resulting oximelibrary was screened accordingly toward the GABAtransporter subtype 1 (GAT1), a drug target for several neurological disorders. After assessing sublibraries’ activities for inhibition of reporter ligand binding, hits in active ones were directly identified. This could be achieved by recording mass transitions for the reporter ligand as well as those predicted for the library components
这项研究提出了一种有效的筛选方法,该方法基于基于质谱(MS)的结合测定(MS Binding Assays)和亲和力选择质谱(ASMS)的组合,这些筛查被定制用于筛选具有相同质谱碎片模式的结构均质文库。在具有羟胺官能团的乳酸衍生物与醛反应后,针对几种神经系统疾病的药物靶点GABA转运蛋白亚型1(GAT1)相应地筛选所得的肟库。在评估子图书馆抑制报告配体结合的活性后,直接鉴定出活性物质的命中。这可以通过在多反应监测模式下使用三重四极杆质谱仪运行的单个LC-MS / MS中记录报告配体的质量跃迁以及库组分的预测跃迁来实现。可以通过计算IC可靠地确定具有预定义亲和力的匹配来自文库成分和报道分子配体的特定结合浓度的50值。该策略的应用揭示了六个命中,其中两个命中被重新合成以进行进一步的生物学评估。因此,最好的一个在MS结合分析中显示出ap K i为7.38,在[ 3 H] GABA吸收分析中显示出pIC
