制备方法与用途

盐酸乙哌立松 概述

盐酸乙哌立松，又名妙纳、艾派瑞松，是一种β-氨基酮类中枢性肌肉松弛药。化学名为4'-乙基-2-甲基-3-(1-呱啶基)苯丙酮盐酸盐，于1983年首次在日本上市，商品名为Myonal。它主要作用于中枢神经系统及血管平滑肌，能够抑制动物实验性强直、扩张血管、改善血液循环、抗眩晕以及镇痛，并能使脑血管意外患者顺利进行随意运动。临床上主要用于改善颈肩臂综合征、肩周炎、腰痛症等疾病引起的肌肉紧张状态和改善脑血管障碍、痉挛性脊髓麻痹、颈椎病、手术后遗症、肌萎缩性侧索硬化症、婴儿脑瘫痪、脊髓小脑变性、脊髓血管障碍、亚急性视神经脊髓病及其他脑脊髓疾病引起的痉挛性麻痹。

制备方法

采用对乙基苯丙酮(2)与盐酸呱陡经Mannieh反应后成盐合成本品，具体路线如图1所示。

合成步骤：

1. 对乙基苯丙酮(2)的合成：投料丙酞氯（100g, 1.08 mol），经处理后的反应液回收石油醚及多余乙苯后减压蒸馏，收集bP112-114 ℃/1.33kPa馏分，得2。

2. 盐酸乙哌立松(1)的合成：取新蒸馏呱陡（20.2g, 0.24 mol），加入无水乙醇（20 ml），于低温下滴加浓盐酸至pH 4-5，减压蒸去乙醇后加入无水乙醇（50 ml）、对乙基苯丙酮（32.4g, 0.2mol）、36%甲醛溶液（42.0g, 0.5mol）及浓盐酸（1ml），搅拌回流8h 蒸去溶剂，残留物溶于10 %氢氧化钠溶液中，乙醚提取，提液水洗、干燥后，在冰水浴下通入氯化氢至pH 2-3。滤出生成的固体，用乙醇一丙酮重结晶得盐酸乙哌立松。

药理作用 主要作用

盐酸乙哌立松能有效抑制中枢神经系统和血管平滑肌的强直反应，并且扩张血管、改善血液循环、抗眩晕以及镇痛。它还能帮助脑血管意外患者恢复随意运动功能。

临床应用

临床上主要用于治疗颈肩臂综合征、肩周炎、腰痛症等导致肌肉紧张的疾病，同时也用于治疗脑血管障碍、痉挛性脊髓麻痹、颈椎病、手术后遗症、肌萎缩性侧索硬化症、婴儿脑瘫痪、小脑变性和血管病变引起的痉挛症状。

剂量与用法

盐酸乙哌立松的剂量和使用方法应严格遵循医嘱。饭后服用，注意观察有无不良反应出现。具体用药期间可能会出现乏力、头昏或嗜睡等症状时，应立即停药或减量，并禁止驾驶或操作机械。

给药护理要点

1. 按肌肉松弛药护理总则进行。
2. 饭后服用。
3. 开封后防潮保存。
4. 观察有无下列不良反应：肝、肾功能异常，红细胞计数和血红蛋白值异常时应停止用药。皮疹、瘙痒、失眠、头痛、四肢僵硬、麻木，胃部不适、便秘或腹泻，腹痛、腹胀感等。

  Mannich reaction of ketones using 1, 3-dioxolane instead of formaldehyde, paraformaldehyde, or 1, 3, 5-trioxane afforded the corresponding Mannich bases in high yields. Under the same conditions the aminomethylation of aromatics did not proceed but the intramolecular aminomethylation, like a Pictet-Spengler type reaction, proceeded smoothly.

  Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs may have surfaces that include functional groups that are complementary to surface sites of targets such as nanostructures or macromolecular targets, and may be capable of specifically interacting with such targets. The positions of the functional groups in one embodiment are stabilized by a polymer network. The SPCs are formed by contacting the target with a set of monomers which self-assemble on the target, and then are polymerized into a network to form the synthetic polymer complement. At least a portion of the surface of the resulting SPC thus may include an imprint of the target. The complex of the SPC and the target may be the desired product. Alternatively, the target is released, for example, by controllably expanding and contracting the crosslinked network. The SPC is isolated and used in many applications.
