Description
技术领域
本发明属于化学及生物医药技术领域,具体涉及一种新骨架的酰胺类衍生物、其制备方法及用途
背景技术
Kv7钾通道是一类电压依赖性钾离子通道,具有低阈值激活、慢激活和非失活的特点。Kv7钾通道具有五个家族成员(Kv7.1-Kv7.5,或称KCNQ1-KCNQ5),所有的Kv7钾通道成员具有相似的结构,即由四个亚基组成一个功能性通道,每个亚基包含六个跨膜片段(S1-S6)。其S1-S4是电压感受区,在感受膜电位变化和控制构象改变等方面具有重要作用;S5-S6是通道孔区的主要组成部分,是钾通道开放剂的主要组合和作用区域。KV7.1钾通道是一种非神经元通路,分布于外周组织,在心脏中表达,以介导心肌Iks,其突变可导致Long Q-T综合征。Kv7.2-Kv7.5钾通道是神经元M电流的基础,广泛分布于神经系统中,具有多种生理活性。电压门控钾离子通道KCNQ2主要在神经系统中表达,它与电压门控钾离子通道KCNQ3组装成异源四聚体,共同介导M-current(IKM)。IKM是一种慢激活、慢去活和非失活的电流,在维持静息膜电位、减少兴奋性刺激所触发的内在放电和重复动作电位放电方面发挥重要作用。1998年首次在良性家族性新生儿惊厥患者家族中发现了KCNQ2基因突变,揭示了KCNQ2通道与癫痫疾病的相关性。大量的临床研究发现,KCNQ2基因突变与癫痫、良性家族性新生儿惊厥或新生儿癫痫性脑病、周围神经过度兴奋(PNH或肌强直或神经性肌强直)等疾病的发作有关。KCNQ2通道在痛觉感受传导通路的各级神经元以及涉及疼痛的大脑区域表达则提示KCNQ2通道作为镇痛靶点的可能性。功能实验证明在神经性疼痛、骨关节炎疼痛、骨癌痛等模型中,KCNQ2表达量下调,激活KCNQ2通道可缓解神经性疼痛和纤维肌痛。此外,KCNQ2通道活性的调控还与帕金森病、缺血、精神分裂症、平滑肌疾病和抑郁等神经疾病相关。鉴于IKM在中枢和外周神经系统中控制神经元兴奋性方面具有的重要作用,KCNQ2通道被认为是神经系统疾病和代谢性疾病新药开发的重要药理靶点,开发KCNQ2通道调节剂对于治疗疼痛、癫痫或神经性疾病具有潜在应用价值。KCNQ4钾通道高度表达于耳蜗和脑干听觉核的外毛细胞,其突变可能导致遗传性耳聋。KCNQ5钾通道在骨骼肌和脑中高度表达,其突变可能导致视网膜病变等。
瑞替加滨是钾离子通道的激动剂,作为一种新型的抗癫痫药物用于辅助治疗部分发作性癫痫在2011年被批准上市,但其靶点选择性差会引起一系列副作用如视网膜色素沉积、皮肤变色和尿潴留等。BMS-204352、ICA-069673、NH29、ZnPy、ML213等一系列具有不同骨架的化合物被报道可以激活KCNQ2通道,在小鼠癫痫发作模型中部分化合物显示抗惊厥作用,但目前仍缺乏大量的临床前资料,考虑到这些新分子中绝大多数尚未开始临床试验,或者像ICA-069673这样已经进入临床II期研究的分子,因为耐受性和药代动力学等原因未能进行下一步临床研究,目前还无法预测它们是否会成功进入市场。
发明内容
目前,市场上除了瑞替加滨,虽然已有许多钾离子通道的小分子激动剂被发现,但是尚无其他成功上市的产品。通过计算机辅助药物设计结合理性设计和改造的方法,我们发现了一类具有成药前景的新骨架钾通道的小分子调节剂,并完成了体内外活性的相关研究。为了解决现有技术的上述问题,发明人经过锐意研究,深入探索,开发了一种具有钾通道调节剂的作用的化合物,并对其药理活性进行了深入测试。

如本文所用,化合物的“有效量”是指足以激动钾离子通道的量。

本发明中立体化学的定义和惯例的使用通常参考以下文献:
