Description
技术领域
本发明属于化学医药领域,具体涉及一种用于制备钠和/或钙通道调节剂的烟酰胺衍生物。
背景技术
离子通道是细胞膜上特异性转运离子的通道,往往是由数个跨膜蛋白亚单位构成。离子通道在神经系统的信息传递、心脏的节律性跳动、激素的分泌、肌肉的收缩等生理活动中起重要作用。根据转运的离子种类,可以将其分为钠离子通道、钙离子通道、钾离子通道等。
钠离子通道是一种电压门控的跨膜离子通道,广泛存在于可兴奋的细胞中。钠离子通道的开放使钠离子顺着电化学梯度进入细胞,细胞去极化并传播动作电位,因此钠离子通道在维持细胞的兴奋性与细胞信号的传导中起重要作用。基于对河豚毒素的敏感性来进行分类,目前已知的钠离子通道一共有9种亚型,分别为Navl.1—Nav1.9。基于钠离子通道的重要生理功能,目前已有多种作用于钠通道的药物成功上市,包括:局部麻醉剂、Ⅰa类抗心律失常剂、抗惊厥剂、抗癫痫药(苯妥英和卡马西平对三叉神经痛、舌咽神经痛非常有效)、双相性精神障碍(拉莫三嗪)等。另外,在若干炎性疼痛模型中已经观察到钠通道表达或活性的增加,提示了钠通道在炎性疼痛中的角色。
钙离子通道是一种选择性通过钙离子的跨膜离子通道,这些通道可以通过电压或配体结合进行门控。电压门控性钙通道的开关是由膜电位控制的,哺乳动物“可兴奋的“细胞,例如中枢神经系统(CNS)的神经元、外周神经细胞和肌肉细胞、包括骨骼肌、心肌和静脉与动脉平滑肌,都具有电压依赖性钙通道。电压门控性钙通道根据钙通道传导性和对电压敏感性的不同,又进一步分为L-型、P/Q-型、T-型、N-型、R-型。电压门控性钙通道的调节与细胞许多生命活动密切相关,例如神经递质释放,肌肉收缩,起搏点活动和激素分泌,因此钙离子通道也成为了重要的药物靶点。钙通道阻滞药在临床上多用于治疗心脏和血管系统疾病,如心律失常、高血压、心肌缺血性疾病(冠心病、心绞痛)、脑血管疾病、慢性心功能不全等,代表药物有维拉帕米、硝苯地平,氨氯地平、非洛地平、地尔硫等。
具有钙通道活性的化合物也已被推断用于治疗疼痛。特别是负责神经递质释放调节的N-型钙通道,被认为在疼痛的传递中扮演重要角色,这不仅由于它们的组织分布,也来自若干药理学研究的结果。在损伤的神经病性疼痛模型中发现N-型钙通道在同侧背侧角中被增量调节了(Cizkova D.,Marsala J.,Lukacova N.,Marsala M.,Jergova S.,Orendacova J.,Yaksh T.L.Exp.Brain Res.(2002)147:456-463)Specific N-typecalcium channel blockers were shown to be effective in reducing painresponses in neuropathic pain models(Mattews E.A.,Dickenson A.H.Pain(2001)92:235-246)Ⅱ期福尔马林试验(D iazA.,Dickens on A.H.Pain(1997)69:93-100)和由膝关节炎症诱发的痛觉过敏(Nebe J.,Vanegas H.,Schaible H.G.Exp.Brain Res.(1998)120:61-69)中显示钙通道阻滞剂可有效降低疼痛反应。缺N-型钙通道的突变小鼠被发现对持续性疼痛敏感性降低,表现为Ⅱ期福尔马林试验期间的疼痛反应降低(KimC.,JunK.,LeeT.,KimS.S.,Mcenery M.W.,Chin H.,Kim H.L,Park J.M.,Kim D.K.,Jung S.J.,Kim J.,ShinH.S.Mol.Cel 1Neurosci.(2001)18:235-245;Hatakeyama S.,Wakamori M,Ino M.,Miyamoto N.,Takahashi B.,Yoshinaga T.,Sawada K.,Imoto K.,Tanaka I.,YoshizawaT.,Nishizawa Y.,Mori Y.,Nidome T.,Shoji S.Neuroreport(2001)12:2423-2427),以及降低了神经病性疼痛反应,表现为脊神经结扎模型中的机械性异常疼痛和热性痛觉过敏降低。有趣的是,这些小鼠也显示比野生型更低的焦虑水平(Saegusa H.,Kurihara T.,ZongS.,Kazuno A.,Matsuda Y.Nonaka T.,Han W.,Toriyama H.,Tanabe T.,BMBO J.(2001)20:2349-2356)N-型钙通道在疼痛中的牵连性。已经在临床上得到齐考诺肽的进一步验证,这是一种从海洋小螺Conus Magnus毒液衍生的肽。这种肽在治疗应用上的限制在于它只能对人类鞘内进行给药(Bowers ox S.S.Luther R.Toxicon,(1998)36:1651-1658)
所有这些发现都表明,具有钠和/或钙通道阻断作用的化合物在预防、减轻和治愈广泛的病状中具有很高的治疗潜力,包括神经病学的、精神病学的、泌尿生殖和胃肠疾病。
有很多文章和专利描述过治疗或调节多种障碍的钠通道和/或钙通道调节剂或阻滞剂,例如它们用作局部麻醉剂、抗躁狂抗抑郁剂、治疗单极性抑郁、尿失禁、腹泻、炎症、癫痫、神经变性病症、神经细胞死亡、神经病性疼痛、偏头痛、急性痛觉过敏与炎症、肾疾病、变态反应、哮喘、支气管痉挛、痛经、食管痉挛、青光眼、尿道障碍、胃肠运动障碍的药物。这类描述钠和/或钙通道阻断剂及其应用的文章和专利/专利申请的不完全列表包括如下所示的参考文献:

