Abstract
Both the design of molecules that will interact specifically with DNA and the determination of the mechanism of action of this drug on DNA are important as they allow the control of gene expression. In particular, rapid and precise analysis of this type of interaction is a vital element for pharmaceutical studies. In the present study, a novel reduced graphene oxide/ palladium nanoparticles/ poly(2-amino-4-chlorophenol) (rGO/Pd@PACP) nanocomposite was synthesized by chemical process to modify pencil graphite electrode (PGE) surface. Here, the performance of the newly developed nanomaterial-based biosensor for drug-DNA interaction analysis has been demonstrated. For this purpose, it was determined whether this system, which was developed by selecting a drug molecule (Mitomycin C; MC) known to interact with DNA and a drug molecule (Acyclovir; ACY) that does not interact with DNA, performs a reliable/accurate analysis. Here, ACY was used as a negative control. Compared to bare PGE, the rGO/Pd@PACP nanomaterial modified sensor exhibited 17 times higher sensitivity performance in terms of guanine oxidation signal measured by differential pulse voltammetry (DPV). Moreover, the developed nanobiosensor system provided a highly specific determination between the anticancer drug MC and ACY by discrimination the interactions of these drugs with double-stranded DNA (dsDNA). ACY was also preferred in studies for the optimization of the new nanobiosensor developed. ACY was detected in a concentration as low as 0.0513 μM (51.3 nM) (LOD), and limit of quantification (LOQ) was 0.1711 μM with a linear range from 0.1 to 0.5 μM.

Abstract
Cancer is most frequently treated with antineoplastic agents (ANAs) that are hazardous to patients undergoing chemotherapy and the healthcare workers who handle ANAs in the course of their duties. All aspects related to hazardous oncological drugs illustrate that the monitoring of ANAs is essential to minimize the risks associated with these drugs. Among all analytical techniques used to test ANAs, electrochemistry holds an important position. This review, for the first time, comprehensively describes the progress done in electrochemistry of ANAs by means of a variety of bare or modified (bio)sensors over the last four decades (in the period of 1982-2021). Attention is paid not only to the development of electrochemical sensing protocols of ANAs in various biological, environmental, and pharmaceutical matrices but also to achievements of electrochemical techniques in the examination of the interactions of ANAs with deoxyribonucleic acid (DNA), carcinogenic cells, biomimetic membranes, peptides, and enzymes. Other aspects, including the enantiopurity studies, differentiation between single-stranded and double-stranded DNA without using any label or tag, studies on ANAs degradation, and their pharmacokinetics, by means of electrochemical techniques are also commented. Finally, concluding remarks that underline the existence of a significant niche for the basic electrochemical research that should be filled in the future are presented.

Abstract
Small molecules that bind genomic DNA have proven that they can be effective anticancer, antibiotic and antiviral therapeutic agents that affect the well-being of millions of people worldwide. Drug-DNA interaction affects DNA replication and division; causes strand breaks, and mutations. Therefore, the investigation of drug-DNA interaction is needed to understand the mechanism of drug action as well as in designing DNA-targeted drugs. On the other hand, the interaction between DNA and drugs can cause chemical and conformational modifications and, thus, variation of the electrochemical properties of nucleobases. For this purpose, electrochemical methods/biosensors can be used toward detection of drug-DNA interactions. The present paper reviews the drug-DNA interactions, their types and applications of electrochemical techniques used to study interactions between DNA and drugs or small ligand molecules that are potentially of pharmaceutical interest. The results are used to determine drug binding sites and sequence preference, as well as conformational changes due to drug-DNA interactions. Also, the intention of this review is to give an overview of the present state of the drug-DNA interaction cognition. The applications of electrochemical techniques for investigation of drug-DNA interaction were reviewed and we have discussed the type of qualitative or quantitative information that can be obtained from the use of each technique.

