Photoredox-mediated remote C(sp3)-H heteroarylation of free alcohols

We report an efficient and economical method for remote delta C(sp3)-H heteroarylation of free aliphatic alcohols using a hypervalent iodine PFBI-OH oxidant under photoredox catalysis. The reaction sequence involves in situ alcoholysis of PFBI-OH with alcohol, generation of an alkoxy radical intermediate by SET reduction, 1,5-HAT, and Minisci-type C-C bond formation. This method uses a slight excess of alcohols, can facilitate reaction at delta methyl and methylene positions, and has been successfully applied to modification of complex drug molecules.

Bridging ligands comprising two or more di-2-pyridylmethyl or amine arms: Alternatives to 2,2′-bipyridyl-containing bridging ligands

Bridging ligands incorporating 2,2′-bipyridine as a chelating component have been utilised for several decades and are widely employed in coordination chemistry, supramolecular chemistry and materials synthesis. Such ligands form stable 5-membered chelate rings upon coordination to a metal. Two related chelating units, di-2-pyridylamine and di-2-pyridylmethane, which form 6-membered chelate rings when coordinated to a metal, have been studied far less as components of bridging ligands but have recently garnered significant levels of attention. Of around 140 reports on the incorporation of these moieties into bridging ligands some 75% have been published in the last 15 years. This review covers the synthesis of bridging ligands containing di-2-pyridylamine and di-2-pyridylmethane chelating moieties, and a survey of their coordination and supramolecular chemistry. Applications of the resulting systems as structural and functional models of enzyme active sites, and spin-crossover materials, and for investigations into anion-pi interactions are covered.

Review of the methods for determination of reactive oxygen species and suggestion for their application in advanced oxidation induced by dielectric barrier discharges

Advanced oxidation processes (AOPs) particularly non-thermal plasmas based on electrical discharges have been widely investigated for water and wastewater treatment. Dielectric barrier discharges (DBDs) generate large amounts of selective and non-selective reactive oxygen species (ROS) such as ozone, hydrogen peroxide, atomic oxygen, superoxide molecular anions and hydroxyl radicals, having been proved to be efficient for water decontamination among various forms of electrical discharge systems. The detection and quantification methods of these oxygen species in non-thermal plasmas have been reviewed. However, their application in dielectric barrier discharge has not been well studied. It is therefore imperative to summarise the various detection and quantification methods for oxygen-based species determination in AOPs, aqueous systems and non-thermal plasma processes. Thereafter, reviewed methods are suggested for the determination of ROS in DBD configurations to understand the consumption trend of these oxidants during treatment of water effluents and to evaluate the performance of the treatment reactor configuration towards the degradation of targeted pollutants.

Optimization of the expression of human aldehyde oxidase for investigations of single-nucleotide polymorphisms

Aldehyde oxidase (AOX1) is an enzyme with broad substrate specificity, catalyzing the oxidation of a wide range of endogenous and exogenous aldehydes as well as N-heterocyclic aromatic compounds. In humans, the enzyme’s role in phase I drug metabolism has been established and its importance is now emerging. However, the true physiologic function of AOX1 in mammals is still unknown. Further, numerous single-nucleotide polymorphisms (SNPs) have been identified in human AOX1. SNPs are a major source of interindividual variability in the human population, and SNP-based amino acid exchanges in AOX1 reportedly modulate the catalytic function of the enzyme in either a positive or negative fashion. For the reliable analysis of the effect of amino acid exchanges in human proteins, the existence of reproducible expression systems for the production of active protein in ample amounts for kinetic, spectroscopic, and crystallographic studies is required. In our study we report an optimized expression system for hAOX1 in Escherichia coli using a codon-optimized construct. The codon-optimization resulted in an up to 15-fold increase of protein production and a simplified purification procedure. The optimized expression system was used to study three SNPs that result in amino acid changes C44W, G1269R, and S1271L. In addition, the crystal structure of the S1271L SNP was solved. We demonstrate that the recombinant enzyme can be used for future studies to exploit the role of AOX in drug metabolism, and for the identification and synthesis of new drugs targeting AOX when combined with crystallographic and modeling studies.

