  • NIOSOME HAVING METAL PORPHYRIN COMPLEX EMBEDDED THEREIN, PROCESS FOR PRODUCING THE SAME AND DRUG WITH THE USE THEREOF
    Publication number: 20120039987
    Abstract: 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.
