Definitions
- the invention relates to a crystal form of a pyridopyrimidine compound and a preparation method thereof, and also includes the application of the crystal form in the preparation of a drug for treating cancer.
- RAS protein is the product expressed by the RAS gene, which refers to a class of closely related monomeric globulins composed of 189 amino acids with a molecular weight of 21KDa. It can bind to guanine trinucleotide phosphate (GTP) or guanine dinucleotide phosphate (GDP).
- GTP guanine trinucleotide phosphate
- GDP guanine dinucleotide phosphate
- the active state of RAS protein has effects on cell growth, differentiation, cytoskeleton, protein transport and secretion, and its activity is regulated by binding to GTP or GDP.
- the RAS protein When the RAS protein binds to GDP, it is in a dormant state, that is, in an "inactive" state; when stimulated by upstream specific cell growth factors, the RAS protein is induced to exchange GDP and bind to GTP, which is called “activation”. condition.
- the RAS protein bound to GTP can activate downstream proteins for signal transmission.
- the RAS protein itself has weak hydrolysis GTP hydrolysis activity and can hydrolyze GTP to GDP. In this way, the transition from the activated state to the deactivated state can be achieved. In this hydrolysis process, GAP (GTPase activating proteins, GTP hydrolase activating proteins) is also required. It can interact with RAS protein, greatly promoting its ability to hydrolyze GTP to GDP.
- RAS protein Mutation of the RAS protein will affect its interaction with GAP, which also affects its ability to hydrolyze GTP to GDP, making it always active. Activated RAS proteins continue to give downstream proteins growth signals, which eventually lead to the continuous growth and differentiation of cells, and ultimately produce tumors.
- GAP Kirsten rat sarcoma virus oncogene homolog
- HRAS Harvey rat sarcoma virus oncogene homolog
- NRAS neuronal Blastoma rat sarcoma virus oncogene homolog
- the G12C mutation is one of the more common mutations in the KRAS gene, which refers to the mutation of glycine No. 12 to cysteine.

Description

PCT/CN2020/112863,申请日2020年09月01日。
本发明涉及一种吡啶并嘧啶化合物的晶型及其制备方法,还包括所述晶型在制备治疗癌症药物中的应用。
第一个RAS癌基因发现自大鼠肉瘤(rat sarcoma),因此得名。RAS蛋白是由RAS基因表达的产物,指一类紧密相关的,由189个氨基酸组成的单体球蛋白,其分子量为21KDa。它可以与鸟嘌呤三核苷酸磷酸(GTP)或鸟嘌呤二核苷酸磷酸(GDP)结合。RAS蛋白的活性状态对细胞的生长、分化、细胞骨架、蛋白质运输和分泌等都具有影响,其活性是通过与GTP或GDP的结合进行调节。当RAS蛋白与GDP结合时,它处于休眠状态,也就是“失活”状态;当有上游特定的细胞生长因子刺激时,RAS蛋白被诱导交换GDP,与GTP结合,此时称为“活化”状态。与GTP结合的RAS蛋白能够活化下游的蛋白,进行信号传递。RAS蛋白自身具有弱的水解GTP水解活性,能够水解GTP到GDP。这样就可以实现从活化状态到失活状态的转化。在这个水解过程中,还需要GAP(GTPase activating proteins,GTP水解酶活化蛋白)参与。它能与RAS蛋白作用,大大促进其水解GTP到GDP的能力。RAS蛋白的突变将影响其与GAP的作用,也就影响了其水解GTP到GDP的能力,使其一直处于活化状态。活化的RAS蛋白持续的给予下游蛋白生长信号,最终导致细胞不停的生长和分化,最终产生肿瘤。RAS基因家族成员众多,其中与各种癌症密切相关的亚家族主要有克尔斯滕大鼠肉瘤病毒致癌基因同源物(KRAS)、哈维大鼠肉瘤病毒致癌同源物(HRAS)和神经母细胞瘤大鼠肉瘤病毒致癌基因同源物(NRAS)。人们发现大约30%的人类肿瘤中都携带某些突变的RAS基因,其中以KRAS突变最为显著,占到所有RAS突变中的86%。对于KRAS突变,最为常见的突变出现在12号甘氨酸(G12),13号甘氨酸(G13)和61号谷氨酰胺(Q61)残基上,其中G12突变占到83%。
G12C突变是KRAS基因突变中比较常见的一个,它是指12号甘氨酸突变为半胱氨酸。KRAS G12C突变在肺癌中最为常见,根据文献(Nat Rev Drug Discov 2014;13:828-851)报道的数据推算,KRAS G12C突变占到所有肺癌患者的10%左右。
KRAS G12C突变蛋白作为一个前沿靶点,目前的研究还不是很多。文献(Nature.2013;503:548-551)报道了一类靶向KRAS G12C突变的共价结合抑制剂,但是这类化合物酶活性不高,在细胞水平也没有表现出显著活性。文献(Science 2016;351:604-608,Cancer Discov 2016;6:316-29)报道了一类化合物在细胞水平表现出了μM级别的细胞抗增殖活性,但是其结构代谢稳定性差,活性也很难进行进一步提高。除了少数的文献报道外,Araxes Pharma LLC公司申请了数篇针对KRAS G12C抑制剂的专利,例如WO2016164675和WO2016168540就报道了一类喹唑啉衍生物具有较高的酶结合活性,且表现出μM级别的细胞抗增殖活性,其结构稳定,并有一定的选择性。这类化合物都具有一个丙烯酰胺的片段,它作为迈克尔加成受体和KRAS蛋白上G12C残基作用形成共价结合复合物。2018年,LiuYi等人在Cell(Matthew R.Janes,Yi Liu et al.,Cell,2018,172,578–589.)上公开报道了靶向KRAS G12C突变的共 价结合抑制剂ARS-1620,该化合物具有很好的代谢稳定性,在细胞水平表现出了nM级别的细胞抗增殖活性,且在胰腺癌MIA-Paca2细胞皮下异种移植肿瘤模型上能有效的抑制肿瘤生长。2018年下半年,Amgen公司的KRAS G12C抑制剂AMG 510开始一期临床招募(NCT03600883),这是首个进入临床研究的有机小分子KRAS G12C抑制剂,在2019年的AACR会议上,AMG 510的结构式及部分临床前的研究数据被公开,2019年的ASCO会议上,公布了AMG 510早期的一期临床结果,AMG 510对接受化疗后疾病进展的具有KRAS G12C突变的非小细胞肺癌患者的疾病控制率达到90%。此外Mirati Therapeutics研发的KRAS G12C抑制剂MRTX849也在2019年1月份开始一期临床招募(NCT03785249),其代表性专利有WO2017201161和WO2019099524。
