蛋白质过硫化是一种新定义的氧化翻译后修饰,在许多生物学过程中都起着重要作用。迫切需要检测生命系统中的蛋白质过硫化,以促进H 2 S / H 2 S n的研究。基于信号的和细胞氧化还原调节。在这里,我们开发了一种新颖的离线荧光探针,用于在生物系统中使用化学传感器HQO-SSH检测过硫化。HQO-SSH具有反应速度快,选择性好,灵敏度高的特点。由于HQO-SSH的独特功能,该探针已成功应用于肺细胞中图像蛋白质的过硫化变化。我们还证明了该探针适用于肺组织中蛋白质过硫化的成像。此外,用这种方法的共聚焦成像表明,硫芥子油(一种常用的化学战剂)减少了活肺细胞和组织中线粒体蛋白质的过硫化作用。由于这些结果,该探针对于探索蛋白质过硫化在各种病理生理条件下的作用具有广阔的前景。

target in AML treatment. Here, we designed and developed an antibody drug conjugate (CD123-CPT) by integrating anti-CD123 antibody with a chemotherapeutic agent, Camptothecin (CPT), via a disulfide linker. The linker is biodegradable in the presence of Glutathione (GSH, an endogenous component in cells), which leads to release of CPT. Anti-CD123 antibody conjugates showed significant higher cellular

Described herein are compounds that may selectively bind to Hsp90, methods of using the compounds, and kits including the compounds. The compounds may include detection moieties such as fluorophores that may allow for selective detection of Hsp90 in a sample.
In spite of the wide availability of various near‐infrared (NIR) fluorophores as labeling reagents, there are few functional NIR fluorescentprobes for which change in the absorption and/or fluorescence spectra upon specific reaction with biomolecules is seen. The widely used photoinduced electron‐transfer mechanism is unsuitable for NIR fluorophores, such as tricarbocyanines, because their long excitation
vivo in a real-time way by giving near infrared (NIR) fluorescence and photoacoustic signal. By co-delivering antiangiogenesis and chemotherapeutic reagents, the tumor can be significantly suppressed, meanwhile with a low systematic toxicity. Hopefully, this work can offer new insights in designing sophisticated antitumor strategy.
