Definitions

  • the invention relates to an arylamino derivative estrogen receptor modulator and its use in the preparation of medicines for treating/preventing ER-related diseases.
  • Estrogen includes estrone, estradiol, etc., which are mainly secreted by the ovary, and a small amount is secreted by the liver, adrenal cortex and breast.
  • Estrogen Receptor As the main sex hormone of female animals, estrogen promotes the maturation of female accessory sex organs and the emergence of secondary sexual characteristics, and maintains normal sexual desire and reproductive function. Its role is mainly to diffuse into the nucleus and form a complex with estrogen receptor (Estrogen Receptor, ER).
  • Estrogen Receptor ER
  • Enhancers include Estrogen Response Elements (ERE) and other binding elements, and recruit other transcription factors to form a transcription initiation complex to induce transcription.
  • activated estrogen receptors can also recruit transcriptional co-factors and bind to activating protein 1 (Activating Protein 1, AP-1) located in the promoter region of target genes, thereby regulating gene transcriptional activity.
  • the estrogen receptor (ER) is a transcriptional regulatory protein that mediates ligand activation induced by a variety of biological effects through its interaction with endogenous estrogens.
  • ER consists of two subtypes: ER ⁇ and ER ⁇ , each encoded by a different gene.
  • ER ⁇ and ER ⁇ show a high degree of similarity at the amino acid level, with 97% similarity in the DNA-binding domain and 56% similarity in the ligand-binding domain. However, there is only 24% similarity in the N-terminus. low homology.
  • ER contains 6 structural domains (AF), which consist of 4 main functional regions.
  • the functional region of the N-terminal A/B domain has a ligand-independent transcriptional activation functional region AF-1, and AF-1 has constitutive activation activity. Activate the transcription of target genes by interacting with basic transcription factors, resurrection factors and other transcription factors. There are multiple phosphorylation sites in this region. It has been reported in the literature that the effect of AF-1 depends on protein phosphorylation.
  • the DNA-binding domain (DBD) composed of the C domain is highly conserved and contains two zinc finger domains, which can specifically bind to the target DNA, and this domain plays an important role in the dimerization of the receptor .
  • the D domain is the hinge region, linking the DBD and the ligand domain (LBD), with low conservation (the homology between the two subtypes is only 30%).
  • the C-terminal E domain constitutes the ligand-binding domain (LBD), which determines the interaction between ER and ligands such as estrogen, SERM (selective estrogen receptor modulator), SERD (selective estrogen receptor down-regulator), etc. specific binding.
  • LBD has a ligand-dependent transcriptional activation functional domain AF-2, which cooperates with AF-1 to play the function of ER receptors to activate the transcription of target genes.
  • AF-2 ligand-dependent transcriptional activation functional domain
  • LBD has a strong dimerization interface and can still function without ligand. Therefore, LBD is the key site for receptor dimerization.
  • ER ⁇ is mainly distributed in the uterus, ovary, testis, pituitary, kidney, epididymis and adrenal gland, while ER ⁇ is mainly distributed in the prostate, ovary, lung, bladder, brain and blood vessels. Due to the serious side effects of full agonists or full antagonists, the study of selective estrogen receptor modulator SERM came into being. Its "selectivity" means that SERM acts as an agonist in certain tissues such as bone, liver, and cardiovascular system ER ⁇ concentration areas, while it acts as an antagonist in other tissues such as breast. It can be either an agonist or an antagonist in the uterus (where ER alpha is more prominent).
  • SERMs currently on the market include Tamoxifen, Raloxifene, Bazedoxifene, Toremifene, etc., but studies have found that SERMs currently on the market still have severe For example, long-term use of tamoxifen and toremifene can cause endometrial hyperplasia, polyps, and endometrial cancer, while common side effects of raloxifene include hot flashes, leg pain, breast tenderness, and venous Embolism, etc. Therefore, the research and development of new compounds is still an urgent problem to be solved.
  • SESDs Selective Estrogen Receptor Degraders
  • E3 ubiquitin ligases by binding to estrogen receptors and inducing their conformational changes, resulting in the exposure of hydrophobic residues to the molecular surface.
  • Ubiquitin ligases modify estrogen receptor ubiquitination and ultimately direct it to the proteasome for degradation.
  • SERD can also degrade mutated estrogen receptors, thereby avoiding the emergence of drug resistance.
  • Fulvestrant is currently the only SERD drug approved for clinical use in the treatment of ER+ breast cancer, but it has poor druggability, rapid metabolism and must be administered by monthly intramuscular injections, unlike those seen in in vitro studies This limits the effective degradation of ER compared to complete ER degradation (-50% ER degradation in clinical samples).
  • Selective estrogen receptor down-regulators have shown certain therapeutic advantages, but more orally available SERDs still need to be developed, so that candidate drugs have more excellent properties, such as better efficacy, lower side effects, and better pharmacokinetic properties , longer dosing intervals, etc., so as to be better used for the prevention or treatment of estrogen receptor-related diseases. But so far, there are still no effective oral ER degraders on the market, so oral ER degraders with high inhibitory activity and low toxicity still represent an unmet clinical need.
  • the object of the present invention is to provide a selective estrogen receptor down-regulator compound, its stereoisomer, solvate, deuterium or pharmaceutically acceptable salt, and its medical application.
  • the compound has good curative effect, It has the advantages of low toxic and side effects, good safety, high selectivity, good pharmacokinetics, high bioavailability, and no inhibition of CYP enzymes.

