SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 293:122501. [PMID: 36801741 DOI: 10.1016/j.saa.2023.122501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 01/25/2023] [Accepted: 02/13/2023] [Indexed: 06/18/2023]
Abstract
Thorium, as a radioactive element, is always associated with rare earth in nature. So it is an exacting challenge to recognize thorium ion (Th4+) in the presence of lanthanide ions because of their overlapping ionic radii. Here three simple acylhydrazones (AF, AH and ABr, with the functional group fluorine, hydrogen and bromine, respectively) are explored for Th4+ detection. They all exhibit excellent "turn-on" fluorescence selectivity toward Th4+ among f-block ions in aqueous medium with outstanding anti-interference abilities, where the coexistence of lanthanide and uranyl ions in addition with other ordinary metal ions have negligible effects during Th4+ detection. Interestingly, pH variation from 2 to 11 has no significant influence on the detection. Among the three sensors, AF displays the highest sensitivity to Th4+ and ABr the lowest with the emission wavelengths in the order of λAF-Th < λAH-Th < λABr-Th. The detection limit of AF to Th4+ can reach 29 nM (pH = 2) with a binding constant of 6.64 × 109 M-2. Response mechanism for AF toward Th4+ is proposed based on the results of HR-MS, 1H NMR and FT-IR spectroscopies together with DFT calculations. This work provides important implications on the development of related series of ligands in nuclide ions detection and future separation from lanthanide ions.

Abstract
Ruthenium(II) complexes of the type [Ru(bpy)2(L1/L2/L3)]PF6 [where bpy = 2,2'-bipyridine, H(L1) = N-(pyrid-2-yl)salicylaldimine (1), H(L2) = N-(6-methylpyrid-2-yl)salicylaldimine (2), and H(L3) = N-(4,6-dimethylpyrid-2-yl)salicylaldimine (3)] have been isolated. The X-ray structures of 1-3 reveal distorted octahedral coordination geometry with a planar ruthenium phenolate moiety. They exhibit interpair dimeric association in their solid state such as (a) π-π-stacking interactions (1-3) and (b) C-H···π interactions (2). The 1H NMR spectral data shed light on the characteristics of metal-ligand bonding and chelate ring conformations. The complexes exhibit strong metal-to-ligand charge-transfer transitions in the visible region. The complexes also undergo two successive metal-based oxidative processes corresponding to the RuII/RuIII and RuIII/RuIV couples. Resonance Raman studies strongly suggest that the lowest unoccupied molecular orbital of 1-3 is localized at the bpy ligand. Absorption, emission, and circular dichroic spectral measurements for 1-3 with calf-thymus DNA reveal a groove binding mode of interaction. Interestingly, all of the complexes exhibit pH-dependent DNA damage, and the pH at which the damage is highest corresponds to the pH conditions of the cancer cells. The DNA damage is in the order of 3 > 2 > 1, in which a hydrolytic mechanism dominates. The protein binding properties of the complexes examined by the tryptophan quenching measurements suggest a static mechanism. The positive ΔH and ΔS values indicate that the force acting between the complexes and bovine serum albumin (BSA) is mainly a hydrophobic interaction, and thus BSA may act as a targeted drug-delivery vehicle for ruthenium(II) complexes (K ∼ 105). It is noteworthy that 3 exhibits selectivity with high cytotoxicity against breast cancer cells (EVSA-T and MCF-7), and its potency is comparable to that of cisplatin.

RSC Adv 2020; 10:38566-38577.

