The present invention relates to a novel diaminedithiol derivative or a pharmaceutically acceptable salt thereof; radiorhenium or radiotechneticum complex thereof; a composition for treating liver cancer comprising the radiorhenium complex and lipiodol; and, a preparative kit of the composition for treating liver cancer.
In the composition according to the invention, the diaminedithiol derivative is a novel compound in which long chain alkyl groups were introduced to diaminedithiol, capable of forming a radiorhenium or radiotechnetium complex thereof with an ease and leading to stronger van der Waals bonds with lipiodol. As a result, the complex becomes more stable in a medium, lipiodol, whereby the composition of the invention exhibits a high accumulation rate in liver cancer tissue when injected via hepatic artery, thereby capable of achieving an efficient treatment of liver cancer.
本发明涉及一种新型二氨基二硫衍生物或其药学上可接受的盐;其辐射铼或辐射钷配合物;一种用于治疗肝癌的组合物,包括辐射铼配合物和碘油;以及治疗肝癌的组合物的制备工具包。
在本发明的组合物中,二氨基二硫衍生物是一种新化合物,其中引入了长链烷基,能够轻松形成辐射铼或辐射钷配合物,并与碘油形成更强的范德华键。因此,该配合物在介质碘油中更加稳定,当通过肝动脉注射时,本发明的组合物在肝癌组织中具有高积累率,从而能够实现有效的肝癌治疗。
