Design, synthesis and evaluation of enzyme-responsive fluorogenic probes based on pyridine-flanked diketopyrrolopyrrole dyes

The ever-growing demand for fluorogenic dyes usable in the rapid construction of analyte-responsive fluorescent probes, has recently contributed to a revival of interest in the chemistry of diketopyrrolopyrrole (DPP) pigments. In this context, we have explored the potential of symmetrical and unsymmetrical DPP derivatives bearing two or one 4-pyridyl substituents acting as optically tunable group(s). The unique fluorogenic behavior of these molecules, closely linked to N-substitution/charge state of their pyridine unit (i.e., neutral pyridine or cationic pyridinium), has been used to design DPP-based fluorescent probes for detection of hypoxia-related redox enzymes and penicillin G acylase (PGA). In this paper, we describe synthesis, spectral characterization and bioanalytical validations of these probes. Dramatic differences in terms of aqueous stability and enzymatic fluorescence activation were observed. This systematic study enables to delineate the scope of application of pyridine-flanked DPP fluorophores in the field of enzyme biosensing. (C) 2020 Elsevier B.V. All rights reserved.

4-Mercaptopyridine Modified Fiber Optic Plasmonic Sensor for Sub-nM Mercury (II) Detection

In this paper, we propose and demonstrate a high-performance mercury ion sensor with sub-nM detection limit, high selectivity, and strong practicability based on the small molecule of the 4-mercaptopyridine (4-MPY) modified tilted fiber Bragg grating surface plasmon resonance (TFBG-SPR) sensing platform. The TFBG-SPR sensor has a rich mode field distribution and a narrow bandwidth, which can detect the microscopic physical and chemical reactions on the sensor surface with high sensitivity without being disturbed by the external temperature. For the environmental compatibility and highly efficient capture of the toxic mercury ion, 4-MPY is modified on the sensor surface forming a stable (4-MPY)-Hg-(4-MPY) structure due to the specific combination between the nitrogen of the pyridine moiety and the Hg2+ via multidentate N-bonding. Moreover, gold nanoparticles (AuNPs) are connected to the sensor surface through the (4-MPY)-Hg-(4-MPY) structure, which could play an important role for signal amplification. Under the optimized conditions, the limit of detection of the sensor for mercury ions detection in the solution is as low as 1.643×10(-10) M (0.1643nM), and the detection range is 1×10(-9) M – 1×10(-5) M. At the same time, the mercury ion spiked detection with tap water shows that the sensor has the good selectivity and reliability in actual water samples. We develop a valuable sensing technology for on-time environmental Hg2+ detection and in-vivo point of care testing in clinic applications.

Coordination Bonds and Diels-Alder Bonds Dual Crosslinked Polymer Networks of Self-healing Polyurethane

A dual crosslinked self-healing polyurethane was prepared with robust mechanical properties through the dynamic reversible pyridine-Fe3+ coordination bonds and Diels-Alder (DA) covalent bonds dual crosslinking strategy. Moreover, the mechanical properties and self-healing ability of polyurethane can be tuned readily by different ratio of the coordination bonds and DA bonds. Under external load, the coordination bonds serve as sacrificial bonds are broken to dissipate energy, the DA bonds can keep the shape of sample. With the coordination bonds participation, the damaged samples can be healed under moderate heating treatment or with the aid of FeCl3 solution. (c) 2019 Wiley Periodicals, Inc. J. Polym.

NMR Quantification of the Effects of Ligands and Counterions on Lewis Acid Catalysis

The relative Lewis acidity of a variety of metal-ligand catalyst complexes is quantified using P-31 NMR spectroscopy. Three P-31 NMR probes, including two new bidentate binding probes, are compared on the basis of different binding modes (i.e., monodentate vs bidentate) and the relative scale of their downfield shift upon binding to Lewis acid complexes. Bidentate coordination of catalyst complexes including metal catalysts, ligands, and counterions were assessed due to their importance to asymmetric catalysis. The effect of ligands, counterions, and additives on Lewis acidity is quantified and correlated to reaction yield at an early time point as an approximation for catalytic activity/efficiency and chelation mode in two organic transformations. Binding studies were performed under catalytically relevant conditions, giving further applicability to synthesis. Insight into activation modes are revealed through this analysis.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5315-25-3, in my other articles.

