Hu, Wei;Qiang, Taotao;Chai, Li;Liang, Tianyu;Ren, Longfang;Cheng, Fei;Li, Chunya;James, Tony D. research published 《 Simultaneous tracking of autophagy and oxidative stress during stroke with an ICT-TBET integrated ratiometric two-photon platform》, the research content is summarized as follows. Over recent years, fluorescent probes exhibiting simultaneous responses to multiple targets have been developed for in situ, real-time monitoring of cellular metabolism using two photon fluorescence sensing techniques due to numerous advantages including ease of operation, rapid reporting, high resolution, long visualization time and being non-invasive. However, due to interference from different fluorescence channels during simultaneous monitoring of multiple targets and the lack of ratiometric capability amongst the available probes, the accuracy in tracing metabolic processes has been restricted. With this research, using a through-bond energy transfer (TBET) mechanism, we designed a viscosity and peroxynitrite (ONOO^–) mitochondria-targeting two-photon ratiometric fluorescent probe Mito-ONOO. Our results indicated that with decreasing levels of mitochondrial viscosity and increasing levels of ONOO^–, the maximum of the emission wavelength of the probe shifted from 621 nm to 495 nm under 810 nm two-photon excitation. The baselines for the two emission peaks were significantly separated (Δλ = 126 nm), improving the resolution and reliability of bioimaging. Moreover, by ratiometric anal. during oxygen-glucose deprivation/reoxygenation (OGD/R, commonly used to simulate cell ischemia/reperfusion injury), the real-time visualization of the metabolic processes of autophagy and oxidative stress was possible. Our research indicated that during cellular oxygen-glucose deprivation/reoxygenation, cells produce ONOO^–, causing cellular oxidative stress and cellular autophagy after 15 min, as such Mito-ONOO exhibits the potential for the monitoring and diagnosis of stroke, as well as providing insight into potential treatments, and drug design.

Huang, Lei;Tang, Feiying;Hao, Fang;Zhao, Hao;Liu, Wenyuan;Lv, Yang;Liu, Pingle;Xiong, Wei;Luo, Hean research published 《 Tuning the Electron Density of Metal Nickel via Interfacial Electron Transfer in Ni/MCM-41 for Efficient and Selective Catalytic Hydrogenation of Halogenated Nitroarenes》, the research content is summarized as follows. Catalytic hydrogenation of nitrocompound is an environment-benign strategy for the production of important aniline intermediates. Herein, MCM-41 was synthesized from sepiolite via in situ self-assembled method and the modified MCM-41 supported nickel-based catalysts were prepared and applied in halogenated nitrobenzene hydrogenation to halogenated aniline. Compared with Ni/MCM-41, the Sn or La modified MCM-41 supported nickel-based catalysts exhibited better catalytic performance. The electron transfer from Sn or La species to Ni led to a downshift in d-band center of Ni, which was in favor of H desorption and hence promoted hydrogenation activity. It was found that chloronitrobenzene preferred the tilted adsorption orientation mode on the surface of Ni-Sn and Ni-La₂O₃ to flat adsorption orientation. Moreover the C-Cl bond scission on Ni-Sn and Ni-La₂O₃ were thermodynamically unfavorable in comparison with pure-phased Ni, leading to higher selectivity to chloroaniline. Ni/LaMCM-41-NH₂ gave the best catalytic performance of 100% conversion and 99.6% selectivity to m-chloroaniline.

Huang, Mingming;Wu, Zhu;Krebs, Johannes;Friedrich, Alexandra;Luo, Xiaoling;Westcott, Stephen A.;Radius, Udo;Marder, Todd B. research published 《 Ni-Catalyzed Borylation of Aryl Sulfoxides》, the research content is summarized as follows. A nickel/N-heterocyclic carbene (NHC) catalytic system has been developed for the borylation of aryl sulfoxides with B₂(neop)₂ (neop=neopentyl glycolato). A wide range of aryl sulfoxides with different electronic and steric properties were converted into the corresponding arylboronic esters in good yields. The regioselective borylation of unsym. diaryl sulfoxides was also feasible leading to borylation of the sterically less encumbered aryl substituent. Competition experiments demonstrated that an electron-deficient aryl moiety reacts preferentially. The origin of the selectivity in the Ni-catalyzed borylation of electronically biased unsym. diaryl sulfoxide lies in the oxidative addition step of the catalytic cycle, as oxidative addition of methoxyphenyl 4-(trifluoromethyl)phenyl sulfoxide to the Ni(0) complex occurs selectively to give the structurally characterized complex trans-[Ni(ICy)₂(4-CF₃-C₆H₄){(SO)-4-MeO-C₆H₄}] 4. For complex 5, the isomer trans-[Ni(ICy)₂(C₆H₅)(OSC₆H₅)] 5–i was structurally characterized in which the Ph sulfinyl ligand is bound via the oxygen atom to nickel. In solution, the complex trans-[Ni(ICy)₂(C₆H₅)(OSC₆H₅)] 5–i is in equilibrium with the S-bonded isomer trans-[Ni(ICy)₂(C₆H₅)(SOC₆H₅)] 5, as shown by NMR spectroscopy. DFT calculations reveal that these isomers are separated by a mere 0.3 kJ/mol (M06/def2-TZVP-level of theory) and connected via a transition state trans-[Ni(ICy)₂(C₆H₅)(η²-{SO}-C₆H₅)], which lies only 10.8 kcal/mol above 5.

