Structure-activity relationships for a series of small-molecule thiophenes resulted in potent and selective antagonism of human Complement C3a receptor. The compounds are about 100-fold more potent than the most reported antagonist SB290157. A new compound JR14a was among the most potent of the new antagonists in vitro, assessed by (a) inhibition of intracellular calcium release (IC50 10 nM) induced in human monocyte-derived macrophages by 100 nM C3a, (b) inhibition of beta-hexosaminidase secretion (IC50 8 nM) from human LAD2 mast cells degranulated by 100 nM C3a, and (c) selectivity for human C3aR over C5aR JR14a was metabolically stable in rat plasma and in rat liver microsomes and efficacious in rats when given orally to suppress rat paw inflammation, macrophage and mast cell activation, and histopathology induced by intraplantar paw administration of a C3aR agonist. Potent C3aR antagonists are now available for interrogating C3a receptor activation and suppressing C3aR-mediated inflammation in mammalian physiology and disease.

BACKGROUND Chinese rice wine (CRW) is a kind of traditional fermentation wine in China. Aged CRW is more popular among consumers owing to its harmonious and pleasant flavor. The volatile profile of CRW has been extensively studied using gas chromatography/mass spectrometry (GC/MS). However, flavor components in CRW are far richer than those detected by GC/MS. To obtain more information about the volatile profile of fresh (5-year) and aged (10-year) CRW, a method based on comprehensive two-dimensional gas chromatography coupled to quadrupole mass spectrometry (GCxGC/qMS) was developed. The major volatile compounds contributing to the characteristic aroma of fresh and aged CRW were identified by surrogate odor activity value (OAV). RESULTS Ninety-eight volatile compounds were detected in the 5-year CRW samples and 107 in the 10-year samples by GCxGC/qMS. The numbers of compounds detected by GCxGC/qMS for the 5-year and 10-year samples were 71.4 and 65.4% higher than those detected by GC/MS. The aged wine had a more complex volatile profile than the fresh wine, with an increase in esters and aldehydes and a decrease in alcohols and organic acids. There were 22 volatile compounds with surrogate OAV > 1. Nine were the potent key aroma compounds in CRW: ethyl isovalerate (OAV 500-33 500), ethyl butyrate (OAV 84-334), ethyl isobutyrate (OAV 49-170), 2-nonenal (OAV 20-100), ethyl heptanoate (OAV 1-74), ethyl hexanoate (OAV 60-77), phenylethyl alcohol (OAV 2-18), benzaldehyde (OAV 28-30) and hexanal (OAV 4-11). CONCLUSION GCxGC/qMS showed better separation than GC/MS. The presented GCxGC/qMS method was suitable for characterization of the volatile profile of CRW. (c) 2019 Society of Chemical Industry

Three new mononuclear complexes of the type [M(L)(2)](ClO4)(2), with Ni(II) (1), Cu(II) (2) and Zn(II) (3) ions, have been synthesized and structurally characterized, using the N,N,O donor Schiff base ligand 2-[(phenyl-pyridine-2-yl-methylene)-amino]-ethanol]. An X-ray diffraction study reveals identical crystallization patterns for each of the complexes, in the monoclinic crystal system with the C2/c space group. Interestingly, the synthesized complexes are isostructural in nature. The complexes showed biomimetic phenoxazinone synthase-like activity for the aerial oxidation of o-aminophenol to phenoxazine-2-one, separately in methanol (MeOH) and acetonitrile (ACN) solutions. For each of the complexes, the turnover numbers were found to be higher in MeOH than in ACN. The highest catalytic activity between among the three complexes was found to be for complex 2.

A new Schiff base receptor (2-amino-3-(((3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl)methylene) amino)maleonitrile (GAL)) has been synthesized and such diaminomaleonitrile-based molecular framework is observed to be water soluble. GAL possesses both colorimetric and off-on fluorescent response in the presence of ClO-. The response time has been controlled within 6 min. The limit of detection (LOD) has been calculated to be 47.5 nM. The addition of Cu2+ can only induce clear color evolution from pale to deep yellow (LOD: 0.22 mu M) and no fluorescence changes are found. Moreover, its reliability and practicality are verified via the determination of ClO- in spiked samples of tap water and pond water. The exploration of bioactive vitamin B6 cofactor as a sensing platform will open a new way for multiple target recognition in competitive mediums. (C) 2020 Elsevier B.V. All rights reserved.

