Definitions

  • the present disclosure relates to a series of compounds containing hexahydrospirocycle [cyclopropane-1,2'-pyrrozine], specifically to the compound represented by formula (III), its stereoisomers and pharmaceutically acceptable salts thereof.
  • KRAS is one of the widely expressed RAS protein family members (KRAS, NRAS and HRAS). It participates in the transduction regulation of extracellular signals to intracellular downstream signals by binding to GTP (on) or GDP (off).
  • GTP on
  • GDP off
  • protein mutations It often destroys its own GTP hydrolase activity, causing its own long-term activation, causing excessive activation of downstream molecules, thereby promoting abnormal cell proliferation and the transformation of cancer cells.
  • Due to the shallow pocket of the KRAS protein and strong GTP binding ability cells contain a large amount of GTP. Therefore, even though researchers have been exploring for more than 30 years, they still cannot develop an effective KRAS targeted inhibitor, so that the KRAS gene is called “Untargetable” genes.
  • the G12D mutation is a relatively common subtype of KRAS gene mutations, which refers to the mutation of glycine (G) on No. 12 to aspartic acid (D).
  • KRAS G12D mutation is the most common in pancreatic cancer. According to the data reported in the literature (Nat Rev Drug Discov 2014; 13:828-851), about 46% of pancreatic cancer, 15% of colorectal cancer and 5% of non-small cell Lung cancer can develop KRAS G12D mutations.
  • KRAS G12D mutant protein As a cutting-edge target, KRAS G12D mutant protein has not yet entered clinical research with small molecule inhibitors, and only a few preclinical studies have been reported.
  • MIRATI THERAPEUTICS, INC published a patent for KRAS G12D small molecule inhibitors in 2021 (WO2021041671). The patent disclosed a series of pyridopyrimidine compounds with high KRAS G12D activity.

背景技术
KRAS是广泛表达的RAS蛋白家族成员(KRAS,NRAS和HRAS)之一,通过与GTP(开启)或GDP(关闭)结合的方式参与细胞外信号向胞内下游信号的转导调控,而蛋白突变往往破坏自身GTP水解酶活性,引起自身长时间激活,引发下游分子过度活化,从而促进细胞的异常增殖及癌细胞的转变。由于KRAS蛋白口袋较浅,GTP的结合能力强,细胞中却含有大量的GTP,因此即使研究者探索三十余年,依然无法开发出有效的KRAS靶向抑制剂,以至于KRAS基因被称为“不可靶向”基因。KRAS突变靶向治疗研究的徘徊不前,导致KRAS突变患者的治疗方案仍以传统放化疗为主,患者无法享受当今精准医疗的福利。近年来,随着药物研发技术的进步和新方法的涌现,国外KRAS G12C突变共价抑制剂被成功开发,这又重新点燃了科学家们直接靶向KRAS开发抑制剂的希望。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%。G12D突变是KRAS基因突变中比较常见的一个亚型,它是指12号甘氨酸(G)突变为天冬氨酸(D)。KRAS G12D突变在胰腺癌中最为常见,根据文献(Nat Rev Drug Discov 2014;13:828-851)报道的数据推算,约46%的胰腺癌、15%的结直肠癌和5%的非小细胞肺癌会发生KRAS G12D突变。
KRAS G12D突变蛋白作为一个前沿靶点,还没有小分子抑制剂进入临床研究,仅有很少的临床前研究被报道。MIRATI THERAPEUTICS,INC在2021年公开了一篇KRAS G12D小分子抑制剂的专利(WO2021041671),该专利公开了一系列具有高KRAS G12D活性的吡啶并嘧啶类化合物。

词语“包括(comprise)”或“包含(comprise)”及其英文变体例如comprises或comprising应理解为开放的、非排他性的意义,即“包括但不限于”。
术语“被置换”指特定的原子或基团可以被替换为指定的其他原子或基团。例如-CH2CH2CH2-中的1个或2个或3个-CH2-可被O、S、NH置换得到-O-CH2-CH2-、-O-CH2-、-CH2-O-CH2-、-CH2-O-、-CH2-CH2-O-、-O-等。
术语“任选”或“任选地”是指随后描述的事件或情况可以发生或不发生,该描述包括发生所述事件或情况和不发生所述事件或情况。例如,乙基“任选”被卤素取代,指乙基可以是未被取代的(CH2CH3)、单取代的(如CH2CH2F)、多取代的(如CHFCH2F、CH2CHF2等)或完全被取代的(CF2CF3)。本领域技术人员可理解,对于包含一个或多个取代基的任何基团,不会引入任何在空间上不可能存在和/或不能合成的取代或取代模式。
本公开中所述的“构型与化合物3-3A一致”是指,具有与化合物3-3A中六氢螺环[环丙烷-1,2'-吡咯嗪]部分一致的构型。例如化合物3的构型与化合物3-3A一致”是指,化合物3中六氢螺环[环丙烷-1,2'-吡咯嗪]部分的构型与化合物3-3A中六氢螺环[环丙烷-1,2'-吡咯嗪]部分的构型一致。
本公开的化合物可以存在特定的几何或立体异构体形式。本公开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公开的范围之内。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,均包括在本公开的范围之内。
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。

