Abstract
Background: The population of blast cells among peripheral blood mononuclear cells (PBMCs) obtained from patients is a desirable specimen for analyzing gene expression in diseases including acute myeloid leukemia. Although the enrichment of blast cells often needs to be performed at a central laboratory, acceptable conditions for sample transport from clinical sites remain to be established. Methods: We evaluated storage temperature, duration, and tube type before initiating sample processing for the analysis of cluster of differentiation (CD)33+ myeloid cells among PBMCs as an alternative to CD34+/CD33+ blast cells. Results: CD33+ myeloid cells were successfully purified by MACS. The cell viability and the RNA integrity were sustained during storage up to 48 hours before sample processing. Storage at 4°C had minimal effects on gene expression, whereas storage at room temperature induced the senescence pathway, characterized by the expression of stress-inducible genes. A CPT tube was also better than an ethylenediaminetetraacetic acid tube for minimizing gene expression change. Conclusions: Our study provided important clues for establishing a sample handling approach for gene expression analysis with purified cell fractions from human PBMCs. To keep the variation of gene expression to a minimum, samples should be delivered at 4°C within 48 hours before processing.

Abstract
G-protein-coupled receptor class 5 member D (GPRC5D) is detected in malignant plasma cells in approximately 90% of patients diagnosed with multiple myeloma (MM). Here, we constructed BsAb5003, a novel humanized bispecific monoclonal antibody targeting CD3 and GPRC5D, and evaluated its therapeutic impact on MM. BsAb5003 induced specific cytotoxicity of GPRC5D-positive MM cells with concomitant T cell activation and cytokine release. The efficacy of BsAb5003 was associated with GPRC5D expression levels in MM cell lines. Flow cytometry analysis of bone marrow mononuclear cells (BMMNCs) from 49 MM patients revealed that GPRC5D was expressed in a wide population of MM patients, including heavily treated and high-risk patients. In ex vivo assays using BMMNCs, BsAb5003 induced potent efficacy against CD138 + MM cells in both newly diagnosed and relapsed/refractory patient samples in a GPRC5D expression-dependent manner. BsAb5003 significantly enhanced T cell activation and cytokine production in combination with immunomodulatory drugs (IMiDs) against MM cell lines. BsAb5003 also demonstrated significant inhibition of in vivo tumor growth by recruiting T cells. Taken together, these results suggest that T cell-redirecting bispecific antibody targeting GPRC5D as monotherapy and combination therapy with IMiDs could be a highly potent and effective treatment approach for a wide population of MM patients.

Abstract
Vitamin Ks are expected to contribute bone and cardiovascular health. Especially, menaquinone-7 has a higher bioavailability and a longer half-life than other vitamin Ks in the human body. However, their low water-solubility limits their application. On the other hand, Bacillus subtilis natto produces a water-soluble complex, which comprises menaquinone-7 and peptides. The peptide named K-binding factor (KBF) has been reported as the main component of the complex. In the present, the structural characteristics of KBF were studied. Mass spectrometry showed significant peaks at m/z = 1050, while the previous PAGE suggested that molecular weight of KBF was ~ 3k. Amino acid analysis revealed that the 1k peptides were the various combinations of nine amino acids, among which Asx, Glx, Val, Leu and Met were found to be the most abundant. The peptides could serve as detergent properties. The 1k peptides could be isolated by reverse-phase high performance liquid chromatography. The bundle of three 1k detergent-like peptides would participate to the micelle structure containing menqauinone-7 inside. In conclusion, a basic unit of KBF would be the ~ 1k peptides, and the three basic unit assemble to the ~ 3k bundle, then the bundle form a water-soluble micelle including menqauinone-7 inside.

Abstract
Axicabtagene ciloleucel (axi-cel) is an autologous, CD19-targeting chimeric antigen receptor T‑cell therapy. We recently reported the 3-month follow-up results of a phase 2, multicenter, open‑label, single-arm study of axi-cel in Japanese patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) (JapicCTI-183914). Here, we present 1-year efficacy and safety data and biomarker analysis data regarding mechanisms of resistance to axi-cel. Primary and secondary endpoints included investigator-assessed objective response rate (ORR), serious adverse events, and treatment-emergent adverse events. Axi-cel pharmacokinetics were also examined. Biomarker analysis was performed by cytokine measurement, immunohistochemistry, RNA sequencing, and whole-exome sequencing. At a median follow-up of 13.4 months, ORR was 86.7% (13/15 patients), and the complete response (CR) rate improved to 53.3% (8/15 patients) due to response conversion. Seven patients experienced disease progression, and one achieved CR after re-treatment with axi-cel. No new safety concerns were detected. Plausible resistance mechanisms to axi-cel varied among patients but included CD19 downregulation, programmed death-ligand 1 upregulation, and increased macrophage and angiogenesis signatures. The 1-year efficacy and safety of axi-cel were confirmed in Japanese patients with R/R LBCL. Resistance to treatment may involve multiple factors, including target antigen loss and an unfavorable tumor environment.Clinical trial registration: Japan Clinical Trials Information; JapicCTI-183914.

