制备方法与用途

生物活性

Pentetreotide 是 Octreotide 的 DTPA 共轭物，是一种铟标记的生长抑素类似物，用于核医学成像。它能有效观察神经内分泌肿瘤及其转移。

体外研究

神经内分泌肿瘤相比正常组织具有更多的生长抑素受体，目前已知有五种亚型。使用 111In-Pentetreotide 进行生长抑素受体闪烁显影可结合两种亚型，并能有效可视化神经内分泌肿瘤及其转移，整体诊断敏感性在 70% 至 90% 之间。与传统解剖成像相比，其灵敏度显著更高。该技术不仅用于评估疾病范围，还能帮助识别原发病灶、评估治疗反应及选择核素疗法。

  Concise site-specific synthesis of DTPA–peptide conjugates: Application to imaging probes for the chemokine receptor CXCR4

  摘要：

  Diethylenetriaminepentaacetic acid (DTPA) is a useful chelating agent for radionuclides such as (68)Ga, (99m)Tc and (111)In, which are applicable to nuclear medicine imaging. In this study, we established a facile synthetic protocol for the production of mono-DTPA-conjugated peptide probes. A novel monoreactive DTPA precursor reagent was synthesized in two steps using the chemistry of the o-nitrobenzenesulfonyl (Ns) protecting group, and under mild conditions this DTPA precursor was incorporated onto an N(epsilon)-bromoacetylated Lys of a protected peptide resin. The site-specific DTPA conjugation was facilitated by using a highly acid-labile 4-methyltrityl (Mtt) protecting group for the target site of the bioactive peptide during the solid-phase synthesis. A combination of both techniques yielded peptides with disulfide bonds, such as octreotide and polyphemusin II-derived CXCR4 antagonists. DTPA-peptide conjugates were purified in a single step following cleavage from the resin and disulfide bond formation. This site-specific on-resin construction strategy was used for the design and synthesis of a novel In-DTPA-labeled CXCR4 antagonist, which exhibited highly potent inhibitory activity against SDF-1-CXCR4 binding.
