Abstract
Six silver hexafluoroantimonate complexes (1-6) with 4'-(4'-substituted-phenyl)-2,2':6',2''-terpyridine compounds bearing hydrogen (L1), methyl (L2), methylsulfonyl (L3), chloro (L4), bromo (L5) and iodo (L6) were prepared and characterized by 1H NMR, 13C NMR, IR, elemental analysis and single crystal X-ray diffraction. All the compounds exhibit interesting photoluminescence properties in the solid state and solution. In vitro data demonstrate that all of them show higher antiproliferative activities than cisplatin against three human carcinoma cell lines, A549, Eca-109 and MCF-7. Compound 3 exhibits the lowest IC50 value (2.298 μM) against A549 cell lines, which is 2.963 μM for 4 against Eca-109 and 1.830 μM for 1 against MCF-7. For silver halogen-substituted terpyridine compounds, their anticancer activities decrease following the sequence of -Cl, -Br, and -I substituents. The comparison results show that their anticancer activity is significantly higher than that of their free ligands. The DNA interaction was studied by fluorescence titration, circular dichroism spectroscopy and molecular modeling methods. Spectrophotometric results reveal that the compounds have strong affinity binding with DNA as intercalators and molecular docking studies indicate that the binding is contributed by the π-π stacking and hydrogen bonds. The DNA binding ability of the complexes has been correlated with their anticancer activities, which could potentially provide a new rationale for the future design of terpyridine-based metal complexes with antitumor potential.

A New Concept of Enhancing the Anticancer Activity of Manganese Terpyridine Complex by Oxygen-Containing Substituent Modification. Int J Mol Sci 2023; 24:ijms24043903. [PMID: 36835315 PMCID: PMC9963696 DOI: 10.3390/ijms24043903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 01/31/2023] [Accepted: 02/02/2023] [Indexed: 02/17/2023] Open
Abstract
Eleven manganese 4'-substituted-2,2':6',2″-terpyridine complexes (1a-1c and 2a-2h) with three non-oxygen-containing substituents (L1a-L1c: phenyl, naphthalen-2-yl and naphthalen-1-yl, L1a-L1c) and eight oxygen-containing substituents (L2a-L2h: 4-hydroxyl-phenyl, 3-hydroxyl-phenyl, 2-hydroxyl-phenyl, 4-methoxyl-phenyl, 4-carboxyl-phenyl, 4-(methylsulfonyl)phenyl, 4-nitrophenyl and furan-2-yl) were prepared and characterized by IR, elemental analysis or single crystal X-ray diffraction. In vitro data demonstrate that all of these show higher antiproliferative activities than cisplatin against five human carcinoma cell lines: A549, Bel-7402, Eca-109, HeLa and MCF-7. Compound 2d presents the strongest antiproliferative effect against A549 and HeLa cells, with IC50 values being 0.281 μM and 0.356 μM, respectively. The lowest IC50 values against Bel-7402 (0.523 μM) Eca-109 (0.514 μM) and MCF-7 (0.356 μM) were obtained for compounds 2h, 2g and 2c, respectively. Compound 2g with a nitro group showed the best results on the whole, with relevantly low IC50 values against all the tested tumor cells. The DNA interactions with these compounds were studied by circular dichroism spectroscopic and molecular modeling methods. Spectrophotometric results revealed that the compounds have strong affinities in binding with DNA as intercalators, and the binding induces DNA conformational transition. Molecular docking studies indicate that the binding is contributed by the π-π stacking and hydrogen bonds. The anticancer activities of the compounds are correlated with their DNA binding ability, and the modification of oxygen-containing substituents significantly enhanced the anticancer activity, which could provide a new rationale for the future design of terpyridine-based metal complexes with antitumor potential.

Abstract
Eleven copper chloride coordination compounds (1-11) with 4'-(4'-substituted-phenyl)-2,2':6',2''-terpyridine ligands bearing hydrogen (L1), cyano (L2), p-hydroxyl (L3), m-hydroxyl (L4), o-hydroxyl (L5), methoxyl (L6), iodo (L7), bromo (L8), chloro (L9), fluoro (L10) or methylsulfonyl (L11) were prepared and characterized by IR spectroscopy, elemental analysis and single crystal X-ray diffraction. Antiproliferative activities against tumor cells were investigated and DNA interactions were studied by circular dichroism spectroscopy and molecular modeling methods. In vitro data demonstrate that all the compounds exhibit higher antiproliferative activities as compared to cisplatin against five human carcinoma cell lines: A549, Bel-7402, Eca-109, HeLa and MCF-7. Compound 6 with methoxyl shows the best anti-proliferation activity. Spectrophotometric results reveal the strong affinity of the compounds for binding with DNA as intercalators and induce DNA conformational transitions. The results of molecular docking studies show that the compounds interact with DNA through π-π stacking, van der Waals forces, hydrophobic interactions and hydrogen bonds. The binding energies between compound 11 and three macromolecules, including DNA duplex, oligonucleotide and DNA-Topo I complex, are the lowest. The binding stability of compounds containing hydroxyl, methoxy and methylsulfonyl groups with biological macromolecules mainly relies on the hydrogen bonds. The ability of a compound to form hydrogen bonds can promote its binding to biological targets, thereby exhibiting high antiproliferative activity.