Abstract
Synthesis of hydrazones (1a–4a and 1b–4b), quinazolines (3c·MeOH and 3d·MeOH), and hydrazone-Schiff bases (4c and 4d) is achieved by combining suitable aldehydes (2,3- or 2,4-dihydroxybenzaldehyde) with four hydrazides (isonicotinic, nicotinic, and 2- or 4-aminobenzoic acid hydrazide). A suite of approaches for their preparation is described: solution-based synthesis, mechanosynthesis, and solid-state melt reactions. The mechanochemical approach is generally a better choice for the quinazolines, while the solid-state melt reaction is more efficient for derivatives of (iso)nicotinic based hydrazones. Crystalline amine-functionalised hydrazones 4a and 4b undergo post-synthetic modifications in reactions with 3- or 4-pyridinecarbaldehyde vapours to form hydrazone-Schiff bases 4a-3py, 4b-3py, 4a-4py, and 4b-4py. Mechanochemical and vapour-mediated reactions are followed by ex situ powder X-ray diffraction and IR-ATR methods, respectively. The chemometric analysis of these data using principal component analysis provided an insight into the reaction profiles and reaction times. Azines (5a and 5b), achieved from aldehydes and hydrazine, reversibly change colour in response to temperature changes. The structures of all products are ascertained by a combined use of spectroscopic and X-ray diffraction methods. The cytotoxic and antimicrobial activities of all compounds against selected human cancer cell lines and bacterial strains are evaluated. We compare different routes to prepare hydrazones, quinazolines, and hydrazone-Schiff bases: solution-based, vapor-mediated, mechanochemical, and solid-state melt synthesis.![]()

Abstract
An easy access to a series of N-phenylmorpholine derivatives linked with thiazole or formazan moieties were achieved using simple experimental procedure under conventional and microwaves irradiation conditions. The reaction of 2-(N-phenylmorpholine)ethylidene)hydrazine-1-carbothioamide derivatives and [1-(4-morpholin-4-yl-phenyl)-ethylidene]-hydrazine with a variety of hydrazonoyl chlorides or phenacyl bromide derivatives afforded the corresponding thiazoles or N-substitutedhydrazino-derivatives linked to N-phenylmorpholine moiety in good to excellent yields. The structures of the newly synthesized compounds were fully emphasized and characterized by spectroscopic as well as elemental analyses. The mode of binding of some selected compounds with SS-DNA was evaluated using UV-Vis absorption, and viscosity measurements. The results showed intercalation binding mode of most of the tested compounds. Both antimicrobial and anti-cancer activities have been studied for some selected compounds from synthetic derivatives. Their results showed a remarkable efficacy for some derivatives against both examined microbes and cancer cells.

Abstract
Five new complexes with general formula [Ru(Ln)(PP)(bipy)]PF6, where Ln = N,N'-dimethyl-N-Acyl thiourea, and P-P: 1,2-bis(diphenylphosphino)ethane (dppe) or 1,4-bis(diphenylphosphino)butane (dppb)) were synthesized and characterized by elemental analysis, molar conductivity, cyclic voltammetry, IR, NMR (1H, 13C{1H} and 31P{1H}), and single crystal X-ray diffractometry. The cytotoxicity of compounds against lung and breast tumor cell lines was significant, where two complexes, [Ru(L3)(bipy)(dppe)]PF6 (3) and [Ru(L3)(bipy)(dppb)]PF6 (6), were selected to evaluate changes in morphology, inhibition of migration and cell death in the MDA-MB-231 lineage. The complexes caused alterations in the cell morphology and were able to inhibit cell migration at the concentrations evaluated, induce the cell cycle arrested in the Sub-G1 phase, and induced cell death by apoptosis. All the complexes presented interaction with HSA, and the interaction studies with DNA suggested weak interactions, probably by the minor groove.

