Definitions

  • the invention belongs to the field of chemistry and medicine, and specifically relates to benzodiazepine compounds, preparation methods thereof, and medical effects.
  • Midazolam is the most commonly used benzodiazepine, with good safety, mainly by binding to the central gamma-aminobutyric acid (GABAA) receptors.
  • GABAA central gamma-aminobutyric acid
  • the onset is relatively rapid, and it has the effect of reducing intracranial pressure and brain metabolism. It is often used for pre-anaesthesia administration, general anesthesia induction and maintenance, intraspinal anesthesia and auxiliary medication during local anesthesia, diagnostic or therapeutic procedures such as cardiovascular imaging, Cardiac cardioversion, bronchoscopy, gastrointestinal endoscopy, etc., ICU patients are sedated.
  • Remimazolam's parent structure is midazolam, which is an ultra-short-acting intravenous benzodiazepine sedative/anaesthetic that acts on GABA receptors, especially GABA- ⁇ .
  • the drug combines the safety of midazolam with the effectiveness of propofol (propofol).
  • Remimazolam is rapidly metabolized by tissue esterase into inactive metabolites and is not affected by cytochrome-dependent liver pathways. Metabolism is an ultra-short-acting benzodiazepine.
  • As an intravenous general anesthetic it has the characteristics of fast onset, short duration, quick recovery and good tolerance.
  • Remazolam is used for anesthesia induction, anesthesia maintenance and day surgery anesthesia. Compared with other products, it has certain advantages when applied to patients with cardiovascular diseases, respiratory diseases, liver diseases and elderly patients.

Description

苯二氮卓类化合物及其制备方法和在医药上的作用 技术领域
本发明属于化学医药领域,具体涉及苯二氮卓类化合物及其制备方法和在医药上的作用。
背景技术
咪达唑仑是最常用的苯二氮卓类药,安全性较好,主要是通过结合中枢γ-氨基丁酸(GABAA)受体而发挥作用。起效较为迅速,具有降低颅内压以及脑代谢的作用,常用于麻醉前给药、全麻醉诱导和维持、椎管内麻醉及局部麻醉时辅助用药、诊断或治疗性操作如心血管造影、心律转复、支气管镜检查、消化道内镜检查等时、ICU病人镇静。但由于其代谢依赖于肝脏及肾脏,长时间持续输注会造成药物在体内蓄积,通常出现过度镇静、呼吸循环抑制、药物耐受等不良反应,并且对于肝肾功能障碍患者不能长时间使用。
瑞马唑仑(Remimazolam)的母体结构是咪达唑仑,是一种超短效静脉注射苯二氮卓镇静剂/麻醉剂,作用于GABA受体,特别是GABA-α。该药结合了咪达唑仑的安全性与异丙酚(丙泊酚)的有效性,在人体中,Remimazolam被组织酯酶迅速代谢成无活性代谢物,并且不被细胞色素依赖性肝脏途径代谢,是一种超短效苯二氮卓类药物,其作为静脉全身麻醉药物,具有起效快、持续时间短、苏醒快和耐受性良好的特点。瑞马唑仑用于麻醉诱导、麻醉维持和日间手术麻醉,相比其他产品在应用于伴有心血管疾病、呼吸系统疾病、肝病以及老年患者时具有一定的优势。
但相关报道瑞马唑仑相比其他镇静药物效价较低,临床应用时需提高用药剂量,增加潜在的毒性;同时瑞马唑仑的游离碱结构不稳定,副产物具有相当的毒性,并会进一步影响体内药物代谢酶活性,造成持续用药时血药浓度偏高和药物蓄积等问题。因此期望开发出安全性更好、效价更高的新型超短效镇静麻醉类药物。

以下通过具体的试验例证明本发明化合物的有益效果。
对本发明化合物8~84进行药理活性、药效以及安全性评价。
在临床应用中,需要对麻醉药物的作用进行严格把控,从而保证在手术、诊断等过程顺利进行,并且在操作结束后可以尽快终止麻醉,让病人快速苏醒。如果麻醉持续时间过长,可能会造成对心血管系统和呼吸系统一些不良影响,例如嗜睡、头晕等。因此理想的麻醉药物应该具有起效快、恢复快、安全性高等优点。
