Definitions
- the present invention belongs to the field of medicine, and specifically relates to a compound represented by formula I, stereoisomers, tautomers or mixtures thereof, and pharmaceutically acceptable salts, co-crystals, and polymorphs of the compounds Or solvates, or stable isotope derivatives, metabolites or prodrugs of said compounds.
- the compounds of the present invention can be used as PRMT5 modulators (such as inhibitors) for the treatment of diseases (such as tumor diseases) related to PRMT5 activity.
- PRMT5 Protein Arginine Methyltransferase 5
- PRMT5 is an epigenetic enzyme and one of the members of the PRMT family (the human body has PRMT1-11). It can catalyze the methylation modification of arginine residues of histones and certain non-histone substrates.
- PRMT5 is widely present in the nucleus and cytoplasm of human cells, including tissues such as heart, muscle and testis. According to the different ways of catalyzing arginine methylation, it is divided into types I, II, and III.
- PRMT5 belongs to type II symmetric dimethylation (sDMA) PRMT, and its methyl donor is S-adenosylmethionine (SAM).
- sDMA symmetric dimethylation
- SAM S-adenosylmethionine
- PRMT5 catalyzes the arginine methylation of the substrate, regulates the expression of a variety of target proteins, participates in a variety of physiological functions, and plays an important role in tumor cell proliferation, metastasis, and malignant transformation.
- the methylation modification of histones by PRMT5 leads to the silence of tumor suppressor genes such as p53, ST7, NM23 and Rb, which in turn promotes the occurrence and development of tumors.
- PRMT5's regulation of non-histone proteins is mainly reflected in the influence of transcription factors (NF- ⁇ B/P65, E2F1, HoxA ⁇ GATA4), programmed cell death protein 4 (PDCD4), cell cycle and survival-related regulatory proteins E2F1, hypoxia-inducible factors 1 (HIF-1), the location and expression of cyclin-dependent kinases (CDKs), PI3K/Akt, etc. (Koh CM, Bezzi M, Guccione E. Curr Mol Bio Rep, 2015, 1(1): 19-28) .
- PRMT5 can inhibit miR-99 family transcription, increase FGFR3 expression, activate Erk1/2 and Ak pathways, and cause tumor cell growth and metastasis (Pengyu Jing, Nan Zhao, et al. Cancer Letters, 2018, 427, 38- 48).
- PRMT5 in colon cancer can methylate Eif4e and FGFR3, and promote tumor cell growth (ZHANG B, DONG S, ZHU R, et al. Oncotarget, 2015, 6(26): 22799-22811.).
- PRMT5 target regulating tumor proliferation and metastasis is relatively clear, and it is a promising target for tumor therapy.
- PRMT5 target inhibitor on the market. Therefore, it is necessary to develop new, high-efficiency and low-toxicity PRMT5 inhibitors to meet clinical needs.
- the purpose of the present invention is to provide a compound represented by formula I, a preparation method thereof, and its use in preventing/or treating diseases related to PRMT5 activity, such as tumor diseases.

Abstract
本发明涉及氮杂环化合物、其制备方法及用途,具体涉及式I所示的化合物,所述化合物的立体异构体、互变异构体或其混合物,所述化合物的药学上可接受的盐、共晶、多晶型物或溶剂合物,或者所述化合物的稳定同位素衍生物、代谢物或前药,其制备方法和用于治疗肿瘤相关疾病的用途。
Description
本发明属于医药领域,具体涉及式I所示的化合物,所述化合物的立体异构体、互变异构体或其混合物,所述化合物的药学上可接受的盐、共晶、多晶型物或溶剂合物,或者所述化合物的稳定同位素衍生物、代谢物或前药。本发明的化合物可用作PRMT5调节剂(例如抑制剂),用于与PRMT5活性相关的疾病(例如肿瘤疾病)的治疗。
PRMT5(Protein Arginine Methyltransferase 5)属于表观遗传酶,是PRMT家族(人体具有PRMT1-11)成员之一,可催化组蛋白和某些非组蛋白底物的精氨酸残基甲基化修饰。PRMT5广泛存在于人体细胞的细胞核和细胞质中,包括心脏、肌肉和睾丸等组织。根据催化精氨酸甲基化方式的不同分为I、II、III型,PRMT5属于II型对称双甲基化(sDMA)PRMT,其甲基供体为S-腺苷蛋氨酸(SAM)。
PRMT5通过催化底物的精氨酸甲基化,调控多种靶蛋白的表达程度,参与多种生理功能,对肿瘤细胞增殖、转移、恶性转化具有重要作用。PRMT5对组蛋白的甲基化修饰导致p53、ST7、NM23及Rb等抑癌基因的沉默,进而促进肿瘤的发生发展。PRMT5对非组蛋白的调节主要体现在影响转录因子(NF-κB/P65、E2F1、HoxA\GATA4)、程序性细胞死亡蛋白4(PDCD4)、细胞周期及存活相关调节蛋白E2F1、缺氧诱导因子1(HIF-1)、周期蛋白依赖性激酶(CDKs)、PI3K/Akt等的定位及表达(Koh CM,Bezzi M,Guccione E.Curr Mol Bio Rep,2015,1(1):19-28)。肺癌细胞中,PRMT5可抑制miR-99家族转录,增加FGFR3表达,活化Erk1/2和Ak通路,导致肿瘤细胞生长和转移(Pengyu Jing,Nan Zhao,et al.Cancer Letters,2018,427,38-48)。结肠癌中PRMT5可甲基化Eif4e和FGFR3,促进 肿瘤细胞生长(ZHANG B,DONG S,ZHU R,et al.Oncotarget,2015,6(26):22799-22811.)。
综上所述,PRMT5靶点调控肿瘤增殖、转移的机理较为明确,是一个有前景的肿瘤治疗靶点。目前尚未有PRMT5靶点的抑制剂上市。因此,需要开发新的、高效低毒的PRMT5抑制剂来满足临床需求。

本发明在其范围内进一步包括本发明的化合物的前药,其为自身可具有较小药理学活性或无药理学活性的本发明的化合物的某些衍生物,当被给药至身体中或其上时可通过例如水解裂解转化成具有期望活性的本发明的化合物。通常这样的前药会是所述化合物的官能团衍生物,其易于在体内转化成期望的治疗活性化合物。关于前药的使用的其他信息可参见“Pro-drugs as Novel Delivery Systems”,第14卷,ACS Symposium Series(T.Higuchi及V.Stella)及“Bioreversible Carriers in Drug Design,”Pergamon Press,1987(E.B.Roche编辑,American Pharmaceutical Association)。本发明的前药可例如通过用本领域技术人员已知作为“前-部分(pro-moiety)(例如“Design of Prodrugs”,H.Bundgaard(Elsevier,1985)中所述)”的某些部分替代本发明的化合物中存在的适当官能团来制备。
本发明还涵盖含有保护基的本发明的化合物。在制备本发明的化合物的任何过程中,保护在任何有关分子上的敏感基团或反应基团可能是必需的和/或期望的,由此形成本发明的化合物的化学保护的形式。这可以通过常规的保护基实现,例如,在Protective Groups in Organic Chemistry,ed.J.F.W.McOmie,Plenum Press,1973;和T.W.Greene&P.G.M.Wuts,Protective Groups in Organic Synthesis,John Wiley&Sons,1991中所述的那些保护基,这些参考文献通过援引加入本文。使用本领域已知的方法,在适当的后续阶段可以移除保护基。