Strategies to target the Hedgehog signaling pathway for cancer therapy

Hedgehog (Hh) signaling is an essential pathway in the human body, and plays a major role in embryo development and tissue patterning. Constitutive activation of the Hh signaling pathway through sporadic mutations or other mechanisms is explicitly associated with cancer development and progression in various solid malignancies. Therefore, targeted inhibition of the Hh signaling pathway has emerged as an attractive and validated therapeutic strategy for the treatment of a wide range of cancers. Vismodegib, a first-in-class Hh signaling pathway inhibitor was approved by the US Food and Drug Administration in 2012, and sonidegib, another potent Hh pathway inhibitor, received FDA’s approval in 2015 as a new treatment of locally advanced or metastatic basal cell carcinoma. The clinical success of vismodegib and sonidegib provided strong support for the development of Hh signaling pathway inhibitors via targeting the smoothened (Smo) receptor. Moreover, Hh signaling pathway inhibitors aimed to target proteins, which are downstream or upstream of Smo, have also been pursued based on the identification of additional therapeutic benefits. Recently, much progress has been made in Hh singling and inhibitors of this pathway. Herein, medicinal chemistry strategies, especially the structural optimization process of different classes of Hh inhibitors, are comprehensively summarized. Further therapeutic potentials and challenges are also discussed.

Reactions of thermally generated benzynes with six-membered: N -heteroaromatics: Pathway and product diversity

We report here various pathways by which six-membered N-heteroaromatic compounds react with benzynes that are generated by the HDDA reaction. The initially formed 1,3-zwitterionic species (a) can collapse intramolecularly to give novel 1 : 1 adducts of the heterocycle and benzyne; (b) can react with an externally added, electrophilic third-component to give functionalized heterocyclic products; or (c) can react with an external protic nucleophile to produce, following collapse of the ion pair resulting from protonation of the zwitterion, a variety of three-component assemblies. Mechanisms for formation of some of the 1 : 1 adducts are supported by DFT methods. The scope of the protic nucleophilic coupling was also expanded to a two-pot operation by using triflic acid as a protic “non-nucleophile”, followed by the addition of a suitably reactive nucleophile.

Metal-organic networks of CuCN with diimines (L) = pyrazine (Pyz), 2-aminopyrazine (PyzNH2), quinoxaline (Qox), phenazine (Phz), 4,4?-bipyridyl (Bpy), pyrimidine (Pym), 2-aminopyrimidine (PymNH 2), 2,4-diaminopyrimidine (Pym(NH2)2), 2,4,6-triaminopyrimidine (Pym(NH2)3), quinazoline (Qnz), pyridazine (Pdz), and phthalazine (Ptz) were studied. Open reflux reactions produced complexes (CuCN)2(L) for L = Qox, Phz, Bpy, PymNH 2, Pym(NH2)2, Qnz, and Pdz and (CuCN) 3(L) complexes for L = Pyz, PyzNH2, Qox, Bpy, Pym(NH 2)3,l and Pdz. Also produced were (CuCN) 3(Pyz)2, (CuCN)(PyZNH2), (CuCN) 7(Pym)2, (CuCN)5(Qnz) 2 and (CuCN)5(Ptz)2. X-ray structures are presented for (CuCN)2(Pdz), (CuCN)2(PymNH2), and (CuCN) 7(Pym)2. Hydrothermal reactions yielded additional X-ray structures of (CuCN)2(PyzNH2), (CuCN) 3(Pym(NH2)2), (CuCN)4(Qnz), a second (CuCN)2(Pdz) phase, (CuCN)5(Pdz)2, (CuCN) 2(Ptz), and (CuCN)7(Ptz)2. Structural trends, including cuprophilic interactions and cyano-bridged Cu2(CN) 2 dimer formation, are discussed. Particularly short Cu…Cu interactions are noted for the novel 4- and 5-coordinate Cu2-(CN) 2 dimers. Thermal analyses show that most of the complexes decompose with loss of L around 160-180C. Luminescence behavior is relatively weak in the products.
