Description
本申请要求享有2018年9月30日向中国国家知识产权局提交的申请号为201811162497.1、发明名称为“取代吡唑稠环类衍生物及其制备方法和应用”的在先专利申请的优先权权益。该在先专利申请的全文以引用的方式结合至本文中。
技术领域
本发明涉及药物化学领域,具体涉及取代吡唑稠环类衍生物及其制备方法和应用。
背景技术
RET(Rearranged During Transfection)原癌基因最初是在1985年,通过NIH3T3(小鼠胚胎成纤维细胞系)细胞与人类淋巴瘤DNA的转染被证实(Cell,1985,42(2):581-588)。RET原癌基因定位于染色体10q11.2,其DNA全长为60kb,含有外显子21个,编码由1100个氨基酸组成的RET蛋白:这种RET蛋白是一种酪氨酸激酶受体,含有一个由半胱氨酸组成的细胞外区、一个跨膜区和一个具有催化酪氨酸激酶作用的细胞内区(Mol CellEndocrinol,2010,322(1-2):2-7)。RET参与细胞增殖、神经传导、细胞迁移和细胞分化,通过配体/复合受体/RET多蛋白复合物的信号,激活各种下游途径,如RAS/RAF/MEK/ERK,PI3K/AKT和STAT通路,诱导细胞增生(J Clin Oncol,2012,30(2):200-202)。
随着研究的逐步进展,现已发现多种疾病的发生与RET基因突变有密切联系,包括甲状腺乳头状癌(papillary thyroid carcinoma,PTC)(Cell,1990,60(4):557-563)、甲状腺髓样癌(medullary thyroid carcinoma,MTC)(hyroid,2009,19(6):565-612)、多发性内分泌腺瘤病2型(multiple endocrineneoplasia type II,MEN2)(Endocr Rev,2006,27(5):535-560)、先天性巨结肠(Proc Natl Acad Sci USA,2000,97(1):268-273)、肺腺癌(Nat Med,2012,18(3):375-377)等。目前只有KIF5B-RET、CCDC6-RET、TRIM33-RET、NCOA4-RET这四种RET融合基因在非小细胞肺癌中被报道,而KIF5B-RET是非小细胞肺癌中最常见的RET融合基因(Cancer,2013,119(8):1486-1494)。KIF5B-RET是KIF5B(kinesin familymember 5B)基因和RET基因的染色体倒置(p11;q11)形成的一种融合基因,通过全基因组和转录组测序,第一次在非吸烟韩国人的腺癌中被证实;KIF5B-RET在肺癌中的比例很低,在非吸烟者和腺癌患者中更常见,并与其它突变,如EGFR、KRAS、BRAF、ErbB2、EML4-ALK相排斥(Genome Res,2012,22(3):436-445)。KIF5B-RET融合蛋白包含马达结构域和KIF5B的卷曲螺旋结构域,通过卷曲螺旋结构域的二聚化作用,该融合蛋白的RET酪氨酸激酶活性可异常活化,从而促进肺肿瘤发生(Cancer,2011,117(12):2709-2718)。在Qian等的研究中(MolCancer,2014,13:176),KIF5B-RET融合激酶被证实在体外和体内都具有显着的致癌活性,STAT3的信号转导途径可能是肿瘤发生的主要下游介质。有证据显示KIF5B-RET可调节STAT3的持续活化。KIF5B-RET融合激酶可以结合STAT3,直接磷酸化和激活STAT3-Tyr705;它也可以通过JAK/STAT3依赖性途径,介导激活STAT3-Tyr705,并通过RAS/RAF/MEK/ERK1途径触发Ser727的磷酸化。
证明RET融合物在一些癌症中是驱动者,这件事促进了已具有RET抑制活性的多激酶抑制剂(multi-kinase inhibitor)的应用,用于治疗c负载RET融合物蛋白质的肿瘤病人。目前尚未有批准药剂可以用来针对性地靶向这一致癌基因,目前RET特异性癌症的治疗方式仅限于多激酶抑制剂和化疗,但这些非特异性治疗临床表现ORR(客观缓释率)不好并且有很大的脱靶毒性。再者,癌症治疗的最大挑战之一是肿瘤细胞对于治疗一定阶段后出现耐药,一旦耐药,病人的治疗方式通常极为有限,且大多数例子中,癌症一直进展、不受抑制。为了能在这方面获得突破,需要一些化合物可以选择性专门靶向致癌RET融合和基因突变。

