本发明涉及新颖的杂环化合物,其用于预防或治疗与STAT蛋白,特别是STAT3蛋白的活化有关的疾病的用途,以及包含所述化合物的药物组合物。
背景技术
STAT(信号转导子和转录激活子(signal transducer and activator oftranscription))蛋白是将多种细胞外细胞因子和生长因子的信号转导至细胞核的转录因子。当前已知STAT蛋白的七(7)个亚型(STAT1,STAT2,STAT3,STAT4,STAT5a,STAT5b,STAT6),并且通常它们由大约750-850个氨基酸组成。此外,STAT蛋白的每个亚型都包含几个保守结构域,这些结构域在发挥STAT蛋白功能方面起着重要作用。具体地,已经报道了从STAT蛋白的N末端到C末端的五(5)个结构域,包括卷曲螺旋结构域,DNA结合结构域,接头结构域,SH2结构域和反式激活结构域(TAD)。此外,自1998年以来,就报道了STAT1,STAT3,STAT4和STAT5的X射线晶体结构(Becker S等人,Nature,1998,394;Vinkemeier U等人,Science,1998,279;Chen X等人,Cell,1998,93;D.Neculai等人,J.Biol.Chem.,2005,280)。通常,与细胞因子和生长因子结合的受体被分类为I类和II类。IL-2,IL-3,IL-5,IL-6,IL-12,G-CSF,GM-CSF,LIF,血小板生成素等与I类受体结合,而INF-α,INF-γ,IL-10等与II类受体结合(Schindler C等人,Annu.Rev.Biochem.,1995,64;Novick D等人,Cell,1994,77;Ho AS等人,Proc.Natl.Acad.Sci.,1993,90)。其中,参与STAT蛋白活化的细胞因子受体可以根据其胞外结构域的结构形式分为gp-130家族,IL-2家族,生长因子家族,干扰素家族和受体酪氨酸激酶家族。白介素-6家族细胞因子是介导各种生理活性的代表性多功能细胞因子。当IL-6与细胞膜表面上存在的IL-6受体结合时,它会吸引gp-130受体形成IL-6-gp-130受体复合物。此时,细胞质中的JAK激酶(JAK1,JAK2,JAK3和Tyk2)被募集到gp130的细胞质区域进行磷酸化和活化。随后,潜在的胞质STAT蛋白被吸引到受体,被JAK激酶磷酸化并被活化。与位于STAT蛋白C末端的SH2结构域相邻的酪氨酸-705被磷酸化,并且每个STAT蛋白单体的活化的酪氨酸-705以相互交换的方式与另一个单体的SH2结构域结合,从而形成同型或异二聚体。二聚体易位于细胞核中并与特定的DNA结合启动子结合以促进转录。通过其转录过程,各种蛋白质(Myc,Cyclin D1/D2,BCLxL,Mcl,survivin,VEGF,HIF1,免疫抑制因子等)通过转录过程(Stark等人,Annu.Rev.Biochem.,1997,67;Levy等人,Nat.Rev.Mol.Cell Biol.,2002,3)。
特别是,已知STAT3蛋白在急性炎症反应和IL-6和EGF的信号转导途径中起关键作用(Akira等人,Cell,1994,76;Zhong等人,Science,1994,264)。根据最近的临床报道,在具有发生在前列腺,胃,乳腺,肺,胰腺,肾,子宫,卵巢,头颈中的实体癌的患者以及具有血液癌例如急性和慢性白血病,多发性骨髓瘤等的患者中,STAT3蛋白被持续活化。此外,据报道,STAT3被活化的患者组的存活率明显低于STAT3被灭活的患者组的存活率(Masuda等人,Cancer Res.,2002,62;Benekli等人,Blood,2002,99;Yuichi等人,Int.J.Oncology,2007,30)。同时,在采用STAT3基因敲除小鼠模型的研究中,STAT3被确定为鼠胚胎干细胞生长和维持的重要因素。此外,一项针对组织特异性STAT3缺陷小鼠模型的研究表明,STAT3以组织特异性方式在细胞生长,凋亡和细胞运动中起着重要作用(Akira等人,Oncogene 2000,19)。此外,由于在各种癌细胞系中都观察到了由反义(anti-sensing)STAT3诱导的凋亡,因此STAT3被认为是有希望的新抗癌靶标。STAT3也被认为是治疗糖尿病,免疫系统疾病,丙型肝炎,黄斑变性,乳头状瘤病毒感染,非霍奇金淋巴瘤和结核病患者的潜在靶标。与此相反,STAT1通过相同的细胞因子和生长因子增加炎症,先天性和获得性免疫,同时共享相同细胞因子和生长因子的细胞内下行途径,从而在大多数情况下导致抗增殖或促凋亡反应。因此,已知STAT1与STAT3起相反的作用(Valeria Poli等人,Review,Landes Bioscience,2009)。
STAT3抑制剂的开发策略可大致分为:i)通过IL-6/gp-130/JAK激酶抑制STAT3蛋白的磷酸化,ii)直接抑制活化的STAT3的二聚化,以及iii)抑制STAT3二聚体与STAT3细胞核中的DNA的结合。
作为正在研发的小分子STAT3抑制剂,据报道,由Otsuka Pharmaceutical Co.,Ltd.开发的OPB-31121,OPB-51602和OPB-111077正在针对实体瘤和血液癌患者进行临床试验,而S3I-201(Siddiquee等人,Proc.Natl.Acad.Sci.,2007,104),S3I-M2001(Siddiquee等人,Chem.Biol.,2007,2),LLL-12(Lin等人,Neoplasia,2010,12),Stattic(Schust等人,Chem.Biol.2006,13),STA-21(Song等人,Proc.Natl.Acad.Sci.,2005,102),SF-1-066(Zhang等人,Biochem.Pharm.,2010,79)和STX-0119(Matsuno等人,ACS Med.Chem.Lett.,2010,1)等据报道在癌细胞生长抑制实验和动物模型(体内异种移植模型)中是有效的。此外,尽管研究了模仿与SH2结构域结合位点相邻的pY-705(STAT3)氨基酸序列或与JAK激酶结合的gp-130受体氨基酸序列的肽化合物(Turkson J等人,Mol Cancer Ther.2004,261,Coleman等人,J.Med.Chem.,2005,48),但由于诸如溶解度和膜渗透性的问题,肽化合物的开发尚未成功。
