General and efficient approaches for the synthesis of new 5-amino and 5-iminoimidazo[1,2-a] imidazoles were developed through a three-component reaction of 1-unsubstituted 2-aminoimidazoles with various aldehydes and isocyanides mediated by zirconium(IV) chloride. The protocols were established considering the reactivity of the starting substrate, which varies depending on the presence of a substituent on the 2-aminoimidazole moiety. A library of new N-fused ring systems with wide structural diversification, novel synthetic, and potential pharmacological interest was obtained in moderate to good yields.

The enantiopure Schiff bases (RorS)-1-(p-R-1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamine (R-1= H and OCH3) are synthesized from reaction between the 2-benzoyl-pyridine andchiral-amine (RorS)-1-(p-R-1-C6H4)ethylamine, respectively. These Schiff bases react with the copper(II) acetate to give distorted-tetrahedralbis[(RorS)-1-(p-R-1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamino-kappa N-2,N]-Delta/?-Cu(PF6)(2)in the presence of NH4PF6. A conformational change fromcis- totrans-isomer occurs in solution and thereby, the copper(II) coordinates to the solelytrans-form to provide the complexes. Cyclic voltammograms demonstrate two quasi-reversible one electron charge transfer processes for the Cu2+/Cu(+)and Cu+/Cu(0)couples in acetonitrile. ECD spectra reveal expected mirror-image relationships and indicate enantiopurity or enantiomeric excess of theRorS-ligands and their associated complexes in solution. Comparisons of experimental and simulated ECD spectra suggest induced chirality at-metal center, which diastereoselectively provides the Delta-Cu-Ror ?-Cu-Sdiastereomer as major product in solution. DFT/TDDFT optimized structures and excited state properties correspond well to the experimental results.

Three hydroxymethyl bridged Cu(ii) complexes of a pyridoxal Schiff base ligand 4-((E)-(2-(pyridin-2-yl)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (LH) have been synthesized and characterized on the basis of spectroscopic, elctrochemical and structural properties. The X-ray crystal structures of the complexes reveal dual denticity of the ligand, bidenticity in the absence of a co-ligand as in complex1, and tridenticity in the presence of a co-ligand such as SCN-/N(CN)(2)(-)as in complexes2and3. The complexes, though binuclear in the solid state, exist as a monomeric unit in solution due to the exceptionally long axial Cu-O-hydroxymethyl(2.4-2.5 angstrom) bond. All three complexes show efficient catalytic activities towards the aerial oxidation of 3,5-ditertiarybutylcatechol (DTBCH2) withk(cat)values of 5.38 x 10(4)h(-1), 1.18 x 10(5)h(-1)and 1.06 x 10(5)h(-1)in methanol. Complexes1and2also act as a selective sulphide ion sensor withK(b)values of 6.6 x 10(3)M(-1)and 8.1 x 10(3)M(-1), respectively, while their respective L.O.D. values are 3.4 mu M and 3.2 mu M.

The Ag/AgBr/TiO2 ternary component nanotube as a heterogeneous photocatalyst was used for the solvent-free oxidation of the benzylic C(sp(3))-H bond to the corresponding carbonyl compound or the solvent-controlled selective oxidative cleavage of the CQC double bond of styrene to benzaldehyde under visible light at room temperature. A wide variety of carbonyl compounds were successfully synthesized through the developed photocatalytic process. Several advantages such as solvent-free conditions, sans additional oxidant, simple reaction, short reaction time, and easy separation of the product promote the reaction to be green. Moreover, the Ag/AgBr/TiO2 nanotubes could be used several times without reduction in their photocatalytic activity.

