Non-precious electrocatalysts for oxygen reduction reaction in alkaline media: Latest achievements on novel carbon materials

Low temperature fuel cells (LTFCs) are considered as clean energy conversion systems and expected to help address our society energy and environmental problems. Up-to-date, oxygen reduction reaction (ORR) is one of the main hindering factors for the commercialization of LTFCs, because of its slow kinetics and high overpotential, causing major voltage loss and short-term stability. To provide enhanced activity and minimize loss, precious metal catalysts (containing expensive and scarcely available platinum) are used in abundance as cathode materials. Moreover, research is devoted to reduce the cost associated with Pt based cathode catalysts, by identifying and developing Pt-free alternatives. However, so far none of them has provided acceptable performance and durability with respect to Pt electrocatalysts. By adopting new preparation strategies and by enhancing and exploiting synergetic and multifunctional effects, some elements such as transition metals supported on highly porous carbons have exhibited reasonable electrocatalytic activity. This review mainly focuses on the very recent progress of novel carbon based materials for ORR, including: (i) development of three-dimensional structures; (ii) synthesis of novel hybrid (metal oxide-nitrogen-carbon) electrocatalysts; (iii) use of alternative raw precursors characterized from three-dimensional structure; and (iv) the co-doping methods adoption for novel metal-nitrogen-doped-carbon electrocatalysts. Among the examined materials, reduced graphene oxide-based hybrid electrocatalysts exhibit both excellent activity and long term stability.

Effects of the auxiliary ligands on the structures of diphenate complexes: From ID helical chain to 2D network

Two coordination polymers, [Cd(dpa)(L1)] (1) and [Cd(dpa)(L2)] ·CH3CH2OH3(2) (L1 = 2,6-bis(1H- benzimidazol-2yl)pyridine, L2 = 2,2?-(l,4-butanediyl) bis (1H- benzimidazole) (L2), both of which contain helical chain subunits, were synthesized by the reaction of CdII salts and diphenic acid (H 2dpa) with rigid, chelating and flexible, bridging auxiliary ligands, respectively. Compound 1 has a 1D helical chain structure, in which dpa 2- as bridging ligand is responsible for the formation of the main framework and L1 as chelating ligand grafts on one side of the helical chain. This structure is further extended into a 3D supramolecular framework through two kinds of strong hydrogen bonding interactions. Compound. 2 has a 2D structure, in which dpa2- bridges the CdII atoms into helical chains and L2 bridges the left- and right-handed chains into a racemic layer with, a [4,4] topology.

Synthesis, spectroscopic and crystallographic studies on two copper(II) benzimidazole complexes: Supramolecular frameworks built from N-H…O, N-H…Cl and O-H…Cl hydrogen bonds

The tridentate ligands 2,6-bis(benzimidazole-2?-yl)pyridine (L 1) and N,N-bis(benzimidazole-2?-yl-methyl)amine (L2) with N3 donor set form the corresponding mononuclear [Cu(L 1)(ClO4)(Cl)].H2O] (1) and [Cu(L 2)(Cl2)].H2O (2) complexes, which have been characterized by elemental analysis, UV-Vis spectra, IR, EPR and magnetic moment studies. Single crystal X-ray structure studies for both the complexes show that coordination geometries around the copper centre are best described as distorted square pyramidal with three nitrogen atoms of tridentate ligand and a chloride ion defining the equatorial planes. The apical positions in the complexes are occupied by a perchlorate O atom in 1 and a chloride ion in 2. Metal directed assembly of infinite two-dimensional supramolecular network stabilizes the crystal structures of both complexes in the solid state. The global magnetic interactions in complexes 1 and 2 are found to be paramagnetic with mueff values of 1.65 BM and 1.63 BM, respectively, which are typical for a Cu(II) d9 system.

Copper-Catalyzed Carbamoylation of Terminal Alkynes with Formamides via Cross-Dehydrogenative Coupling

An efficient approach for direct carbamoylation of terminal alkynes with formamides affording propiolamides has been developed by copper-catalyzed oxidative cross coupling of C(sp)-H and C(sp2)-H bonds in the presence of a pincer ligand with two imidazolyl groups. The catalytic reaction is compatible with diverse functional groups but sensitive to the electronic effect of terminal alkyne and the steric effect of formamides. KIE study indicates the cleavage of the carbamoyl C-H bond affording formamide radical is the rate-determining step.

Demonstration of intramolecular energy transfer in asymmetric bimetallic ruthenium(II) complexes

A new family of bimetallic Ru(ii) complexes derived from an asymmetric bridging ligand (tpy-Hbzim-dipy) consisting of both bipyridine and terpyridine chelating sites covalently connected via phenyl-imidazole spacer were designed in this work to demonstrate intramolecular energy transfer from one component to the other in asymmetric dyads. To fine tune the photo-redox properties, both bidentate and tridentate terminal ligands in the complexes were varied systematically. Both steady state and time-resolved luminescence spectral results indicated photo-induced intramolecular energy transfer from the excited MLCT state of the [(bpy/phen)2RuII(dipy-Hbzim-tpy)] component to the MLCT state of the tpy-containing unit [(dipy-Hbzim-tpy)RuII(tpy-PhCH3/H2pbbzim)] in dyads with rate constant values on the order of 106-107 s-1. Temperature-dependent luminescence studies indicated an enhancement in the luminescence intensity and excited state lifetimes upon decreasing the temperature.

