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...
