    摘要: Substituted dithiol pyrazine compounds useful as reducing agents in biologically relevant media having formula: where variables are defined herein and corresponding oxidized pyrazine dithianes. Reducing agents useful to reduce disulfide bonds, particularly in proteins, or to prevent the formation of disulfide bonds, particularly in proteins, and other biological molecules. Reducing agents useful to regulate protein function in proteins in which a sulfhydryl group is associated with biological activity. Reducing agents useful and suitable for application in a variety of biological applications, particularly as research and synthetic reagents. S-acylated dithiol pyrazine compounds, where R3 is an acyl group, are selectively activated as reducing agents by removal of the S-acyl groups enzymatically or chemically. Dithiol pyrazine reducing agents and corresponding S-acylated dithiol pyrazines, immobilized on surfaces or conjugated to other chemical species, are provided.
