A Ce(iii) complex potently inhibits the activity and expression of tyrosine phosphatase SHP-2

Four new Ce(iii) complexes 1-4 with tridentate NNO-donor Schiff base ligands have been designed and successfully synthesized. These complexes were characterized by elemental analysis, IR, and ESI-MS, with formulas of [Ce(HL1)(2)(NO3)(3)]2CH(3)OH (1), [Ce(L2)(2)(NO3)]3H(2)O (2), [Ce(HL3)(L3)(NO3)Br]H2O (3) and [Ce(L4)(2)(NO3)]3H(2)O (4), in which ligands HL1-HL4 are respectively N ‘-[(1E)-pyridin-2-ylmethylidene]pyrazine-2-carbohydrazide (HL1), 2-(1-(salicyloylhydrazono)ethyl)pyrazine (HL2), N ‘-[(1E)-pyridin-2-ylmethylidene]pyridine-2-carbohydrazide (HL3) and 2-(1-(salicyloylhydrazono)ethyl) pyridine (HL4). X-ray single crystal diffraction analysis indicates that complex 1 crystallizes in the monoclinic system with the space group C-2/c and the structure of complex 1 consists of a monomeric Ce(iii) species with a Ce(iii) moiety bonded to two tridentate Schiff base ligands, three nitrates and solvents. These complexes effectively inhibit the enzyme activities of PTPs (SHP-1, SHP-2, TCPTP and PTP1B), among which complex 3 shows the most potent inhibition of SHP-2 with the lowest IC50 value of 0.61 mu M and displays obvious selectivity towards SHP-2. Its inhibition potency against SHP-2 was approximately 17, 4, and 5 fold higher than that against SHP-1, TCPTP and PTP1B, respectively. Further study discloses that complex 3 inhibits SHP-2 in a competitive manner. Fluorescence measurements indicate that complex 3 tightly binds to SHP-2 with a molar ratio of 1:1 and a binding constant of 5.45 x 10(5) M-1. Western blot experiments show that complex 3 promotes the phosphorylation of the SHP-2 substrate by the combination of the inhibition of the activity and expression of SHP-2. Moreover, complex 3 decreases the survival rate of A549 cells to 35.12% at 100 mu M and induces apoptosis with an apoptosis rate of 12.06% at 50 mu M. All these results suggest that complex 3 is a potential bi-functional inhibitor of the activity and expression of tyrosine phosphatase SHP-2.

Cobalt Single Atoms on Tetrapyridomacrocyclic Support for Efficient Peroxymonosulfate Activation

Transition-metal catalysts that can efficiently activate peroxide bonds have been extensively pursued for various applications including environmental remediation, chemical synthesis, and sensing. Here, we present pyridine-coordinated Co single atoms embedded in a polyaromatic macrostructure as a highly efficient peroxide-activation catalyst. The efficient catalytic production of reactive radicals through peroxymonosulfate activation was demonstrated by the rapid removal of model aqueous pollutants of environmental and public health concerns such as bisphenol A, without pH limitation and Co2+ leaching. The turnover frequency of the newly synthesized Co single-atom catalyst bound to tetrapyridomacrocyclic ligands was found to be 2 to 4 orders of magnitude greater than that of benchmark homogeneous (Co2+) and nanoparticulate (Co3O4) catalysts. Experimental results and density functional theory simulation suggest that the abundant Tr-conjugation in the polyaromatic support and strong metal-support electronic interaction allow the catalysts to effectively adsorb and activate the peroxide precursor. We further loaded the catalysts onto a widely used poly(vinylidene fluoride) microfiltration membrane and demonstrated that the model pollutants were oxidatively removed as they simply passed through the filter, suggesting the promise of utilizing this novel catalyst for realistic applications.

The water soluble Zn(II) and Mg(II) phthalocyanines: Synthesis, photochemical, DNA photodamage and PDT effects against A549 cells

In this study, the phthalonitrile compound 4-(thieno[3,2-b]pyridin-7-yloxy] phthalonitrile (3), it’s peripherally tetra substituted zinc(II) (4) and magnesium(II) (5) phthalocyanines and their water-soluble derivatives (ZnPcQ) and (MgPcQ) were synthesized. The compounds were characterized with a combination of various spectroscopic techniques. The singlet oxygen quantum yields of ZnPcQ and MgPcQ were determined as 0.59 and 0.36. Their DNA nuclease, photodamage and oxidative photodamage experiments were investigated using agarose gel electrophoresis on supercoiled plasmid pBR322 DNA. The PDT effects of the compounds were investigated using MTT assay toward A549 cells. ZnPcQ and MgPcQ did not have damage effects on supercoiled plasmid pBR322 DNA without irradiation whereas ZnPcQ showed significant photodamage and oxidative photodamage effects upon irradiation. The photodamage mechanism experiments showed that singlet oxygen had a crucial role in the photodamage pathway. MgPcQ did not show considerable cytotoxic and phototoxic effects on A549 cell for 24 h. On the other hand, the cell viability of A549 was 69 +/- 2.70 % at 10 mu M without irradiation in the presence of ZnPcQ. A549 cells treated with 5 and 10 mu M of ZnPcQ upon irradiation, A549 presented 75 +/- 5.90 % and 44 +/- 7.0 % of viabilities, respectively. These results suggested that ZnPcQ is a promising candidate for PDT and worthy of further research.

