Abstract: The present invention relates to an anticancer agent capable of overcoming EGFR-TKI resistance in KRAS mutant cancer. GW8510 according to the present invention is an effective inhibitor against oncogenic mutation, especially, KRAS mutation, which is associated to resistance of the anticancer agent EGFR inhibitor and remarkably inhibits expression of both the wild-type and various mutants of KRAS, whereby the drug itself exhibits an anticancer effect, surmounts anticancer agent resistance, and noticeably promotes the death of anticancer agent-resistant cancer cells when used in combination with an anticancer agent. Thus, the inhibitor finds advantages applications in treating cancers, especially anticancer agent resistant cancers.

Abstract: The present invention relates to an triboelectric nanogenerator using an ionic elastomer that increases internal electric capacity and allows a large amount of electric charge to be located on a surface to generate a large amount of electrical energy. The triboelectric nanogenerator according to the present invention includes a first electrode; an ionic elastomer disposed on the first electrode and including an elastomer and an ionic liquid; a second electrode disposed to be spaced apart from the first electrode and electrically connected to the first electrode; and an insulator disposed under the second electrode, selectively contacting the ionic elastomer, and formed of a material that has a negative charge compared to the ionic elastomer. In this case, the ionic elastomer and the insulator are brought into contact with each other or are separated from each other by external force, and electrical energy is generated between the first and second electrodes when the ionic elastomer and the insulator are brought into contact with each other and separated from each other.
