Part VI: Synthesis, structures, in vitro DNA binding, antimicrobial and anticancer properties of first row transition metal complexes with 5-chloro-quinolin-8-ol. J Inorg Biochem 2015; 154:67-77. [PMID: 26600190 DOI: 10.1016/j.jinorgbio.2015.10.015] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Revised: 10/12/2015] [Accepted: 10/28/2015] [Indexed: 01/19/2023]
Abstract
A series of new 3d metal complexes with 5-chloro-quinolin-8-ol (ClQ), [Mn(ClQ)2] (1), [Fe(ClQ)3] (2), [Co(ClQ)2(H2O)2] (3), [Ni(ClQ)2(H2O)2] (4), [Cu(ClQ)2] (5), [Zn(ClQ)2(H2O)2] (6), [Mn(ClQ)3]·DMF (7) and [Co(ClQ)3]·DMF·(EtOH)0.35 (8) (DMF=N,N-dimethylformamide), has been synthesized and characterized by elemental analysis, IR spectroscopy and TG-DTA thermal analysis. X-ray structure analysis of 7 and 8 revealed that these molecular complexes contain three chelate ClQ molecules coordinated to the central atoms in a deformed octahedral geometry and free space between the complex units is filled by solvated DMF and ethanol molecules. Antimicrobial activity of 1-6 was tested by determining the minimum inhibitory concentration and minimum microbicidal concentration against 12 strains of bacteria and 5 strains of fungi. The intensity of antimicrobial action varies depending on the group of microorganism and can be sorted: 1>ClQ>6>3/4>2>5. Complexes 1-6 exhibit high cytotoxic activity against MDA-MB, HCT-116 and A549 cancer cell lines. Among them, complex 2 is significantly more cytotoxic against MDA-MB cells than cisplatin at all tested concentrations and is not cytotoxic against control mesenchymal stem cells indicating that this complex seems to be a good candidate for future pharmacological evaluation. Interaction of 1-6 with DNA was investigated using UV-VIS spectroscopy, fluorescence spectroscopy and agarose gel electrophoresis. The binding studies indicate that 1-6 can interact with CT-DNA through intercalation; complex 2 has the highest binding affinity. Moreover, complexes 1-6 inhibit the catalytic activity of topoisomerase I.

Redox cycling of endogenous copper by ferulic acid leads to cellular DNA breakage and consequent cell death: A putative cancer chemotherapy mechanism. Toxicol Appl Pharmacol 2015; 289:251-61. [PMID: 26415834 DOI: 10.1016/j.taap.2015.09.018] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2015] [Revised: 09/15/2015] [Accepted: 09/24/2015] [Indexed: 12/12/2022]
Abstract
Ferulic acid (FA) is a plant polyphenol showing diverse therapeutic effects against cancer, diabetes, cardiovascular and neurodegenerative diseases. FA is a known antioxidant at lower concentrations, however at higher concentrations or in the presence of metal ions such as copper, it may act as a pro-oxidant. It has been reported that copper levels are significantly raised in different malignancies. Cancer cells are under increased oxidative stress as compared to normal cells. Certain therapeutic substances like polyphenols can further increase this oxidative stress and kill cancer cells without affecting the proliferation of normal cells. Through various in vitro experiments we have shown that the pro-oxidant properties of FA are enhanced in the presence of copper. Comet assay demonstrated the ability of FA to cause oxidative DNA breakage in human peripheral lymphocytes which was ameliorated by specific copper-chelating agent such as neocuproine and scavengers of ROS. This suggested the mobilization of endogenous copper in ROS generation and consequent DNA damage. These results were further validated through cytotoxicity experiments involving different cell lines. Thus, we conclude that such a pro-oxidant mechanism involving endogenous copper better explains the anticancer activities of FA. This would be an alternate non-enzymatic, and copper-mediated pathway for the cytotoxic activities of FA where it can selectively target cancer cells with elevated levels of copper and ROS.

PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2015; 151:605-615. [PMID: 26163783 DOI: 10.1016/j.saa.2015.07.010] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2015] [Revised: 06/30/2015] [Accepted: 07/01/2015] [Indexed: 06/04/2023]
Abstract
The present study embodies the detail DNA binding interaction of a potential bioactive quinoline appended chalcone derivative (E)-3-(anthracen-10-yl)-1-(6,8-dibromo-2-methylquinolin-3-yl)prop-2-en-1-one (ADMQ) with calf thymus DNA (ctDNA) and its consequences by UV-Vis absorption, steady state fluorescence spectroscopy, fluorescence anisotropy, circular dichromism, helix melting, agarose gel electrophoresis, molecular docking, Induced Fit Docking (IFD) and molecular dynamics (MD) simulation. The UV-Vis absorption and fluorescence study reveal that the molecule undergoes considerable interaction with the nucleic acid. The control KI quenching experiment shows the lesser accessibility of ADMQ molecule to the ionic quencher (I(-)) in presence of ctDNA as compared to the bulk aqueous phase. Insignificant change in helix melting temperature as well as in circular dichromism (CD) spectra points toward non-covalent groove binding interaction. The moderate rotational confinement of this chalcone derivative (anisotropy=0.106) trapped in the nucleic acid environment, the comparative displacement assay with well-known minor groove binder Hoechst 33258 and intercalator Ethidium Bromide establishes the minor groove binding interactions of the probe molecule. Molecular docking, IFD and MD simulation reveal that the DNA undergoes prominent morphological changes in terms of helix unwinding and bending to accommodate ADMQ in a crescent shape at an angle of 110° in a sequence specific manner. During interaction, ADMQ rigidifies and bends the sugar phosphate backbone of the nucleic acid and thereby shortens its overall length by 3.02Å. Agarose gel electrophoresis experiment with plasmid pBR 322 reveals that the groove binded ADMQ result in a concentration dependent cleavage of plasmid DNA into its supercoiled and nicked circular form. The consolidated spectroscopic research described herein provides quantitative insight into the interaction of a heterocyclic chalcone derivative with relevant target nucleic acid, which may be useful for the future research on chalcone based therapeutic agents.

Abstract
Drug-DNA interactions have been extensively studied in the recent past. Various techniques have been employed to decipher these interactions. DNA is a major target for a wide range of drugs that may specifically or non-specifically interact with DNA and affect its functions. Interaction between small molecules and DNA are of two types, covalent interactions and non-covalent interactions. Three major modes of non-covalent interactions are electrostatic interactions, groove binding and intercalative binding. This review primarily focuses on discussing various techniques used to study non-covalent interactions that occur between drugs and DNA. Additionally, we report several techniques that may be employed to analyse the binding mode of a drug with DNA. These techniques provide data that are reliable and simple to interpret.
