Patent number: 11983680Abstract: An intelligent monitoring system for waste disposal and the method thereof are provided, which include a plurality of operational devices and stages. First, a transportation stage is performed to loading a transport vehicle with a waste so as to transport the waste to a disposal station for further treatment. A camera and a sensor for detecting abnormal conditions are installed any one of the operational devices or installed in the operational path of any one of the operational devices. The camera records the videos of the operational stages, captures the images from the videos and recognizes the images in order to determine whether the abnormal conditions occur in any one of the operational stages. Alternatively, the camera is triggered to capture the images and recognize the images after the abnormal conditions are detected by the sensor in order to determine whether the abnormal conditions actually occur.Type: GrantFiled: June 12, 2021Date of Patent: May 14, 2024Assignee: CHASE SUSTAINABILITY TECHNOLOGY CO., LTD.Inventors: Yung-Fa Yang, Tsung-Tien Chen, Shao-Hsin Hsu, Bo-Wei Chen, Chia-Ching Chen, Ming-Hua Tang

Patent number: 9084779Abstract: Novel compounds which are derivatives of tetra-O-methyl nordihydroguaiaretic acid (NDGA), as well as pharmaceutically acceptable salts, solvates, and stereoisomers thereof are provided. These NDGA derivatives have a nitroimidazole moiety and these derivatives show preferential toxicity to hypoxic cells as hypoxic cytotoxins. Their cytotoxicity toward hypoxic cells is a result of abstraction of hydrogen from target molecules by free radicals formed in the reduction of the nitro group. This makes the disclosed compounds an effective anti cancer drug because hypoxic cells are generally considered to be more resistant to anti cancer drugs than normal cells. Pharmaceutical compositions comprising such compounds, as well as methods of use, and treatment for cancers, including hepatocellular carcinoma, breast cancer and prostate cancer, are also provided.Type: GrantFiled: May 30, 2012Date of Patent: July 21, 2015Assignee: The Johns Hopkins UniversityInventors: Ru Chih C.

Patent number: 8420692Abstract: Reaction of nordihydroguaiaretic acid with various alkyl chlorides, 1-piperidinecarbonyl chloride, methyl chloroformate, or 1,1?-carbonyldiimidazole under alkaline conditions produced the corresponding phenol ethers, carbamates and carbonates, respectively, in 67-83% yields (Scheme 1 and Scheme 2). Among these derivatives, the nitrogen-containing compounds were converted to the corresponding hydrochloride salts. Having good solubility, these NDGA derivatives were found to be stable in aqueous solution. These new compounds exerted potent activities against HIV Tat-regulated transactivation in cos-7 cells. The most active transcription inhibitor compound of this series 5b (P4N, Tetrapiperidino NDGA, meso-2,3-dimethyl-1,4-bis(3,4-[2-(piperidino)ethoxypehnyl])butane tetrakishydrochloride salt) has an IC50 of 0.88 ?M.Type: GrantFiled: April 6, 2010Date of Patent: April 16, 2013Assignee: The Johns Hopkins UniversityInventors: Ru Chih C.
