Definitions

  • the present invention relates to a novel opioid receptor antagonist derivative, a preparation method thereof, and a pharmaceutical composition containing the same, and a constipation, gastroesophageal reflux caused by long-term use of an opioid analgesic, Use in conditions such as bloating.
  • Opioid analgesics produce analgesic effects through the mu receptor acting on the central nervous system, which simultaneously acts on peripheral nerves in the gastrointestinal tract, increases non-propulsive contractions in the middle of the small intestine, and reduces the site's Longitudinal peristaltic contraction.
  • the longitudinal peristaltic contraction of the intestine is the key to the passage of food through the intestines, and the slowing of the gastrointestinal tract slows the passage of food through the digestive tract.
  • opioid analgesics can also cause local anesthesia of the stomach muscles, causing gastric muscle spasm and gastric emptying disorders, inhibition of secretion of gastrointestinal secretions, etc., causing gastrointestinal dysfunction, thereby causing constipation (Opioid-induced Constipation or OIC) ).
  • Gastrointestinal side effects not only affect the quality of life of the patient, but must even stop the administration of the drug in severe cases.
  • OIC opioid-induced constipation
  • Non-targeted therapeutic drugs are mainly divided into: gastrointestinal motility drugs and laxatives.
  • Prescription drugs for promoting gastrointestinal motility commonly used in patients with gastroparesis, suitable for short-term medication, and not suitable for young people, such drugs are prone to side effects such as restlessness, drowsiness and fatigue, and are CYP2D6 inhibitors.
  • a serotonin receptor agonist that acts throughout the gastrointestinal tract but is highly cardiotoxic.
  • Certain peripheral anti-dopamine agents reduce gastrointestinal dysfunction by increasing acetylcholine levels to enhance gastrointestinal smooth muscle contraction, tension and peristalsis.
  • Rubiprosone is a type II chloride channel activator that increases intestinal secretion and promotes intestinal smoothness for the treatment of sudden chronic constipation.
  • Oral laxatives including softeners and peristaltic inducers, however, the drug alone is not effective in treating gastrointestinal dysfunction caused by opioids, because the drug only softens the feces and does not enhance gastrointestinal motility.
  • the first-line drugs for the treatment of primary constipation have little effect in treating gastrointestinal dysfunction caused by opioids due to the above reasons, and have certain side effects.
  • Targeted therapy mainly uses ⁇ receptor antagonist drugs to act on the ⁇ receptor of the peripheral nerve of the intestine, relieves the agonistic effect of opioids on the ⁇ receptor, thereby restoring the function of the peripheral nerves of the intestine and restoring the gastrointestinal tract.
  • the peristaltic function of the road plays a role in curing constipation.
  • Low blood-brain barrier pass rate, low blood-brain barrier pass rate can ensure that the drug does not cross the blood-brain barrier, avoiding the drug acting on the central nervous system, thereby reducing the central nervous system mu receptor antagonism, affecting opioids The pain of the town.
  • Peripheral nerve has good affinity
  • ⁇ receptor antagonist drugs are peripheral nerve receptors. Good affinity can relieve the stimulating effects of opioids and fundamentally eliminate the root causes of gastrointestinal dysfunction.
  • the presently disclosed mu-receptor antagonists for the treatment of gastrointestinal dysfunction include US 6,559,158, US 2005 136 031, US 5,052, 542, WO 2006 126 529, WO 2004 026 305, WO 2007 103 187.

Abstract

本发明涉及阿片样受体拮抗剂类衍生物、其制备方法及其在医药上的应用。具体而言,本发明涉及一种通式(I)所示的纳洛酮类衍生物、其可药用盐,及其制备方法,以及它们作为治疗剂治疗因长期使用吗啡等阿片样受体激动剂而引起的便秘等疾病的用途,该药物作用于外周神经。其中通式(I)中的各取代基的定义与说明书中的定义相同。

