9-甲基-β-咔啉英语:9-Methyl-β-carboline,简称9-Me-BC)是β-咔啉家族的杂环胺,是一种研究性化学物质[1]

化学[编辑]

9-Me-BC是β-咔啉甲基化衍生物,分子式为C12H10N2

它可以通过对游离碱β-咔啉(去甲哈尔满)进行埃施魏勒-克拉克反应来制备[來源請求]

生物效应[编辑]

多巴胺能神经元细胞培养物体外研究表明,在长期给予鱼藤酮后,酪氨酸羟化酶和相关转录因子的表达增加,神经突生长增加,神经元再生,炎症细胞因子的表达减少。[2]在原代中脑多巴胺能神经元细胞培养物的研究中,该物质增加了分化的多巴胺能神经元的数量,并产生了更高水平的与多巴胺能分化相关的转录因子。[3]9-甲基-β-咔啉还在体外抑制神经毒素前体MPTP向多巴胺能神经毒素MPP+的氧化过程。[4]

啮齿动物体内研究表明,海马体多巴胺水平升高,径向臂迷宫英语Radial arm maze测试中的空间学习表现得到改善,并且海马齿状回树突生长增加,[5]帕金森病动物模型中,左侧表达酪氨酸羟化酶的神经元数量恢复,而注射MPP+纹状体中此类细胞的数量减少了50%。[6]

9-甲基-β-咔啉是一种已知的单胺氧化酶A单胺氧化酶B抑制剂,并已被提议在帕金森病的治疗中进行进一步研究。[7]

它可能具有光敏作用[8]
