    Abstract CCR4 is a major trafficking receptor for T-helper (Th) 2 cells and Th17 cells and is considered as a potential therapeutic target for atopic dermatitis (AD). The CCR4 ligands CCL17 and CCL22 have been reported to be upregulated in the skin lesions of AD patients. Of note, thymic stromal lymphopoietin (TSLP), a master regulator of the Th2 immune response, promotes the expression of CCL17 and CCL22 in AD skin lesions. Here, we investigated the role of CCR4 in an AD mouse model induced by MC903, a TSLP inducer. Topical application of MC903 to ear skin increased the expression of not only TSLP but also CCL17, CCL22, the Th2 cytokine IL-4, and the Th17 cytokine IL-17A. Consistently, MC903 induced AD-like skin lesions as shown by increased epidermal thickness; increased infiltration of eosinophils, mast cells, type 2 innate lymphoid cells, Th2 cells, and Th17 cells; and elevated serum levels of total IgE. We also found increased expansion of Th2 cells and Th17 cells in the regional lymph nodes (LNs) of AD mice. Compound 22, a CCR4 inhibitor, ameliorated AD-like skin lesions with reduction of Th2 cells and Th17 cells in the skin lesions and regional LNs. We further confirmed that compound 22 diminished the expansion of Th2 cells and Th17 cells in the coculture of CD11c+ dendritic cells (DCs) and CD4+ T cells derived from the regional LNs of AD mice. Collectively, CCR4 antagonists may exhibit anti-allergic effects by inhibiting both the recruitment and expansion of Th2 cells and Th17 cells in AD.

    Cyanide is highly toxic to humans and the environment. It is very important to develop an on-site system for the quantitative analysis of cyanide with high sensitivity and reliability. In this study, we developed a cyanide detection system based on the reaction of vaporized cyanide on a glass-fiber filter soaked in a mixture of naphthalene-2,3-dicarboxaldehyde (NDA)-taurine-borate solution. Although the reaction product was stable for at least 3 days at room temperature, the reaction product on the strip was quickly quenched within a few minutes by direct irradiation with 405 nm light. To overcome this problem, we fabricated a simple device designed to detect the fluorescence intensity immediately after inserting a reaction strip into the device. The linearity of the calibration was obtained over a range of 1-100 µM of cyanide with good repeatability. The device is cost-effective (~ $300) and powered by batteries; therefore, it is suitable for the on-site determination of cyanide in crude samples.

    Atopic dermatitis is a chronic inflammatory skin disease involving T-helper (Th) 2 cells, eosinophils, and mast cells. Although CCR4 is a major chemokine receptor expressed on Th2 cells and regarded as a potential therapeutic target for allergic diseases, its role in atopic dermatitis remains unclear. Here, by using a hydrogel patch as a transcutaneous delivery device for ovalbumin (an antigen) and Staphylococcus aureus δ-toxin (a mast cell activator), we efficiently induced acute atopic dermatitis-like skin lesions in BALB/c mice, a strain prone to Th2 responses, which were characterized by increased numbers of eosinophils, mast cells, and CCR4-expressing Th2 cells in the skin lesions; elevated levels of total and ovalbumin-specific IgE in the sera; and increased expression of IL-4, IL-17A, IL-22, CCL17, CCL22, and CCR4 in the skin lesions. Of note, the same model was less efficient in C57BL/6 mice, a strain prone to Th1 responses. Using this atopic dermatitis model in BALB/c mice, we demonstrated that CCR4-deficiency or a CCR4 antagonist ameliorated the allergic responses. Collectively, these results demonstrate that CCR4 plays a pivotal role in skin allergic inflammation of BALB/c mice by recruiting CCR4-expressing Th2 cells and Th17 cells.