Abstract
Temozolomide (TMZ) is an anticancer drug used for the treatment of adult brain tumour and skin cancer. The biomolecular interaction between TMZ and DNA was investigated for the first time in this study using disposable pencil graphite electrodes (PGEs) in combination with electrochemical techniques. The surface confined interactions between TMZ and different type of nucleic acids were performed. Before/after surface confined interaction process, the oxidation signals of TMZ, guanine and adenine were measured using differential pulse voltammetry (DPV) and PGE and accordingly, the changes at the oxidation signals were evaluated. The detection limit (DL) was also estimated based on the oxidation signal of TMZ. The interaction of TMZ with single stranded poly [A], poly [G], or double stranded poly [A]-poly[T] and poly [G]-poly[C] was also explored. Moreover, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques were utilized for detection the interaction between TMZ and DNA. The features of this single-use electrochemical sensor was discussed in comparison to other reports that were developed for TMZ detection.

Abstract
The interaction of Efavirenz (EFV) with fish sperm dsDNA immobilized onto pencil graphite electrode (PGE) has been studied by using differential pulse voltammetric technique using an electrochemical DNA biosensor. The guanine signal was lower with (double stranded-DNA) dsDNA-treated PGE than the untreated electrode after the interaction with EFV occurred. The changes in the experimental parameters such as the accumulation time and the concentration of EFV were also studied. All necessary parameters such as sensitivity, selectivity, accuracy and precision were calculated. In addition, the detection and determination limits, reproducibility and applicability of the analysis to pharmaceutical dosage forms were also investigated. These results showed that this DNA biosensor could be used for the sensitive, rapid simple and cost effective detection and determination of EFV-dsDNA interaction. The linearity was between 2 and 24 ppm of EFV concentration on guanine signal decreasing curve. EFV showed an irreversible oxidation behavior at all investigated pH values. This oxidation step was adsorption controlled on PGE. Hence, differential pulse adsorptive stripping (AdsDPV) voltammetric method was developed for the determination of EFV. Accumulation time and potential were optimized. Under these conditions, the current showed a linear dependence with concentration in the range between 0.018 and 2.56 ppm. Both determination methods were fully validated and applied for the analysis of EFV pharmaceutical dosage form.

BIOCHIMICA ET BIOPHYSICA ACTA-PROTEINS AND PROTEOMICS 2008; 1784:666-71. [PMID: 18284927 DOI: 10.1016/j.bbapap.2008.01.012] [Citation(s) in RCA: 54] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2007] [Revised: 12/27/2007] [Accepted: 01/15/2008] [Indexed: 11/25/2022]
Abstract
Polycyclic aromatic hydrocarbons are among the most threatening pollutants widely present in the environment. Simple and economic methods of continuous monitoring of these compounds in real time are not yet available, although becoming increasingly needed. Odorant-binding proteins (OBPs) present unique characteristics of thermal and chemical stability for building robust, reliable, and inexpensive biosensors for such molecules. To investigate this possibility, we have engineered the pig OBP, whose three-dimensional structure has been resolved, introducing a tryptophan residue in the core of the binding pocket, as a fluorescence reporter for the presence of bound ligands. Binding affinities of several polyaromatic hydrocarbons to mutagenically modified OBPs were measured in competitive binding assays. Moreover, the presence of aromatic ligands was also successfully monitored in the modified OBPs by recording the quenching of intrinsic fluorescence of the protein. These data indicate that OBPs bind several aromatic polycyclic compounds with good affinities, that the specificity of these proteins can be easily modified by changing specific amino acid residues and that the introduction of a tryptophan residue in the binding site allows monitoring of aromatic ligands using direct fluorescence measurements.

