AbstractIn this research, initial production and characterization of a novel Brønsted-acidic ionic liquid, namely,N,N,N′,N′-tetramethylethylenediaminium-N,N′-disulfonic acid hydrogen sulfate ([TMEDSA][HSO4]2), has been described (characterization was achieved using Fourier-transform infrared spectroscopy,1H nuclear magnetic resonance (NMR),13C NMR, and mass and thermal gravimetric spectra). Thereafter, utilization of [TMEDSA][HSO4]2as a highly effectual catalyst for the synthesis of 4,4′-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives through the one-pot pseudo five-component reaction of phenylhydrazine (2 eq.) with ethyl acetoacetate (2 eq.) and arylaldehydes (1 eq.) in relatively mild conditions, has been reported.

Redox cofactors are utilized by a myriad of proteins, ranging from metabolic enzymes to those performing post-translational modifications. Labeled redox cofactors have served as a vital tool for a broad range of studies. This account describes chemoenzymatic syntheses of the isotopically labeled, biologically important redox cofactors: nicotinamide adenine dinucleotide, methylene tetrahydrofolate, and flavin nucleotides. An overview of the general strategy is presented. These examples demonstrate the utility of enzymatic synthesis.1 Introduction2 Nicotinamide Cofactors2.1 Synthesis of Remote-Labeled 14C-NADPH2.1.1 Synthesis of [Ad-14C]NADPH2.1.2 Synthesis of [Carbonyl-14C]NADPH2.2 Synthesis of S- and R-[4-3H]NADPH2.2.1 One-Step S- and Three-Step R-[4-3H]NADPH Synthesis2.2.2 One-Pot, One-Step R-[4-3H]NADPH Synthesis2.3 Synthesis of S- and R-[Ad-14C, 4-2H]NADPH2.3.1 One-Step S-, Three-Step R-[Ad-14C, 4-2H]NADPH Synthesis2.3.2 One-Pot, One-Step R-[Ad-14C, 4-2H]NADPH Synthesis3 Methylene Tetrahydrofolate4 Flavin Nucleotides5 Conclusions and Outlook

Using N,N-dimethylacetamide (DMAc) as a reducing agent in the presence of PVP-K30, the stable silver nanoparticles (Ag-NPs) solution was prepared by a convenient method for the in situ reduction of silver nitrate. The cellulose–Ag-NPs composite film (CANF) was cast in the same container using lithium chloride (LiCl) giving the Ag-NPs-PVP/DMAc solution cellulose solubility as well as γ-mercaptopropyltrimethoxysilane (MPTS) to couple Ag-NPs and cellulose. The results showed that the Ag-NPs were uniformly dispersed in solution, and the solution had strong antibacterial activities. It was found that the one-pot synthesis allowed the growth of and cross-linking with cellulose processes of Ag-NPs conducted simultaneously. Approximately 61% of Ag-NPs was successfully loaded in CANF, and Ag-NPs were uniformly dispersed in the surface and internal of the composite film. The composite film exhibited good tensile properties (tensile strength could reach up to 86.4 MPa), transparency (light transmittance exceeds 70%), thermal stability, and remarkable antibacterial activities. The sterilization effect of CANF0.04 against Staphylococcus aureus and Escherichia coli exceed 99.9%. Due to low residual LiCl/DMAc and low diffusion of Ag-NPs, the composite film may have potential for applications in food packaging and bacterial barrier.
