Definitions

  • the present invention relates to the field of medical technology, in particular to compounds used as RET kinase inhibitors, and their application in regulating RET kinase activity or treating RET-related diseases.
  • the RET (Rearranged during transfection, rearrangement during transfection) gene is located on chromosome 10.
  • the RET protein it encodes is a receptor tyrosine kinase (RTK) that exists on the cell membrane.
  • RTK receptor tyrosine kinase
  • Its mutation types mainly include KIF5B, Fusion mutations in genes such as TRIM33, CCDC6 and NCOA4, and point mutations in M918T.
  • Common RET mutations mainly occur in many types of cancers such as thyroid cancer and non-small cell lung cancer.
  • the incidence of RET gene fusion in NSCLC patients is about 1% to 2%, and the incidence in papillary thyroid cancer (accounting for about 85% of all thyroid cancers) is 10% to 20%.
  • RET fusion occurs in young patients.
  • the current treatment plan for RET gene modification is mainly to use multi-kinase inhibitor drugs, such as cabozantinib and vandetanib. Due to the low targeting, severe toxicity related to VEGFR inhibition usually occurs due to off-target.
  • Blueprint and Loxo Oncology announced their development of efficient and selective oral RET inhibitors BLU-667 and LOXO-292.
  • Blueprint Phase I clinical data showed that BLU-667 exhibits extensive anti-tumor activity.
  • the overall response rate (ORR) in tumor patients with RET fusion and mutation is 45%.
  • patients with non-small cell lung cancer and medullary thyroid cancer ORR is 50% and 40%, respectively.
  • Loxo Oncology's research drug LOXO-292 breakthrough therapy designation for the treatment of non-small cell lung cancer (NSCLC) and medullary thyroid cancer (MTC) patients with RET gene mutations.

Description

用作RET激酶抑制剂的化合物及其应用 技术领域
本发明涉及医药技术领域,具体涉及用作RET激酶抑制剂的化合物,及其在调节RET激酶活性或治疗RET相关疾病方面的应用。
背景技术
RET(Rearranged during transfection,转染期间重排)基因位于10号染色体,它所编码的RET蛋白是一种存在于细胞膜上的受体酪氨酸激酶(RTK),其变异类型主要包括与KIF5B、TRIM33、CCDC6和NCOA4等基因的融合突变,以及M918T等位点的点突变。人们常见的RET突变主要发生在甲状腺癌、非小细胞肺癌等多种癌症类型里。RET基因融合在NSCLC患者中的发生率约为1%~2%,在甲状腺乳头状癌(占所有甲状腺癌的85%左右)中的发生率为10%~20%,RET融合在年轻患者中更为常见,特别是年轻的非吸烟肺腺癌患者,发生率高达7%~17%。目前对于RET基因改变的治疗方案主要是使用多激酶抑制剂类药物,比如卡博替尼、凡德他尼,由于靶向性不高,通常会发生脱靶导致的VEGFR抑制相关的严重毒性。
蓝图药品公司(Blueprint)和莱德克斯制药公共有限公司(Loxo Oncology)公布了其开发的高效且具有选择性的口服RET抑制剂BLU-667和LOXO-292。Blueprint I期临床数据结果显示BLU-667表现出广泛的抗肿瘤活性,在具有RET融合和突变的肿瘤患者中总体缓解率(ORR)为45%,其中非小细胞肺癌和甲状腺髓样癌患者的ORR分别为50%和40%。最近美国FDA授予Loxo Oncology公司的在研药物LOXO-292突破性疗法认定,用于治疗携带RET基因变异的非小细胞肺癌(NSCLC)和甲状腺髓样癌(MTC)患者。
无论是BLU-667还是LOXO-292,目前还均处于临床试验阶段。因此,开发新的具有RET激酶抑制活性的、具有更好药效学、药代动力学性能的化合物已成为开发新型抗肿瘤药物的重要研究项目,并最终用于人类肿瘤等疾病的治疗中。

