在这项研究中,我们设计并评估了一种新的α-黑素细胞刺激激素衍生物与四个N-甲基化黑皮质素1受体靶向黑色素瘤成像与正电子发射断层扫描(PET)。所得肽DOTA-Pip-Nle 4-Cyclo[Asp 5-N-Me-His 6-d-Phe 7-N-Me-Arg 8-N-Me-Trp 9-N-Me-Lys 10]α MSH 4 -10-NH 2(CCZ 01099)显示出高受体选择性、极大改善的稳定性和快速内化。[68 Ga] Ga-CCZ 01099在临床前黑色素瘤模型中显示出清晰的肿瘤可视化和良好的肿瘤与正常组织的PET成像对比度。因此,CCZ 01099是一种有前途的化合物,用于成像和潜在的放射性配体治疗黑色素瘤。
In this study, we designed and evaluated a novel α-melanocyte-stimulating hormone derivative with four N-methylations for melanocortin 1 receptor-targeted melanoma imaging with positron emission tomography (PET). The resulting peptide, DOTA-Pip-Nle4-Cyclo[Asp5-N-Me-His6-d-Phe7-N-Me-Arg8-N-Me-Trp9-N-Me-Lys10]αMSH4-10-NH2 (CCZ01099), showed high receptor selectivity, greatly improved stability, and rapid internalization. [68Ga]Ga-CCZ01099 showed clear tumor visualization and excellent tumor-to-normal tissue contrast with PET imaging in a preclinical melanoma model. Therefore, CCZ01099 is a promising compound for imaging and potentially radioligand therapy for melanoma.
