The C-C coupling reaction of N-electron withdrawing group (EWG) protected amides with coupling partners is one of the most important methods for C-C bond formation at the a-position of amides to directly give a-substituted amides. Of the four reactions, namely, the reaction via the generation of carbanion with an electrophile, that via the generation of carbon radical with a radical donor, that via the generation of iminium ion species with a nucleophile (oxidative coupling reaction), and that using a transition metal carbenoid, the oxidative coupling reaction presents a challenge although the reaction products are very useful for the transformation of a wide range of nitrogen-containing derivatives. In this review, recent developments in the oxidative coupling reaction of N-EWG protected amides with nucleophiles are summarized with focus on the reaction using a transition metal, the transition-metal-free reaction, the enantioselective reaction using a chiral catalysts, and the organocatalyzed oxidative coupling reaction.

The properties of gelatin oven dried at three different temperatures from unicorn leatherjacket (L50, L60 and L70) and reef cod skin (R50, R60 and R70) were investigated. The gelatin yield was higher in unicorn leatherjacket skin (12.2%) than reef cod skin (9.8%). Unicorn leatherjacket skin gelatin had a higher protein content of 88.0-88.61%, lower moisture (9.51-9.91%), fat (0.18-0.29%) and ash (0.60-0.71%) compared to reef cod skin gelatin which had 87-87.73% protein, 10.29-11.03% moisture, 0.23-0.31% fat and 0.69-0.73% ash. SDS-PAGE revealed all the gelatin samples had alpha and beta chains. Gelatin samples had a good proportion of imino acid, hydrophobic and essential amino acid. Fourier transform infrared (FTIR) spectra showed the presence of amide regions in all the samples. Differential scanning calorimetry (DSC) showed a higher melting temperature in unicorn leatherjacket skin gelatin (115.54-120.80 degrees C) than reef cod skin (106.25-118.92 degrees C). Foaming capacity and stability and emulsion stability were higher in unicorn leatherjacket skin gelatin. Emulsion activity index, fat binding and water holding capacities were higher in reef cod skin gelatin. Different oven drying temperatures has not affect the yield and quality of gelatin. This study could pave the way to utilize oven drying for the extraction of gelatin from fish skin.

Herein, the reaction of (1-methyl-1 H-benzo[d]imidazol-2-yl)methanamine (L1) with Co(H2O)(6)Cl-2, in CH3CN at 120 degrees C, leading to the 2,3,5,6-tetrakis(1-methyl-1 H-benzo[d]imidazol-2-yl)pyrazine (3), isolated as a dimeric cluster {[Co-2(II)(3)Cl-4].2 CH3CN} (2), is reported. When O-2 and H2O are present, (1-methyl-1 H-benzo[d]imidazole-2-carbonyl)amide (HL1 ‘) is first formed and crystallized as [Co-III(L1)(2)(L1 ‘)]Cl-2.2 H2O (4) before fusion of HL1 ‘ with L1, giving 1-methyl-N-(1-methyl-1 H-benzo[d]imidazol-2-carbonyl)-1 H-benzo[d]imidazol-2-carboxamide (HL2 ”) forming a one-dimensional (1D) chain of [Co-3(II)(L2 ”)(2)Cl-4](n) (5). The combination of crystallography and mass spectrometry (ESI-MS) of isolated crystals and the solutions taken from the reaction as a function time reveal seven intermediate steps leading to 2, but six steps for 5, for which a different sequence takes place. Control and isotope labeling experiments confirm the two carbonyl oxygen atoms in 5 originate from both air and water. The dependence on the metals, compared with FeCl3.6 H2O leading to a stable triheteroarylmethyl radical, is quite astounding, which could be attributed to the different oxidation states of the metals and coordination modes confirmed by DFT calculations. This metal and valence dependent process is a very useful way for selectively obtaining these large molecules, which are unachievable by common organic synthesis.

N-acetylcysteine amide ameliorates mitochondrial dysfunction and reduces oxidative stress in hiPSC-derived dopaminergic neurons with POLG mutation

The inability to reliably replicate mitochondrial DNA (mtDNA) by mitochondrial DNA polymerase gamma (POLG) leads to a subset of common mitochondrial diseases associated with neuronal death and depletion of neuronal mtDNA. Defining disease mechanisms in neurons remains difficult due to the limited access to human tissue. Using human induced pluripotent stem cells (hiPSCs), we generated functional dopaminergic (DA) neurons showing positive expression of dopaminergic markers TH and DAT, mature neuronal marker MAP2 and functional synaptic markers synaptophysin and PSD-95. These DA neurons were electrophysiologically characterized, and exhibited inward Na + currents, overshooting action potentials and spontaneous postsynaptic currents (sPSCs). POLG patient-specific DA neurons (POLG-DA neurons) manifested a phenotype that replicated the molecular and biochemical changes found in patient post-mortem brain samples namely loss of complex I and depletion of mtDNA. Compared to disease-free hiPSC-derived DA neurons, POLG-DA neurons exhibited loss of mitochondrial membrane potential, loss of complex I and loss of mtDNA and TFAM expression. POLG driven mitochondrial dysfunction also led to neuronal ROS overproduction and increased cellular senescence. This deficit was selectively rescued by treatment with N-acetylcysteine amide (NACA). In conclusion, our study illustrates the promise of hiPSC technology for assessing pathogenetic mechanisms associated with POLG disease, and that NACA can be a promising potential therapy for mitochondrial diseases such as those caused by POLG mutation.