本发明中的化合物可能形成的盐也是属于本发明的范围。除非另有说明,本发明中的化合物被理解为包括其盐类。在此使用的术语“盐”,指用无机或有机酸和碱形成酸式或碱式的盐。此外,当本发明中的化合物含一个碱性片段时,它包括但不限于吡啶或咪唑,含一个酸性片段时,包括但不限于羧酸,可能形成的两性离子(“内盐”)包含在术语“盐”的范围内。药学上可接受的(即无毒,生理可接受的)盐是首选,虽然其他盐类也有用,例如可以用在制备过程中的分离或纯化步骤。本发明的化合物可能形成盐,例如,化合物I'与一定量如等当量的酸或碱反应,在介质中盐析出来,或在水溶液中冷冻干燥得来。
本发明中的化合物含有的碱性片段,包括但不限于胺或吡啶或咪唑环,可能会和有机或无机酸形成盐。可以成盐的典型的酸包括醋酸盐(如用醋酸或三卤代醋酸,如三氟乙酸)、己二酸盐、藻朊酸盐、抗坏血酸盐、天冬氨酸盐、苯甲酸盐、苯磺酸盐、硫酸氢盐、硼酸盐、丁酸盐、柠檬酸盐、樟脑盐、樟脑磺酸盐、环戊烷丙酸盐、二甘醇酸盐、十二烷基硫酸盐、乙烷磺酸盐、延胡索酸盐、葡庚糖酸盐、甘油磷酸盐、半硫酸盐、庚酸盐、己酸盐、盐酸盐、氢溴酸盐、氢碘酸盐、羟基乙磺酸盐(如,2-羟基乙磺酸盐)、乳酸盐、马来酸盐、甲磺酸盐、萘磺酸盐(如,2-萘磺酸盐)、烟酸盐、硝酸盐、草酸盐、果胶酸盐、过硫酸盐、苯丙酸盐(如3-苯丙酸盐)、磷酸盐、苦味酸盐、新戊酸盐、丙酸盐,水杨酸盐、琥珀酸盐、硫酸盐(如与硫酸形成的)、磺酸盐、酒石酸盐、硫氰酸盐、甲苯磺酸盐如对甲苯磺酸盐、十二烷酸盐等等。

