New copper(II) hydrazone complexes with (Z)-2-(phenyl(2-(pyridin-2-yl)hydrazono)methyl)pyridine (L) were synthesized and characterized using various physicochemical methods. The geometries of the complexes can be classified as mononuclear and binuclear. The complex 1, [Cu(L)(Cl)(2)], is mononuclear whereas the solid-state structure of complex 2 contain a mixture of co-crystals of the mono- and binuclear complexes 2a, [Cu(L)(H2O)(SO4)], and 2b, [Cu-2(L)(2)(mu-SO4)(2)]. The unit cell of 2 contains two units of the mononuclear complex 2a and one units of the binuclear complex 2b. The copper atoms contained in all the mono- and binuclear complexes are in a distorted square pyramidal geometry. The present study indicates that complexes having different nuclearities and geometries can be achieved by changing the synthetic conditions and methods. Variable temperature magnetic susceptibility measurements of the complexes have shown the presence of weak anti-ferromagnetic interactions. These interactions are mediated by intermolecular hydrogen bonding in 1 and through a symmetric sulfate bridge in 2. The EPR spectra in the polycrystalline state for 1 and 2 exhibited a broad signal at similar to 2.149 due to spin-spin interactions between two copper(II) ions. The cyclic voltammograms of complexes 1 and 2 in DMSO gave two irreversible redox waves. Density functional theory (DFT) calculations were evaluated in the study, involving the molecular specification with the use of B3LYP/LANL2DZ formalism for the copper atoms and B3LYP/6-31G for the remaining atoms. Both complexes catalyzed the dismutation of superoxide (O-2(center dot-)). Furthermore, the copper complexes and the ligand were tested to explore their anticancer properties. Promising cytotoxicity of the synthesized compounds was observed against the selected cancerous cell lines of neuroblastoma, lung carcinoma, hepatocellular carcinoma and breast cancer.

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.

Pyridotriazoles are utilized as robust building blocks to access alpha-secondary and alpha-tertiary pyridines via the development of a simple yet practically useful metal-free denitrogenative C-C cross-coupling with boronic acids. The reaction shows a high level of functional tolerance, broad substrate scope, and facile scalability. The synthetic potential of the method is demonstrated by the strurctural modification of a bioactive molecule and concise synthesis of pheniramine analogs.

Magnetic Fe3O4 nanoparticles as a support were modified with an amino-terminated organosilicon and cyanoric choloride ligands. The novel manganese complex was grafted on modified magnetic support (Mn(II)-Met@MMNPs). The nanocatalyst structure, particle size, morphology and surface properties was well characterized by elemental analysis, ICP-AES, MS, EDS, FT-IR, SEM, TEM, DLS, VSM, TGA, XRD and XPS. In order to develop an effective heterogeneous nanocatalyst for eco-friendly aerobic, highly active and selective catalytic reactions, synthesized nanocatalyst was applied in oxidation of various organic compounds. The catalytic performance of the manganese nanocatalyst in the aerobic oxidation of ethylbenzene (EB), cyclohexene (CYHE) and various aldoximes and ketoxime were studied. Selective aerobic oxidation of EB and CYHE and various oximes were catalyzed by the Mn-nanocatalyst using N-hydroxyphthalimide (NHPI) with molecular oxygen as the green oxidant without the need of any reducing agent, and respectively the acetophenone (AcPO) as a benzylic product, 2-cyclohexene-1-one (CYHE=O) as an allylic product and corresponding carbonyl compounds were obtained. The oxidation process has been optimized for Mn-nanocatalyst by considering the effect of different parameters such as the ratio and amount of Mn-nanocatalystiNHPI, reaction time and solvent for achieving maximum conversion and selectivity to products. Due to their significant low cost, informal preparation, easy magnetically separation from reaction mixture, excellent catalytic performance, simple recovery and reusability without any metal leaching, the Mn-nanocatalyst has huge application prospect in selective and green oxidation process.

I found the field of Biotechnology & Applied Microbiology; Food Science & Technology very interesting. Saw the article Effect of temperature on saccharification and oligosaccharide production efficiency in koji amazake published in 2019.0.

