Abstract: Disclosed is an anticancer prodrug that disturbs energy metabolism in cancer cells to overcome drug resistance. The anticancer prodrug has a structure including a pyruvate dehydrogenase kinase (PDK) inhibitor moiety, a mitochondrial targeting group, and an anthracycline moiety reversibly connected to the PDK inhibitor moiety and the targeting group.

Abstract: The present invention relates to a repurposed antibiotic compound for the treatment of cancer with minimal nuclear gene damage and an anticancer pharmaceutical composition comprising same. Since the repurposed antibiotic compound has a therapeutic effect in a manner that targets only the mitochondria of cancer cells, the modified antibiotic compound does not cause gene degeneration unlike conventional chemotherapy which damages nuclear DNAs to kill cancer cells, thereby preventing the recurrence of cancer. In addition, a mitochondria targeted therapy using the compound according to the present invention can effectively treat malignant tumors that are difficult to treat due to acquiring drug resistance by general anticancer treatment.

Abstract: Provided is a rehosting method for converting a mainframe system environment into an open system environment. The rehosting method rebuilds hardware (HAV) and software (SAV) of a company-data processing mainframe system environment to be appropriate for an open system environment, converts data included in a database or a general file to be appropriate for the open system environment, and reuses an application program. Thus, the rehosting method can be implemented at low cost within a short time and can significantly reduce maintenance cost.

Abstract: Novel calix[4]arene dibenzo crown ethers useful to selectively extract cesium are represented by the formula: wherein R is a C.sub.1 -C.sub.10 normal alkyl, a phenyl or a methoxyphenyl, R' is hydrogen, p-tert-butyl or a C.sub.1 -C.sub.10 normal alkyl, R" is a C.sub.1 -C.sub.10 normal alkyl, and n is an integer of 0-2. The novel compound is prepared at high yields by introduction of benzene rings into the crown ether ring of calix[4]arene crown-6-ether. The calix[4]arene dibenzo crown ethers are superior in selective absorptivity for cesium ions by virtue of their 1,3-alternate conformational structure and thus, can be used as selective extractants able to separate cesium ions at a high efficiency.
