其他信息

  • 用途二:早期用材林于抗眩晕和止吐药,目前作为神经系统药物,有促进和增强大脑记乙功能的作用,对老年性记忆减退有效。对某些低智能儿的智力提高胶,对老年性痴呆、脑外伤引起的记忆和思维障碍亦有一定疗效。
  • 下游产品:左乙拉西坦
  • 中枢神经兴奋药:吡拉西坦又称脑复康、吡乙酰胺、乙酰胺吡咯环酮,是一种脑代谢改善药物,属于γ-氨基丁酸的环化衍生物,对中枢作用选择性强,仅限于脑功能(记忆、意识等)的改善,精神兴奋作用弱,无精神药物的副作用,无依赖性。可预防或保护动物因缺氧而导致的逆行性健忘,亦能明显拮抗巴比妥盐对中枢的抑制作用,能促进脑细胞代谢,增加大脑对氨基酸、蛋白质、葡萄糖的吸收和利用,具有激活、保护和修复大脑神经细胞的作用,能促使脑内ADP转化为ATP,改善脑内代谢能量供应状况。它影响胆碱能神经元兴奋传递,促进乙酰胆碱合成。吡拉西坦可以抵抗物理因素和化学因素所致的脑功能损害,改善学习、记忆和回忆能力。可以改善由缺氧所造成的逆行性遗忘。口服易吸收,30~40分钟后血药浓度达峰值,蛋白结合率为30%,清除半衰期4~6小时,易透过血脑屏障,到达脑和脑脊液。口服后不能由肝脏分解,以原形形式从尿和粪便中排泄。主要用于脑部疾病所致的记忆和思维障碍,儿童器质性痴呆和智力低下,对轻中度的老年性痴呆有一定的作用,但对重症者无效。对改善功能性大脑功能衰退症候群的症状也有一定的疗效。吡拉西坦也可用于脑炎、一氧化碳、农药及酒精中毒的意识恢复,可用静注或滴注。

  • MOL 文件:7491-74-9.mol
  • 上游原料:甲醇钠 --> 氯乙酸乙酯 --> 氯乙酸甲酯 --> 2-吡咯烷酮
  • 用途一:用于脑动脉硬化症及脑血管意外所致的记忆和思维功能减退的治疗
  • 方法一:以2-吡咯烷酮为起始原料,在甲苯中与甲醇钠成盐,与氯代乙酸乙酯缩合后再氨化制得。
