Definitions

  • the invention belongs to the field of medicinal chemistry, and specifically relates to a pyridazine compound, its pharmaceutical composition and application.
  • Rat sarcoma protein is an important signaling regulator in the human body, regulating important physiological processes including cell proliferation, differentiation, migration and survival.
  • RAS belongs to guanosine triphosphate hydrolase (GTPase), which regulates downstream RAF/MEK/ through the recycling of the active state of RAS bound to guanosine triphosphate (GTP) and the inactive state of RAS bound to guanosine diphosphate (GDP).
  • GTPase guanosine triphosphate hydrolase
  • This cycle includes two processes, in which the negative regulation catalyzes the hydrolysis of RAS-GTP to RAS-GDP through GTPase activating protein (GAP), and the positive regulation guanylate exchange factor (GEF) catalyzes the dissociation of RAS and GDP, and then RAS Will bind to the high concentration of GTP in cells.
  • GAP GTPase activating protein

  • the RAS protein family includes KRAS (kirsten rat sarcoma viral oncogene), NRAS (neuroblastoma RAS viral oncogene) and HRAS (Harvey murine sarcoma viral oncogene), among which tumors caused by KRAS mutations are the most common. KRAS mutations cause the protein to remain in the RAS-GTP state, continuously activating downstream signaling pathways. SOS1 plays an important role in this carcinogenic physiological process. Knocking out SOS1 can effectively reduce the growth rate of KRAS mutant tumors and does not affect the growth of KRAS wild-type cell lines.
  • Small molecule inhibitors bind to the catalytic pocket of SOS1 and affect the binding of SOS1 to RAS proteins. They can effectively inhibit the phosphorylation levels of downstream RAS signaling pathways such as ERK (extracellular regulated protein kinases), thereby inhibiting tumor growth.

Abstract

Description

一种哒嗪类化合物、其药物组合物及应用 技术领域
本发明属于药物化学领域,具体涉及一种哒嗪类化合物、其药物组合物及应用。
背景技术
大鼠肉瘤蛋白(RAS蛋白)是人体内重要的信号传导调节因子,调控包括细胞增殖、分化、迁移和生存等重要生理过程。RAS属于三磷酸鸟苷水解酶(GTPase),通过RAS与三磷酸鸟苷(GTP)结合的活性状态和RAS与二磷酸鸟苷(GDP)结合的失活状体的循环调控下游RAF/MEK/ERK和PI3K/AKT等多条重要的信号通路。这一循环包括两个过程,其中负向调节通过GTPase激活蛋白(GAP)催化RAS-GTP水解为RAS-GDP,正向调节的鸟苷酸交换因子(GEF)催化RAS与GDP解离,随后RAS会与细胞内高浓度的GTP结合。SOS1(Son of Sevenless 1)是人体内表达最广泛,功能最重要的GEF之一。
RAS蛋白家族包括KRAS(kirsten rat sarcoma viral oncogene),NRAS(neuroblastoma RAS viral oncogene)和HRAS(Harvey murine sarcoma viral oncogene),其中KRAS突变导致的肿瘤最为常见。KRAS突变导致蛋白一直处于RAS-GTP的状态,持续激活下游信号通路,在这一致癌生理过程中SOS1扮演这重要的角色。敲除SOS1能有效降低KRAS突变肿瘤的生长速度,并且不影响KRAS野生型细胞系的生长。
小分子抑制剂结合在SOS1的催化口袋,影响SOS1与RAS蛋白的结合,可以有效的抑制RAS信号通路下游如ERK(extracellular regulated protein kinases)磷酸化水平,从而抑制肿瘤的生长。目前,勃林格殷格翰公司开发的小分子SOS1抑制剂BI-1701963(WO2018115380,WO2019122129)正处于I期临床研究阶段,并且与Mirati公司的KRAS G12C抑制剂MRTX-849合作开发联合用药的方案。此外,拜耳公司(WO2018172250,WO2019201848)和Revolution公司(WO2020180770,WO2020180768)也在这一领域发表了多篇专利,但是本领域仍然迫切需要研发出能够抑制SOS1与RAS突变蛋白相互作用的有效药物。
发明内容
本发明目的是提供一种新的哒嗪类化合物和包含其的药物组合物,其可以有效抑制SOS1与RAS突变蛋白相互作用。
本发明第一方面,提供一种式I所示的化合物、其药学上可接受的盐、对映异构体、非对映异构体、互变异构体、顺反异构体、溶剂化物、多晶型物、氘代物或其组合,
