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 R
3
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.
具有以下公式的可用作生物相关介质中还原剂的取代二硫代吡嗪化合物:
其中变量在此定义,对应的氧化的吡嗪二硫代环。
还原剂可用于还原二硫键,特别是在蛋白质中,或者防止二硫键的形成,特别是在蛋白质和其他生物分子中。还原剂可用于调节与生物活性相关的巯基团的蛋白质功能。还原剂可用于各种生物应用,特别是作为研究和合成试剂。S-酰化的二硫代吡嗪化合物,其中R3是酰基,通过酶或化学方法去除S-酰基团而被选择性激活为还原剂。提供了固定在表面上或与其他化学物种结合的二硫代吡嗪还原剂和相应的S-酰化的二硫代吡嗪。