FAD/NADH Dependent Oxidoreductases: From Different Amino Acid Sequences to Similar Protein Shapes for Playing an Ancient Function

Flavoprotein oxidoreductases are members of a large protein family of specialized dehydrogenases, which include type II NADH dehydrogenase, pyridine nucleotide-disulphide oxidoreductases, ferredoxin-NAD+ reductases, NADH oxidases, and NADH peroxidases, playing a crucial role in the metabolism of several prokaryotes and eukaryotes. Although several studies have been performed on single members or protein subgroups of flavoprotein oxidoreductases, a comprehensive analysis on structure-function relationships among the different members and subgroups of this great dehydrogenase family is still missing. Here, we present a structural comparative analysis showing that the investigated flavoprotein oxidoreductases have a highly similar overall structure, although the investigated dehydrogenases are quite different in functional annotations and global amino acid composition. The different functional annotation is ascribed to their participation in species-specific metabolic pathways based on the same biochemical reaction, i.e., the oxidation of specific cofactors, like NADH and FADH(2). Notably, the performed comparative analysis sheds light on conserved sequence features that reflect very similar oxidation mechanisms, conserved among flavoprotein oxidoreductases belonging to phylogenetically distant species, as the bacterial type II NADH dehydrogenases and the mammalian apoptosis-inducing factor protein, until now retained as unique protein entities in Bacteria/Fungi or Animals, respectively. Furthermore, the presented computational analyses will allow consideration of FAD/NADH oxidoreductases as a possible target of new small molecules to be used as modulators of mitochondrial respiration for patients affected by rare diseases or cancer showing mitochondrial dysfunction, or antibiotics for treating bacterial/fungal/protista infections.

Crystallization of Organic Salts from the Gas Phase: When Does Proton Transfer Take Place?

Salt formation with proton transfer is observed in crystals grown by cosublimation of the salt coformers. Diflunisal salts were obtained with 4-[3-(pyridin-4-yl)propyl]pyridine, piperazine, and 4-dimethylaminopyridine. Modeling studies indicate that proton transfer does not take place for an acid-base H-bonded adduct in the gas phase. However, modeling larger molecular clusters shows that proton transfer can take place spontaneously within a molecular cluster in the absence of a solvent.

Synthesis and Reactivity of Heptamethylcyclohexadienyl Rhodium(III) Complexes

We report the synthesis and reactivity of the half-sandwich rhodium(III) complexes with the fully methylated cyclohexadienyl ligand C6Me7, which is analogous to the classical Cp*. The starting complex [(C6Me7)RhCl2](2) (4) was obtained in high yield (92%) by the reaction of [(cyclooctene)(2)RhCl](2) with the readily available 6-methylenehexamethylcyclohexadiene-1,4 (C6Me6=CH2) followed by addition of HCI. Reactions of complex 4 with common two-electron ligands L gave the expected adducts (C6Me7)RhCl2L (L = pyridine, P(OEt)(3), PPh3) in high yields (80-90%). At the same time, the interaction of 4 with the stronger ligand (BuNC)-Bu-t led to the replacement of the C6Me7 ligand. The cationic complex [(C6Me7)Rh(dppe)Cl]PF6 and the dicationic complex [(C6Me7)Rh(C6Me6)](BF4)(2) were obtained by abstraction of chlorides from 4 with TlPF6 or AgBF4 in the presence of the corresponding ligands. The reaction of 4 with 2-phenylpyridine in the presence of CsOAc proceeded via CH activation and gave the cyclometalated product (C6Me7)Rh(C6H4-Py)Cl in 85% yield. Accordingly, the catalytic reaction of 2-phenylpyridine with 3-hexyne in the presence of 4 (5 mol %) gave the 9,10-diethyl-8a-azaphenanthrene cation in 61% yield. However, the catalytic efficientcy of 4 was lower than that of the classical catalyst [Cp*RhCl2](2), possibly because the displacement of the cyclohexadienyl ligand interrupted the catalytic cycle. The DFT calculations suggested that the electron-donating ability of cyclic pi ligands in the rhodium complexes (CnRn)RhCl2CO decreases in the order CnRn, = C5Me5 > C6Me7 > C5H4OMe approximate to C5Me4CF3 > C5Me3(COOMe)(2) approximate to C5H4Me > C5H5 > C5H4F approximate to C5H4COOMe > C(5)a(4)CF(3).
