  • the active state of RAS protein has an impact on cell growth, differentiation, cytoskeleton, protein transport and secretion, etc. Its activity is regulated by the combination with GTP or GDP.
  • the RAS protein When the RAS protein binds to GDP, it is in a dormant state, that is, an "inactive" state; when stimulated by a specific upstream cell growth factor, the RAS protein is induced to exchange GDP and bind to GTP, which is called “activated” at this time. state.
  • the RAS protein bound to GTP can activate downstream proteins for signal transmission.
  • RAS protein itself has weak GTP hydrolysis activity and can hydrolyze GTP to GDP. In this way, the transformation from the activated state to the inactivated state can be realized.

  • GAP GTPase activating proteins
  • RAS protein will affect its interaction with GAP, which will also affect its ability to hydrolyze GTP to GDP, making it always in an activated state.
  • the activated RAS protein continuously gives growth signals to downstream proteins, which eventually leads to the continuous growth and differentiation of cells, and eventually tumors.
  • RAS gene family There are many members of the RAS gene family, among which the subfamilies closely related to various cancers are mainly Kirsten rat sarcoma virus oncogene homolog (KRAS), Harvey rat sarcoma virus carcinogenic homolog (HRAS) and nerve Blastoma rat sarcoma virus oncogene homolog (NRAS).

技术领域
本发明涉及新的一类八元含N杂环类化合物,具体涉及式(P)所示化合物及其药学上可接受的盐。
背景技术
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。

本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
除了盐的形式,本发明所提供的化合物还存在前药形式。本文所描述的化合物的前药容易地在生理条件下发生化学变化从而转化成本发明的化合物。此外,前体药物可以在体内环境中通过化学或生化方法被转换到本发明的化合物。

本发明的化合物可以存在特定的。除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键 异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。

可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚( 3H),碘-125( 125I)或C-14( 14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。
“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,取代基可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR) 0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,
Figure PCTCN2021101868-appb-000041
中连接基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成
Figure PCTCN2021101868-appb-000042
也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
Figure PCTCN2021101868-appb-000043

实验例2:化合物药代动力学评价
实验目的:
本实验目的是评价化合物单次静脉注射和灌胃给药后的药代动力学行为,考察灌胃给药后的生物利用度。
实验操作:
选取7至10周龄的CD-1雄性小鼠,静脉和口服给药的剂量分别为3毫克每公斤和10毫克每公斤。试验动物在整个试验期间自由饮食、饮水。
实验当天静脉组动物通过尾静脉单次注射给予化合物,给药体积为3mL/kg;口服组通过单次灌胃给予化合物,给药体积为10mL/kg。在给药前称量动物体重,根据体重计算给药体积。样品采集时间为:0.083(注射组)、0.25、0.5、1、2、4、8、24h。每个时间点通过隐静脉采集大约30μL全血用于制备血浆供高效液相色谱-串联质谱(LC-MS/MS)进行浓度测定。所有动物在采集完最后一个时间点的PK样品后进行CO 2麻醉安乐死。采用WinNonlin TM Version 6.3(Pharsight,Mountain View,CA)药动学软件的非房室模型处理血浆浓度,使用线性对数梯形法方法计算药动学参数。

细胞接种:将0.2mL(5×10 6cells/mouse个)Mia PaCa-2细胞(加基质胶,体积比为1:1)皮下接种于每只小鼠的右后背,肿瘤平均体积达到118mm 3时,根据肿瘤体积进行随机分组,每组6只,空白组给药剂量为0,测试组给药剂量分别为10mg/kg,给药体积10μL/g,口服给药,给药22天,每天一次。
2.肿瘤测量和实验指标
每周两次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为:V=0.5a×b 2,a和b分别表示肿瘤的长径和短径。
化合物的抑瘤疗效用TGI(%)或相对肿瘤增殖率T/C(%)评价。相对肿瘤增殖率T/C(%)=TRTV/CRTV×100%(TRTV:治疗组RTV;CRTV:阴性对照组RTV)。根据肿瘤测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为RTV=Vt/V0,其中V0是分组给药时(即D0)测量所得平均肿瘤体积,Vt为某一次测量时的平均肿瘤体积,TRTV与CRTV取同一天数据。
TGI(%),反映肿瘤生长抑制率。TGI(%)=[(1-(某处理组给药结束时平均瘤体积-该处理组开始给药 时平均瘤体积))/(溶剂对照组治疗结束时平均瘤体积-溶剂对照组开始治疗时平均瘤体积)]×100%。
