  • Patent number: 7459471
    Abstract: The present invention provides an inclusion compound having a cucurbituril derivative of the formula 1 as a host molecule and a metal complex of the formula 2 as a guest molecule. A pharmaceutical composition having an anticancer effect can be obtained by using the inclusion compound according to the present invention. The pharmaceutical composition can prevent effective components from being biologically degraded in vivo and can exhibit continuous drug effect for a long time just by a single dosage by controlling the release time of the platinum complex once it reaches target tumor cells.

  • Publication number: 20080290028
    Abstract: Provided are a stationary phase and a column using a cucurbituril-bound silica gel, and a method of separating taxane using the column. The taxane separation method includes: preparing a column for taxane separation, the column being packed with a stationary phase including a cucurbituril-bound silica gel in which a cucurbituril represented by Formula 1 or 2 is covalently bound to a modified silica gel represented by Formula 3; dissolving a taxane powder in a solvent to prepare a taxane-containing solution; applying the taxane-containing solution to the column; supplying a mobile-phase solvent to the column to obtain a taxane extract from the column; and purifying taxane from the taxane extract. Therefore, highly purified taxane can be separated from a low-purity crude taxane extract.
