Definitions

  • the present invention relates to a novel nitrogen heterocyclic derivative, a process for the preparation thereof, a pharmaceutical composition containing the same, and its use as an SMO antagonist, particularly in the treatment of diseases associated with the Hedgehog signaling pathway, such as cancer .
  • Hedgehog (Hh) signaling pathway is an important embryonic pathway that plays an important regulatory role in cell proliferation and differentiation during embryonic development.
  • Hedgehog proteins that have been identified by humans: Sonic hedgehog (Shh), Indian hedgehog (Ihh), and Desert hedgehog (Dhh).
  • Sonic hedgehog (Shh) Sonic hedgehog
  • Ihh Indian hedgehog
  • Desert hedgehog (Dhh) Desert hedgehog
  • SMO seven-transmembrane protein Smoothened
  • PTCH-1 is a membrane protein with 12 transmembrane structures, which is a direct acting receptor for Shh. Under normal circumstances, the concentration of Hedgehog protein in the human body is very low. In this case, PTCH-1 interacts with SMO to inhibit the biological activity of SMO and put the channel in a closed state. Once Shh binds to PTCH-1, it will cause PTCH-1 to detach from SMO, thus freeing SMO from the suppressed state. Activation of SMO will further induce activation of downstream transcription factors Gli (including Gli1, Gli2 and Gli3), thereby regulating genes.
  • Gli downstream transcription factors
  • SMO acts as a switch for Gli. Disturbing its effects will induce excessive cell growth and canceration. For example, most basal cell carcinomas are hyperactive Hedgehog signaling pathways due to genetic mutations or other causes. Therefore, inhibition of the activity of the excessively high Hedgehog signaling pathway can inhibit the growth of cancer cells to achieve treatment of various cancers caused by this mechanism.
  • Hedgehog pathway antagonists Vismodegib (GDC-0449) and Sonidegib (LDE225) were approved by the US Food and Drug Administration (FDA) in 2012 and 2015, respectively, for the treatment of adult basal cell carcinoma patients. These antagonists inhibit the activity of SMO and inhibit the activity of the Hh signaling pathway, thereby achieving anticancer effects.
  • Hh signaling pathway In addition to basal cell carcinoma and medulloblastic cancer, many other cancers are also associated with abnormal activation of the Hh signaling pathway, including esophageal cancer, gastric cancer, pancreatic cancer, and lung cancer. Moreover, more and more studies have shown that the activity of the Hh signaling pathway is closely related to the problem of acquired resistance that is currently plagued by various cancer treatments. For example, the augmentation of the SMO gene and the activation of the Hh pathway are considered to be one of the main reasons for the loss of therapeutic effect on the cell epidermal growth factor receptor (EGFR) inhibitor of non-small cell lung cancer. Therefore, the development of Hedgehog inhibitors as anticancer drugs, especially in combination with other antibiotics to treat various cancers is very promising.
  • EGFR cell epidermal growth factor receptor
  • the inventors have deliberately studied and designed a series of nitrogen-containing heterocyclic compounds, and the results of in-depth studies show that the compounds can antagonize SMO and inhibit Hedgehog signaling pathway, and can be developed to treat Hedgehog signaling pathways.

Description

氮杂环类衍生物、其制备方法及其医药用途 技术领域
本发明涉及一种新的氮杂环类衍生物,其制备方法,含有其的药物组合物,以及其作为SMO拮抗剂的用途,特别是在治疗与Hedgehog信号通路相关的疾病如癌症中的用途。
背景技术
Hedgehog(Hh)信号通路是一条重要的胚胎通路,在胚胎发育的过程中对细胞增殖和分化中起到重要的调控作用。人类已经鉴别出来的同源Hedgehog蛋白有三种,分别是Sonic hedgehog(Shh)、Indian hedgehog(Ihh)和Desert hedgehog(Dhh)。许多证据显示Shh还在包括基底癌细胞等一些癌症的致癌机制上起着十分重要的作用。Hh信号借助与G蛋白偶联受体相关的七次跨膜蛋白Smoothened(SMO)传导。在成人体中,Hh信号通路一般处于关闭状态,但Hh信号通路的异常激活在肿瘤的发生和发展中起到了举足轻重的作用。基底癌细胞Hh信息通道的变异分析结果显示大多数的变异发生在PTCH-1和SMO上。PTCH-1是有着12次跨膜结构的膜蛋白,它是Shh的直接作用受体。在通常的情况下,人体内的Hedgehog蛋白的浓度非常低,在这种情况下,PTCH-1与SMO相作用,抑制SMO的生物活性,使该通道处于关闭状态。一旦Shh与PTCH-1结合,将导致PTCH-1脱离SMO,从而使SMO摆脱受抑制的状态,SMO的激活会进一步诱导下游的转录因子Gli(包括Gli1、Gli2和Gli3)的活化,从而调控基因的转录和细胞的生长。因此,SMO对Gli起着开关的作用。扰乱它的作用将诱发细胞的过度生长和癌变。比如大部分的基底细胞癌都是由于基因突变或其他原因导致的过高的Hedgehog信息传导通道活力。因此抑制过高的Hedgehog信息传导通路的活力能够抑制癌细胞的生长从而达到治疗由该机制引起的多种癌症。
近年来,Hedgehog通路的研究受到了科学界越来越多的重视,而靶向Hh通路尤其是新型靶点G蛋白偶联受体Smoothened(SMO)的小分子抑制剂已成为制药公司和科研机构的研究热点。其中Hedgehog通路拮抗剂Vismodegib(GDC-0449)和Sonidegib(LDE225)分别于2012年和2015年被美国食品药物管理局(FDA)批准上市,用于治疗成年基底细胞癌患者。这些拮抗剂抑制了SMO的活性,也就抑制了Hh信号通道活力,从而达到抗癌的作用。除了基底细胞癌和髓母细胞癌两种癌症,许多其他的癌症也和Hh信息传导通路异常激活有关,包括食管癌、胃癌、胰腺癌、肺癌等。不仅如此,越来越多的研究表明Hh信号通路的活性与当今困扰各种癌症治疗中的获得性耐药问题紧密相关。例如SMO基因的增扩及其Hh通路的活化被认为是令治疗非小细胞肺癌的细胞表皮生长因子受体(EGFR)抑制剂失去疗 效的主要原因之一。因此研发Hedgehog抑制剂作为抗癌药物,特别是与其它抗药物联合用药来治疗各种癌症前景非常广泛。
发明内容
本发明人经过潜心研究,设计合成了一系列含氮杂环类化合物,对其进行深入研究的结果显示该类化合物能够拮抗SMO从而抑制Hedgehog信号通路,并且可以被开发为治疗与Hedgehog信号通路相关的疾病的药物。
因此,本发明涉及一种式(I)所示的化合物或其内消旋体、外消旋体、对映异构体、非对映异构体、或其混合物形式、或其可药用盐,
