Definitions
- the present application relates to novel pyrrolotriazine derivatives, processes for their preparation and pharmaceutical compositions comprising such derivatives and their use as therapeutic agents, in particular as c-KIT inhibitors.
- c-KIT also known as KIT, CD117 and stem cell factor receptor
- KIT c-KIT
- CD117 and stem cell factor receptor a transmembrane tyrosine kinase protein that acts as a type III receptor.
- the c-KIT proto-oncogene located on chromosome 4q11-21 encodes the c-KIT receptor and its ligand is a stem cell factor.
- the receptor has tyrosine protein kinase activity and binding to the ligand SCF results in autophosphorylation of c-KIT and its association with a substrate such as phosphatidylinositol 3-kinase (PI3K).
- PI3K phosphatidylinositol 3-kinase
- Phosphorylation of tyrosine by protein tyrosine kinases is particularly important in cell signaling and can mediate signals of major cellular processes such as proliferation, survival, differentiation, apoptosis, ligation, invasion and migration.
- c-KIT mutations are commonly found in DNA encoding the membrane proximal domain (exon 11). They also appear in exons 7, 8, 9, 13, 14, 17 and 18 at a lower frequency. Mutations make c-KIT function independent of activation by SCF, resulting in high cell division rates and possible genomic instability.
- c-KIT has been used in gastrointestinal stromal tumors, acute myeloid leukemia, systemic mastocytosis, melanoma, breast adenoma, ovarian tumor, cervical cancer, seminoma, dysplasia, teratoma, hypertrophy It has been found in tissues such as cell leukemia, and its protein expression level is closely related to the occurrence and development of tumors.
- Gastrointestinal stromal tumor GIST
- GIST Gastrointestinal stromal tumor
- the platelet-derived growth factor receptor is a cell surface tyrosine kinase receptor that is a member of the platelet-derived growth factor (PDGF) family.
- the PDGF subunits PDGF-A and PDGF-B are important regulators of cell proliferation, cell differentiation, cell growth, development, and many diseases including cancer.
- one of the objects of the present application is to provide a novel pyrrolotriazine derivative of the formula (I), or a stereoisomer, tautomer thereof or a pharmaceutically acceptable salt thereof.
- the compounds of the present application have large structural differences from the compounds disclosed in the prior art, and diseases such as gastrointestinal stromal tumors and systemic mastocytosis can be treated or prevented by modulating c-KIT activity.

