Owing to the inherent ability of amides to chelate transition-metal catalysts, amide-directed C–H activation reactions constitute a major tactic in directed C–H activation reactions. While the conventional procedures for these reactions usually involve prior preparation and purification of amide substrates before the C–H activation, the step economy is actually undermined by the operation of installing the directing group (DG) and related substrate purification. In this context, directed C–H activation via in situ amidation of the crude material provides a new protocol that can significantly e

Over the last few decades, significant efforts have been put forth towards the C−H bond group functionalization by transition-metalcatalysis and organocatalysis. Several efficient strategies to convert C-H bond to other groups C-C, C-N, C-O bonds have been implemented. The most attractive C-H bond functionalization was the C-H heterocyclic compounds activation that is practical method in organic synthesis. The new C–C, C–N and C–O bond as formed from the C-H bond activation by two diverse ways metal catalysis and/or organocatalysis. The most important is the synthesis o

c-Src has been shown to activate NF-κB (nuclear factor κB) following H/R (hypoxia/reoxygenation) by acting as a redox-dependent IκBα (inhibitory κB) tyrosine kinase. In the present study, we have investigated the redox-dependent mechanism of c-Src activation following H/R injury and found that ROS (reactive oxygen species) generated by endosomal Noxs (NADPH oxidases) are critical for this process. Endocytosis following H/R was required for the activation of endosomal Noxs, c-Src activation, and the ability of c-Src to tyrosine-phosphorylate IκBα.

Thermolysis of Cp*W(NO)(Np)(η³-CH₂CHCHSiMe₃) generates a 16-electron allene intermediate complex that selectively activates hydrocarbons at their methyl groups. In the case of linear alkanes, only terminal activation is observed. This selectivity persists in the presence of an ether functionality, but not of other oxygen-containing substrates such as aldehydes and alcohols. With these latter substrates, oxidation of the complex to Cp*W(O)₂Np has been noted. The existence of the allene intermediate has been verified by two thermolytic experiments, and kinetic studies show that Cp*W(NO)(Np)(η³-

Platelet stimulation has been shown to result in a rise of cytosolic pH (pHi) as a result of an activation of a Na+/H+ antiport. We have investigated the role of pH in Ca2+ mobilization in human platelets. pHi and free Ca2+, {Ca2+)i, were measured in platelets loaded with the fluorescent indicators BCECF and quin2, respectively. Stimulation of platelets by either thrombin or OAG, an activator of protein kinase C (Pk-C), increased pHi. Pretreatment of platelets with inhibitors of Pk-C, trifluoperazine (TFP) or sphingosine (SPH), blocked the stimulus-induced rise in pHi, suggesting a role of Pk-

It is long known that platelet aggregation and secretion are accompanied by acidification of the extracellular medium. Much of the proton extrusion results from hydrolysis of ATP generated in the glycolytic pathway and liberation of secretion granules, which are slightly acidic. Recent eyidence points at a third source for extracellular protons.Following early observations (1) that epinephrine-induced platelet functions depended on extracellular Na+ (Na+ o ), it became evident that platelets possess a Na+ /H+ antiport, which regulates the cytosolic pH (pH.) via stochiometric exchange of intrac

The mechanism of alkane C-H bond activation by transition metal complexes such as CpM(CO)2 (M=Rh, Ir) has been intensely studied because it represents a first step in a catalytic process using unreactive hydrocarbons.[1] The bond activation reaction starts with the formation of monocarbonyl intermediates such as CpRh(CO). These species have been detected in the gas phase[2] and in liquefied rare Kr and Xe[3] by µs time resolved IR spectroscopy. Unfortunately, the subsequent oxidative insertion of CpRh(CO) into the C-H bond is not well understood due to its rapid rate and low quantum yield (~1%

In this research, a series of copper complexes containing polypyridyl ligands were designed to study the influence from ligands, nuclearity, solvents and secondary coordination on reactivity toward small-molecule activation. This structure-reactivity relationship was used in investigation for oxygen reduction reactions (ORR), and applied in detection of ascorbic acid (AsH₂). Firstly, copper (II) complexes containing polypyridyl derivatives ligands (i.e., Cu(dpa), Cu(adpa) and Cu₂ (addpa)) were synthesized and fully characterized by elemental analysis, mass spectrometry and X-ray crystallograph

Bacterial cellulose (BC) was investigated as a novel material for preparing activated carbons. BC was dried by heating and it was carbonized with a chemical activation process using phosphoric acid (H₃PO₄) as an activating agent at different temperatures (400, 500 and 600 °C). The properties of the activated carbons were characterized such as chemical property, structure, pore size, thermal property by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N₂ -physisorption (BET), scanning electron microscopy (SEM) , thermal gravimetric (TGA). The obtained BC activated carbo

A number of techniques for air pollutant removals are available such as adsorption, biofiltration and incineration. However, these techniques require further treatment and/or are energy-intensive leading to high treatment costs. Both plasma and photocatalysis are promising alternatives since these two techniques can be operated at ambient conditions resulting in low energy consumption as compared to the conventional methods. The main objective of this work was to develop a combined plasma and photocatalytic system for VOC removals. A four-stage plasma and photocatalytic reactor system was setu
