Yonago Acta Med. 2015 Jun;58(2):81-4. Epub 2015 Aug 18.

BACKGROUND: Few studies compare mood in tobacco cessation patients with mood in continuing smokers and then estimate the effects of a tobacco cessation program according to status of mood. We investigated whether mood in patients (n = 7) dependent...

Photochromism in sound-induced alignment of a diarylethene supramolecular nanofibre.

Chemical communications (Cambridge, England)

Hotta Y, Fukushima S, Motoyanagi J, Tsuda A.
PMID: 25582095
Chem Commun (Camb). 2015 Feb 18;51(14):2790-3. doi: 10.1039/c4cc09702e.

A photochromic supramolecular nanofibre, composed of a diarylethene derivative, exhibits hydrodynamic alignment upon exposure to the audible sound. The aligned nanofibre outputs linear dichroism (LD), whose wavelength region can be switched reversibly with UV and visible light.

Control of reaction pathways in the photochemical reaction of a quinone with tetramethylethylene by metal binding.

PMID: 24947667
Org Biomol Chem. 2014 Sep 28;12(36):7004-17. doi: 10.1039/c4ob00659c.

The present study reports a novel supramolecular photochemical reaction that focuses on the direct electronic interactions between a host reaction substrate and guest metal salts. The reaction pathways in the photochemical reactions of quinone derivatives bearing a methoxy group...

Carbacaprazamycins: Chemically Stable Analogues of the Caprazamycin Nucleoside Antibiotics.

ACS infectious diseases

Ichikawa S, Yamaguchi M, Hsuan LS, Kato Y, Matsuda A.
PMID: 27622529
ACS Infect Dis. 2015 Apr 10;1(4):151-6. doi: 10.1021/id5000376. Epub 2015 Feb 19.

Carbacaprazamycins, which are chemically stable analogues of caprazamycins, were designed and synthesized. These analogues were active against drug-resistant bacterial pathogens such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci, and their activities were comparable to those of the parent caprazamycins....

Significant association between glycemic status and increased estimated postglomerular resistance in nondiabetic subjects - study of inulin and para-aminohippuric acid clearance in humans.

Physiological reports

Yasumoto M, Tsuda A, Ishimura E, Uedono H, Ohno Y, Ichii M, Ochi A, Nakatani S, Mori K, Uchida J, Emoto M, Nakatani T, Inaba M.
PMID: 25742958
Physiol Rep. 2015 Mar;3(3). doi: 10.14814/phy2.12321.

We investigated whether glomerular hemodynamic parameters in nondiabetic subjects, including healthy subjects, are associated with glycemic status indices, by simultaneous measurement of inulin (Cin) and para-aminohippuric acid (CPHA) clearance. Twenty-six subjects (age 49.5 ± 13.3 years; 13 men and...

Clin Proteomics. 2014 Dec 11;11(1):44. doi: 10.1186/1559-0275-11-44. eCollection 2014.

BACKGROUND: A combination treatment of interferon and ribavirin is the standard and the commonly used treatment for chronic hepatitis C (CHC). Developing noninvasive tests like serum indicators that can predict treatment outcome at an early stage of therapy is...

Doubly meso-beta-Linked Diporphyrins from Oxidation of 5,10,15-Triaryl-Substituted Ni(II)- and Pd(II) - Porphyrins.

Angewandte Chemie (International ed. in English)

Tsuda A, Nakano A, Furuta H, Yamochi H, Osuka A.
PMID: 10671257
Angew Chem Int Ed Engl. 2000 Feb;39(3):558-561. doi: 10.1002/(sici)1521-3773(20000204)39:3<558::aid-anie558>3.0.co;2-g.

Lower oxidation potentials than for the monomeric starting materials are displayed by the diporphyrins obtained by one-electron oxidation with tris(4-bromophenyl)ammonium hexachloroantimonate [see, for example, Eq. (1)]. This and the strong red shift observed for the Soret bands of the...

The Wittig reaction of 1-[3,5-O-(1,1,3,3-tetraisopropyldisiloxane-1,3-diyl)-beta-D-erythro-pentofuranos-2-ulosyl]uracil (6) with Ph(3)P=CHCN afforded (Z)-2'-cyanomethylene derivative 7 exclusively. The (E)-isomer was accessed from its (Z)-isomer through a sequence of addition of thiophenol to the 2'-cyanomethylene moiety of the (Z)-isomer from the alpha-face, selectively, and...
