Abstract
TOP2 inhibitors (TOP2i) are effective drugs for breast cancer treatment. However, they can cause cardiotoxicity in some women. The most widely used TOP2i include anthracyclines (AC) Doxorubicin (DOX), Daunorubicin (DNR), Epirubicin (EPI), and the anthraquinone Mitoxantrone (MTX). It is unclear whether women would experience the same adverse effects from all drugs in this class, or if specific drugs would be preferable for certain individuals based on their cardiotoxicity risk profile. To investigate this, we studied the effects of treatment of DOX, DNR, EPI, MTX, and an unrelated monoclonal antibody Trastuzumab (TRZ) on iPSC-derived cardiomyocytes (iPSC-CMs) from six healthy females. All TOP2i induce cell death at concentrations observed in cancer patient serum, while TRZ does not. A sub-lethal dose of all TOP2i induces limited cellular stress but affects calcium handling, a function critical for cardiomyocyte contraction. TOP2i induce thousands of gene expression changes over time, giving rise to four distinct gene expression response signatures, denoted as TOP2i early-acute, early-sustained, and late response genes, and non-response genes. There is no drug- or AC-specific signature. TOP2i early response genes are enriched in chromatin regulators, which mediate AC sensitivity across breast cancer patients. However, there is increased transcriptional variability between individuals following AC treatments. To investigate potential genetic effects on response variability, we first identified a reported set of expression quantitative trait loci (eQTLs) uncovered following DOX treatment in iPSC-CMs. Indeed, DOX response eQTLs are enriched in genes that respond to all TOP2i. Next, we identified 38 genes in loci associated with AC toxicity by GWAS or TWAS. Two thirds of the genes that respond to at least one TOP2i, respond to all ACs with the same direction of effect. Our data demonstrate that TOP2i induce thousands of shared gene expression changes in cardiomyocytes, including genes near SNPs associated with inter-individual variation in response to DOX treatment and AC-induced cardiotoxicity.

Abstract
A new rapid and highly sensitive stability-indicating spectrofluorimetric method was developed for the determination of two stereoisomers anticancer drugs, doxorubicin (DOX) and epirubicin (EPI) in pure form and in pharmaceutical preparations. The fluorescence spectral behavior of DOX and EPI in a sodium dodecyl sulfate (SDS) micellar system was investigated. It was found that the fluorescence intensity of DOX and EPI in an aqueous solution of phosphate buffer pH4.0 and in the presence of SDS was greatly (about two fold) enhanced and the mechanism of fluorescence enhancement effect of SDS on DOX was also investigated. The fluorescence intensity of DOX or EPI was measured at 553nm after excitation at 497nm. The plots of fluorescence intensity versus concentration were rectilinear over a range of 0.03-2μg/mL for both DOX and EPI with good correlation coefficient (r>0.999). High sensitivity to DOX and EPI was attained using the proposed method with limits of detection of 10 and 9ng/mL and limits of quantitation of 29 and 28ng/mL, for DOX and EPI, respectively. The method was successfully applied for the determination of DOX and EPI in biological fluids and in their commercial pharmaceutical preparations and the results were concordant with those obtained using a previously reported method. The application of the proposed method was extended to stability studies of DOX following different forced degradation conditions (acidic, alkaline, oxidative and photolytic) according to ICH guidelines. Moreover, the kinetics of the alkaline and oxidative degradation of DOX was investigated and the apparent first-order rate constants and half-life times were calculated.

Abstract
Anthracyclines are amongst the most widely used drugs in oncology, being part of the treatment regimen in most patients receiving systemic chemotherapy. This review provides a comprehensive summary of the sample preparation techniques and chromatographic methods that have been developed during the last two decades for the analysis of the 4 most administered anthracyclines, doxorubicin, epirubicin, daunorubicin and idarubicin in plasma, serum, saliva or urine, within the context of clinical and pharmacokinetic studies or for assessing occupational exposure. Following deproteinization, liquid-liquid extraction, solid phase extraction or a combination of these techniques, the vast majority of methods utilizes reversed-phase C18 stationary phases for liquid chromatographic separation, followed by fluorescence detection, or, more recently, tandem mass spectrometric detection. Some pros and cons of the different techniques are addressed, in addition to potential pitfalls that may be encountered in the analysis of this class of compounds.

