The potential role of nine thiols as chemical protectors against the toxicity of paracetamol (acetaminophen, APAP) and its meta analogue N-acetyl-m-aminophenol (AMAP) was investigated using the density functional theory. They are glutathione (GSH), N-acetylcysteine (NAC), NAC amide (NACA), tiopronine (TPR), dihydrolipoic acid (DHL), 6-mercaptopurine (6MP), 6-thioguanine (6TG), 2,3-dimercaprol (DMC), and D-penicillamine (PNA). The investigation was focused on the toxic effects derived from protein arylation at cysteine residues, induced by the quinone imines formed from APAP and AMAP. On the basis of both thermochemical and kinetic considerations, with the exceptions of 6MP and 6TG, the investigated thiols may be useful in protecting the chemical integrity of cysteine residues in proteins from arylation by quinone imines. The order of efficiency for that purpose is predicted to be NAC > GSH > TPR > NACA > DMC > DHL. However, considering physicochemical properties that may affect bioavailability and cell permeability, DHL seems to be the best prospect to be orally supplied.

UiO-66 was successfully synthesized in the absence of any amide solvents and hydrochloric acid by using the dry-gel conversion (DGC) method for the first time. The prepared UiO-66 samples (denoted as UiO-66-DGC) were characterized by XRD, SEM, TGA, CO2 adsorption, NH3-TPD, and N-2 adsorption. The results showed that the UiO-66-DGC-E sample synthesized by using ethanol as solvent has similar crystallinity and morphology to the UiO-66 sample prepared by the conventional solvothermal method (denoted as UiO-66-S). However, it has more linker deficiencies, indicating the presence of more defects exposed in Zr clusters. As a resut, the prepared UiO-66-DGC-E sample exhibited high catalytic activity and reusability in esterification. This preparation method provides a new alternative method for the efficient and eco-friendly synthesis of metal organic frameworks (MOFs) and modification of their properties.

Janus kinase 1 (JAK1) plays a key role in most cytokine-mediated inflammatory and autoimmune responses through JAK/STAT signaling; thus, JAK1 inhibition is a promising therapeutic strategy for several diseases. Analysis of the binding modes of current JAK inhibitors to JAK isoforms allowed the design of N-alkyl-substituted 1-H-pyrrolo[2,3-b] pyridine carboxamide as a JAK1-selective scaffold, and the synthesis of various methyl amide derivatives provided 4- ((cis-1- (4-chlorobenzyl)-2-methylpiperidin-4-yl) amino-N-methyl-1H-pyrrolo[2,3-b]pyridine-5-carboxamide (31g) as a potent JAK1-selective inhibitor. In particular, the (S,S)-enantiomer of 31g (38a) exhibited excellent potency for JAK1 and selectivity over JAK2, JAK3, and TYK2. On investigating the effect of 31g on hepatic fibrosis, it was found that it reduces the proliferation and fibrogenic gene expression of TGF-beta-induced hepatic stellate cells (HSCs). Specifically, 31g significantly inhibited TGF-beta-induced migration of HSCs at 0.25 mu M in wound-healing assays.

Molecular dynamics study of coil-to-globule transition in a thermo-responsive oligomer bound to various surfaces: hydrophilic surfaces stabilize the coil form

The structural and dynamical properties of 40-mer of thermo-responsive polymer PNIPAM covalently bound to different surfaces have been studied, at different temperatures, by means of molecular dynamics simulations. Evolution of the radius of gyration, R-g, of the polymer chain and radial distribution functions (RDFs) calculated for the carbon atoms of the PNIPAM backbone with water oxygens and for the hydrogen atom of the amide groups with water oxygens indicate that functionalized surfaces affect the coil-to-globule transition of PNIPAM, by means of electrostatic interactions, increasing the lower critical solution temperature (LCST) of the polymer. Such interactions, mainly represented by a H-bond, hinder the transition in the globular form while hydrophobic groups on the surface, such as -OCH3, contribute to the globular collapse. A significant alteration in the arrangement of water molecules around the polymer is testified by: (i) the absence of the second peak in the RDF between the C atoms of the PNIPAM backbone and the O atoms of water at the same temperature at which the radius of gyration decreases; (ii) the height of both the first and the second peak of the RDF between the H atom of the amide groups and water O atoms decreases when the temperature increases above the LCST. Finally, the H-bond autocorrelation function indicates that: (i) hydrogen bonds between the bound-to-surface PNIPAM acceptor groups (O?C?) and the H atoms of water molecules are less persistent than H-bonds formed between the free PNIPAM acceptor groups and water; (ii) H-bonds between the PNIPAM acceptor groups and hydroxyl groups on the quartz surface are longer lived than those formed on graphene oxide.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 140-95-4. HPLC of Formula: https://www.ambeed.com/products/140-95-4.html.

