    ABSTRACT: Fifteen 2-substituted ethenesulfonic acid ester derivatives were designed, synthesized, and evaluated for the inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) and T-Cell protein tyrosine phosphatase (TCPTP). The structural activity relationship (SAR) of these compounds are discussed to clarify the impact of the linker and the optimized tail on the inhibitory activity of PTP1B and selectivity over TCPTP. Most of the compounds exhibit excellent inhibitory activities against PTP1B with IC50 values of 1.5-8.9�M. SAR analysis reveal that the substituents at the hydrophobic tail significantly alter the inhibitory activity against PTP1B and selectivity over TCPTP, e.g. compound 5d showed excellent inhibitory activity to PTP1B with IC50 = 7.8�M, and ∼6-fold selectivity over TCPTP. Combined with our previous findings, we confirm that the linker length and the substituted hydrophobic tail have decisive influence on the PTP1B inhibitory activity and selectivity.

    ABSTRACT: A capillary zone electrophoresis method was developed for the simultaneous determination of valsartan (VAL), amlodipine besylate (AML) and hydrochlorothiazide (HCZ) in their combined tablets. Separation was achieved on a fused silica capillary by applying a potential of 15 kV (positive polarity) and a running background electrolyte containing 40mM phosphate buffer at pH 7.5 with UV detection at 230 nm. The samples were injected hydrodynamically for 3 s at 0.5 psi and the temperature of the capillary cartridge was kept at 25 ◦C. Pyrazinoic acid was used as an internal standard. The method was validated according to ICH guidelines regarding specificity, linearity, limits of detection and quantitation, accuracy and precision, (Supplementary materials, Table S2). The method showed satisfactory linearity in the ranges of 10-200, 2-20 and 2-20 �g mL-1 with LODs of 1.82, 0.39, 0.65 �g mL-1 and LOQs of 5.51, 1.17, 1.96 �g mL-1 for VAL, AML and HCZ, respectively. The proposed method was successfully applied for the analysis of the studied drugs in their laboratory prepared mixtures and co-formulated tablets. The results were compared with reported methods and no significant differences were found. The proposed method can be used for quality control of the cited drugs in ordinary laboratories.

    ABSTRACT: We aimed to investigate whether a combination of resistance to arsenic trioxide (As2O3) and the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway inhibitor LY294002 can inhibit the proliferation of AML cells in the bone marrow microenvironment. Three AML cell lines were grown with HS-5 human bone marrow stromal cells in adherent co-cultures. The inhibitory effects of As2O3 alone or in combination with LY294002 on the proliferation of these co-cultured AML cells were observed. The PI3K/Akt signaling pathway was detected by Western Blot in co-cultured AML cells cultured alone or treated with As2O3 alone or in combination with LY294002. Our results demonstrate that AML cells adhered to stroma exhibited significantly reduced sensitivity to As2O3. The resistance can be partially abolished by inhibiting the PI3K/Akt pathway. The administration of As2O3 in combination with a PI3K/Akt signaling pathway inhibitor may be expected to become a new approach to the treatment of AML.

    ABSTRACT: This study was undertaken to identify new anti-diabetic substances, and we successfully identified the new potent anti-diabetic agent 2,5-dimethoxy(4-methoxyphenyl)benzamide (DMPB). The glucose uptake of C2C12 muscle cells more than doubled following treatment with 50 μM DMPB. This compound also enhanced the expressions of pAMPK, pACC, and pAKT, which are target proteins for glucose uptake improvement in C2C12 cells. Moreover, DMPB increased the transcriptional activity of the peroxisome proliferator-activated receptor in HEK 293 kidney cells. These results suggest that DMPB has potential as an anti-diabetic substance.

    ABSTRACT: The effects of some polymeric additives, i.e. corn starch (CS) and magnesium stearate (MS), on mechanical properties (tensile strength, modulus of elasticity, and elongation at break) and adhesive toughness of hydroxypropyl methylcellulose (HPMC) and ethylcellulose (EC) film coats were investigated. The free and in situ films containing 10 and 20% additives by weight of polymer were prepared by spray method. The mechanical properties of both HPMC and EC free films decreased as the concentration of additives was increased because of the lower stiffening effect brought about by hydrodynamic or reinforcing effect. However, adhesive toughness of in situ films was found to increase for HPMC whereas that of EC films decreased with the increasing concentration of polymeric additives. Such contradictory results between these two film forming polymers may be attributed to the net result of the opposite effects between interference of film-tablet interfacial bonds and the reduction of mechanical properties. The former seemed to be preferential in the case of EC films, while the latter predominated for HPMC films. Such conclusions were supported by the FTIR results, in which the polymer-additive interaction was found for EC. Increase in concentration of polymeric additives resulted in the decrease in mechanical properties of free films whereas the adhesive toughness of in situ films may be influenced by either the interference of film-tablet interfacial bonds or the significant reduction of mechanical properties.

