class of nipecotic acid and guvacine derivatives has been synthesized and characterized for their inhibitory potency at mGAT1-4 and binding affinity for mGAT1. Compounds of the described class are defined by a four-carbon-atom allenyl spacer connecting the nitrogen atom of the nipecotic acid or guvacine head with an aromatic residue. Among the compounds investigated, the mixture of nipecotic acid derivatives
已经合成了一类新的乳酸酸和番石榴碱衍生物,并对其在mGAT1-4上的抑制力和对mGAT1的结合亲和力进行了表征。所述类别的化合物由连接碳酸盐或番石榴碱头部的氮原子与芳族残基的四碳原子的烯基间隔基定义。在所研究的化合物中,全脂酸衍生物rac-(Ra)-1- [4-([1,1':2',1''-三苯基] -2-yl)buta-2,3-二烯-1-基](3R)-哌啶-3-羧酸}和rac-(Sa)-1- [4-([1,1':2',1''-三苯基] -2-基)具有邻-叔苯基残基的()2,3-二烯-1-基](3R)-哌啶-3-羧酸}(buta-2,3-dien-1-yl)(3 p)被确定为高选择性且在本研究中最有效的mGAT1抑制剂。对于(R)-戊二酸衍生形式的21 p,在[3 H] GABA摄取测定中的抑制力确定为pIC 50 = 6.78±0.08,在MS结合测定中的结合亲和力确定为pKi = 7
