A pyridine-pyrazole-pyrene-based chemosensor,L, has been developed and fully characterized by all the possible techniques (ESI-MS, NMR, CHN, IRetc.). It has been found that the probe,L, selectively recognizes Cu(2+)ion and Fe(3+)ion fluorogenically and chromogenically, respectively, among a wide range of competitive metal ions. It has been demonstrated that the probe is not only metal ion-selective but also oxidation state-selective for Fe(3+)ions. The metal complexes (Cu and Fe) of the ligand were synthesized and characterized using different spectroscopic techniques and they were also characterised X-ray structurally as well, which confirm the stoichiometry (L : M = 2 : 1). The sensitivities for the fluorogenic sensing of Cu(2+)ions and chromogenic sensing of Fe(3+)have been found to be as low as nano molar level detection (69 nM and 27 nM, respectively). Further studies reveal that the Cu(II)L(2)complex can act as a turn-off fluorescent chemosensor for S(2-)ions and Fe(III)L(2)can act as a reversible turn-off colorimetric chemosensor for F(-)ions over other anions.

Two new coordination complexes of Cu(ii) viz.; [Cu(bpy)(2)(NO3)]NO3 center dot 5H(2)O (1) and [Cu(phen)(Hdmpz)Cl-2]center dot H2O (2) (bpy = 2,2 ‘-bipyridine, phen = 1,10-phenanthroline, Hdmpz = 3,5-dimethyl pyrazole) have been synthesized and characterized by single crystal X-ray diffraction, electronic spectroscopy, EPR, FT-IR spectroscopy and TGA. The nitrate anion and the water molecules in the lattice of 1 are involved in the formation of unconventional infinite supramolecular crown-like nitrate-water clusters. The unconventional enclathration of guest cationic complex moieties of 1 within the supramolecular nitrate-water crown hosts provides stability to the crystal structure. Crystal structure analysis of 2 reveals the presence of cooperative ternary pi-stacked assemblies with enclathration of single guest water molecules in hexameric Cu(II) supramolecular host cavities. Theoretical calculations have been performed to analyse the non-covalent interactions in the compounds; focusing on the unusual H-bonding network/anion-pi cooperative assemblies in 1 and two different pi-stacked cooperative assemblies in 2. DFT studies reveal that the distribution and orientation of the H-bonds in the cooperative H-bonding network in 1 is the most favoured. The high interaction energies of (pi-pi)(1) and (pi-pi)(2) in pi-stacked ternary assemblies of 2 can be attributed to the participation of the entire aromatic surfaces with antiparallel orientations and the cooperative C-H center dot center dot center dot Cl interactions respectively. The in vitro antiproliferative activities of the compounds considering cell cytotoxicity, apoptosis and DNA fragmentation assays reveal significant concentration dependent cytotoxicity in DL cancer cells with nominal effects in normal PBMC cells. The molecular docking and pharmacophore studies established the structure activity relationship of the compounds.

Using TiOⁱPr4 with a pyrazole ligand for one-pot LA polymerization improved catalytic activity compared with using TiOⁱPr4 only. At 60 degrees C, TiOⁱPr4 with ^furPz exhibited a higher catalytic activity (approximately 3-fold) than TiOⁱPr4. At room temperature, TiOⁱPr4 with ^BuPz exhibited a higher catalytic activity (approximately 17-fold) than TiOⁱPr4. High molecular mass PLA (MnGPC = 51 100, and D = 1.10) could be produced by using TiOⁱPr4 with ^furPz in melt polymerization ([TiOⁱPr4] : [^furPz] = 1000 : 1 : 1 at 100 degrees C, 240 min). The crystal structure of ^MePz2Ti2OⁱPr7 revealed the cooperative activation between two Ti atoms during LA polymerization.

Quality Control of 3,5-Dimethyl-1H-pyrazole. I found the field of Polymer Science very interesting. Saw the article Synthesis of blocked waterborne polyurethane with 3,5-dimethylpyrazole for industrial application in digital inkjet printing published in 2019.0, Reprint Addresses Wang, XM (corresponding author), Sun Yat Sen Univ, Minist Educ, Sch Chem, Key Lab Polymer Composite & Funct Mat, Guangzhou 510275, Guangdong, Peoples R China.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

In this article, a series of blocked waterborne polyurethanes (BWPUs) were synthesized by isophorone diisocyanate, polyols, dimethylol butanoic acid (DMBA), and 3,5-dimethylpyrazole. BWPUs were applied to digital inkjet printing of textiles. The successful synthesis and deblocking of BWPU were confirmed by Fourier transform infrared spectroscopy and differential scanning calorimetry. The colorfastness was improved by deblocking the terminal NCO groups at 140 degrees C, which could react with fiber. This article presented a characterization method of filtering rate to evaluate the fluency of inkjet printing. Besides, the digital microscope was used to investigate the pigment transferred to the white test cloth. In the end, we chose poly(ethylene glycol adipate) 2000 as the polyol, 1,4-butanediol as the chain extender, 1.6 as the NCO/OH molar ratio, and 4% as the mass fraction of DMBA.

