Abstract
Two novel abiraterone (Abi, 3β-OH-Abi) metabolites in human serum were identified as 3α-OH-Abi and Δ5-Abi (D5A). Both metabolites were confirmed by their retention times on LC/MS and their product-ion mass spectra on LC-MS/MS compared to those of authentic compounds, which were chemically synthesized. The plausible metabolic pathways of these two metabolites are as follows: Abi is first oxidized to D5A by 3β-hydroxysteroid dehydrogenase (3β-HSD) and then irreversibly converted to Δ4-Abi (D4A) by ∆5-∆4 isomerase. Presumably, D5A detection is difficult because of its rapid conversion to D4A and its low concentration in serum samples. In contrast, the low concentration 3α-OH-Abi was generated by reducing the remaining D5A using 3α-hydroxysteroid dehydrogenase (3α-HSD).

Abstract
The development of a novel therapy to overcome primary and acquired resistance to abiraterone is an unmet need. This study aimed to evaluate the efficacy and safety of adding 5α-reductase inhibitor dutasteride to abiraterone, explore proof of concept, and identify candidates suitable for combination therapy. This phase II, single-arm, and open-label study enrolled second-generation antiandrogen- and chemotherapy-naïve patients with castration-resistant prostate cancer. Patients received abiraterone and prednisolone for 4 weeks, followed by adding dutasteride. The primary end point was a 50% prostate-specific antigen response rate. Serum concentrations of abiraterone and its metabolites as well as HSD3B1 and SRD5A2 genotypes were measured. The association between drug metabolism and genotypes and their impact on the efficacy of combination therapy were assessed. Among 21 patients, 18 (85.7%) achieved ≥50% PSA reduction. Median time to treatment failure was not reached during the median follow-up of 15.4 months. No patients experienced grade ≥3 adverse events. Although dutasteride reduced serum 3-keto-5α-abiraterone concentrations, higher serum 3-keto-5α-abiraterone concentrations on combination therapy were associated with a shorter time to treatment failure. HSD3B1 and SRD5A2 genotypes were associated with serum Δ4-abiraterone and 3-keto-5α-abiraterone concentrations before adding dutasteride, respectively. Time to treatment failure was longer in patients with homozygous wild-type HSD3B1, but comparable between those with the SRD5A2 genotype. The promising outcomes of this study warrant further investigation of combination therapy in a randomized trial. Stratification by HSD3B1 and SRD5A2 genetic profiles might identify patients suitable for combination therapy.

Abstract
We developed and validated a liquid chromatography-electrospray ionization-time of flight/mass spectrometry method for the determination of abiraterone (Abi) and its metabolites (Δ4-Abi, 3-keto-5α-Abi, 3α-OH-5α-Abi and 3β-OH-5α-Abi) in human serum using Abi-d4 as the internal standard. As a pretreatment procedure of serum samples, solid-phase extraction based on a silica-gel cartridge was used. The relative recovery of Abi and its metabolites was over the ranges of 84.5 - 109.2% at a concentration of 6.0 ng mL-1 for Abi and 0.6 ng mL-1 for its metabolites. The method was free from matrix effects. The calibration curve of Abi was linear over the range of 2.0 - 400 ng mL-1 and those of its metabolites over the ranges 0.2 - 40 ng mL-1. The results of the intra- and inter-day accuracy and precision data were within the FDA acceptance criteria. The optimized method was applied for the determination of Abi and its metabolites in human serum after oral administration of Abi acetate.

Abstract
The interaction between prostate cancer cells and osteoblasts is essential for the development of bone metastasis. Previously, novel androgen receptor axis-targeted agents (ARATs) were approved for metastatic castration-naïve and non-metastatic castration-resistant prostate cancer (CRPC); both of which are pivotal for investigating the association between the bone microenvironment and tumors. The present study established a novel in vitro 3D microenvironment model that simulated the bone microenvironment of CRPC, and evaluated the drug susceptibility of ARATs and the efficacy of the combination of abiraterone and dutasteride. Green fluorescent protein-transferred C4-2 cells (a CRPC cell line) and red fluorescent protein-transferred human osteoblasts differentiated from human mesenchymal stem cells were co-cultured in chitosan nanofiber matrix-coated culture plates to simulate the 3D scaffold of the bone microenvironment. The growth of C4-2 was quantified using live-cell imaging and the Cell3 iMager duos analysis system. The growth of C4-2 colonies were quantified for a maximum of 30 days. The expression of TGF-β increased and promoted EMT in C4-2 cells co-cultured with osteoblasts, indicating resistance to ARATs. The IC50 of each drug and the combination effect of abiraterone and dutasteride were evaluated using this model. Combination treatment with abiraterone and dutasteride synergistically inhibited the growth of C2-4 colonies compared with individual investigational agents. This could be attributed to the reduction of 3-keto-5α-abiraterone, an androgen receptor agonist. The bone microenvironment model of the present study is unique and useful for evaluating new drug susceptibility testing in prostate cancer cells. This model may help to reveal the unknown mechanisms underlying micro- to clinical bone metastasis in prostate cancer.

