Description
相关申请的交叉引用
本申请要求Runyon等人于2015年12月9日提交的题为“Improved ApelinReceptor(APJ)Agonists and Uses Thereof”的美国临时申请62/265,168和Runyon等人于2015年12月9日提交的题为“Difluoro Apelin Receptor(APJ)Agonists and UsesThereof”的美国临时申请62/265,177的权益,这些临时申请据此通过引用以其整体并入。
1.领域
本公开内容总体上涉及爱帕琳肽受体(apelin receptor)(APJ)的激动剂和这样的激动剂的用途的发现。
2.背景
2.1.引言:爱帕琳肽和爱帕琳肽受体(APJ)
爱帕琳肽受体(APJ)在1993年作为孤儿G蛋白偶联受体(orphan G-proteincoupled receptor)(GPCR)被克隆。人类APJ基因位于染色体11的长臂上并且编码377个氨基酸的G蛋白偶联受体。由于两个受体之间的序列相似性,用于APJ的基因被定名为血管紧张素受体样1(angiotensin-receptor like 1)(AGTRL1)。Carpene等人,J PhysiolBiochem.2007;63(4):359–373。然而,用于血管紧张素受体的已知的肽能配体(peptidergic ligand)(包括血管紧张素)中没有一个激活APJ。APJ仍然是孤儿GPCR直到1998年,此时肽爱帕琳肽被识别为其内源性配体。Lee等人,J Neurochem.2000;74(1):34–41;Habata等人,Biochim Biophys Acta.1999;1452(1):25-35。
多年来,爱帕琳肽和APJ已经显现为多种生理过程的重要调节者。爱帕琳肽和APJ两者均在中枢神经系统(CNS)中表达,并且在许多组织中外周地表达。APJ的表达已经在某些器官的脉管系统中被注意到,并且是相关过程的强有力的调节者,该相关过程包括血管生成和血管收缩。Cobellis等人报道了在先兆子痫并发的妊娠(preeclampsia-complicated pregnancy)中的爱帕琳肽和APJ受体两者的表达水平的增加。Cobellis等人,Histol Histopathol.2007;22(1):1-8。APJ还在心脏、肝脏和CNS的非血管细胞类型中表达,其中APJ的主要作用目前正在研究中。Medhurst等人,J Neurochem.2003;84(5):1162-1172。爱帕琳肽和APJ经常被共同定位在同一器官中,这表明受体通过其配体自分泌调节。然而,爱帕琳肽已经在血液中被检测到,这表明受体的伴随的旁分泌调节也是可能的。爱帕琳肽-APJ系统已经被暗示为多种生理功能的调节者,并且被认为在体温调节、免疫、葡萄糖代谢、血管生成、体液平衡(fluid homeostasis)、心脏功能、肝功能和肾功能中起重要作用。Ladeiras-Lopes等人,Arq Bras Cardiol.2008;90(5):343-349。APJ还在HIV感染期间充当共受体(co-receptor)。O’Donnell等人,J Neurochem.2007;102(6):1905–1917;Zou等人,FEBS Lett.2000;473(1):15-18。
爱帕琳肽和APJ的表达在多种病理生理状况中被上调或下调。特别地,APJ表现为是用于治疗心血管衰竭(cardiovascular failure)、肝纤维化、癌症、血管病(angiopathy)、胰腺炎以及作为预防HIV感染的新兴靶。在2011年,Andersen等人考察了爱帕琳肽和APJ作为用于肺高血压和肺动脉高血压(PAH)的治疗用途的机会。Andersen等人,Pulm.Circ.2011;1(3)334-346。
不幸的是,缺乏APJ的具有合适的药理学性质的小分子配体。迄今为止,很少的非肽配体系统被报道。Iturrioz等人报道了包含多环荧光团的化合物,例如丽丝胺(lissamine),这使得它们不适合于药物用途。Iturrioz等人,FASEB J.2010;24:1506-1517;EP 1903052(Llorens-Cortes等人)。美国公布专利申请2014/0094450(Hachtel等人)公开了苯并咪唑-羧酸酰胺衍生物作为APJ受体调节剂。
因此,存在对于APJ的小分子激动剂的需求。

在一个非限制性实施方案中,本公开内容提供了治疗受试者中的爱帕琳肽受体(APJ)相关的紊乱的方法,所述方法包括向受试者施用实施方案1的化合物。爱帕琳肽受体(APJ)相关的紊乱可以是哮喘、动脉粥样硬化、癌症、心肌病、糖尿病、血脂异常、高血压、炎症、肝病、代谢紊乱、神经退行性疾病、肥胖症或先兆子痫。本公开内容提供了方法,所述方法还包括用α-阻断剂、血管紧张素转化酶(ACE)抑制剂、血管紧张素受体阻断剂(ARB)、β-阻断剂、钙通道阻断剂或利尿剂治疗受试者。可选择地,本公开内容提供了治疗或预防静脉相关的紊乱例如血管瘤、静脉功能不全、瘀或血栓形成的方法。
此外,本公开内容提供了预防受试者中的HIV神经变性的方法,所述方法包括向受试者施用实施方案1的化合物。
