tracers, such as fluorine-18-labeled MMP inhibitors (MMPIs). Therefore, fluorinated dibenzofuransulfonamide-based MMPIs showing excellent inhibition of MMP-12 and selectivity for MMP-12 over other MMPs were prepared. MMP-12 is a key enzyme in diseases such as chronic obstructive pulmonary disease (COPD) and atherosclerosis. Because of their promising in vitro properties, three candidates (4, 9, and
活化基质金属蛋白酶(MMPs)的水平失调与不同的病状相关,例如癌症,动脉粥样硬化,神经炎症和关节炎。因此,用正电子发射断层扫描(PET)对MMP进行成像是诊断MMP相关疾病的有力工具。此外,为了区分单个MMP在特定病理生理过程中的独特功能和作用,必须使用放射性标记的示踪剂(例如氟18标记的MMP抑制剂(MMPI))来实现其特定的成像。因此,制备了氟化的基于二苯并呋喃磺酰胺的MMPI,其显示出对MMP-12的优异抑制作用以及对MMP-12的选择性,其优于其他MMP。MMP-12是慢性阻塞性肺疾病(COPD)和动脉粥样硬化等疾病中的关键酶。4,9和19)从该库中选择,和放射氟化类似物([ 18 F] 4,[ 18 F] 9,和[ 18 F] 19)成功地合成。初步的体外血清稳定性和放射性标记的MMPIs与PET的体内生物分布研究表明,它们对于优选的MMP-12成像具有潜在的好处。
