Synthesis of no-carrier-added [188, 189, 191Pt]cisplatin from a cyclotron produced 188, 189, 191PtCl4 2− complex
Abstract We developed a novel method for production of no-carrier-added (n.c.a.) [188, 189, 191Pt]PtIICl4 2− from an Ir target material, and then synthesized n.c.a. [*Pt]cis-[PtIICl2(NH3)2] ([*Pt]cisplatin) from [*Pt]PtIICl4 2−. [*Pt]PtIICl4 2− was prepared as a synthetic precursor of n.c.a. *Pt com...

| Sumario: | Abstract We developed a novel method for production of no-carrier-added (n.c.a.) [188, 189, 191Pt]PtIICl4 2− from an Ir target material, and then synthesized n.c.a. [*Pt]cis-[PtIICl2(NH3)2] ([*Pt]cisplatin) from [*Pt]PtIICl4 2−. [*Pt]PtIICl4 2− was prepared as a synthetic precursor of n.c.a. *Pt complex by a combination of resin extraction and anion-exchange chromatography after the selective reduction of IrIVCl6 2− with ascorbic acid. The ligand-substitution reaction of Cl with NH3 was promoted by treating n.c.a. [*Pt]PtIICl4 2− with excess NH3 and heating the reaction mixture, and n.c.a. [*Pt]cisplatin was successfully produced without employing precipitation routes. After this treatment, [*Pt]cisplatin was isolated through preparative HPLC with a radiochemical purity of 99 + % at the end of synthesis (EOS). |