Abstract
Long-term survival in patients with acute myeloid leukemia (AML) remains low, and current treatment modalities are inadequate. Milademetan (DS-3032, RAIN-32), a small-molecule specific murine double minute 2 inhibitor, has shown a p53 status-dependent antitumor effect in vitro studies. This is the first phase I study report of milademetan monotherapy in relapsed/refractory (R/R) AML patients evaluating the safety, tolerability, pharmacokinetics, and preliminary tumor response for further clinical development. Fourteen patients received 90 (starting dose, n = 4), 120 (n = 6), or 160 mg (n = 4) of oral milademetan once daily in a 14/28 treatment cycle. The median total treatment duration was 1.5 cycles. Dose-limiting toxicity did not occur, and the maximum tolerated dose was not reached. Thus, the recommended dose was defined as 160 mg. The most common adverse events (AEs) were decreased appetite (64.3%), febrile neutropenia (50%), nausea (42.9%), and anemia (35.7%). No deaths or AEs leading to treatment discontinuation occurred. Five serious treatment-emergent AEs occurred in 4 patients. Plasma concentration increased linearly with milademetan dose. However, trends in the safety and efficacy of oral milademetan in patients with R/R AML warrant further clinical investigation. This study can inform future milademetan studies in hematologic malignancies.

Abstract
A structure-activity relationship (SAR) study towards novel ACC1-selective inhibitors was carried out by modifying the molecular length of the linker in biaryl derivative 1 g, an ACC1/2 dual inhibitor. Ultimately, this leads us to discover novel phenoxybenzyloxy derivative 1i as a potent ACC1-selective inhibitor. Further chemical modification of this scaffold to improve cellular potency as well as physicochemical and pharmacokinetic (PK) properties produced N-2-(pyridin-2-ylethyl)acetamide derivative 1n, which showed highly potent ACC1-selective inhibition as well as sufficient PK profile for further in vivo evaluations. Oral administration of 1n significantly reduced the concentration of malonyl-CoA in HCT-116 xenograft tumors at doses of 100 mg/kg. Accordingly, our novel series of potent ACC1-selective inhibitors represents a set of useful orally-available research tools, as well as potential therapeutic agents for cancer and fatty acid-related diseases.

Abstract
Acute myeloid leukemia (AML) patients with FLT3-ITD mutations have a high risk of relapse and death. FLT3 tyrosine kinase inhibitors improve overall survival, but their efficacy is limited and most patients who relapse will ultimately die of the disease. Even with potent FLT3 inhibition, the disease persists within the bone marrow (BM) microenvironment, mainly due to BM stroma activating parallel signaling pathways that maintain pro-survival factors. BET inhibitors suppress pro-survival factors such as MYC and BCL2, but these drugs thus far have shown only limited single-agent clinical potential. We demonstrate here, using pre-clinical and clinical correlative studies, that the novel 4-azaindole derivative, PLX51107, has BET-inhibitory activity in vitro and in vivo. The combination of BET and FLT3 inhibition induces a synergistic anti-leukemic effect in a murine xenograft model of FLT3- ITD AML, and against primary FLT3-ITD AML cells co-cultured with BM stroma. Using suppression of MYC as a surrogate for BET inhibition, we demonstrate BET inhibition in human patients. The short plasma half-life of PLX51107 results in intermittent target inhibition to promote tolerability while overcoming the protective effect of the microenvironment. Mechanistically, the synergistic cytotoxicity is associated with suppression of key survival genes such as MYC. These data provide the scientific rationale for a clinical trial of a BET plus FLT3 inhibitor for the treatment of relapsed/refractory FLT3-ITD AML. A clinical trial of PLX51107 as monotherapy in patients with different malignancies is underway and will be reported separately.

