Definitions

  • the present invention requires the following:
  • the invention belongs to the field of medicine, and specifically relates to a KIF18A inhibitor compound, a pharmaceutical composition and a preparation method and application thereof.
  • Cancer is one of the most serious diseases affecting human health, with mortality and morbidity often ranking among the top among various diseases. Although the quality of life of some patients has been greatly improved with the continuous development and progress of medical technology and drug research and development, there are still more unidentified drugs on the road to finding effective treatments or cures for different cancers. meet clinical needs, and more new targets will provide new possibilities for future cancer drug development.
  • Unregulated cell proliferation in cancer cells occurs due to damage or deletion of one or more genes that regulate the cell cycle.
  • Various kinases and kinesins have been identified to play critical roles in cell cycle and mitotic regulation and progression in normally dividing cells and cancer cells.
  • Kinesin molecules are dynein molecules that use intracellular microtubules as tracks. They are also called molecular motors. They can convert ATP energy into mechanical energy. They are used in eukaryotic cells and cell mitosis and meiosis, the growth and development of tissues and organs, and the growth of neurons. Development and signal transduction are closely related. Kinesin members share a relatively conserved motor domain.
  • N-type kinesin that is, the amino (-NH 2 ) terminal region of the protein polypeptide chain has a motor domain
  • M-type kinesin that is, the middle region Has a motor domain
  • C-type kinesin that is, the carboxyl (-COOH) terminal region has a motor domain.
  • Chromosomal instability is a hallmark of cancer and results from errors in chromosome segregation during mitosis.
  • Targeting chromosomal instability is an emerging therapeutic strategy in drug development.
  • KIF18A a member of the N-type Kinesin-8 kinesin family, has been shown to play a role in maintaining bipolar spindle integrity and promoting the viability of cancer cells with chromosomal instability.
  • Mitosis is an effective point of intervention, and many antimitotic drugs are used clinically to treat human cancers. The most widely used tubulin inhibitor, it can both stabilize microtubules and prevent microtubule assembly. Current anti-mitotic drugs have limitations such as narrow therapeutic windows, and these problems require the development of new targets to solve.
  • tubulin inhibitors are widely used as standard treatments for many human cancer types, these drugs are associated with collateral damage to normal cells, including myelosuppression and neurotoxicity. Since KIF18A may not be essential in normal diploid somatic cells (KIF18A knockout mice are viable but defective in reproduction, suggesting that KIF18A is not an essential gene for normal somatic cell division), targeting KIF18A It is possible to significantly reduce its toxicity and help improve the therapeutic safety window of tubulin-targeted drugs in clinical practice.
  • KIF18A protein is highly expressed in a variety of tumors, including colon cancer, breast cancer, lung cancer, pancreatic cancer, prostate cancer, bladder cancer, head and neck cancer, cervical cancer and ovarian cancer.
  • KIF18A plays a key role in the occurrence, development and metastasis of breast cancer, and its high expression predicts poor prognosis of patients.
  • KIF18A is required for proliferation of cells with chromosomal instability derived from triple-negative breast cancer or colorectal cancer, but is not required in diploid cells. Knocking out the KIF18A gene resulted in infertility in male mice, but not in female mice.
  • KIF18A mRNA expression was significantly associated with higher tumor grade and larger tumors in breast cancer patients, and KIF18A was an independent predictor of breast cancer lymph node metastasis, with a risk coefficient of 3.2.
  • inhibiting the expression of KIF18A not only affects the key function of KIF18A in cell mitosis, but also reduces cancer cell migration by stabilizing leading microtubules, ultimately leading to the inactivation of the PI3K-AKT signaling pathway and inducing cell apoptosis.
  • KIF18A protein inhibitors may be a new breakthrough in cancer drugs.

技术领域
本发明属于医药领域,具体涉及一种KIF18A抑制剂化合物、药物组合物及其制备方法和应用。
背景技术
癌症是影响人类健康的最严重的疾病之一,死亡率和发病率常居各种疾病前列。虽然随着医疗技术和药物研发的不断发展和进步,部分患者的生活质量得到了极大的改善,但是在寻求针对不同癌症的有效治疗或治愈的药物的路途中,还有更多的未被满足的临床需求,而更多的新靶点将为未来癌症药物研发提供新的可能。
由于调控细胞周期的一个或多个基因的损伤或缺失,导致癌细胞出现不受调节的细胞增殖。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。
驱动蛋白分子是以细胞内微管为轨道的动力蛋白,也称为分子马达,可以将ATP能转变为机械能,在真核细胞与细胞有丝分裂及减数分裂、组织器官的生长发育以及神经元的发育及信号传导等密切相关。驱动蛋白成员共享一个相对保守的马达结构域。根据分子中马达结构域的位置,驱动蛋白家族大致分为三类:N型驱动蛋白,即蛋白质多肽链的氨基(-NH2)末端区域具有一个马达结构域;M型驱动蛋白,即中间区域具有一个马达结构域;C型驱动蛋白,即羧基(-COOH)末端区域具有一个马达结构域。
染色体不稳定性是癌症的一个标志,由有丝分裂期间的染色体分离错误导致。靶向染色体不稳定性是药物开发中一种新兴的治疗策略。KIF18A是N型Kinesin-8驱动蛋白家族中的一员,已被证明在维持双极纺锤体的完整性和促进染色体不稳定性癌细胞的生存能力方面发挥作用。有丝分裂是一个有效的干预点,许多抗有丝分裂药物被用于临床治疗人类癌症。应用最广泛的微管蛋白抑制剂,它既可以稳定微管,也可以防止微管组装。目前抗有丝分裂的药物存在治疗窗较窄的局限性,这些问题需要开发新的靶点来解决。
尽管微管蛋白抑制剂被广泛用作治疗多种人类癌症类型的标准治疗方法,但这些药物存在对正常细胞的附带损伤,包括骨髓抑制和神经毒性。由于KIF18A在正常二倍体体细胞中可能不是必须的(KIF18A基因敲除小鼠是可存活的,但在生殖方面存在缺陷,这表明KIF18A不是正常体细胞分裂的必要基因),因此靶向KIF18A有可能会显著降低其毒性,有利于提升临床中靶向微管蛋白药物的治疗安全窗。
KIF18A蛋白在多种肿瘤中均有高表达,包括结肠癌、乳腺癌、肺癌、胰腺癌、前列腺癌、膀胱癌、头颈部癌、宫颈癌和卵巢癌。KIF18A在乳腺癌发生、发展和转移过程中起关键作用,其高表达预示患者不良预后。KIF18A是来源于三阴性乳腺癌或结直肠癌的染色体不稳定性细胞增殖所必需的,但在二倍体细胞中不需要KIF18A。敲除KIF18A基因可导致雄性小鼠不育,但雌性小鼠没有受到影响。KIF18A mRNA表达与乳腺癌患者中较高的肿瘤等级和较大的肿瘤显著相关,且KIF18A是乳腺癌淋巴结转移的独立预测因素,风险系数为3.2。此外,抑制KIF18A表达不仅影响KIF18A在细胞有丝分裂中的关键功能,还能够通过稳定前沿微管来减少癌细胞迁移,最终导致PI3K-AKT信号通路失活而诱导细胞凋亡。
因此,对KIF18A蛋白抑制剂的开发可能是癌症药物的一个新的突破。
