Definitions

  • the present invention requires the following:
  • the invention belongs to the field of medicine. Specifically, the invention relates to a KIF18A inhibitor and its use.
  • KIF18A is a mitotic kinesin that regulates chromosome positioning during cell division and is overexpressed in some human cancers.
  • TP53-mutant unstable aneuploid cancer cells characterized by chromosomal instability (CIN) rely on KIF18A motor activity to prevent lethal multipolar cell division.
  • the KIF18A gene belongs to the kinesin-8 subfamily and is a plus-end directed motor.
  • KIF18A is thought to influence the dynamics of the plus ends of centromeric microtubules to control correct chromosome positioning and spindle tension. Depletion of human KIF18A results in longer spindles, increased chromosome oscillations during metaphase, and activation of the mitotic spindle assembly checkpoint in HeLa cervical cancer cells.
  • KIF18A is overexpressed in multiple types of cancer, including but not limited to colon, breast, lung, pancreatic, prostate, bladder, head, neck, cervix, and ovarian cancers. Furthermore, in cancer cell lines, gene deletion or knockout or KIF18A inhibition affects the mitotic spindle apparatus. In particular, inhibition of KIF18A has been found to induce mitotic cell arrest, which can promote mitotic cell death through apoptosis, mitotic catastrophe, or polyphasic driven lethality or death following mitotic slippage during interphase.

技术领域
本发明属于医药领域,具体地,本发明涉及到一种KIF18A抑制剂及用途。
背景技术
KIF18A是一种有丝分裂驱动蛋白,在细胞分裂过程中调节染色体定位,在一部分人类癌症中过表达。具有染色体不稳定性(CIN)特征的TP53突变不稳定非整倍体癌细胞依赖KIF18A运动活性来阻止致死性多极细胞分裂。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以及有丝分裂纺锤体组装检查点的激活。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,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。
目前尚无KIF18A抑制途径治疗包括癌症在内的众多病症的药物上市。因此,开发新的可抑制KIF18A活性的化合物对于疾病的治疗具有积极意义。
