Abstract: An apparatus and method for converting a frequency of a high frequency signal received from an antenna in an ultra wide band communication system transmitting and receiving using at least two reference frequencies. The method includes generating generation frequencies having frequencies set to convert the frequency of the high frequency signal and mixing the frequency of the high frequency signal and the generation frequencies in at least two stages.

Abstract: The present invention is related to novel use of photopyrin compounds useful as an anticancer agent by way of reproducing singlet state oxygen radical and the inventive compounds showed potent inhibition effect on colon cancer, cervical cancer, gastric cancer, cystic cancer or lung cancer. Accordingly, the porphyrin compound of the present invention can be useful in treating or preventing colon cancer, cervical cancer, gastric cancer, cystic cancer or lung cancer in human or mammal.

Abstract: The present invention is related to novel photopyrin compounds and the pharmaceutically acceptable salt thereof useful as an anticancer or photodynamic diagnostic agent by way of reproducing singlet state oxygen radical and the inventive compounds have superior advantages such as excellent photon yield to produce singlet oxygen, good physical stability and potent cell cytotoxicity to conventional photosensitizer. The present invention also provides a pharmaceutical composition comprising a novel photopyrin compound of formula (I) to (VII) or a pharmaceutically acceptable salt thereof as an active ingredient for preventing or treating various cancers such as stomach cancer, liver cancer, lung cancer, cervical cancer and breast cancer in human or mammal together with a pharmaceutically acceptable carrier.