本公开的化合物和中间体还可以以不同的互变异构体形式存在,并且所有这样的形式包含于本公开的范围内。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。
本公开化合物可以具有一个或多个阻转异构体,除非另有说明,所述阻转异构体是指由于单键之间的自由旋转受阻而产生的光活性异构体。本公开的含有手性轴的化合物可以以外消旋形式被分离出来。当本 公开含有手性轴化合物的单键自由旋转的能垒足够高时,其阻转异构体可以以光活性纯的形式被分离出来。
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%。
本公开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。本公开的化合物的所有同位素组成的变换,无论放射性与否,都包括在本公开的范围之内。
本公开还包括与本文中记载的那些相同的,但一个或多个原子被原子量或质量数不同于自然中通常发现的原子量或质量数的原子置换的同位素标记的本公开化合物。可结合到本公开化合物的同位素的实例包括氢、碳、氮、氧、磷、硫、氟、碘和氯的同位素,诸如分别为2H、3H、11C、13C、14C、13N、15N、15O、17O、18O、31P、32P、35S、18F、123I、125I和36Cl等。
某些同位素标记的本公开化合物(例如用3H及14C标记的那些)可用于化合物和/或底物组织分布分析中。氚化(即3H)和碳-14(即14C)同位素对于由于它们易于制备和可检测性是尤其优选的。正电子发射同位素,诸如15O、13N、11C和18F可用于正电子发射断层扫描(PET)研究以测定底物占有率。通常可以通过与公开于下文的方案和/或实施例中的那些类似的下列程序,通过同位素标记试剂取代未经同位素标记的试剂来制备同位素标记的本公开化合物。
此外,用较重同位素(诸如氘(即2H))取代可以提供某些由更高的代谢稳定性产生的治疗优点(例如增加的体内半衰期或降低的剂量需求),并且因此在某些情形下可能是优选的,其中氘取代可以是部分或完全的,部分氘取代是指至少一个氢被至少一个氘取代。
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,比如A-L-Z中,连接基团L为-M-W-,此时表示该结构可以为A-M-W-Z或者A-W-M-Z。
除非另有规定,当某一基团具有一个或多个可连接位点时,该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的,且可连接位点存在H原子时,则连接化学键时,该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键直形虚线键或波浪线表示。例如-OCH3中的直形实线键表示通过该基团中的氧原子与其他基团相连;中的直形虚线键表示通过该基团中的氮原子的 两端与其他基团相连;中的波浪线表示通过该苯基基团中的1和2位碳原子与其他基团相连;表示该哌啶基上的任意可连接位点可以通过1个化学键与其他基团相连,至少包括 这4种连接方式,即使-N-上画出了H原子,但是仍包括这种连接方式的基团,只是在连接1个化学键时,该位点的H会对应减少1个变成相应的一价哌啶基;表示R可以任意连接在双键的两端,即表示当一个取代基的键交叉连接到一个环上的两个原子时,这种取代基可以与这个环上的任意原子相键合。例如,结构单元表示其可在环己基或者环己二烯上的任意一个位置发生取代。
除非另有规定,Cn-n+m或Cn-Cn+m包括n至n+m个碳的任何一种具体情况,例如C1-12包括C1、C2、C3、C4、C5、C6、C7、C8、C9、C10、C11、和C12,也包括n至n+m中的任何一个范围,例如C1-12包括C1- 3、C1-6、C1-9、C3-6、C3-9、C3-12、C6-9、C6-12、和C9-12等;同理,n元至n+m元表示环上原子数为n至n+m个,例如3-12元环包括3元环、4元环、5元环、6元环、7元环、8元环、9元环、10元环、11元环、和12元环,也包括n至n+m中的任何一个范围,例如3-12元环包括3-6元环、3-9元环、5-6元环、5-7元环、6-7元环、6-8元环、和6-10元环等。
