Abstract
本发明涉及式(I)的化合物,Z-C(R1R2)-C(R3NH2)-C(R4R5)-X-N(R6R7)其中Z、R1-7和X具有说明书和权利要求中所述的含义。所述化合物可用作DPP-IV抑制剂。本发明还涉及这些化合物的制备,及其作为药物的生产和用途。
Description
本发明涉及一类新的二肽基肽酶抑制剂,包括其药物可接受的盐及前药,所述的抑制剂及其药物可接受的盐及前药特别是在通常称为非胰岛素依赖性糖尿病(NIDDM)的2型糖尿病和常与该疾病相关如肥胖和脂质失调病症的治疗中可用作治疗性化合物。
糖尿病是指这样的一种疾病过程,它源于多种致病因素,并以血浆葡萄糖水平升高、或者禁食状态或在口服葡萄糖耐量测试中给予葡萄糖后的高血糖为特征。持续的或未受控制的高血糖与增加的和过早的发病与死亡相关。通常异常的葡萄糖稳态直接和间接地与脂质、脂蛋白和载脂蛋白代谢改变以及其它代谢性和血流动力性疾病相关。因此患2型糖尿病患者的大血管和微血管并发症的危险性增高,这些并发症包括冠心病、中风、外周血管疾病、高血压、肾病、神经病和视网膜病。因此,葡萄糖稳态、脂质代谢和高血压的治疗性控制在对糖尿病的临床处理和治疗中非常重要。
糖尿病有两种公认的形式。在1型或胰岛素依赖性糖尿病(IDDM)中,患者产生极少的胰岛素——调节葡萄糖利用的激素——或不产生胰岛素。在2型或非胰岛素依赖性糖尿病(NIDDM)中,患者通常具有与非糖尿病受试者相同或较之升高的血浆胰岛素水平。这些患者对于胰岛素在胰岛素敏感的主要组织——即肌肉、肝和脂肪组织——中对葡萄糖和脂质代谢的刺激作用产生耐受。而且当血浆胰岛素水平升高,也不足以克服显著的胰岛素耐受性。
胰岛素耐受性并不主要是由于胰岛素受体数的减少,而是由于还不清楚的后胰岛素受体结合缺陷。这种对胰岛素应答的耐受导致肌肉中葡萄糖摄入、氧化和储存的胰岛素激活不足,以及脂肪组织中脂解和肝脏中葡萄糖产生和分泌的胰岛素抑制不足。
多年来没有显著改变的2型糖尿病的可用疗法具有公认的局限性。虽然体育锻炼和减少卡路里的饮食摄入将显著改善糖尿病病情,但由于长期确立的不活动的生活方式和过量的食物消耗,尤其是饱和脂肪含量高的食物,使得这种疗法的顺应性非常差。通过刺激胰β细胞以分泌更多胰岛素的磺酰脲类(如甲磺丁脲(tolbutamide)和格列甲嗪(glipizide))或氯茴苯酸(meglitinide)的给药,和/或当磺酰脲类或氯茴苯酸变为无效时通过注射胰岛素,来提高血浆胰岛素水平,可使得胰岛素浓度高至足以刺激对胰岛素耐受的组织。然而,胰岛素或胰岛素促分泌素(磺脲类或氯茴苯酸)的给药可导致危险的低血浆葡萄糖水平,并且由于更高的血浆胰岛素水平,可产生胰岛素耐受水平升高。双胍类增加胰岛素敏感性使得高血糖得到部分校正。然而,两种双胍类药物,苯乙双胍(phenformin)和二甲双胍(metformin),可导致乳酸性酸中毒和恶心/腹泻。二甲双胍比苯乙双胍副作用少,并且常将其开处方用于治疗2型糖尿病。
