A metal-free access to 2-iodo-1,3-disubstituted indolizines has been developed. The proposed synthesis is relatively simple and efficient and involves the iodine-triggered 5-endo-trig cyclization of 2-pyridylallene precursors. While it can be conducted on a gram scale, the preparation of the precursors is straightforward and does not always require intermediate purifications. The obtained 2-iodoindolizines can be further functionalized through cross-coupling reactions.

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.

This work disclosed a highly enantioselective hydrogenation of non-ortho-substituted 2-pyridyl aryl ketones via Ir/f-diaphos catalysis. This catalytic system allows for full control over the configuration of the stereocenter, affording two enantiomers of the desired products with extremely high enantioselectivity (up to >99% ee in most cases) and excellent reactivity (TON of up to 19600, TOF of 1633 h(-1)) under mild conditions. Density functional theory calculations and control experiments revealed that the relay hydrogen bonding among the solvent isopropanol, substrate, and ligand is crucial for high ee’s.

Small-scale culture of animal cells in suspension is of importance for many applications. At a small-scale, fed-batch is achieved either by manual bolus feeding or the use of liquid handling robots. In this study, we report an alternate application of a hydrogel for in situ continuous delivery of a nutrient feed comprising 18 amino acids, vitamins, antioxidants, and trace elements. We show that amino acid release is sustained for at least seven days. Importantly, release rates of individual amino acids can be independently modulated by changing their loading. We demonstrate the application of this hydrogel for complete in situ feeding of nutrients to a suspension adapted CHO cell line expressing IgG leading to 2.7-fold and 4-fold improvement in integral viable cell density (IVCD) and volumetric productivity respectively. This is similar to improvements obtained by bolus liquid feeding. Further, supplying glucose from the same hydrogel to eliminate manual feeding led to a 1.8-fold increase in IVCD accompanied by a 3-fold increase in volumetric productivity as compared to batch culture. In summary, this study provides a proof-of-concept that hydrogels can enable completely closed in situ feeding for mammalian cell culture requiring no external intervention. Such continuous in situ delivery can potentially enable closed culture systems maintaining nutrients at low levels mimicking physiological concentrations.

For the first time, square planar Pd(II) complexes of hydrazone ligands have been investigated as the emissive components of light-emitting electrochemical cells (LECs). The neutral transition metal complex, [Pd(L-1)(2)]center dot 2CH(3)OH (1), (HL1 = (E)-N’-(phenyl(pyridin-2-yl) methylene)isonicotinhydrazide), was prepared and structurally characterized. Complex 1 displays quasireversible redox properties and is emissive at room temperature in solution with a lambda(max) of 590 nm. As a result, it was subsequently employed as the emissive material of a single-layer LEC with configuration FTO/1/Ga/In, where studies reveal that it has a yellow color with CIE(x, y) = (0.33, 0.55), a luminance of 134 cd cm(-2), and a turn-on voltage of 3.5 V. Protonation of the pendant pyridine nitrogen atoms of L-1 afforded a second ionic complex [Pd((LH)-H-1)(2)](ClO4)(2) (2) which is also emissive at room temperature with a lambda(max) of 611 nm, resulting in an orange LEC with CIE(x, y) = (0.43, 0.53). The presence of mobile anions and cations in the second inorganic transition metal complex resulted in more efficient charge injection and transport which significantly improved the luminance and turn-on voltage of the device to 188.6 cd cm(-2) and 3 V, respectively. This study establishes Pd(II) hydrazone complexes as a new class of materials whose emissive properties can be chemically tuned and provides proof-of-concept for their use in LECs, opening up exciting new avenues for potential applications in the field of solid state lighting.

Hydrogen polysulfides (H2Sn, n > 1) belong to sulfane sulfur in the reactive sulfur species (RSS) family and play significant roles in maintaining biological homeostasis in organisms. The detection of H2Sn in living systems is essential, but further understanding of its intact function in living cells has been limited, owing to the lack of appropriate analytical tools. In this work, a new fluorescent probe PP-PS was designed for the detection of endogenous H2Sn. The probe has a large Stokes shift (178 nm), low detection limit (1 nM), and short response time (1 minute). Besides, PP-PS was successfully applied in the imaging of endogenous H2Sn in lysosomes of living cancer cells, xenograft mouse tumor tissues, and LPS-induced mouse inflammation tissues. These results revealed that the probe PP-PS could act as a new fluorescence imaging tool to study the function of intracellular hydropolysulfides.

In this study, we synthesize 2-amino-4-alkyl/aryl-6-(hydroxymethyl)-8-oxopyrano[3,2-b] pyran-3-carbonitriles derivatives using a multicomponent reaction featuring aromatic or aliphatic aldehydes, kojic acid, and malononitrile catalyzed by nano fluoroapatite doped with Si and Mg (Si-Mg-FA). All reactions were carried out in EtOH as the solvent under reflux and green condition. The process demonstrates various advantages, including high yields, short reaction times, and simple workup. In addition, toxic organic solvent is not used, nor is chromatographic purification of products required. We characterized the synthesized compounds by Fourier transform infrared,(CNMR)-C-13, and(1)HNMR spectroscopies. Additionally, the antibacterial properties of the pyrano[3,2-b]pyran derivatives were evaluated by determining the minimum inhibitory concentration on two gram-positive and gram-negative bacteria using the macro dilution method and compared with Penicillin and Tetracycline at the same conditions. The 2-amino-4-(2,4-dichlorophenyl)-4,8-dihydro-6-(hydroxymethyl)-8-oxo-pyrano[3,2-b]pyran-3-carbonitrile and the 2-amino-4-hexyl-4,8-dihydro-6-(hydroxymethyl)-8-oxo-pyrano[3,2-b]pyran-3-carbonitrile show the best antibacterial activity with a MIC value of 62.5 mu g/ml againstStaphylococcus aureus(ATCC 25923). Moreover, the antioxidant properties of the pyrano[3,2-b] pyrans derivatives were evaluated. It is notable that pyrano[3,2-b] pyrans derivatives, synthesized with substituent groups on benzaldehyde such as-NO2, -COOCH3, -OMe show the best antioxidant activity measured by DPPH radical-scavenging method.

N-(Pyrid-2-yl)-substituted azolium and pyridinium salts, precursors for hybrid NHC-containing ligands, were obtained with excellent regioselectivity, employing a deoxygenative CH-functionalization of pyridine-N-oxides with substituted imidazoles, thiazoles, and pyridine. Unlike the traditional SNAr-based methods, this approach provides high yields for substrates bearing substituents of different electronic nature. The utility of azolium and pyridinium salts thus prepared was also highlighted by the synthesis of pyridyl-substituted imidazolyl-2-thione, benzodiazepine as well as 2-aminopyridines.
