GSH-responsive and folate receptor-targeted pyridine bisfolate-encapsulated chitosan nanoparticles for enhanced intracellular drug delivery in MCF-7 cells. Carbohydr Res 2024; 543:109207. [PMID: 39018698 DOI: 10.1016/j.carres.2024.109207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Revised: 07/08/2024] [Accepted: 07/08/2024] [Indexed: 07/19/2024]
Abstract
Folic acid receptor-targeted drug delivery system is a promising candidate for tumor-targeted delivery because its elevated expression specifically on tumor cells enables the selective delivery of cytotoxic cargo to cancerous tissue, thereby minimizing toxic side effects and increasing the therapeutic index. Pyridine bisfolate-chitosan (PyBFA@CS NPs) and folate-chitosan nanocomposite (FA@CS NPs) were synthesized with suitable particle size (256.0 ± 15.0 and 161.0 ± 5.0 nm), high stability (ζ = -27.0 ± 0.1 and -30.0 ± 0.2 mV), respectively, and satisfactory biocompatibility to target cells expressing folate receptors and try to answer the question: Is the metal center always important for activity? Since almost all pharmaceuticals work by binding to specific proteins or DNA, the in vitro binding of human serum albumin (HSA) to PyBFA@CS NPs and FA@CS NPs has been investigated and compared with PyBFA. Strong affinity to HSA is shown by quenching and binding constants in the range of 105 and 104 M-1, respectively with PyBFA@CS NPs showing the strongest. The compounds-HSA kinetic stability, affinity, and association constants were investigated using a stopped-flow method. The findings showed that all formulations bind by a static quenching mechanism that consists of two reversible steps: rapid second-order binding and a more slowly first-order isomerization reaction. The overall coordination affinity of HSA to PyBFA@CS NPs (6.6 × 106 M-1), PyBFA (4.4 × 106 M-1), and FA@CS NPs (1.3 × 106 M-1) was measured and The relative reactivity is roughly (PyBFA@CS NPs)/(PyBFA)/(FA@CS NPs) = 5/3/1. Additionally, in vitro cytotoxicity revealed that, consistent with the binding constants and coordination affinity, active-targeting formulations greatly inhibited FR-positive MCF-7 cells in compared to FRs-negative A549 cells in the following trend: PyBFA@CS NPs > PyBFA > FA@CS NPs. Furthermore, in vitro drug release of PyBFA@CS NPs was found to be stable in PBS at pH 7.4, however, the in pH 5.4 and in pH 5.4 containing 10 mM glutathione (GSH) (mimicking the tumor microenvironment) reached 43 % and 73 %, respectively indicating that the PyBFA@CS NPs system is sensitive to GSH. Folate-modified nanoparticles, PyBFA@CS NPs, are a promising therapeutic for MCF-7 therapy because they not only showed a greater affinity for HSA, but also showed higher cleavage efficiency toward the minor groove of pBR322 DNA via the hydrolytic way, as well as effective antibacterial activity that avoids the usage of extra antibiotics. .

