    ABSTRACT: Historical research may be able to contribute to the exploration of traditional knowledge about medicinal plants and promising attempts have been made investigating Byzantine texts, Early Modern herbals, and writings of Christian missionaries. In this pilot study it should be explored if publications, travel reports, diaries or correspondence of the botanical explorers of the 19th and early 20th centuries may serve a source of ethnopharmacological information as well and may be able to guide modern phytopharmacological research. Writings of Berthold Seemann (1825-1871), a German investigator exploring the botany of Middle America, the Fiji islands and other regions, are investigated as a first example. It could be shown that Seemann’s heritage mainly kept at Kew Garden Archives, does contain ethnopharmacological information which in part has already been confirmed by recent study results indicating some reliability of his observations. However, there are also reports about traditional medicinal plants scarcely investigated so far, including Schultesia stenophylla Mart. (syn. S. guainensis (Aubl.) Malme), Trixis inula Crantz,Waltheria glomerata Presl., Gonophlebium attenuatum (Humb. & Bonpl. Es Willd) C. Presl., or Pseudoelephantopus spicatus (Juss ex Aubl.) C.F. Baker. It is suggested to further explore their potential as medicinal plants. In general, as Seemann’s example has shown, publications and correspondence of botanical explorers of the past seem to be a valuable and hitherto almost neglected source of information to be considered in further historical and ethnopharmacological research.

    ABSTRACT: There is - apart from clinical trials - an ongoing discussion on how to demonstrate therapeutic equivalence for locally applied and locally acting products in the gastrointestinal tract. Possibly, among other alternatives, in vitro drug release models could be considered surrogates of drug release and availability at the site of action. However, to date the conditions in which in vitro models provide valid surrogates of in vivo release and availability at the site of action would have to be defined. To demonstrate the potential applicability of in vitro test methods for screening therapeutic equivalence of locally applied and locally acting gastrointestinal products and also to get an idea of which would be the right dosage form for an individual patient a series of in vitro studies was performed comparing a variety of in vitro release methods ranging from pharmacopoeial methods to “patient-specific” release methods in examining drug release of four mesalazine tablet formulations intended for local drug delivery in the gastrointestinal tract. Results from this study indicated that pharmacopoeial quality control methods are hardly applicable to predict the therapeutic equivalence of such products. Moreover, comparison of the results obtained with the different in vitro methods reveal that a prediction of the therapeutic equivalence for locally acting products in the gastrointestinal tract is unlikely based on release profiles obtained in a single drug release experiment. However, results from the study also indicated that a set of individualized biorelevant in vitro test scenarios might be very useful for both demonstrating therapeutic equivalence and selecting the appropriate drug product for a particular patient.

    ABSTRACT: A stability-indicating RP-LC method for the determination of prasugrel in tablets was developed and validated. Stress testing of prasugrel was carried out in accordance with ICH guidelines, where the drug was submitted to acidic and basic hydrolysis, oxidative, thermal and photolytic conditions. Prasugrel was unstable under all the conditions and the degradations products were analyzed by HPLC-UV. Furthermore, two main degradation products found under alkaline and thermal conditions were investigated by LC-MS. Based on the fragmentation patterns, two products resulted from hydrolysis of the acetate ester moiety of prasugrel were observed. Due the chemical equilibrium, tautomerism occurs between the ketone and alcohol functions justifying the similar molecular weight and fragment pattern obtained in degradation products analysis. Successful separation was achieved on a RP-18 octadecyl silane column using acetonitrile and triethylamine 0.5% mixture (50:50, v/v) as the mobile phase at 25 °C. The flow rate was 1.0 mL/min and the detector wavelength was 263 nm. The method proposed in this work was successfully applied to quality control of prasugrel and contribute to stability assessment of pharmaceutical products containing this drug.

