    • The invention provides a method for the formation of a tissue-targeting thorium complex, said method comprising; a) forming an octadentate chelator comprising four hydroxypyridinone (HOPO) moieties, substituted in the N-position with a methyl group, and a coupling moiety terminating in a carboxylic acid group; b) coupling said octadentate chelator to at least one tissue-targeting moiety targeting prolyl endopeptidase FAP; and c) contacting said tissue-targeting chelator with an aqueous solution comprising an ion of at least one alpha-emitting thorium isotope. A method of treatment of a neoplastic or hyperplastic disease comprising admistration of such a tissue-targeting thorium complex, as well as the complex and corresponding pharmaceutical formulations are also provided.
    • 本发明提供了形成组织靶向钍络合物的方法,所述方法包括: a)形成包含四个羟基吡啶酮(HOPO)部分的八齿螯合剂,所述羟基吡啶酮部分在N位被甲基取代,并且偶联部分以羧酸基团终止; b)将所述八齿螯合剂偶联至至少一种靶向脯氨酰内肽酶FAP的组织靶向部分; 和c)使所述组织靶向螯合剂与包含至少一种α-发射钍同位素的离子的水溶液接触。 还提供了治疗肿瘤性或增生性疾病的方法,包括给予这种组织靶向钍络合物以及复合物和相应的药物制剂。
