design and synthesis of a series of 2-substituted pyrrolidine-2-yl-acetic acid as core structures and the N-arylalkyl derivatives thereof as potential GABA transport inhibitors. The 2-position in the side chain of pyrrolidine-2-yl-acetic acid derivatives was substituted with alkyl, hydroxy and amino groups to modulate the activity and selectivity to mGAT1 and mGAT4 proteins. SAR studies of the compounds
在本文中,我们公开了一系列2-取代的吡咯烷-2-基-乙酸作为核心结构以及其N-芳基烷基衍生物作为潜在的GABA转运抑制剂的设计和合成。吡咯烷-2-基-乙酸衍生物的侧链中的2位被烷基,羟基和氨基取代,以调节对mGAT1和mGAT4蛋白的活性和选择性。对四种小鼠GABA转运蛋白(mGAT1-mGAT4)进行的化合物的SAR研究表明,对2-羟基-2-吡咯烷-2-基-乙酸衍生物具有显着的效力和亚型选择性。外消旋体rac-(u)-13c的效能最高(pIC 505.67)在GABA吸收试验中对mGAT1的选择性和mGAT1的选择性。实际上,的效力外消旋- (Û) - 13C在hGAT-1(PIC 50 6.14)比其在MGAT1效力更高。这些摄取结果外消旋- (Û) - 13C是符合结合亲和力到前述蛋白质MGAT1(对ķ我6.99)和hGAT-1(P ķ我7.18)由MS根据NO711作为标记结合测定