A Sensitive Fluorescent Turn-on Probe NapP-deap Based on Naphthalimide Derivative to Detect Hg(II) Ions in HEPES Buffer Solution and Living Cells

A highly sensitive fluorescent turn-on probe NapP-deap based on naphthalimide derivative was developed that bound Hg2+ ions rapidly in the N-2-hydroxyethylpiperazine-N-ethane-sulphonic acid(HEPES) buffer solution via photo-induced electron transfer(PET) being inhibited mechanism. The titration experiment displayed that the emission intensity of NapP-deap at 540 nm was almost linearly increased by about 3-fold. The Job’s plot showed a stoichiometry factor of 1:1 of the ligand-to-metal ratio. The detection limit of fluorescent probe was calculated to be 6.2×10(-9) mol/L. H-1 NMR studies could confirm that one Hg2+ ion was bound by the N atoms(a, b) of piperazine or the N atom(c) of pyridine. The fluorescent probe could be used for the detection of Hg2+ ions in living cells.

New Insight of Pyrrole-Like Nitrogen for Boosting Hydrogen Evolution Activity and Stability of Pt Single Atoms

Single atomic Pt catalysts exhibit particularly high hydrogen evolution reaction (HER) activity compared to conventional nanomaterial-based catalysts. However, the enhanced mechanisms between Pt and their coordination environment are not understood in detail. Hence, a systematic study examining the different types of N in the support is essential to clearly demonstrate the relationship between Pt single atoms and N-doped support. Herein, three types of carbon nanotubes with varying types of N (pyridine-like N, pyrrole-like N, and quaternary N) are used as carbon support for Pt single atom atomic layer deposition. The detailed coordination environment of the Pt single atom catalyst is carefully studied by electron microscope and X-ray absorption spectra (XAS). Interestingly, with the increase of pyrrole-like N in the CNT support, the HER activity of the Pt catalyst also improves. First principle calculations results indicate that the interaction between the dyz and s orbitals of H and sp(3) hybrid orbital of N should be the origin of the superior HER performance of these Pt single atom catalysts (SACs).

Design, Synthesis and Characterisation of Novel Phenothiazine-Based Triazolopyridine Derivatives: Evaluation of Anti-Breast Cancer Activity on Human Breast Carcinoma

A series of novel phenothiazine based [1,2,4]triazolo[4, 3-a]pyridine scaffolds were designed and synthesized in good yields by the oxidative cyclisation of phenothiazine pyridylhydrazones. Biological responses of all compounds toward a panel of human breast cancer cells (MDA-MB-231, MDA-MB-468, MCF7, SKBR3 and T47D) and human non-tumorigenic epithelial breast cells (MCF10 A) were evaluated. Structure-activity relationship revealed that compound with pendant phenyl ring on phenothiazine exhibited significant cytotoxic activity and apoptotic induction effects against breast cancer cell line with IC50 value 10.2 to 17.6 mu M. Notably, the cytotoxic effect was 3.5 fold higher on cancer than non-cancer cells, indicating potential control of breast cancer with lower side effects. Molecular docking studies confirmed the presence of hydrophobic contacts between appended phenyl ring, triazolopyridine and phenothiazine moieties with adjacent residues within the binding pocket of tubulin. One of the nitrogen in the triazolo ring also showed hydrogen bonding with tubulin. These tubulin interactions were also found with the taxane ring of paclitaxel. Cell cycle analysis confirmed the G2/M arrest induced by this compound on human breast cancer cells. Therefore, the potential anti-cancer, pro-apoptotic, and cell cycle arrest warrant further development of this molecule as a new class of anticancer agent.

Rational Design of Cycloheptyl-Fused Bis(arylimino)pyridyl-cobalt(II) Precatalysts Adorned with Sterically and Electronically Modified N-Aryls for Enhancing Ethylene Polymerization

The sterically and electronically modified cycloheptyl-fused bis(arylimino)pyridine-cobalt(II) chloride precatalysts [2,3 : 5,6-{C4H8C(N-2,4-(C15H13)-6-R-C6H2}(2)C5HN]CoCl2 (R=Me (Co1), Et (Co2), i-Pr (Co3), Cl (Co4), and F (Co5)) have been prepared via one-pot synthesis approach. All the precatalysts were characterized by elemental analysis, FT-IR spectroscopy and the single-crystal X-ray diffraction for Co2 confirmed distorted-square-pyramidal geometry around the cobalt center. On activation with either MAO (methylaluminoxane) or MMAO (modified methylaluminoxane), all the cobalt precatalysts displayed high catalytic activities for ethylene polymerization with peak performance of 3.47×10(6) g (PE) mol(-1) (Co) h(-1) at 50 degrees C using MAO and 4.53×10(6) g (PE) mol(-1) (Co) h(-1) at 30 degrees C with MMAO. The steric and electronic influence of the ortho-substitutions (R) displayed significant effect on the catalytic activity and molecular weight of the resultant polyethylene. Notably, the precatalyst Co5 (R=F) exhibited high activity, delivering high-molecular-weight (558.17 kg mol(-1)) polyethylene; highlights the beneficial effect of ortho-substituents (R) alongside with dibenzocycloheptyl groups. In addition, analysis of the obtained polyethylene showed strictly linear structure with saturated and unsaturated (vinyl) end groups.

