Definitions
- the present invention relates to a new aromatic ring or heteroaromatic ring derivative, a preparation method thereof, a pharmaceutical composition containing the derivative, and its use as a therapeutic agent, especially an angiotensin II type 2 receptor (AT 2 R) The use of antagonists.
- Neuropathic pain is a chronic pain disease caused by primary damage or dysfunction of the nervous system. According to the location of the disease, it can be divided into peripheral neuropathic pain and central neuropathic pain. Trauma, inflammation, infection or compression can cause neuropathic pain, such as diabetic neuralgia (DNP), postherpetic neuralgia (PHN), primary neuropathy, secondary neuropathy, peripheral neuropathy, Neurological diseases caused by mechanical nerve damage or biochemical nerve damage.
- DNP diabetic neuralgia
- PPN postherpetic neuralgia
- primary neuropathy secondary neuropathy
- peripheral neuropathy Neurological diseases caused by mechanical nerve damage or biochemical nerve damage.
- the clinical drugs used to treat neuropathic pain mainly include antiepileptic drugs, antidepressants, and narcotic analgesics, such as gabapentin, pregabalin, tricyclic antidepressants, etc.
- Angiotensin II receptor is a G protein-coupled receptor with angiotensin II as a ligand. It is an important part of the renin-angiotensin system.
- the main subtypes of angiotensin II receptors include type 1 receptor (AT 1 R) and type 2 receptor (AT 2 R). AT 1 R and AT 2 R are only about 30% identical in amino acid sequence, but angiotensin II, as its main ligand, has a similar affinity to the two.
- AT 1 R is the most clearly studied angiotensin receptor.
- AT 1 R receptor activation can cause smooth muscle contraction, aldosterone and vasopressin secretion, increased renal tubular reabsorption sodium, central and peripheral sympathetic nerve activation, and myocardial hypertrophy. Therefore, antagonizing angiotensin II at the receptor level has become a search The research hotspot of new antihypertensive drugs, and a series of sartan antihypertensive drugs were born.
- AT 2 R is abundantly expressed in various embryonic tissues and less distributed in adult normal tissues, but its expression increases after tissue injury.
- AT 2 R is related to blood pressure regulation, nerve growth, pain control and myocardial regeneration. Drugs targeting AT 2 R can improve cardiovascular function and relieve neuropathic pain.
- the compound olodanrigan (EMA401) developed by Spinifex in Australia is a highly selective AT 2 R antagonist and is currently in clinical phase II.
- the candidate drug is effective for neuropathic pain such as diabetic neuralgia and postherpetic neuralgia. Good therapeutic effect, and Spinifex is also developing AT 2 R antagonist EMA-400.

Abstract
本发明涉及芳环或杂芳环类衍生物、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)所示的芳环或杂芳环类衍生物、其制备方法及其可药用的盐,以及它们作为治疗剂,特别是血管紧张素II 2型受体(AT 2R)拮抗剂的用途,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
本申请要求于2019年5月10日提交到中国专利局的发明名称为“芳环或杂芳环类衍生物及其制备方法和用途”的中国专利申请201910386712.4的优先权,其内容通过引用以整体并入本文。
本发明涉及一种新的芳环或杂芳环类衍生物、其制备方法、含有该衍生物的药物组合物以及其作为治疗剂特别是作为血管紧张素II 2型受体(AT
2R)拮抗剂的用途。
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(AT
1R)和2型受体(AT
2R)。AT
1R和AT
2R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。
AT
1R是被研究得最清楚的血管紧张素受体。AT
1R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。
AT
2R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。AT
2R与血压调控、神经生长、疼痛控制和心肌再生相关,靶向AT
2R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AT
2R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AT
2R拮抗剂EMA-400。Olodanrigan和EMA-400均可通过WO 93/23378公开的方法制备而得,结构如下:
目前已经公开了一系列的AT
2R拮抗剂专利申请,其中包括WO2016113668、WO2015003223和WO2013110135等,AT
2R拮抗剂的研究和应用虽已取得一定的进展,但是提高的空间仍然巨大,仍需要具有更好效果的新的AT
2R拮抗剂化合物,仍有必要继续研究和开发新的AT
2R拮抗剂。

“离去基团(leaving group)”,或称离去基,在化学反应中从一较大分子中脱离的原子或官能基,是亲核取代反应与消除反应中应用的术语。在亲核取代反应中,被亲核试剂进攻的反应物称为底物(substrate),而从底物分子中带着一对电子断裂出去的原子或原子团称为离去基团。易接受电子、承受负电荷能力强的基团是好的离去基团。当离去基团共轭酸的pKa越小,离去基团越容易从其他分子中脱离。原因是因为当其共轭酸的pKa越小,相应离去基团不需和其他原子结合,以阴离子(或电中性离去基团)的形式存在的趋势也就增强。常见的离去基团包括但不限于卤素、-OTs或-OH。
