Definitions

  • This application relates to but not limited to the technical field of medicinal chemistry, in particular to a quaternary ammonium salt compound and its preparation method and application.
  • Local anesthetics also known as local anesthetics
  • local anesthetics are a class of drugs that are applied locally around the nerve trunk or nerve endings, which can temporarily, completely and reversibly block the generation and conduction of nerve impulses, and temporarily disappear the local pain sensation.
  • the mechanism of action of local anesthetics is to bind to the binding site of the sodium channel on the nerve cell membrane, reduce the influx of Na + in the cell membrane, change the membrane potential, thereby preventing the conduction of nerve impulses to achieve anesthetic effect. Due to the advantages of definite effect, less hyperalgesia, convenient topical application, low blood drug concentration and less systemic side effects, local anesthetics are still widely used in clinical pain treatment.
  • the local anesthetics currently used clinically are mainly a class of compounds in which the aromatic group and the amine group are linked by an ester bond or an amide bond, such as procaine, tetracaine, lidocaine, bupivacaine and ropivaca because.

一种季胺盐化合物及其制备方法和用途
相关申请
本申请要求2021年05月27日提交的、发明名称为“一种季胺盐化合物及其制备方法和用途”、申请号为CN202110587550.8的中国发明专利申请的优先权权益,该中国专利申请的全部内容通过引用并入本文。
技术领域
本申请涉及但不限于药物化学技术领域,尤其涉及一种季胺盐化合物及其制备方法与用途。
背景技术
局部麻醉药(local anaesthetics)又称为局麻药,是一类局部应用于神经干或神经末梢周围,能暂时、完全和可逆地阻断神经冲动的产生和传导,使局部的痛觉暂时消失的药物。局麻药的作用机制是通过与位于神经细胞膜上钠通道的结合位点结合,减少细胞膜Na +内流,改变膜电位,从而阻止神经冲动的传导而实现麻醉效果。由于具有效果确切、不易出现痛觉过敏、局部用药方便、血药浓度低和全身副作用少等优点,局麻药仍是临床上使用得较多的一种疼痛治疗手段。
目前临床上使用的局麻药主要是芳香基和胺基通过酯键或酰胺键连接而成的一类化合物,如普鲁卡因、丁卡因、利多卡因、布比卡因和罗哌卡因。虽然其中布比卡因和罗哌卡因被认为是新型的长效局麻药,但它们单次给药的镇痛时间通常不超过8h(“Local anesthetics:review of pharmacological considerations”,Becker D E.et al.,Anesth Prog.2012,59(2):90-102.),虽然可以满足大部分手术或有创操作,但远远不能完全满足术后疼痛、慢性疼痛等需要。
利多卡因的季铵盐衍生物QX-314,虽然穿过细胞膜后可以有效地阻滞钠离子电流,产生较持久的麻醉作用,但因其永久带正电荷,所以较难主动透过脂溶性细胞膜(“Mechanism of frequency-dependent inhibition of sodium currents in frog myelinated nerve by the lidocaine derivative GEA”,Courtney KR. J Pharmacol Exp Ther.1975,195:225-236)。研究显示QX-314与局部麻醉剂或瞬时受体通道(TRP)激动剂联用可以透过细胞膜,产生长时效的局部麻醉效果,但是会导致局部神经毒性及全身毒性增加(“Anti-nociceptive and desensitizing effects of olvanil on capsaicin-induced thermal hyperalgesia in the rat”,Alsalem M.et al.,BMC Pharmacol Toxicol.2016,17(1):31.)。

测试例1、本申请化合物的神经阻滞局部麻醉效果
选取实施例化合物、盐酸左布比卡因阳性对照组分别给予3组完全适应环境的大鼠,每组1只。
溶液配制:2mg/mL盐酸左布比卡因注射液:移液枪吸取2.670mL 7.5mg/mL盐酸左布比卡因注射液(批号:92S0702)加入到10mL容量瓶中,加入0.9%NaCl溶液至凹液面与刻度线齐平,颠倒混匀,配置成2mg/mL的盐酸左布比卡因注射液。6mg/mL(按实施例化合物的分子量计算出摩尔浓度范围为:8.6-10.1mmol/L)实施例化合物溶液:准确称取19.80mg实施例化合物加入3.3mL 0.9%NaCl溶液配置成6mg/mL的实施例化合物溶液。
每只大鼠的给药或对照注射5mL/Kg,采用单次右侧坐骨神经给药,将给药后大鼠放置于预热的50±0.1℃的智能热板仪的热板上,记录大鼠给药一侧出现明显抬足、舔足等规避热刺激的行为现象时所需的时间记为热潜伏期。热潜伏期允许的最大值控制在60s,若在60s后大鼠仍无舔足现象,则手动将大鼠的后足抬起,避免组织损伤或痛觉过敏等现象的发生,并将60s作为该大鼠的热潜伏期。在每次测量后及时对热板上可能存在的尿液和粪便进行擦拭并晾干以便后续测试。
分析方法
热潜伏期的结果用最大比例效应(Maximum proportionality effect,MPE)表示,使用以下方程进行计算:
MPE(%)=(C-B)/(P-B)*100%
其中,B代表大鼠的基础热潜伏期,P代表允许的最大热潜伏期,C代表检测时间点的热潜伏期。
规定测定时间低于50%最大比例效应判定为无效,连续测定两次均低于50%最大比例效应后停止测定。

实验结果表明,本申请化合物在浓度为6mg/mL(折合摩尔浓度范围为8.6-10.1mmol/L)时,在大鼠皮下浸润模型中能够产生大于48小时的局部麻醉作用,并起效快。其中部分化合物能产生大于72小时的局部麻醉作用,起效时间为1min。
由于局麻时间长于72小时有可能导致不可逆的神经损伤,因此后续我们将作用时间大于72小时的化合物剂量减半(3mg/mL)后进行了活性测试,以确定是否在皮肤浸润模型的局麻效果可以恢复。