S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-HillBook Company,New York;and Eliel,E.and Wilen,S.,"Stereochemistry ofOrganic Compounds",John Wiley&Sons,Inc.,New York,1994.本发明的化合物可以包含不对称中心或手性中心,因此存在不同的立体异构体。本发明的化合物所有的立体异构形式,包括但绝不限于,非对映体,对映异构体,阻转异构体,和它们的混合物,如外消旋混合物,组成了本发明的一部分。非对映异构体可以以其物理化学差异为基础,通过层析、结晶、蒸馏或升华等方法被分离为个别非对映异构体。对映异构体可以通过分离,使手性异构混合物转化为非对映异构混合物,其方式是与适当光学活性化合物(例如手性辅助剂,譬如手性醇或Mosher氏酰氯)的反应,分离非对映异构体,且使个别非对映异构体转化为相应的纯对映异构体。本发明的中间体与化合物也可以不同互变异构形式存在,且所有此种形式被包含在本发明的范围内。很多有机化合物都以光学活性形式存在,即它们有能力旋转平面偏振光的平面。在描述光学活性化合物时,前缀D、L或R、S用来表示分子手性中心的绝对构型。前缀d、l或(+)、(-)用来命名化合物平面偏振光旋转的符号,(-)或l是指化合物是左旋的,前缀(+)或d是指化合物是右旋的。这些立体异构体的原子或原子团互相连接次序相同,但是它们的立体结构不一样。特定的立体异构体可以是对映体,异构体的混合物通常称为对映异构体混合物。50:50的对映体混合物被称为外消旋混合物或外消旋体,这可能导致化学反应过程中没有立体选择性或立体定向性。术语“外消旋混合物”和“外消旋体”是指等摩尔的两个对映异构体的混合物,缺乏光学活性。
“互变异构体”或“互变异构的形式”是指不同能量的结构的同分异构体可以通过低能垒互相转化。例如质子互变异构体(即质子移变的互变异构体)包括通过质子迁移的互变,如酮式-烯醇式和亚胺-烯胺的同分异构化作用。原子价(化合价)互变异构体包括重组成键电子的互变。除非其他方面表明,本发明所描述的结构式包括所有的同分异构形式(如对映异构,非对映异构,和几何异构):例如含有不对称中心的R、S构型,双键的(Z)、(E)异构体,和(Z)、(E)的构象异构体。因此,本发明的化合物的单个立体化学异构体或其对映异构体,非对映异构体,或几何异构体的混合物都属于本发明的范围。
“药学上可接受的盐”指本发明化合物的盐,这类盐用于人或动物体内时具有安全性和有效性。化合物的盐可以通过在纯的溶液或合适的惰性溶解中用足量的碱或酸获得相应的加成盐。可药用的碱加成盐包括钠、钾、钙、铵、有机氨或镁盐等,可药用的酸加成盐包括无机酸盐和有机酸盐,所述的无机酸和有机酸包括盐酸、氢溴酸、碳酸、碳酸氢根、磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸一氢根、乙酸、马来酸、丙二酸、琥珀酸、饭丁烯二酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸和甲磺酸等(参见Berge et al.,“PharmaceuticalSalts”,Journal of Pharmaceutical Science 66:1-19(1977))。
本文中可使用实线(-)、实楔形或虚楔形描绘本发明的化合物的化学键。使用实线以描绘键连至不对称碳原子的键欲表明,包括该碳原子处的所有可能的立体异构体(例如,特定的对映异构体、外消旋混合物等)。使用实或虚楔形以描绘键连至不对称碳原子的键欲表明,存在所示的立体异构体。当存在于外消旋混合物中时,使用实及虚楔形以定义相对立体化学,而非绝对立体化学。除非另外指明,否则本发明的化合物意欲可以立体异构体(其包括顺式及反式异构体、光学异构体(例如R及S对映异构体)、非对映异构体、几何异构体、旋转异构体、构象异构体、阻转异构体及其混合物)的形式存在。本发明的化合物可表现一种以上类型的异构现象,且由其混合物(例如外消旋混合物及非对映异构体对)组成。
本发明涵盖本发明的化合物的所有可能的结晶形式或多晶型物,其可为单一多晶型物或多于一种多晶型物的任意比例的混合物。
