  • RAS protein is the product of RAS gene expression, which refers to a kind of closely related monomer globulin composed of 189 amino acids, with a molecular weight of 21KDa.
  • the active state of RAS protein has an important impact on cell growth, differentiation, cytoskeleton, protein transport and secretion.
  • the KRAS protein acts as a molecular switch to regulate the activation of downstream pro-proliferative effects by alternating between an inactive state bound by guanosine diphosphate (GDP) and an active state bound by guanosine triphosphate (GTP) protein.
  • GDP guanosine diphosphate
  • GTP guanosine triphosphate
  • KRAS protein will affect its interaction with GAP, which also affects its ability to hydrolyze GTP to GDP, making it always in an activated state.
  • the activated RAS protein continues to give downstream protein growth signals, which eventually leads to the continuous growth and differentiation of cells, and finally produces tumors.
  • RAS oncogene mutations are the most common activating mutations in human cancers, occurring in 30% of human tumors.
  • the RAS gene family contains three subtypes (KRAS, HRAS, and NRAS), 85% of RAS-driven cancers are caused by mutations in KRAS subtypes, which most commonly occur in solid tumors such as lung adenocarcinoma, pancreatic tube and colorectal cancer.

本发明涉及一类氟取代的嘧啶并吡啶类化合物及其应用,具体公开了式(IV)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。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重要的影响。在生长因子信号通路中,KRAS蛋白作为一个分子开关,通过在鸟苷二磷酸(GDP)结合的非活性状态和鸟苷三磷酸(GTP)结合的活性状态之间交替来调控激活下游促增殖效应蛋白。KRAS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癌基因突变是人类癌症中最常见的激活突变,发生在30%的人类肿瘤中。尽管RAS基因家族包含三种亚型(KRAS、HRAS和NRAS),但85%的RAS驱动型癌症是由KRAS亚型突变引起的,这种突变最常发生于实体肿瘤,如肺腺癌、胰管癌和结直肠癌。在KRAS突变型肿瘤中,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突变占所有KRAS突变的83%,最常见的突变为G12D(41%)、G12V(28%)和G12C(14%)。
近年来,人们利用KRAS G12C突变体12位半胱氨酸巯基的反应活性开展了其共价抑制剂的研究,并取得了较大的进展。目前对于KRAS G12D的研究都还处于临床前阶段。

定义和说明
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、 硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
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。
除非另有说明,术语“异构体”意在包括几何异构体、顺反异构体、立体异构体、对映异构体、旋光异构体、非对映异构体和互变异构体。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。
除非另有说明,“(+)”表示右旋,“(-)”表示左旋,“(±)”表示外消旋。

除非另有说明,当化合物中存在双键结构,如碳碳双键、碳氮双键和氮氮双键,且双键上的各个原子均连接有两个不同的取代基时(包含氮原子的双键中,氮原子上的一对孤对电子视为其连接的一个取代基),如果该化合物中双键上的原子与其取代基之间用波浪线
Figure PCTCN2022094274-appb-000057
连接,则表示该化合物的(Z)型异构体、(E)型异构体或两种异构体的混合物。例如下式(A)表示该化合物以式(A-1)或式(A-2)的单一异构体形式存在或以式(A-1)和式(A-2)两种异构体的混合物形式存在;下式(B)表示该化合物以式(B-1)或式(B-2)的单一异构体形式存在或以式(B-1)和式(B-2)两种异构体的混合物形式存在。下式(C) 表示该化合物以式(C-1)或式(C-2)的单一异构体形式存在或以式(C-1)和式(C-2)两种异构体的混合物形式存在。
Figure PCTCN2022094274-appb-000058
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%。
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体过量(ee值)为80%。
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。
术语“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。
当一个取代基数量为0时,表示该取代基是不存在的,比如-A-(R) 0表示该结构实际上是-A。
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。
当一个取代基的键可以交叉连接到一个环上的两一个以上原子时,这种取代基可以与这个环上的任意原子相键合,例如,结构单元
Figure PCTCN2022094274-appb-000059
表示其取代基R可在环己基或者环己二烯上的任意一个位置发生取代。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,

选取7至10周龄的CD-1雄性小鼠,静脉和腹腔注射给药的剂量分别为1毫克每公斤和2毫克每公斤,试验动物给药前需禁食一夜。
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0.667mL/kg;腹腔组通过单次注射给予化合物,给药体积为2mL/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25μL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。
