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.

Influence of the Fluorinated Aromatic Fragments on the Structures of the Cadmium and Zinc Carboxylate Complexes Using Pentafluorobenzoates and 2,3,4,5-Tetrafluorobenzoates as Examples

A series of the cadmium and zinc carboxylate complexes with anions of pentafluorobenzoic (HPfbz) and 2,3,4,5-tetrafluorobenzoic (HTfbz) acids and N-donor ligands (1,10-phenanthroline (Phen) and quinoline (Quin)), [Cd(Pfbz)(2)(Phen)](n) (I), [Cd(Pfbz)(2)(Phen)(2)].2MeCN (II), [Zn(H2O)-(Pfbz)(2)(Phen)] (III), [Zn2Cd(Pfbz)(6)(Phen)(2)].2C(6)H(6) (IV), [Cd-2(H2O)(2)(Tfbz)(4)(Phen)(2)] (V), [Cd-2-(H2O)(2)(Tfbz)(4)(Quin)(2)] (VI), and [Cd(Tfbz)(2)(Phen)(2)].HTfbz (VII), is synthesized. The structures of new complexes I-VII are determined by X-ray diffraction analysis (CIF files CCDC nos. 1871300, 2005461, 2005462, 2005464, 2005466, 2005465, and 2005459, respectively). The majority of the synthesized compounds is typical of intramolecular stacking interactions between the coordinated molecules of the aromatic N-donor ligands and fluorinated substituents of the carboxylate anions. These interactions lead to the formation of unusual compounds, which are different in the cases of pentafluorobenzoates and tetrafluorobenzoates, in particular, coordination polymer I and binuclear complexes V and VI with coordinated water molecules. The synthesized zinc and cadmium compounds differ in structure and composition.

Synthesis of Quinoline-4-carboxamides and Quinoline-4-carboxylates via a Modified Pfitzinger Reaction of N-Vinylisatins

A synthetic approach for the accelerated assembly of quinoline-4-carboxamide and quinoline-4-carboxylate nuclei is presented. The methodology is based on the rearrangement of N-vinylisatins promoted by different types of amines (or ethanol) in a Pfitzinger-type mechanism that, in turn, builds the quinoline ring system. The reaction took place only by heating the starting materials in ethanol, without any additive.

Synthesis, spectral characterization and photophysical studies of tetrahydroquinolines

A metal-free, ultrasound-assisted, fast synthesis of fluorescent N-Boc-protected 1,2,3,4-tetrahydroquinolines 9a-p is described through carbanion-induced ring transformation of 6-aryl-2H-pyran-2-ones 7 with tent-butyl 3-oxopiperidine-l-carboxylate 8 under basic condition. The reaction products 9a-p were isolated in high yields. Our synthetic approach is flexible for introducing electron-withdrawing and electron-donating groups. All the synthesized 1,2,3,4-tetrahydroquinolines 9a-p showed blue fluorescence in the range of 422-470 nm. Based on the optical behavior of compounds 9a-p, we calculated stokes shift, quantum yield and optical band gap which are highly influenced by the substituents in the ring. (C) 2020 Elsevier B.V.

Cyclopalladated benzo[h]quinolinate complexes based on stabilized phosphonium-phosphine ylides: Synthesis, characterization, and application as catalyst in aqueous-phase Suzuki-Miyaura reaction