Abstract
In this work the interaction of DNA and the flavonoid-transition metal complex (Cu(II)-naringin complex) is characterized. The interaction was evaluated by using electrochemical ssDNA- and dsDNA-based biosensors and the results were supported by UV, CD and (1)H NMR data. In the electrochemical method, changes in the oxidation peak of the guanine and adenine bases obtained by square wave voltammetry (SWV) showed evidence of the interaction. The variations of the spectroscopic characteristics of DNA and Cu(II)-naringin complex in aqueous medium demonstrated that the predominant interaction mode may be by intercalation. Cu(II)-naringin complex interacts to dsDNA probably via N(7) of guanine site.

Abstract
A novel drug-delivery system was developed by loading the anticancer drug, mitomycin C (MC) into an oil/water system with the aim of investigation by electrochemical sensing the interaction between the drug and DNA in microemulsion phase. The physical and physicochemical properties (droplet size, pH, viscosity, conductivity and refractive index) of this microemulsion were examined. The electrochemical detection of the interaction between MC and double-stranded DNA (dsDNA) in microemulsion phase was performed by using differential pulse voltammetry (DPV) in combination with a disposable sensor, pencil graphite electrode (PGE). The magnitude of guanine oxidation signal was monitored before and after interaction between MC and dsDNA. The effect of different experimental parameters, such as MC concentration, MC interaction time with dsDNA, and dsDNA concentration were also studied to find the optimum analytical performance based on electrochemical detection of this interaction in microemulsion phase.

Synthesis and pharmacochemical study of new Cu(II) complexes with thiophen-2-yl saturated and alpha,beta-unsaturated substituted carboxylic acids. J Inorg Biochem 2007; 101:623-34.

Abstract
Copper complexes with thiophen-2-yl saturated and alpha,beta-unsaturated carboxylic acids as ligands were prepared, characterized and pharmacochemically studied. The available evidence supports a dimeric structure for the complexes of the general formula [Cu2(L)4(MeOH)2] where L are the anions of thiophene 2-carboxylic acid (HL1), 2-(thiophen-2-yl)-acetic acid (HL2), 3-thiophen-2-yl-acrylic acid (HL3), 2-phenyl-3-thiophen-2-yl-acrylic acid (HL4) respectively. The crystal structure of [Cu2(L1)4(MeOH)2] (2) was determined while preliminary X-ray analysis of the copper complex with L4 isolated from MeOH/DMSO solution proved to contain three crystallographically independent dimers of the formula [Cu2(L4)4(MeOH)(dmso)][Cu2(L4)4(MeOH)2][Cu2(L4)4(dmso)2].8MeOH (9). Since lipophilicity is a significant physicochemical property determining distribution, bioavailability, metabolic activity and elimination, we tried to measure experimentally their lipophilicity from RPTLC method. The copper complexes and the ligands (thiophen-2-yl saturated and alpha,beta-unsaturated carboxylic acids) were tested in vitro on: (a) soybean lipoxygenase inhibition, (b) interaction with 1,1-diphenyl-2-picryl-hydrazyl (DPPH) stable free radical, (c) the HO* mediated oxidation of DMSO, (d) inhibition of lipid peroxidation, (e) scavenging of superoxide anion radicals and in vivo for the inhibition of carrageenin-induced rat paw edema. The compounds have shown important antioxidant activity, significant anti-inflammatory activity and potent inhibition of soybean lipoxygenase as a result of their physichochemical features. Complex [Cu2(L1)4(MeOH)2] (2) presents the higher in vivo activity (77.4%) followed by complex [Cu2(L2)4(MeOH)2] (4) (51%). Both complexes are more potent anti-inflammatory agents compared to their respective ligands. Moreover we have performed in vitro studies upon their effect on dsDNA, using adsorptive transfer stripping voltammetry and a dsDNA modified carbon paste electrode. Our conclusions were mainly based upon the effect of the studied compounds on the oxidation signal of guanine and adenine. From the given data it seems that complexes show similarities in their behaviour.

