Gifu Pharmaceutical University Pharmacy was established in front of Gifu University Hospital (GUH) as a pharmacy attached to the university, the first in Japan in 1998. When GUH moved in 2004, Gifu Pharmaceutical University Pharmacy was built in its current location. One of the priorities of the design of the new facility was easy access to those with disabilities. For example, ramps, wheelchair accessible restrooms, and handicap-friendly waiting-room chairs were installed. In cooperation with GUH, we introduced a two-dimensional bar code system for prescriptions. This promoted the efficiency of compounding medicines. In addition, starting in 2006, we introduced digital drug-history records at Gifu Pharmaceutical University Pharmacy. We also increased the staff of the affiliated pharmacy in 2006. We designed the system of the affiliated pharmacy for long-term pharmacy practice. Currently, we accept pharmacy students visiting pharmacy of early exposure and long-term pharmacy practice. Today, the pharmacy fills an average of 80 prescriptions a day, primarily from GUH. Our staff consists of six pharmacists, one full-time office manager, and three part-time office assistants. In keeping with our role as a community pharmacy, we hold regular lectures and an education forum for pharmacists. We also carry out clinical studies. © 2016 The Pharmaceutical Society of Japan.

Stilbenoids such as resveratrol (3,5,4′-trihydroxystilbene) have drawn much attention due to the diversity of structures and biological activities. These compounds are typically found as oligomers in a few plant families, such as Dipterocarpaceae, Vitaceae, Leguminosae, Cyperaceae, and Gnetaceae. The rich structural variation and multifunctional bioactivity make stilbenoid oligomers interesting targets for detailed phytochemical investigations. The oligomeric stilbenoids in Dipterocarpaceaeous plants have been my main focus of extensive structural investigation for the past decade. The tetramers of a resveratrol such as (-)-hopeaphenol, vaticanol B, and vaticanol C are widespread and present in large quantities in Dipterocarpaceaeous plants. These are of special interest due to the large number of stereoisomers resulting from many asymmetric carbons and the various frameworks when a resveratrol is homogeneously oligomerized. The structural variations in Vatica, Vateria, Upuna, Cotylelobium, Dipterocarpus, Shorea, and Hopea genera have been examined and about 120 new resveratrol oligomers isolated to date. A detailed structural determination based on comprehensive spectral study has solved the difficulties in elucidation caused by the complicated stereochemistry that comprises diastereomers, epimers, enantiomers, and rotamers. The isolates bear a structural variation of fused cyclic frameworks including heterocyclic and bicyclo ring systems, and have been developed as a chemical library for drug discovery and chemical biology probes for the first time. © 2011 The Pharmaceutical Society of Japan.

The feasibility of combining safe permeation enhancers in a mucoadhesive particulate system for the oral delivery of peptide drugs was investigated in this study. Polyelectrolyte complex nanoparticles (NPs) were prepared by ionic interaction of spermine (SPM) with polyacrylic acid (PAA) polymer. Cytotoxicity studies in Caco-2 monolayers revealed the safety of the delivery system in the concentration range used for permeation enhancement. The cellular transport of fluorescein isothiocyanate dextran (FD4) showed higher permeation enhancing profiles of SPM-PAA NPs, as compared to SPM solution or PAA NPs prepared by ionic gelation with MgCl 2 (Mg-PAA NPs). These permeation enhancing effects were associated with a reversible decrease in TEER values, suggesting a paracellular permeation pathway by reversible opening of the tight junctions. Furthermore, confocal microscopy results revealed strong association of the NPs prepared using fluorescence labeled PAA to Caco-2 cells. The permeation enhancing properties of SPM-PAA NPs were further evaluated in vivo after oral administration to rats, using FD4 and calcitonin as models of poorly permeating drugs. Confocal microscopy images of rats' small intestine confirmed previous findings in Caco-2 cells and revealed a strong and prolonged penetration of FD4 from the mucosal to the basolateral side of the intestinal wall. In addition, the proposed NPs were efficient in improving the oral absorption of calcitonin, as evidenced by the significant and prolonged reduction of the blood calcemia in rats. © 2010 Elsevier B.V.