A series of heteroleptic mononuclear cyclopalladated benzo[h]quinolinate complexes of general formula [Pd(bzq)(Ph2PCH2PPh2C(H)C(O)C6H4-p-R)ClO4 (bzq = 7,8-benzoquinoline; R = Cl (C-1), Br (C-2), NO2 (C-3), OCH3(C-4)), were synthesized by the reaction of [Pd(bzq)(mu-Cl)](2) with 0.5 equiv of phosphorus ylides [Ph2PCH2PPh2C(H)C(O)C6H4-p-R] in CH2Cl2 solvent at room temperature. Bridge splitting with stabilized phosphorus ylides afforded new mononuclear palladacycle derivatives with two five-membered rings. The formation of the complexes was ascertained by elemental analysis, IR, UV-visible and NMR spectroscopic methods. All of the complexes exhibited absorption bands at high energy due to the intraligand transitions [(IL)-I-1 pi ->pi*] and absorptions at lower energy, which are attributed to MLCT transition [(Pd,4d) pi ->pi* (bzq)]. The influence of the R substituent and different solvents on the UV-visible absorption of all complexes was also investigated. Furthermore, palladacycle C-3 was employed as an efficient catalyst in the Suzuki-Miyaura coupling reactions of various aryl halides and phenylboronic acids in the mixed EtOH/H2O media.

3-(4-Carboxybenzoyl)quinoline-2-carboxaldehyde labeling for direct analysis of amino acids in plasma is not suitable for simultaneous quantification of tryptophan, tyrosine, valine, and isoleucine by CE/fluorescence

Capillary electrophoresis coupled to LED-induced fluorescence detection is a robust and sensitive technique used for amino acids (AA) analysis in biological media, after labeling with 3-(4-carboxybenzoyl)quinoline-2-carboxaldehyde (CBQCA). We wanted to quantitate in plasma tryptophan (Trp), tyrosine (Tyr), valine (Val), and isoleucine (Ile). Among the different labeled AA-CBQCA, Trp has the lowest fluorescence yield, which makes its detection and quantification very difficult in biological samples such as plasma. We tried to improve Trp analysis by CE/LED-induced fluorescence detection to its maximal sensitivity by using large volume sample stacking as a preconcentration step in our analytical protocol. At pH 9.5, this step caused a drop in resolution during the separation of the four AAs and it was therefore necessary to work at pH 10. We have found that Tyr, Val, Ile, and Trp are detected and well separated from the other AAs, but Trp cannot be quantified in plasma samples, mainly because of the low fluorescence yield of the Trp-CBQCA derivative. The recorded LOD is 0.18 mu M for Trp-CBQCA in standard solution with a resolution between Trp and Tyr of 1.2, while the LOD is 6 mu M in plasma with the same resolution. Trp, Tyr, Val, and Ile are, however, efficiently quantified when using a 3 M acetic acid electrolyte and CE associated with capacitively coupled contactless conductivity detection, which also has the advantage of not requiring derivatization or large volume sample stacking. This article demonstrates, for the CE user, that quantitative analysis of these four AA in mouse plasma can be performed by CE-fluorescence after CBQCA labeling, with the exception of Trp. It can be advantageously replaced by CE/capacitively coupled contactless conductivity detection, the only efficient one for Trp, Tyr, Val, and Ile quantification. In this case, the LOD for Trp is 2 mu M. The four AAs are separated with resolution with neighbors above 1.5.

Waste-minimized synthesis of C2 functionalized quinolines exploiting iron-catalysed C-H activation

Herein we present an efficient and regioselective iron-catalyzed methodology for the external oxidant-free functionalization of quinoline-N-oxides. The protocol, based on the use of inexpensive and easily accessible FeSO4, showed broad applicability to a wide range of substrates. An additional green feature of this synthetic methodology is H2O being the only by-product. Experimental and computational investigations provide support to a mechanism based on a facile C-H activation event. The green efficiency of the process has also been carefully assessed using: (i) metrics related to the synthetic process (AE, Yield, 1/SF, MRP and RME); (ii) safety/hazard metrics (SHZI and SHI); and (iii) metrics related to the metal used as the catalyst (Abundance, OEL and ADP). In addition to the many advantages of this protocol related to the green iron catalyst used and the safety/hazard features of the process, an E-factor value of ca. 0.92 (84 to >99% reduction compared to known protocols) evidently confirms the sustainable efficiency of the procedure presented. Practical utility has also been demonstrated by performing the reaction efficiently on a multi-gram scale.