Abstract
Drug Eluting Microsphere-Transarterial Chemoembolization (DEM-TACE) is a new delivery system to administrate drugs in a controlled manner useful for application in the chemoembolization of colorectal cancer metastases to the liver. DEM-TACE is focused to obtain higher concentrations of the drug to the tumor with lower systemic concentrations than traditional cancer chemotherapy. Therefore a specific, precise and sensitive LC-ESI-MS/MS assay procedure was properly designed to detect and quantify epirubicin at the concentrations expected from a transarterial chemoembolization with microspheres. Serum samples were kept acidic (pH approximately of 3.5) and sample preparation consisted of a solid phase extraction (SPE) procedure with HLB OASIS cartridges using a methylene chloride/2-propanol/methanol mixture solution to recover epirubicin. The analyses consisted of reversed-phase high-performance liquid chromatography (rp-HPLC) coupled with tandem mass spectrometry (MS/MS). Accuracy, precision and matrix effect of this procedure were carried out by analyzing four quality control samples (QCs) on five separate days. The validation parameters were assessed by recovery studies of spiked serum samples. Recoveries were found to vary between 92 and 98% at the QC levels (5, 40, 80 and 150 microg/L) with relative standard deviation (RSD) always less than 3.7%. The limit of detection (LOD) was set at 1 microg/L. The developed procedure has been also applied to investigate the different capability of two types of commercially available microspheres to release epirubicin into the human circulatory system.

Abstract
The usefulness of epirubicin in the treatment of adult and childhood malignant diseases is related in part to the potential reduction in cardiac toxicity compared with that of other anthracyclines given at equivalent doses. An important pathway for epirubicin detoxification is UGT2B7-dependent glucuronidation. This study was implemented to provide a preclinical evaluation of the metabolism of epirubicin with respect to age-related changes in epirubicin glucuronidation in pediatric liver microsomes. Rates of epirubicin glucuronidation and levels of UGT2B7 were determined for liver microsomes from four pediatric age categories (n = 32) and one adult age category (n = 8). Both sets of data showed an increase in UGT2B7 activity and content with increasing age. Epirubicin glucuronidation activity in the adult group was statistically higher compared with all pediatric age groups (p < or = 0.01). UGT2B7 expression also was statistically higher in adults compared with children below 11 years of age, with evidence of significant differences in protein levels among the pediatric age categories. A positive correlation (r = 0.68) between UGT2B7 levels and postnatal age was observed, suggesting a progressive increase in UGT2B7 protein expression with increasing age. However, allometric scaling using the (3/4) power rule suggested no difference in activity between any of the pediatric age categories and the adult, although only a single neonatal sample was included in the analysis. In summary, these in vitro data show differences in epirubicin glucuronidation and UGT2B7 content within pediatric age groups and support the use of epirubicin in pediatric patients at least 6 months of age.

Abstract
Hydrophilic interaction chromatography has been applied for the separation of epirubicin and its analogues using high-purity silica column with aqueous-organic mobile phase. Parameters affecting the chromatographic behavior of the solutes such as organic modifier, buffer pH, ionic strength and sample size, have been investigated. Of utmost importance for successful separation of these analogues is the choice of organic modifier, since it impacts both the solvent selectivity and the ionization of silica silanols as well as buffer solution, and consequently the retention behavior of solutes. Acetonitrile was shown to offer superior separation of these analogues to methanol, isopropanol or tetrahydrofuran. Results of the effects of organic modifier, buffer pH and ion strength indicate that the retention mechanism is a mixed-mode of adsorption and ion exchange. In addition, an irreversible adsorption of these compounds was found on silica in the weakly acidic or neutral mobile phases, and the effect of various factors on irreversible adsorption was also preliminarily discussed. More significantly, these basic compounds have exhibited peaks with a slanted front and a sharp tail, a typical overloading peak profile belonging to the behavior of competitive anti-Langmuir isotherm by increasing the sample size at the experimental conditions.

Abstract
The interaction of an antitumoural drug, Epirubicin HCl, with anionic (sodiumdodecylsulfate; SDS), cationic (cetyltrimethylammonium bromide; CTAB), and nonionic (t-octylphenoxypolyethoxyethanol; TX-100, polyoxyethylenesorbitanmonolaurate; Tween 20) surfactants has been studied by absorption spectra as a function of surfactant concentration ranging from the premicellar to postmicellar region. At the concentrations below the critical micelle concentration (CMC), the equilibrium complex formation constant between Epirubicin cations and SDS anions has been determined by Job's method. Above the CMC, binding constant (K(b)) of Epirubicin to various types of micelles has been calculated by means of the Benesi-Hildebrand Equation. The nonionic surfactant micelles showed stronger interaction than the ionic SDS micelles, and the binding tendency of Epirubicin followed the order: Tween 20 > TX-100 > SDS. Binding of Epirubicin also has been studied in the presence of NaCl and glucose because it is administered to patients intravenously in 0.9% NaCl or 5% glucose solution. The additives have been observed to affect the CMC of the surfactants and the Epirubicin-micelle binding constant appreciably. The presence of NaCl and glucose lowered the CMC of all the surfactants studied. The binding constant of Epirubicin decreased in the presence of NaCl but increased in the presence of glucose. The equilibrium complex formation constant between Epirubicin and SDS decreased in the presence of NaCl compared with purely aqueous media.

