γ-Aminobutyric acid (GABA) neurotransmission has a significant impact on the proper functioning of the central nervous system. Numerous studies have indicated that inhibitors of the GABA transporters mGAT1-4 offer a promising strategy for the treatment of several neurological disorders, including epilepsy, neuropathic pain, and depression. Following our previous results, herein, we report the synthesis, biological
γ-氨基丁酸 (GABA) 神经传递对中枢神经系统的正常功能有重大影响。大量研究表明,GABA 转运蛋白 mGAT1-4 的抑制剂为治疗多种神经系统疾病提供了一种有前景的策略,包括癫痫、神经性疼痛和抑郁症。根据我们之前的结果,在此,我们报告了合成、生物学评价和构效关系研究,这些研究得到了一系列新的N-苄基-4-羟基丁酰胺衍生物的分子对接和分子动力学的支持,它们对 mGAT1-4 的抑制效力。这项研究使我们能够鉴定化合物23a ( N-benzyl-4-hydroxybutanamide 带有二苯并环庚三烯部分),一种非选择性 GAT 抑制剂,对 mGAT4 略有偏好(pIC 50 = 5.02 ± 0.11)和化合物24e(4-羟基-N -[(4-甲基苯基)-甲基]带有二苯并环庚二烯部分的丁酰胺)对 mGAT2 具有相对较高的抑制活性(pIC 50 = 5.34 ± 0.09)。在一组
