In this communication, we describe the successful encapsulation of (177)Lu into the endohedral metallofullerene (177)Lu(x)Lu(3-x)N@C(80) (x = 1-3) starting with (177)LuCl(3) in a modified quartz Kraschmer-Huffman electric generator. We demonstrate that the (177)Lu (beta-emitter) in this fullerene cage is not significantly released for a period of up to at least one-half-life (6.7 days). We also demonstrate that this agent can be conjugated with an interleukin-13 peptide that is designed to target an overexpressed receptor in glioblastoma multiforme tumors. This nanoparticle delivery platform provides flexibility for a wide range of radiotherapeutic and radiodiagnostic multimodal applications.
在本通讯中,我们描述了(177)Lu 在内笼金属富勒烯(177)Lu(x)Lu(3-x)N@C(80)(x = 1-3)中的成功封装,起始物质为(177)LuCl(3),使用改良的石英 Kraschmer-Huffman 发电机。我们证明,在长达至少一半半衰期(6.7 天)的时间内,笼内的(177)Lu(β发射器)不会明显释放。我们还证明,该试剂可以与白介素-13 肽缀合,后者旨在靶向多形性胶质母细胞瘤中过表达的受体。这种纳米颗粒递药平台为广泛的放射治疗和放射诊断多模态应用提供了灵活性。