Abstract
Abstract
Introduction: We evaluated the impact of baseline (BL) co-mutations and FLT3-ITD VAF on overall survival (OS) and response (composite complete remission [CRc]) to quizartinib and SC in the phase III QuANTUM-R trial.
Methods: We analyzed 37 recurrently mutated genes in AML in BL samples from 304 patients (pts) (83% of ITT population) with R/R FLT3-ITD-positive AML using next-generation sequencing and a customized Archer® Core Myeloid panel. Positive mutation status was defined as ≥1 mutation detected in the gene region using a VAF cutoff of 2.7%. FLT3-ITD VAF was measured by the Navigate BioPharma FLT3 Mutation Assay (polymerase chain reaction-based, VAF cutoff of 3%). Low and high FLT3-ITD VAF were defined as ≤25% and >25%, respectively.
Results: In addition to FLT3-ITD, the prevalence of key BL co-mutations were 59.9% for DNMT3Amut and 55.3% for NPM1mut. Pts with DNMT3Amut treated with quizartinib had significantly longer OS vs SC (6.3 and 5.4 mos, respectively; hazard ratio [HR], 0.652), p<.05). Pts with NPM1mut treated with quizartinib had a higher CRc rate than with SC, but similar OS (5.1 vs 4.7 mos, respectively; HR, 0.954, p=.82). Pts with NPM1wt/DNMT3Amut treated with quizartinib had the highest CRc rate and longest median OS (9.0 and 4.5 mos, respectively; HR, 0.239, p=.003). OS benefit with quizartinib relative to SC was more pronounced among pts with high FLT3-ITD VAF than low FLT3-ITD VAF. The OS benefit with quizartinib in pts with NPM1wt/DNMT3Amut was maintained in both low and high FLT3-ITD VAF groups. Similarly, for other DNMT3A/NPM1 co-permutations, OS in both low and high FLT3-ITD VAF groups was consistent with OS in the co-mutation group.
Conclusions: Key co-mutations identified here potentially affect treatment response and OS with quizartinib vs SC. Our results suggest that molecular subsets of R/R AML pts may particularly derive clinical benefit from quizartinib.

Abstract
A 76-year-old Japanese man was admitted to hospital for treatment of fever and skin lesion at the implantation site of his pacemaker. During his hospitalization, vancomycin-intermediate Staphylococcus aureus (MIC 4 μg/mL) with reduced susceptibility to daptomycin was isolated from venous blood. This isolate was identified as methicillin-resistant S. aureus with SCCmec IV and was genotyped as sequence type 81, coa VIIa and spa type t7044, harbouring blaZ, aac(6′)-aph(2″) and enterotoxin(-like) genes sea, seb, sek, sel, selx and selw. The patient was successfully treated with daptomycin, minocycline and sulfamethoxazole/trimethoprim. We describe the identification of sequence type 81/SCCmec IV vancomycin-intermediate S. aureus from pacemaker-associated septicaemia.

Abstract
In our effort to explore the potential of ACC1-selective inhibitor as in vivo probe molecule, a series of 1,3-benzoxazole derivatives was synthesized. Previously, we reported a series of novel bicyclic and monocyclic ACC1-selective inhibitors. Among them, compound 1a exhibited highly potent cellular activity (acetate uptake IC50 = 0.76 nM) as well as promising in vivo PD efficacy. However, compound 1a caused severe body weight reduction in repeated dose administration in the mouse model. Since 1a showed potent inhibitory activity against mouse ACC1 as well as strong inhibition of mouse ACC2, we further examined a series of 1a analogues in order to reduce undesirable body weight change. The replacement of acetamide moiety with ureido moiety dramatically improved selectivity of mouse ACC1 against ACC2. In addition, analogue 1b displayed favorable bioavailability in mouse cassette dosing PK study, hence in vivo PD studies were also carried out. Oral administration of 1b significantly reduced the concentration of malonyl-CoA in HCT-116 xenograft tumors at doses of more than 30 mg/kg. Furthermore, compound 1b showed significant antitumor efficacy in 786-O xenograft mice at an oral dose of 30 mg/kg (T/C = 0.5%). Accordingly, our novel potent ACC1-selective inhibitor represents a set of useful orally-available research tools, as well as potential therapeutic agents particularly in terms of new cancer therapies.

