我们已经设计并合成了一系列模块化双色染料,其中包括作为黄色发射体的常规硼二吡咯亚甲基(Bodipy)染料,以及具有扩展共轭功能的Bodipy染料,其作为红色发射体。由乙二醇残基构成的可变长度的柔性束线连接末端染料。这种类型的二元组的关键设计元素涉及介于常规Bodipy和系链之间的仲胺键。循环伏安法表明两种Bodipy染料均具有电活性,并表明仲胺非常容易被氧化。最好用快速形成中间电荷转移状态来解释随后的荧光猝灭。实际上,在弱极性溶剂和临界温度范围内观察到激基复合物型发射。-1。用较高能量的吸收剂(即pyr)代替红色发射器,有助于收集近紫外光,并将虚拟斯托克斯位移扩展到8000 cm -1。分子内能量转移功效的调节是通过在某些阳离子存在下对连接器进行预组织来实现的。后者的行为是完全可逆的,对应于人为的变构效应。
Disulfide bond formation is a critical post-translational modification of newly synthesized polypeptides in the oxidizing environment of the endoplasmic reticulum and is mediated by protein disulfide isomerase (PDIA1). In this study, we report a series of α-aminobenzylphenol analogues as potent PDI inhibitors. The lead compound, AS15, is a covalent nanomolar inhibitor of PDI, and the combination of
Glucose-sensing luminescent dyes, polymers, and sensors are provided. Additionally, systems including the sensors and methods of using these sensors and systems are provided.