实施例7:钙通道流入测定法
AtT20细胞在含有10%PBS、4mM谷氨酰胺的DMEM中培养。将细胞按2*105细胞/孔的密度接种在涂布聚-L-赖氨酸的96孔中,培养18-24h备用。
使用Ca2+ Kit Assay(Molecular Devices)进行测定,将细胞与钙染料在37℃下孵育30分钟,然后单独加入或者在尼非地平(作为参照标准)或不同浓度待测药物存在下加入ω-芋螺毒素(1μM),进一步孵育15分钟。在100mM KCl去极化溶液的自动注射之前和之后(30-40s),测量荧光(激发波长:485nm,发射波长:535nm)。
共进行3次平行实验,实验结果取平均值。实验结果如表3所示,实施例1-5与对照相ralfinamide、safinamide比均表现出较强的钙通道抑制活性,实施例1-5表现出与NW-3509相当的抑制活性。

实施例8:使用人体肝脏微粒体进行化合物稳定性的评价
将实施例化合物的肝微粒体酶稳定性与NW-3509进行比较。
步骤如下:将待测药物与人肝药酶、NADPH在37℃下孵育30min,并于0、1、3、5、7、9、11、13、15、20、22、30分钟取样,样品用冰乙腈终止反应,在4℃下离心,利用LC-MS/MS检测上清液中底物剩余量。结果见表4。
表4:各化合物清除率结果

实施例1 | 8 |
实施例2 | 10 |
实施例3 | 9 |
实施例4 | 11 |
实施例5 | 12 |
NW-3509 | 15 |
由表4可见,实施例1-5均表现为较低的清除率,优于NW-3509,优良的代谢稳定性使得它们具有降低医疗剂量和扩大给药时间间隔的潜能。
由实施例1-5的化合物具体钠离子内流IC50值、钙离子内流IC50值、及代谢清除率可知,对于通式(I)的化合物而言,连接基团和取代基团比如R1、R2、R3和R4基团对于化合物的药效学性能和代谢稳定性有着重要的影响。
以上所提供的实施例并非用以限制本发明所涵盖的范围,所描述的步骤也不是用以限制其执行顺序。本领域技术人员结合现有公知常识对本发明做显而易见的改进,亦落入本发明权利要求书所界定的保护范围之内。