Benzodiazepines are among the most frequently prescribed drugs due to their sedative, hypnotic, anxiolytic, muscle relaxant and antiepileptic properties. Because of the high consumption of benzodiazepines worldwide, this class of drugs and their metabolites are frequently present in both clinical and forensic cases. For these reasons, the analysis of benzodiazepines and their metabolites in biological fluids is of great interest to clinicians and forensic toxicologists. This paper reviews procedures for multi-analyte single-stage (LC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) using different mass analyzers for the screening, identification and/or quantification of drugs, poisons and/or their metabolites in blood, plasma, serum or urine published since 2001. Basic information about the biosamples assayed, work-up, LC column, mobile phase, ionization type, mass spectral detection mode, matrix effects and validation data for each procedure is summarized. The feasibility of using LC-MS(/MS) techniques to identify and quantify benzodiazepines and their metabolites is also discussed. © 2011 John Wiley & Sons, Ltd.

The androgen-independent LNCaP (AIDL) cell line was generated by maintaining prostate cancer LNCaP cells in a hormone-deprived medium. Notably, synthetic androgen R1881-related gene response is attenuated in AIDL cells as compared to the parental LNCaP cells. The aim of this study was to clarify the mechanisms underlying androgen sensitivity in AIDL cells. We first examined the expression of androgen receptor (AR) and its co-regulators. However, no significant difference in mRNA expression was found between LNCaP and AIDL cells. Remarkably, AR protein levels were induced by R1881 and DHT in LNCaP cells, but not in AIDL cells. We next performed the cDNA sequencing to detect mutations in the AR gene. The T877A mutation was detected both in LNCaP and AIDL cells. Furthermore, AIDL cells harbored a missense substitution (TGG → TGT) in the AR gene, which caused a point mutation at codon 741 (W741C). Double T877A and W741C AR mutants have been previously reported to exhibit reduced androgen sensitivity. Hence, the low-androgen-sensitive responses of AIDL cells may be explained, at least in part, by AR gene mutations.

A strategy involving palladium-catalysed aromatic C-H functionalisation/ intramolecular alkenylation provides a convenient and direct synthesis of 3-alkylideneoxindoles. In the presence of 5 mol% of PdCl2MeCN 2 and AgOCOCF3, a wide variety of N-cinnamoylanilines gave 3-alkylideneoxindoles in moderate to good yield. © The Royal Society of Chemistry.

Our previous study indicated that both 17β-estradiol (E2), known to be an endogenous estrogen, and bisphenol A (BPA), known to be a xenoestrogen, could positively influence the proliferation or differentiation of neural stem/progenitor cells (NS/PCs). The aim of the present study was to identify the signal transduction pathways for estrogenic activities promoting proliferation and differentiation of NS/PCs via well known nuclear estrogen receptors (ERs) or putative membrane-associated ERs. NS/PCs were cultured from the telencephalon of 15-day-old rat embryos. In order to confirm the involvement of nuclear ERs for estrogenic activities, their specific antagonist, ICI-182,780, was used. The presence of putative membrane-associated ER was functionally examined as to whether E2 can activate rapid intracellular signaling mechanism. In order to confirm the involvement of membrane-associated ERs for estrogenic activities, a cell-impermeable E2, bovine serum albumin-conjugated E2 (E2-BSA) was used. We showed that E2 could rapidly activate extracellular signal-regulated kinases 1/2 (ERK 1/2), which was not inhibited by ICI-182,780. ICI-182,780 abrogated the stimulatory effect of these estrogens (E2 and BPA) on the proliferation of NS/PCs, but not their effect on the differentiation of the NS/PCs into oligodendroglia. Furthermore, E2-BSA mimicked the activity of differentiation from NS/PCs into oligodendroglia, but not the activity of proliferation. Our study suggests that (1) the estrogen induced proliferation of NS/PCs is mediated via nuclear ERs; (2) the oligodendroglial generation from NS/PCs is likely to be stimulated via putative membrane-associated ERs.