    ABSTRACT: Long non-coding RNAs (lncRNAs) play important roles in various biological processes, such as transcriptional regulation, cell growth and tumorigenesis. However, little is known about the role of lncRNA HIF 1 alpha-antisense RNA 1 (HIF1a-AS1) in regulating the proliferation and apoptosis of vascular smooth muscle cells (VSMCs) and the expression of HIF1a-AS1 in serum of thoracoabdominal aortic aneurysm (TAAA) patients. The cell viability was detected by the CCK8 assay. The cell apoptosis was assessed by annexin V-PI double-labeling staining. Expression of genes and proteins were analyzed by real-time PCR and western blotting, respectively. Cells were transfected with siRNAs as a gene silencing method. In serum of TAAA patients, the expression of HIF1a-AS1 was significantly increased (superior to 6-fold) compared to the normal control. Moreover, Palmitic acid (PA) induced cell apoptosis in VSMCs in a time- and dose-dependent manner, and the proportion of the apoptotic cells had gained as compared to untreatment group. PA also induced up-regulation expression of HIF1a-AS1. We also found that transfection of cells with HIF1a-AS1 siRNA decreased the expression of caspase-3 and caspase-8 and increased the expression of Bcl2, and protected PA-induced cell apoptosis in VSMCs. HIF1a-AS1 was overexpressed in the TAAA and the interaction between HIF1a-AS1 and apoptotic proteins plays a key role in the proliferation and apoptosis of VSMCs in vitro, which may contribute to the pathogenesis of TAAA.

    ABSTRACT: A new cyclic bisdesmoside treterpene saponin, lobatoside N (1), together with four known triterpenoids, was isolated from the herb of Actinostemma lobatum Maxim. Structures were established by means of extensive spectral data analysis. Furthermore, the cytotoxic activities of the identified compounds were evaluated using HCT-116, HT-29, MCF-7 and A549 human cancer cell lines. As a result, compounds 1-5 showed significant cytotoxicities in a dose-dependent manner against the cell lines tested. Especially, compound 5 exhibited stronger activities, with IC50 value of 0.88 μM and 0.98 μM, than that of the positive control drug (Cis-platinum) against HT-29 and A549 cell lines.

    ABSTRACT: In the present work, we report efficient production of ginsenoside M1 (G-M1) from ginsenoside Rd (G-Rd) by snailase hydrolysis using response surface methodology (RSM). During investigation of the hydrolysis of ginsenoside Rd by various glycoside hydrolases, snailase showed a strong ability to transform G-Rd into G-M1 with 100% conversion. RSM was used to optimize the effects of the reaction temperature, enzyme load, and reaction time on the conversion process. Validation of the RSM model was verified by the good agreement between the experimental and the predicted values of G-M1 conversion yield. The optimum preparation conditions were as follows: temperature of 41.0°C; enzyme load of 17.5%; reaction time of 18 h. The determined method may be highly applicable for the enzymatic preparation of G-M1 for medicinal purpose. Furthermore, the effect of G-M1 on insulin secretion in MIN6 pancreatic β-cells was investigated.

    ABSTRACT: Actinidin (ATD) is a cysteine protease found in kiwifruit. It is used to tenderize meat and to enhance the digestion of proteins in the small intestine. However, ATD is unstable during freeze-drying, which alters its bioactivity. It is well known that sugars have the ability to protect proteins from the stress of freeze-drying. In this study, we investigated the protective effect of various saccharides on the stability of ATD during freeze-drying. The ATD activities of the samples containing γ-cyclodextrin (CyD) showed only a small decrease, and compared with trehalose and sucrose, γ-CyD was a more effective stabilizer for ATD. Secondary structural changes in freeze-dried ATD were observed by circular dichroism spectroscopy and compared with the changes in stabilized samples. There was a close relationship between the α-helix content and the stabilization. The sugars stabilized the protein by suppressing the changes in the α-helix. Fourier transform infrared spectroscopy measurement showed that the amide I band of ATD with γ-CyD was shifted to a lower wavenumber compared with other sugars. Therefore, stronger hydrogen bonds may be formed between ATD and γ-CyD than between ATD and other sugars. The suppression of changes in the protein secondary structure accompanying the formation of hydrogen bonding between the protein and the sugar also contributed to the protective effect of the sugars.