    ABSTRACT: Five indolin-2-one derivatives bearing piperazinylbutyl side chains attached to the amide nitrogen were synthesized from 2-indolinone. 1-(4-Bromobutyl)-indolin-2-one was reacted with 1-piperazinecarboxaldehyde to form 1-(4-(4-formyl-1-piperazinyl)butyl)indolin-2-one (2). In the presence of H2SO4, the aldehyde moiety was removed from 1-(4-(4-formyl-1-piperazinyl)butyl)indolin-2-one and then 1-(4-(1-piperazinyl)butyl)indolin-2-one (3) was obtained, this compound was reacted with benzaldehyde derivatives to give the target compounds 4 a-e by N-alkylation reaction. The structures of the intermediates and the target compounds were characterized by 1H NMR, ESI-MS spectra and elemental analyses. In vitro receptor binding assays at D2, D3, D4 receptor subtypes of the target compounds were performed and the five compounds showed selectivity towards D2-like receptors. Among them, 1-(4-(4-(4-hydroxybenzyl)-1-piperazinyl)butyl) indolin-2-one (4c) exhibited a remarkable affinity and selectivity to D4 receptor with K i value of 0.5 nM. The results indicated that 1-(4-(4-(4-hydroxybenzyl)-1-piperazinyl)butyl)indolin-2-one might be a potential dopamine D4 receptor ligand.

    ABSTRACT: Medicinal products obtained by recombinant DNA technology are complex molecules and demonstrate a high degree of molecular heterogeneity. Charge heterogeneity and isoform pattern of this class of medicines, are parameters important for their quality, safety, and efficacy. In this study we report the application of two-dimensional gel electrophoresis (2-D electrophoresis) for the quality assessment, identification, charge heterogeneity and isoform pattern study of recombinant protein, CTLA4-Ig (abatacept), which has been selected as an example of the drug class, known as Fc-fusion proteins. In order to achieve an efficient separation of this complex analyte,2-D electrophoresis was optimized employing different experimental conditions regarding the selection of an immobilized pH gradient (IPG), sample pretreatment, presentation and detection procedure. Experimental datadocumented that 2-D electrophoresis is a suitable method for the assessment of identity, purity, structural integrity, isoform pattern and to monitor charge heterogeneity and post-translational glycosylation of the Fc-fusion protein, abatacept.

    ABSTRACT: Propofol (2,6-diisopropylphenol) is a short-acting anesthetic commonly used in clinical practice, and is rapidly metabolized into glucuronide by UDP-glucuronosyltransferase (UGT). In the present study, propofol glucuronidation was examined in the liver microsomes of male and female humans, monkeys, rats, and mice. The kinetics of propofol glucuronidation by liver microsomes fit the substrate inhibition model for humans and mice, the Hill model for monkeys, and the isoenzyme (biphasic) model for rats. The K m, V max, and CL int values of human liver microsomes were 50 μM, 5.6 nmol/min/mg protein, and 110 μL/min/mg protein, respectively, for males, and 46 μM, 6.0 nmol/min/mg protein, and 130 μL/min/mg protein, respectively, for females. The rank order of the CL int or CL max (in vitro clearance) values of liver microsomes was mice » humans > monkeys > rats (high-affinity phase) » rats (low-affinity phase) in both males and females. Although no significant sex differences were observed in the values of kinetic parameters in any animal species, the in vitro clearance values of liver microsomes were males females in monkeys, rats (high-affinity phase), and mice. These results demonstrated that the kinetic profile of propofol glucuronidation by liver microsomes markedly differed among humans, monkeys, rats, and mice, and suggest that species and sex differences exist in the roles of UGT isoform(s), including UGT1A9, involved in its metabolism.

    ABSTRACT: It has been reported that the improvement of activities of daily living (ADL) by rehabilitation affects glycemic control. However, there are no reports about antidiabetes drugs as factors affecting the outcomes of rehabilitation. Therefore, we investigated the effects of antidiabetes drugs on functional independence measure (FIM) [total (T), motor (M), and cognition (C) items] in stroke patients with diabetes who were discharged from the subacute rehabilitation ward. We chose the frequently used antidiabetes drugs [sulfonylurea (SU), dipeptidyl peptidase-IV inhibitors (DPP-IVIs), and α-glycosidase inhibitors (α-GIs)] as the basis for categorizing the patients. We compared the patients' background features and laboratory data among the three groups. As a result, when SU was used in stroke patients with diabetes, it is difficult to obtain significant FIM-M gain, FIM-C gain, FIM-M efficiency, and FIM-C efficiency compared with α-GIs. As a reason for this, we hypothesize the possibility of the involvement of insulin resistance. Therefore, we consider that insulin resistance should be determined early and that it is important to reduce insulin resistance comprehensively by involving experts.

