Vesicular monoamine transporter 2 (VMAT2) is essential for synaptic transmission of all biogenic amines in the brain including serotonin, norepinephrine, histamine, and dopamine (DA). Given its crucial role in the neurophysiology and pharmacology of the central nervous system, VMAT2 is recognized as an important therapeutic target for various neurological disorders such as tardive dyskinesia (TD).
囊泡单胺转运蛋白 2 (VMAT2) 对大脑中所有生物胺的突触传递至关重要,包括血清素、去甲肾上腺素、组胺和多巴胺 (DA)。鉴于其在中枢神经系统的神经生理学和药理学中的关键作用,VMAT2 被认为是迟发性运动障碍 (TD) 等各种神经系统疾病的重要治疗靶点。在这里,设计并合成了一系列新的二氢丁苯那嗪衍生物类似物,以评估它们对 [ 3 H] 二氢丁苯那嗪 (DTBZ) 结合和 VMAT2 处 [ 3 H]DA 摄取的影响。在这些类似物中,化合物13e对 VMAT2 显示出高结合亲和力(IC 50 = 5.13 ± 0.16 nM),对 [ 3H] DA 摄取 (IC 50 = 6.04 ± 0.03 nM) 在纹状体突触体中。在人肝微粒体中,13e 比其他报道的 VMAT2 抑制剂如 DTBZ (T 1/2 = 119.5 分钟)更稳定 (T 1/2 = 161.2分钟)。此外,13e有效抑制
