paper, we report the synthesis and biological evaluation of a series of 1,5- and 1,4- substituted derivatives of 1H-imidazol-4-ylacetic acid, a series of 1,2-substituted 3-(1H-imidazol-2-yl)propanoic acid and an N-substituted (2E)-3-(1H-imidazol-2-yl)prop-2-enoic acid as new mGAT3 inhibitors. The lipophilic moieties attached to the N-atom of the parent structures were delineated from the 2-[9-(4-metho
在本文中,我们报道了一系列1 H-咪唑-4-基乙酸的1,5和1,4-取代衍生物,一系列1,2-取代3-(1 H -咪唑-2-基)丙酸和N-取代的(2 E)-3-(1 H-咪唑-2-基)丙-2-烯酸作为新的mGAT3抑制剂。附接至所述亲脂部分Ñ母体结构-原子是从2-划定[9-(4-甲氧基苯基)-9- ħ芴-9-基]氧基乙基残基,从原型MGAT3抑制剂是已知的。对于结构活性关系研究,咪唑环的N原子与2- [9-(4-甲氧基苯基)-9之间的间隔基H-芴-9-基]部分的长度在3至6个原子之间变化,并且本质上是纯的饱和或不饱和的烷基链或含有至多两个醚官能团的烷基链。表征了该化合物对小鼠GABA转运蛋白mGAT1–mGAT4的抑制作用。在1,2-取代的化合物中,包含C 5 O间隔基的N-烷基化的(2 E)-3-(1 H-咪唑-2-基)丙-2-烯酸12e的pIC 50值为5.13在mGAT3处为±0.0
