used in add-on therapy of epilepsy, are known to inhibit uptake of mGAT1 with high subtype selectivity and affinity. We synthesized new N-substituted nipecotic acid derivatives with a vinyl ether spacer and an unsymmetrical bis-aromatic residue, which carries fluorine substituents at various positions of the aromatic ring-system. The new compounds were characterized with respect to their potency and subtype
γ-氨基丁酸(GABA)是哺乳动物中枢神经系统(CNS)中的主要抑制性神经递质。GABA能神经传递的功能障碍与几种神经元疾病有关,例如癫痫,阿尔茨海默氏病,神经性疼痛和抑郁症。增强突触裂隙中GABA水平的一种可能性是抑制mGAT1,mGAT1是已知的四种与质膜结合的GABA转运蛋白之一,被认为是最重要的GABA转运蛋白亚型,它负责在GABA去除突触后裂隙中的GABA。神经冲动。众所周知,在癫痫的附加疗法中使用的批准的药物如尼加定的亲脂酸酸衍生物(Gagatrile®)具有很高的亚型选择性和亲和力,可抑制mGAT1的摄取。我们合成了具有乙烯基醚间隔基和不对称双芳族残基的新的N-取代的苯甲酸衍生物,该残基在芳族环系统的各个位置带有氟取代基。就它们作为mGAT1抑制剂的效力和亚型选择性而言,对新化合物进行了表征。