Abstract
112 Background: Abiraterone (Abi) has been becoming a pivotal drug not only for metastatic castration resistant prostate cancer (mCRPC), but also for metastatic hormone sensitive prostate cancer (mHSPC). Abi is metabolized to delta-4 Abi (D4A), the strongest antitumor metabolite, by 3βHSD, and D4A is metabolized to 3-keto-5-α Abi, which acts as agonist to AR, by 5 α reductase. Reduction of 3-keto-5-α Abi by 5 α reductase inhibitor may increase the antitumor activity of Abi. Purpose of this study is to evaluate the efficacy and safety of the combination therapy of Abi and dutasteride (Duta), a 5 α reductase inhibitor, for the patients with CRPC. Methods: This is a non-randomized single-arm prospective phase II study. Patients with CRPC without any prior AR-targeting agent or docetaxel were recruited in this study with estimated enrollment of 20. Patients were treated with Abi (1,000 mg daily) and prednisone (5 mg daily) for 4 weeks, followed by the add-on of Duta (0.5 mg daily) for 12weeks. If PSA decline continued, combination treatment was allowed until progression. Abi and its metabolites including D4A and 3-keto-5-α Abi were measured by ESI-TOF-MS at baseline, 4, 6, 8, 12, 16, and 20 weeks, and the sample was collected at 2-4 hours after Abi administration. Primary endpoint was PSA decline >50%, and secondary endpoints were Time-to-treatment failure (TTF), and safety. Results: Totally 17 cases with CRPC (mean age: 78.4, initial PSA:92.6ng/ml, median Gleason score: 9) were recruited, and 14 were eligible for starting the combination therapy. Efficacy could be evaluated in 11 cases except 3 on-protocol treatment. Mean PSA decline of Abi/Duta combination therapy was significantly higher than that of monotherapy (p = 0.0143, 73 vs. 35 %). PSA decline>50% was noted in 36.4% for monotherapy, and 72.7% for combination therapy, respectively. Surprisingly, PSA decline>50% was significantly associated with lower Abi, D4A, and 3-keto 5 α Abi at 2 and 4 weeks after combination. Median TTF and progression (radiographic and/or PSA) was noted in 10.4 months (0.9-32), and 5 (45,4%), respectively with a median follow-up of 13.8 months. Progression was significantly associated with lower D4A, and 3-keto 5 a Abi at 4 and 8 weeks after combination therapy. Concerning safety, Grade 2 vertigo occurred in a case during Abi monotherapy period, while no adverse effect was found in combination therapy. Conclusions: Abi/Duta combination therapy seems to be theoretical to decrease AR-agonistic metabolite (3-keto 5 α Abi), and feasible for patients with first-line treatment of CRPC with lesser toxicity. Clinical trial information: UMIN000027795.

Abstract
Highly reactive α,β-unsaturated carbonyl compounds, such as acrolein (ACR), crotonaldehyde (CA) and methyl vinyl ketone (MVK), are environmental pollutants present in high concentrations in cigarette smoke. We have previously found that these carbonyl compounds in cigarette smoke extract (CSE) react with intracellular glutathione (GSH) to produce the corresponding GSH-ACR, GSH-CA and GSH-MVK adducts via Michael addition reaction. These adducts are then further reduced to the corresponding alcohol forms by intracellular aldo-keto reductases in highly metastatic mouse melanoma (B16-BL6) cells and then excreted into the extracellular fluid. This time, we conducted a similar study using sheep erythrocytes and found analogous changes in the sheep erythrocytes after exposure to CSE as those with B16-BL6 cells. This indicates similarity of the detoxification pathways of the α,β-unsaturated carbonyl compounds in sheep blood cells and B16-BL6 cells. Also, we found that the GSH-MVK adduct was reduced by aldose reductase in a cell-free solution to generate its alcohol form, and its reduction reaction was completely suppressed by pretreatment with epalrestat, an aldose reductase inhibitor, a member of the aldo-keto reductase family. In the presence of sheep blood cells, however, reduction of the GSH-MVK adduct was partially inhibited by epalrestat. This revealed that some member of the aldo-keto reductase superfamily other than aldose reductase is involved in reduction of the GSH-MVK adduct in sheep blood. These results suggest that blood cells, mainly erythrocytes are involved in reducing the inhalation toxicity of cigarette smoke via an aldo-keto reductase pathway other than that of aldose reductase.

