术语氨基保护基团被理解为适用于保护氨基酸残基侧链官能团的基团(例如参见T.W.Greene,P.G.M.Wuts《有机合成中的保护基团》第2版，John Wiley and Sons,New York 1991)。主要采用下列保护基团：叔丁氧基-羰基(BOC)、9-芴基甲氧基-羰基(Fmoc)、苄氧基-羰基(Z)、2-(3,5-二甲氧基苯基)丙-2-基氧基羰基(Ddz)、甲基、叔丁基、三苯甲基、S-叔丁基。
由于水溶性优于原始化合物或基本化合物，药学上可耐受的盐尤其适合于药用。这些盐必须具有药学上可耐受的阴离子或阳离子。根据本发明的化合物的适合的药学上可耐受的酸加成盐是无机酸的盐，酸例如盐酸、氢溴酸、磷酸、偏磷酸、硝酸、磺酸和硫酸，和有机酸的盐，酸例如乙酸、苯磺酸、苯甲酸、柠檬酸、乙磺酸、富马酸、葡糖酸、乙醇酸、羟乙磺酸、乳酸、乳糖酸、马来酸、苹果酸、甲磺酸、琥珀酸、对甲苯磺酸、酒石酸和三氟乙酸。出于药用目的，尤其优选地使用氯化物盐。适合的药学上可耐受的碱式盐是铵盐、碱金属盐(例如钠和钾盐)和碱土金属盐(例如镁和钙盐)。
与非药学上可耐受的阴离子所形成的盐同样包括在本发明范围内，因为它们是药学上可耐受的盐的制备或纯化的有用中间体，和/或用在非治疗应用、例如体外应用中的有用中间体。
这里所用的术语“生理学上的功能衍生物”指代根据本发明的式Ⅰ化合物的任意生理学上可耐受的衍生物，例如酯，它们一旦对哺乳动物、例如人给药后，能够(直接或间接)生成式Ⅰ化合物或其活性代谢产物。
生理学上的功能衍生物也包括根据本发明的化合物的前体药物。这类前体药物能够在体内代谢成为根据本发明的化合物。这些前体药物本身可以是活性或无活性的。
根据本发明的化合物也可以以各种多晶型形式存在，例如无定形和结晶的多晶型形式。根据本发明的化合物的全部多晶型形式都包括在本发明范围内，是本发明的进一步内容。
下文中，全部关于“根据式(Ⅰ)的化合物”的称谓都涉及如上所述的式(Ⅰ)化合物和如本文所述的它们的盐、溶剂化物和生理学上的功能衍生物。
为了达到所需生物学作用所必需的式(Ⅰ)化合物的量取决于一系列因素，例如所选择的具体化合物、所需用途、给药途径和患者的临床状况。一般来说，每日剂量为0.1mg至100mg(通常从0.1mg至50mg)每天每千克体重，例如0.1-10mg/kg/天。片剂或胶囊剂例如可以含有0.01至100mg，通常为0.02至50mg。在药学上可耐受的盐的情况下，上述重量涉及从该盐衍生的氨基丙醇离子的重量。式(Ⅰ)化合物本身可以以化合物的形式用于上述疾病的预防或治疗，但是它们优选地与可耐受的赋形剂一起以药物组合物的形式存在。当然，该赋形剂必须是可耐受的，也就是说它与组合物的其它组分是相容的，并且对患者无害。赋形剂可以是固体或液体，或二者皆是，优选地与化合物配制成单一剂量，例如可以含有0.05至95重量％活性物质的片剂。还可以存在其它药学上的活性物质，包括其它式(Ⅰ)化合物。根据本发明的药物组合物可以通过一种已知的药学方法加以制备，制备方法的本质在于将各组分与药理学上可耐受的赋形剂和/或助剂混合。
根据本发明的药物组合物是适合于口服和经口(例如舌下)给药的那些，不过在每种具体情况下，最适合的给药途径取决于所治疗疾病的性质与严重性和在每种情况下所用式(Ⅰ)化合物的性质。糖衣制剂和糖衣缓释制剂也属于本发明范围。耐酸和胃液制剂是优选的。适合的耐胃液包衣包括乙酸邻苯二甲酸纤维素、聚乙酸邻苯二甲酸乙烯酯、羟丙基甲基纤维素的邻苯二甲酸酯和异丁烯酸与异丁烯酸甲酯的阴离子聚合物。
适合于口服给药的药物化合物可以存在于独立的单元内，例如是胶囊剂、糯米纸囊剂、锭剂或片剂，它们均含有一定量的式(Ⅰ)化合物；例如是粉末或颗粒；例如是在水性或非水性流体中的溶液或悬浮液；或者例如是水包油或油包水型乳剂。已如上述，这些制剂可以通过任意适合的药学方法加以制备，制备方法包括使活性物质与赋形剂(它可以由一种或多种另外的组分组成)彼此接触的步骤。一般来说，组合物是这样制备的，将活性物质与液体和/或细分的固体赋形剂均匀一致地混合，然后如果需要的话，使产物成型。例如，片剂可以这样制备，压制化合物与酌情的一种或多种另外的组分的粉末或颗粒，或者使其成型。压制片可以这样制备，在适合的机械中，将自由流动形式、例如粉末或颗粒形式的化合物压片，酌情地化合物已与粘合剂、润滑剂、惰性稀释剂和/或一种(或多种)表面活性剂/分散剂混合成混合物。成型片可以这样制备，在适合的机械中，使粉状的用惰性液体稀释剂润湿的化合物成型。
