Tang, Jinghua published the artcileChemoselective Cross-Coupling between Two Different and Unactivated C(aryl)-O Bonds Enabled by Chromium Catalysis, SDS of cas: 86-51-1, the main research area is aryl methyl ether imino aryl ester chromium cross coupling; biaryl preparation.

We report here the first example of cross-coupling between two different and unactivated C(aryl)-O bonds with chromium catalysis. The combination of a low-cost Cr(II) salt, 4,4′-di-tert-butyl-2,2′-dipyridyl (dtbpy) as the ligand, and magnesium as the reductant shows high reactivity in promoting the reductive cross-coupling of aryl Me ether derivatives with aryl esters by cleavage and coupling of two different C(aryl)-O bonds under mild conditions. The formation of active low-valent Cr species by reduction of CrCl2 with Mg can be considered, which prefers to initially activate the C(aryl)-O bond of Ph Me ether with the chelation help of dtbpy and an o-imine auxiliary. The subsequent consecutive reduction, second C(aryl)-O activation, and reductive elimination allow for the achievement of selective cross-coupling of C(aryl)-O/C(aryl)-O bonds.

Borges, Igor D. published the artcileSynthesis and molecular modeling study of two bromo-dimethoxybenzaldehydes, Application of 2,3-Dimethoxybenzaldehyde, the main research area is bromo dimethoxybenzaldehyde preparation mol modeling.

This work describes the synthesis, mol. structure, and packaging of the compounds 6-bromo-2,3-dimethoxybenzaldehyde (6-BRB) and 5-bromo-2,3-dimethoxybenzaldehyde (5 BRB). Characterization in the solid-state was carried out by X-ray diffraction, and the anal. of the interactions was described by the Hirshfeld surface, which helps in understanding the effect of replacing the bromine position in the aromatic ring. Both compounds (6-BRB and 5-BRB) crystallized in the space group P21/c and are stabilized with C-HO interactions, but only the 6-BRB has a halogen-type interaction. Theor. calculations, carried out by the d. functional theory at the CAM-B3LYP/6-311++G(d,p) level of theory in gas phase, provided information on their electronic properties. The geometric properties were compared to exptl. data, and the analyses of the frontier MOs and the mol. electrostatic potential (MEP) maps were obtained to predict the phys.-chem. properties. The supramol. arrangements were analyzed throughout complexation interactions and corrected by counterpoise method. Hyperconjugation energies were employed to examine the stability of the intermol. interactions of the compounds The interaction intensities were determined through the topol. parameters obtained through the quantum theory of atoms in mols. model.

Hu, Wenbin published the artcileHeavy-atom-free charge transfer photosensitizers: Tuning the efficiency of BODIPY in singlet oxygen generation via intramolecular electron donor-acceptor interaction, Computed Properties of 86-51-1, the main research area is heavy atom charge transfer photosensitizer Boron dipyrromethenes; intramol electron donor acceptor.

To test the tunability of charge transfer (CT)-based BODIPY photosensitizers in generating singlet oxygen (1Δg), twelve meso-phenyl-BODIPY (donor-acceptor) type compounds have been synthesized and fully characterized, in which the Ph moiety is modified with resp. 0, 1, 2 and 3 methoxy groups to increase its electron-donating ability. The UV-Vis absorption spectra, fluorescence emission spectra, fluorescence quantum yield, fluorescence lifetime, excited triplet state formation, and singlet oxygen formation properties are measured. DFT quantum chem. computation is also carried out to explain the experiments The occurrence of intra-mol. CT is confirmed by UV-Vis absorption, fluorescence properties and quantum chem. computation. The triplet excited state formation is evidenced by laser radiation flash photolysis technique. The quant. photosensitized singlet oxygen formation is demonstrated by DPBF (diphenylisobenzofuran) chem. trapping method. This type of BODIPY CT photosensitizers show good tunability in generating singlet oxygen (1Δg). When the number of methoxy group on the donor is increased (so that CT is enhanced), the efficiency of singlet oxygen generation becomes higher from 0.070 to 0.30. When solvent polarity is increased (CT is also enhanced), the efficiency of singlet oxygen generation is also increased significantly. The increase in singlet oxygen generation is accompanied by the decrease in fluorescence quantum yield and fluorescence lifetime values. These facts show that a higher CT efficiency in a simple phenyl-BODIPY donor-acceptor conjugate can lead to significant higher quantum yield of singlet oxygen generation. These results are useful in designing novel CT-based heavy-atom-free photosensitizers for photodynamic therapy of tumor.

