Abstract
A radioactive material for inhibiting cancer and a preparation method thereof are disclosed. The radioactive material for inhibiting cancer is M-SOCTA-Z and M is a radioactive nuclide such as 188Re or 99mT while Z is protein or peptides having amino acid with NH or NH2 group. The preparation method of the radioactive material for inhibiting cancer includes steps of: reacting SOCTA with protein or peptide. Ester (—COOR) in SOCTA reacts with amines (—NH, —NH2) in protein or peptide to form peptide bond. Thus SOCTA-protein or SOCTA-peptide complex is produced. Then these SOCTA-protein complex reacts with radioactive nuclide M so as to generate M-SOCTA-protein or M-SOCTA-peptide. In an embodiment of the present invention, monoclonal antibody Herceptin is applied to bind with SOCTA and in combination with radiation-based therapy, effects of cancer treatment (such as breast cancer) are enhanced.