Abstract
We investigated the anti-metastatic action of nicotine- and tar-removed cigarette smoke extract (CSE) on highly metastatic mouse Colon-26 cells using syngeneic BALB/c mice. Colon-26 cells were injected into the spleen of mice, cells were grown in the spleen as the primary lesion, and some metastasized from the spleen to liver and established a metastatic lesion. CSE (10, 30, and 100%) was intraperitoneally administered daily to the mice for 14 days after tumor inoculation. As a result, the relative spleen weights of CSE-administered mice did not differ significantly from those of the control mice. However, the relative liver weights of CSE 30%-administered mice significantly decreased compared to control mice. In order to identify the active component in CSE, we examined the action of methyl vinyl ketone (MVK) on the invasiveness of Colon-26 cells. MVK significantly reduced the invasiveness of cells. MVK may be a candidate active component of CSE.

Abstract
Cigarette smoke contains many harmful chemicals that contribute to the pathogenesis of smoking-related diseases such as chronic obstructive pulmonary disease, cancer, and cardiovascular disease. Many studies have been done to identify cytotoxic chemicals in cigarette smoke and elucidate the onset of the above-mentioned diseases caused by smoking. However, definitive mechanisms for cigarette smoke toxicity remain unknown. As candidates for cytotoxic chemicals, we have recently found methyl vinyl ketone (MVK) and acetic anhydride in nicotine/tar-free cigarette smoke extract (CSE) using L-tyrosine (Tyr), an amino acid with highly reactive hydroxyl group. The presence of MVK and acetic anhydride in CSE was confirmed by gas chromatography-mass spectrometry (GC/MS). We also found new reaction products formed in B16-BL6 mouse melanoma (B16-BL6) cells treated with CSE using LC/MS. These were identified as glutathione (GSH) conjugates of α,β-unsaturated carbonyl compounds, MVK, crotonaldehyde (CA), and acrolein (ACR), by the mass value and product ion spectra of these new products. ACR and MVK are type-2 alkenes, which are well known as electron acceptors and form Michael-type adducts to nucleophilic side chain of amino acids on peptides. These α,β-unsaturated carbonyl compounds may have a key role in CSE-induced cell death.

Abstract
Cigarette smoke contains many harmful chemicals, which contribute to the pathogenesis of smoking-related diseases such as chronic obstructive pulmonary disease, cancer and cardiovascular disease. The cytotoxicity of cigarette smoke is well documented, but the definitive mechanism behind its toxicity remains unknown. Ingredients in cigarette smoke are known to deplete intracellular glutathione (GSH), the most abundant cellular thiol antioxidant, and to cause oxidative stress. In the present study, we investigated the mechanism of cigarette smoke extract (CSE)-induced cytotoxicity in B16-BL6 mouse melanoma (B16-BL6) cells using liquid chromatography-tandem mass spectrometry. CSE and ingredients in cigarette smoke, methyl vinyl ketone (MVK) and crotonaldehyde (CA), reduced cell viability in a concentration-dependent manner. Also, CSE and the ingredients (m/z 70, each) irreversibly reacted with GSH (m/z 308) to form GSH adducts (m/z 378) in cells and considerably decreased cellular GSH levels at concentrations that do not cause cell death. Mass spectral data showed that the major product formed in cells exposed to CSE was the GSH-MVK adduct via Michael-addition and was not the GSH-CA adduct. These results indicate that MVK included in CSE reacts with GSH in cells to form the GSH-MVK adduct, and thus a possible reason for CSE-induced cytotoxicity is a decrease in intracellular GSH levels.

Abstract
Cigarette smoke, a collection of many toxic chemicals, contributes to the pathogenesis of smoking-related diseases such as chronic obstructive pulmonary disease and cancer. Much work has been done on the chemical analysis of ingredients in cigarette smoke, but there are few reports on the active ingredients that can modify biomolecules. We used a sensitive liquid chromatography-mass spectrometry (LC/MS) and LC/MS/MS method to show that L-tyrosine (Tyr), an amino acid with a highly reactive hydroxyl group, readily reacts with cigarette smoke extract (CSE) at body temperature (37°C) to form various Tyr derivatives. Among these derivatives were N-(3-oxobutyl)-Tyr and two acetylated compounds, N-acetyl-Tyr and O-acetyl-Tyr, which were synthesized by reaction of Tyr with methyl vinyl ketone and acetic anhydride, respectively, at 37°C. The presence of methyl vinyl ketone and acetic anhydride in CSE was confirmed by gas chromatography-mass spectrometry (GC/MS). These results indicate that Tyr can easily react with active ingredients in CSE. The present analytical methods should aid the search for active ingredients in cigarette smoke.

