Definitions

  • the present invention discloses a new class of biaryl compounds of Pan-RAF kinase inhibitors, and specifically discloses compounds represented by formula (III), or pharmaceutically acceptable salts thereof, and their usefulness in the treatment of cancer-related diseases application.
  • the mitogen-activated protein kinase (MAPK) pathway is an important signal transduction pathway in the cell, which transfers signals from outside the cell through the specific cascade phosphorylation of RAS/RAF/MEK/ERK In the cell nucleus, the activation of specific genes eventually leads to cell proliferation, apoptosis or differentiation. The excessive activation of this pathway is closely related to the occurrence of many kinds of tumors.
  • RAF is a very important serine/threonine protein kinase in the RAS/RAF/MEK/ERK signaling pathway. It is located downstream of RAS and can be activated by RAS.
  • the RAF family includes three subtypes, ARAF, BRAF, and CRAF (RAF-1), with high homology and similar domains.
  • Wild-type RAF can produce homo- or heterodimers of three subtypes. ARAF and CRAF mutations occur less frequently, and BRAF mutation rates are higher. About 5%-10% of malignant tumors, including 66% of melanoma patients, have BRAF mutations.
  • RAF kinase As a key signal protein downstream of RAS, RAF kinase has important research significance in the treatment of RAS mutant tumors. By inhibiting RAF kinase, it regulates MAPK signal transduction, thereby exerting an effect on the proliferation of RAS mutant tumor cells. Therefore, RAF kinase has become an important target for clinical treatment of tumors.
  • the first-generation BRAF kinase inhibitors Vemurafenib and Dabrafenib have been approved by the FDA for the treatment of cancers with B-Raf V600E mutations. Although Vemurafenib and Dabrafenib have shown promising effects in the treatment of B-Raf V600E mutant melanoma, they still have certain limitations. Most patients who use these two drugs initially shrink their tumors, but relapse within a year (acquired drug resistance); the main mechanism for this resistance is the reactivation of the MAPK signaling pathway. Studies have found that on the basis of the V600E mutation in BRAF, the NRAS mutation can cause the activation of the MAPK pathway in the presence of inhibitors, resulting in drug resistance.
  • the mutant N-Ras promotes the formation of homodimers or heterodimers between B-Raf V600E and C-Raf.
  • the inhibitor binds to a certain monomer of the dimer, it can reduce the affinity of the drug to another monomer, promote the phosphorylation of the monomer without inhibitor, and cause the activation of MEK.
  • the main method to overcome the drug resistance caused by the reactivation of the MAPK pathway is to block the two key sites of the MAPK pathway through the combined use of Raf and MEK inhibitors to delay the development of drug resistance.
  • the development of a new generation of pan-Raf inhibitors to overcome drug resistance and expand the scope of clinical applications is also under development.
  • Pan-RAF inhibitors can inhibit dimer activity and block paradoxcal activation of pathways. , Which can reduce drug resistance.
  • the pan-Raf dimer inhibitors under clinical research mainly include HM95573, TAK-580, BGB-283, LXH254, and LY3009120.
  • the development of these new RAF inhibitors is expected to overcome the resistance of the first-generation inhibitors , To further expand the clinical application.

技术领域
本发明公开了一类新的Pan-RAF激酶抑制剂的联芳基化合物,具体公开了式(III)所示化合物、或其药学上可接受的盐,以及它们在治疗与癌症相关疾病中的应用。
背景技术
丝分裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)通路是细胞内一条重要的信号转导通路,该通路通过RAS/RAF/MEK/ERK的特异性级联磷酸化将信号由细胞外传入细胞核内,最终导致特定基因的激活,引起细胞增殖、凋亡或分化。该通路过度激活与多种肿瘤的发生密切相关。RAF是RAS/RAF/MEK/ERK信号通路中一个非常重要的丝氨酸/苏氨酸蛋白激酶,位于RAS的下游,可以被RAS激活。RAF家族包括ARAF、BRAF、CRAF(RAF-1)三种亚型,具有高度的同源性和相似的结构域。野生型RAF能够产生三种亚型的同源或异源二聚体。ARAF和CRAF突变较少发生,BRAF突变率较高。约5%~10%的恶性肿瘤,包括66%的黑色素瘤患者存在BRAF突变。RAF激酶作为RAS下游的关键信号蛋白,在RAS突变基因突变肿瘤的治疗中具有重要的研究意义。通过抑制RAF激酶,调控MAPK信号传导,从而对RAS突变肿瘤细胞的增殖发挥作用。因此,RAF激酶已成为临床治疗肿瘤的重要靶标。
第一代BRAF激酶抑制剂Vemurafenib和Dabrafenib已经被FDA批准用于发生B-Raf V600E突变癌症的治疗。尽管Vemurafenib和Dabrafenib在B-Raf V600E突变黑色素瘤的治疗上表现出可喜的疗效,但依然存在一定的局限性。大多数使用这两种药物的患者起初肿瘤缩小,但在一年内复发(获得性耐药性);产生这一耐药的主要机制是MAPK信号通路被重新激活。研究发现在BRAF发生V600E突变的基础上,NRAS突变能够在抑制剂的存在下导致MAPK通路激活,产生耐药性。突变的N-Ras促进B-Raf V600E和C-Raf形成同源或异源二聚体。抑制剂结合在二聚体的某个单体上,可降低药物对另一个单体的亲和力,促进无抑制剂作用的单体磷酸化,导致MEK的激活。目前,临床上克服MAPK通路被重新激活导致耐药性的主要方法是通过联合使用Raf和MEK抑制剂阻断MAPK通路的2个关键位点,以延缓耐药性产生。除此之外,开发新一代pan-Raf抑制剂以克服耐药性以及扩展临床应用范围也正在开发中,pan-RAF抑制剂可以抑制二聚体活性,阻断通路的反常激活(paradoxcal activation),从而可以减耐药性。处于临床研究的的pan-Raf二聚体抑制剂主要有HM95573、TAK-580、BGB-283、LXH254,以及LY3009120等,这些新型RAF抑制剂的研发,有望克服第一代抑制剂的耐药性,进一步扩大临床应用。

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)。
“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,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,-C 0烷基-A表示该结构实际上是-A。
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。

2.1肿瘤细胞接种

注1:在给动物给药前需要轻轻将药物充分混匀,solutol为聚乙二醇-15-羟基硬脂酸酯。
2.4肿瘤测量和实验指标
每周两次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为:V=0.5a×b 2,a和b分别表示肿瘤的长径和短径。
化合物的抑瘤疗效用TGI(%)或相对肿瘤增殖率T/C(%)评价。相对肿瘤增殖率T/C(%)=T RTV/C RTV×100%(T RTV:治疗组RTV平均值;C RTV:阴性对照组RTV平均值)。根据肿瘤测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为RTV=V t/V 0,其中V 0是分组给药时(即D0)测量所得肿瘤体积,V t为某一次测量时的肿瘤体积,T RTV与C RTV取同一天数据。
TGI(%),反映肿瘤生长抑制率。TGI(%)=[1-(某处理组给药结束时平均瘤体积-该处理组开始给药时平均瘤体积)/(溶剂对照组治疗结束时平均瘤体积-溶剂对照组开始治疗时平均瘤体积)]×100%。
2.5统计分析
统计分析基于试验结束时RTV的数据运用SPSS软件进行分析。组间比较用one-way ANOVA进行分析,方差不齐(F值有显著性差异),应用Games-Howell法进行检验。p<0.05认为有显著性差异。
