present study was to transfer the concept of library screening by MS binding assays, so far applied to pseudostatic hydrazine libraries, to static oxime libraries to screen for new potent inhibitors of mGAT1, the most abundant GABA transporter in the central nervous system that represents a validated drug target for the treatment of epilepsy. Library generation was performed by reaction of guvacine derivatives
本研究的目的是将到目前为止已应用于假静态肼文库的MS结合测定法转移文库筛选的概念,转移至静态肟文库中以筛选新型强效抑制剂mGAT1,mGAT1是中枢神经系统中最丰富的GABA转运蛋白。代表治疗癫痫病的有效药物靶标。文库的产生是通过将具有羟胺官能度的番石榴碱衍生物与各种四种醛进行反应来进行的。稀释后,通过竞争性MS结合测定法筛选文库。解卷积实验可以识别最活跃的文库中的命中,然后将它们重新合成以进行生物学评估。这样,鉴定出一系列显示结合亲和力≥8.00(p Ki)在mGAT1,在功能性GABA吸收试验中,其中一种是迄今为止已知最有效的mGAT1抑制剂,pIC 50值为8.27±0.03。