还应当理解,本发明的某些化合物可以游离形式存在用于治疗,或适当时,以其药学上可接受的衍生物形式存在。在本发明中,药学上可接受的衍生物包括但不限于,药学上可接受的盐、酯、溶剂合物、N-氧化物、代谢物、螯合物、络合物、包合物或前药,在将它们向需要其的患者给药后,能够直接或间接提供本发明的化合物或其代谢物或残余物。因此,当在本文中提及“本发明的化合物”时,也意在涵盖化合物的上述各种衍生物形式。
本发明的化合物的药学上可接受的盐包括其酸加成盐及碱加成盐,包括但不限于含有氢键或配位键的盐。
适合的酸加成盐由形成药学可接受盐的酸来形成。实例包括乙酸盐、己二酸盐、天冬氨酸盐、苯甲酸盐、苯磺酸盐、碳酸氢盐/碳酸盐、硫酸氢盐/硫酸盐、硼酸盐、樟脑磺酸盐、柠檬酸盐、环己氨磺酸盐、乙二磺酸盐、乙磺酸盐、甲酸盐、延胡索酸盐、葡庚糖酸盐、葡糖酸盐、葡糖醛酸盐、六氟磷酸盐、海苯酸盐、盐酸盐/氯化物、氢溴酸盐/溴化物、氢碘酸盐/碘化物、羟乙基磺酸盐、乳酸盐、苹果酸盐、顺丁烯二酸盐、丙二酸盐、甲磺酸盐、甲基硫酸盐、萘甲酸盐(naphthylate)、2-萘磺酸盐、烟酸盐、硝酸盐、乳清酸盐、草酸盐、棕榈酸盐、双羟萘酸盐、磷酸盐/磷酸氢盐/磷酸二氢盐、焦谷氨酸盐、糖二酸盐、硬脂酸盐、丁二酸盐、单宁酸盐、酒石酸盐、甲苯磺酸盐、三氟乙酸盐及昔萘酸盐(xinofoate)。

如本文中所使用,术语“酯”意指衍生自本申请中各个通式化合物的酯,其包括生理上可水解的酯(可在生理条件下水解以释放游离酸或醇形式的本发明的化合物)。本发明的化合物本身也可以是酯。
本发明的化合物可以溶剂合物(优选水合物)的形式存在,其中本发明的化合物包含作为所述化合物晶格的结构要素的极性溶剂,特别是例如水、甲醇或乙醇。极性溶剂特别是水的量可以化学计量比或非化学计量比存在。
本领域技术人员会理解,由于氮需要可用的孤对电子来氧化成氧化物,因此并非所有的含氮杂环都能够形成N-氧化物;本领域技术人员会识别能够形成N-氧化物的含氮杂环。本领域技术人员还会认识到叔胺能够形成N-氧化物。用于制备杂环和叔胺的N-氧化物的合成方法是本领域技术人员熟知的,包括用过氧酸如过氧乙酸和间氯过氧苯甲酸(MCPBA)、过氧化氢、烷基过氧化氢如叔丁基过氧化氢、过硼酸钠和双环氧乙烷(dioxirane)如二甲基双环氧乙烷来氧化杂环和叔胺。这些用于制备N-氧化物的方法已在文献中得到广泛描述和综述,参见例如:T.L.Gilchrist,Comprehensive Organic Synthesis,vol.7,pp748-750;A.R.Katritzky和A.J.Boulton,Eds.,Academic Press;以及G.W.H.Cheeseman和E.S.G.Werstiuk,Advances in Heterocyclic Chemistry,vol.22,pp 390-392,A.R.Katritzky和A.J.Boulton,Eds.,Academic Press。
在本发明的范围内还包括本发明的化合物的代谢物,即在给药本发明的化合物时体内形成的物质。这样的产物可由例如被给药的化合物的氧化、还原、水解、酰胺化、脱酰胺化、酯化、酶解等产生。因此,本发明包括本发明的化合物的代谢物,包括通过使本发明的化合物与哺乳动物接触足以产生其代谢产物的时间的方法制得的化合物。
本发明在其范围内进一步包括本发明的化合物的前药,其为自身可具有较小药理学活性或无药理学活性的本发明的化合物的某些衍生物当被给药至身体中或其上时可通过例如水解裂解转化成具有期望活性的本发明的化合物。通常这样的前药会是所述化合物的官能团衍生物,其易于在体内转化成期望的治疗活性化合物。关于前药的使用的其他信息可参见“Pro-drugs as Novel Delivery Systems”,第14卷,ACS Symposium Series(T.Higuchi及V.Stella)。本发明的前药可例如通过用本领域技术人员已知作为“前-部分(pro-moiety)(例如“Design of Prodrugs”,H.Bundgaard(Elsevier,1985)中所述)”的某些部分替代本发明的化合物中存在的适当官能团来制备。