    ABSTRACT: The integrated in vitro - in silico - in vivo approach has emerged into a biopharmaceutical toolkit that could accelerate drug development and improve drug product clinical performance in patients. In the present study, the influence of physiologically based media and dynamic dissolution testing on drug release from two metformin hydrochloride immediate release products with proven bioequivalence was tested. Metformin-specific physiologically based pharmacokinetic (PBPK) model was developed based on a range of literature or in silico predicted data using gastrointestinal simulation technology implemented in the Simcyp® software package. Various approaches were employed in order to estimate the human effective permeability which was used as input for metformin plasma profile simulation. Influence of the rate and extent of metformin dissolution on drug absorption was evaluated. Both convolution and deconvolution approaches were used in order to establish a correlation between the in vitro and in vivo data. The results obtained indicate that physiologically based dissolution media and glass bead dissolution device exhibit certain advantages over the compendial dissolution apparatus and simple buffers which tended to be over-discriminative. Gastrointestinal simulation technology implemented in the Simcyp® Simulator was successfully used in developing drug-specific PBPK model for metformin. Simulations indicate that in vitro dissolution kinetics has no significant effect on metformin absorption, if more than 65% of drug is released in 1 hour. Level A in vitro-in vivo correlation was obtained using both convolution and deconvolution approaches.

    ABSTRACT: The study investigates whether combination therapy of sildenafil with imatinib at a low dose (20 mg/kg) further ameliorates pulmonary hypertension (PH) in rats. The effects on right ventricle pressure (RVP), and right ventricle hypertrophy (RVH) were assessed in experimental monocrotaline (MCT)-induced pulmonary hypertension. Combined therapy reversed the MCT-induced increase in RVP more than each drug alone and decreased RV hypertrophy (RV/LV + S ratio), significantly. Such additive effects toward improvement of PH may result from both pharmacodynamic and pharmacokinetic drug-drug interactions, however, further studies are required to assess its mechanistic background.

    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: Human choriocarcinoma has been used as a model to study trophoblast transcellular drug transport in the placenta. Previous models had limitations regarding low molecular weight drug transport through the intracellular gap junction. The purpose of this study was to evaluate placental carrier-mediated transport across a differentiating JEG-3 choriocarcinoma cell (DJEGs) layer model in which the intracellular gap junction was restricted. Cimetidine is the substrate of an efflux transporter, breast cancer resistance protein (BCRP). BCRP highly expressed in the placenta, and its function in the DJEGs model was investigated. In addition, the placental drug transport of another efflux transporter, multidrug resistance-associated proteins (MRPs), and an influx transporter, monocarboxylate transporter (MCT), were examined with various substrates. Cimetidine permeated from the fetal side to the maternal side at significantly high levels and saturated in a dose-dependent manner. The permeability coefficient of a MRP substrate, fluorescein, across the DJEGs model was significantly increased by inhibiting MRP function with probenecid. On the other hand, permeation in the influx direction to the fetal side with a substrate of MCT, valproic acid, had a gentle dose-dependent saturation. These findings suggest that the DJEGs model could be used to evaluate transcellular placental drug transport mediated by major placental transporters.

    ABSTRACT: Adverse drug reactions (ADR) and drug ineffectiveness are the common in clinical practice. Recent studies have indicated their strong connection to the genetic feature of patients. To further illustrate this relationship, the discipline of Pharmacogenomics (PGx) was born. At present, in vitro cell models and in vivo transgenic animal models have a large potential to study the influence of human genetic mutations on drug response. Moreover, PGx guided clinical trials also provide benefits to drug development. With the drug targets introduced by PGx, great success has been achieved in targeted therapy (eg. gefitinib, cetuximab and ado-trastuzumab). Although the progress on PGx research is fascinating, the translation of PGx into drug development is unsatisfactory. To improve this situation, a rounded system that includes individuals, medical staff, academics associations, Government and Pharmaceutics-Biotechnology Industry should be established, as well as a connected pipeline consisting of policy guidance, PGx research, genotyping technology, preclinical and clinical studies.