Singh, Manvendra published the artcileBroad assessment of bioactivity of a collection of spiroindane pyrrolidines through “”cell painting””, Formula: C9H10O3, the main research area is spiroindane pyrrolidine bioactivity cell painting; Biological activity; Complexity; Fingerprints; Photochemistry.

A collection of small mols. has been synthesized by composing photo-cycloaddition, C-H functionalization, and N-capping strategies. Multidimensional biol. fingerprints of mols. comprising this collection have been recorded as changes in cell and organelle morphol. This untargeted, phenotypic approach allowed for a broad assessment of biol. activity to be determined Reproducibility and the magnitude of measured fingerprints revealed activity of several treatments. Reactive functional groups, such as imines, dominated the observed activity. Two non-reactive candidate compounds with distinct bioactivity fingerprints were identified, as well.

Shalaby, Raed published the artcileSAR and molecular mechanism studies of monoamine oxidase inhibition by selected chalcone analogs, Computed Properties of 86-51-1, the main research area is monoamine oxidase chalcone; Monoamine oxidase; chalcone; dopamine; mRNA; reversibility.

The present study describes the synthesis of a series of 22 chalcone analogs. These compounds were evaluated as potential human MAO-A and MAO-B inhibitors. The compounds showed varied selectivity against the two isoforms. The IC50 values were found to be in the micromolar to submicromolar range. The Ki values of compound 16(I) were determined to be 0.047 and 0.020 μM for the inhibition of MAO-A and MAO-B, resp. Dialysis of enzyme-inhibitor mixtures indicated a reversible competitive mode of inhibition. Most of the synthesized chalcone analogs showed a better selectivity toward MAO-B. However, introducing of 2,4,6-trimethoxy substituents on ring B shifted the selectivity toward MAO-A. In addition, we investigated the mol. mechanism of MAO-B inhibition by selected chalcone analogs. Our results revealed that these selected chalcone analogs increased dopamine levels in the rat hepatoma (H4IIE) cells and decreased the relative mRNA expression of the MAO-B enzyme.

Jiang, Liping published the artcileDiscovery and evaluation of chalcone derivatives as novel potential anti-Toxoplasma gondii agents, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is chalcone diphenyl propanone preparation Toxoplasma gondii antiparasitic SAR; AI-based drug design; Antiparasitic agents; Chalcone derivatives; Structure-activity relationship; Toxoplasma gondii.

Due to numerous side effects of traditional treatments for toxoplasmosis, it is urgent to develop new anti-Toxoplasma agents with high efficiency and low toxicity. In this study, using drug-food-homologous chalcone skeleton as a leading compound, 6 series of chalcone derivatives were designed, synthesized, and almost 1/2 compounds have good anti-Toxoplasma activity in vitro. The quant. structure-activity relationship model of the anti-Toxoplasma activity of the second batch of compounds was established by random forest method (R2 = 0.9407). The Michael receptor in the mol. skeleton of chalcones plays an important role in improving the activity. Among these compounds, four chalcone derivatives exhibited potent anti-T. gondii activity and low cytotoxicity in vitro. Specifically, 1-(4-aminophenyl)-3-(3,4-dichlorophenyl)propan-1-one, (E)-3-(3,4-dichlorophenyl)-1-(4-(isopropylamino)phenyl) prop-2-en-1-one and 1-(3-aminophenyl)-3-(2,3-dimethoxyphenyl)propan-1-one derivatives effectively inhibited the proliferation of Toxoplasma tachyzoites in vivo. Liver and spleen index and biochem. parameters, such as alanine aminotransferase, aspartate aminotransferase and malondialdehyde were significantly decreased by the three chalcone derivatives, suggesting that they have protective effects on the liver of mice infected with Toxoplasma tachyzoites. Overall, this article provides a series of promising compounds for the development of anti-Toxoplasma agents.
