Description
技术领域
本发明属于医药化学领域,具体涉及一种兼具长效局部麻醉和选择性局部麻醉作用的酰胺类季铵盐衍生物及其制备方法和用途。
背景技术
局部麻醉药(Local anesthetics,简称局麻药)是一类能在用药局部可逆性的阻断感觉神经冲动发生与传递的药品。它是一种在动物或人意识清醒的条件下,在局部可逆的阻断感觉神经冲动产生与信号传导,使有关神经支配的部位出现暂时性感觉丧失,从而可逆的引起局部组织痛觉消失的一类药物。一般的,局麻药的作用局限于给药部位并随药物从给药部位扩散而迅速消失。局部麻醉药通过直接抑制神经细胞和纤维膜上的相关离子通道,阻滞动作电位的产生和神经冲动的传导,从而产生局部麻醉作用。目前公认的局麻药作用机制,是阻断神经细胞膜上的电压门控性Na+通道,使神经冲动传导阻滞,从而产生局部麻醉作用。
临床目前所使用的局麻药均为不带电荷的疏水性化合物,因此容易通过扩散和渗透方式穿透细胞膜进入神经细胞达到钠通道的阻断位点。这些麻醉药阻断钠通道从而阻断神经元的兴奋性。但是,这些局部麻醉药分子虽然容易通过扩散进入神经细胞内发挥作用,但同时也容易通过扩散作用从给药部位迅速扩散,游离出神经细胞,导致局部麻醉作用无法长时间持续。即使加大使用剂量也只能在一定程度内延长局部麻醉时间,无法获得理想的长时间局部麻醉作用。目前临床常用的局部麻醉药物作用时间大多不超过4小时。由于传统局部麻醉药的作用维持时间较短,不得不使用镇痛泵来维持神经阻滞,采取椎管内、神经根、皮下等部位的置管,大大增加了医疗成本和感染的发生率。
另一方面,传统局部麻醉药物对神经的阻滞并不具有特异的选择性,在使用过程中广泛地阻滞多种神经纤维,影响感觉、痛觉、运动以及交感神经等多种神经功能,这一药理特点极大的限制了局部麻醉药在临床中的广泛应用。例如膝关节置换术后患者早期的功能锻炼对康复尤为重要,但是目前临床使用的局麻药中并无选择性阻滞痛觉的药物,大部分手术患者由于使用局部麻醉药导致运动神经被阻滞,无法恢复运动功能,从而使得术后康复受限。局部麻醉药研究急需引入新的研究思路,开发选择性阻滞感觉功能而不影响运动功能的长效局部麻醉药物以满足临床需求。

实验例2、本发明化合物在大鼠皮下浸润模型中的局部麻醉效果的研究
(1)实验方法
250~300克体重的大鼠背部剃毛消毒后,在裸露的背部一侧画出直径约1.5厘米圆形,并将圆形进行6等分。在中心的皮肤处皮下分别注射含有本发明化合物1-8、21-31或盐酸左布比卡因的溶液0.5mL(均以水为溶剂,盐酸左布比卡因浓度为23mmol/L,本发明化合物1-8、21-31浓度为6mmol/L)。将Von Frey纤维丝中100克力度的纤维丝与针头绑定进行皮肤局部刺激。药物射5min后,使用上述方法在6个划分范围内进行刺激,若在同一等分范围内的连续3次刺激均未出现背部皮肤收缩行为,视为药效效应阳性,若出现背部皮肤收缩则视为局部麻醉效应消失。6个等分范围中有3个或3个以上区域显示局部麻醉阳性,则视为药物的局部麻醉有效,6个等分范围中少于3个区域显示阳性,视为局部麻醉失效。每种药物使用10只大鼠进行实验。
(2)实验结果
表2本发明化合物的皮下浸润局部麻醉效果
实验结果表明,本发明化合物1-8、21-31在大鼠皮下浸润模型中起效快,能够产生35小时以上的局部麻醉作用。
