(TARPs) are a recently discovered family of proteins that modulate AMPA receptors activity. Based on a potent and selective TARP subtype γ-8 antagonist, 6-(methyl(4-(pyridin-2-yl)thiazol-2-yl)amino)benzo[d]thiazol-2(3H)-one (compound 9), we perform the radiosynthesis of its 11C-isotopologue 1 and conduct preliminary PET evaluation to test the feasibility of imaging TARP γ-8 dependent receptors in vivo
跨膜AMPA受体调节蛋白(TARP)是最近发现的可调节AMPA受体活性的蛋白家族。基于强效且选择性的TARP亚型γ-8拮抗剂,6-(甲基(4-(吡啶-2-基)噻唑-2-基)氨基)苯并[d]噻唑-2(3H)-(化合物9 ),我们进行了11C-同位素异构体1的放射性合成,并进行了初步的PET评估,以测试在体内成像TARPγ-8依赖性受体的可行性。
