WIPO Patent Application WO/2019/200501
Kind Code:
Disclosed by the present invention are a water-soluble inlaid thorium fullerene, a preparation method therefor and an application thereof. Specifically, the method comprises: first evacuating a reaction chamber that is equipped with electrodes to form a vacuum, then filling a He atmosphere having a pressure of 2.5-3.5×104 Pa, next using a graphite rod having spectral purity as a cathode and using a hollow graphite rod filled with a mixture of ThO2/graphite powder as an anode, and performing arc discharge by using the anode and cathode at a current intensity of 90-100 A in the described mixed atmosphere so as to prepare inlaid thorium fullerene Th@C82. After chromatographic purification, a mixed solvent of hydrogen peroxide and ammonia water is added (the ratio being 7: 3) and heated at 50°C for 3 h to prepare water-soluble inlaid thorium fullerene. The present invention may modify the surface of Th@C82 with a hydrophilic group, while the amino group on the surface is further facilitated in coupling with other biologically active molecules so as to improve targeting performance and achieve the effect of targeted diagnosis and treatment, thus providing a wide space of selection for subsequent development.