Intermolecular Pummerer Coupling with Carbon Nucleophiles in Non-Electrophilic Media

A new Pummerer-type C-C coupling protocol is introduced based on turbo-organomagnesium amides, which unlike traditional Pummerer reactions, does not require strong electrophilic activators, engages a broad range of C(sp(3))-, C(sp(2))-, and C(sp)-nucleophiles, and seamlessly integrates with C-H and C-X magnesiation. Given the central character of sulfur compounds in organic chemistry, this protocol allows access to unrelated carbonyls, olefins, organometallics, halides, and boronic esters through a single strategy.

The effect of pendant group structure on the thermoresponsive properties of N-substituted polyesters

Synthetic polymers exhibiting reversible lower critical solution temperature (LCST), such as poly(N-iso-propylacrylamide) (PNIPAM), are intriguing materials with various potential applications. We recently developed a new class of biodegradable thermoresponsive polyesters (TR-PEs) based on N-substituted diol monomers. TR-PEs exhibited reversible cloud point temperatures (Tcp) between 0-50 degrees C and were shown to be non-cytotoxic. The synthesis of N-substituted diols and TR-PEs is highly modular, allowing for a wide variety of possible homo-and copolyesters. In this work, we report the synthesis and characterization of 20 homopolyesters in order to better understand the structure-property relationship of TR-PEs. UV-vis spectroscopy showed that the Tcp of TR-PEs was highly dependent on pendant group structure, such as secondary or tertiary amides, cyclic and linear groups, and substitution of oxygen atoms. Structure-Tcp analysis provides a correlation between Tcp and the number of heteroatoms relative to the number of carbon atoms in the pendant group thereby providing a rationale for the design of thermoresponsive polyesters with desired Tcp values. To demonstrate the expanded tunability of the TR-PE system, copolyesters bearing covalently attached ibuprofen were synthesized and shown to exhibit LCST behavior dependent on comonomer hydrophilicity.

Pepsin-Soluble Collagen from the Skin of Lophius litulo: A Preliminary Study Evaluating Physicochemical, Antioxidant, and Wound Healing Properties

The structure of pepsin-solubilized collagen (PSC) obtained from the skin of Lophius litulon was analyzed using the sodium dodecylsulphate polyacrylamide gel electrophoresis (SDS-PAGE), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). SDS-PAGE results showed that PSC from Lophius litulon skin was collagen type I and had collagen-specific alpha 1, alpha 2, beta, and gamma chains. FTIR results indicated that the infrared spectrum of PSC ranged from 400 to 4000 cm(-1), with five main amide bands. SEM revealed the microstructure of PSC, which consisted of clear fibrous and porous structures. In vitro antioxidant studies demonstrated that PSC revealed the scavenging ability for 2,2-diphenyl-1-picrylhydrazyl (DPPH), HO, O-2(-), and ABTS. Moreover, animal experiments were conducted to evaluate the biocompatibility of PSC. The collagen sponge group showed a good biocompatibility in the skin wound model and may play a positive role in the progression of the healing process. The cumulative results suggest that collagen from the skin of Lophius litulon has potential applications in wound healing due to its good biocompatibility.

Green extraction of perilla volatile organic compounds by pervaporation

Volatile organic compounds (VOCs) present in perilla essential oil are of high interest in medicinal and food processing. In this work, pervaporation was implemented to extract the valuable perilla VOCs from dilute aqueous solutions as a green process. Three representative VOCs of perilla (i.e., limonene, linalool, and perillaldehyde) having different functional groups were selected as model components, and poly(ether-block-amide) (PEBA) and polydimethylsiloxane (PDMS) membranes were prepared for the VOC extraction studies. The influences of operating conditions (i.e., feed concentration and temperature) on the pervaporation performance of the membranes were investigated. In binary VOC/water mixtures, an increase in the feed concentration increased the VOC flux and decreased the separation factor. The VOC flux also increased significantly with temperature, mainly due to an augmented driving force for permeation. The impact of the coupling effects in multicomponent permeation was evaluated by comparing the pervaporation performance of VOCs in binary VOC/water and quaternary VOCs/water systems. Results show that the VOC permeation behavior was affected by the presence of other VOCs, depending on the permeant-permeant and membrane-permeant interactions. Based on pervaporation separation index, the PEBA membrane showed a better overall separation efficiency than the PDMS membrane for the extraction of perilla VOCs. Since pervaporation does not involve any chemical solvents and operates at moderate temperatures, it provides a green process for extracting valuable perilla VOCs.
