Abstract
Methotrexate (MTX) is an antifolate drug used for several diseases. Depending on the disease, MTX can be administered at low dose (LDMTX) in some autoimmune diseases, like rheumatoid arthritis, or at high dose (HDMTX) in some cancers, such as acute lymphoblastic leukemia. After absorption, MTX is metabolized in the liver to 7-hydroxymethotrexate and in the intestine to 2,4-diamino-N10-methylpteroic acid (DAMPA). Moreover, inside red blood cells, MTX is converted to active metabolites, MTX polyglutamates (MTXPGs), contributing to its pharmacodynamics. Owing to its narrow therapeutic range, and inter- and intra-patient variability, either noneffectiveness and/or toxicity may occur. Because of the existence of a relationship between drug therapeutic outcome and its systemic concentration, therapeutic drug monitoring (TDM) may ensure the effectiveness and safety of MTX use. In order to monitor the optimization of patient clinical response profile, several analytical methods have been described for TDM in biological samples. These include liquid chromatography (LC) coupled with ultraviolet detection, fluorescence detection or mass spectrometry, each one presenting advantages and drawbacks. This paper reviews the most commonly used techniques for sample preparation and critically discusses the current LC methods applied for the TDM of MTX in biological samples, at LDMTX and HDMTX.

Abstract
A sensitive and simple method for the methotrexate quantification was developed using aminopterin as internal standard. Methotrexate is an anticancer agent that is widely used in a variety of human cancers including primary central nervous system lymphoma. The compound was quantified by liquid-chromatography coupled to electrospray ionization (positive ion-mode) low-energy collision dissociation-tandem mass spectrometry. Quantitative detection was by multiple reaction monitoring of the transitions of the [M+H]+ ion of MTX to its common product ion at m/z 308.4 and of aminopterin at m/z 441.2→m/z 294.0. The method demonstrated linearity over at least three orders of magnitude and had a detection limit of 1ng/ml for methotrexate. A run time of less than 8.0min for each sample made it possible to analyze a large number of human saliva samples per day. Application of this procedure was demonstrated to a saliva excretion study of methotrexate on the samples obtained after an intravenously administration of 1mg/kg/dose of methotrexate to six patients with acute lymphoblastic leukemia.

Abstract
A rapid liquid chromatography/positive ion electrospray mass spectrometric assay (LC/ESI-MS) was developed for the quantitation of methotrexate, folinic acid, folic acid and ondansetron in human serum. The assay was based on 100microL serum samples, following acetonitrile precipitation of proteins and filtration that enabled direct injection into the LC/MS system. All analytes and the internal standard, alfuzosin, were separated by using a Zorbax Eclipse XDB-C(8) analytical column (2.1mmx150.0mm i.d., particle size 3.5microm) with isocratic elution. The mobile phase was composed of a mixture of water/acetonitrile containing 0.1%, v/v formic acid (75:25, v/v), pumped at a flow rate of 0.15mLmin(-1). Quantitation of the analytes was performed with selected ion monitoring (SIM) in positive ionization mode using electrospray ionization interface. The assay was found to be linear in the concentration range of 0.01-25.00microgmL(-1) for methotrexate and 0.01-5.00microgmL(-1) for folic acid, folinic acid and ondansetron. Intermediate precision was found to be less than 4.2% over the tested concentration ranges. A run time of less than 7.0min for each sample made it possible to analyze a large number of human serum samples per day. The method can be used to quantify methotrexate, folinic acid, folic acid and ondansetron in human serum covering a variety of clinical studies and it was applied to the analysis of human serum samples obtained from children with acute lymphoblastic leukemia.

Abstract
Methotrexate (MTX) is an anticancer agent that is widely used in a variety of human cancers including primary central nervous system lymphoma (PCNSL). Important pharmacological properties that directly bear on the use of MTX in PCNSL, such as mechanisms that govern its uptake into brain tumors, are poorly defined, but are amenable to investigation in mouse models. In order to pursue such preclinical pharmacological studies, a rapid and sensitive liquid chromatography-tandem mass spectrometry (LC/MS/MS) method for the determination of MTX and its metabolite, 7-hydroxymethotrexate (7-OH MTX) in plasma and microdialysate samples from brain tumors and cerebrospinal fluid (CSF) is needed. The plasma assay was based on 10 microl samples and following a protein precipitation procedure enabled direct injection onto a LC/MS/MS system using positive electrospray ionization. A column switching technique was employed for desalting and the clean-up of microdialysate samples from brain tissues. The methods were validated for MTX and 7-OH MTX in both plasma and microdialysate samples from brain tumor and CSF, and produced lower limits of quantification (LLOQ) in plasma of 3.7 ng/ml for MTX and 7.4 ng/ml for 7-OH MTX, and in microdialysate samples of 0.7 ng/ml for both MTX and 7-OH MTX. The utility of the method was demonstrated by estimation of pharmacokinetic (PK) and brain distribution properties of MTX and 7-OH MTX in conscious mice. The method has the advantages of low sample volume, rapid clean-up, and the simultaneous measurement of MTX and 7-OH MTX in plasma and brain tissues allowing detailed PK studies to be completed in individual mice.