Abstract
Sorbic acid (SA: CH(3)-CH=CH-CH=CH-COOH) is one of the widely used food preservatives, although there have been some reports of its toxic activity, for example, on DNA and skin cells. In order to examine the effects of SA on mammalian tissues, we have developed a highly sensitive analytical method using LC/MS/MS with positive and negative ion mode electrospray ionization (ESI). In a previous study, we found that a nonacidic eluent offers better ionization efficiency than acids or their ammoniun salts. However, optimal results could not be obtained because the anion form of SA is poorly retained on a conventional reversed phase column. To resolve this problem, we chose a new type of column and used high-resolution mass spectrometry and positive ion mode analysis. There have only been a few reports using these methods in the positive mode, for example derivatized SA, because acid compounds such as SA are usually used in the negative ion mode. However, a new type of low-carbon-content and polar-endcapped C18 phase column was developed for better separation of SA from the matrix. High-resolution selected reaction monitoring (SRM) gave the best signal to noise ratio in normal-resolution SRM. In the positive ion mode, the CH(3)OH-0.05% HCOOH/0.1% CH(3)COOH eluent system yielded the best ionization efficiency. We propose a highly sensitive and simple analysis using a two-ion-mode ESI SRM method. Such systems should allow quantification of the amount of SA in or around the cells, without the need for pretreatment such as solid phase extraction.

Abstract
The anti-inflammatory activities of several novel oximes and O-acyl oximes that we synthesized have been reported based on carrageenan-induced rat foot-pad swelling assay and histamine-induced rat vascular permeability assay. A cyclooxygenase (COX)-1 inhibitory effect has also been reported for 4'-piperidinoacetophenone and 4'-morpholinoacetophenone oximes and their O-acyl derivatives. To further search for more effective non-steroidal anti-inflammatory or anti-allergic drugs, 1-hydroxylamino-1-(4'-piperidinophenyl) ethane (P-HA) and 1-hydroxylamino-1-(4'-morpholinophenyl) ethane (M-HA) were synthesized from the corresponding oximes with sodium cyanoborohydride, and N,O-diacetyl hydroxylamines (P-HA-Ac and M-HA-Ac) were prepared from these hydroxylamines using acetyl chloride. These hydroxylamines and N,O-diacetyl hydroxylamines clearly exhibited inhibitory effects on mouse carrageenan-induced foot-pad swelling induced by oral administration (150, 37.5 mg/kg). An oral dose of P-HA-Ac (150 mg/kg) significantly inhibited the mouse anaphylactic reaction to ovalbumin measured by the abdominal wall (AW) method. Percutaneous administration of P-HA and M-HA significantly inhibited 2,4-dinitrofluorobenzene (DNFB)-induced contact hypersensitivity reaction (type IV) in mice at a dose of 0.5 and 0.1 mg/ear, respectively. All tested hydroxylamines and N,O-diacetyl hydroxylamines clearly inhibited both COX-1 and COX-2 enzyme activities with IC(50) values of 1.9-28.7 and 1.6-2.9 micro M against COX-1 and COX-2, respectively. Hydroxylamines (P-HA and M-HA) also showed a 5-lipoxygenase inhibitory effect.

Abstract
Hydroxylamines gradually undergo oxidation to their oximes on being dissolved in organic solvent (e.g. methanol). This phenomenon was followed by (1)H-NMR and liquid chromatography-mass spectrometry (LC-MS). The oxidation rate was estimated from the peak area observed on the mass chromatogram at the protonated molecule or fragment ion on LC-atmospheric pressure chemical ionization (APCI)-MS. The results showed that the oxidation rate of hydroxylamines depended on the solvent type.

Abstract
Rhein anthrone, the active metabolite of sennosides A and B, stimulated PGE2 release into the mouse colonic lumen. At 6.24 mg kg-1, it decreased net water and Na+ absorption significantly in the case of water, but could not reverse the net absorption in mouse ligated colon, although it enhanced net K+ secretion. Pretreatment with indomethacin diminished the effects of rhein anthrone except on K+ net secretion. Rhein anthrone or PGE2 markedly stimulated mucus secretion and synthesis in mouse ligated colon. The enhanced mucus secretion and synthesis induced by rhein anthrone were significantly suppressed by pretreatment with indomethacin. Our results have shown that the colonic secretion of water and electrolytes mediated by PGE2 is partly involved in the rhein anthrone-induced diarrhoea but that in mice, the mucoid diarrhoea induced by rhein anthrone results mainly from PGE2-mediated mucus synthesis and secretion in the colon.