Abstract
Background & Objective:
Six novel complexes of transition metal namely,
[CoLCl2(H2O)2]0.5H2O, [NiLCl2(H2O)2]0.5H2O, [CuLCl2]0.5H2O, [ZnLCl2], [PdLCl2]H2O and
[CdLCl2]H2O, where L is benzocycloheptenone thiosemicarbazone ligand, have been obtained. The
confirmation of the structures of the obtained metal chelates depends on the different spectral and
physicochemical techniques including CHN analysis, infrared spectra, molar conductivity measurement,
UV-vis, thermogravimetric analysis and magnetic moment. The infrared spectral results ascertained
that the ligand behaved as neutral bidentate connecting the metal centers via N and S atoms of
C=N and C=S groups, respectively.
Methods:
The UV-Vis, molar conductivity and magnetic susceptibility results implied that the geometrical
structures of the metal chelates are octahedral for Co(II) & Ni(II) complexes, tetrahedral for
Zn(II) & Cd(II) complexes and square planar for Cu(II) & Pd(II) complexes which have been confirmed
by molecular modeling studies.
Conclusion:
Moreover, the mode of interaction between some chosen metal complexes towards SSDNA
has been thoughtful by UV-Vis spectra and viscosity measurements. The value of the intrinsic
binding constant (Kb) for the examined compounds has been found to be lower than the binding affinity
of the classical intercalator ethedium bromide. Also, the viscosity measurements of the complexes
proved that they bind to DNA, most likely, by a non-intercalative mode like H-bonding or electrostatic
interactions.

Abstract
The title Schiff base compound, C14H9BrCl2N2O, displays a trans or E configuration with respect to the C=N bond, with a dihedral angle 15.7 (2)° formed between the benzene rings. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming chains along [001] which enclose R 1 2(6) loops. The inter-molecular inter-actions were investigated by Hirshfeld surfaces analysis and two-dimensional fingerprint plots. The DFT-B3LYP/6-311 G++(d,p) method was used to determine the HOMO-LUMO energy levels.

Abstract
The title Schiff base compound, C15H13BrN2O2, displays an E configuration with respect to the C=N double bond, which forms a dihedral angle of 58.06 (9)° with the benzene ring. In the crystal, the mol-ecules are linked into chains parallel to the b axis by N-H⋯O and C-H⋯O hydrogen bonds, giving rise to rings with an R 2 1(6) graph-set motif. The chains are further linked into a three-dimensional network by C-H⋯π inter-actions. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from C⋯H (33.2%), H⋯H (27.7%), Br⋯H/H⋯Br (14.2%) and O⋯H/H⋯O (13.6%) inter-actions. The title compound has also been characterized by frontier mol-ecular orbital analysis.

Abstract
In this study, we synthesized a novel metal flavonoid complex and investigated its effects on the non-small cell lung cancer cell lines, A549 and toxicity on the human dermal fibroblast cell lines, HDFa. 1H, 13C NMR, single crystal X-ray diffraction and elemental micro analysis (C,H,N,S/O) were used to characterize the synthesized kaempferol-based Ru (II) complex. Cell toxicity was studied using MTT assay and electric cell substrate impedance sensing (ECIS). It was evident from the MTT results that no significant cytotoxicity in HDFa cells occurs with the synthesized complex, but in case of A549 cells, significant cytotoxicity was observed even at low concentrations (10-20 μm). In addition, the effect of the newly synthesized complex on the A549 cell line was studied by investigating the cellular damage via atomic force microscopy and DNA fragmentation assay. The obtained results revealed that the synthesized complex was able to inhibit the cancer cells and have shown moderate anticancer activity against A549 cancer cell lines. In addition, it was evident that the complex was more active than kaempferol and well tolerated by normal cell lines.

Abstract
In recent years, the field of metal-based drugs has been dominated by other existing precious metal drugs, and many researchers have focused their attention on the synthesis of various ruthenium (Ru) complexes due to their potential medical and pharmaceutical applications. The beneficial properties of Ru, which make it a highly promising therapeutic agent, include its variable oxidation states, low toxicity, high selectivity for diseased cells, ligand exchange properties, and the ability to mimic iron binding to biomolecules. In addition, Ru complexes have favorable adsorption properties, along with excellent photochemical and photophysical properties, which make them promising tools for photodynamic therapy. At present, nanostructured materials functionalized with Ru complexes have become an efficient way to administer Ru-based anticancer drugs for cancer treatment. In this review, the recent developments in the nanostructured materials functionalized with Ru complexes for targeted drug delivery to tumors are discussed. In addition, information on "traditional" (ie, non-nanostructured) Ru-based cancer therapies is included in a precise manner.