    ABSTRACT: OATP1B1 is an influx transporter known to mediate the uptake of various endogenous compounds and xenobiotics. Several sequence variations have been discovered in the SLCO1B1 gene encoding OATP1B1. The aim of this study was to investigate the effects of SLCO1B1 polymorphisms on the pharmacokinetics of atorvastatin in healthy volunteers of Macedonian origin. Twenty three participants, genotyped for SLCO1B1 c.388A > G, c.521T > C, c.571T > C, c.597C > T, c.1086C > T, c.1463G > C and c.*439T > G polymorphisms using TaqMan allelic discrimination assay, ingested a single 80 mg dose of atorvastatin. The plasma concentrations of atorvastatin were measured for 48 h using Tandem Liquid Chromatography-Mass Spectrometry, LC-MS-MS, and the peak plasma concentration (Cmax), time to peak plasma concentration (Tmax), elimination half-life (t1/2), constant rate of elimination (kel), mean residence time (MRT, expo), volume of distribution (Vd/kg), clearance (CL/kg), area under curve AUC0-48h and AUC0-∞ were determined. Our data confirmed that the SLCO1B1 gene is highly polymorphic, with a frequency of the c.521T > C single-nucleotide polymorphism (SNP) being the lowest (app. 15%) and of all other SNPs alleles above 40%. Exceptions were c.1463G > C and c.1086C > T SNPs for which variant alleles were not identified. The strongest correlation was observed between the c.521T > C and c.571T > C SNPs pair. The haplotype analysis revealed 10 different haplotypes, with *1J/*1K/*1L being the dominant, with a frequency of app. 40%. The haplotype *15/*16/*17, containing both variant alleles of the functionally most distinguished SNPs, c.388A > G and c.521T > C, occurred with a frequency of 13%. However, *15/*16/*17 homozygotes were not identified in the study group. In this study, no significant differences in the kel, t1/2, Cmax, Tmax, AUC0-48h, AUC0-∞, MRT expo, Vd and CL between the carriers of different c.388A > G, c.597C > T and c.*439T > G genotypes were observed. Subject with a variant allele C in the c.521T > C SNP, c.521CC genotype, had markedly higher values for Cmax and AUC0-48h, 140% and 67%, respectively, in comparison with the carriers of the c.521TT genotype. Also, the carriers of the variant allele C at c.571T > C SNP, c.571 CC genotype, had 55% and 43% lower mean Cmax and AUC0-48h in comparison with the carrier of c.571TT. These differences lacked statistical significance due to the size of the sample. In addition, no significant differences in the pharmacokinetic parameters of atorvastatin between the *15/*16/*17 heterozygotes and *15/*16/*17 non-carriers were observed. In conclusion, this extensive analysis of the effect of SLCO1B1 polymorphisms on the pharmacokinetic profile of atorvastatin showed that c.521T > C and c.571T > C SNPs may affect the inter-individual response to atorvastatin. Additional studies, with a large sample size, are needed to confirm this finding.

    ABSTRACT: Ampelopsin (AMP), a novel flavonoid, has been shown to effectively inhibit the proliferation and induce apoptosis of some prostate cancer and breast cancer cell lines. Whether AMP has chemopreventive effects on the cell growth and apoptosis of human osteosarcoma MG-63 cells remains unknown. In the present study, MG-63 cells were exposed to different concentrations (0, 25, 50, 75, 100 μmol/L) of AMP for 24, 48, 72 and 96 h and then the cell viability was measured by CCK-8 assay. The AMP-induced apoptotic cells were identified by Hochest33258 staining and quantified by Annexin V-FITC/PI double staining using flowcytometry (FCM). The effect of ampelopsin (AMP) on cell cycle was evaluated using PI staining with FCM. The protein levels of cyclin A, CDK2 and p21CIP1 were measured by Western blotting. The cell viability was reduced in a time- and dose-dependent manner after exposure to AMP at a range of 20-100 μmol/L. For the treatment of AMP, increases of apoptotic index and rate were observed in MG-63 cells. The AMP blocked cells in the G0/G1 phase of the cell cycle. Furthermore, AMP increased p21CIP1 expression but decreased cyclin A and CDK2 expression after AMP exposure. AMP inhibited cell growth and induced apoptosis and G0/G1 phase arrest in MG-63 cells in vitro, with the potential mechanism of the negative regulation of cell cycle-related protein.