    ABSTRACT: Alternative splicing of the glucocorticoid receptor (GR) gene results in several GR isoforms, we examined their expression (GRα, GRβ, GRγ and GR-P) by real-time RT-PCR in glucocorticoid (GC) sensitive (CEM-C7), GC resistant (CEM-C1) cells and adult acute lymphoblastic leukemia (ALL) patients, to determine the association of GR isoform expression profiles and GC resistance in adult ALL patients. With GC treatment, GR levels in C1 cells showed no obvious changes. In C7 cells, the mRNA levels of GRα, GRβ and GRγ first increased and then decreased, whereas GR-P mRNA had a continued rising trend. C7 cells had a higher GRα/GRγ, lower GRα/GR-P and GRγ/GR-P ratios than C1 cells (P < 0.01). In adult ALL patients, GRγ mRNA varied in different ALL stages (complete remission CR 15.82 vs. relapsed 8.21 vs. initial 1.93 P < 0.05). It also did in the ratios between GR isoforms that GRα/GRγ and GRα/GR-P in initial patients were higher than relapsed and CR (P < 0.05), while GRγ/GR-P in CR was higher than initial and relapsed patients (P < 0.05). GR-P mRNA in T-ALL patients was much higher than that in B-ALL patients (P < 0.05). Peripheral blood hemoglobin (HB) was positively correlated with GRα mRNA and GR-P mRNA (P < 0.05), while white blood cells (WBC) negatively correlated with GRγ mRNA (P < 0.05). The present study demonstrates that GR autoinduction is more important to GC sensitivity than its basal level expression. GC sensitivity is also significantly correlated with GRα mRNA and mildly associated with GRβ mRNA expression. Both GRγ mRNA and the ratios between GR isoforms (GRα/GRγ, GRα/GR-P and GRγ/GR-P) are correlated with ALL stages. The changes of mRNA expression levels of GRα, GR-P and GRγ may provide valuable information for GC resistance. Peripheral blood HB and WBC affect GR isoform expression.

    ABSTRACT: In medicine today, future doctors are expected to ensure patient safety. Yet medical students often feel uncertain if they can meet these high expectations. This study aims to quantify the perceptions of medical students regarding the actual quality of their education in the fields of patient safety and, in particular, medication safety. A questionnaire was designed and distributed to about 100 upper-level medical students. The students had to respond to 12 questions regarding the following categories: 1) familiarity with patient safety and/or medication safety; 2) personal experience in high-risk clinical situations; and 3) perceived relevance of knowledge in the area of patient and medication Safety for clinical practice. Of the respondents 42.1% and 36.8% had delved into the topic patient safety and medication safety, respectively. In clinical practice 88.2% of respondents had experienced a high-risk situation for patients. Regarding patient safety and medication safety, respectively, 82.9% and 85.3% of the respondents found these topics to be particularly relevant to their clinical practice. This study has shown that there is a measurable discrepancy between the students' perceived quality of their medical education and their feelings that they are well prepared to cope with severe clinical challenges.

    ABSTRACT: The use of transmission near infrared spectroscopy (TNIRS) is of particular interest in the pharmaceutical industry. This is because TNIRS does not require sample preparation and can analyze several tens of tablet samples in an hour. It has the capability to measure all relevant information from a tablet, while still on the production line. However, TNIRS has a narrow spectrum range and overtone vibrations often overlap. To perform content uniformity testing in tablets by TNIRS, various properties in the tableting process need to be analyzed by a multivariate prediction model, such as a Partial Least Square Regression modeling. One issue is that typical approaches require several hundred reference samples to act as the basis of the method rather than a strategically designed method. This means that many batches are needed to prepare the reference samples; this requires time and is not cost effective. Our group investigated the concentration dependence of the calibration model with a strategic design. Consequently, we developed a more effective approach to the TNIRS calibration model than the existing methodology.

    ABSTRACT: Piroxicam is a potent, nonsteroidal, anti-inflammatory agent (NSAID) which also exhibits antipyretic activity. The antiviral effect of piroxicam against herpes simplex virus type 1 (HSV-1) was examined in vitro on RC-37 monkey kidney cells using a plaque reduction assay. Piroxicam was dissolved in ethanol or dimethylsulfoxide (DMSO) and the 50% inhibitory concentration (IC50) was determined at 4 μg/ml and 75 μg/ml, respectively. The IC50 for the standard antiherpetic drug acyclovir was determined at 1.6 μM. At non-cytotoxic concentrations of these piroxicam solutions, plaque formation was significantly reduced by 62.4% for ethanolic piroxicam and 72.8% for piroxicam in DMSO. The mode of antiviral action of these drugs was assessed by time-on-addition assays. No antiviral effect was observed when cells were incubated with piroxicam prior to infection with HSV-1 or when HSV-1 infected cells were treated with dissolved piroxicam. Herpesvirus infection was, however, significantly inhibited when HSV-1 was incubated with piroxicam prior to the infection of cells. These results indicate that piroxicam affected the virus before adsorption, but not after penetration into the host cell, suggesting that piroxicam exerts a direct antiviral effect on HSV-1. Free herpesvirus was sensitive to piroxicam in a concentration-dependent manner and the inhibition of HSV-1 appears to occur before entering the cell but not after penetration of the virus into the cell. Considering the lipophilic nature of piroxicam, which enables it to penetrate the skin, it might be suitable for topical treatment of herpetic infections.