在一个实施方案中,本公开内容的化合物的有效量可以在从每次治疗约0.005mg至约5000mg的范围内。在更特定的实施方案中,该范围是从约0.05mg至约1000mg、或者从约0.5mg至约500mg、或者从约5mg至约50mg。治疗每天可以被施用一次或更多次(例如,每天一次、每天两次、每天三次、每天四次、每天五次等)。当使用多次治疗时,量可以相同或不同。应当理解,治疗可以被每天、每隔一天、每2天、每3天、每4天、每5天等施用。例如,在每隔一天施用的情况下,治疗剂量可以在星期一开始,并且第一随后治疗在星期三施用,第二随后治疗在星期五施用等。治疗典型地被从每日一次至每日两次施用。如本领域技术人员认识到的,取决于治疗的疾病、疾病的严重程度、施用途径、受试者的性别、年龄和一般健康状况、赋形剂用法、与其他治疗性治疗共使用(co-usage)的可能性例如使用其他剂、以及治疗医师的判断,有效剂量也将变化。
可选择地,本公开内容的化合物的有效量是从约0.01mg/kg/天至约1000mg/kg/天、从约0.1mg/kg/天至约100mg/kg/天、从约0.5mg/kg/天至约50mg/kg/天、或从约1mg/kg/天至10mg/kg/天。
在另一个实施方案中,上文治疗方法中的任何包括向所述受试者共施用(co-administer)一种或更多种第二治疗剂的另外的步骤。第二治疗剂的选择可以从已知可用于与调节APJ受体的化合物共施用的任何第二治疗剂中进行。第二种治疗剂的选择还取决于待被治疗的特别的疾病或状况。可以在本公开内容的方法中使用的第二治疗剂的实例是上文所陈述的用于在包含本公开内容的化合物和第二治疗剂的组合组合物中使用的第二治疗剂。
如本文使用的术语“共施用”意指第二治疗剂可以连同本公开内容的化合物作为单个剂型的一部分(例如包含本公开内容的化合物和如上文描述的第二治疗剂的本公开内容的组合物)或作为单独的多剂型来施用。可选择地,另外的剂可以在施用本公开内容的化合物之前、与本公开内容的化合物的施用连续地或在施用本公开内容的化合物之后被施用。在这样的组合疗法治疗中,本公开内容的化合物和第二治疗剂两者均通过常规方法来施用。向受试者施用包含本公开内容的化合物和第二治疗剂两者的本公开内容的组合物不排除在治疗过程期间的另一时间,将该相同的治疗剂、任何其他第二治疗剂或本公开内容的任何化合物单独施用至所述受试者。
在本公开内容的一个实施方案中,在第二治疗剂被施用至受试者的情况下,本公开内容的化合物的有效量小于其在不施用第二治疗剂的情况下的有效量。在另一个实施方案中,第二治疗剂的有效量小于其在不施用本公开内容的化合物的情况下的有效量。以这种方式,与任一剂的高剂量有关的不期望的副作用可以被最小化。其他潜在的优点(包括而不限于改进的给药方案和/或降低的药物成本)对于本领域技术人员将是明显的。

本公开内容的药盒还可以包括施用或测量药物组合物的单位剂量的装置。如果所述组合物是可吸入组合物,那么这样的装置可以包括吸入器;如果所述组合物是可注射组合物,那么这样的装置可以包括注射器和针头;如果所述组合物是口服液体组合物,那么这样的装置可以包括具有或不具有体积标记的注射器、匙、泵或器皿;或者这样的装置可以包括适于药盒中存在的组合物的剂量制剂(dosage formulation)的任何其他测量或递送装置。
在某些实施方案中,本公开内容的药盒可以在容器的单独器皿中包含药物组合物,所述药物组合物包含第二治疗剂,例如上文列出的用于与本公开内容的化合物共施用的第二治疗剂中的一种。
除非另外定义,否则本文使用的所有技术术语和科学术语具有与本公开内容所属领域的普通技术人员通常理解的相同的含义。冠词“一(a)”和“一个(an)”在本文中用于指的是一个或多于一个(即至少一个)该冠词的语法对象(grammatical object)。通过实例的方式,“要素(an element)”意指一个或更多个要素。
在整个本说明书中,词语“包括(comprising)”或变型例如“包括(comprises)”和“包括(comprising)”,将被理解为意味着包括所陈述的要素、整数或步骤,或者要素、整数或步骤的组但不排除任何其他的要素、整数或步骤,或者要素、整数或步骤的组。本公开内容可以合适地“包括”权利要求中描述的步骤、要素和/或试剂、“由权利要求中描述的步骤、要素和/或试剂组成”或者“基本上由权利要求中描述的步骤、要素和/或试剂组成”。
还应注意,权利要求可以被起草为排除任何任选的要素。因此,此陈述意图用作用于与权利要求要素的叙述相关的这样的排他的术语如“唯一地(solely)”、“仅(only)”及类似术语的使用或“否定”限制的使用的前置基础。
在提供值的范围的情况下,应当理解,除非上下文另外明确指明,否则在该范围的上限和下限之间的每一个中间值至下限单位的十分之一也被具体地公开。在所陈述的范围内的任何陈述的值或中间值和在该陈述的范围内的任何其他陈述的值或中间值之间的每个较小的范围被涵盖在本公开内容内。这些较小的范围的上限和下限可以独立地被包括在该范围内或排除在该范围之外,并且其中任一极限、两个极限都不或者两个极限都被包括在较小范围内的每个范围也被涵盖在本公开内容中,受限于陈述的范围内的任何特定排除的极限。在陈述的范围包括所述极限中的一个或两个的情况下,排除那些所包括的极限中的任一个或两个的范围也被包括在本公开内容中。
以下实施例进一步例证本公开内容,并且不意图限制本公开内容的范围。特别地,应当理解,本公开内容不限于所描述的特定实施方案,并且因此当然可以变化。还应当理解,本文使用的术语仅仅是用于描述特定实施方案的目的,并且不意图是限制性的,因为本公开内容的范围将仅由所附的权利要求来限制。