Abstract
In the present work, electrochemical DNA biosensors are proposed as a screening device for the rapid bio-analysis of environmental pollution and DNA-drug interaction studies. The binding of small molecules to DNA immobilised on disposable screen-printed electrodes has been measured through the variation of the electrochemical signal of guanine by square wave voltammetric scans. These kinds of biosensors were used to evaluate the soil contamination level in an Italian polluted area and the results were compared with several methods for the DNA damage detection, as Comet genotoxicity effects, aberrant anatelophases and micronucleated cells frequency on plant roots, and with fixed wavelength fluorescence (FF) by using 2-aminoanthracene as standard compound. The results showed the ability of the biosensors to distinguish in 11 min low, medium and high contaminated soils with good correlation with well established techniques as well as FF, Comet and genotoxicity tests. The same kind of biosensors was also used to evaluate the interaction of DNA with some anti-proliferative metallo drugs, and the electrochemical responses reflected the kind of interaction. The reproducibility of the electrochemical measurements of DNA guanine peak was estimated as less than 10% of relative standard deviation (R.S.D.%).

Abstract
The interaction of cis-diamminedichloroplatinum(II) (cis-DDP) and the potential novel chemotherapeutic agent, cis-bis(3-aminoflavone)dichloroplatinum(II) (cis-BAFDP) was studied electrochemically with calf thymus double-stranded DNA (dsDNA) by using differential pulse voltammetry (DPV) with disposable pencil graphite electrode (PGE) at the surface. These studies were prompted by beneficial biological properties of cis-BAFDP in comparison with cis-DDP, which were proven in vitro both in human normal and cancer cells and in vivo. The changes in the experimental parameters such as the concentration of cis-DDP and cis-BAFDP were studied by using DPV; in addition, the reproducibility of this genosensor and the detection limit for each compound were determined. After the interaction of cis-DDP with dsDNA, the DPV signal of guanine and adenine was found to be decreasing. In comparison with cis-DDP, a dramatic decrease at adenine signal was also obtained after the interaction of cis-BAFDP and dsDNA. Similar results were also found in solution phase after the latter compound interacts with poly[A]. The features of the proposed electrochemical method for the detection of cis-BAFDP with DNA in comparison with cis-DDP are discussed and compared with those methods previously reported for the other type of DNA-targeted agents in the literature.

Abstract
The change in electrochemical behavior of tumor cells induced by antitumor drugs was detected by using a multiwall carbon nanotubes (MWNTs)-modified glass carbon electrode (GCE). Based on the changes observed, a simple, in vitro, electrochemical antitumor drug sensitivity test was developed. MWNTs promoted electron transfer between the electroactive centers of cells and the electrode. Leukemia K562 cells exhibited a well-defined anodic peak of guanine at +0.823 V at 50 mV s(-1). HPLC assay with ultraviolet detection was used to elucidate the reactant responsible for the electrochemical response of the tumor cells. The guanine content within the cytoplasm of each K562 cell was detected to be 920 amol. For the drug sensitivity tests, 5-fluorouracil (5-FU) and several clinical antitumor drugs, such as vincristine, adriamycin, and mitomycin C, were added to cell culture medium. As a result, the electrochemical responses of the K562 cells decreased significantly. The cytotoxicity curves and results obtained corresponded well with the results of MTT assays. In comparison to conventional methods, this electrochemical test is highly sensitive, accurate, inexpensive, and simple. The method proposed could be developed as a convenient means to study the sensitivity of tumor cells to antitumor drugs.

Abstract
Rifampicin (RIF) is an antibiotic widely used against tuberculosis and a DNA intercalator. The interaction of RIF with double-stranded (ds) and single-stranded (ss) calf thymus DNA was studied in solution as well as at the electrode surface by means of transfer voltammetry using differential pulse as stripping mode with carbon paste electrode (CPE) at 0.2M acetate buffer at pH 5.0 and at 0.2M phosphate buffer pH 7.4. Differentiations in the above-mentioned interaction at different pH values are presented and compared in order to optimize the detection of Rifampicin (RIF).
