  • Anticancer agent and side-effect-alleviating agent
    Patent number: 9907852
    Abstract: The purpose of the present invention is to provide an anticancer agent for potentiating an antitumor effect, alleviating side effects, and further extending the survival rate by concomitant use with a component having an anticancer effect. An anticancer agent combining arctigenin and a component other than arctigenin that has an anticancer effect, in which the anticancer agent may be a combination drug or may be a kit configured from a formulation containing arctigenin and a formulation containing a component that has an anticancer effect, and the concomitant use of arctigenin and the component having an anticancer effect more strongly inhibits tumor growth and reduces the proportion of cancer stem cells in the tumor, making it possible to extend the total survival time and to alleviate side effects caused by the component having an anticancer effect.

  • Anti-cancer agent
    Patent number: 9700572
    Abstract: The present invention is intended to provide a novel anticancer agent which is effective to a cancer. After administering an agent prepared using burdock fruit extract to a pancreas cancer patient so that a dose of arctigenin was 100 mg or more per day, the tumor reducing effect was observed, and, in addition, lowering of tumor markers was confirmed. The present invention provides an anticancer agent containing arctigenin, wherein a dose of the arctigenin is 100 mg or more per day. In addition, the present invention provides the anticancer agent containing arctigenin and arctiin at a weight ratio of arctigenin/arctiin=0.7 to 1.3.
