Abstract
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 HER2; 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.
