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).

Aryl and heteroaryl chiral carbinols are useful precursors in the synthesis of drugs. Lactobacillus paracasei BD87E6, which is obtained from a cereal based fermented beverage, was investigated as whole cell biocatalyst for the bioreduction of different ketones (including aromatic, hetero-aromatic and fused bicyclic ketone) into chiral carbinols, which can be used as a pharmaceutical intermediate. The study shows that bioreduction of aryl, heteroaryl and fused bicyclic ketone (1-5) to their corresponding chiral carbinols (1a-5a) in excellent enantioselectivity (>99%) with high yields. This study gave the first example for an enantiopure production of (S)-6-chlorochroman-4-ol (3a), which has many antioxidant activity, by a biological method. For asymmetric bioreduction of other prochiral ketones, these results open way to use of L. paracasei BD87E6 as biocatalysts. Also, the present process shows a hopeful and alternative green synthesis for the production of enantiopure carbinols in a mild, inexpensive and environmentally friendly process.

A new unsymmetrical N2O2-tetradentate Schiff-base complex of zinc(II) was synthesized by the template reaction of pyridoxal-S-methylthiosemicarbazone and 2-hydroxy-4-methoxy-benzaldehyde as starting compounds. S-methylthiosemicarbazone (1) and zinc(II) complex [Zn(L)CH3OH] ( 2) were characterized by elemental analysis, FT-IR, UV-visible, H-1, and C-13 NMR spectra. The molecular structure of the complex (2) was determined by single crystal X-ray diffraction technique. The structure consists of a distorted square-pyramidal geometry around the central metal, Zn(II). Quantum chemical calculations were carried out using density functional theory DFT/B3LYP, 6-31G (d), and LanL2DZ basis sets for theoretical characterization of the compounds. The experimental and theoretical data were compared comprehensively. The potential energy distribution (PED) analysis was performed for the assignment of vibration frequencies. In order to support in vitro studies, molecular docking studies have been carried out so that the title compound can be an inhibitor of Epidermal Growth Factor Receptor (1 m17), and the relationship between calculated HOMO energies and docking studies has been examined. In addition, the total antioxidant capacity (as TEAC value) and free radical scavenging activity of the compounds were determined by Cupric Reducing Antioxidant Capacity (CUPRAC) and 1,1-diphenyl-2-picryl hydrazyl (DPPH) methods, respectively.

We herein report the fabrication of a bifunctional iron nanocomposite catalyst, in which two catalytically active sites of Fe-N-x and Fe phosphate, as oxidation and Lewis acid sites, were simultaneously integrated into a hierarchical N,P-dual doped porous carbon. As a bifunctional catalyst, it exhibited high efficiency for direct oxidative cleavage of alkenes into ketones or their oxidation into 1,2-diketones with a broad substrate scope and high functional group tolerance using TBHP as the oxidant in water under mild reaction conditions. Furthermore, it could be easily recovered for successive recycling without appreciable loss of activity. Mechanistic studies disclose that the direct oxidation of alkenes proceeds via the formation of an epoxide as intermediate followed by either acid-catalyzed Meinwald rearrangement to give ketones with one carbon shorter or nucleophilic ring-opening to generate 1,2-diketones in a cascade manner. This study not only opens up a fancy pathway in the rational design of Fe-N-C catalysts but also offers a simple and efficient method for accessing industrially important ketones and 1,2-diketones from alkenes in a cost-effective and environmentally benign fashion.

A series of halogenated imidazo[1,5-alpha]pyridines was prepared and their structural and optical properties investigated. The products were characterized by spectroscopic techniques and their optical properties discussed in relation to their chemical structure. We were able to triplicate the luminescence quantum yields (phi) in solution for three different imidazo[1,5-alpha]pyridine derivatives, depending on the halogen nature of the substituent on the imidazo[1,5-alpha]pyridine moiety. The effect of the halogen and of the geometrical and chemical characteristics of the molecular skeleton on the crystal packing was studied in the solid state by single crystal X-ray diffraction. At the same time, the possible presence of halogen bonds was evaluated through solid-state NMR analysis.