DNA Binding and Cleavage, Stopped-Flow Kinetic, Mechanistic, and Molecular Docking Studies of Cationic Ruthenium(II) Nitrosyl Complexes Containing “NS4” Core. Molecules 2023; 28:molecules28073028. [PMID: 37049792 PMCID: PMC10095794 DOI: 10.3390/molecules28073028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 03/24/2023] [Accepted: 03/24/2023] [Indexed: 03/31/2023] Open
Abstract
This work aimed to evaluate in vitro DNA binding mechanistically of cationic nitrosyl ruthenium complex [RuNOTSP]+ and its ligand (TSPH2) in detail, correlate the findings with cleavage activity, and draw conclusions about the impact of the metal center. Theoretical studies were performed for [RuNOTSP]+, TSPH2, and its anion TSP−2 using DFT/B3LYP theory to calculate optimized energy, binding energy, and chemical reactivity. Since nearly all medications function by attaching to a particular protein or DNA, the in vitro calf thymus DNA (ctDNA) binding studies of [RuNOTSP]+ and TSPH2 with ctDNA were examined mechanistically using a variety of biophysical techniques. Fluorescence experiments showed that both compounds effectively bind to ctDNA through intercalative/electrostatic interactions via the DNA helix’s phosphate backbone. The intrinsic binding constants (Kb), (2.4 ± 0.2) × 105 M−1 ([RuNOTSP]+) and (1.9 ± 0.3) × 105 M−1 (TSPH2), as well as the enhancement dynamic constants (KD), (3.3 ± 0.3) × 104 M−1 ([RuNOTSP]+) and (2.6 ± 0.2) × 104 M−1 (TSPH2), reveal that [RuNOTSP]+ has a greater binding propensity for DNA compared to TSPH2. Stopped-flow investigations showed that both [RuNOTSP]+ and TSPH2 bind through two reversible steps: a fast second-order binding, followed by a slow first-order isomerization reaction via a static quenching mechanism. For the first and second steps of [RuNOTSP]+ and TSPH2, the detailed binding parameters were established. The total binding constants for [RuNOTSP]+ (Ka = 43.7 M−1, Kd = 2.3 × 10−2 M−1, ΔG0 = −36.6 kJ mol−1) and TSPH2 (Ka = 15.1 M−1, Kd = 66 × 10−2 M, ΔG0 = −19 kJ mol−1) revealed that the relative reactivity is approximately ([RuNOTSP]+)/(TSPH2) = 3/1. The significantly negative ΔG0 values are consistent with a spontaneous binding reaction to both [RuNOTSP]+ and TSPH2, with the former being very favorable. The findings showed that the Ru(II) center had an effect on the reaction rate but not on the mechanism and that the cationic [RuNOTSP]+ was a more highly effective DNA binder than the ligand TSPH2 via strong electrostatic interaction with the phosphate end of DNA. Because of its higher DNA binding affinity, cationic [RuNOTSP]+ demonstrated higher cleavage efficiency towards the minor groove of pBR322 DNA via the hydrolytic pathway than TSPH2, revealing the synergy effect of TSPH2 in the form of the complex. Furthermore, the mode of interaction of both compounds with ctDNA has also been supported by molecular docking.

Abstract
Since numerous people annually pass away due to cancer, research in this field is essential. Thus a newly made and water like palladium(II) complex of formula [Pd(phen)(acac)]NO3, where phen is 1,10-phenanthroline and acac is acetylacetonato ligand, has been synthesized by the reaction between [Pd(phen)(H2O)2](NO3)2 and sodium salt of acetylacetone in the molar ratio of 1:1. It has been structurally characterized via the methods such as conductivity measurement, elemental analysis and spectroscopic methods (FT-IR, UV-Vis and 1H NMR). The geometry optimization of this complex at the DFT level of theory reveals that Pd(II) atom is situated in a square-planar geometry. The complex has been screened for its antitumor activity against K562 cancer cells which demonstrated efficacious activity. The interaction of above palladium(II) complex with CT-DNA as a target molecule for antitumor agents and BSA as a transport protein was studies by a variety of techniques. The results of UV-Vis absorption and fluorescence emission indicated that the Pd(II) complex interacts with EB + CT-DNA through hydrophobic and with BSA by hydrogen bonding and van der Waals forces at very low concentrations. In these processes, the fluorescence quenching mechanism of both the macromolecules seems to be the combined dynamic and static. The interaction was further supported for CT-DNA by carrying out the gel electrophoresis and viscosity measurement and for BSA by the circular dichroism and Förster resonance energy transfer experiments. Furthermore, results of partition coefficient determination showed that the [Pd(phen)(acac)]NO3 complex is more lipophilic than that of cisplatin. Moreover, molecular docking simulation confirms the obtained results from experimental tests and reveals that the complex tends to be located at the intercalation site of DNA and Sudlow's site I of BSA.

