To the fast calculation of the solvation free energy. Combining expanded ensembles with L2MC

A more efficient version of the Expanded Ensembles method for calculation of free energy in molecular-mechanical simulations is proposed. The method is based on the Horowitz L2MC approach to accelerate movement along the alchemical coordinate. It is possible to achieve the same efficiency of the algorithm both with the optimal number of windows and with a larger number of them compared to the original algorithm. Since the optimal number of windows is unknown a priory, the proposed algorithm is more robust than the traditional one. We can choose the number of windows in excess and do not worry about the loss of efficiency. We illustrate the method’s efficiency with the computation of the hydration free energies of pyridine and water.

DFT insights in to the hydrodenitrogenation behavior differences between indole and quinoline

The hydrodenitrogenation behavior differences between indole and quinoline were investigated using density functional theory calculation to explain the phenomena of previous experimental results. Theoretical calculation was carried out to explain the results using GGA-RPBE function with dispersion force correlation. The process of hydrogenation of indole, quinoline and 1,2,3,4-tetrahydroquinoline as well as denitrogenation of o-ethylaniline and o-propylaniline were conducted on a NiMoS nanocluster. The results suggest Ni-S-Edge is suitable for hydrogenation saturation of aromatic rings of nitrogen compounds and Ni-Mo-Edge is responsible for hydrogenolysis of C-N bond via E2 path. Besides, indoline could be directly converted to o-ethylaniline, whereas the C-N bond of 1,2,3,4-tetrahydroquinoline could only be broken after complete saturation of the aromatic ring. The reason is that the N atom and C=C bond of indoline could be coplanar and well adsorbed on Ni-Mo-Edge simultaneously, which is beneficial to reduce the activation energy of C-N bond cleavage.

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 24242-20-4. HPLC of Formula: C6H6N2O2.

Synthesised spirobichroman-based polyimide functionalized by pyridine: Effects of substituent position on gas separation and thermal properties

Spirobichroman-based polymers have garnered considerable attention as promising gas separation membrane materials. Herein, two spirobichroman-based diamines were synthesised using a pyridine heterocyclic ring with methyl substituents at different positions. The diamines were reacted with 4,4 ‘-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and bis-(3-phthalyl anhydride) ether (ODPA) to achieve four polyimides functionalised by pyridine. The polymers performances were characterised by experimentally and molecular dynamics simulations. They showed high molecular weights of M-n = 9.4 to 14.0 x 10(4), excellent thermal stability, good solubility in a series of common organic solvents, and easy processability to form membranes. The membrane showed high gas pair selectivities of alpha CO2/CH4>30 and alpha CO2/N2>24, which were attributed to turnstile-like rotary motions of the methyl and basic group of pyridine. The gas permeability results suggested that the substituents position of the methyl has little effect on the rigid molecular chain, unlike the densely packed flexible molecules chains.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 24242-20-4, in my other articles.

Design, synthesis, spectral characterization and molecular docking studies of novel pyranoquinolinyl dihydropyridine carboxylates as potential antibacterial agents including Vibrio cholerae with minimal cytotoxity towards fibroblast cell line (L-929)

Novel pyranoquinolinyl dihydropyridine carboxylate (PDC) derivatives were designed by incorporating the multi-drug resistance modulating effects of 1,4 dihydropyridines along with potential antibacterial activity of quinolines in the molecular design. The designed PDC derivatives were synthesized by multi-step synthesis involving Michael addition, reduction followed by inverse electro demand Diels-Alder reaction to produce pyranoquinolinyl dihydropyridine carboxylates in good yields. All the PDC derivatives were characterized by H-1 NMR, C-13 NMR, FT-IR, Mass spectral and CHN analysis. The Quinolinyl dihydropyridine carboxylate derivatives were evaluated for in vitro antibacterial activity by agar well diffusion method. Molecular docking studies revealed that the exo diethyl 4-(4aR,58,10bR)-5-(4-chlorophenyl)-3,4,4a,5,6,10b-hexahydro-2H-pyrano [3,2-c] quinolin-8-yl) 2,6 dimethyl-1,4-dihydropyridine-3,5-dicarboxylate diastereomer (5c) forms four hydrogen bonds with the cell wall protein of vibrio cholerae in comparison to the endo diethyl 4-((4aR,5R,10bR) 5 (4 chloropheny1)-3,4,4a,5,6,10b-hexahydro-2H-pyrano [3,2-c] quinolin-8-yl)-2,6-dimethyl-1, 4-dihydro pyridine-3,5- dicarboxylate diastereomer (4c) which forms two hydrogen bonds with the cell wall protein of vibrio cholerae and hence leading to better anchorage, enhanced gold score and relatively good antibacterial activity for the exo PDC derivatives. Minimum inhibitory concentration (MIC) of the active compounds was evaluated by macro dilution method. The mechanism of antibacterial action of the PDC derivatives was investigated by SEM studies. The cytotoxicity of PDC derivatives were evaluated against fibroblast cells (L-929).

Synthesis, characterization and surface enhanced Raman spectroscopy study of a new family of different substituted cruciform molecular systems deposited on gold nanoparticles

In this work, the adsorption and orientation on gold nanoparticles (AuNps) of a new family of cruciform systems consisting of thiophene rings and imino groups were studied. The structural modification and its influence on the adsorbate-substrate interaction were evaluated by UV-Vis spectroscopy and Surface Enhanced Raman Spectroscopy (SERS). The absence of SERS spectrum for (N,N ‘-bis(4-(trifluoromethyl)benzylidene)-2,5-di (thiophene-2-yl)-1,4-diaminobenzene) CFF shows that the inclusion of a trifluoromethyl group (-CF3) on the benzylidene fragment limits the interaction of the CFF system with the gold substrate, in contrast, to that obtained for (N, N ‘-dibenzylidene-2,5-di (thiophene-2-yl) -1,4-diaminobenzene) 2-CF and (N, N ‘-bis (4-methoxybenzylidene) -2,5-di (thiophene-2yl) -1,4-diaminobenzene) CMF, where the adsorption took place preferentially through the thiophene rings, resulting in partial quinoidization. On the other hand, the interaction for compound (N, N ‘-bis (4-methylenepyridinyl) -2,5-di (thiophene-2-yl) -1,4-diaminobenzene) CPy with the surface was conducted by means of the pyridinic fragments. The systematic modification of the bifunctional cruciform systems, with groups of different nature, makes it possible to rationalize the structural aspects that directly influence the adsorbate-substrate interaction and molecular orientation on gold substrates. These structural parameters are the basis to the development of stable molecular assemblies, which can act as basic building blocks in the manufacture of molecular switches.
