Synthesis and biological evaluation of PET tracers designed for imaging of calcium activated potassium channel 3.1 (K<sub>Ca</sub>3.1) channels <i>in vivo</i>
Ca2+ activatedpotassiumchannel3.1 (KCa3.1) channel (also known as the Gàrdos channel) is dysregulated in many tumor entities and has predictive power with respect to patient survival. Therefore, a positronemissiontomography (PET) tracer targeting this ion channel could serve as a potential diagnostic tool by imaging the KCa3.1 channel in vivo. It was envisaged to synthesize [18F]senicapoc ([18F]1)
Ca 2+激活的钾通道 3.1 (K Ca 3.1) 通道(也称为 Gàrdos 通道)在许多肿瘤实体中的表达失调,并且对患者的生存具有预测能力。因此,针对该离子通道的正电子发射断层扫描 (PET) 示踪剂可以通过在体内对 K Ca 3.1 通道进行成像来作为潜在的诊断工具。设想合成[ 18 F] senicapoc ([ 18 F] 1 ),因为senicapoc ( 1 ) 对K Ca 3.1 通道显示出高亲和力和优异的选择性。由于在18 F-氟化过程中出现问题,[合成18 F]fluoroethoxy senicapoc 衍生物 [ 18 F] 28以生成另一种靶向 K Ca 3.1 通道的 PET 示踪剂。膜片钳实验证实了28对 K Ca 3.1 通道的28显示在小鼠和人血清中的体外稳定性。此外,在野生型小鼠中进行了生物分布实验。由于在施用[ 18 F] 28后在体内检测到[ 18