The study of the relationship between intermolecular interactions present in the solvation process and the magnitude of thermodynamic properties is extended from imidazole to pyrazole derivatives. The enthalpies of solution of pyrazole, 3,5-dimethylpyrazole and 3,4,5-trimethylpyrazole were calorimetrically determined in the solvents water, methanol and acetonitrile. The enthalpy of solution values for the three compounds in the three solvents are endothermic and spontaneous with an increase in entropy. As in the case with imidazole derivatives, the formation of a solution of pyrazole derivatives creates liquids that are more structured thermodynamically. The enthalpy of sublimation for 3,4,5-trimethylpyrazole, which is not available in the literature, was determined by the Knudsen effusion method. The combination of these thermodynamic properties has allowed the corresponding enthalpies of solvation to be obtained for the three pyrazole derivatives in the three selected solvents. With the use of the Pierotti equations and the enthalpies of solvation, the enthalpies of cavity formation were calculated along with the corresponding solute-solvent enthalpies of interaction. The infrared spectra and molecular volumes, as estimated through the electronic density, were used to obtain molecular insights into the solvation sensible sites within the studied solute molecules. The discussion of the solvation process and enthalpies of interaction of the pyrazole derivatives is based on the molecular structural features of solutes, specific intermolecular interactions and protic or aprotic nature of the solvents. The use of any empirical parameters in the discussion of the results was avoided. (C) 2020 Elsevier B.V. All rights reserved.

Objective. Exposure to severe stressors may alter immune function and augment inflammation and cytokine release, increasing risk of autoimmune disease. We examined whether childhood abuse was associated with a heightened risk of incident systemic lupus erythematosus (SLE). Methods. Data were drawn from the Nurses’ Health Study II, a cohort of US female nurses enrolled in 1989, followed with biennial questionnaires. We measured childhood physical and emotional abuse with the Physical and Emotional Abuse Subscale of the Childhood Trauma Questionnaire and sexual abuse with the Sexual Maltreatment Scale of the Parent-Child Conflict Tactics Scale, both administered in 2001. We identified incident SLE (>= 4 American College of Rheumatology 1997 classification criteria) through 2015. We used multivariable Cox regression models to evaluate the association between childhood abuse and SLE, accounting for potential confounders (e.g., parental education, occupation, home ownership) and mediators [e.g., depression, posttraumatic stress disorder (PTSD)]. Results. Among 67,516 women, there were 94 cases of incident SLE. In adjusted models, exposure to the highest versus lowest physical and emotional abuse was associated with 2.57 times greater risk of SLE (95% CI 1.30-5.12). We found that 17% (p < 0.0001) of SLE risk associated with abuse could be explained by depression and 23% (p < 0.0001) by PTSD. We did not observe a statistically significant association with sexual abuse (HR 0.84, 95% CI 0.40-1.77, highest vs lowest exposure). Conclusion. We observed significantly increased risk of SLE among women who had experienced childhood physical and emotional abuse compared with women who had not. Exposure to childhood adversity may contribute to development of SLE. SDS of cas: 67-51-6.

A butterfly-shaped dinuclear Pt(II) complex having pyridyl-NHC chelate ligands and bridging Me(2)pz ligands was synthesized. The crystal structure of the Pt-2 complex showed short intramolecular Pt center dot center dot center dot Pt distance (3.129 angstrom) and unique packing structure containing one-dimensional infinite pore that was filled with solvent molecules. The absorbance was proportional to the concentration of Pt-2 complex and no significant bands appeared even in high concentration (up to 100 mu M). The Pt-2 complex showed bluish-green emission (lambda(max) = 459 nm) in the solid state at 298 K (lambda(ex) = 330 nm). TD-DFT calculation revealed that the lowest-energy absorption bands are mainly assigned to the combination of metal-to-ligand charge transfer (MLCT) and ligand-to-ligand charge transfer (LLCT) transitions.

Two unexpected one-dimensional coordination polymers, [Cu(PT)(H2O)Cl](n) 1 and [Cu-2(BPT)(ClO4)(3)(H2O)(4)](n)center dot 2nH(2)O 2, of symmetrical triazine-based ligands were synthesized by Cu(II)-mediated hydrolysis of the 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (MBPT) pincer ligand. The reaction of Cu(ClO4)(2)center dot 6H(2)O with MBPT proceeded via hydrolysis of the methoxy group to produce the dicompartmental 4,6-bis(3,5-dimethyl-1H-pyrazol-1-yl)-1,3,5-triazin-2(1H)-one ligand (HBPT) that then undergoes in situ complexation with Cu(II) to afford 2. In case of CuCl2, the reaction proceeds further with C-N cleavage of one pyrazolyl unit leading to the formation of 6-(3,5-dimethyl-1H-pyrazol-1-yl)-1,3,5-triazine-2,4(1H,3H)-dione ligand (HPT) that also undergoes in situ complexation with Cu(II) affording 1. The role of Cu(II) is to increase the Lewis acid reactivity of the water molecule where similar hydrolytic reactions for MBPT were observed in acidic medium in presence of an aqueous HCl (1:1 v/v) solution. The molecular and supramolecular structures of complexes 1 and 2 were investigated using X-ray diffraction of single crystal, Hirshfeld analysis, and density functional theory calculations. The Cl center dot center dot center dot H (11.7%) and O center dot center dot center dot H (24.7%) contacts are the most important in 1, whereas the molecular packing of 2 is controlled mainly by the O center dot center dot center dot H (58.7%) hydrogen bonds. Complex 2 showed better activity against Escherichia coli, Bacillus subtilis, and Candida albicans compared with the standard antibiotics amoxicillin, tetracycline, and ampicillin. In general, complexes 1 and 2 showed good antimicrobial activity than these antibiotics and have the advantage to be used as both antibacterial and antifungal agents.
