Supramolecular Switching Surface for Antifouling and Bactericidal Activities

Antibacterial materials are often bothered by the problems of drug-resistance-induction and adhesion-to-invalidation, coming from the exposure of reusable bactericidal materials before or after utilization. Herein, an efficient and easily transformable supramolecular switching surface for antifouling and bactericidal was successfully fabricated, through introducing a negatively charged macrocyclic host S6-corona[3]arene[3]pyridazine (S6-CAP) to a contact-killing surface constructed by a positively charged amphiphilic bactericide. The S6-CAP was able to fully switch off the bactericidal activity and make the surfaces antifouling. After switched on by simply washing off much of S6-CAP, the bactericidal activity was even better than the original contact-killing surfaces.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 375-72-4 help many people in the next few years. Quality Control of 1,1,2,2,3,3,4,4,4-Nonafluorobutane-1-sulfonyl fluoride.

Novel pyrazoles and pyrazolo[1,2-a]pyridazines as selective COX-2 inhibitors; Ultrasound-assisted synthesis, biological evaluation, and DFT calculations

COX-2 is an inducible enzyme mediating inflammatory responses. Selective targeting of COX-2 is useful for developing anti-inflammatory agents devoid of ulcerogenic activity. Herein, we report the design and synthesis of a series of pyrazoles and pyrazolo[1,2-a]pyridazines with selective COX-2 inhibitory activity and in vivo anti-inflammatory effect. Both series were accessed through acid-catalyzed ultrasound assisted reactions. The most active compounds in this study are two novel molecules, 11 and 16, showing promising selectivity and decent IC50 of 16.2 and 20.1 nM, respectively. These compounds were also docked into the crystal structure of COX-2 enzyme (PDB ID: 3LN1) to understand their mode of binding. Finally, Mulliken charges and electrostatic surface potential were calculated for both compound 11 and celecoxib using DFT method to get insights into the molecular determinants of activity of this compound. These results could lead to the development of novel COX-2 inhibitors with improved selectivity. (C) 2017 Elsevier Ltd. All rights reserved.

Crystal structure, Hirshfeld surface analysis and DFT studies of 6-[(E)-2-(thiophen-2-yl)etnenyl]-4,5-dihydropyridazin-3(2H)-one

In the title compound, C10H10N2OS, the five atoms of the thiophene ring are essentially coplanar (r.m.s. deviation = 0.0037 angstrom) and the pyridazine ring is nonplanar. In the crystal, pairs of N-H center dot center dot center dot O hydrogen bonds link the molecules into dimers with an R-2(2)(8) ring motif. The dimers are linked by C-H center dot center dot center dot O interactions, forming layers parallel to the be plane. The theoretical geometric parameters are in good agreement with XRD results. The intermolecular interactions were investigated using a Hirshfeld surface analysis and two-dimensional fingerprint plots. The Hirshfeld surface analysis of the title compound suggests that the most significant contributions to the crystal packing are by H center dot center dot center dot H (39.7%), C center dot center dot center dot H/H center dot center dot center dot C (17.3%) and O center dot center dot center dot H/H center dot center dot center dot O (16.8%) contacts.

Synthesis of Pyridazine Derivatives by Suzuki-Miyaura Cross-Coupling Reaction and Evaluation of Their Optical and Electronic Properties through Experimental and Theoretical Studies

A series of -conjugated molecules, based on pyridazine and thiophene heterocycles 3a-e, were synthesized using commercially, or readily available, coupling components, through a palladium catalyzed Suzuki-Miyaura cross-coupling reaction. The electron-deficient pyridazine heterocycle was functionalized by a thiophene electron-rich heterocycle at position six, and different (hetero)aromatic moieties (phenyl, thienyl, furanyl) were functionalized with electron acceptor groups at position three. Density Functional Theory (DFT) calculations were carried out to obtain information on the conformation, electronic structure, electron distribution, dipolar moment, and molecular nonlinear response of the synthesized push-pull pyridazine derivatives. Hyper-Rayleigh scattering in 1,4-dioxane solutions, using a fundamental wavelength of 1064 nm, was used to evaluate their second-order nonlinear optical properties. The thienylpyridazine functionalized with the cyano-phenyl moiety exhibited the largest first hyperpolarizability ( = 175 x 10(-30) esu, using the T convention) indicating its potential as a second harmonic generation (SHG) chromophore.

