Definitions
- the present invention belongs to the field of pharmaceutical chemistry, and in particular relates to a biheterocyclic WRN inhibitor, a preparation method thereof and an application thereof.
- WRN is a member of the RecQ family of DNA helicases and is involved in DNA damage repair, genome stability maintenance, telomere maintenance, etc. WRN gene defects can lead to Werner syndrome (progeria syndrome), a recessive genetic disease characterized by staged premature aging and increased cancer susceptibility (Nat Rev Cancer 2003, 3, 169-178). In 2019, Cancer Dependency Map (DepMap), a project aimed at finding new tumor treatment targets through gene screening, drug sensitivity and drug prediction models, found that WRN is essential for the survival of microsatellite unstable (MSI) tumors.
- MSI microsatellite unstable
- WRN can unwind this structure to restore normal DNA replication.
- the cross-shaped structure will be cut by the nuclease MUS81, resulting in chromosome genome damage and cell death.
- the TA repeat sequence does not form a cross-shaped structure, so WRN deficiency will specifically cause MSI cell death (Nature 2020, 586, 292-298). Therefore, inhibitors targeting the WRN unwinding domain may be an effective measure to treat MSI cancers.
- WRN inhibitors Although some patent applications for WRN inhibitors have been published, new compounds still need to be further developed, as there are currently no WRN target drugs on the market and WRN target inhibition has potential medical value in the treatment of microsatellite instability (MSI) tumors.
- MSI microsatellite instability
- the inventors of the present application designed a compound having a structure shown in general formula (I), and found that compounds having such a structure exhibit excellent WRN inhibition effects and functions, and can be used to treat MSI tumor-related diseases.

Abstract
本发明涉及一种式(I)所示的双杂环WRN抑制剂、其制备方法及其应用。本发明还涉及包含所述化合物作为活性成分的药物组合物以及所述化合物或药物组合物用于治疗和/或预防与WRN生物学活性相关的疾病的用途。
Description
本发明属于药物化学领域,具体涉及一种双杂环WRN抑制剂、其制备方法及其应用。
WRN是DNA解旋酶RecQ家族成员之一,参与DNA损伤修复、基因组稳定性维持、端粒维持等,WRN基因缺陷可导致Werner综合征(早老综合征),一种以阶段性早衰和癌症易感性升高为特征的隐性遗传性疾病(Nat Rev Cancer 2003,3,169-178)。2019年,一项旨在通过基因筛选、药物敏感性和药物预测模型寻找新的肿瘤治疗靶点的项目Cancer Dependency Map(DepMap)发现WRN对于微卫星不稳定(MSI)肿瘤的生存是必需的。研究结果显示,WRN的缺失会引起MSI细胞DNA双链断裂(DSBs)、细胞周期阻滞进而引起细胞凋亡,而对于微卫星稳定(MSS)细胞则无影响(Nature 2019,568,511-516)。进一步的机制研究结果显示,WRN外切酶域功能的完好与否对MSI细胞的生存无明显影响,WRN解旋域功能的完整才是MSI细胞生存所必需的(Life Sci Alliance 4)。此外,MSI细胞中存在大规模扩张且高度不稳定的TA-二核苷酸重复序列,扩张的TA重复序列会形成非B形的十字形DNA二级结构,阻碍复制叉的延伸,WRN可解旋该结构恢复DNA的正常复制,而当WRN缺失时,十字形结构会被核酸酶MUS81切割,导致染色体基因组破坏,进而引起细胞死亡,而在MSS细胞中,TA重复序列则不会形成十字形结构,所以WRN缺失会特异性地导致MSI细胞死亡(Nature 2020,586,292-298)。因此,靶向WRN解旋域的抑制剂可能是治疗MSI癌症的有效措施。
目前暂未发现WRN靶点抑制相关的药物上市,基于WRN靶点抑制在微卫星不稳定(MSI)肿瘤治疗中潜在的医学价值,开发WRN靶点抑制相关的化合物具有十分重要的社会意义和医学价值。
