The role of the synaptic vesicle protein 2A (SV2A) protein, target of the antiepileptic drug levetiracetam, is still mostly unknown. Considering its potential to provide in vivo functional insights into the role of SV2A in epileptic patients, the development of an SV2A positron emission tomography (PET) tracer has been undertaken. Using a 3D pharmacophore model based on close analogues of levetiracetam
抗癫痫药左乙拉西坦的靶标突触小泡蛋白2A(SV2A)的作用仍是未知之数。考虑到其潜力,可以提供体内功能性洞察力,以了解SV2A在癫痫患者中的作用,目前已经开发了SV2A正电子发射断层扫描(PET)示踪剂。使用基于左乙拉西坦的紧密类似物的3D药效团模型,我们报告了三种杂环非乙酰胺前导化合物UCB‐A,UCB‐H和UCB‐J的原理设计,这是第一种具有合适性质的纳摩尔级SV2A配体发展为PET示踪剂。