Abstract
We initiated our structure-activity relationship (SAR) studies for novel ACC1 inhibitors from 1a as a lead compound. Our initial SAR studies of 1H-Pyrrolo[3,2-b]pyridine-3-carboxamide scaffold revealed the participation of HBD and HBA for ACC1 inhibitory potency and identified 1-methyl-1H-pyrrolo[3,2-b]pyridine-3-carboxamide derivative 1c as a potent ACC1 inhibitor. Although compound 1c had physicochemical and pharmacokinetic (PK) issues, we investigated the 1H-pyrrolo[3,2-b]pyridine core scaffold to address these issues. Accordingly, this led us to discover a novel 1-isopropyl-1H-pyrrolo[3,2-b]pyridine-3-carboxamide derivative 1k as a promising ACC1 inhibitor, which showed potent ACC1 inhibition as well as sufficient cellular potency. Since compound 1k displayed favorable bioavailability in mouse cassette dosing PK study, we conducted in vivo Pharmacodynamics (PD) studies of this compound. Oral administration of 1k significantly reduced the concentration of malonyl-CoA in HCT-116 xenograft tumors at a dose of 100 mg/kg. Accordingly, our novel series of potent ACC1 inhibitors represent useful orally-available research tools, as well as potential therapeutic agents for cancer and fatty acid related diseases.

Abstract
SummaryIn the present study, the activation mechanism of fibrinolytic enzyme system in plasma by human pancreatic elastase was investigated. It was confirmed that human pancreatic elastase not only converted the co-existing plasminogen to low molecular weight-plasminogen which could be easily activated by the activator, but also inhibited α2-macroglobulin and α2-plasmin inhibitor which are antiactivators or fast reacting antiplasmins, and consequently, induced the activation of the fibrinolytic enzyme system in plasma.

Abstract
SummaryPapain treatment of human urinary trypsin inhibitor (UTI67; mol. wt. 43,000 by SDS-polyacrylamide gel electrophoresis, specific activity 1,897 U/mg protein) produced four new protease inhibitors, which were highly purified by gel chromatography on Sephadex G-100 and isoelectric focusing. The purified inhibitors (UTI26, UTI9-I, UTI9-II, and UTI9-III) were shown to be homogeneous by polyacrylamide disc gel electrophoresis, and had apparent molecular weights of 26,000, 9,000, 9,000, and 9,800, respectively, by sodium dodecyl sulfate gel electrophoresis. During enzymatic degradation of UTI67, the amino acid compositions changed to more basic, and the isoelectric point increased from pH 2.0 (UTI67) to pHs 4.4, 5.2, 6.6, and 8.3 (UTI26, UTI9-I, UTI9-II, and UTI9-III), respectively. Both the parent and degraded inhibitors had anti-plasmin activity as well as antitrypsin and anti-chymotrypsin activities. Much higher anti-plasmin/anti-trypsin and anti-plasmin/anti-chymotrypsin activities were observed in the degraded inhibitors than in the parent UTI67. They competitively inhibited human plasmin with Ki values of 1.13 X 10-7 - 2.12 X 10-6 M (H-D-Val-Leu-Lys-pNA substrate). The reactions were very fast and the active site of the inhibitors to plasmin was thought to be different from that to trypsin or chymotrypsin.

Abstract
SummaryThe esterase activity of highly purified human urokinase on Nα-acetylglycyl-L-lysine methyl ester is strongly inhibited by 1 × 10-5tol × 10“2MCu++, Hg++, Ni++, Co++, Fe+++, and Mn++ solutions, whereas Na+, K+, Ca++, and Mg++ are weakly effective. This inhibition is parallel with the inhibition of activation of plasminogen by urokinase. There is no simple linear relation between inhibition and ion concentration. Addition of ethylenediaminetetraacetate or electrodialysis fully reactivates the inhibited enzyme. These results are discussed in relation to similar effects of ions on trypsin.

Abstract
SummarySix different plasmins were prepared by incubating human plasminogen with various amounts of streptokinase or urokinase. It was confirmed that the six different plasmins possessed similar caseinolytic activities, and the inhibitory effects of α 1-antitrypsin on caseinolytic activities of the six different plasmins were all the same. On the other hand, interactions between the six different plasmins and α2-macroglobulin were complicated. Plasmins activated by cleavage of plasminogen were almost immediately or effectively inhibited by α2-macroglobulin. However, plasmin activated by complex formation of plasminogen with streptokinase was not so immediately or effectively inhibited by α2- macroglobulin. It was supposed that the difference between these two results on the interaction between plasmin and α2-macroglobulin might be due to the difference in molecular form of plasmin. In the present study, it was also confirmed that streptokinase or urokinase, in free form in the reaction mixture, interfered with the interaction between plasmin and α2-macroglobulin. The cause for such interference was discussed.