格列酮类(glitazones)(即5-苄基噻唑烷-2,4-二酮)是近来所述的一类具有改善2型糖尿病多种症状可能性的化合物。这些药物显著增加了一些2型糖尿病动物模型的肌肉、肝和脂肪组织中的胰岛素敏感性,使得升高的血浆葡萄糖水平得到部分或完全的校正而没有发生高血糖。现市售的格列酮类为过氧化物酶体增殖物激活性受体(PPAR)——主要是PPAR-γ亚型——激动剂。一般认为PPAR-γ的激动作用是采用格列酮类药物时观察到的胰岛素敏感性改善的原因。更新型的正在进行2型糖尿病治疗试验的PPAR-γ激动剂是α、γ或δ亚型的激动剂,或是它们的结合,并且此类激动剂在很多情况下在化学上不同于格列酮类(即它们不是噻唑烷类)。一些格列酮类药物已发生严重的副反应(如肝毒性),如曲格列酮(troglitazone)。
治疗该疾病的其它方法仍在研究中。近来提出或仍处于开发中的新的生物化学方法包括采用α-葡萄糖苷酶抑制剂(如阿卡波糖(acarbose))和蛋白酪氨酸磷酸酶-IB(PTP-IB)抑制剂的治疗。
二肽基肽酶-IV(DPP-IV)酶抑制剂化合物作为可用于糖尿病,尤其是2型糖尿病治疗的药物也处于研究中。参见例如,WO-A-97/40832,WO-A-98/19998,WO-A-03/180和WO-A-03/181。DPP-IV抑制剂在2型糖尿病治疗中的有效性基于以下事实,即DPP-IV在体内易使胰高血糖素样肽-1(GLP-1)和胃抑肽(gastric inhibitory peptide,GIP)失活。GLP-1和GIP为肠降血糖素,并且在食物消耗时产生。肠降血糖素刺激胰岛素产生。DPP-IV抑制导致肠降血糖素失活减少,这又转而使得肠降血糖素在刺激胰脏产生胰岛素中的有效性增加。因此DPP-IV抑制导致血清胰岛素水平增高。有利地,因为肠降血糖素仅当食物消耗时才由身体产生,所以预计DPP-IV抑制不会在可导致血糖过低(低血糖)的不当的时间——如两餐之间——增加胰岛素水平。因此预计DPP-IV抑制能够增加胰岛素水平,但不增加低血糖的危险性,而低血糖是与胰岛素促分泌素使用相关的危险副作用。
DPP-IV抑制剂可能还有如本申请其它部分所述的其它治疗用途。DPP-IV抑制剂目前还没有广泛研究,尤其是用于糖尿病以外的用途的研究。需要新的化合物,以便可寻找到用于糖尿病和可能的其它疾病和病症治疗的改良DPP-IV抑制剂。
因此,本发明的目的是提供一类可有效治疗2型糖尿病和其它DPP-IV调节疾病的新的DPP-IV抑制剂。