Abstract
Health-care workers handling antineoplastic agents may be exposed to extremely low doses of these drugs. Very sensitive and specific analytical methods are therefore needed for biological monitoring. The aim of this study was to develop and validate a method for trace level determination of doxorubicin, epirubicin, daunorubicin and idarubicin in human urine, using epi-daunorubicin as an internal standard. Solid-phase extraction (SPE) was used for sample preparation. Urine samples were loaded onto Bond Elut C18 cartridges. The analytes were eluted in methylene chloride/2-propanol (1:1, v/v) and then evaporated to dryness. The residue was reconstituted with the mobile phase prior to high-performance liquid chromatography/tandem mass spectrometry (HPLC/MS/MS) analysis. Quantitation of each analyte was performed using the multiple reaction monitoring (MRM) method. The urine assay was linear over the range 0.1-2.0 microg/L, with a lower limit of quantification (LLOQ) of 0.10 microg/L for doxorubicin and epirubicin, and 0.03 microg/L for daunorubicin and idarubicin. The respective limits of detection (LODs) were 0.04 and 0.01 microg/L. The precision and accuracy of the assay were determined on three different days. The within-series precision was found to be always less than 13.9% for all the analytes. The overall precision expressed as relative standard deviation (RSD) was always less than 10.6%. The recovery of anthracyclines was assessed at two concentrations of the range tested (0.1 and 2.0 microg/L) and it ranged from 87.7% (daunorubicin) to 102.0% (doxorubicin) and from 79.1% (daunorubicin) to 90.7% (idarubicin) for the lower and the higher level, respectively, with a RSD always less than 9.1%. The uncertainty of the present assay was also evaluated and the combined uncertainty was always less than 20% over all the days of the validation study. This is the first method that makes use of LC/MS/MS for the biological monitoring of occupational exposure to anthracyclines.

Abstract
Various methods for separating eleven different types of topoisomerase II (TOPO-2) inhibitors, including epipodophyllotoxins, anthracyclines, anthracenediones, anthrapyrazoles, anthracenebishydrazones, indole derivatives, aminoacridines, benzisoquinolinediones, isoflavones, bisdioxopiperazines and thiobarbituric acids, are summarized. Proper sample preparation and storage is critical to the successful analysis of some TOPO-2 inhibitors due to difficulties associated with adsorption, instability and complex biological components. Solid-phase and liquid-liquid extractions are widely used to separate TOPO-2 inhibitors from biological samples, although simple deproteinization followed by direct analysis of the supernatant is preferable to extraction based on its speed and simplicity. High-performance liquid chromatography (HPLC) is the favored method for the bioanalysis of TOPO-2 inhibitors. UV or diode array detection is generally employed for early pharmacokinetic studies, while fluorescence or electrochemical detection is used more frequently for analytes with fluorescent or oxidative-reductive properties. For analyses requiring highly sensitive and/or specific detection, electrospray mass spectrometry (ESI-MS or ESI-MS-MS) provides a suitable alternative. A comprehensive compilation of the HPLC techniques currently used to separate TOPO-2 inhibitors will aid the future development of analytical methods for new TOPO-2 inhibitors.

Abstract
Anthracyclines are among the most widely used anticancer agents. Notwithstanding the large efforts to develop new drugs with a better pharmaceutical profile, daunorubicin, doxorubicin, epirubicin and idarubicin are still the most used in clinical practice. Many efforts are now ongoing to reduce the side effects by using pharmaceutical formulations able to release the drug in the most appropriate way and monitoring the quantity of anthracyclines and their metabolites in the body fluids or tissues frequently and in every patient to maintain the drug concentration within the expected range. This review describes the most recent developments in the separation and quantitation of the above clinically useful drugs, together with their principal metabolites. Some less widely used derivatives will also be considered.