Description

芳氨基衍生物雌激素受体调节剂及其用途 技术领域
本发明涉及一种芳氨基衍生物雌激素受体调节剂,其在制备治疗/预防ER相关疾病的药物中的用途。
背景技术
雌激素(Estrogen)包括雌酮(Estrone)、雌二醇(Estradiol)等,主要由卵巢分泌,少量由肝、肾上腺皮质及乳房分泌。作为雌性动物的主要性激素,雌激素促进女性附性器官成熟及第二性征出现,并维持正常性欲及生殖功能。其作用主要是通过扩散进入细胞核,并和雌激素受体(Estrogen Receptor,ER)特异性结合而形成复合物,激活的雌激素受体很快形成同源或异源二聚体,并与DNA增强子(Enhancer)包括雌激素应答元件(Estrogen Response Element,ERE)等结合,并召集其它转录因子形成转录起始复合物从而诱导转录。此外,激活的雌激素受体还能召集转录辅助因子(Transcriptional co-factors),并结合到位于靶基因启动区的活化蛋白1(Activating Protein 1,AP-1),从而调节基因转录活性。
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包含两种亚型:分别由不同基因编码的ER α和ER β。ER α和ER β在氨基酸水平上显现高度的相似性,其在DNA结合结构域的相似度高达97%,配体结合结构域的相似度达56%,然而,在N末端仅有24%的低同源性。ER包含6个结构域(A-F),组成4个主要的功能区,N端A/B域的功能区具有非配体依赖的转录激活功能区AF-1,AF-1具有组成性激活活性,通过与基础转录因子、复活因子和其它转录因子的作用激活靶标基因的转录,该区域有多个磷酸化位点,有文献报导AF-1的作用依赖于蛋白的磷酸化。C域组成的DNA结合结构域(DBD)具有高度的保守性,包含2个锌指结构域,能特异性地结合到靶标DNA上,同时该结构域对受体的二聚化具有重要的作用。D域为铰链区,链接DBD和配体结构域(LBD),保守性较低(两亚型间的同源性仅30%)。C端的E域组成配体结合结构域(LBD),该结构域决定ER与雌激素、SERM(选择性雌激素受体调节剂)、SERD(选择性雌激素受体下调剂)等配体的特异性结合。LBD具有配体依赖的转录激活功能区AF-2,与AF-1协同作用发挥ER受体激活靶基因转录的功能。同时,LBD具有很强的二聚化界面,并在没有配体的情况下仍能发挥作用,因此,LBD是受体发生二聚化的关键部位。
ER α主要分布在子宫、卵巢、睾丸、垂体、肾、附睾和肾上腺中,而ER β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(ER α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。
选择性雌激素受体降解剂(Selective Estrogen Receptor Degraders,SERDs)通过与雌激素受体结合并诱导其构象变化,导致疏水残基暴露于分子表面,从而召集E3泛素连接酶。泛素连接酶通过修饰雌激素受体泛素化,并最终引导其至蛋白酶体而被降解。通过降解雌激素受体,我们可以更加彻底地阻滞雌激素信号传导通路,并避免其召集转录激活因子而成为“激动剂”。此外,SERD还可以降解突变的雌激素受体,从而避免抗药性的出现。
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,快速新陈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~50%ER降解)。
选择性雌激素受体下调剂已显示一定治疗优势,但仍然需要开发更多的可口服的SERD,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、更优的药代特性、给药间隔更长等,从而更好的用于预防或治疗雌激素受体相关疾病。但到目前为止,仍然没有上市有效的口服ER降解剂,因此抑制活性高,毒性低的口服ER降解剂仍代表了一种未被满足的临床需求。

数据处理:数据分析处理采用pClamp 10,GraphPad Prism 5和Excel软件。不同化合物浓度对hERG钾电流(-50mV时诱发的hERG尾电流峰值)的抑制程度用以下公式计算:

其中,Inhibition%代表化合物对hERG钾电流的抑制百分率,I和Io分别表示在加药后和加药前hERG钾电流的幅度。
化合物IC 50使用GraphPad Prism 5软件通过以下方程拟合计算得出:
Y=Bottom+(Top-Bottom)/(1+10^((LogIC50-X)*HillSlope))
其中,X为供试品检测浓度的Log值,Y为对应浓度下抑制百分率,Bottom和Top分别为最小和最大抑制百分率。
