Simultaneous Analysis of Etizolam, Triazolam, and Their Metabolites in Biospecimens Using LCMS-9030
Benzodiazepines and their metabolites in the body are important analytes in the field of forensic toxicology and therefore more reliable toxicology test methods, such as liquid chromatography mass spectrometry (LC/MS), are needed. Since Etizolam, Triazolam, and their metabolites (alpha-Hydroxyetizolam, alpha-Hydroxytriazolam, and 4-Hydroxytriazolam) have similar structures or almost the same molecular weight, it is difficult to separate them using high performance liquid chromatography (HPLC) or by the difference in m/z values that can be detected by a quadrupole mass analyzer with nominal mass resolving power. In this experiment, we simultaneously analyzed Etizolam, Triazolam, and their metabolites using the Nexera™ X2 ultra high performance liquid chromatograph and LCMS-9030 high-resolution mass spectrometer.
Metabolome Analysis of Hydrophilic Metabolites in Saliva Using LCMS-8060NX Triple Quadrupole Mass Spectrometer
This report describes an example metabolome analysis of saliva performed using a high performance liquid chromatograph mass spectrometer (LC-MS-MS). Saliva is known to contain both oral bacteria and the metabolites produced by oral bacteria. The conditions under which saliva is stored prior to analysis can therefore affect the amounts of metabolites present in saliva due to the activity of these oral bacteria. We used metabolome analysis to investigate the effects of storage temperature on metabolites in saliva.
A Study of Toxicity Evaluation Using the iMScope TRIO - Analysis of Localization of Amiodarone in Rat Lungs
In drug discovery research, the analysis of the pharmacokinetics of candidate compounds provides important information not only in the elucidation of pharmacological mechanisms, but also from the viewpoint of toxicity assessment. In general, a method using autoradiography (ARG) and fluorescent dye is used, but with ARG the costs are high, and there have been concerns about the effects of using fluorescent agents as labeling agents on the pharmacokinetics. In recent years, the analytical technique of MS imaging attracted attention as a method that can detect data on the localization of candidate compounds without using a label. This method is expected to provide a breakthrough in drug discovery research as it can be used to analyze the localization of various substances without labeling, and to simultaneously analyze the unchanged drug and its metabolites using the same section. Here, we introduce an example of MS imaging analysis using the iMScope TRIO imaging mass microscope to compare the localization of the pathological findings with that of the amiodarone observed in lung tissue after administering amiodarone to rats.
Measurement of Enzymatic Activities in Dried Blood Spots with On-Line Solid Phase Extraction-LC/MS/MS System
Lysosomes are a type of intracellular organelle that uses a variety of hydrolytic enzymes to digest waste matter. To measure the enzymatic activity of lysosomes, methods using artificial fluorescent dyes and tandem mass spectrometry are used. Of these methods, tandem mass spectrometry offers the advantage of being able to measure multiple enzymatic activities at the same time. In this example, a protocol developed at the Meyer Children's Hospital, Mass Spectrometry, Clinical Chemistry and Pharmacology Laboratory (Florence, Italy) was used to measure the enzymatic activity in dried blood spots (DBS) using an online solid phase extraction (SPE) - liquid chromatograph - tandem mass spectrometer (LCMS-8050) system. Because using this system results in samples being cleaned up during SPE, samples can be inserted directly for measurement after enzymatic reaction, without any pretreatment processes.
Simultaneous Analysis of Chiral Amino Acids Produced by Intestinal Microbiota using LC/MS/MS
In recent years, it has become clear that the intestinal microbiota contributes to the preservation and promotion of the hosts’ health and attention has been focused on the relationship of the intestinal microbiota and metabolites with health and diseases. For this reason, it is extremely important to analyze the metabolites produced by the intestinal microbiota. D-amino acids are among the low molecular weight metabolites, and their physiological functions differ from those of L-amino acids. Amino acids have optical isomers (the D-isomer and L-isomer) and it has long been considered that only L-isomers are involved in the biological world. In recent years, however, it has been found that there are D-amino acids in the bodies of mammals, and their functions are attracting attention. To give an example, it is suggested that there is a relationship of D-serine with schizophrenia and amyotrophic lateral sclerosis. In this study, we comprehensively analyzed chiral amino acids in mouse colonic contents and blood plasma, using LC-MS/MS, and investigated D-amino acids produced by the intestinal microbiota.