Abstract
A sensitive and very specific method, using liquid chromatography-electrospray mass spectrometry (LC-ES-MS), was developed for the determination of epirubicin, doxorubicin, daunorubicin, idarubicin and the respective active metabolites of the last three, namely doxorubicinol, daunorubicinol and idarubicinol in human serum, using aclarubicin as internal standard. Once thawed, 0.5-ml serum samples underwent an automated solid-phase extraction, using C18 Bond Elut cartridges (Varian) and a Zymark Rapid-Trace robot. After elution of the compounds with chloroform-2-propanol (4:1, v/v) and evaporation, the residue was reconstituted with a mixture of 5 mM ammonium formate buffer (pH 4.5)-acetonitrile (60:40, v/v). The chromatographic separation was performed using a Symmetry C18, 3.5 microm (150 x 1 mm I.D.) reversed-phase column, and a mixture of 5 mM ammonium formate buffer (pH 3)-acetonitrile (70:30, v/v) as mobile phase, delivered at 50 microl/min. The compounds were detected in the selected ion monitoring mode using, as quantitation ions, m/z 291 for idarubicin and idarubicinol, m/z 321 for daunorubicin and daunorubicinol, m/z 361 for epirubicin and doxorubicin, m/z 363 for doxorubicinol and m/z 812 for aclarubicin (I.S.). Extraction recovery was between 71 and 105% depending on compounds and concentration. The limit of detection was 0.5 ng/ml for daunorubicin and idarubicinol, 1 ng/ml for doxorubicin, epirubicin and idarubicin, 2 ng/ml for daunorubicinol and 2.5 ng/ml for doxorubicinol. The limit of quantitation (LOQ) was 2.5 ng/ml for doxorubicin, epirubicin and daunorubicinol, and 5 ng/ml for daunorubicin, idarubicin, doxorubicinol and idarubicinol. Linearity was verified from these LOQs up to 2000 ng/ml for the parent drugs (r > or = 0.992) and 200 ng/ml for the active metabolites (r > or = 0.985). Above LOQ, the within-day and between-day precision relative standard deviation values were all less than 15%. This assay was applied successfully to the analysis of human serum samples collected in patients administered doxorubicin or daunorubicin intravenously. This method is rapid, reliable, allows an easy sample preparation owing to the automated extraction and a high selectivity owing to MS detection.

Abstract
A single high-performance liquid chromatography (HPLC) method, suitable for the analysis of daunorubicin, idarubicin, doxorubicin, epirubicin, and their 13-dihydro metabolites is validated in the present study. Preparation of plasma samples was performed by a first extraction of analytes with a chloroform/1-heptanol mixture (9:1) and reextraction with ortophosphoric acid 0.1 M. The chromatographic analysis was carried out by reversed-phase isocratic elution of anthracyclines with a Supelcosil LC-CN 5 mm column (25 cm x 4.6 mm internal diameter; Supelco) and detection was accomplished by spectrofluorimetry at excitation and emission wavelengths of 480 and 560 nm, respectively. All anthracyclines eluted within 15 minutes of injection and the method appeared to be specific, because the chromatographic assay did not show interferences at the retention time of analytes. The linearity, evaluated over a concentration range of 0.4-10,000 ng/mL, gave regression coefficients better than 0.999, with recoveries of doxorubicin-doxorubicinol and epirubicin-epirubicinol of 67%-109% and 61%-109% respectively, and 93%-109% for the other compounds. The limits of detection and quantification were 0.4 ng/mL in a 50-mL sample (40 pg/injection) for all anthracyclines tested. The method proved to be precise and accurate, as the within-day and between-day coefficients of variation were less than 10% and the accuracy of the assay was in the range of 91%-107%. Overall results indicate that it is feasible to analyze all the anthracyclines used in clinical practice and their major metabolites with a single optimized method, thereby simplifying their monitoring in chemotherapeutic regimens of cancer patients.

Abstract
A high-performance liquid chromatographic method with electrochemical detection has been developed for the simultaneous determination of epirubicin, 13-S-dihydroepirubicin, doxorubicin and 13-S-dihydrodoxorubicin in human plasma. An aliquot of 200 microl plasma, spiked with internal standard, was extracted by solid-phase extraction using polymeric adsorbent columns. Chromatography was performed using a C18 reversed-phase column with a mobile phase consisting of water-acetonitrile (71:29, v/v) containing 0.05 M Na2HPO4 and 0.05% v/v triethylamine adjusted to pH 4.6 with citric acid. Linearity of the method was obtained in the concentration range of 1-500 ng/ml for all the analytes. Analytical recoveries of the analytes ranged from 89 to 93%. The assay can be used for the simultaneous determination of the four analytes, or for epirubicin and its metabolite or doxorubicin and its metabolite, using the other parent drug as an internal standard. The method was applied to analyze human plasma samples from patients treated with epirubicin using doxorubicin as an internal standard.
