  • ER ⁇ is mainly distributed in the uterus, ovary, testis, pituitary gland, kidney, epididymis and adrenal gland, while ER ⁇ is mainly distributed in the prostate, ovary, lung, bladder, brain and blood vessels. Since full agonists or full antagonists have serious side effects, research on selective estrogen receptor modulators SERMs emerged as the times require.

Description

杂芳基并哌啶类衍生物及其药物组合物和应用 技术领域
本发明属于医药领域,具体涉及一种杂芳基并哌啶类衍生物及其药物组合物和应用。
背景技术
雌激素受体(ER)是一种通过其与内源性雌激素的相互作用介导多种生物效应诱导的配体活化的转录调节蛋白,ER包含ERα和ERβ两种亚型。ERα主要分布在子宫、卵巢、睾丸、垂体、肾、附睾和肾上腺中,而ERβ主要分布在前列腺、卵巢、肺、膀胱、脑和血管中。由于全激动剂或全拮抗剂都有较严重的副作用,选择性雌激素受体调节剂SERM的研究应运而生。其“选择性”是指SERM在某些组织如骨、肝、心血管系统ERβ集中区中表现为激动剂,而在另外一些组织如乳腺中表现为拮抗剂。其在子宫(ERα较显著区)中可以是激动剂,也可以是拮抗剂。目前已上市的SERM包括他莫昔芬(Tamoxifen)、雷洛昔芬(Raloxifene)、苯卓昔芬(Bazedoxifene)、托瑞米芬(Toremifene)等,但研究发现目前已上市的SERM仍有严重的副作用,如他莫昔芬和托瑞米芬长期服用会引起子宫内膜增生、息肉和子宫内膜癌等,而雷洛昔芬常见的副作用包括潮热、腿痛、乳房触痛和静脉栓塞等。因此研究并开发新型的化合物仍是亟需解决的问题。
选择性雌激素受体讲解剂(SERD)是一类能够通过抑制雌激素受体两个转录激活域AF1和AF2的功能而阻断雌激素的活性的药物,是一类经典的抗雌激素类药物(完全拮抗剂)。氟维司群是目前被批准用于临床使用的唯一SERD类药物,用于治疗ER+乳腺癌,但其成药特性差,快速代谢并且必须通过每月肌肉注射来施用,与体外研究中见到的完全ER降解相比,其限制了ER的有效降解(在临床样品中约有50%ER降解)。
临床上对能够抑制雌激素受体活性、下调雌激素受体表达水平或诱导雌激素受体降解的药物需求强烈,以改善针对早期、转移性、或耐药性的乳腺癌或其它 与雌激素受体过度活性相关疾病的治疗效果。
Roche/Genentech公司的WO2016097072A专利公开了一系列SERD类化合物,其中实施例340被选中作为临床试验分子开展后续研究,即GDC-9545。
目前,选择性雌激素受体降解剂已显示一定治疗优势,但仍然需要开发更多的可口服的选择性雌激素受体降解剂,使得候选药物具有更加优异的特性,如疗效更好、副作用更低、口服吸收更好、更优的药代动力学特性、更好的血脑屏障穿透能力以及更高的心脏安全性等,从而更好的用于预防或治疗雌激素受体相关疾病。