A series of bidendate pyridine-functionalized metal N-heterocyclic carbene (NHC) complexes with various wingtip substituents (R = methyl, phenyl and tert-butyl) had been prepared from silver oxide-mediated transmetalation method. The basic backbone of the NHC ligands were prepared in two step-wise reactions: reduction of the commercially available 2-benzoylpyridine, followed by halogenation to yield 2-(chloro(phenyl) methyl) pyridine. Subsequent reactions with different imidazoles gave the desired imidazolium salts (or NHC precursors) with different R groups at the N wingtip (R = Me, Ph, t-Bu). Transmetalation of the imidazolium salts into platinum NHC complexes were achieved by using Ag2O mediated method with Pt(cod)Cl-2 as the transmetalating agent. On the other hand, nickel NHC complexes were obtained via one pot synthesis method with nickel chloride as the transmetalating agent and reflux in the presence of a base. Following recrystallisation, the molecular structure of Pt NHC complex (+/-)-5a had been successfully elucidated via single crystal X ray diffraction (XRD) analysis. The six-membered ring of the platinum NHC complexes adopted a boat conformation with the phenyl ring arranged at the axial position. Meanwhile, two unexpected nickel complexes, i.e. a simple nickel coordination complex and a nickelate complex, were obtained and studied using XRD. These Pt NHC complexes and unexpected Ni complexes were evaluated for their in vitro antimicrobial and anticancer activities against a panel of pathogenic microorganisms and three selected human cancer cell lines, including breast (MCF7), colon (HCT116) and oral (H103) cancer cells. Generally, the Pt NHC complexes displayed enhanced antimicrobial activities upon coordination to metals, as compared to the corresponding imidazolium salts i.e. NHC precursors, with minimum inhibitory concentration (MIC) values in micromolar (mM) range. A couple of platinum NHC complexes synthesized exhibited antimicrobial activities with MIC as low as 2 mM, which are comparable to silver NHC complexes with renowned antimicrobial profiles. Similarly, upon coordination to the metals, the cytotoxic effects of the platinum NHC complexes increased significantly as compared to the imidazolium salts. Among all, platinum NHC complex (+/-)-5c displayed significant cytotoxicities towards the cancer cells with IC50 values that are two to three times lower than that of the anticancer drug cisplatin. In summary, evidences for influence of both wingtip substituents and metals on the biological activities of the complexes have been found. (C) 2019 Elsevier B.V. All rights reserved.

Introduction: colorectal cancer (CRC) continues to be difficult to diagnose due to the lack of reliable and predictive biomarkers. Objective: to identify blood-based biomarkers that can be used to distinguish CRC cases from controls. Methods: a workflow for untargeted followed by targeted metabolic profiling was conducted on the plasma samples of 26 CRC cases and ten healthy volunteers (controls) using liquid chromatography-mass spectrometry (LCMS). The data acquired in the untargeted scan was processed and analyzed using MarkerViewt software. The significantly different ions that distinguish CRC cases from the controls were identified using a mass-based human metabolome search. The result was further used to inform the targeted scan workflow. Results: the untargeted scan yielded putative biomarkers some of which were related to the folate-dependent one-carbon metabolism (FOCM). Analysis of the targeted scan found the plasma levels of nine FOCM metabolites to be significantly different between cases and controls. The classification models of the cases and controls, in both the targeted and untargeted approaches, each yielded a 97.2% success rate after cross-validation. Conclusion: we have identified plasma metabolites with screening potential to discriminate between CRC cases and controls.

behavior of cucurbituril-bipyridinium pseudorotaxane ligand by utilizing meta-functionalized bipyridinium dicarboxylate guest. A tailored pseudorotaxane precursor involving 1,1′-(hexane-1,6-diyl)bis(3-cyanopyridin-1-ium) bromide (C6BPCN3) and cucurbit[6]uril (CB[6]) has designed and synthesized. Through in situ hydrolysis of the pseudorotaxane ligands and their coordination assembly with uranyl cations, seven new uranyl-rotaxane coordination polymers URCP1-URCP7 have been obtained under hydrothermal conditions in the presence of different anions. It is demonstrated that the variation of carboxylate groups from para- to meta-position greatly affected the coordination behaviors of the metafunctionalized pseudorotaxane linkers, which are enriched from simple guest-only binding to host-guest simultaneous coordination and synergistic chelating. This effective regulation on uranyl coordination of supramolecular pseudorotaxane can be attributed to the proximity effect, which refers to the meta-position carboxyl group being spatially closer to the portal carbonyl group of CB[6]. Moreover, by combining other regulation methods such as introducing competing counterions and modulating solution acidity, the nuclearity of the uranyl center and the coordination patterns of the pseudorotaxane ligand can be diversely tuned, which subsequently exert great influence on the final dimensionality of resultant uranyl compounds. This work presents a large diversity of uranyl-based coordination polyrotaxane compounds with fascinating mechanically interlocked components and, most importantly, provides a feasible approach to adjust and control the metal coordination behavior of the pseudorotaxane ligand that might expand the scope of application of such supramolecular ligands.
