生物硫醇涉及不同的生理和病理过程,而生物硫醇的异常水平与多种疾病有关。区别检测这些分子并探索其在活生物样品中的固有转化是至关重要的。在此,合理设计了基于NBD(7-硝基-1,2,3-苯并恶二唑)硫醚/醚/胺硫解的双反应和双猝灭荧光探针,用于分别检测H 2 S和Cys / Hcy。探头2是能够感测ħ 2 S(λ EX / EM =455分之405纳米)和Cys /同型半胱氨酸(λ EX / EM =五百五十〇分之四百七十纳米)在GSH的在含水缓冲液的存在。而且,该探针不仅可以用于外源H 2的可视化。活细胞中的S和Cys,但也成功展示了验证Cys内生H 2 S生物合成的潜力。

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.
the sub‐100 nM range, with high selectivity over inhibition of the endocannabinoid‐degrading enzyme fatty acid amide hydrolase; two compounds were virtually equipotent with 1. Interestingly, profound activity differences were observed between analogues in which either of the two methoxy substituents in the head group had been replaced by the same bulkier alkoxy group. Some of the compounds described here
The knowledge of the mechanism used by vectors to gain access to cell interiors is key to the development of effective drug delivery tools for different pathologies.
向细胞内部进入的载体机制的了解对于开发针对不同病理的有效药物传递工具至关重要。

A nanocomplex containing a delivery agent and a pharmaceutical agent. The nanocomplex has a particle size of 50 to 1000 nm, the delivery agent binds to the pharmaceutical agent via non-covalent interaction or covalent bonding, and the pharmaceutical agent is a modified peptide or protein formed of a peptide or protein and an added chemical moiety that contains an anionic group, a disulfide group, a hydrophobic group, a pH responsive group, a light responsive group, a reactive oxygen species responsive group, or a combination thereof.
The present invention relates to compounds with a benzoxadiazolyl amine structure which are capable of inhibiting the activation or the biological activity of p38 mitogen-activated protein kinase (MAPK) and the use thereof in the treatment of a disease that can be alleviated by means of inhibiting the activation or the biological activity of said p38 MAPK, for example, an inflammatory disease or a disease presenting with pain.