Abstract
Two nickel(II) complexes with substituted bipyridine ligand of the type [Ni(NN)3](ClO4)2, where NN is 4,4'-dimethyl-2,2'-bipyridine (dimethylbpy) (1) and 4,4'-dimethoxy-2,2'-bipyridine (dimethoxybpy) (2), have been synthesized, characterized, and their interaction with DNA and bovine serum albumin (BSA) studied by different physical methods. X-ray crystal structure of 1 shows a six-coordinate complex in a distorted octahedral geometry. DNA-binding studies of 1 and 2 reveal that both complexes sit in DNA groove and then interact with neighboring nucleotides differently; 2 undergoes a partial intercalation. This is supported by molecular-docking studies, where hydrophobic interactions are apparent between 1 and DNA as compared to hydrogen bonding, hydrophobic, and π-π interactions between 2 and DNA minor groove. Moreover, the two complexes exhibit oxidative cleavage of supercoiled plasmid DNA in the presence of hydrogen peroxide as an activator in the order of 1 > 2. In terms of interaction with BSA, the results of spectroscopic methods and molecular docking show that 1 binds with BSA only via hydrophobic contacts while 2 interacts through hydrophobic and hydrogen bonding. It has been extensively demonstrated that the nature of the methyl- and methoxy-groups in ligands is a strong determinant of the bioactivity of nickel(II) complexes. This may justify the above differences in biomolecular interactions. In addition, the in vitro cytotoxicity of the complexes on human carcinoma cells lines (MCF-7, HT-29, and U-87) has been examined by MTT assay. According to our observations, 1 and 2 display cytotoxicity activity against selected cell lines. Communicated by Ramaswamy H. Sarma.

Abstract
Four copper(II) complexes, 1-4 containing regioisomeric vanillin Schiff base derivatives and the nonsteroidal anti-inflammatory drug (NSAID), naproxen, were synthesised and characterised. All complexes effectively cleave DNA in cell-free systems, with 4 displaying the highest nuclease activity. DNA binding studies suggest that 4 binds to DNA via the grooves prior to inducing oxidative DNA cleavage. Three of the complexes (1, 3, and 4) indiscriminately kill cancer stem cell (CSC)-enriched cells (HMLER-shEcad) and bulk cancer cells (HMLER) at micromolar concentrations. The most effective complex, 4 also reduced the formation and size of mammospheres to a similar extent as salinomycin, a well-established CSC-potent agent. Mechanistic studies show that 4 is readily taken up by CSCs, elevates intracellular reactive oxygen species (ROS) levels, causes DNA damage, and induces caspase-dependent apoptosis. Furthermore, 4 inhibits cyclooxygenase-2 (COX-2) expression and causes COX-2-dependent CSC death. The advantage of 4 over bulk cancer cell- or CSC-selective agents is that it has the potential to remove whole tumor populations (bulk cancer cells and CSCs) with a single dose.

Abstract
The compound N-(2-hydroxybenzylidene)-1-ethyl-1, 4-dihydro-7-methyl-4-oxo-1, 8 naphthyridine-3-carbohydrazide (LH) and its Cu (II), Co (II) and Zn (II) complexes were synthesized and characterized. The absorption spectral titrations and competitive DNA binding studies depicted those complexes of title compound bind to CT-DNA through intercalation. Interestingly [Cu (II)-(L2)] showed relatively high binding constant value (6.61 x 10(5) M(-1)) compared to [Co (II)-(L2)] (4.378× 10(5) M(-1)) and [Zn (II)-(L2)] (3.1x10(5) M(-1)). Ligand and its complexes were also examined for DNA nuclease activity against pBR-322 plasmid DNA, which showed that [Cu (II)-(L2)] had the best hydrolytic cleavage property displaying prominent double-strand DNA cleavage. In addition, antioxidant activities of the ligand and its metal complexes investigated through scavenging effects for DPPH radical in- vitro, indicated their potentiality as good antioxidants. The in vitro anti-bacterial study inferred the better anti-bacterial activity of [Cu (II)-(L2)] and this was also correlated theoretically by employing docking studies wherein [Cu (II)-(L2)] displayed good Gold score and Chem score. Finally the in vitro anti- proliferative activity of studied compounds was tested against HeLa and MCF-7 cell lines. Interestingly [Cu (II)-(L2)] displayed lower IC50 value and lower percentage of viability in both HeLa and MCF-7 cell lines.

