PRECURSOR FOR LABELING THERAPEUTIC AGENT FOR LIVER CANCER AND METHOD FOR MANUFACTURING THE SAME

摘要

A precursor for labeling therapeutic agents for liver cancer and a method for manufacturing the same are revealed. The chemical structure of the precursor has a ligand linked to complex compounds of radioisotopes. Moreover, the chemical structure of the precursor further includes a specific functional group soluble in Lipiodol or having properties of Lipiodol. Thus the radioisotopes attached to the precursor are allowed to retain in hepatic tissues of patients with liver cancer for internal radiation therapy of liver cancer.

主权项

1. A precursor for labeling therapeutic agents of liver cancer is represented by the following structural formula: wherein a functional group R is 8-heptadecenyl group or 5,6-diiodotetradecyl group.
