Abstract
本发明涉及新的吡啶衍生物,含有他们的药物组合物,及其在治疗涉及离子通道例如钾通道的病症中的应用。
Description
发明领域
本发明涉及新的吡啶和喹啉衍生物,含有他们的药物组合物,及其在治疗涉及离子通道例如钾通道的病症中的应用。本发明化合物可用于治疗各种病症,包括但不限于尿失禁、膀胱活动过度、高血压、勃起机能障碍、良性前列腺增生、女性性障碍、早产、痛经、肠易激综合征、气道活动过强、癫痫、中风、缺血、阿尔茨海默氏病、帕金森病、心肌损伤、冠状动脉疾病、心绞痛、疼痛、饮食障碍、毛发损失、脱发和秃发。
发明背景
离子通道通过调节离子的跨膜运动而在细胞功能的稳态中起基本作用。细胞活动可以通过改变离子通道活性来影响。这导致膜电位差的改变。钾通道是一组不同并且普遍存在的离子通道。他们主要调节细胞的休止膜电位以及减弱细胞的兴奋水平。功能KATP通道是一种异八聚体,是由四个向内的精制钾通道亚单位受体(Kir6.2)和四个磺酰脲受体(SUR)亚单位装配成的。有两个SUR基因,SUR1和SUR2。SUR1/Kir6.2通道是在胰腺和脑中发现的。由SUR2基因产生两个主要的剪接变体,SUR2A和SUR2B,二者仅在C-末端42个氨基酸上有所不同。在心脏和骨骼组织中发现了SUR2A/Kir6.2通道,而在很多组织,包括膀胱的平滑肌中发现了SUR2B/Kir6.2通道(Aguilar-Bryan,L.;Clement J.P.;Gonzales,G.等人.(1998)“Toward understandingthe assembly and structure of KATP channels”Physiol.Rev.8:227-245)。有多种疾病或病症可以用钾通道打开剂来治疗。这些疾病或病症包括膀胱活动过度、尿失禁、男性勃起机能障碍、女性性障碍、早产、良性前列腺增生(BPH)、痛经、神经变性、中风、疼痛、冠状动脉疾病、心绞痛、缺血、饮食障碍、肠易激综合征和脱发。
尿失禁(UI)是一种可能影响患者整个生命质量的疾病。膀胱活动过度(OAB)是最流行的UI形式,据报道,在所有诊断出的UI病例中,流行率从40%提高到70%(Wein,A.J.(2000)“Overactive bladder:defining the disease”Am.J.Manag.Care.6:S559-564)。OAB的特征在于以下症状:尿频率增加、尿急和无意识排尿。OAB的主要原因是突然以及无意识收缩的过度敏感的膀胱。理想的药物活性剂应当抑制无意识的收缩,同时保持正常的排尿收缩完整。ATP-敏感性钾通道打开剂(KCO)能够起这样的活性剂的作用。ATP-敏感性钾通道(KATP)在膀胱平滑肌中表达,并且作为这些细胞中休止膜电位的关键调节剂而起作用。选择性地打开这些通道的化合物超极化细胞,并且降低细胞兴奋性,导致无意识膀胱收缩被抑制,同时保持正常排尿循环正常。

本发明化合物也可通过使用作为化合物分子与其偶联的单个载体的单克隆抗体传递。本发明化合物也可与作为靶向药物载体的可溶性聚合物偶联。这样的聚合物可包括聚乙烯吡咯烷酮、吡喃共聚物、聚羟基丙基甲基丙烯酰胺苯酚、聚羟基-乙基天冬酰胺苯酚或用棕榈酰残基取代的聚环氧乙烷聚赖氨酸。另外,本发明化合物可偶联于一类用于达到药物控制释放的可生物降解聚合物例如聚乳酸、聚ε-羟基己内酯、聚羟基丁酸(butyeric acid)、聚原酸酯、聚缩醛、聚二氢吡喃、聚氰基丙烯酸酯和水凝胶的交联或两性嵌段共聚物。
本发明化合物可以任何上述组合物并按照在需要治疗涉及离子通道,优选涉及钾离子通道的病症时所建立的剂量方案给药。
前药的每天剂量可在0.01-1000mg每成人每天的宽范围内变化。对于口服给药,组合物优选地以包含0.01、0.05、0.1、0.5、1.0、2.5、5.0、10.0、15.0、25.0、50.0、100、150、200、250和500毫克活性组分的片剂形式提供用于对所治疗的患者对症调节剂量。有效量的药物通常以约0.01mg/kg-约300mg/kg体重每天的剂量水平提供。优选地,范围为约0.05-约5.0mg/kg体重每天,最优选地为约0.05-约3.0mg/kg体重每天。化合物可以每天1-4次的方案给药。
所给予的最佳剂量可由本领域技术人员容易地确定并且将根据所使用的具体化合物、给药模式、制剂规格、给药方式及病症状况的发展而变化。另外,与所治疗的具体患者有关的因素包括患者年龄、体重、饮食和给药时间将导致需要调整剂量。
阐述以下实施例以助于理解本发明并且不打算和不应该以任何方式构成对在随后的权利要求中阐述的本发明的限制。
在随后的实施例中,一些合成产物可作为已经被分离为残余物得到列举。本领域普通技术人员应该理解术语“残余物”不限制其中产物被分离的物理状态,并且可包括例如固体、油状物、泡沫状物、胶状物、浆状物等。