    Hydroxychavicol (HC), which is obtained from the leaves of Piper betle LINN. (Piperaceae), inhibits xanthine oxidase (XO) with an IC50 value of 16.7 µM, making it more potent than the clinically used allopurinol (IC50=30.7 µM). Herein, a structure-activity relationship analysis of the polar part analogs of HC was conducted and an inhibitor was discovered with a potency 13 times that of HC. Kinetic studies have revealed that HC and its active analog inhibit XO in an uncompetitive manner. The binding structure prediction of these inhibitor molecules to the XO complex with xanthine suggested that both compounds (HC and its analog) could simultaneously form hydrogen bonds with xanthine and XO.

    CCR4 is a major chemokine receptor expressed by Treg cells that downregulate immune responses. Here, we investigated the role of CCR4-mediated Treg cell recruitment in antigen-specific immune responses. CCR4-deficient mice immunized intramuscularly with ovalbumin (OVA) showed enhanced OVA-specific IgG responses. Furthermore, intramuscular administration of OVA induced the expression of MDC/CCL22, a ligand for CCR4, in macrophages of the muscle tissues, and enhanced the recruitment of CCR4+ Treg cells in wild-type mice, whereas this recruitment of Treg cells was severely impaired in CCR4-deficient mice. Furthermore, OVA-loaded dendritic cells (DCs) derived from the muscle injection site of CCR4-deficient mice had an upregulated expression of the DC activation marker CD40 and 86, and the lymphoid organ homing receptor CCR7 resulting in an increased number of migratory DCs in the regional lymph node. Compound 22, a CCR4 antagonist, also inhibited the recruitment of Treg cells to the muscle tissue, and further enhanced DC activation and homing to the regional lymph node. Consequently, Compound 22 enhanced OVA-specific IgG responses, and the expression levels of IL-4 and IFN-γ in CD4+ T cells and the levels of IFN-γ in CD8+ T cells. Finally, intramuscular administration of OVA and Compound 22 significantly inhibited the growth of OVA-expressing tumors. Collectively, CCR4 plays a pivotal role in Treg cell recruitment to the muscle tissue, and intramuscular administration of CCR4 antagonists may be a promising approach for enhancing vaccine efficacy.

    ObjectivesTo avoid the chelate formation between levofloxacin (LVFX) and aluminium hydroxide in gastrointestinal tract, an ethoxycarbonyl 1-ethyl hemiacetal ester of levofloxacin (LVFX-EHE) was synthesised as a prodrug. MethodsThe effects of aluminium hydroxide on the bioavailability of LVFX following oral administration of LVFX-EHE were investigated in rats. Furthermore, the effects of aluminium hydroxide on small intestinal absorption of LVFX and LVFX-EHE when subjected to a hydrolysis experiment using in situ everted gut sac were investigated, and the minimal inhibitory concentrations (MICs) of LVFX and LVFX-EHE for various intestinal bacteria were measured. Key findingsWhen LVFX-EHE was co-administered with and without aluminium hydroxide, the AUC(0-4 h) values of LVFX hydrolysed from LVFX-EHE were similar to that of LVFX alone. In everted gut sac experiments, LVFX-EHE was efficiently absorbed even in the presence of aluminium ions after 1 h of incubation, whereas the absorption of LVFX decreased significantly in the presence of aluminium ions. MIC values of LVFX-EHE were far higher than LVFX. ConclusionsThis study suggests the benefit of ethoxycarbonyl 1-ethyl hemiacetal esterification of the carboxyl group of new quinolone as a prodrug which is able to avoid chelate formation.