Analysis of Short-Chain Fatty Acids/Organic Acids (3-NPH Derivatives) in Fecal Specimens from SPF and Antibiotic-Fed Mice
Here, analysis of the short-chain fatty acids and organic acids was performed using fecal specimens from SPF (Specific Pathogen Free) mice, in which physiological intestinal microbiota existed, and mice in which the level of intestinal microbiota was remarkably reduced by administration of an antibiotic. After collecting and weighing fecal specimens from the respective mice, the specimens were suspended in ethanol and the supernatant was recovered via centrifugal separation. This supernatant was subjected to derivatization by 3-NPH. As shown in Fig. 1, the derivative was then reacted at room temperature for 30 min using pyridine as a catalyst and carbodiimide as a condensing agent. After the reaction, the product was diluted with a methanol solution containing formic acid, and simultaneous analysis was performed with a LCMS-8060.

High-Sensitivity Analysis of Drugs in Ultra-Small Volume Plasma Samples Using Microflow LC/MS/MS
Pharmacokinetic (PK) studies of the metabolic fate of drugs in the body are conducted by preclinical and clinical tests as part of the drug development process. In preclinical PK studies, the concentration of drugs and their metabolites in biological samples obtained from animal experiments is analyzed by LC/MS/MS. However, since the size of the animal model generally limits the amount of sample volume that can be taken safely, a large number of animals and a significant volume of drug may be necessary for the evaluation, and this becomes an issue from the ethical and economic point of view. An effective approach to overcome those issues, together with the use of micro sampling technology, is the development of high sensitivity LC MS/MS methods that allows drug detection from a small amount of sample. This article introduces an example of a high-sensitivity microflow LC/MS/MS method, for the analysis of drugs in ultrasmall volume plasma samples.
Comprehensive Measurement of Metabolites Using GC-MS/MS and LC-MS/MS - An Application to the Research of the Intestinal Environment
Metabolomic analysis using a mass spectrometer generally employs a gas chromatograph mass spectrometer (GC-MS) or a liquid chromatography mass spectrometer (LC-MS) to comprehensively measure the metabolites (the metabolome) within a sample. It is necessary to select either a GC-MS or an LC-MS as appropriate for the target compound and the measurement purpose. A GC-MS features excellent robustness, and although derivatization is required for hydrophilic metabolites such as amino acids, organic acids, and sugars, it can comprehensively measure several hundred compounds in one measurement. An LC-MS on the other hand does not require derivatization. Capable of efficiently measuring specific metabolites (up to 100 compounds), it is optimal for the routine measurement of specific compounds. This article introduces a method for the comprehensive measurement of the primary metabolites in mouse feces using GC-MS/MS and LC-MS/MS.
Analysis of Plasma Metabolites Using Gas-Chromatography Tandem Mass Spectrometry System with Automated TMS Derivatization
Gas-Chromatography Tandem Mass Spectrometry (GC-MS/MS) is one of highly suitable techniques for metabolome analysis because of the high separation, reproducible retention times and sensitive selective mass detection. However, metabolites are commonly derivatized before GC-MS/MS analysis. In case of TMS derivatization, the samples should be analyzed within 24 hours after derivatization, because the TMS derivatives will deteriorate after 24 hours. Moreover, metabolome analysis requires the measurement of more than 100 samples. Therefore, an effective analysis procedure and a reduction of exposure of operators to toxic reagents are required. In order to improve analysis accuracy, efficiency and safety, an Automated TMS Derivatization GC-MS/MS System was developed. In this study, the system is evaluated for analysis of metabolites in human plasma.