Abstract
A simple, sensitive and selective high performance liquid chromatographic method with UV detection for the chiral separation of racemic methotrexate (rac-Mtx) and enantiomeric purity of L-methotrexate in pharmaceutical formulations was developed and validated. The chiral separation was optimized studying both the nature of the stationary phase by using Chirobiotic T, Chiracel OJ and human serum albumin columns and the effect of the mobile phase composition. The best results in terms of enantioresolution and enantioselectivity were achieved with a polar organic mobile phase on Chirobiotic T stationary phase. Essential steps in method validation such as precision, accuracy, suitability and stability were studied according to ICH guidelines. At wavelength 303 nm, the limit of detection (S/N=3) was found to be 0.9 microg/ml for rac-Mtx. The separation of D-Mtx at 0.2% (w/w) level (as limit of quantitation) from the main drug L-Mtx was successfully obtained with 1.72 enantioresolution value. Enantiomeric purity of L-Mtx was determined in pharmaceutical formulations (tablets and injections) with inter- and intra-days relative standard deviation < or = 1.6%. Under the validated stereoselective HPLC conditions for methotrexate, folic acid was also analysed.

Abstract
Methotrexate plays a key role in adjuvant chemotherapy for treatment of osteosarcoma, but is used at a high dose because it can pass through a cell membrane only with difficulty. Therefore, if the drug delivery of methotrexate to the tumor could be enhanced, antitumor effect and survival would improve. We examined whether enhancement of the antitumor effect of electrochemotherapy was feasible by using low-dose methotrexate in mice with osteosarcoma. The tumor-bearing mice were divided into four groups: no treatment, methotrexate treatment alone, electroporation alone, and methotrexate treatment followed by electroporation. In single-treatment series, the size of the tumors in mice treated with electrochemotherapy decreased substantially 6 days after treatment, whereas continuous growth was observed in the other groups. In the series of treatments repeated three times at 6-day intervals, the original tumors in the electrochemotherapy group decreased consistently and the tumors disappeared in four of seven animals within 16 days. In the other groups, the tumors continued to grow and all host animals died within 58 days. These results show the usefulness of electroporation to enhance the effects of low-dose methotrexate and the potential benefits of electrochemotherapy for the treatment of human osteosarcoma.

Abstract
The prediction of chemotherapeutic efficacy is complicated by "protocol dependencies" in dose-effect and dose-toxicity relationships. It has been proposed that pharmacokinetic-pharmacodynamic mathematical models may allow characterization of chemotherapeutic protocol dependencies, and may facilitate the prediction of chemotherapeutic efficacy; however, few demonstrations exist in the literature. The present study examines the pharmacokinetics and toxicodynamics of methotrexate (MTX), a commonly used anticancer agent, after intraperitoneal (i.p.) administration to mice. MTX was administered via bolus or infusion (24, 72, and 168 h), at doses of 2.5-1000 mg/kg. MTX plasma and peritoneal pharmacokinetics were characterized through standard noncompartmental and compartmental techniques. Body weight loss was used as a measure of MTX-induced toxicity. We found that MTX pharmacokinetics were independent of dose (over a range of 3-600 mg/kg) and independent of dosing mode (i.e., i.p. bolus vs. i.p. infusion). However, MTX-induced toxicity was shown to be highly dependent on the dosing protocol used. For example, the maximally tolerated dose (i.e., the dose related to a mean body weight loss of 10%) was 200-fold greater after bolus administration relative to that observed for 72-h infusion (760 mg/kg vs. 3.8 mg/kg). This profound protocol dependence in the relationship between MTX-induced toxicity and MTX exposure was characterized through the use of a time-dissociated pharmacokinetic-pharmacodynamic model (median prediction error: 3.9%).
