  • Patent number: 9408911
    Abstract: The present invention relates to an anticancer prodrug consisting of peptide of acetyl-SEQ ID NO: 1-linker-anticancer drug. The anticancer prodrug effectively provides an anticancer drug unstable in acid and base, such as doxorubicin, in a form of prodrug. Thus, the anticancer prodrug exists as a non-toxic inactive form when administered into the body, but effectively releases the anticancer drug as an active ingredient in the target area in the presence of caspase activated by radiation or UV treatment after administered into the body. Accordingly, the anticancer drug exhibits selective anticancer effects on cancer cells, thereby maximizing the therapeutic effect and minimizing the side-effects of chemotherapy.

  • Patent number: 9319722
    Abstract: The method of providing a mobile IPTV service, performed in a terminal that receives streams of all channels belonging to a channel group of a currently viewed channel, includes, when a channel is selected, determining whether the selected channel and the currently viewed channel belong to the same channel group, and when the selected channel and the currently viewed channel are determined to belong to the same channel group, decoding, by the terminal, an IPTV channel stream of the selected channel within a currently received channel. Therefore, since the channel group is generated based on channel selection preference, and a multicast stream including a channel stream of the channel group is broadcast, it is possible to decrease average processing complexity and to guarantee rapid channel change when a user changes the channel to another channel in the same channel group.