Abstract
This work was focused on a study of the DNA binding and cleavage properties of lomefloxacin (LMF) and its ternary transition metal complexes with glycine. The nature of the binding interactions between compounds and calf thymus DNA (CT-DNA) was studied by electronic absorption spectra, fluorescence spectra and thermal denaturation experiments. The obtained results revealed that LMF and its complexes could interact with CT-DNA via partial/moderate intercalative mode. Furthermore, the DNA cleavage activities of the compounds were investigated by gel electrophoresis. Mechanistic studies of DNA cleavage suggest that singlet oxygen ((1)O2) is likely to be the cleaving agent via an oxidative pathway, except for Cu(II) complex which proceeds via both oxidative and hydrolytic pathways. Antimicrobial and antitumor activities of the compounds were also studied against some kinds of bacteria, fungi and human cell lines.

Evaluation of DNA Binding, Cleavage, and Cytotoxic Activity of Cu(II), Co(II), and Ni(II) Schiff Base Complexes of 1-Phenylindoline-2,3-dione with Isonicotinohydrazide. Bioinorg Chem Appl 2014; 2014:215392.

Abstract
One new series of Cu(II), Co(II), and Ni(II) Schiff base complexes was prepared through the condensation reaction between 1-phenylindoline-2,3-dione with isonicotinohydrazide followed by metalation, respectively. The Schiff base ligand(L), (E)-N'-(2-oxo-1-phenylindolin-3-lidene)isonicotinohydrazide, and its complexes were found soluble in DMF and DMSO solvents and characterized by using the modern analytical and spectral techniques such as elemental analysis, conductivity, magnetic moments, IR, NMR, UV-visible, Mass, CV, and EPR. The elemental analysis data of ligand and their complexes were well agreed with their calculated values in which metal and ligand stoichiometry ratio 1 : 2 was noted. Molar conductance values indicated that all the complexes were found to be nonelectrolytes. All the complexes showed octahedral geometry around the central metal ions. Herein, we better characterized DNA binding with the complexes by UV-visible and CD spectroscopy and cyclic voltammetry techniques. The DNA cleavage experiments were carried out by Agarose gel electrophoresis method and the cytotoxicity experiments by MTT assay method. Based on the DNA binding, cleavage, and cytotoxicity studies, Cu and Ni complexes were found to be good anticancer agents against AGS-human gastric cancer cell line.

Abstract
New tetrapeptide complexes Cu(II)·Ala-Pro-Ala-Pro (1) and Zn(II)·Ala-Pro-Ala-Pro (2) were synthesized from the reaction of tetrapeptide, Ala-Pro-Ala-Pro and CuCl2/ZnCl2 and were thoroughly characterized by elemental analysis, IR,(1)H and (13)C NMR (in case of 2), ESI-MS, UV and molar conductance measurements. The solution stability study was carried out employing UV-vis absorption titrations over a broad range of pH which suggested the stability of the complexes in solution. In vitro interaction of complexes 1 and 2 with CT-DNA was studied employing UV-vis, fluorescence, circular dichroic and viscometry studies. To throw insight into molecular binding event at the target site, UV-vis titrations of 1 and 2 with mononucleotides of interest viz.; 5'-GMP and 5'-TMP were carried out. Cleavage activity of the complexes with pBR322 plasmid DNA was evaluated by agarose gel electrophoresis and, the electrophoresis pattern demonstrated that both the complexes 1 and 2 are efficient cleavage agents. Further, the Cu(II) complex displayed efficient oxidative cleavage of supercoiled DNA while various reactive oxygen species are responsible for the cleavage in Zn(II) complex.
