4-Acetyl-N,N-diisopropyl-1-benzylnicotinamidinium ion (ABNA(+)) and 1-benzyl-4-phenylnicotinamidinium ion (PhBNA(+)) were newly synthesized as NAD(+) analogues to examine the electron-transfer reactivity and the effects of metal ions on the reactivity in comparison with those of 1-benzylnicotinamidinium ion (BNA(+)) and 1-methyl-4-phenylpyridinium ion(More)
Photoinduced electron transfer from a variety of electron donors including alkylbenzenes to the singlet excited state of acridine and pyrene is accelerated significantly by the presence of scandium triflate [Sc(OTf)(3)] in acetonitrile, whereas no photoinduced electron transfer from alkylbenzenes to the singlet excited state of acridine or pyrene takes(More)
Quantification of tumor-associated mRNA extracted from blood cells/tissues containing tumor cells is used for evaluation of treatment efficacy or residual tumor cell burden in tumors including leukemia. However, this method using tumor cell-containing blood/tissue is difficult to evaluate the whole tumor cell burden in the body. In order to establish an(More)
PMDC05, a leukemic plasmacytoid dendritic cell (pDC) line which was established in our laboratory, showed a capacity of generating antigen-specific cytotoxic T lymphocytes (CTLs). In order to enhance an antigen presenting ability of PMDC05, PMDC05 was transduced with CD80 gene by lentiviral vector, which was named as PMDC11. PMDC11 displayed a strong(More)
N-Acetylamino acids were derivatized with 9-anthryldiazomethane to the corresponding esters. The anthryl esters were separated by high-performance liquid chromatography and detected fluorimetrically (excitation at 365 nm; fluorescence emission measured at 412 nm). N-Acetyl derivatives of Asn, Gln, Ser, Thr, Gly, Ala, Tyr, Pro, Met, Val, Ile and Leu as well(More)
A neutral polysaccharide, named glycyrrhizan UC, was isolated from the root of Glycyrrhiza uralensis Fischer. It was homogeneous on electrophoresis and gel chromatography, and its molecular mass was estimated to be 69,000. Glycyrrhizan UC is composed of L-arabinose:D-galactose:D-glucose:L-rhamnose in the molar ratio of 10:30 27:1. Methylation analysis,(More)
