本发明涉及到一种作为MEK抑制剂的式(Ⅰ)化合物的多晶型、无定形及其制备方法和应用。The invention relates to a polymorphic form, an amorphous form of a compound of formula (I) as a MEK inhibitor, and a preparation method and application thereof.
背景技术Background technique
MAPK通路存在于细胞增殖,分化,凋亡与应激反应等一系列细胞进程中。目前已知的MAPK通路有四条:ERK1/2,JNK,p38与ERK5。其中最重要且最广为人知的MAPK通路之一,是Ras/Raf激酶通路。该通路首先由细胞外生长因子(即PDGF或EGF等)与跨膜受体(即PDGFR或EGFR或ErbB2等)结合,活化受体,而活化的受体通过鸟苷酸交换因子(如SOS)使膜内的Ras与GTP结合并活化;被激活的Ras进一步间接磷酸化并活化Raf(此通路中的MAPKKK);然后,活化的Raf在MEK1/2(此通路中的MAPKK)的两个丝氨酸残基上进行磷酸化(MEK1对应S218与S222;MEK2对应S222与S226)(Ahn et al.,Methods in Enzymology,2001,332,417-431)。磷酸化的ERK二聚后移向细胞核内并积聚(Khokhlatchev et al.,Cell,1998,93,605-615)。在细胞核内的ERK涉及到许多细胞功能,包括但不限于核转运,信号转导,DNA修复,核小体组装与迁移以及mRNA加工与翻译(Ahn et al.,Molecular Cell,2000,6,1343-1354)。MAPK pathway exists in a series of cellular processes such as cell proliferation, differentiation, apoptosis and stress response. There are currently four known MAPK pathways: ERK1/2, JNK, p38 and ERK5. One of the most important and well-known MAPK pathways is the Ras/Raf kinase pathway. The pathway is first activated by extracellular growth factors (ie PDGF or EGF, etc.) and transmembrane receptors (ie PDGFR or EGFR or ErbB2, etc.) to activate the receptors, and activated receptors through guanylate exchange factors (such as SOS) The Ras in the membrane is combined with GTP and activated; the activated Ras further indirectly phosphorylates and activates Raf (MAPKKK in this pathway); then, the activated Raf is at the two serines of MEK1/2 (MAPKK in this pathway) Phosphorylation of residues (MEK1 corresponds to S218 and S222; MEK2 corresponds to S222 and S226) (Ahn et al., Methods in Enzymology, 2001, 332, 417-431). Phosphorylated ERK dimerizes and moves into the nucleus and accumulates (Khokhlatchev et al., Cell, 1998, 93, 605-615). ERK in the nucleus involves many cellular functions, including but not limited to nuclear transport, signal transduction, DNA repair, nucleosome assembly and migration, and mRNA processing and translation (Ahn et al., Molecular Cell, 2000, 6, 1343 -1354).
RAF-MEK-ERK通路能传导由生长因子与致癌因子发出的增殖与抗凋亡信号,从而促进细胞的生长,发展与转移;若通路涉及的基因发生突变或生长因子、下游信号蛋白或蛋白激酶过表达,将会导致细胞增殖失控并最终导致肿瘤形成。举例来说,癌细胞突变引起生长因子过表达,从而导致其内部的MAPK通路的持续激活;或因突变导致激活的Ras复合物的无法去活化,同样也会造成MAPK通路的持续激活;近来,人们已从超过60%的黑素瘤中识别出bRaf变异(Davies,H.et al.,Nature,2002,417,949-954)。这些bRaf变异导致了自发活化的MAPK级联的产生。人们在胰腺癌,结肠癌,肺癌,卵巢癌与肾癌等原发性肿瘤样本与细胞系的研究中,也观察到了MAPK通路的自发性或者过度活化现象(Hoshino,R.et al.,Oncogene,1999,18,813-822)。因此,由于基因突变引起的MAPK通路过度活化与癌症之间有很强的相关性。The RAF-MEK-ERK pathway can transmit the proliferation and anti-apoptotic signals emitted by growth factors and oncogenic factors, thereby promoting cell growth, development and transfer; if the genes involved in the pathway are mutated or growth factors, downstream signaling proteins or protein kinases Overexpression will lead to uncontrolled cell proliferation and eventually tumor formation. For example, mutations in cancer cells cause overexpression of growth factors, which leads to the continuous activation of the internal MAPK pathway; or the inactivation of the activated Ras complex due to mutations can also cause the continuous activation of the MAPK pathway; recently, People have identified bRaf mutations in more than 60% of melanomas (Davies, H. et al., Nature, 2002, 417, 949-954). These bRaf mutations lead to the generation of spontaneously activated MAPK cascades. Spontaneous or excessive activation of the MAPK pathway has also been observed in studies of primary tumor samples and cell lines such as pancreatic cancer, colon cancer, lung cancer, ovarian cancer, and renal cancer (Hoshino, R. et al., Oncogene , 1999, 18, 813-822). Therefore, there is a strong correlation between excessive activation of the MAPK pathway due to gene mutations and cancer.
