  respect to both isomers. More importantly, irreversible reduction of the azo group to the corresponding hydrazine was observed. Independent experiments revealed that reducing agents such as DTT (dithiothreitol) and GSH (glutathione) that are typically used for protein stabilization in biological assays were responsible. Two further sources of error are the concentration dependence of the E–Z-switching efficiency

  在光药理学中，包括偶氮苯或其他二芳基偶氮基部分的可光转换化合物通常在细长的E-构型中表现出针对靶蛋白的生物活性，而相当大的Z-构型在药理学上通常效力较低。在本文中，我们报道了针对p38αMAPK和CK1δ的新型光开关激酶抑制剂的设计，合成和光化学/抑制特性。使用表征良好的抑制剂支架来连接芳基偶氮和重氮部分。当分离的异构体或异构体的光平稳状态（PSS）在常用体外进行测试时然而，在激酶测定中，仅观察到活性的微小差异。配体结合的p38αMAPK和CK1δ复合物的X射线分析表明，该蛋白相对于两种异构体具有动态构象适应性。更重要的是，观察到偶氮基不可逆地还原为相应的肼。独立实验表明，还原剂（例如DTT（二硫苏糖醇）和GSH（谷胱甘肽））通常在生物学分析中用于蛋白质稳定化。误差的另外两个来源是E – Z转换效率的浓度依赖性以及在测试过程中由于不完全排除光而导致的伪影。我们的发现也可能适用于许多以前研究过的基于偶氮苯的可光转换抑制剂。