本发明中的化合物、盐或溶剂合物,可能存在的互变异构形式(例如酰胺和亚胺醚)。所有这些互变异构体都是本发明的一部分。
所有化合物的立体异构体(例如,那些由于对各种取代可能存在的不对称碳原子),包括其对映体形式和非对映形式,都属于本发明的设想范围。本发明中的化合物独立的立体异构体可能不与其他异构体同时存在(例如,作为一个纯的或者实质上是纯的光学异构体具有特殊的活性),或者也可能是混合物,如消旋体,或与所有其他立体异构体或其中的一部分形成的混合物。本发明的手性中心有S或R两种构型,由理论与应用化学国际联合会(IUPAC)1974年建议定义。外消旋形式可通过物理方法解决,例如分步结晶,或通过衍生为非对映异构体分离结晶,或通过手性柱色谱法分离。单个的光学异构体可通过合适的方法由外消旋体得到,包括但不限于传统的方法,例如与光学活性酸成盐后再结晶。
本发明中的化合物,依次通过制备、分离纯化获得的该化合物其重量含量等于或大于90%,例如,等于或大于95%,等于或大于99%(“非常纯”的化合物),在正文描述列出。此处这种“非常纯”本发明的化合物也作为本发明的一部分。
本发明的化合物所有的构型异构体都在涵盖的范围之内,无论是混合物、纯的或非常纯的形式。在本发明化合物的定义包含顺式(Z)和返式(E)两种烯烃异构体,以及碳环和杂环的顺式和反式异构体。
在整个说明书中,基团和取代基可以被选择以提供稳定的片段和化合物。
特定官能团和化学术语定义都详细介绍如下。对本发明来说,化学元素与Periodic Table of the Elements,CAS version,Handbook of Chemistry and Physics,75 th Ed.中定义的一致。特定官能团的定义也在其中描述。此外,有机化学的基本原则以及特定官能团和反应性在“Organic Chemistry”,Thomas Sorrell,University Science Books,Sausalito:1999,也有说明,其全部内容纳入参考文献之列。
本发明的某些化合物可能存在于特定的几何或立体异构体形式。本发明涵盖所有的化合物,包括其顺式和反式异构体、R和S对映异构体、非对映体、(D)型异构体、(L)型异构体、外消旋混合物和其它混合物。另外不对称碳原子可表示取代基,如烷基。所有异构体以及它们的混合物,都包涵在本发明中。
按照本发明,同分异构体的混合物含有异构体的比率可以是多样的。例如,在只有两个异构体的混合物可以有以下组合:50:50,60:40,70:30,80:20,90:10,95:5,96:4,97:3,98:2,99:1,或100:0,异构体的所有比率都在本发明范围之内。本专业内一般技术人员容易理解的类似的比率,及为更复杂的异构体的混合物的比率也在本发明范围之内。
本发明还包括同位素标记的化合物,等同于原始化合物在此公开。不过实际上对一个或更多的原子被与其原子量或质量序数不同的原子取代通常会出现。可以列为本 发明的化合物同位素的例子包括氢、碳、氮、氧、磷、硫、氟和氯同位素,分别如 2H、 3H、 13C、 11C、 14C、 15N、 18O、 17O、 31P、 32P、 35S、 18F和 36Cl。本发明中的化合物,或对映体,非对映体,异构体,或药学上可接受的盐或溶剂化物,其中含有上述化合物的同位素或其他同位素原子都在本发明的范围之内。本发明中某些同位素标记化合物,例如 3H和 14C的放射性同位素也在其中,在药物和底物的组织分布实验中是有用的。氚,即 3H和碳-14,即 14C,它们的制备和检测比较容易。是同位素中的首选。此外,较重同位素取代如氘,即 2H,由于其很好的代谢稳定性在某些疗法中有优势,例如在体内增加半衰期或减少用量,因此,在某些情况下可以优先考虑。同位素标记的化合物可以用一般的方法,通过用易得的同位素标记试剂替换为非同位素的试剂,用批露在示例中的方案可以制备。
如果要设计一个本发明的化合物特定的对映体的合成,它可以不对称合成制备,或用手性辅剂衍生化,将所产生的非对映混合物分离,再除去手性辅剂而得到纯的对映体。另外,如果分子中含有一个碱性官能团,如氨基酸,或酸性官能团,如羧基,可以用合适的光学活性的酸或碱的与之形成非对映异构体盐,再通过分离结晶或色谱等常规手段分离,然后就得到了纯的对映体。
如本文所述,本发明中的化合物可与任何数量取代基或官能团取而扩大其包涵范围。通常,术语“取代”不论在术语“可选”前面或后面出现,在本发明配方中包括取代基的通式,是指用指定结构取代基,代替氢自由基。当特定结构中的多个在位置被多个特定的取代基取代时,取代基每一个位置可以是相同或不同。本文中所使用的术语“取代”包括所有允许有机化合物取代。从广义上讲,允许的取代基包括非环状的、环状的、支链的非支链的、碳环的和杂环的,芳环的和非芳环的有机化合物。在本发明中,如杂原子氮可以有氢取代基或任何允许的上文所述的有机化合物来补充其价态。此外,本发明是无意以任何方式限制允许取代有机化合物。本发明认为取代基和可变基团的组合在以稳定化合物形式在疾病的治疗上是很好的。此处术语“稳定”是指具有稳定的化合物,在足够长的时间内检测足以维持化合物结构的完整性,最好是在足够长的时间内都在效,本文在此用于上述目的。
本申请所涉及的化合物及其药学可接受的盐的代谢产物,以及可以在体内转变为本申请所涉及的化合物及其药学可接受的盐的结构的前药,也包含在本申请的权利要求中。
