Definitions

  • the present invention relates to a novel KRAS G12C inhibitor compound and the use of the inhibitor compound to prevent or treat KRAS G12C-mediated diseases.
  • KRAS Kirsten rat sarcoma virus gene homolog
  • KRAS mutants encode abnormal proteins that stimulate and promote the growth and spread of malignant tumor cells; Signal influence of upstream EGFR.
  • KRAS mutation promotes cell proliferation, transformation and anti-apoptosis by activating its downstream RAS-RAF-MEK-MAPK and P13K-AKT-mTOR and other cell signal transduction pathways, leading to tumorigenesis and development.
  • KRAS gene point mutations accounts for about 30% of all human tumors, including 90% of pancreatic cancer, 45% of colon cancer, and 35% of non-small cell lung cancer.
  • 80% of KRAS mutations occur in the 12th codon, causing a single amino acid substitution, that is, glycine (G) is replaced by alanine (A), cysteine (C), aspartic acid (D), serine ( S), arginine (R) and valine (V), among which glycine (G) is replaced with cysteine (C) the most common.
  • KRAS G12C mutant protein has a large proportion (14%) in lung cancer, especially non-small cell lung cancer; in addition, it is also expressed in some patients with colorectal cancer (4%) and pancreatic cancer (2%).
  • KRAS G12C Due to the high expression of KRAS G12C mutation in tumor patients, it will also make patients resistant to other targeted drugs, which has attracted the attention of more and more experts and researchers.

  • the “Everest” in the pharmaceutical industry has not been overcome for 30 years.
  • New drug research and development is a rapidly developing field, and technological advancements have accelerated the discovery of candidate drugs.

  • the ideal drug needs to have a long-lasting drug action time and good bioavailability. Every year, a large number of drug candidates are eliminated because of their poor pharmacokinetic parameters and metabolic characteristics. Therefore, the metabolic characteristics and pharmacokinetic parameters of a candidate drug are important evaluation indicators for whether it can be made into a drug, and good pharmacokinetic parameters and metabolic characteristics are necessary for a promising lead compound. Therefore, it is possible to provide KRAS G12C inhibitors with good pharmacokinetic characteristics to exert pharmacodynamic effects in vivo more effectively.

本发明涉及一种新型KRAS G12C抑制剂化合物以及使用该抑制剂化合物预防或治疗KRAS G12C介导的疾病的用途。
背景技术
Kirsten大鼠肉瘤病毒基因同源物(KRAS)突变在1984年NSCLC基因中首次被描述,是一种膜结合型的蛋白,定位于细胞膜内侧;同时位于EGFR信号通路上,对于肿瘤的发生及发展非常重要,正常情况下KRAS蛋白和GDP结合没有活性,当细胞外的生长分化因子把信号传到KRAS蛋白时,增强了其与GTP结合活性,使蛋白和GTP结合成为激活状态,信号系统开放。肿瘤细胞的生长、增殖、血管生成等过程都需要细胞内蛋白进行信号传导,而KRAS基因是传导蛋白的决定因素,KRAS突变型编码异常的蛋白,刺激促进恶性肿瘤细胞生长和扩散;并且不受上游EGFR的信号影响。KRAS突变通过激活其下游RAS-RAF-MEK-MAPK和P13K-AKT-mTOR等多种细胞信号转导通路促进细胞的增殖、转化和抗凋亡,从而导致肿瘤发生和发展。
据COSMIC统计结果显示,KRAS基因点突变发生率在人类所有肿瘤中约占30%,其中胰腺癌90%,结肠癌45%,非小细胞肺癌35%。80%的KRAS突变发生在第12位密码子,引起单个氨基酸替换,即甘氨酸(G)替换为丙氨酸(A)、半胱氨酸(C)、天冬氨酸(D)、丝氨酸(S)、精氨酸(R)和缬氨酸(V),其中以甘氨酸(G)替换为半胱氨酸(C)最为常见。KRAS G12C突变蛋白,在肺癌、尤其是非小细胞肺癌中比例较大(14%);此外还在一些结直肠癌(4%)、胰腺癌(2%)患者体内表达。
由于KRAS G12C突变在肿瘤患者中的较高的表达,还会使患者对其他靶向药物产生耐药性,引起了越来越多的专家及学者的高度重视。但是,直接针对KRAS G12C靶点抑制剂的药物研发受到生物化学复杂性的挑战,堪称肿瘤学“不可成药”靶标的代名词,制药界的“珠峰”,三十年来尚未攻克。
新药研发是一个快速发展的领域,技术的进步加快了候选药物的发现。在这些候选药物中,不仅需要对其药效学进行评价,药物代谢和动力学性质也是非常重要的新药筛选指标。理想的药物需要具有持久的药物作用时间和良好的生物利用度。每年都会有大量的候选药物因为其药代动力学参数和代谢特征不佳而被淘汰。因此,候选药物的代谢特征和药代参数是其是否能够成药的重要评价指标,良好的药动学参数和代谢特征是具有发展前景的先导化合物所必备的。因此,提供具有良好药代动力学特征的KRAS G12C抑制剂将有可能更有效的在体内发挥药效学作用。
