Abstract
本发明涉及(S)‑2‑(6‑氟苯并[d]噁唑‑2‑基)‑6‑甲氧基‑5‑((5‑甲氧基吡啶‑2‑基)甲氧基)‑1,2,3,4‑四氢异喹啉‑3‑甲酸可药用的盐、其制备方法、包含该可药用的盐的药物组合物以及其作为治疗剂特别是作为血管紧张素Ⅱ2型受体拮抗剂的用途。
Description
技术领域
本发明涉及(S)-2-(6-氟苯并[d]噁唑-2-基)-6-甲氧基-5-((5-甲氧基吡啶-2-基)甲氧基)-1,2,3,4-四氢异喹啉-3-甲酸的可药用的盐的形式、其制备方法、包含该可药用的盐的药物组合物以及其作为治疗剂特别是作为血管紧张素Ⅱ2型受体拮抗剂的用途。
背景技术
神经性疼痛是由神经系统出现原发性损伤或功能障碍引起的慢性疼痛疾病,按病变的部位可分为外周神经性疼痛和中枢神经性疼痛。外伤、炎症、感染或压迫等原因均可引起神经性疼痛,例如糖尿病性神经痛(DNP)、带状疱疹后遗神经痛(PHN)、原发性神经病、继发性神经病、周围神经病、由机械性神经损伤或生化神经损伤引起的神经病疾病等。目前临床上用于治疗神经性疼痛的药物主要有抗癫痫药物、抗抑郁药物和麻醉性镇痛药,如加巴喷丁、普瑞巴林、三环类抗抑郁药等。但这些药物没有针对性,治疗效果非常有限,而且有严重的副作用,包括认知改变、镇静作用、恶心以及耐受性和依赖性,远未满足临床用药需求。因此,需要研究神经性疼痛的发病机制、找到药物作用明确的靶点,开发新型的能有效治疗神经性疼痛且不良反应少的药物。
血管紧张素Ⅱ受体是以血管紧张素Ⅱ作为配体的G蛋白偶联受体,它是肾素-血管紧张素系统的重要组成部分。血管紧张素Ⅱ受体主要亚型包括1型受体(AT1R)和2型受体(AT2R)。AT1R和AT2R仅有约30%的氨基酸序列相同,但血管紧张素Ⅱ作为其主要配体,与二者有相近的亲和力。
AT1R是被研究得最清楚的血管紧张素受体。AT1R受体激活可引起平滑肌收缩、醛固酮和加压素分泌、肾小管重吸收钠增加、中枢和外周交感神经激活以及心肌肥厚等,因此,在受体水平上拮抗血管紧张素Ⅱ成为寻找新型降压药物的研究热点,并由此诞生一系列沙坦类降压药物。
AT2R在各种胚胎组织中大量表达,在成年正常组织中分布较少,但是在组织损伤后,其表达升高。AT2R与血压调控、神经生长、疼痛控制和心肌再生相关,靶向AT2R的药物可以改善心血管功能、缓解神经性疼痛等。由澳大利亚Spinifex公司开发的化合物olodanrigan(EMA401)是一种高选择性AT2R拮抗剂,目前处于临床二期,该候选药物对糖尿病性神经痛、带状疱疹后遗神经痛等神经性疼痛具有良好的治疗效果,同时Spinifex公司也在开发AT2R拮抗剂EMA-400。Olodanrigan和EMA-400均通过WO 93/23378制备而得,结构如下:
目前已经公开了一系列的AT2R拮抗剂专利申请,其中包括WO2016113668、WO2015003223和WO2013110135等,AT2R拮抗剂的研究和应用已取得一定的进展,但是提高的空间仍然巨大,仍有必要继续研究和开发新的AT2R拮抗剂。

以SD大鼠为受试动物,采用LC/MS/MS法测定大鼠静脉注射或灌胃给予本发明化合物,测定其不同时刻血浆中的药物浓度,研究本发明化合物在大鼠体内的药代动力学特征。
2、实验方案
2.1、实验药品与动物
化合物1m及化合物1
健康成年Sprague Dawley(SD)雄性大鼠6只,购自维通利华实验动物技术有限公司。
2.2药物配制与给药
(1)药物配置:
称取76.32mg化合物1m,溶于12.72mL 0.5%羧甲基纤维素钠(CMC-Na)中,涡旋1分钟至化合物完全悬浮,最终配置浓度为6mg/mL;
称取76.61mg化合物1,溶于12.768mL 0.5%羧甲基纤维素钠(CMC-Na)中,涡旋1分钟至化合物完全悬浮,最终配置浓度为6mg/mL。
(2)给药
健康成年SD大鼠6只,雌雄各半,平均分成2组;每组3只。禁食过夜后灌胃给药(po)给予本发明化合物1m及化合物1,给药剂量均为60mg/kg。
2.3样品采集
于给药前和给药后0.25小时、0.5小时、1小时、2小时、4小时、6小时、8小时和24小时经颈静脉采约0.25mL血液,肝素钠抗凝。血液样本采集后置于冰上,离心分离血浆(离心条件:7000转/分钟,5分钟)。收集的血浆分析前存放于-70℃以下。
2.4样品前处理
取100μL血浆样品中加入300μL甲醇(包含内标工作液,氯雷他定800ng/mL),涡旋5分钟,10000转/分钟离心10分钟,取1μL混合液至LC-MS/MS进样分析。
3、药代动力学参数结果
本发明的化合物和阳性对照的药代动力学参数如下表所示。
结论:本发明化合物的钠盐(化合物1)与其游离酸相比(化合物1m)相比,血药浓度和曲线下面积均有明显改善。