Koji amazake, prepared from rice koji, is a traditional Japanese sweet beverage. The main source of sweetness is glucose derived from rice starch following digestion by enzymes of Aspergillus oryzae during saccharification. The temperature of this process was empirically determined as 45 degrees C-60 degrees C, but no studies have systematically investigated the effect of temperature on saccharification efficiency. We addressed this in the present study by evaluating saccharification efficiency at various temperatures. We found that glucose content was the highest at 50 degrees C (100%) and was reduced at temperatures of 40 degrees C (66.4%), 60 degrees C (91.9%), and 70 degrees C (76.6%). We previously reported that 12 types of oligosaccharides are present in koji amazake; the levels of eight of these, namely nigerose, kojibiose, trehalose, isomaltose, gentiobiose, raffinose, panose, and isomaltotriose, were the highest at 50 degrees C-60 degrees C, whereas sophorose production was maximal at 70 degrees C. Based on these findings, we initially performed saccharification at 50 degrees C and then switched the temperature to 70 degrees C. The maximum amount of each saccharide including sophorose that was produced was close to the values obtained at these two temperatures. Thus, oligosaccharide composition of koji amazake is dependent on saccharification temperature. These findings provide useful information for improving the consumer appeal of koji amazake by enhancing oligosaccharide content. (C) 2018, The Society for Biotechnology, Japan. All rights reserved.

A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

Aberrant activation of ERK signaling pathway usually leads to oncogenesis, and small molecular agents targeting this pathway are impeded by the emergence of drug resistance due to reactivation of ERK signaling. Compound DEL-22379 has been reported to inhibit ERK dimerization which was unaffected by drug-resistant mechanism reactivating the ERK signaling. Here, we discussed a structure-activity relationship study of DEL-22379. Forty-seven analogues were designed and synthesized. Each synthesized compound was biologically evaluated for their inhibitory rates on several tumor cell lines and compounds with high inhibitory rates were further evaluated for IC50 values. The structure-activity relationship of idolin-2-one scaffold and the impact of Z/E configuration on potency were discussed. Potential safety of two synthesized analogues was investigated and in silico docking study of five compounds was performed to understand the structural basis of ERK dimerization inhibition.

The carbonylative Suzuki cross-coupling of 2-bromopyridine with various boronic acids to prepare unsymmetrical arylpyridine ketones has been carried out using palladium/N-heterocyclic carbene complexes as catalysts prepared in situ. The selectivity and the rate of these reactions are highly dependent on the conditions, i.e., nature of the palladium catalyst precursor, solvent, temperature and CO pressure. The main side-products arise from direct, non-carbonylative cross-coupling. Under the optimum conditions, arylpyridine ketones are recovered in high yields (60-88%). The antibacterial activities of the corresponding benzimidazole salts 2 were tested against Gram positive and negative bacteria using the agar dilution procedure, and their IC50 values have been determined.

The synthesis of a novel class of cyclometalated gold(III) complexes supported by benzoylpyridine, benzylpyridine, and (1R,2R)-(+)-1,2-diaminocyclohexane (DACH) ligands, along with their crystal structures, is reported. These compounds provide a new scaffold to investigate biological properties of gold(III) complexes. The six complexes were prepared and characterized, following reactions of (C,N) cyclometalated gold(III) scaffolds, [Au(C boolean AND N)Cl-2] with DACH, which yielded a new series of cyclometaled gold(III), 3-5, of the type [Au(C boolean AND NH)(DACH)(2)](+) and the nitrogen substituted cyclometalated Au(III), 6-8, of the type [Au-(C boolean AND N)(DACH)](2+). Antiproliferative activity of these complexes in a panel of cancer cells showed promising results with IC50 in the micromolar range and selectivity over normal epithelial cells, MRCS. Whereas 8 shows minimal interaction with superhelical DNA except at high gold concentrations of 500 mu M, complex 5 does not show interaction even at 1000 mu M. The complexes display significant uptake in OVCAR8 cancer cells within 200-1200 pmol/million cells with the exception of complex 4. Differential cellular uptake was observed for the complexes; for example, while 3 and 8 display significant uptake, 4 showed minimal uptake. The compounds proved to be stable under physiological conditions and were minimally affected by either glutathione or sodium ascorbate. Cell cycle studies reveal a G1 arrest induced by representative complexes. The results reveal that enhanced Au(III) stabilization promoted by combined cyclometalated and DACH ligands may offer ligand tuning insights for novel anticancer drug design.
