Study of surface heterogeneity and nitrogen functionalizing of biochars: Molecular modeling approach

The functionality of biochar surfaces depends on the nature of the feedstock, pyrolysis temperature, and residence time. In this study, molecular modeling was used to determine the types of functionalization that could enhance adsorption and to pre-screen the target adsorbate for the sake of minimizing experimental time. The impact of a single functional group and interaction between them (including nitrile, methyl, ether, furan, carboxyl, hydroxyl, amine, and amide) on the adsorption of target adsorbate onto biochar was investigated. Among biochars inherent functional groups simulated, the lowest energy of adsorption (highest adsorption) occurred with carboxyl and hydroxyl for CO2 adsorption due to hydrogen bonding. The simulations showed adding amine/amide functional groups to the biochar surface enhanced CO2 adsorption, because of stronger bonding. The simulation results were compared against experimental results and the thermodynamic properties were satisfactorily matched. The overall heat of adsorption of H2S was lower than CO2, but the average Gibbs free energy was approximately the same, indicating CO2 could replace H2S in initial screening adsorption experiments for this type of biochar, reducing costs, risk and toxicity concerns of using H2S. This is an example of potentially how the models can be used to better design experiments. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis of 1-pyrroline 1-oxides analogous to pseudouridine

Pseudouridine (psi-uridine, Psi) aza’-analogues with a 5,5-bis(hydroxymethyl)-1-pyrrolin-2-yl 1-oxide as the glycone mimic were obtained by the addition of (2,4-dimethoxypyrimidin-5-yl)magnesium bromide to 1-aza-7,14-dioxadispiro[4.2.5.2]pentadec-1-ene 1-oxide (3), followed by oxidation and removal of the protecting groups. The analogous synthesis from (2,4-dimethoxypyrimidin-5-yl)lithium and 3 was less efficient; in the first step of the reaction sequence, competing dimerisation of 3 predominated over addition of the organolithium agent to 3.

Synthesis and structure determinations of complexes containing a five-membered lactam structure based on organohydrazido(2-) ligands

Acid-catalyzed reactions of the hydrazido(2-) complexes cis,mer-[WX(2)(NNH2)(PMe(2)Ph)(3)] (X=Cl, Br) with phthalaldehyde gave the (phthalimidin-2-yl)imido complexes cis,mer-[WX(2)(NNCH2C6H4CO)(PMe(2)Ph)(3)], via the condensation of the terminal NH2 group with one of the formyl groups and the following cyclization to form a phthalimidine ring. Crystal structure of the chloro complex 3a was unambiguously determined by X-ray analysis. Reaction of 3a with HBr liberated the (phthalimidin-2-yl)imido ligand as 2-aminophthalimidine in moderate yield, while treatment of 3a with KOH in THF selectively cleaved the N-N bond to give phthalimidine. A similar condensation of the hydrazido(2-) complex trans-[WF(NNH2)(dppe)(2)](+) (8a(+); dppe=Ph(2)PCH(2)CH(2)PPh(2)) with phthalaldehyde resulted in the formation of the diazoalkane complex trans-[WF(NN=CHC6H4CHO)(dppe)(2)](+). However, further treatment of the latter complex with AlCl3 afforded the corresponding (phthalimidin-2-yl)imido complex trans-[WF(NNCH2C6H4CO)(dppe)(2)](+). When 8a(+) and its molybdenum analogue were reacted with 2,5-dimethoxy-2,5-dihydrofuran in the presence of a catalytic amount of acid, trans-[M(NNCH=CHCH2CO)(dppe)(2)](+) (11(+); M=Mo, W) was formed as the kinetic product, which gradually isomerized to the thermodynamically more stable compound trans-[MF(NNCH2CH=CHCO)(dppe)(2)](+) (12(+)). Both 11(+) and 12(+) (M=W) were crystallographically characterized, and the mechanism for the isomerization of 11(+) to 12(+) was proposed based on the results of the H-1 NMR measurements.

DETERMINATION OF 3-HYDROXY-3-PYRROLINE-2-ONE IN URINE AND STUDY OF ITS EXCRETION FROM THE ORGANISM OF LABORATORY ANIMALS

cological activity. Currently, this group continues to expand. By the employees of Perm State Pharmaceutical Academy (PSPA), ruled by Professor V.L. Gein, a new biologically active compound, a 3-pyrrolin-2-one derivative – KOH-1 was synthesized. This compound is at the preclinical research stage now. The aim of this work was the development of methods for determination of KOH-1 in urine by high performance liquid chromatography (HPLC), the study of excretion KOH-1 from the organism of laboratory animals. Materials and methods. Studies on the development of methods were carried out by using a liquid chromatograph LC-20 Prominence (Shimadzu, Japan) with a diode-array detector. The validation was carried out in accordance with the requirements for bioanalytical methods, in terms of selectivity, linearity, precision and accuracy. The study of excretion of KOH-1 was performed on white non-linear male rats weighing 300-400 g. The substance KOH-1 was administered once orally in a suspension of starch mucus at a dose of 100 mg/kg. Results and discussion. As a result of the research, the method for determining the biologically active compound KOH-1 in urine has been developed. The validation showed its suitability for pharmacokinetic studies. The data on daily excretion of KOH-1 in urine after a single oral administration to rats were obtained. Conclusion. The developed conditions for the chromatographic determination of KOH-1 in urine can be used in pharmacokinetic studies, both at the preclinical and clinical stages of the study of a potential drug. The data on excretion of KOH-1 will allow to determine the ways of excretion of the preparation, and also to select a rational dosage, to identify possible contraindications to the use.

The ultrasound-promoted one-pot multicomponent synthesis of substituted 3-pyrrolin-2-ones using citric acid as a green additive in a green solvent is reported. Citric acid catalyzed the reaction efficiently without the need for any other harmful organic reagents. Clean reaction profile, easy work-up procedure, excellent yields and short reaction times are some remarkable features of this method. The utilization of ultrasound irradiation makes this method potentially very useful, fast, clean and convenient.

Rotational correlation times of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label with respect to heme and nonheme proteins

Noncovalent spin labeled proteins (ovalbumin, bovine serum albumin, hemoglobin, and cytochrome c) were investigated in order to follow the different type of interactions between the nitroxide radical of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label and functional groups of heme and nonheme proteins as well as the pH influence on molecular motion of the label with respect to these proteins. EPR spectra were recorded at room temperature and the computer simulation analysis of spectra was made in order to obtain the magnetic parameters. Noncovalent labeling of proteins can give valuable information on the magnetic interaction between the label molecule and the paramagnetic center of the proteins. The relevance of this interaction can be obtained from line shape analysis: computer simulations for nonheme proteins assume a Gaussian line shape, whereas for heme proteins, a weighted sum of Lorentzian and Gaussian components is assumed. In the framework of the moderate jump diffusion model for rotational diffusion, the rotational correlation time is strongly influenced by pH, because of the electrostatic interactions and hydrogen bonding.

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 129946-88-9. Formula: https://www.ambeed.com/products/129946-88-9.html.