Description

阿片样受体拮抗剂类衍生物、其制备方法及其在医药上的应用 技术领域
本发明涉及一种新型阿片样受体拮抗剂类衍生物、其制备方法及含有该衍生物的药物组合物,以及其在治疗因长期使用阿片类镇痛药引起的便秘、胃食管反流、腹胀等病症中的用途。
背景技术
阿片类镇痛药通过作用于中枢神经的μ受体产生镇痛作用,该类药同时作用胃肠道内的外周神经,增加小肠中部的非推动性收缩(non-propulsive contractions)并降低该部位的纵向性蠕动收缩。肠道的纵向性蠕动收缩是食物通过肠道的关键,胃肠道蠕动减慢使得食物很难通过消化道。此外阿片类镇痛药还可以局部麻醉胃肌,造成胃肌轻瘫和胃排空障碍、抑制胃肠道分泌液的分泌等造成胃肠道功能紊乱,从而引起便秘(Opioid-induced Constipation即OIC)。胃肠道副作用不仅影响病人的生活质量,严重时甚至必须停止给药治疗。
目前治疗阿片引起便秘(OIC)的方法主要有:非靶向性和靶向性疗法。
非靶向性疗法药物主要分为:促进胃肠道动力药物和通便剂。
促进胃肠道动力的处方药,常用于胃轻瘫患者,适宜短期用药,且不适用于年轻人群,该类药物容易产生不安、困倦和疲劳等副作用,而且是CYP2D6抑制剂。五羟色胺类受体激动剂,作用于整个胃肠道,但高心脏毒性较高。某些外周抗多巴胺剂,通过提升乙酰胆碱水平来增强胃肠道平滑肌的伸缩、张力和蠕动来减缓胃肠道功能紊乱。鲁比前列酮是II型氯离子通道活化剂,可以增加肠液分泌,促使肠道平滑,用于治疗突发性慢性便秘。
口服通便剂,包括软化剂和蠕动诱导剂,然而该药物单独用在治疗阿片类药物引起的胃肠道功能紊乱却没有疗效,因为该药物只能软化粪便,不能增强胃肠道蠕动能力。治疗正原发性便秘的一线药物由于上述同样原因在治疗阿片类药物引起的胃肠道功能紊乱中疗效甚微,并且具有一定的副作用。
靶向性疗法主要是利用μ受体拮抗剂类药物作用于肠道外周神经的μ受体,解除阿片样类药物对μ受体的激动作用,从而恢复肠道外周神经的作用,恢复胃肠道的蠕动功能,起到治愈便秘的作用。
治疗长期使用阿片类镇痛药引起的胃肠道功能紊乱的药物应该具备以下特征:
1)低的血脑屏障通过率,低的血脑屏障通过率可以保证药物不会穿过血脑屏障,避免药物作用中枢神经,从而降低药物中枢神经μ受体的拮抗作用,影响阿片类药物的镇疼作用。
2)对外周神经具有良好的亲和性,μ受体拮抗剂类药物对外周神经μ受体的 良好亲和性可以解除阿片类药物的激动作用,从根本上解除胃肠道功能紊乱产生的根源。
3)低毒性;4)良好耐受性;5)良好生物利用度;6)作用时间长效。
目前公开的用于治疗胃肠道功能紊乱的μ受体拮抗剂专利申请包括US6559158、US2005136031、US5250542、WO2006126529、WO2004026305、WO2007103187。
本发明致力于在靶向性治疗长期使用阿片类镇痛药引起的胃肠道功能紊乱领域取得一定的成果。

药代动力学评价
测试例5、本发明化合物在大鼠血脑屏障的通透性测试
以大鼠为受试动物,应用LC/MS/MS法测定大鼠血浆和脑组织中的药物浓度,研究本发明化合物在大鼠血脑屏障上的通透性,评价其进入中枢的能力。
SD大鼠(购自西普尔-必凯实验动物有限公司)32只,雌雄各半,平均分成8组;禁食一夜后分别灌胃本发明化合物(10mg/kg)和静脉注射纳洛酮(10mg/kg)。灌胃给药组于给药后2h采血后处死(采血量0.5ml),血样置于肝素化试管中,3500rpm离心10min分离血浆,于-20℃保存;处死后的动物断头,取脑组织,用滤纸吸干残留的血液,于液氮中速冻10min后于-20℃保存。静脉注射给药组于给药后15min取血后处死,操作方法同前。另取2只动物取空白血及脑,处理方法同给药组。
用LC/MS/MS法(质谱型号API4000,美国AB公司;液相系统型号LC-30AD,日本岛津公司)测定给药后大鼠血浆和脑组织中的药物浓度如下表5所示。
表5本发明化合物在大鼠血浆和脑组织中的浓度
Figure PCTCN2016107513-appb-000164
结论:本发明化合物透过大鼠血脑屏障的能力弱于对照药物,提示本发明化合物可以在改善肠蠕动的同时不会影响阿片类药物的镇痛活性。
测试例6、本发明化合物在小鼠和犬体内药代动力学测试
分别以小鼠和犬为受试动物,应用LC/MS/MS法测定了小鼠和犬灌胃给予本发明化合物后不同时刻血浆中的药物浓度。研究本发明的化合物在小鼠和犬体内的药代动力学行为,评价其药动学特征。
ICR小鼠(购自上海西普尔-必凯实验动物有限公司)72只,雌雄各半,平均分成6组;禁食一夜后分别灌胃给药。于给药前和给药后0.5、1、2、4、6、8、11、24h由眼眶采血0.1ml,置于肝素化试管中,3500rpm离心10分钟分离血浆,于-20℃保存;给药后2h进食。
Beagle犬(苏州西山中科药物研究开发有限公司提供)12只,雌雄各半,分成3组;禁食一夜后静脉注射给药。静脉组于给药前及给药后5分钟、0.25、0.5、1.0、2.0、4.0、8.0、12.0、24.0h,由前肢静脉采血1.0ml,置于肝素化试管中,3500rpm离心10分钟分离血浆,-20℃保存。给药后3h进食。
第二周期:Beagle犬清洗一周后,禁食一夜后灌胃给药。灌胃组于给药前及给药后0.5、1.0、2.0、3.0、4.0、6.0、8.0、12.0、24.0h,由前肢静脉采血1.0ml,置于肝素化试管中,3500rpm离心10分钟分离血浆,-20℃保存。给药后3h进食。用LC/MS/MS法(质谱型号API4000,美国AB公司;液相系统型号LC-30AD,日本岛津公司)测定灌胃给药后大鼠血浆中的待测化合物含量。
本发明化合物在小鼠和犬体内的药代动力学参数如下表6所示。