Functionalization of Benzotriazole-Based Conjugated Polymers for Solar Cells: Heteroatom vs Substituents

With the recent remarkable advances in the efficiency of organic solar cells, the need to distill key structure-property relationships for semiconducting materials cannot be understated. The fundamental design criteria based on these structure-property relationships will help realize low-cost, scalable, and high-efficiency materials. In this study, we systematically explore the impact of a variety of functional groups, including nitrogen heteroatoms, fluorine substituents, and cyano groups, on benzotriazole (TAZ)-based acceptor moieties that are incorporated into the conjugated polymers. Specifically, a pyridine heterocycle was used to replace the benzene unit of TAZ, leading to the PyTAZ polymer, and a cyano substituent was added to the benzene of the TAZ unit, resulting in the CNTAZ polymer. The PyTAZ polymer suffers from low mobility and poor exciton harvesting, driven by large and excessively pure domains when blended with PCBM. The inclusion of fluorine substituents, placed strategically along the polymer backbone, can mitigate these issues, as shown with 4FT-PyTAZ. However, when this same approach is used for the cyano-functionalized polymer (CNTAZ), the resulting polymer (4FT-CNTAZ) is overfunctionalized and suffers from impure domains and recombination issues. The cyano group has a larger impact on the TAZ core compared to the nitrogen heteroatom due to the strong electron-withdrawing strength of the cyano group. Because of this, further functionalization of the cyano-based polymers has less fruitful impact on the polymer properties and results in deterioration of the solar cell efficiency. Overall, this work highlights some of the benefits, thresholds, and limitations for functionalization of conjugated polymers for organic solar cells.

Chemo-enzymatic synthesis of adenine substituted nicotinic acid adenine dinucleotide phosphate (NAADP) analogs

Nicotinamide adenine dinucleotide phosphate (NADP) is an indispensable metabolic co-substrate and nicotinic acid adenine dinucleotide phosphate (NAADP) is an important Ca2+ releasing intracellular second messenger. Exploration of the NADP and NAADP interactome often requires the synthesis of NADP derivatives substituted on the adenosine nucleoside. The introduction of the 2′-phosphate of NADP makes the synthesis of substituted NADP derivatives difficult. We have employed recombinant human NAD kinase expressed in E. roll as an enzymatic reagent to convert readily available synthetic NAD derivatives to NADP analogs, which were subsequently transformed into NAADP derivatives using enzyme catalyzed pyridine base exchange. 8-Ethynyl-NADP, 8-ethynyl-NAADP and 5-N-3-8-ethynyl-NAADP were synthesized starting from a protected 8-ethynyladenosine using a combination of chemical and enzymatic steps and the NAADP derivatives shown to be recognized by the sea urchin NAADP receptor at low concentration. Our methodology will enable researchers to produce mono- and bi-substituted NADP and NAADP analogs that can be applied in proteomic studies to identify NADP and NAADP binding proteins.

Dynamic Kinetic Cross-Electrophile Arylation of Benzyl Alcohols by Nickel Catalysis

Catalytic transformation of alcohols via metal-catalyzed cross-coupling reactions is very important, but it typically relies on a multistep procedure. We here report a dynamic kinetic cross-coupling approach for the direct functionalization of alcohols. The feasibility of this strategy is demonstrated by a nickel-catalyzed cross-electrophile arylation reaction of benzyl alcohols with (hetero)aryl electrophiles. The reaction proceeds with a broad substrate scope of both coupling partners. The electron-rich, electron-poor, and ortho-/meta-/para-substituted (hetero)aryl electrophiles (e.g., Ar-OTf, Ar-I, Ar-Br, and inert Ar-Cl) all coupled well. Most of the functionalities, including aldehyde, ketone, amide, ester, nitrile, sulfone, furan, thiophene, benzothiophene, pyridine, quinolone, Ar-SiMe3, Ar-Bpin, and Ar-SnBu3, were tolerated. The dynamic nature of this method enables the direct arylation of benzylic alcohol in the presence of various nucleophilic groups, including nonactivated primary/secondary/tertiary alcohols, phenols, and free indoles. It thus offers a robust alternative to existing methods for the precise construction of diarylmethanes. The synthetic utility of the method was demonstrated by a concise synthesis of biologically active molecules and by its application to peptide modification and conjugation. Preliminary mechanistic studies revealed that the reaction of in situ formed benzyl oxalates with nickel, possibly via a radical process, is an initial step in the reaction with aryl electrophiles.