    ABSTRACT: The objective of this study was to evaluate the standard voriconazole dosage regimen (maintenance dose was 200 mg bid orally) against Aspergillus infections in different CYP2C19 genotypes from a pharmacokinetic/pharmacodynamic (PK/PD) perspective. Monte Carlo simulation (MCS) was applied to simulate 5,000 patients by integrating published pharmacokinetic (PK) parameters, variability of PK parameters on CYP2C19 genotypes and microbiological data. The standard dosage regimen for poor metabolizers (PM) with Aspergillus infections was effective except A. versicolor, for heterozygous extensive metabolizers (HEM), Aspergillus fumigatus, A. terreus and A. nidulans infections could be treated effectively with the standard dosage regimen; for extensive metabolizers (EM), the standard voriconazole dosage regimen failed to achieve the best outcome for the six Aspergillus spp. Increasing dose (e.g. 300 mg bid) or even changing the antifungal drug was needed for EM and most HEM patients with Aspergillus infection. Instead of using a standard dosage regimen for all patients, the voriconazole dosage regimen needs to be optimized for patients with different CYP2C19 genotypes.

    ABSTRACT: Pathologically, loss of synapses and neurons, extracellular senile plaques and intracellular neurofibrillary tangles (NFTs) are observed in the brains of patients with Alzheimer's disease (AD). These features are associated with changes Aβ (amyloid β) 40, Aβ42, total tau and phosphorylated tau (p-tau), which are as definitely biomarkers for severe AD state. However, biomarkers for effectively diagnosing AD in the pre-clinical state for directing therapeutic strategies are lacking. Metabolic profiling as a powerful tool to identify new biomarkers is receiving increasing attention in AD. This review will focus on metabolomics-based detection of promising candidate biomarkers and pathways in AD to facilitate the discovery of new medicines and disease pathways.

    ABSTRACT: Epithelial-mesenchymal transition (EMT) is an early step in the process of tumor metastasis. It is well known that tumor microenvironment affects malignancy in various carcinomas; in particular, that hypoxia induces EMT. Deregulated notch signaling also contributes a lot to the development of EMT in lung cancer. In this study, we investigated the use of Notch-1-inhibiting compound as novel therapeutic candidates to regulate hypoxia-induced EMT in lung cancer cells. According to previous screening, nobiletin was selected as a Notch-1 inhibitor. Hypoxia-induced EMT was characteristic of increased N-cadherin & vimentin expressions and decreased E-cadherin expressions. Treatment with nobiletin notably attenuated hypoxia-induced EMT, invasion and migration in H1299 cells, accompanied with reduced Notch-1, Jagged1/2 expressions and its downstream genes Hey-1 and Hes-1. Nobiletin treatment also promoted tumorsuppressive miR-200b level. Moreover, notch-1 siRNA prevented hypoxia-mediated cell migration and decreased Twist1, Snail1, and ZEB1/2 expressions, which are key EMT markers. Re-expression of miR-200b blocked hypoxia-induced EMT and cell invasion. Our findings suggest that downregulation of Notch-1 and reexpression of miR-200b by nobiletin might be a novel remedy for the therapy of lung cancer.

    ABSTRACT: A series of novel ocotillol-type furoxan derivatives was synthesized by coupling various furoxans to 3-OH of 6-deoxy ocotillol, and their in vitro nitric oxide (NO) releasing capability was studied. The discharge of NO was examined after 30 min at two different concentrations, the results showed that all of the compounds tested could release NO in a dose-dependent manner. All of the synthesized compounds released similar amounts of NO at 100 μM, whereas at 500 μM these compounds showed more difference, in which compound II1, II3, II4, III2 displayed higher potency in releasing NO at this concentration. Analysis of the in vitro data showed that the derivatives bearing the same furoxan group on different ocotillol cores possessed various NO releasing capacity, suggesting that the structure of carrier of NO releasing groups may affect the NO release. Indeed, except compound II2, 24(S)-6-deoxy ocotillol derivatives from compound 6 with different furoxan substitutions at 3-OH and III2 displayed enhanced NO releasing capacity, compared to other compounds derived from compounds 5 and 9. The results illustrated that the functional group and the stereochemistry on the ocotillol structure may affect the NO release of furoxans.
