A novel chemosensor for the distinguishable detections of Cu2+ and Hg2+ by off-on fluorescence and ratiometric UV-visible absorption

A novel dual-functional chemosensor, derived from the conjugation of rhodamine B with a quinoline derivative (RHQ), was firstly synthesized with high efficiency and cost-effectiveness for the distinguishable detections of Cu2+ and Hg2+ via ring-opening and ring-forming mechanism. The chemosensor exhibits highly selective and distinguishable responses for Cu2+ and Hg2+ in CH3CN-H2O (4:1, v/v) with off-on fluorescence and ratiometric ultraviolet-visible (UV-Vis) absorption changes. Additionally, Cu2+ is identified by opening a rhodamine spirocycle with a UV-Vis absorption band, at around 560 nm and fluorescence turn-on. Interestingly, Hg2+ is discerned by opening the rhodamine spirocycle and by generating a new special cycle for the quinoline unit. Resultantly, there were two UV-Vis absorption bands at around 365 nm and 560 nm, which were accompanied by fluorescence turn-on. Moreover, the chemosensor can quantitatively detect Cu2+ and Hg2+ by off-on fluorescence and ratiometric UV-Vis absorption changes, respectively. Furthermore, the chemosensor with low cytotoxicity could be successfully administered to monitor Cu2+ and Hg2+ in living cells. This work may pay the way for the development of dualfunctional chemosensor for quantificationally detecting metal ions in environmental and biological systems. (C) 2020 Elsevier B.V.

Copper-catalyzed [3+2+1] annulation of anthranils with phenylacetaldehydes: Synthesis of 8-acylquinolines

A Cu-0-catalyzed protocol is proposed for the synthesis of 8-acylquinolines through a [3+2+1] annulation starting from anthranils and phenylacetaldehydes. This protocol is of particular interest in preparing 8-aldehyde quinolines, which have been hard to access so far. Both AgOTf and dioxygen played an important role in the reaction. C3-heterocycle or phenylethylene substituted anthranils could also be employed in the reaction. An interesting esterification of aldehyde was observed.

delta-Regioselective heteroarylation of free alcohols through 1,5-hydrogen-atom transfer

An efficient silver-catalyzed d-regioselective C(sp(3))-H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp(2))-H alkylation products in 31-89% yields. Notably, all types (1 degrees, 2 degrees, and 3 degrees) of d-C(sp(3))-H bonds in the alcohols could be regioselectively activated. This protocol provides a platform to access divergent functionalizations of alcohols and heteroaryls by forming the challenging d-selective C(sp(3))-C(sp(2)) bond.

8-Hydroxyquinoline platinum(ii) loaded nanostructured lipid carriers: synthesis, physicochemical characterization and evaluation of antitumor activity

Every year the incidence of cancer and the death rate are increasing worldwide. The drug 8-hydroxyquinoline platinum(ii) [PtCl(8-O-quinoline)(dmso)] (8HQ-Pt) has been identified as a promising antitumor complex. Nanostructured lipid carriers (NLC) are second-generation drug nanocarrier systems that have superior advantages over other kinds of colloidal carrier systems. 8HQ-Pt compound loaded NLC formulations of cetyl esters (SS) were synthesized via ultrasonication in the presence of two different liquid oils: capric triglyceride, or olive oil. The physicochemical and microscopic characterizations of NLC were analyzed via dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and X-ray diffraction analysis (XRD). In vitro drug release and cytotoxicity, cell uptake and apoptosis assays against the human colon cancer cell line HT-29 were investigated. The results showed that NLCs indicated a narrow size distribution and a mean particle diameter in the range of 136-159 nm. The thermal characteristic analysis confirmed the stability of NLCs up to 185 degrees C. Encapsulation efficiencies of the 8HQ-Pt compound in NLCs were about 80% and the 8HQ-Pt compound in the formulations showed a controlled release profile during 72 h. The release profiles of these two different formulations and the antitumor effect on the HT-29 cell line were compared with those of the free 8HQ-Pt compound. The cellular uptake of two different NLC groups was proved by fluorescence microscopy and the presence of capric triglyceride liquid oil in the formulation increased the intracellular drug delivery capacity when compared with olive oil.