适合于经口(舌下)给药的药物组合物包括锭剂，其中包含式(Ⅰ)化合物与矫味剂、通常是蔗糖和阿拉伯胶或黄芪胶，以及软锭剂，其中在惰性基质内包含该化合物，惰性基质例如是明胶和甘油或蔗糖和阿拉伯胶。
本发明进而也涉及式Ⅰ的异构体混合物和式Ⅰ的纯的非对映异构体。
本发明进而涉及式Ⅰ丙醇胺衍生物的制备方法。
制备式Ⅰ化合物方法的特征在于，其中R4取代的亚胺是从Ⅱ型的胺和Ⅲ型的醛制备的，其中的R4具有式Ⅰ给出的含义。为此，例如在20℃-150℃的温度下，加入或不加入一种酸，例如对甲苯磺酸，使胺Ⅱ与醛Ⅲ本身反应，或者在适合的溶剂中反应，溶剂例如为乙醇、甲苯或乙酸(a)。
被基团R1和R2取代的式Ⅶ酮化合物(其中R1和R2具有式Ⅰ给出的含义)通过文献已知方法或其相似方法加以制备。例如，在-80℃与20℃之间的温度下，甲基吡啶衍生物Ⅴ用适合的碱、例如正丁基锂金属化，并在四氢呋喃或另一种适合的溶剂中与相应的羧酸衍生物Ⅵ反应，例如羧酸二烷基酰胺或羧酸酯(基团X)(b)。
使Ⅳ型亚胺与Ⅶ型酮反应，得到Ⅷ型化合物，它们均被基团R1、R2和R4取代，其中R1、R2和R4具有式Ⅰ给出的含义。该反应例如可以这样进行，在20℃至150℃的温度下，将这两种化合物本身(没有溶剂)混合，随后加热，或者在适合的溶剂中，例如二氯甲烷、乙醇、甲苯、二甘醇二甲醚或十四烷中进行(c)。
借助于手性酸通过结晶法或色谱法，将Ⅷ型外消旋化合物拆分为Ⅸ和Ⅹ型纯的非对映异构体(手性酸例如是莰烷酸、五乙酰基葡糖酸、樟脑-10-磺酸、O-甲基扁桃酸或乳酸)(d)。
在-30℃与+40℃的温度下，在适合的溶剂中，例如甲醇、THF或THF/水，将Ⅸ或Ⅹ型酮化合物用NaBH4或另一种适合的还原剂还原，得到Ⅺ型羟基化合物，这些化合物有可能被基团R1、R2和R4取代，其中R1、R2和R4具有式Ⅰ给出的含义(e)。
在碱性或酸性条件下，例如使用KOH、NaOH或HCl，使手性酸在适合的溶剂中裂解，溶剂例如是甲醇、乙醇、THF或THF/水。随后通过文献已知的方法使硝基还原为胺，得到具有基团R1、R2和R4的Ⅻ型化合物(f)。
利用文献已知的方法，使Ⅻ型氨基化合物与烷基或酰基基团R3-Z-Y反应，其中Y代表离去基团，得到式Ⅰ化合物(g)。如果采用X-Z-Y作为该烷基或酰基基团，其中X是保护基团，那么得到的是中间体，该中间体能够进一步与烷基或酰基基团R3-Y反应，得到式Ⅰ化合物(h)。
式Ⅰ化合物和它们的药学上可接受的盐与生理学上的功能衍生物是理想的药物，用于脂质代谢障碍、特别是高脂血症的治疗。式Ⅰ化合物也适合于影响血清胆固醇水平，用于动脉硬化现象的预防和治疗。如果适当的话，该化合物也可以与他汀类药物联合给药，例如辛伐他汀、氟伐他汀、普伐他汀、cerivastatin、洛伐他汀或atorvastin。下列发现证实了根据本发明的化合物的药理学功效。
在测定对兔回肠刷状缘膜囊(Buerstensaummembranvesikeln)中[3H]-牛磺胆酸盐摄取的抑制作用的生物试验中测试根据本发明的化合物。如下进行抑制性试验：
1、兔回肠刷状缘膜囊的制备
通过所谓的Mg2+沉淀法，从小肠细胞制备刷状缘膜囊。通过静脉内注射0.5ml T61处死雄性新西兰兔(体重2至2.5kg),T61是2.5mg丁卡因HCl、100mg乙甲丁酰胺和25mg碘环三甲铵的水溶液。摘除回肠，用冰冷却的生理盐水洗涤。回肠的末端7/10(按口-直肠方向测量，即末端回肠，含有活性Na+-依赖性胆汁酸转运系统)用于制备刷状缘膜囊。在-80℃氮下，将小肠在聚合物袋内冷冻。为了制备膜囊，将冷冻后的小肠在30℃水浴中解冻。刮掉粘膜，将其悬浮在60ml冰冷却的12mM Tris-HCl缓冲液(pH7.1)/300mM甘露糖醇、5mM EGTA/10mg/l苯甲基磺酰氟/1mg/l大豆胰蛋白酶抑制剂(32U/mg)/0.5mg/l牛肺胰蛋白酶抑制剂(193U/mg)/5mg/l杆菌肽中。