本发明还涵盖含有保护基的本发明的化合物。在制备本发明的化合物的任何过程中,保护在任何有关分子上的敏感基团或反应基团可能是必需的和/或期望的,由此形成本发明的化合物的化学保护的形式。这可以通过常规的保护基实现,例如,在T.W.Greene&P.G.M.Wuts,Protective Groups in Organic Synthesis,JohnWiley&Sons,1991中所述的那些保护基,这些参考文献通过援引加入本文。使用本领域已知的方法,在适当的后续阶段可以移除保护基。

药理实验部分
测试例1KCNQ2的活性测试
1.质粒制备
人源电压门控钾离子通道KCNQ2(NP_004509.2)的基因被克隆到pIRES2-EGFP表达载体上,在CHO-K1细胞中进行异源表达。
2.细胞培养和转染
CHO-K1细胞(购自中国科学院细胞库)培养采用DMEM/F12培养液,并加入10%胎牛血清,放入二氧化碳恒温培养箱进行培养(5% CO2 37℃)。细胞传代时采用25%胰酶消化,待细胞密度达80%~100%时,参照Lipofectamine 300实验操作说明书进行转染质粒:A管加入OPTI-MEM 125μL,lip3000 5μL;B管加入OPTI-MEM 125μL,质粒2.5μg,P3000 5μL,将A管和B管混合,静置15min后,滴加至6孔板中,转染24h后将细胞用胰酶消化,离心后用细胞外液重悬滴加至培养皿中,选择带有绿色荧光标记的细胞进行电生理测试。
3.全细胞膜片钳实验
全细胞电生理实验记录在室温23~25℃条件下进行,采用HEKA EPC10膜片钳放大器,滤波为1kHz,采样频率为10kHz。膜片钳电极由水平电极拉制仪P-97经多步程序拉制完成,电阻为3~5MΩ。用于细胞记录的细胞外液为145mM NaCl、5mM KCl、1mM CaCl2、3mMMgCl2、10mM HEPES(pH 7.4,用NaOH调节),细胞内液为150mM KCl、3mM MgCl2、5mM EGTA、10mM HEPES(pH 7.3,用KOH调节)。封接破膜后,先将电压钳制在-80mV,再采用Step记录模式,给予-90mV到+60mV(每隔10mV递增,每2s一个sweep)的一系列去极化电压引出外向电流,然后给予-120mV超级化电压引出尾电流并记录。然后启用Ramp记录模式,在-10mV电压下先给细胞外液进行记录,当通道电流稳定后给予化合物(本发明三唑类衍生物,作为钾离子通道调节剂)。给药时间至少3min,最后当药物作用稳定后,用细胞外液洗回。快速给药系统为RSC-200,速度约为0.2mL/min。
4.数据分析和统计
采用Clampfit 10.4、GraphPad Prism 8.0.2等软件进行数据分析和作图。具体统计方法如下:
(1)药物效应统计。通过记录-10mV下测试给药前后的稳定外向电流来判断药物的效应。给药前的稳定电流平均值记为Icontrol,给药后稳定电流平均值记为I。药物对通道作用效应表示为I/Icontrol。
(2)药物的剂量效应曲线拟合。用公式E=Emax/(1+(EC50/C)P进行拟合,其中EC50是产生最大反应一半的药物浓度,P是Hill系数,C为药物浓度。
(3)电导-电压曲线(G-V curve)统计。通过记录一组去极化电压(-90mV至+60mV,每隔10mV递增)瞬间超极化到-120mV所激发的尾电流,来统计通道本身电压敏感性或者测试药物对通道电压敏感性的影响。以计算得到的最大电导Gmax作为标准进行归一化来统计每个电压下的G/Gmax。使用玻尔兹曼方程:G=Gmin+(Gmax-Gmin)/(1+exp(V-V1/2)/S)进行拟合,Gmax为最大电导,Gmin为最小电导,V1/2为达到最大电导50%时的电压,S为斜率因子。
采用配对t检验(Student’s paired t test)对数据进行统计分析,所有实验数据均以平均值±标准误(mean±S.E.M.)表示,P<0.05时认为两组之间的差异具有统计学意义。
试验结果见表4。