Abstract
Elucidating the bioactive compound modes of action is crucial for increasing success rates in drug development. For anticancer drugs, defining effective drug combinations that overcome resistance improves therapeutic efficacy. Herein, by using a biologically annotated compound library, we performed a large-scale combination screening with Stearoyl-CoA desaturase-1 (SCD1) inhibitor, T-3764518, which partially inhibits colorectal cancer cell proliferation. T-3764518 induced phosphorylation and activation of AMPK in HCT-116 cells, which led to blockade of downstream fatty acid synthesis and acceleration of autophagy. Attenuation of fatty acid synthesis by small molecules suppressed the growth inhibitory effect of T-3764518. In contrast, combination of T-3764518 with autophagy flux inhibitors synergistically inhibited cellular proliferation. Experiments using SCD1 knock-out cells validated the results obtained with T-3764518. The results of our study indicated that activation of autophagy serves as a survival signal when SCD1 is inhibited in HCT-116 cells. Furthermore, these findings suggest that combining SCD1 inhibitor with autophagy inhibitors is a promising anticancer therapy.

Abstract
The purpose of this study was to investigate the changes in tongue-palatal contact patterns using electropalatography (EPG) before and after sagittal split ramus osteotomy (SSRO) in patients with mandibular prognathism. Nine clients who underwent SSRO for mandibular setback and seven control subjects were participated in this study. Tongue-palatal contact patterns for /t/, /s/ and /k/ production were investigated using EPG before surgery and 3 months after surgery. The mean value of whole total of palate contact (WT) in the maximum contact frame was examined before and after SSRO. The correlation quantity between the change of center of gravity (COG) value and the amount of mandibular setback was also evaluated. The mean value of WT for /t/ and /s/ significantly increased after SSRO, and the EPG pattern became normal. However, a remarkable change in WT for /k/ was not observed, and the mean value was significantly larger in the SSRO group before and after surgery than in the control group. A negative correlation between COG variation and the amount of mandibular setback for /t/ and positive correlation for /s/ was observed. This study demonstrated that tongue-palatal contact patterns for /t/ and /s/ articulation improved clearly after SSRO. There was a significant correlation between COG variation and the amount of mandibular setback. However, no significant change was detected through perceptual assessment before and after SSRO. Further investigation is needed to determine whether these results will change over time.

Abstract
A lead compound A was identified previously as an stearoyl coenzyme A desaturase (SCD) inhibitor during research on potential treatments for obesity. This compound showed high SCD1 binding affinity, but a poor pharmacokinetic (PK) profile and limited chemical accessibility, making it suboptimal for use in anticancer research. To identify potent SCD1 inhibitors with more promising PK profiles, we newly designed a series of 'non-spiro' 4, 4-disubstituted piperidine derivatives based on molecular modeling studies. As a result, we discovered compound 1a, which retained moderate SCD1 binding affinity. Optimization around 1a was accelerated by analyzing Hansch-Fujita and Hammett constants to obtain 4-phenyl-4-(trifluoromethyl)piperidine derivative 1n. Fine-tuning of the azole moiety of 1n led to compound 1o (T-3764518), which retained nanomolar affinity and exhibited an excellent PK profile. Reflecting the good potency and PK profile, orally administrated compound 1o showed significant pharmacodynamic (PD) marker reduction (at 0.3mg/kg, bid) in HCT116 mouse xenograft model and tumor growth suppression (at 1mg/kg, bid) in 786-O mouse xenograft model. In conclusion, we identified a new series of SCD1 inhibitors, represented by compound 1o, which represents a promising new chemical tool suitable for the study of SCD1 biology as well as the potential development of novel anticancer therapies.

Abstract
Most cancer cells are characterized by elevated lipid biosynthesis. The rapid proliferation of cancer cells requires de novo synthesis of fatty acids. Stearoyl-CoA desaturase-1 (SCD1), a key enzyme for lipogenesis, is overexpressed in various types of cancer and plays an important role in cancer cell proliferation. Therefore, it has been studied as a candidate target for cancer therapy. In this study, we demonstrate the pharmacological properties of T-3764518, a novel and orally available small molecule inhibitor of SCD1. T-3764518 inhibited stearoyl-CoA desaturase-catalyzed conversion of stearoyl-CoA to oleoyl-CoA in colorectal cancer HCT-116 cells and their growth. Further, it slowed tumor growth in an HCT-116 and a mesothelioma MSTO-211H mouse xenograft model. Comprehensive lipidomic analyses revealed that T-3764518 increases the membrane ratio of saturated: unsaturated fatty acids in various lipid species such as phosphatidylcholines and diacylglycerols in both cultured cells and HCT-116 xenografts. Treatment-associated lipidomic changes were followed by activated endoplasmic reticulum (ER) stress responses such as increased immunoglobulin heavy chain-binding protein expression in HCT-116 cells. These T-3764518-induced changes led to an increase in cleaved poly (ADP-ribose) polymerase 1 (PARP1), a marker of apoptosis. Additionally, bovine serum albumin conjugated with oleic acid, an SCD1 product, prevented cell growth inhibition and ER stress responses by T-3764518, indicating that these outcomes were not attributable to off-target effects. These results indicate that T-3764518 is a promising new anticancer drug candidate.

