Here, we present a thorough theoretical study of the adsorption of acrolein (ACO), acrylonitrile (ACN), and acrylamide (ACA) on Cu(100) surface. For this purpose, we have used the density functional theory, imposing periodic boundary conditions to have a correct description of the electronic band structure of the metal and including dispersion forces through two different schemes: the D2 method of Grimme and the vdW-DF. We have found several adsorption geometries. In all of them, the vinyl group together with the amide (in ACA), ciano (in ACN), and carbonyl (in ACO) groups, is highly involved. The highest adsorption energy is found for acrylamide, followed by acrolein and the lowest for acrylonitrile (depending on the level of theory employed 1.0, and 0.9 eV, respectively). We show that a strong coupling between the pi electronic system (both occupied and virtual orbitals) and the electronic levels of the metal is mainly responsible of the chemisorption. As a consequence, electronic density is transferred from the surface to the molecule, whose carbon atoms acquire a partial sp(3) hybridization. Lone-pair orbitals of the cyano, amide, and carbonyl groups also play a role in the interaction. The simulations and following analysis allow to disentangle the nature of the interaction, which can be explained on the basis of a simple chemical picture: donation from the occupied lone pair and pi orbitals of the molecule to the surface and backdonation from the surface to the pi* orbital of the molecule (pi-backbonding).

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 6027-13-0, Name is (S)-2-Amino-4-mercaptobutanoic acid, SMILES is N[C@@H](CCS)C(O)=O, in an article , author is Kirkedal, Christian, once mentioned of 6027-13-0, HPLC of Formula: https://www.ambeed.com/products/6027-13-0.html.

The YcaO superfamily of proteins catalyzes the phosphorylation of peptide backbone amide bonds, which leads to the formation of azolines and azoles in ribosomally synthesized and post-translationally modified peptides (RiPPs). Bottromycins are RiPPs with potent antimicrobial activity, and their biosynthetic pathway contains two, divergent, stand-alone YcaO enzymes, IpoC and PurCD. From an untargeted metabolomics approach, it had been suggested that PurCD acts with a partner protein to form the 12-membered rnacroamidine unique to bottromycins. Here we report the biochemical characterization of IpoC and PurCD. We demonstrate that IpoC installs a cysteine-derived thiazoline, whereas PurCD alone is sufficient to create the macroamidine structure. Both enzymes are catalytically promiscuous, and we generated 10 different macroamidines. Our data provide important insights into the versatility of YcaO enzymes, their ability to utilize different nucleophiles and provide a framework for the creation of novel bottromycin derivatives with enhanced bioactivity.

Reducing or eliminating organic solvent use in pharmaceutical manufacturing is perhaps the most effective way to reduce the environmental, health, and safety impacts of drug substance manufacturing. With this in mind, we have developed a process to manufacture an investigational 6-HT4 receptor agonist that is conducted almost entirely in water, including multiple controlled isolations. Key transformations carried out in aqueous media include a benzimidazole cyclization, amide bond formation, reductive amination, and a selective oxidation of an aliphatic alcohol. Compared to the first-generation manufacturing process using organic solvents, the aqueous process described here uses 77% less material inputs, 94% less organic solvent, and, surprisingly, 48% less water, while improving overall yield from 35% to 56%.

Despite the existence of multimodal therapy concepts, glioblastoma remains a tumor type with one of the worst prognoses. In particular, the poor prognosis is due to the lack of therapeutic efficacy of chemical agents and irradiation in hypoxic tumor areas. New therapeutic strategies could improve the treatment of glioblastoma. In this study, we investigated the therapeutic efficacy of a conjugate of cisplatin (DDP), a widely used chemotherapeutic agent, and betulinic acid (BA), a natural product from plane tree bark, in glioblastoma cells under different oxygen conditions. We investigated the effects of the BA-DDP conjugate kappa N’,N ”-{3-acetyloxy-BA-28-[2(2-aminoethyl)aminoethyl]amide} dichlorido platinum(II) (APC) and its precursor 3-acetyloxy-BA-28-[2-(2-aminoethyl)aminoethyl]amide (DE9B) on cytotoxicity, cell growth, apoptosis, migration and radiosensitivity compared to BA or DDP alone under different oxygen conditions. Based on the EC50 values, the precursor DE9B exhibited the strongest cytotoxic effects of the analyzed chemotherapeutic agents. The BA-DDP conjugate APC achieved a moderate cytotoxic effect in glioma cells. Both of the newly developed agents induced cell growth delay, apoptosis and inhibition of migration. Furthermore, additive effects could be achieved in combination with irradiation. In contrast to those of BA and DDP, the cell biological effects of APC and DE9B were not influenced by the oxygen concentration. In this study, the linking of BA and DDP did not produce a compound with additive therapeutic effects on glioblastoma cell lines in vitro. Nevertheless, the results of this study suggest that the precursor DE9B is an effective BA derivative for the treatment of glioblastoma in vitro.