Electrochemical, Morphological and Anti-corrosive Characteristics of Pyrazine Derivatives for Mild Steel Corrosion in Aggressive Medium: A Comparative Study

The anti-corrosive characteristics of 2,5-dimethylpyrazine (2,5-DMP) and 2,6-dimethylpyrazine (2,6-DMP) on the corrosion of mild steel in 0.5M sulfuric acid have been studied by gravimetric method and electrochemical techniques (potentiodynamic polarization, linear polarization resistance and electrochemical impedance measurement) to observe the adsorption of these pyrazine derivatives at the metal/solution interface. The results obtained have revealed that 2,5-DMP performs more efficiently in comparison with 2,6-DMP showing an efficiency of 97.12% at a concentration of 10(-2)M. The polarization curves clearly indicate that both chemicals act as a mixed-type inhibitors showing a predominance toward the cathodic reaction. Langmuir’s isotherm model was found to adequately describe the adsorption of both these inhibitors onto the mild steel surface. The calculated value of the free energy for the adsorption process, eveals a strong chemisorbed bond as well as a spontaneous adsorption process between the tested inhibitors and the mild steel surface. Surface morphological analysis of the MS specimens treated with these inhibitors has been conducted using energy-sispersive atomic X-ray spectroscopy. The results obtained have shown a good agreement with the results obtained from electrochemical techniques. Quantum chemical calculations have also been performed using hyperchem 8.0.6 package to supplement the findings from the preceding techniques.

A photochromic diarylethene-functionalized fluorescent probe for Cd2+ and Zn2+ detections

A novel bifunctional chemosensor 10 constructed with diarylethene and pyridazine unit has been designed and synthesized with excellent photochromic properties upon UV/Vis radiation. The chemosensor 10 shows prominent selectivity and high sensitivity for Cd2+ and Zn2+ by obvious fluorescent enhancement with a low detection limit in water-acetonitrile solution (v((water)):v((acetonitrile)) = 1:9). The chemosensor 10 could be utilized as a fluorescent sensor for Cd2+ with a limit of detection (LOD) of 2.3 x 10(-6) M. With the presence of Zn2+, the fluorescence of the generated zinc complex enhances remarkably and the limit of detection (LOD) for Zn2+ is calculated to be 1.1 x 10(-5) M by Job’s plot titrations. A logic circuit of this chemosensor 10 has been constructed with the input signals of UV and visible light, Cd2+ (or Zn2+) and EDTA and the output signal of the emission intensity. In addition, the concentrations of Cd2+ or Zn2+ in real water are detected quickly and conveniently by this chemosensor. (C) 2020 Elsevier Ltd. All rights reserved.

Cyclization of beta-Chlorovinyl Thiohydrazones into Pyridazines: A Mechanistic Study

Extensive experimental and theoretical investigations on the isomerization and heterocyclizations of -chlorovinyl thiohydrazones derived from oxamic acid thiohydrazides and -chlorovinyl aldehydes were performed to elucidate the reaction mechanism of pyridazine formation. We showed that model -chlorovinyl thiohydrazone undergoes multiple isomerization reactions in solution induced by thione-thiol tautomerism and Z/E-isomerization at the C=N bond. Mechanistic rationalization along with computational studies demonstrated that pyridazine is predominantly generated from the Z-thiol isomers by 6-electrocyclization of the thiohydrazone-derived 2,3-diazatriene intermediate. The autocatalytic character of cyclization accelerated by the formation of acid was demonstrated by means of H-1 NMR monitoring.

Solvent-dependent alignments and halogen-related interactions in inclusion crystals of adamantane-based macrocycle with pyridazine moieties

Halogen center dot center dot center dot halogen contacts are considerably important intermolecular interactions. An adamantane-based macrocycle with pyridazine moieties (1) was synthesized from 3,6-dichloropyridazine and disubstituted adamantane possessing chlorophenol moieties in 57% yield as a new host molecule. The crystallization of 1 in various solvents afforded six inclusion crystals. The macrocyclic framework had a nearly hexagonal structure with a cavity, and was assembled into various network structures composed of layer architectures bearing channels. In crystals containing cyclic ethers, halogen-halogen interactions between all chlorine atoms of 1 were observed. Meanwhile, in crystals containing halomethanes and aromatic compounds, CH center dot center dot center dot Cl interactions alternately and partially appeared.