Metal-Free Synthesis and Photophysical Properties of 1,2,4-Triarylpyrroles

A three-component reaction has been developed for the construction of multiaryl-substituted pyrrole derivatives from arylketones, amines, and nitrovinylarenes under metal- free conditions. Hence, homologous 1,2,4-triaryl-substituted pyrrole products were obtained in good to high yields. Furthermore, 2,3,5-triaryl-substituted pyrroles were selectively formed in the absence of nitrovinylarenes. The photophysical properties of some pyrrole products have been investigated to show good aggregation-induced emission (AIE) activity.

Construction of a Quinoline-based Sequential Functioning Chromogenic Sensor for Copper(II) Ion and Biothiols: Its Application to Test Strips

A new compound BQ ((1E,1’E)-N,N’-((1,3-phenylenebis(oxy))bis(3,1-phenylene))bis(1-(quinolin-2-yl)methanimine)) containing quinoline moiety has been developed as a sequential functioning chromogenic sensor for copper(II) ion and biological thiols (GSH, Cys, and Hcy). BQ had a clear chromogenic response toward only copper ion with a red-shifted absorption. Detection limit for copper(II) ion was calculated to be 1.20 mu M. Its application was successfully conducted in test strips. The resultant BQ-Cu2+ complex could detect the biological thiols, showing the color change and blue-shifted absorption via the demetallation of copper(II) ion. The possible binding mechanisms of BQ to copper(II) ion and of BQ-Cu2+ to biological thiols were understood by UV-vis titrations, Job plot, ESI-MS, and H-1 NMR titrations.

Synthesis and gas permeation properties of tetraoxidethianthrene-based polymers of intrinsic microporosity

A series of nine polymers of intrinsic microporosity (PIMs) derived from different bis-catechol monomers and 2,3,7,8-tetrafluoro-5,5 ‘,10,10 ‘-tetraoxidethianthrene (TOT) were synthesised and tested for their potential use as gas separation membranes. As powders, they demonstrate significant nitrogen adsorption at 77 K allowing apparent BET surface areas ranging from 432-785 m(2) g(-1) to be calculated. Six of the polymers were found to be soluble in quinoline facilitating the casting of self-standing films to allow the assessment of their gas separation properties. Spirobifluorene-based polymers exhibited the highest gas permeability, approaching the performance of the archetypal PIM-1, and the data for some are placed close to the 2008 Robeson upper bounds for O-2/N-2 and CO2/CH4. Ageing studies showed a gradual decrease in permeability, accompanied by an increase in selectivity that moved the data more-or-less parallel to the Robeson upper bounds. The two polymers with the lowest and highest gas permeability were both tested over the temperature range 25-55 degrees C and an enhancement in permeability for all gases, with the exception of CO2, was observed along with decreased selectivity for almost all gas pairs. The latter seems to be due to the simultaneous drop in both diffusivity selectivity and solubility selectivity for all gas pairs, but especially those involving CO2, due to a strong decrease in solubility with increasing temperature. The analysis of the energetic and entropic selectivity provides further insight into the remarkable transport properties of PIMs. Overall, the tetraoxidethianthrene unit proves to be a suitable building block for use in PIM synthesis for applications in gas separation membranes and these PIMs have a one to two orders of magnitude higher permeability than more common polysulfones.

A fast-response turn-on quinoline-based fluorescent probe for selective and sensitive detection of zinc (II) and its application

A readily available Schiff base quinoline derivative, quinoline-2-carboxaldehyde (pyridine-2-carbonyl)-hydrazine (QCPCH), has been synthesized via a one-step condensation reaction. It is used as a turn-on fluorescent probe for detecting Zn2+ with high selectivity, sensitivity, and rapid response time of less than 3 s. In addition, the probe QCPCH shows a low detection limit of 72 nM and a large linear detection range (0-180 mu M). The mechanism of probe QCPCH for sensing Zn2+ is proposed to be based on the combined effects of chelation-induced enhanced fluorescence (CHEF) and inhibiting photoinduced electron transfer (PET); this is further demonstrated by the Job’s plot analysis, Benesi-Hilde-brand study, FT-IR spectrum, and H-1 NMR titration. Furthermore, the QCPCH is successfully applied to determine Zn2+ in real water samples, and is made into test strips for fast, convenient, quantitative and qualitative detection of Zn2+.