    CCR4 is a major chemokine receptor expressed by Treg cells and Th17 cells. While Treg cells are known to suppress antitumor immunity, Th17 cells have recently been shown to enhance the induction of antitumor cytotoxic T lymphocytes. Here, CCR4-deficient mice displayed enhanced tumor growth upon intradermal inoculation of B16-F10 melanoma cells. In CCR4-deficient mice, while IFN-γ+CD8+ effector T cells were decreased in tumor sites, IFN-γ+CD8+ T cells and Th17 cells were decreased in regional lymph nodes. In wild-type mice, CD4+IL-17A+ cells, which were identified as CCR4+CD44+ memory Th17, were found to be clustered around dendritic cells expressing MDC/CCL22, a ligand for CCR4, in regional lymph nodes. Compound 22, a CCR4 antagonist, also enhanced tumor growth and decreased Th17 cells in regional lymph nodes in tumor-bearing mice treated with Dacarbazine. In contrast, CCR6 deficiency did not affect the tumor growth and the numbers of Th17 cells in regional lymph nodes. These findings indicate that CCR4 is critically involved in regional lymph node DC-Th17 cell interactions that are necessary for Th17 cell-mediated induction of antitumor CD8+ effector T cells in mice bearing B16 melanoma.

    Novel protein kinase CK2 inhibitors were identified using the solvent dipole ordering virtual screening method. A total of 26 compounds categorized in 15 distinct scaffold classes inhibited greater than 50% of enzyme activity at 50 mu M, and eight exhibited IC50 values less than 10 mu M. Most of the identified compounds are lead-like and dissimilar to known inhibitors. The crystal structures of two of the CK2 complexes revealed the high accuracy of the predicted binding modes.

    Esterification of carboxylic acids with alkyl halides using electroreduction has been investigated. The reaction of carboxylic acids, such as benzoic acid, 3-phenylpropanoic acid, nonanoic acid, cinnamic acid, and 1-naphthoic acid, under electrochemical reduction conditions followed by the addition of alkyl halides afforded the corresponding esters in moderate to good yields. The reactions proceeded via the S(N)2 mechanism of the alkyl halide, with the carboxylate ion bearing the ammonium ion as the counter cation, which was generated and accumulated from the carboxylic acid. The generation of the carboxylate ion intermediate is essential, and it appears to have high reactivity because the counter cation of the carboxylate ion intermediate is an ammonium ion.

    In this work, quaternary ammonium group-modified celluloses (QCs) were homogeneously synthesized by reacting cellulose with 3-chloro-2-hydroxypropyltrimethylammonium chloride in NaOH/urea solutions. The structure and solution properties of the QCs were characterized by elemental analysis, FT/IR, 1H-NMR, and size exclusion chromatography. The results show that water-soluble QCs, with degree of substitution values, defined as the substitution of free hydroxyl groups of cellulose, 0.49– 0.72 and molecular weight 21–66 kDa could be obtained by optimizing the reaction time. The synthesized QCs were tested for protein separation as physically adsorbed coatings in capillary electrophoresis. Among the derivatives studied, quaternary ammonium cellulose showed rapid electroosmotic mobility and effective suppression of protein adsorption. The EOF can be manipulated for various applications by using QCs with different molecular weight. Because the reversed EOF can be obtained over a broad pH range, it is possible to separate basic, neutral, and acidic proteins under physiological conditions. Eight proteins; lysozyme, ribonuclease A, cytochrome C, α-chymotrypsinogen, α-lactalbumin, ovalbumin, transferrin, and myoglobin were baseline separated within 25 min by 25 mM sodium phosphate buffers (pH 7.0) containing 100 µg/mL QC.

    A simple and convenient method has been developed for the synthesis of esters from the corresponding carboxylic acids and alkyl halides by using a stoichiometric amount of tetrabutylammonium fluoride (Bu4NF) as the base. The reaction of carboxylic acids and a Bu4NF/THF solution in DMF or THF as the solvent generates carboxylate ions in situ. The carboxylate ions thus generated and accumulated are highly reactive. They are then allowed to react with alkyl halides as the electrophiles, and afford the corresponding esters in moderate to good yields. The reaction without Bu4NF does not afford any product; therefore, Bu4NF seems to play an important role as the base in these reactions. A bulky countercation such as the tetrabutylammonium cation seems to increase the reactivity of the carboxylate ions in the solution phase.