    ABSTRACT: The electrochemical behavior of the azole antifungal agents itraconazole, posaconazole and ketoconazole has been investigated at a glassy carbon working electrode using cyclic voltammetry. All measurements were carried out in a supporting electrolyte solution consisting of a 1:1 (v/v) mixture of 0.1 mol L-1 sodium phosphate buffers and acetonitrile at various substance concentrations and pH values. An amperometric cell with a three electrode system consisting of a working electrode, a palladium reference electrode and a platinum disk as the auxiliary electrode was used in all experiments. All azoles showed a similar electrochemical behavior involving two reactions. An irreversible oxidation occurred at potentials of about 0.5 V. A reduction peak was detected at potentials between –0.28 V and –0.14 V with an associated oxidation peak, which was observed in consecutive repeated measurements at potentials between –0.03 and 0.28 V. The reduction and corresponding oxidation can be regarded as a quasi-reversible process. The proposed reaction mechanisms are an irreversible oxidation of the piperazine moiety at higher potentials as well as a reduction at lower potentials of the carbonyl group of the triazolone moiety in the case of itraconazole and posaconazole or a reduction of the methoxy group of ketoconazole.

    ABSTRACT: The two herbs Ligusticum chuanxiong (LC) Hort. (Umbelliferae) and Gastrodia elata (GE) Blume (Orchidaceae), are widely used in the clinic for the treatment of migraine. This article aims to understand the effects of LC and GE on blood-brain barrier (BBB) permeability in migraine rats. Serotonin, excitatory amino acids (EAAs) and matrix metalloproteinase-9 (MMP-9) were determined at different sampling times to assess BBB disruption during a migraine attack. BBB permeability was examined by fluorescence imaging and Evans blue dye (EBD) extravasation. The results showed that the expression of serotonin in migraine rat brain was enhanced from 30 min to 120 min and glutamate (Glu) was suppressed from 30 min to 60 min in LC-GE group compared with the model group (p < 0.05 or 0.01), while the MMP-9 levels in migraine rat blood was increased at 30 min as well as decreased at 120 min in LC-GE group compared with the model group (p < 0.05 or 0.01). EBD levels in rat brain were significantly lower at 30-60 min and 120-150 min in LC-GE group than that of the model group (p < 0.05 or 0.01). Our findings demonstrated that LC and GE might decrease BBB permeability and maintain its integrity through regulating serotonin, EAAs and MMP-9 in migraine rats.

    ABSTRACT: Ginsenosides, also known as ginseng saponins, are responsible for most pharmacological effect of ginseng. Ginsenoside Rb1 (Rb1) exerts a variety of pharmacological properties, including anti-inflammatory, antistress, anti-aging and anti-neurodegenerative activities. The aim of the present work was to assess the skin anti-photoaging properties of Rb1in human dermal keratinocyte HaCaT cells. The anti-photoaging activity was evaluated by analyzing the levels of reactive oxygen species (ROS) and matrix metalloproteinases (MMPs) as well as cell viability for HaCaT cells under UV-B irradiation. Rb1 was able to suppress the ROS levels which were elevated under UV-B irradiation, and unable to influence cellular survival in UV-B-irradiated HaCaT cells. Rb1 diminished the enhancement of MMP-2 gelatinolytic activity in conditioned medium, which corresponded with the decreased MMP-2 protein levels in both conditioned medium and cellular lysate prepared from UV-B-irradiated HaCaT cultures. Rb1 could restore the total glutathione (GSH) and superoxide dismutase (SOD) activity diminished in UV-B-irradiated HaCaT cells. Ginsenoside Rb1 possesses skin anti-photoaging properties through scavenging ROS and decreasing MMP-2 levels possibly by enhancing antioxidant activity in keratinocytes under UV-B irradiation.