Abstract
公开了吡咯并三嗪类衍生物、其制备方法及其在医药上的应用。具体而言,公开了式(I)的吡咯并三嗪类衍生物及其药学上可接受的盐、其制备方法以及它们作为治疗剂,特别是c-KIT抑制剂的用途,其中式(I)中的各取代基的定义与说明书中的定义相同。
Description
本申请涉及新型吡咯并三嗪类衍生物、其制备方法及包含该衍生物的药物组合物以及其作为治疗剂特别是作为c-KIT抑制剂的用途。
发明背景
c-KIT(也称为KIT、CD117和干细胞因子受体)是充当III型受体的145kDa跨膜酪氨酸激酶蛋白。位于染色体4q11-21上的c-KIT原癌基因编码c-KIT受体,其配体是干细胞因子。所述受体具有酪氨酸蛋白激酶活性并且与配体SCF的结合导致c-KIT的自磷酸化和其与底物如磷脂酰肌醇3-激酶(PI3K)的缔合。蛋白质酪氨酸激酶对酪氨酸的磷酸化在细胞信号传导方面特别重要并且可以介导主要细胞过程例如增殖、存活、分化、凋亡、连接、侵袭和迁移的信号。c-KIT突变通常出现在编码近膜区结构域的DNA(外显子11)中。它们还以较低频率出现在外显子7、8、9、13、14、17和18中。突变使得c-KIT功能不依赖于由SCF激活,从而导致高细胞分裂速率和可能的基因组不稳定性。c-KIT基因的功能增加性突变和组成性磷酸化c-KIT的表达可见于大部分胃肠间质瘤(GIST)、肥大细胞增多症和急性髓性白血病中。其在不同的外显子处有不同位置的突变,第一代的c-KIT突变和相关药物主要为伊马替尼、舒尼替尼、达沙替尼和PKC412。
c-KIT已在胃肠道间质瘤、急性髓性白血病、系统性肥大细胞增生症、黑色素瘤、乳腺瘤、卵巢瘤、宫颈癌、精原细胞瘤、无性细胞瘤、畸胎瘤、肥大细胞白血病等组织中被发现,其蛋白表达水平与肿瘤的发生发展有着密切的关系。其中胃肠间质瘤(gastrointestinal stromal tumor,GIST)是胃肠道最常见的间叶来源肿瘤,依照目前的GIST诊断标准,流行病学研究显示发病率为0.66-2.20/10万。GIST对传统化学治疗极不敏感,化疗药物有效率不足5%,进展期中位生存率仅约18个月。即使完整切除肿瘤,GIST的5年生存率也仅为35%-65%,2年内复发转移率为40%-50%,首诊时多达15%-50%的患者已存在转移。研究发现干细胞因子表面的跨膜酪氨酸激酶受体c-KIT和血小板源性生长因子受体PDGFRα基因的功能活化突变是GIST发生发展的关键。血小板源性生长因子受体(PDGF-R)是血小板源性生长因子(PDGF)家族成员的细胞表面酪氨酸激酶受体。PDGF亚基PDGF-A和PDGF-B是调控细胞增殖、细胞分化、细胞生长、发育和许多疾病包括癌症的重要调节因子。
随着第一代抑制剂伊马替尼(Imatinib)的临床应用,伊马替尼的获得性耐药问题逐渐成为该类抑制剂临床使用中面临的严重挑战。因此,迫切需要研究开发新的c-KIT抑制剂来满足市场需求。目前处于临床III期的c-KIT抑制剂药物包括Deciphera公司研发的ripretinib和Blueprint公司的Avapritinib。目前也已经公开了一系列的c-KIT抑制剂专利,其中包括WO2014039714、WO2014100620和WO2015134536A1等,c-KIT抑制剂的研究和应用已 取得一定的进展,但是提高的空间仍然巨大,仍有必要继续研究和开发新的c-KIT抑制剂。

测试化合物的最终浓度均在当天配制,再溶于细胞外液。
细胞外液(mM)为:NaCl,137;KCl,4;CaCl
2,1.8;MgCl
2,1;HEPES,10;glucose 10;pH 7.4(NaOH滴定)。所有测试化合物和对照化合物溶液均含0.3%DMSO。

3.4化合物的测试
化合物均采用利用自身重力的灌流系统进行灌流。每个浓度至少测试两个细胞。在电流稳定(或5分钟)后,再比较化合物使用前后的电流大小变化来计算化合物的阻断作用。
3.5阳性对照
阳性对照Cisapride浓度选择是根据它对细胞敏感性测试,阻断率90%左右的浓度为阳性对照最佳浓度。经测试Cisapride为100nM时,阻断率为90%左右,故阳性对照Cisapride定为100nM。方法和测试化合物一样。
3.6电生理
将细胞转移到灌流槽中,用细胞外液进行灌流。细胞内液(mM)为:K Aspartate,130;MgCl
2,5;EGTA 5;HEPES,10;Tris-ATP 4;pH 7.2(KOH滴定)。细胞内液分批少量储存于-80度冰箱,实验当天融化。电极用PC-10(Narishige,Japan)拉制。全细胞膜片钳记录,噪音 用采样频率的五分之一进行过滤。
3.7测试过程和结果
将细胞钳制在–80mV,然后用持续4秒方波去极化到40mV,再用持续2秒方波超极化到-40mV,以得到hERG尾电流(见附图1)。这一程序每20秒重复一次。hERG尾电流是纯hERG电流。检测第二个方波引发的最大电流,待其稳定后,灌流测试化合物,当反应稳定后,计算阻断的强度。具体IC
50见表3。具体见附图1。
