  • Patent number: 10664626
    Abstract: A mechanism to prevent unauthorized physical use of an electronic device includes a main circuit board, a plurality of light sources, a plurality of sensors, a base, a plurality of optical members, and a magnetic member. The base comprises a base body and a plurality of guiding members. Each optical member comprises a main body and a magnetic portion. The main body of each optical member can change either a direction of propagation of light or a wavelength of light emitted from a light source, or both, and can propagate such light to a sensor which can forward to a control unit electrical signals representing a password input. When the electronic device is detached, the magnetic member attracts the magnetized optical members into random disorder on the cover, thereby destroying the predefined order.

  • Publication number: 20200054593
    Abstract: This application discloses a D-3-phosphoglycerate dehydrogenase allosteric inhibitor and the use thereof. In one class is the benzoyl hydrazine compound for the allosteric site MDL-1 of the enzyme, and the other class is the furan compound for the allosteric site MDL-2 of the enzyme. In vitro enzymatic activity tests, cell viability tests and mouse xenograft model experiments confirm that the two classes of allosteric inhibitors can specifically inhibit the activity of D-3-phosphoglycerate dehydrogenase and delay the growth of cancer cells by reducing the overexpression of the enzyme in cancer cells. Same are used alone or in combination, or in combination with other anti-cancer drugs and can treat, prevent, or inhibit tumor diseases, including breast cancer, colon cancer, melanoma and non-small cell lung cancer.