The kinetics and mechanism of condensation of pyridoxal hydrochloride with L-alpha-asparagine, L-alpha- and D-alpha-aspartic acids are analyzed via UV spectroscopy and polarimetry. It is found that L-alpha-asparagine containing alpha-NH2 and gamma-NH2 groups interacts with pyridoxal via the gamma-NH2 group, forming Schiff bases that are resistant to chemical transformations. Rearrangement produces Schiff bases that form the cyclic structure from the amino acid moiety. L-alpha- and D-alpha-aspartic acids interacting with pyridoxal via alpha-NH2 groups create Schiff bases that form quinoid structures after elimination of alpha-hydrogen or CO2. Their subsequent hydrolysis results in pyridoxamine, alpha-ketoacids, and aldehyde acids, respectively. Schemes of the condensation mechanisms of L-alpha-asparagine, L-alpha-, D-alpha-aspartic acids with pyridoxal hydrochloride are proposed.

Herein we report, a mononuclear, highly fluorescent zinc(ii) complex Zn(L)(N-3)(H2O) (1) that was prepared by an easy one pot method, in which the tridentate Schiff base ligand (E)-4-((2-(dimethylamino)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (HL) was generated in situ. The compound is characterized by various spectroscopic techniques, and its structure was determined by single crystal X-ray diffraction studies. DFT calculations were used to understand the electronic structures of the ligand and the complex, and TD-DFT calculations were performed to interpret the nature of the electronic transitions observed in their UV-vis spectra. In the complex, Zn(II) is found to be penta-coordinated with one azide ligand, an aqua ligand and a monoanionic tridentate N,N,O-donor ligand. In an aqueous methanol (1:9 by volume) solution, at the physiological pH (0.01 M Tris-HCl buffer, pH 7.4), compound 1 exhibits an intense greenish blue fluorescence (lambda(ex) 390 nm, lambda(em) 462 nm), whose intensity is about 17-fold stronger than that of the free ligand. Compound 1 is found to show significant DNA binding activity. The pyridoxal appended tridentate ligand can be used for the bio-imaging of Zn(II).

Five new nickel(II) complexes [Ni(L)NCS] (1b), [Ni(L)N-3] (2), [Ni(L)N(CN)(2)] (3), [Ni(L)OAc] (4) and [Ni(HL)SO4] (5) of a thiosemicarbazone HL (where HL = 2-benzoylpyridine-N(4)-phenylthiosemicarbazone) including pseudohalides like thiocyanate, azide and dicyanamide have been synthesized and characterized by elemental analysis, magnetic susceptibility, FT-IR, electronic and NMR spectroscopic techniques. The interesting amido-iminol tautomerism enables the pro-ligand to exist in amido form as well as deprotonated iminol form thereby functioning as tridentate NNS donor, coordinating through pyridyl nitrogen atom, azomethine nitrogen atom and amido/iminolate sulfur atom in the complexes. The crystal structures were established by single crystal XRD analysis. Two different single crystals of the compound thiocyanato complex were obtained with and without DMF solvent molecule having triclinic and monoclinic lattices with P (1) over bar and P2(1)/n space groups respectively. Also, the compound 2 is having a monoclinic lattice with P21/n space group. Nickel(II) exists in distorted square planar geometry in all the complexes. Further DFT calculations were carried out at B3LYP/TZVP level of theory to obtain an insight on the stability and the nature of frontier orbitals. Finally, electrostatic potential plots mapped on optimized geometries substantiate the noncovalent interactions found in their respective crystal structures. (C) 2018 Elsevier Ltd.

A new aroylhydrazone ligand, 2-benzoylpyridine-4-methoxybenzhydrazone (BPMBH). and its two cobalt(III) complexes, [Co(BPMB)(2)]NO3 center dot 1.5H(2)O (1) and [Co(BPMB)(2)]Cl center dot 2H(2)O (2) have been synthesized and structurally characterized. The synthesized compounds are physico-chemically characterized by CHN analysis, molar conductivity, magnetic susceptibility measurements and spectroscopic techniques like MS, IR, UV and NMR. The high molar conductivity values of the complexes confirmed the presence of counter ions in the lattice of the cationic complexes. The molecular structure of the aroylhydrazone and its complexes have been resolved using single crystal XRD studies. In the solid state, the aroylhydrazone exists in the amido form as evident from the IR and XRD studies. The tridentate nature of the NNO donor aroylhydrazone was also confirmed from the IR spectral studies. XRD studies reveal that in all complexes, the tridentate aroylhydrazone coordinates to the Co(III) center via pyridine nitrogen, azomethine nitrogen and iminolate oxygen and found to possess distorted octahedral geometry. The complexes are bis-ligated cationic complexes in which chloride and nitrate ions act as counter ions. The antibacterial and antifungal activities of the aroylhydrazone and its Co(III) complexes have been screened against bacterial species Staphylococcus aureus, Enterobacter aerogenes, Bacillus subtilis, Streptococcus pyogenes, Klebsiella pneumonia, Salmonella typhi and Escherichia coli. The antifungal activity was also checked using fungi Aspergillus niger, Penicillium chrysogenum and Rhizopus oryzae. From the activity data we can infer that the metal complexes have better biological activity than the metal free ligand against the bacterial and fungal species which were tested.