The selective formal insertion (homologation) of a carbon unit bridging the two trifluoroacetamidoyl chlorides (TFAICs) units is reported. The tactic is levered on a highly chemoselective homologation-metalation-acyl nucleophilic substitution sequence which precisely enables to assemble novel trifluoromethylated β-diketiminates within a single synthetic operation. Unlike previous homologations conducted with LiCH₂Cl furnishing aziridines, herein we exploit the unique capability of iodomethyllithium to act contemporaneously as a C1 source (homologating effect) and metalating agent. The mechanistic rationale grounded on exptl. evidences supports the hypothesized proposal and, the structural anal. gathers key aspects of this class of valuable ligands in catalysis. Thus, e.g., treatment of imidoyl chloride I (1.0 equiv) with LiCH₂I (1.3 equiv) for homologation followed by addition of a second 1.0 equiv of I and a second portion of LiCH₂I (1.5 equiv) for metalation afforded (Z,Z)-II (91%).

This paper describes the stepwise aza-Wittig reaction of 1,1′-bis(triphenylphosphoranylidenamino)-ferrocene with a paramagnetic isocyanate, namely, 3-isocyanato-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrole-1-oxyl, and then with substituted aryl isocyanates. The intermediate product (a paramagnetic betaine), which is the product of an intramol. nucleophilic attack of the nitrogen atom of the iminophosphorane moiety on the carbon atom of the carbodiimide functional group, was isolated and structurally characterized. Subsequent interaction of the betaine with aryl isocyanates under mild conditions gave spin-labeled ferrocenophanes with the 1,3-diazetidine-2,4-diimine coupler. It was found that the mutual arrangement of the substituents in the latter depends on the nature of the substituents in the aryl isocyanate. Iodophenyl derivatives of 1,3-diazetidine-2,4-diimines were cross-coupled with the gold(I) nitronyl nitroxide-2-ide complex, thus yielding diradicals: metallocenophanes functionalized with various types of nitroxide substituents.

Habgood, Matthew;Seiferth, David;Zaki, Afroditi-Maria;Alibay, Irfan;Biggin, Philip C. research published 《 Atomistic mechanisms of human TRPA1 activation by electrophile irritants through molecular dynamics simulation and mutual information analysis》, the research content is summarized as follows. The ion channel TRPA1 is a promiscuous chemosensor, with reported response to a wide spectrum of noxious electrophilic irritants, as well as cold, heat, and mechanosensation. It is also implicated in the inception of itch and pain and has hence been investigated as a drug target for novel analgesics. The mechanism of electrophilic activation for TRPA1 is therefore of broad interest. TRPA1 structures with the pore in both open and closed states have recently been published as well as covalent binding modes for electrophile agonists. However, the detailed mechanism of coupling between electrophile binding sites and the pore remains speculative. In addition, while two different cysteine residues (C621 and C665) have been identified as critical for electrophile bonding and activation, the bound geometry has only been resolved at C621. Here, we use mol. dynamics simulations of TRPA1 in both pore-open and pore-closed states to explore the allosteric link between the electrophile binding sites and pore stability. Our simulations reveal that an open pore is structurally stable in the presence of open pockets in the C621/C665 region, but rapidly collapses and closes when these pockets are shut. Binding of electrophiles at either C621 or C665 provides stabilization of the pore-open state, but mols. bound at C665 are shown to be able to rotate in and out of the pocket, allowing for immediate stabilization of transient open states. Finally, mutual information anal. of trajectories reveals an informational path linking the electrophile binding site pocket to the pore via the voltage-sensing-like domain, giving a detailed insight into the how the pore is stabilized in the open state.

144-48-9, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.

2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.
An alkylating sulfhydryl reagent. Its actions are similar to those of iodoacetate., Electric Literature of 144-48-9