Purpose The incidence of Alzheimer's disease (AD) has been steadily increasing worldwide. AD is a serious disease that has both societal and economic impacts. The greatest risk factor for AD is aging. Thus, because of the rapidly aging population in Japan, the development of new, effective drugs for AD is urgently needed. The goal of the present article was to analyze the status, clarify the problems, and discuss the scientific and political challenges of disease-modifying drug development for AD. Methods Public data, official documents, literature, and news releases were surveyed and discussed. Findings Compared with diabetes mellitus drugs, there is a lack of quantitative surrogate end points among AD drugs. Much AD drug development has focused on amyloid-β and its associated pathways; however, these drugs have not shown efficacy in Phase III clinical trials. Thus, the US Food and Drug Administration has appealed for a new draft industrial guidance for the development of AD drugs, including those for early-stage AD. In Japan, the Minister of Health, Labour and Welfare and the Pharmaceuticals and Medical Devices Agency have also taken action, including the publication of potential new guidelines for clinical evaluation and development of new AD therapeutics, including drugs. Moreover, scientific initiatives to develop novel AD drugs are ongoing. Implications The development of quantitative surrogate end points remains necessary to improve the development of AD drugs. Therefore, collaboration among industry, government, and academia should be encouraged. Following the principles of regulatory science, strategies to develop drugs for illnesses with unmet needs can be framed by investigating the effects of past, current, and future AD drug development initiatives. © 2015 Elsevier HS Journals, Inc.

Although labile iron plays critical roles in diverse biological processes in living cells, the physiological and pathophysiological functions of iron have not been sufficiently explored, partially due to a lack of methods for visualizing intracellular labile iron. In this edge article, we present a novel turn-on fluorescent probe (RhoNox-1) for the selective detection of Fe 2+ based on N-oxide chemistry. Spectroscopic studies combined with DFT calculations and electrochemical studies revealed that fluorescence quenching of RhoNox-1 occurred in physiological conditions, which was attributed to non-radiative deactivation of the excited state of tertiary amine N-oxide substituted xanthene involving a twisted internal charge transfer (TICT) process and partially due to photo-induced electron transfer (PET) from the N-oxide group. RhoNox-1 showed significant enhancement of the fluorescence signal in Fe2+-loaded cells via selective Fe2+-mediated deoxygenation of the N-oxide group and also successfully detected basal and endogenous labile Fe2+ in living cells. © 2013 The Royal Society of Chemistry.

Metallothionein (MT) is a small molecular and multi-functional protein containing four atoms of copper (Cu) and three atoms of zinc (Zn) per molecule. It was isolated from the horse kidney in 1957 and half a century has passed since then. Although MT was found to work as a modulator of Zn and induce anti-oxidant reaction, the precise functions and its functional mechanisms remain to be elucidated. Over the years, a new isoform of MT, MT-III (also called growth inhibitory factor (GIF)), has been found in the brain, which was markedly diminished in the brain of Alzheimer's disease (AD). Many new findings on MT have been discovered in neurodegenerative diseases other than AD such as amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), prion disease, brain trauma, brain ischemia, and psychiatric diseases. In ALS in particular, MTs were markedly diminished in the spinal cord of patients with ALS. Initially, MT, which easily binds to cadmium (Cd) and copper (Cu), was considered to be toxic to our bodies. Molecular biological technologies enabled the production of recombinant MT saturated with zinc (Zn). MT has a high potential for the treatment of neurodegenerative diseases such as ALS, AD, and PD owing to its various functions including anti-oxidant properties and modulators not only for Zn but for Cu in the extra- and intracellular spaces. On the other hand, there are still various problems on MT to be elucidated in detail, including their binding proteins and functional mechanisms. © 2013 Bentham Science Publishers.
