  • Patent number: 10385087
    Abstract: Disclosure of the present invention relates to a method for synthesis of a xylose derivative, which comprises protecting a xylose with a protective group, followed by incorporating to a halogen atom as a leaving group; removing the protective groups and using water-soluble ligands to carry out a Suzuki cross-couplings reaction with a palladium catalyst in a water solution. Ten new xylose derivatives as obtained by the method are also provided.

  • Patent number: 10287168
    Abstract: Disclosed is a method of manufacturing graphene material, including steps of first oxidation, first heating, second heating, second oxidation, separation, drying, first ultrasonic vibration, reduction, second ultrasonic vibration, heating, and filtration. The first oxidation and the second oxidation respectively employ the first oxidant and the second oxidant with different strength of oxidation to appropriately control the range of the ratio of carbon vs. oxygen content in the graphene oxide. Therefore, the resultant graphene material through the reduction process has resistivity within 1.45˜150 ?/cm.

  • Patent number: 8552029
    Abstract: Provided is a quinoline derivative of Chemical Formula (I): wherein, R1 is a substituted or unsubstituted phenyl group, R2 is a halogen, and R3 is a substituted or unsubstituted phenyl group, and one of the carbon atoms in the phenyl ring of the phenyl group is optionally substituted by a nitrogen atom (N). The quinoline derivative can efficiently inhibit cancer cell proliferation and can be used for treating cancer, especially for treating cancers related to the Janus kinase-signal transducers and activators of transcription (JAK-STAT) pathway and/or the mitogen-activated protein kinase (MAPK) pathway.