Abstract
Inhibitors of apoptosis proteins (IAPs) are antiapoptotic regulators that block cell death, and are frequently overexpressed in several human cancers, where they facilitate evasion of apoptosis and promote cell survival. IAP antagonists are also known as second mitochondria-derived activator of caspase (SMAC)-mimetics, and have recently been considered as novel therapeutic agents for inducing apoptosis, alone and in combination with other anticancer drugs. In this study, we showed that T-3256336, the orally available IAP antagonist has synergistically enhances the antiproliferative effects of the NEDD8-activating enzyme (NAE) inhibitor pevonedistat (TAK-924/MLN4924), and these effects were attenuated by a TNFα-neutralizing antibody. In the present mechanistic analyses, pevonedistat induced TNFα mRNA and triggered IAP antagonist-dependent extrinsic apoptotic cell death in cancer cell lines. Furthermore, synergistic effects of the combination of T-3256336 and pevonedistat were demonstrated in a HL-60 mouse xenograft model. Our findings provide mechanistic evidence of the effects of IAP antagonists in combination with NAE inhibitors, and demonstrate the potential of a new combination therapy for cancer.

Abstract
Inhibitors of apoptosis proteins (IAPs) are a family of antiapoptotic regulators that have attracted attention as potential targets for cancer therapeutics. Although recent studies have revealed that small-molecule IAP antagonists induce tumor selective cell death in an autocrine tumor necrosis factor (TNF)α-dependent manner, the single-agent efficacy of IAP antagonists is restricted to a small subset of cancer cells. In this study, we showed that the single-agent activity of T-3256336 was limited to a few cancer cell lines in vitro, and these cell lines were defined by relatively high levels of TNFα mRNA expression. However, some other cancer cells, including PANC-1 cells, become drastically sensitive to T-3256336 when costimulated with exogenous TNFα. In PANC-1 mouse xenograft models, the administration of T-3256336 increased levels of several cytokines including TNFα and lead to tumor regression as a single agent, which was attenuated by the neutralization of circulating mouse TNFα with an antibody. These results suggest dual roles of IAP antagonists, increase systemic cytokines including TNFα, and sensitization of tumors to IAP antagonist-induced death.

Abstract
Different crystal packing of hydrates from anhydrate crystals leads to different physical properties, such as solubility and stability. Investigation of the potential of varied hydrate formation, and understanding the stability in an anhydrous/hydrate system, are crucial to prevent an undesired transition during the manufacturing process and storage. Only one anhydrous form of T-3256336, a novel inhibitor of apoptosis (IAP) protein antagonist, was discovered during synthesis, and no hydrate form has been identified. In this study, we conducted hydrate screening such as dynamic water vapor sorption/desorption (DVS), and the slurry experiment, and characterized the solid-state properties of anhydrous/hydrate forms to determine the most desirable crystalline form for development. New hydrate forms, both mono-hydrate and hemi-hydrate forms, were discovered as a result of this hydrate screening. The characterization of two new hydrate forms was conducted, and the anhydrous form was determined to be the most desirable development form of T-3256336 in terms of solid-state stability. In addition, the stability of the anhydrous form was investigated using the water content and temperature controlled slurry experiment to obtain the desirable crystal form in the crystallization process. The water content regions of the stable phase of the desired form, the anhydrous form, were identified for the cooling crystallization process.

