  • Patent number: 8916602
    Abstract: The present invention relates to novel fusarisetin compounds separated from Fusarium sp. FN080326 and having an anticancer activity, and to the use thereof. In detail, novel fusarisetin compounds separated and purified from Fusarium sp. FN080326, which is in turn separated from a soil sample, have an inhibitory activity on the proliferation and transfer of cancer cells such as breast cancer cells, liver cancer cells or myeloid leukemic cells. Therefore, the compounds can be effectively used for anticancer compositions containing the compounds as active ingredients.
    Type: Grant

  • Patent number: 6524161
    Abstract: A luminous toy capable of emitting light at any time anywhere without having to worry about a power shortage and failing to turn off a switch and capable of preventing environmental pollution. The luminous toy includes a toy body provided with a piezoelectric element which induces a voltage when it is strained, a rectifying circuit for rectifying the voltage generated from the piezoelectric element, a capacitor for smoothing the voltage rectified by the rectifying circuit and a luminous element connected in parallel to the capacitor. The luminous toy also includes a strain generating mechanism for generating strain for straining the piezoelectric element.

  • Patent number: 5303491
    Abstract: A figure moving article capable of accomplishing unique and unexpected movement sufficient to exhibit unexpected movements. The figure moving article includes a cylindrical container having a peripheral wall formed of a flexible material. In the container is arranged a bending structure which is actuated to cause the container to carry out bending motion. Also, a motor is received in the container in a manner to be operatively connected to the bending structure to actuate the bending structure and a motor drive circuit for driving the motor is arranged in the container. The bending structure is operatively connected to the container so as to transmit the actuation of the bending structure to the container, resulting in the container exhibiting bending movement.
