Publication number: 20150160152Abstract: An electrode for superoxide anions characterized by comprising a conductive component and, superimposed on a surface thereof, a film resulting from electrolytic polymerization of a metal thiofurylporphyrin/axial ligand complex; and a sensor for measuring a superoxide anion concentration including the same. The electrode for superoxide anions, by virtue of not only the excellent performance of electrode provided with the metal porphyrin complex polymer film, but also the presence of the axial ligand, can prevent poisoning by a catalyst poison such as hydrogen peroxide. Accordingly, in any of in vitro or in vivo environments, this electrode for superoxide anions enables detection of superoxide anion radicals without suffering any influence from a catalyst poison such as hydrogen peroxide. Moreover, quantitative assay of superoxide anions can be performed by the use of this electrode for superoxide anion in combination with a counter electrode or a reference electrode.Type: ApplicationFiled: November 3, 2014Publication date: June 11, 2015Inventors: Makoto Yuasa, Kenichi Oyaizu, Aritomo Yamaguchi, Masuhide Ishikawa, Katsuya Eguchi, Tomohiro Kobayashi, Satoshi Tsutsui, Yuujirou Toyoda

Publication number: 20120039987Abstract: A niosome having a metalloporphyrin complex embedded therein comprising a cationized metalloporphyrin complex and a niosome-forming substance. The niosome having a metalloporphyrin complex embedded therein has an SOD activity, can interact with superoxide anionic radicals (O2?.) as a target, and can reduce these radicals without fail. The niosome having a metalloporphyrin complex embedded therein can reach cells in living bodies such as cancer cells due to properties of a niosome. Therefore, the niosome having a metalloporphyrin complex embedded therein can exhibit an excellent effect of treating cancer by reducing O2?. in cancer cells. In addition, since the effect is selective, the niosome can be used as a novel anticancer agent without side effects. Moreover, the niosome having a metalloporphyrin complex embedded therein can be retained in the blood while exhibiting a superior antioxidation effect. The niosome can thus protect living bodies from hindrance brought about by active oxygen species.Type: ApplicationFiled: July 14, 2011Publication date: February 16, 2012Applicant: Makoto YUASAInventors: MAKOTO YUASA, KENICHI OYAIZU, ARITOMO YAMAGUCHI, YUKIHIRO HANYUU, KAZUNORI KASAHARA, MASAYASU KOMURO
