Definitions

  • the present invention relates to the field of medicinal chemistry, and more particularly, to a class of spiro derivatives as KIF18A inhibitors.
  • Cancer is one of the most common diseases that afflicts humans, and is one of the leading causes of death worldwide. Cancer is often characterized by unregulated cell proliferation. Damage to one or more genes responsible for cellular pathways (the progression of proliferation controlled by cell cycle and centrosome circulation) can cause the normal regulation of cell proliferation to be lost. These unregulated genes can encode various tumor suppressors or oncogene proteins, which participate in a series of events, leading to unchecked cell cycle progression and cell proliferation. Various kinases and kinesins have been identified to play a key role in the cell cycle and mitosis regulation and progression of normal dividing cells and cancer cells.
  • the KIF18A gene belongs to the kinesin-8 subfamily and is a plus-end directed motor. KIF18A is thought to affect the dynamics of the plus ends of centromeric microtubules to control correct chromosome positioning and spindle tension. Depletion of human KIF18A leads to longer spindles, increased chromosome oscillation in metaphase, and activation of the mitotic spindle assembly checkpoint in HeLa cervical cancer cells (MI Mayr et al., Current Biology 17, 488-98, 2007). KIF18A appears to be a viable target for cancer therapy.
  • KIF18A is overexpressed in multiple types of cancer, including but not limited to colon cancer, breast cancer, lung cancer, pancreatic cancer, prostate cancer, bladder cancer, head cancer, neck cancer, cervical cancer, and ovarian cancer.
  • gene deletion or knockout or KIF18A inhibition affects the mitotic spindle apparatus.
  • inhibition of KIF18A has been found to induce mitotic cell arrest, a known weakness that can promote mitotic cell death by apoptosis, mitotic catastrophe, or multiphasic driven lethality or death following mitotic slippage in interphase.
  • the technical problem to be solved by the present invention is that there are few types of existing KIF18A inhibitors.
  • the present invention provides spiro derivatives as KIF18A inhibitors.
  • the spiro derivatives are a class of compounds with novel structures and good KIF18A inhibitory activity.

Description

一类螺环衍生物作为KIF18A抑制剂
本申请要求于2022年11月25日提交的申请号为202211486927.1、发明名称为“一类螺环衍生物作为KIF18A抑制剂”的中国专利申请的优先权,在此通过引用将其全文并入本文。
技术领域
本发明涉及药物化学领域,更具体地,本发明涉及一类螺环衍生物作为KIF18A抑制剂。
背景技术
癌症是折磨人类最普遍的疾病之一,并且是世界范围内的主要死亡原因之一。癌症的特征通常在于不受调节的细胞增殖。对细胞途径负责的一个或更多个基因(通过细胞周期和中心体循环控制增殖的进展)的损坏可以引起细胞增殖的正常调节丧失。这些失调的基因可以编码各种肿瘤抑制物或癌基因蛋白,它们参与一系列事件,导致未经检查的细胞周期进展和细胞增殖。各种激酶和驱动蛋白已经被鉴定在正常分裂的细胞和癌细胞的细胞周期和有丝分裂调节和进展中起关键作用。
KIF18A基因属于驱动蛋白-8亚家族并且是一个正端定向马达。KIF18A被认为影响着丝粒微管的正端的动力学以控制正确的染色体定位和纺锤体张力。人KIF18A的耗尽在HeLa宫颈癌细胞中导致更长的纺锤体,在中期增加的染色体振荡(chromosome oscillation)以及有丝分裂纺锤体组装检查点的激活(MI Mayr等人,Current Biology[当代生物学]17,488-98,2007)。KIF18A似乎是癌症治疗的可行靶标。KIF18A在多种类型的癌症中过表达,包括但不限于结肠癌、乳腺癌、肺癌、胰腺癌、前列腺癌、膀胱癌、头癌、颈癌、子宫颈癌和卵巢癌。此外,在癌细胞系中,基因缺失或敲除或者KIF18A抑制影响有丝分裂纺锤体装置。特别地,已发现抑制KIF18A来诱导有丝分裂细胞停滞,这是一种已知的弱点,其可以通过凋亡、有丝分裂灾变或多相驱动致死性或分裂间期中有丝分裂滑脱后的死亡来促进有丝分裂细胞死亡。
因此,急需开发一种新的KIF18A蛋白的抑制剂。