因为MAPK通路处于细胞增殖与分化中的中枢位置,抑制该通路将有利于治疗多种过度增殖疾病,而该通路中处于Ras与Raf下游的MEK则成为了该通路中的关键角色。此外,目前已知可由MEK磷酸化并激活的底物仅有MAPK,即ERK1与ERK2,这种严格的选择性及其双功能激酶独特能力,使其成为了很具吸引力的药物靶标,具有潜在而广泛的治疗应用,比如,恶性与良性过度增殖疾病,免疫调节与炎症。Because the MAPK pathway is central to cell proliferation and differentiation, inhibiting this pathway will be beneficial for the treatment of a variety of hyperproliferative diseases, and MEK in this pathway downstream of Ras and Raf has become a key role in this pathway. In addition, the only known substrates that can be phosphorylated and activated by MEK are MAPK, namely ERK1 and ERK2. This strict selectivity and the unique ability of its bifunctional kinase make it an attractive drug target. Potential and extensive therapeutic applications, such as malignant and benign hyperproliferative diseases, immunoregulation and inflammation.
针对MAPK信号通路,目前已有多个Raf和MEK抑制剂处于临床和上市阶段。如05年12月FDA批准上市的sorafenib(Bay 43-9006),是非特异性的丝/苏氨酸和酪氨酸激酶抑制剂,其作用靶点包含Raf,MEK,VEGFR2/3,Flt-3,PDGFR,c-Kit等。B-Raf特异性抑制剂如dabrafenib(GSK21 18436)和vemurafenib(PLX4032)均有良好的临床效果,但持续时间较短,且临床研究发现,B-Raf抑制剂的长期治疗会导致 患者产生获得性耐药性。因此,临床上常将MEK抑制剂与B-Raf抑制剂联用。特异性抑制MEK1/2抑制剂Trametinib(GSK-1 120212)已于2013年5月经FDA批准上市,并于2014年1月获批与dabrafenib联合治疗晚期黑色素瘤;特异性抑制MEK1/2抑制剂cobimetinib于2015年被FDA批准用于和vemurafenib联合用药,用于黑色素瘤治疗。Binimetinib在2016年,向FDA申请注册用于N-RAS突变的的黑色素瘤治疗。此外,还有Selumetinib,refametinibd等MEK1/2抑制剂处于临床阶段。In response to the MAPK signaling pathway, several Raf and MEK inhibitors are currently in clinical and marketing stages. For example, sorafenib (Bay 43-9006) approved by the FDA in December 2005 is a non-specific inhibitor of silk/threonine and tyrosine kinases, and its targets include Raf, MEK, VEGFR2/3, and Flt-3 , PDGFR, c-Kit, etc. B-Raf-specific inhibitors such as dabrafenib (GSK21 18436) and vemurafenib (PLX4032) have good clinical effects, but the duration is short, and clinical studies have found that long-term treatment of B-Raf inhibitors will lead to patient acquisition Drug resistance. Therefore, clinically often combined with MEK inhibitors and B-Raf inhibitors. Trametinib (GSK-1 120212), which specifically inhibits the MEK1/2 inhibitor, was approved by the FDA in May 2013 and was approved in January 2014 to be combined with dabrafenib for the treatment of advanced melanoma; it specifically inhibits the MEK1/2 inhibitor cobimetinib It was approved by the FDA in 2015 for use in combination with vemurafenib for melanoma treatment. In 2016, Binimetinib applied to the FDA for registration for the treatment of N-RAS mutant melanoma. In addition, Selumetinib, refametinibd and other MEK1/2 inhibitors are in clinical stage.