Abstract
The interaction between ibuprofen-Zn(II) complex and calf thymus DNA in physiological buffer (pH 7.4) was studied with the use of Hoechst 33258 and methylene blue dyes as spectral probes by multi-spectroscopic techniques, and viscosity measurements. It was found that ibuprofen-Zn(II) complex molecules could bind with DNA via groove binding mode as evidenced by: i- DNA binding constant (Kb = (1.00 ± 0.2) × 104 M-1) from Spectrophotometric studies of the interaction of ibuprofen-Zn(II) complex with DNA is comparable to groove binding drugs. ii- Absorption Spectra of Competitive interaction of ibuprofen-Zn(II) complex and Hoechst 33258 with DNA exhibited the reverse process, The results suggested that interaction of the ibuprofen-Zn(II) complex with calf thymus DNA, is similar to Hoechst 33258 interaction with calf thymus DNA (This was verified by the following fluorescence study). iii- Competitive fluorimetric studies with Hoechst 33258 have shown that ibuprofen-Zn(II) complex exhibit the ability of this complex to displace with DNA-bounded Hoechst 33258, indicating that it binds to DNA in strong competition with Hoechst 33258 for the groove binding. iv- There is no significantly change in the fluorescence intensity of the MB-DNA system upon adding the ibuprofen-Zn(II) complex, indicate that MB molecules are not released from the DNA helix after addition of the ibuprofen-Zn(II) complex and are indicative of a non-intercalative mode of binding. v- Small changes in DNA viscosity in the presence of ibuprofen-Zn(II) complex, indicating weak link to DNA, which is consistent with DNA groove binding. As well as, induced CD spectral changes, and the docking results revealed that groove mechanism is followed by ibuprofen-Zn(II) complex to bind with DNA.

Abstract
A new oxamido-bridged dicopper(II) complex with formula of [Cu2(deap)(pic)2], where H2deap and pic represent N,N'-bis[3-(diethylamino)propyl]oxamide and picrate, respectively, was synthesized and characterized by elemental analyses, molar conductance measurements, IR and electronic spectral study, and single-crystal X-ray diffraction. The crystal structure analyses revealed that the two copper(II) atoms in the dicopper(II) complex are bridged by the trans-deap(2-) ligand with the distances of 5.2116(17)Å, and the coordination environment around the copper(II) atoms can be described as a square-planar geometry. Hydrogen bonding and π-π stacking interactions link the dicopper(II) complex into a three-dimensional infinite network. The DNA/protein-binding properties of the complex are investigated by molecular docking and experimental assays. The results indicate that the dicopper(II) complex can interact with HS-DNA in the mode of intercalation and effectively quench the intrinsic fluorescence of protein BSA by 1:1 binding with the most possible binding site in the proximity of Trp134. The in vitro anticancer activities suggest that the complex is active against the selected tumor cell lines, and IC50 values for SMMC-7721 and HepG2 are lower than cisplatin. The effects of the electron density distribution of the terminal ligand and the chelate ring arrangement around copper(II) ions bridged by symmetric N,N'-bis(substituted)oxamides on DNA/BSA-binding ability and in vitro anticancer activity are preliminarily discussed.

Abstract
Three novel copper(II) complexes CuL(1)Cl2 (1) (L(1)=4'-(3-methoxyphenyl)-2,2':6'- 2″-terpyridine), CuL(2)Cl2 (2) (L(2)=4'-(4-methoxyphenyl)-2,2':6'-2″-terpyridine) and CuL(3)Cl2 (3) (L(3)=4'-(3,5-dimethoxyphenyl)-2,2':6'-2″-terpyridine) have been synthesized and characterized. Absorption spectral titration experiments, ethidium bromide displacement assays, and cyclic voltammetric experiments were carried out and the results suggested that these complexes bound to DNA through an intercalative mode. Moreover, these complexes were found to cleave pBR322 DNA efficiently in the presence of glutathione (GSH), and exhibited good anticancer activity against HeLa, Hep-G2 and BEL-7402 cell lines. Nuclear chromatin cleavage was also observed by acridine orange/ethidium bromide (AO/EB) staining assays and comet assays. These results demonstrated that these three Cu(II) complexes caused DNA damage and induced the apoptosis of HeLa cells. Mechanistic investigations revealed the participation of reactive oxygen species which can be trapped by reactive oxygen species (ROS) radical scavengers and ROS sensors.
