Metal-Free Synthesis and Photophysical Properties of 1,2,4-Triarylpyrroles

A three-component reaction has been developed for the construction of multiaryl-substituted pyrrole derivatives from arylketones, amines, and nitrovinylarenes under metal- free conditions. Hence, homologous 1,2,4-triaryl-substituted pyrrole products were obtained in good to high yields. Furthermore, 2,3,5-triaryl-substituted pyrroles were selectively formed in the absence of nitrovinylarenes. The photophysical properties of some pyrrole products have been investigated to show good aggregation-induced emission (AIE) activity.

Electric Literature of 90-52-8, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 90-52-8.

Heterocyclic Ring-Opening of Nanographene on Au(111)

Cyclo-dehydrogenation is of importance to induce the planarization of molecules on noble surfaces upon annealing. In contrast to a number of successful syntheses of polycyclic aromatic hydrocarbons by forming carbon-carbon bonds, it is still rare to conduct conjugation and cleavage of carbon-nitrogen bonds in molecules. Here, we present a systematic transformation of the C-N bonds in11,11,12,12-tetraphenyl-1,4,5,8-tetraazaanthraquinodimethane as well as three other derivatives on Au(111). With bond-resolved scanning tunneling microscopy, we discovered novel the heterocyclic segregation reaction of one pyrazine ring with two nitrogen atoms to form two quinoline rings with one nitrogen each. Density functional theory calculations showed that the intramolecular ring-forming and -opening of N-heterocycles are strongly affected by the initial hydrogen-substrate interaction.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 90-52-8. Safety of 8-Amino-6-methoxyquinoline.

Crystal structure, Hirshfeld surface analysis, DFT and molecular docking investigation of 2-(2-oxo-1,3-oxazolidin-3-yl)ethyl 2-[2-(2-oxo-1,3-oxazolidin-3-yl)ethoxy]quinoline-4-carboxylate

In the molecular structure of the title compound, C20H21N3O7, the quinoline ring system is slightly bent, with a dihedral angle between the phenyl and the pyridine rings of 3.47 (7)degrees. In the crystal, corrugated layers of molecules extending along the ab plane are generated by C-H center dot center dot center dot O hydrogen bonds. The intermolecular interactions were quantified by Hirshfeld surface analysis and two-dimensional fingerprint plots. The most significant contributions to the crystal packing are from H center dot center dot center dot H (42.3%), H center dot center dot center dot O/O center dot center dot center dot H (34.5%) and H center dot center dot center dot C/C center dot center dot center dot H (17.6%) contacts. Molecular orbital calculations providing electron-density plots of the HOMO and LUMO as well as molecular electrostatic potentials (MEP) were computed, both with the DFT/B3LYP/6-311 G++(d,p) basis set. A molecular docking study between the title molecule and the COVID-19 main protease (PDB ID: 6LU7) was performed, showing that it is a good agent because of its affinity and ability to adhere to the active sites of the protein.

Synthesis of fluorescent nanoprobe with simultaneous response to intracellular pH and Zn2+ for tumor cell distinguishment

A novel dual-functional nanoprobe was designed and synthesized by facile assembly of quinoline derivative (PEIQ) and meso-tetra (4-carboxyphenyl) porphine (TCPP) via electrostatic interaction for simultaneous sensing of fluorescence of Zn2+ and pH. Under the single-wavelength excitation at 400 nm, this nanoprobe not only exhibits OFF-ON green fluorescence at 512 nm by specific PEIQ-Zn2+ chelation, but also presents red fluorescence enhancement at 654 nm by H+-triggered TCPP release. The nanoprobe demonstrated excellent sensing performance with a good linear range (Zn2+, 1-40 mu M; pH, 5.0-8.0), low detection limit (Zn2+, 0.88 mu M), and simultaneous response towards Zn2+ and pH in pure aqueous solution within 2 min. More importantly, this dual-functional nanoprobe demonstrates the capability of discerning cancerous cells from normal cells, as evidenced by the fact that cancerous HepG2 cells in tumor microenvironment exhibit substantially higher red fluorescence and significantly lower green fluorescence than normal HL-7702 cells. The simultaneous, real-time fluorescence imaging of multiple analytes in a living system could be significant for cell analysis and tracking, cancer diagnosis, and even fluorescence-guided surgery of tumors.Graphical abstract

Diversification of quinoline-triazole scaffolds with CORMs: Synthesis, in vitro and in silico biological evaluation against Plasmodium falciparum

A discrete series of tricarbonyl manganese and rhenium complexes conjugated to a quinoline-triazole hybrid scaffold were synthesised and their inhibitory activities evaluated against Plasmodium falciparum. In general, the complexes show moderate activity with improved inhibitory activities for the photoactivatable manganese(I) tricarbonyl complexes in the malaria parasite. All complexes are active in the dark against the NF54 CQS (chloroquine-sensitive) and K1 MDR (multidrug-resistant) strains of Plasmodium falciparum, with IC50 values in the low micromolar range. Of significance, the complexes retain their activity in the MDR strain with resistance indices ranging between 1.1 and 2.1. The Mn(I) analogues display photodissociation of all three CO ligands upon irradiation at 365 nm. More importantly, the complexes show increased antimalarial activity in vitro upon photoactivation, something not observed by the clinically used reference drug, chloroquine. As a purported mechanism of action, the compounds were evaluated as beta-haematin inhibitors. To further understand the interactions of the complexes, in silico hemozoin docking simulations were performed, attesting to the fact that CO-release could be vital for blocking the hemozoin formation pathway. These results show that this strategy may be a valuable, novel route to design antimalarial agents with higher efficacy.

Discovery of 4-((4-(4-(3-(2-(2,6-difluorophenyl)-4-oxothiazolidin-3-yl)ureido)-2-fluorophenoxy)-6-methoxyquinolin-7-yl)oxy)-N, N-diethylpiperidine-1-carboxamide as kinase inhibitor for the treatment of colorectal cancer

In this study, a novel series of 4,6,7-trisubstituted quinoline analogues bearing thiazolidinones were designed and synthesized based on our previous study. Among them, the most potent compound 15i, 4-((4-(4-(3-(2-(2,6-difluorophenyl)-4-oxothiazolidin-3-yeureido)-2-fluorophenoxy)-6-methoxyquinolin-7-yl)oxy)-N,N-diethylpiperidine-1-carboxamide was identified as a multi-kinase inhibitor. The results of MTT assay revealed in vitro antitumor activities against HT-29 cells of compound 15i with an IC50 value of 0.19 mu M which was 14.5-fold more potent than that of Regorafenib. In the cellular context, significant antiproliferation, cytotoxicity and induction of apoptosis on HT-29 cells in a dose- and time-dependent manner were confirmed by IncuCyte live-cell imaging assays. Moreover, compound 15i strongly induced apoptosis by arresting cell cycle into the G2/M phase. No antiproliferation and cytotoxicity against human normal colorectal mucosa epithelial cell FHC was observed at 10.0 mu g/mL or lower concentrations which indicated that the toxicity to normal cells of compound 15i was much lower than that of Regorafenib. Based on the above findings, further structural modification will be conducted for the development of more potent kinase inhibitors as anticancer agents.
