organic nitroso derivatives serve as signaling molecules in living systems, especially related to vasodilation.^[1] SNAP is derived from the amino acid penicillamine. S-Nitrosoglutathione is a related agent.
