The invention relates to nucleophile-reactive sulfonated compounds used as precursors to (radio)labelled (bio)molecules suitable mainly for medical applications. The aim of the invention is to provide novel prosthetic compounds or groups, the synthesis of which is straightforward, easy and automatable, enabling access to economical and effective, (radio)labelled, complex and fragile - especially water-soluble and more especially amine-containing- (bio)molecules. The aim is achieved by the invention, which involves precursors and compounds of respective formulae (Ip), (I). Said nucleophile-reactive sulfonated compounds are produced by pre-introduction of a nucleophilic compound R*, e.g. Fluorine- 18, through an unusal nucleophile-induced ring-opening reaction of the sultone (e.g. 1,3-propanesultone) moiety of the precursor. The invention also relates to the methods for producing the abovementioned precursors and compounds, as well as for the conjugation of these compounds with (bio)molecules, and to the drugs obtained through this method.
本发明涉及亲核反应性磺酸化合物,用作(放射性)标记的(生物)分子的前体物,主要适用于医学应用。本发明的目的是提供新型的假体化合物或基团,其合成简单、易于自动化,能够经济有效地获得(放射性)标记的、复杂和脆弱的(生物)分子,尤其是水溶性和胺基含量高的(生物)分子。本发明通过引入亲核化合物R*(例如氟-18)预先引入到前体物的磺酸酯环(例如1,3-丙烷磺酸酯)中,通过不寻常的亲核诱导的环开启反应来制备所述亲核反应性磺酸化合物。本发明还涉及制备上述前体物和化合物的方法,以及将这些化合物与(生物)分子结合的方法,以及通过该方法获得的药物。