Abstract
Mesenchymal stem cells (MSCs) can be used for regeneration of various organs and tissues. A previous study revealed that cryopreserved MSCs, which were frozen by a programmed freezer with a magnetic field (Cells Alive System: CAS) and cryopreserved for 7 days in a -150°C deep freezer, can maintain high survival and proliferation rates while retaining both adipogenic and osteogenic differentiation abilities. The purpose of this study was to examine MSC viability and tissue regenerative ability after long-term cryopreservation using a CAS freezer. MSCs were isolated from rat femora bone marrow and cryopreserved in a -150°C deep freezer (CAS group) or directly cryopreserved in a deep freezer (Direct group). After 3 years, the cells were thawed and the number of viable cells was counted. Cell proliferation was also examined after 14 days in culture. For histological examination, forty 4-week-old Fischer 344 male rats received bone and sagittal suture defects with a diameter of 6.0mm, and MSCs (CAS or Direct group) cryopreserved for 1 year were grafted with membranes. Non-cryopreserved MSCs (Control group) were transplanted to an additional twenty rats. The rats were sacrificed at 4, 8, 16, and 24 weeks after surgery. The parietal bones, including the sagittal suture, were observed under a light microscope and the extent of bone regeneration was measured. Our results indicate that MSCs survival and proliferation rates were significantly higher in the CAS group than in the Direct group. In the Control and CAS groups, a large amount of new bone formation and a suture-like gap was identified 24 weeks after transplantation, whereas only a small amount of new bone formation was observed in the Direct group. These results suggest that the CAS freezer is amenable to long-term cryopreservation of MSCs, which can be applied to the regeneration of various tissues, including bone tissue with suture-like gap formation.

Abstract
Nattokinase (NK) is a strong fibrinolytic enzyme, which is produced in abundance by Bacillus subtilis natto. Although NK is a member of the subtilisin family, it displays different substrate specificity when compared with other subtilisins. The results of molecular simulations predict that hydrogen arrangements around Ser221 at the active site probably account for the substrate specificity of NK. Therefore, neutron crystallographic analysis should provide valuable information that reveals the enzymatic mechanism of NK. In this report, the X-ray structure of the non-hydrogen form of undeuterated NK was determined, and the preparation of deuterated NK was successfully achieved. The non-hydrogen NK structure was determined at 1.74 Å resolution. The three-dimensional structures of NK and subtilisin E from Bacillus subtilis DB104 are near identical. Deuteration of NK was carried out by cultivating Bacillus subtilis natto in deuterated medium. The D2O resistant strain of Bacillus subtilis natto was obtained by successive cultivation rounds, in which the concentration of D2O in the medium was gradually increased. NK was purified from the culture medium and its activity was confirmed by the fibrin plate method. The results lay the framework for neutron protein crystallography analysis.

Abstract
We recently reported the discovery of octahydropyrrolo[1,2-a]pyrazine A as a lead compound for an inhibitor of apoptosis proteins (IAP) antagonist. To develop IAP antagonists with favorable PK profiles, we designed novel tri-cyclic compounds, octahydro-1H-cyclopropa[4,5]pyrrolo[1,2-a]pyrazines 1 and 2 based on co-crystal structural analysis of A with cellular IAP-1 (cIAP-1). The additional cyclopropane moiety was used to block the predicted metabolic site of compound A without detriment to the binding affinity for cIAP. Compounds 1 and 2 were stereoselectively synthesized via intermediates 4a and 5b', which were obtained by Simmons-Smith cyclopropanation of ethylester 3a and silyl ether 3b'. Compounds 1 and 2 showed strong growth inhibition in MDA-MB-231 breast cancer cells and improved metabolic stability in comparison to A. Compound 2 exhibited significant in vivo PD effects to increase tumor necrosis factor-alpha mRNA in a dose dependent manner.

Abstract
In order to determine a suitable condition for osteoblasts cryopreservation, murine osteoblasts were freezed by programmed freezer with a magnetic field (CAS freezer). After 7 days cryopreservation at -150°, the number of survival cells immediately after thawing and the growth rate of cultured cells for 48 hours were examined. Gene and protein expression of alkaline phosphatase (ALP), osteopontin (OPN) and bone sialoprotein (BSP) were compared between cryopreserved and non-cryopreserved groups. As a result, a plunging temperature of -30°, a hold-time at -5° for 15 minutes and a 0.1 mT of magnetic field led to the largest survival and growth rate. Moreover, there was no significant difference in ALP, OPN and BSP mRNA and protein expression between cryopreserved and control groups. From these results, it was suggested that the CAS freezer is available for osteoblast cryopreservation and bone tissue banking can be established in the future.