式(I)或(Ia)化合物的代谢物也在本发明的范围内。
当通式(I)或(Ia)化合物或者它们的前药可发生互变异构例如酮-烯醇互变异构时,要求对单独的形式,例如酮和烯醇形式,予以单独的保护或作为以任意比例的混合物一起保护。对于立体异构体,例如对映异构体、顺/反异构体、构象异构体等同样适用。如果需要,可以通过本领域公知的方法,例如液相色谱法分离异构体。通过使用例如手性固定相,同样适用于对映异构体。另外,也可以通过将对映异构体转变为非对映异构体来分离对映异构体,即与对映异构纯的辅助化合物偶联、随后分离得到的非对映异构体并将辅助残基解离。或者,式(I)或(Ia)化合物的任意对映异构体也可用光学纯的起始物通过立体选择性合成而获得。

DPP-IV相关疾病在WO-A-03/181的“用途(Utilities)”章节中作了更详尽的叙述,该内容通过引用的方式纳入本说明书。
因此本发明提供了用作药物的式(I)或(Ia)化合物或它们的前药或其药物可接受的盐。

组合物包括适于口服、直肠、局部、肠胃外(包括皮下、肌内和静脉内)、眼部(眼科)、肺部(鼻或口腔吸入)或鼻部给药的组合物,然而在任何给定情形下最合适的途径将取决于所治疗状况的性质和严重性和活性成分的性质。它们可方便地以单位剂型存在并且可通过药学领域公知的任何方法制备。
在实际使用中,式(I)或(Ia)化合物可根据常规的药物配合技术作为均匀混合物(intimate admixture)中的活性成分与药用载体混合。载体可依据给药——例如口服或肠胃外(包括静脉内)——所需的制剂形式有很多种形式。在制备口服剂型的组合物时,就口服液体制剂,例如悬浮剂、酏剂和溶液而言,可使用任何常用的药用介质,例如水、乙二醇、油类、醇类、调味剂、防腐剂、着色剂等等;或者就口服固体制剂,例如粉剂、硬胶囊和软胶囊以及片剂而言为载体,例如淀粉、糖、微晶、纤维素、稀释剂、粒化剂、润滑剂、粘合剂、崩解剂等等,其中固体口服制剂优选于液体制剂。
由于容易给药,片剂和胶囊成为最有利的口服单位剂型,在这种情形下,显然固体药用载体得到应用。若需要,可通过标准的水性或非水性技术进行片剂包衣。这种组合物和制剂应当含有至少0.1%的活性化合物。当然,这些化合物中的活性化合物百分比可改变,并且可方便地为单位重量的2%到60%之间。在此治疗有用的组合物中活性化合物的量为能够获得有效剂量。活性化合物还可鼻内给药,例如以液体滴剂或喷雾剂的形式。

适于注射使用的药用形式包括无菌水溶液或分散系、和用于临时制备无菌注射溶液或分散系的无菌粉末。在所有的情形中,该形式必须是无菌的,并且必须为达到具易于注射程度的液体。它在生产和贮存条件下必须是稳定的,并且必须经过了防腐处理以对抗微生物如细菌和真菌的污染作用。载体可以是含有例如水、乙醇、多元醇(如甘油、丙二醇和液体聚乙二醇)、它们的合适混合物和植物油的溶剂或分散介质。
任何合适的给药途径均可用于将有效剂量的本发明化合物提供给哺乳动物,尤其是人类。例如,可应用口服、直肠、局部、肠道外、眼部、肺部、鼻部等。剂型包括片剂、含片、分散系、悬浮液、溶液、胶囊、乳膏、软膏、气雾剂等等。优选口服给药式(I)或(Ia)化合物。
所用活性成分的有效剂量可依所用的特定化合物、给药方式、治疗状况和治疗状况的严重性而变化。该剂量可容易地由该领域技术人员确定。
当治疗或预防式(I)化合物所指出的糖尿病和/或高血糖或高甘油三酯血症或其它疾病时,给予日剂量为每千克动物体重约0.1毫克到约100毫克的本发明化合物,优选以每日单剂量或分为一天两到六次的剂量形式、或持续释放的形式给出,一般得到满意的结果。对于多数较大的哺乳动物,每日总剂量为约1.0毫克到约1000毫克,优选约1毫克到约50毫克。对于70kg的成人,每日总剂量一般为约7毫克到约350毫克。可对该剂量方案进行调整以提供最佳治疗应答。

用连续荧光分析监测对DPP-IV肽酶活性的抑制。该分析基于DPP-IV裂解底物Gly-Pro-AMC(Bachem),释放游离的AMC。分析在96孔微量滴定板中进行。在总体积100μL的情况下,化合物用50pMDPP-IV预温育,采用含10mM Hepes、150mM NaCl,0.005%吐温20的缓冲液(pH7.4)。通过加入16μM底物使反应开始,并在25℃下用荧光读数仪(BMG-Fluostar;BMG-Technologies)检测10min释放的AMC的荧光,激发波长为370nm,发射波长为450nm。DMSO终浓度为1%。测定化合物的抑制效能。用人和猪的DPP-IV进行DPP-IV活性分析(见下文);两种酶显示活性相当。
缺少穿膜锚(transmembrane anchor)(Gly31-Pro766)的可溶性人DPP-IV以Pre-Pro-α配对融合形式在重组YEAST株中表达。从发酵液(>90%纯度)中纯化得到分泌产物(rhuDPP-IV-Gly31-Pro766)。
表中列出在上述分析中测得的抑制DPP-IV肽酶活性的IC50值。将这些IC50值分为三组:a≤100nM;b≥101nM且≤1001nM;c≥1001nM≤2000nM。