2,6-Bis(2-benzimidazolyl)pyridine receptor for urea recognition

The use of 2,6-bis(2-benzimidazolyl)pyridine as a neutral receptor enables the formation of highly stable supramolecular complexes with urea via self-assembly and which were characterized by spectroscopy and X-ray diffraction analysis. This receptor utilizes the imine nitrogen located on its outer core in addition to the cavity to form hydrogen-bonded adducts with high binding affinity, thus providing a unique design for chemical and biological recognition.

The number of collisions between reactants and catalyst is at a maximum.In a patent, 14220-64-5, name is Bis(benzonitrile)palladium chloride, introducing its new discovery. Application In Synthesis of Bis(benzonitrile)palladium chloride

A series of platinum(II) complexes with tridentate ligands was synthesized and their interactions with Gquadruplex DNA within the c-myc gene promoter were evaluated. Complex 1, which has a flat planar 2,6-bis(benzimidazol-2-yl)pyridine (bzimpy) scaffold, was found to stabilize the c-myc G-quadruplex structure in a cellfree system. An in silico G-quadruplex DNA model has been constructed for structure-based virtual screening to develop new PtII-based complexes with superior inhibitory activities. By using complex 1 as the initial structure for hit-to-lead optimization, bzimpy and related 2,6-bis(pyrazol-3-yl) pyridine (dPzPy) scaffolds containing amine side-chains emerge as the top candidates. Six of the top-scoring complexes were synthesized and their interactions with c-myc G-quadruplex DNA have been investigated. The results revealed that all of the complexes have the ability to stabilize the c-myc G-quadruplex. Complex 3a ([PtIIL2R]+; L2 = 2,6bis[1-(3-piperidinepropyl)-1H-enzo[d]imidazol-2-yl]pyridine, R = Cl) displayed the strongest inhibition in a cell-free system (IC50 = 2.2 muM) and was 3.3-fold more potent than that of 1. Complexes 3a and 4a ([PtIIL3R]+; L3 = 2,6-bis[1-(3-morpholinopropyl)1H- pyrazol-3-yl]pyridine, R = Cl) were found to effectively inhibit c-myc gene expression in human hepatocarcinoma cells with IC50 values of 17 muM, whereas initial hit 1 displayed no significant effect on gene expression at concentrations up to 50 muM. Complexes 3a and 4a have a strong preference for Gquadruplex DNA over duplex DNA, as revealed by competition dialysis experiments and absorption titration; 3a and 4 a bind G-quadruplex DNA with binding constants (K) of approximately 106-107dm 3mol-1, which are at least an order of magnitude higher than the K values for duplex DNA. NMR spectroscopic titration experiments and molecular modeling showed that 4 a binds c-myc G-quadruplex DNA through an external end-stacking mode at the 3’terminal face of the G-quadruplex. Intriguingly, binding of c-myc G-quadruplex DNA by 3b is accompanied by an increase of up to 38-fold in photoluminescence intensity at lambdamax = 622 nm.

The three structures are monomeric and present the Zn cation in a distorted octahedral environment, defined by two chelating tricoordinated ligands at almost right angles to each other. These cationic entities interact with an anionic network composed of hydrogen-bonded pds2- anions and solvate water and DMF molecules via Coulombic forces, and with each other through a number of pi-pi and C=C…pi contacts connecting the aromatic rings. The pds2- anions stabilize the structures in unprecedented counter-ion behaviour.

Metal drugs and the anticancer immune response

The immune system deploys a multitude of innate and adaptive mechanisms not only to ward off pathogens but also to prevent malignant transformation (“immune surveillance”). Hence, a clinically apparent tumor already reflects selection for those malignant cell clones capable of evading immune recognition (“immune evasion”). Metal drugs, besides their well-investigated cytotoxic anticancer effects, massively interact with the cancer-immune interface and can reverse important aspects of immune evasion. This topic has recently gained intense attention based on combination approaches with anticancer immunotherapy (e.g., immune checkpoint inhibitors), a strategy recently delivering first exciting results in clinical settings. This review summarizes the promising but still extremely fragmentary knowledge on the interplay of metal drugs with the fidelity of anticancer immune responses but also their role in adverse effects. It highlights that, at least in some cases, metal drugs can induce long-lasting anticancer immune responses. Important steps in this process comprise altered visibility and susceptibility of cancer cells toward innate and adaptive immunity, as well as direct impacts on immune cell populations and the tumor microenvironment. On the basis of the gathered information, we suggest initiating joint multidisciplinary programs to implement comprehensive immune analyses into strategies to develop novel and smart anticancer metal compounds.
