Hokuriku University is a private university located in Kanazawa, Ishikawa, Japan. Founded in 1975, the university is locally nicknamed Hokudai, though typically the term is used nationwide to refer to Hokkaido University. It was originally founded as a single-department college with the Faculty of Pharmaceutical science. Later, the Faculty of Foreign Languages and the Faculty of Law were established in 1987 and 1992, respectively. The School of Future Learning was established in 2004, making it the newest faculty in the university.As of the end of March 2005, Hokuriku University owns 4.44% of the outstanding stock in FM Tokyo.

Quantification of BMD is being used as the main method to diagnose osteoporosis and measurement accuracy has dramatically improved. However, essential clinical parameters of osteoporosis include more dynamic markers such as bone metabolic markers. Bone metabolism undergoes daily dynamic changes, and even with the same BMD, the metabolic state differs and the pathologic significance also differs. Therefore, to use BMD measurement as a dynamic marker, one must wait for an observation period of 6 months to 1 year before remeasurement, whereas bone metabolic markers accurately reflect the state of bone metabolism at the point in time of the measurement. Bone metabolic markers can also be used as a guide to selecting pharmacotherapy. When there is doubt about choosing a drug, the use of bone metabolic markers can enable more appropriate selection. Furthermore, to evaluate the effects of drug therapy on disease improvement, assessing the state of bone metabolism at the time of diagnosis is recommended whenever possible. However, if a decision is made to select treatment with little influence on bone metabolism, then measuring bone metabolic markers to monitor drug treatment effects has little clinical significance. Recently the clinical application of bone metabolic markers have been achieved significant progress and the measurements of these indices give us better understanding of pathological of osteoporosis. Therefore, it is very important to guide the proper application and assessment of bone metabolic markers in clinical practice.

We examined the anti-influenza virus activity of tricin, 4',5,7-trihydroxy-3',5'-dimethoxyflavone, against five viruses: A/Solomon islands/3/2006 (H1N1), A/Hiroshima/52/2005 (H3N2), A/California/07/2009 (H1N1pdm), A/Narita/1/2009 (H1N1pdm) and B/Malaysia/2506/2004 strains in vitro and against A/PR/8/34 virus in vivo. The effect of tricin was studied by an infectious virus yield reduction assay. The anti-influenza virus mechanism of the tricin was examined by western blot analysis, real-time reverse transcriptase PCR analysis, haemagglutination inhibition (HI) assay and neuraminidase (NA) inhibition assay. The anti-influenza virus efficacy of tricin was further examined in a murine influenza virus infection model. Tricin of 3.3 to 30 μM significantly reduced seasonal A (H1N1), (H3N2) viruses, novel A (H1N1pdm) virus, as well as B virus in a dose-dependent manner. The 50% effective concentrations of tricin were 3.4 μM for seasonal A (H3N2) virus, 4.9 μM for B virus and 8.2 μM for A/Narita (H1N1pdm) virus. Tricin decreased the expression of haemagglutinin (HA) protein and matrix (M) protein, and messenger RNA expression of HA and M of influenza virus in the infected cells. Tricin exhibited little or no effects on influenza virus HI and NA activities. In the mouse infection model, tricin was significantly effective in reducing body weight loss, and also effective in prolonging survival times of infected mice. Tricin was indicated to possess anti-influenza virus activity and to ameliorate body weight loss and survival rate of influenza-A-virus-infected mice. Tricin is a novel compound with potential anti-influenza virus activity in vitro and in vivo.

The present invention provides a compound represented by the formula (I): or a salt thereof; and a method of quantitatively analyzing an amino group-containing target substance, including labeling a target substance in samples by using, as a labeling compound, two or more of such compounds having a mutually different mass due to isotope labeling, to confer a mass difference to the target substance between two or more samples, and the like.

The treatment of the o-ethynylphenyl isothiocyanates with primary and secondary amines in 1,2-DCE, followed by the addition of I2 and then heating resulted in the regio- and stereoselective tandem addition- iodocyclization to give the (4E)-2-amino-4-(1-iodomethylidene)benzo[d][1,3] thiazine derivatives as the sole product in high yields via the 6-exo-dig mode cyclization. The 2-alkoxy-1,3-benzothiazines were similarly produced from the o-ethynylphenyl isothiocyanates and the corresponding sodium alkoxides. © 2013 Elsevier Ltd. All rights reserved.

A convenient and successful one-pot preparation of the 2- aminobenzoselenazoles via the phenylselenoureas has been accomplished by the copper-catalyzed ligand-free reaction of the 2-iodoanilines and isoselenocyanates; the intermediate, selenoureas, were isolated, and quantitatively transformed into the selenazaoles. © 2010 Elsevier Ltd.