The report describes the effect of TiO2 nano particles on the hydrogenation characteristics of promising Li-Mg-N-H hydrogen storage system. The effect of different particle size of TiO2 (200, 25 and 7 nm) on de/re-hydrogenation characteristics of Mg(NH2)(2)/LiH mixture has been investigated. Desorption kinetics of Li-Mg-N-H system with 25 nm TiO2 gets enhanced upto similar to 25% as compared to the pristine material kinetics at 453 K (180 degrees C). The report also deals mechanistic approach for hydrogen release from Li-Mg-N-H system in the presence of TiO2 nanoparticles through XPS analysis of catalyzed sample at various stages of reaction. The XPS analysis confirms that during dehydrogenation nitrogen atom present in Li-Mg-N-H system share their lone pair electrons to Ti (present in TiO2) and provides an alternate decomposition path which has lower activation energy for dehydrogenation.

Tyrosinase, a copper-containing enzyme existing widely in plants, animals and microorganisms, usually serves as an important biomarker in melanoma, and is also related to hyperpigmentation of the skin, melasma, age spots and albinism. At present, only one bioluminescent probe has been applied to image tyrosinase in cells. Thus, it’s of great significance to develop a new bioluminescent probe that can detect tyrosinase in living cells and in live animals. In the current work, we report a new BL probe, TyrBP-3, which not detect tyrosinase in vitro and in living cells, but can also visualize the level of tyrosinase activity in tumors of living animals. In summary, TyrBP-3 is the first bioluminescent probe that can image tyrosinase on a cellular level. Hence, we anticipate that TyrBP-3 can be a good tool to monitor tyrosinase in complex biosystems in the future.

Methamphetamine (Meth) is an addictive psychostimulant whose abuse is intimately linked to increased risks for HIV-1 infection. Converging lines of evidence indicate that Meth also aggravates the symptoms of HIV-associated neurocognitive disorders (HAND), though the underlying mechanisms remain poorly understood. By using the lipophilic antioxidant N-acetylcysteine amide (NACA) as an interventional agent, we examined the roles of oxidative stress in autophagy and apoptosis induced by HIV-Tat (the transactivator of transcription), Meth or their combined treatment in human SH-SY5Y neuroblastoma cells and in the rat striatum. Oxidative stress was monitored in terms of the production of intracellular reactive oxygen species (ROS) and antioxidant reserves including glutathione peroxidase (GPx) and Cu,Zn-superoxide dismutase (SOD). NACA significantly reduced the level of ROS and restored GPx and SOD to levels comparable to that of normal control, implying a cytoprotective effect of NACA against oxidative stress elicited by Tat- and/or Meth. Protein expression of mammalian target of rapamycin (mTOR) was measured in SH-SY5Y cells and in the rat striatum to further explore the underlying mechanism of NACA protect against oxidative stress. The results support a beneficial effect of NACA in vivo and in vitro through rectification of the mTOR signaling pathway. Collectively, our study shows that NACA protects against Meth and/or Tat-induced cellular injury in vitro and in the rat striatum in vivo by attenuating oxidative stress, apoptosis and autophagy, at least in part, via modulation of mTOR signaling.

The direct transition-metal-free acylation of amides with functionalized Grignard reagents by highly chemoselective N-C cleavage under kinetic control has been accomplished. The method offers rapid and convergent access to functionalized biaryl ketones through transient tetrahedral intermediates. The direct access to functionalized Grignard reagents by in situ halogen-magnesium exchange promoted by the versatile turbo-Grignard reagent (iPrMgCl.LiCl) permits excellent substrate scope with respect to both the amide and Grignard coupling partners. These reactions enable facile, operationally simple and chemoselective access to tetrahedral intermediates from amides under significantly milder conditions than chelation-controlled intermediates. This novel direct two-component coupling sets the stage for using amides as acylating reagents in an alternative paradigm to the metal-chelated approach, acyl metals and Weinreb amides.

In this paper, preparation and the inhibition properties of a cationic hyperbranched polymer (HBP-HTC) on clay hydration and swelling were researched. The properties of HBP-HTC, including chemical structure, cationic degree, and molecular weight, were investigated by using Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic hydrogen spectroscopy, sodium tetraphenylborate back titration, and gel permeation chromatography. The obtained results indicated that HBP-HTC was a hyperbranched unsaturated polyester amide with a low molecular weight and high cation degree, with corresponding values of 34,730 and 43.26%, respectively. The inhibition properties of HBP-HTC on clay hydration and swelling were evaluated through linear anti-swelling, water flushing, rolling recovery, and core flooding tests. The results showed that HBP-HTC has an excellent anti-swelling and long-term effect. When 1.0 wt % HBP-HTC was added, the initial anti-swelling rate reached 91.58%. After flushing 10 times with water, the anti-swelling rate remained at 85%. The two cutting rolling recoveries exceed 70%, and the permeability damage rate of HBP-HTC to the core was lower, just 7.03%, which indicated that HBP-HTC effectively inhibited the clay hydration and swelling, had an excellent anti-washing capacity, and also reduced the permeability damage to the core in the process of waterflooding. The inhibiting mechanism of HBP-HTC was revealed by FTIR, zeta potential, X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and contact angles tests. The results exhibited that HBP-HTC neutralized negative charges on the surface of clay to compress the electric double layer. Besides, HBP-HTC was strongly adsorbed on the surface of clay particles due to the highly concentrated cations and hydrogen bonds at the end of the molecule and a large number of hyperbranched molecular chains and formed a waterproof polymer film, preventing water invasion of the clay interlayer, inhibiting clay hydration swelling.
