distinctly improved chemical stability. (S)‐Nipecotic acid derivatives possessing a 2‐[1‐(4‐methoxy‐2‐methylphenyl)‐1,1‐bis(4‐methoxyphenyl)methoxy]ethyl (DDPM‐859) or a 4,4,4‐tris(4‐methoxyphenyl)but‐2‐en‐1‐yl moiety (DDPM‐1457) were found to exhibit pIC50 values of 5.78 and 5.87, respectively. Thus, as mGAT4 inhibitors, these compounds compare well with (S)‐SNAP‐5114 (pIC50=5.71), but are far more
一系列GABA吸收抑制剂,与已知最有效的mGAT4抑制剂(S)-1- 2- [三(4-甲氧基苯基)甲氧基]乙基}哌啶-3-羧酸[(S)-SNAP-5114]有关到目前为止,已经合成并对其在HEK-293细胞系中稳定表达的四种GABA摄取转运蛋白mGAT1-4的抑制力进行了生物学评估。开发了新的类似物,其效力类似于或略高于当前的mGAT4抑制剂,但具有明显改善的化学稳定性。(S)-拥有2- [1-(4-(甲氧基-2-甲基苯基)-1,1-双(4-甲氧基苯基)甲氧基]乙基(DDPM-859)或4,4,4-发现三(4-甲氧基苯基)but-2-en-1-基部分(DDPM-1457)的pIC 50值分别为5.78和5.87。因此,作为mGAT4抑制剂,这些化合物与(S)‐SNAP-5114(pIC 50 = 5.71)相比具有很好的对比,但比后者稳定得多。此外,与(S)‐SNAP‐5114相比,DD