    We conducted team-based learning (TBL) with interdisciplinary lectures as a part of "Introduction to Pharmacy", divided among the pharmacy department's six pharmacist education curricula in the first semester. The interdisciplinary lecture is led by seven lecturers, each specializing in one area: cell biology, biochemistry, chemistry, public health pharmacology, pharmacokinetics, and clinical science. This lecture's purpose is to demonstrate to the students that all field subjects relate to each other and they must learn the basic science subjects to understand pharmaceutical sciences. The TBL contents have two themes, "cancer" and "aspirin", each of which had two lectures, each 90 minutes long and were conducted using TBL as expansive learning. On receiving knowledge of a wide range of fields in one lecture, a small number of students indicated that they were unable to understand the contents very well. However, in the questionnaire about TBL, many students reported "I have understood" and "I have enjoyed studying" using TBL, especially group readiness assessment test (GRAT). By incorporating TBL, they reported "increasing eagerness to learn pharmacy". Overall, students seem to have accepted TBL favorably, but they still find peer review difficult. We believe that their discomfort with peer review results from their unfamiliarity in evaluating others, and the time before the evaluation is short because TBL is conducted only twice.

    We are reporting on a new method of constructing dearomatized compounds from alpha-substituted aryltriazenes. Deprotonation occurs at C atom alpha to N3. Nucleophilic attack of generated anion at the ortho-position of aryl group forms a new carbon-carbon bond. A stereoselective reaction was observed when the substituents on the C alpha to N3 are tied together in either a pyrrolidine or a piperidine. The product of this reaction possessed an interesting dearomatized tetrahydrobenzotriazine framework. (c) 2006 Elsevier Ltd. All rights reserved.

    A new approach to benzylamines using triazene compounds has been developed that is facilitated by the lithiation of aryltriazenes followed by treatment with an electrophile. The regioselectivity of the reaction can be controlled by means of the substituents in the aryl group. The reaction contains the following steps: intramolecular carbon-carbon bond formation involving lithiation of an alkyl group on a 3-nitrogen atom; a 1,2-proton shift; and the subsequent release of nitrogen gas. Through the use of a deuterated triazene, we were able to determine that the reaction proceeds through a 1,2-proton shift. (c) 2006 Elsevier Ltd. All rights reserved.

    Molecular orbital calculations revealed that the introduction of a silyl group onto the 2-position of 1,3-dithiole caused significant decrease of the ionization potential and that 2-silyl-1,3-dithioles served as a pseudo π-electron system. The silyl group could also be utilized as a bridge for linking π-electron systems to achieve artificial stacking. These concepts led us to the design and synthesis of silyl-substituted 1,3-benzodithioles as candidates for new electron donors. The oxidation potential of monosilyl-substituted 1,3-benzodithiole was found to be significantly less positive than that of the parent 1,3-benzodithiole. The introduction of the second silyl group caused further decrease of the oxidation potential. Compounds composed of two 1,3-benzodithiole units linked by a silyl group were also synthesized. These showed comparable oxidation potentials to those of the corresponding monomeric compounds. The effect of stannyl-substitution onto the 2-position of 1,3-dithiole was found to be larger than that of silyl-substitution. The effects of silyl- and stannyl-substitution for related systems such as thioanisole and 1,3-dithiane were also studied.

    The C-Si and C-Sn σ orbitals are higher in energy than C-H or C-C σ orbitals, and therefore can interact with neighboring π systems, non-bonding orbitals of heteroatoms, and other σ systems such as those of C-Si and C-Sn. Such interactions cause an increase of the HOMO level which in turn favors electron transfer.

    The introduction of tin on the carbon adjacent to the oxygen of aliphatic ethers results in significant decrease in the oxidation potentials. The effect of tin is much larger than that observed for silicon. Preparative electrochemical oxidation of α-alkoxystannanes results in selective cleavage of the carbon-tin-bond and introduction of a nucleophile such as an alcohol onto the carbon. © 1992.