Effect of aromatic core on the supramolecular chirality of L-phenylalanine derived assemblies

Constructing chiral supramolecular assemblies with controllable handedness has attracted much attention in materials science, biology and chemistry, owing to their outstanding photophysical properties and novel biological effects. Herein, four gelators derived from L-phenylalanine were synthesized and their gel formation and self-assembled nanostructures were investigated. It was found that the handedness, helical pitch and diameter of these self-assemblies were successfully controlled by tuning the structure of central aromatic groups. Left- and right-handed nanofibers with different dimensions were obtained, showing configuration-regulated assembly behavior. These self-assemblies were further characterized by CD, FTIR, SEM, and UV-vis, and the results suggested that the pi-pi stacking among the central aromatic rings and hydrogen bonds among the amide groups at the terminals play important roles in the formation of these self-assemblies.

Computational and Experimental Study of Turbo-Organomagnesium Amide Reagents: Cubane Aggregates as Reactive Intermediates in Pummerer Coupling

The dynamic equilibria of organomagnesium reagents are known to be very complex, and the relative reactivity of their components is poorly understood. Herein, a combination of DFT calculations and kinetic experiments is employed to investigate the detailed reaction mechanism of the Pummerer coupling between sulfoxides and turbo-organomagnesium amides. Among the various aggregates studied, unprecedented heterometallic open cubane structures are demonstrated to yield favorable barriers through a concerted anion-anion coupling/ S-O cleavage step. Beyond a structural curiosity, these results introduce open cubane organometallics as key reactive intermediates in turbo-organomagnesium amide mixtures.

Ni-Catalyzed cross-coupling reactions of N-acylpyrrole-type amides with organoboron reagents

The catalytic conversion of amides to ketones is highly desirable yet challenging in organic synthesis. We herein report the first Ni/bisNHC-catalyzed cross-coupling of N-acylpyrrole-type amides with arylboronic esters to obtain diarylketones. This method is facilitated by a new chelating bis-NHC ligand. The reaction tolerates diverse functional groups on both arylamide and arylboronic ester partners including sensitive ester and ketone groups.

Synthesis of hydroxylated fatty amide from underutilized seed oil of Khaya senegalensis: a potential green inhibitor of corrosion in aluminum

Background: Corrosion is a serious problem all over the world. Most currently used approach to control corrosion have short comings which necessitates the search for novel materials that are green, cheap, from renewable source, and eco-friendly that can be used to combat this problem of corrosion control. Method: Khaya senegalensis fatty hydroxylamide (KSFA) was synthesized from K. senegalensis seed oil via simple reaction route involving esterification, transesterification, hydroxylation, and amidation reaction. KSFA was characterized using Fourier-transform infrared (FTIR), nuclear magnetic resonance ((HNMR)-H-1), CHN elemental analyzer, particle size distribution (PSD), X-ray diffractometer, zeta potential, thermogravimetric analysis (TG), thermogravimetric-mass spectrometer (TG-MS), and scanning electron micrograph (SEM) coupled with energy dispersion spectroscopy (EDS). Inhibitory effect of KSFA on corrosion of aluminum (Al) in 0.5 M HCl was studied at different concentrations of KSFA and temperatures using weight loss method. Result: Result from gas chromatography (GC) revealed oil of K. senegalensis to predominantly contain C18:1 (68.46%) fatty acid. Hydroxyl and amide functional groups present in KSFA were confirmed by FTIR and (HNMR)-H-1. TG analysis revealed loss in mass around 80-190, 200-450, and above 450 degrees C while TG-MS revealed five different masses with m/z values 16, 17, 18, 28, and 44. Corrosion inhibition capacity of KSFA was by surface adsorption, which is spontaneous, and physisorption and described by Langmuir isotherm. The corrosion inhibition efficiency of KSFA increased with increase in its concentration while its corrosion rate reduced with increase in concentration. Conclusion: The inhibition efficiency of 90.43% exhibited by KSFA and the fact that KSFA was synthesized via non-hazardous process from a renewable sourced biomass is an indication that KSFA is a potential green and efficient inhibitor of corrosion in aluminum. KSFA is simple to use as an inhibitor and easy to prepare.