作为药物时,可按药物组合物的形式给予本发明化合物。可按药剂领域中熟知的方式制备这些组合物,可通过多种途径给予它们,这取决于是否需要局部或全身治疗和所治疗的区域。可局部(例如,透皮、皮肤、眼和粘膜包括鼻内、阴道和直肠递药)、肺(例如,通过吸入或吹入粉末或气雾剂,包括通过喷雾器;气管内、鼻内)、口服或肠胃外给药。肠胃外给药包括静脉内、动脉内、皮下、腹膜内或肌内注射或输注;或颅内例如鞘内或脑室内给药。可按单次大剂量形式肠胃外给药,或可通过例如连续灌注泵给药。局部给予的药用组合物和制剂可包括透皮贴剂、软膏、洗剂、霜剂、凝胶剂、滴剂、栓剂、喷雾剂、液体剂和散剂。常规药物载体、水、粉末或油性基质、增稠剂等可能是必须的或需要的。包衣避孕套(Coatedcondoms)、手套等也可以是有用的。
在制备本发明的组合物时,通常将活性成分与赋形剂混合,通过赋形剂稀释或装入例如胶囊、小药囊、纸或其它容器形式的这种载体内。当赋形剂用作稀释剂时,它可以是固体、半固体或液体物质,用作溶媒、载体或活性成分的介质。因此,组合物可以是以下形式:片剂、丸剂、散剂、锭剂、小药囊、扁囊剂、酏剂、混悬剂、乳剂、溶液剂、糖浆剂、气雾剂(固体或溶于液体溶媒);含例如高达10%重量活性化合物的软膏剂、软和硬明胶胶囊、栓剂、无菌注射溶液和无菌包装粉末。

对于制备固体组合物例如片剂,将主要的活性成分与药物赋形剂混合,形成含本发明化合物的均匀混合物的固体预制剂组合物。当称这些预制剂组合物为均匀时,是指活性成分通常均匀地分布在整个组合物中,致使该组合物可容易地划分为同等有效的单位剂型例如片剂、丸剂和胶囊剂。然后将该固体预制剂划分为上述类型的含例如约0.1~1000mg本发明活性成分的单位剂型。
可将本发明片剂或丸剂包衣或复合,得到提供长效作用优点的剂型。例如,片剂或丸剂含内剂量和外剂量组分,后者是前者的被膜形式。可通过肠溶层将两种组分隔离,肠溶层用于在胃中阻止崩解,以使内组分完整通过十二指肠或延迟释放。多种物质可用于此类肠溶层或包衣剂,此类物质包括多种高分子酸和高分子酸与此类物质如虫胶、鲸蜡醇和醋酸纤维素的混合物。

给予患者的化合物或组合物的量不固定,取决于给予的药物、给药的目的例如预防或治疗;患者的状态、给药的方式等。在治疗应用时,可给予已患疾病的患者足够治愈或至少部分抑制疾病及其并发症症状的量的组合物。有效剂量应取决于所治疗的疾病状态和主治临床医师的判断,该判断取决于例如疾病的严重程度、患者的年龄、体重和一般状况等因素。
给予患者的组合物可以是上述药用组合物形式。可通过常规灭菌技术或可过滤灭菌,将这些组合物灭菌。可将水溶液包装原样使用,或冻干,给药前,将冻干制剂与无菌水性载体混合。化合物制剂的pH通常为3~11,更优选5~9,最优选7~8。可以理解,使用某些前述赋形剂、载体或稳定剂会导致形成药物盐。
本发明化合物的治疗剂量可根据例如以下而定:治疗的具体用途、给予化合物的方式、患者的健康和状态,以及签处方医师的判断。本发明化合物在药用组合物中的比例或浓度可不固定,取决于多种因素,它们包括剂量、化学特性(例如疏水性)和给药途径。例如可通过含约0.1~10%w/v该化合物的生理缓冲水溶液提供本发明化合物,用于肠胃外给药。某些典型剂量范围为约1μg/kg~约1g/kg体重/日。在某些实施方案中,剂量范围为约0.01mg/kg~约100mg/kg体重/日。剂量很可能取决于此类变量,如疾病或病症的种类和发展程度、具体患者的一般健康状态、所选择的化合物的相对生物学效力、赋形剂制剂及其给药途径。可通过由体外或动物模型试验系统导出的剂量-反应曲线外推,得到有效剂量。

表1
激酶活性测试
转染重组基因(RET)是一个已经确认的原癌基因。它编码的单次跨膜受体酪氨酸激酶,是许多组织和细胞类型的发育,成熟和维持所必需的。在正常条件下,神经胶质细胞系衍生的神经营养因子(GDNF)家族配体与细胞表面上的RET的结合导致细胞内酪氨酸残基的二聚化和自磷酸化。这反过来导致下游RAS-MAPK,PI3K-AKT和磷脂酶Cγ(PLCγ)通路的激活,并增加细胞存活和增殖。激活RET突变的实例包括C634W,M918T和关守突变,V804L和V804M。
该试验将肽底物和单一专有单克隆抗体与HTRF技术相结合,HTRF技术是一种高灵敏度和稳定的技术,用于检测蛋白质的分子相互作用。酶将底物磷酸化,然后Eu标记的抗体结合磷酸化底物,链霉抗生物素蛋白-XL665结合所有底物。TR-FRET信号由HTRF原理产生。一旦添加抑制剂(受试化合物),就获得较弱的TR-FRET信号。据此,评估抑制效果。

5.5数据分析
计算每个孔的比率(665nm/615nm)。
抑制率%通过如下方式计算:
抑制率%=[1-(受试化合物荧光信号值-阳性对照荧光信号值)/(阴性对照平均比率-阳性对照平均比率)]*100%
比率:由测得的荧光信号值产生
阳性对照平均比率为样品板中阳性对照(200nM AT13148)的平均比率;
阴性对照平均比率为样品板中阴性对照(0.1%DMSO)的平均比率。
利用GraphPad 6.0将抑制率%与化合物浓度的对数拟合为非线性回归(剂量响应-可变斜率)计算IC50值。
