摘要
多模式成像剂最初在十年前被介绍,它具有放射和荧光对比双示踪的靶点基团。这些化合物可以用于单一药剂执行的全身和手术中成像,并能提供指导肿瘤切除的互补性诊断信息。初步评价以后,双重示踪剂越来越受关注,并且随着新螯合剂、改良荧光物质和用于形成生物共轭体的高选择性偶联技术等的开发,其设计也在进步。本文讨论了标记成分和方案为多模式药剂开发做出的改变对成像性能的影响,并着重讲述了作为双标记模型的基于抗体和肽的药剂。我们也讲述了模块化双标记策略和使用放射性卤素直接标记法越来越大的作用。

摘要: Multimodal imaging agents were first introduced a decade ago and consist of a targeting moiety that is dual-labeled with radioactive and fluorescent contrast. These compounds allow whole-body and intraoperative imaging to be performed through administration of a single agent and provide complementary diagnostic information that can be used to guide tumor resection. Since their initial evaluation, interest in dual-labeled agents has continued to grow and their design has subsequently evolved alongside the development of novel chelating agents, improved fluorophores, and highly selective coupling techniques for bioconjugate formation. In this review, will discuss how changes in the labeling components and schemes for multimodal agent development have impacted imaging performance and will focus on antibody- and peptide-based agents as models for dual labeling. We will also describe the growing role of modular dual labeling strategies as well as direct labeling methods using radiohalogens.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