混合物用冰冷却的蒸馏水稀释至300ml后，在Ultraturrax(18-杆，IKA Werk Staufen,Germany)中在75％最大功率下匀化3分钟，同时用冰冷却。加入3ml 1MMgCl2溶液后(最终浓度10mM)，混合物在0℃下放置1分钟整。Mg2+的加入导致细胞膜聚集，并沉淀，而刷状缘膜除外。在3000xg(5000rpm,SS-34转子)下离心15分钟后，弃去沉淀，将含有刷状缘膜的上清液在48000xg(20000rpm,SS-34转子)下离心30分钟。弃去上清液，沉淀再用Potter Elvejhem匀化器(Braun,Melsungen,900rpm,10-冲程)在60ml 12mM Tris/HCl缓冲液(pH7.1)/60mM甘露糖醇、5mMEGTA中匀化。加入0.1ml 1M MgCl2溶液，在0℃下培养15分钟后，混合物再在3000xg下离心15分钟。上清液随后在48000xg(20000rpm,SS-34转子)下离心30分钟。将沉淀溶于30ml 10mMTris/Hepes缓冲液(pH7.4)/300mM甘露糖醇，在1000rpm下用20冲程Potter Elvejhem匀化器再悬浮。在48000xg(20000rpm,SS-34转子)下离心30分钟后，将沉淀溶于0.5至2ml Tris/Hepes缓冲液(pH7.4)/280mM甘露糖醇(最终浓度20mg/ml)，借助于27-量针结核菌素注射器再悬浮。膜囊在制备后立即用于转运试验，或者每份4mg贮存在-196℃液氮中。
2、对回肠刷状缘膜囊中Na+-依赖性[3H]-牛磺胆酸盐摄取的抑制作用
凭借所谓的膜过滤技术，测定上述刷状缘膜囊对底物的摄取作用。将10μl膜囊悬浮液滴(100μg蛋白质)吸移到聚苯乙烯培养管(11×70mm)壁上，培养管含有培养基以及有关的配体(90μl)。培养基含有0.75μl=0.75μCi[3H(G)]牛磺胆酸盐(比活度：2.1Ci/mMol)/0.5μl10mM牛磺胆酸盐/8.75μl钠转运缓冲液(10mM Tris/Hepes,(pH7.4)/100mM甘露糖醇/100mM NaCl)(Na-T-P)或8.75μl钾转运缓冲液(10mM Tris/Hepes,(pH7.4)/100mM甘露糖醇/100mM KCl)(K-T-P)和80μl所研究抑制剂在Na/T缓冲液或K/T缓冲液中的溶液，这因实验而异。将培养基通过聚偏二氟乙烯膜滤器(SYHV LO 4NS,0.4μm,4mmΦ,Milipore,Eschborn,Germany)过滤。将膜囊与培养基混合，开始测量转运作用。每批培养的牛磺胆酸盐浓度为50μM。经过所需的培养时间(通常为1分钟)后，加入1ml冰冷却的猝灭溶液(10mMTris/Hepes,(pH7.4)/150mM KCl)以终止转运。立即在25至35毫巴真空下，通过硝酸纤维素膜滤器(ME25,0.45μm，直径25mm,Schleicher&Schuell,Dassell,Germany)吸取所得混合物。滤器用5ml冰冷却的猝灭溶液清洗。
为了测量对放射性标记的牛磺胆酸盐的摄取作用，将膜滤器溶于4ml闪烁体Quickszint361(Zinsser Analytik GmbH,Frankfurt,Germany)，通过液体闪烁测量法，在TriCarb2500装置(CanberraPackard GmbH,Frankfurt,Germany)中测量放射性。装置已经借助于标准样本加以校准，并且任何可能存在的化学荧光已经加以校正后，得到测量值，以dpm(每分钟的分解量)表示。
分别在Na-T-P和K-T-P中测定对照值。Na-T-P和K-T-P之间摄取作用的差异代表Na+-依赖性转运。术语IC50Na+用于表示相对于对照水平，抑制50％Na+-依赖性转运的抑制剂浓度。
药理学数据包括一系列试验，这些试验研究了根据本发明的化合物与末端回肠中的肠内胆汁酸转运系统之间的相互作用。结果显示在表1中。
表1显示对兔回肠刷状缘膜囊中[3H]-牛磺胆酸盐摄取的抑制作用测量值(生物学试验)。所给出的数据是参照物质、即牛磺脱氧胆酸(TCDC)与所研究的供试物质的IC50Na值的商。