Abstract
We have previously reported on study results showing that certain types of coffee have the activity to enhance fibrinolysis. This report covers the activity of 10 types of hot water extracts of coffee on human tissue-type plasminogen activator producing cells. Particularly strong activity (29-35 times the control amount) was observed for Blue Mountain, Yunnan and Kilimanjaro beans. It was found that the hot water extracts have anti-thrombin activity, and that coffee components have anti-platelet aggregation activity, although weak. It was revealed that there is no activity affecting tissue-type plasminogen activator producing cells in the coffee components chlorogenic acid, caffeine, quinic acid, trigonelline hydrochloride, 5-(hydroxymethyl)-2-furfuryl and caffeic acid. It was also revealed that there is activity in fractions with a molecular weight of 10,000 or less. This could also be inferred from the fact that oral administration of such fractions of coffee to human subjects resulted in a shortening of their plasma ELT (p<0.05).

Abstract
Nattokinase is a single polypeptide chain composed of 275 amino acids (molecular weight 27,724) which displays strong fibrinolytic activity. Moreover, it can activate other fibrinolytic enzymes such as pro-urokinase and tissue plasminogen activator. In the present study, native nattokinase from Bacillus subtilis natto was purified using gel-filtration chromatography and crystallized to give needle-like crystals which could be used for X-ray diffraction experiments. The crystals belonged to space group C2, with unit-cell parameters a=74.3, b=49.9, c=56.3 Å, β=95.2°. Diffraction images were processed to a resolution of 1.74 Å with an Rmerge of 5.2% (15.3% in the highest resolution shell) and a completeness of 69.8% (30.0% in the highest resolution shell). This study reports the first X-ray diffraction analysis of nattokinase.

Abstract
Soybean isoflavones of genistein and biochanin A, its analogue, promote the activity for generating tissue-plasminogen activator (tPA) from human cervical cancer cells (HeLa S3) and human umbilical vein endothelial cells (HUVEC). At a concentration of 50 microM, each of 14 types of isoflavones were added to HeLa culture solution and incubated. After 24 h, the culture solution was replaced, and then incubated for another 24 h. When fibrinolytic activity was checked in the resulting culture solution using the fibrin plate method, substantial fibrinolytic activity was confirmed for two types of isoflavones. Genistein showed the highest level of fibrinolytic activity at 12.4 times the control, and for biochanin A, an analogue of genistein, the level was 3.5 times the control. Checking fibrinolytic activity and molecular weight of the protein bands separated by zymography, a rise in the protein band concentration in proportion to the concentration of the reagents added was confirmed for the protein band with activity in the same position as the standard reference tPA, which has a molecular weight of about 68 kDa. ELISA also demonstrated that the concentration of tPA in the culture solution was higher than that of plasminogen activator-1. Fibrinolytic activity of HUVEC incubated with 25 microM of biochanin A was much higher than that of the control, which suggests that these soybean isoflavones could have beneficial effects on blood circulation in vivo.

Abstract
BACKGROUND Myotonic dystrophy type 1 (DM1) is a multisystemic disorder caused by a CTG repeat expansion in the DMPK gene. Aberrant messenger RNA (mRNA) splicing of several genes has been reported to explain some of the symptoms in DM1, but the cause of muscle wasting is still unknown. By contrast, many forms of muscular dystrophy are caused by abnormalities of the dystrophin-glycoprotein complex (DGC). alpha-Dystrobrevin is a key component of the DGC in striated muscle and plays important roles in maturation and signal transduction by interacting with alpha-syntrophin. The goal of this study was to investigate alternative splicing of alpha-dystrobrevin in DM1 and examine alpha-syntrophin binding of different alpha-dystrobrevin splice isoforms. METHODS Splicing patterns of alpha-dystrobrevin in DM1 muscle were studied by reverse-transcriptase PCR. Expression of the variant splice isoform was examined by immunoblotting and immunohistochemistry. Alternatively spliced isoforms were expressed in cultured cells to investigate interaction with alpha-syntrophin. alpha-Syntrophin expression was examined by immunoblotting. RESULTS alpha-Dystrobrevin mRNA including exons 11A and 12 was increased in both skeletal and cardiac muscle of DM1 patients. The aberrantly spliced alpha-dystrobrevin isoform was localized to the sarcolemma, and showed increased binding with alpha-syntrophin. Furthermore, levels of alpha-syntrophin associated with the DGC were increased in DM1 muscle. CONCLUSION Alternative splicing of alpha-dystrobrevin is dysregulated in myotonic dystrophy type 1 (DM1) muscle, resulting in changes in alpha-syntrophin binding. These results raise the possibility that effects on alpha-dystrobrevin splicing may influence signaling in DM1 muscle cells.
