      新型低膽固醇血化合物的制作方法

      文檔序號:3530081閱讀:626來源:國知局
      專利名稱:新型低膽固醇血化合物的制作方法
      技術(shù)領(lǐng)域
      本發(fā)明涉及可用于治療和預(yù)防動脈粥樣硬化和降低膽固醇水平的新型低膽固醇血化合物,本發(fā)明還涉及僅僅包含所述化合物或與其它活性藥劑組合而包含所述化合物的藥物組合物。
      背景技術(shù)
      在西方國家,動脈粥樣硬化冠心病是死亡和心血管發(fā)病的主要原因。動脈粥樣硬化冠心病的風(fēng)險因素包括高血壓、糖尿病、家族史、雄性、吸煙以及血清膽固醇。許多臨床研究已經(jīng)表明,高濃度血清膽固醇是動脈粥樣硬化發(fā)展和演變的主要影響因素。動脈粥樣硬化的特征在于在主動脈和小動脈中形成含膽固醇的斑塊。
      在哺乳動物中,1/3的血清膽固醇來源于通過在腸內(nèi)吸收進入身體的外源性飲食源,2/3的血清膽固醇通過在肝臟中內(nèi)源性全程合成得到,涉及復(fù)雜的一系列酶催化反應(yīng)和調(diào)節(jié)機制。
      最近研究表明,腸膽固醇吸收是與能量無關(guān)、蛋白質(zhì)介導(dǎo)的過程(Hauser,H.et al,Biochemistry 1998,37,17843-17850;Schulthess,G.et al,Biochemistry 2000,39,12623-12631;Werder,M.et al,Biochemistry 2001,40,11643-11650),而不是被動擴散過程。有助于腸膽固醇吸收的蛋白質(zhì)被證實為兩個位于刷緣膜上的清道夫受體(Hauser,et al,Biochemistry 1998,37,17843-17850;Werder,M.et al,Biochemistry2001,40,11643-11650)。體外和體內(nèi)動物實驗證實了這兩個清道夫受體在腸BBM中存在并證明了它們是蛋白質(zhì)介導(dǎo)膽固醇吸收的原因。
      各種2-吖丁啶酮化合物已經(jīng)被報道用于降低膽固醇和/或抑制在哺乳動物動脈壁中形成含膽固醇的病變例如WO 93/02048、WO 94/17038、WO 95/08532、PCT/US95/03196、美國專利5,633,246描述了在3-位上具有不同取代基的2-吖丁啶酮化合物,美國專利5,756,470公開了在4-位上具有不同取代基的2-吖丁啶酮。其它吖丁啶酮衍生物包括例如在歐洲專利199,630B1和歐洲專利申請337,549A1中公開的彈性蛋白酶抑制性取代的吖丁啶酮。這些2-吖丁啶酮的最主要代表物Ezetimibe(還以商品名稱ZetiaTM和Ezetrol而公知)已經(jīng)被用作單一療法中和結(jié)合斯他汀(statin)的雙重療法中的降低膽固醇的藥物。它是新型降低膽固醇的藥物的第一代表物,其通過靶向上述腸刷緣膜中的兩個清道夫受體來抑制腸膽固醇吸收。
      但是已經(jīng)表明,一旦給藥,2-吖丁啶酮容易被吸收并且大量被代謝為藥理活性葡糖苷酸,當(dāng)作為葡糖苷酸直接給藥時,超過95%的這種藥理活性葡糖苷酸保留在腸壁中(van Heek,M.et al.Br.J.Pharmacol.2000,129,1748-1754)。另外例如包括皮疹和血管性水腫(angiodema)的過敏反應(yīng)副作用已有報道。

      通過將β-內(nèi)酰胺轉(zhuǎn)化為硫代內(nèi)酰胺可以獲得式IIb化合物,最通常用Lawesson試劑來實施(Verkoyen,C.and Rademacher,P.Chem.Ber.1985,118,653-660;Yde,B.et al.Tetrahedron 1984,40,2047-2052;Steliou,K.;Mrani,M.J.Am.Chem.Soc.1982,104,3104-3106;Clader,J.W.et al.J.Med.Chem.1996,39,3684-3693)。
      通過將β-內(nèi)酰胺轉(zhuǎn)化為吖丁啶酮可以獲得式II c化合物,這可以通過本領(lǐng)域中許多公知的方法來實現(xiàn),例如(1)利用組合物AlHxCl3-x還原劑的直接一步還原,例如氯代二氫鋁烷或鋁烷(Jackson,M.B.et al.Aust.J.Chem.1983,36,779)或乙硼烷(Jackson,M.B.et al.Aust.J.Chem.1983,36,779-788)、AlHCl2和DIBAL-H(Yamashita,M.and Ojima,I.J.Am.Chem.Soc.1983,105,6339-6342;Ojima,I.et al.J.Org.Chem.1991,56,5263-5277);和(2)利用在實施例中概述的各種方法使1,3-氨基醇環(huán)化脫水(Soha r,P.et al.Chem.Soc.Perkin Trans.2 2000,287-293;Suga,H.et al.S.J.Am.Chem.Soc.1994,116,11197-11198;Barluenga,J.etal.Tetrahedron 1996,52,3095-3106;Obika,S.et al.Tetrahedron Lett.2003,44,5267-5270)。
      式IIIa化合物的制備根據(jù)流程圖I中所概述的來實現(xiàn),首先是所希望的反式-1,2-二取代烯烴的Sharpless不對稱氨基羥基化反應(yīng)(Demko,Z.P.et al.Org.Lett.2000,2,2221-2223;O′Brien,P.Angew.Chem.Int.Edit.Engl.1999,38,326-329;Bodkin,J.A.;McLeod,M.D.J.Chem.Soc.Perkin Trans.1 2002,2733-2746),接著利用色譜分離以獲得所需的區(qū)域異構(gòu)(regioisomeric)產(chǎn)物。對甲苯磺胺基團的隨后斷裂提供了用于Buchwald-Hartwig芳基化反應(yīng)的伯胺(Hartwig,J.F.Acc.Chem.Res.1998,31,852-860;Wolfe,J.P.;Wagaw,S.;Marcoux,J.F.;Buchwald,S.L.Acc.Chem.Res.1998,31,805-818),隨后暴露于三光氣中最終產(chǎn)生所需的式IIIa的唑烷酮。作為替代,它們可以根據(jù)實施例中所概述的那樣而獲得。
      流程圖I利用現(xiàn)有技術(shù)中已知方法,根據(jù)流程圖II中所描述的方法可以獲得式IIIe化合物(Mish,M.R.et al.J.Am.Chem.Soc.1997,119,8379-8380;Guerra,F(xiàn).M.et al.Org.Lett.2000,2,4265-4267)。作為選擇,其中Sp2不是共價鍵的化合物可以根據(jù)實施例中所闡述的方法來合成。
      流程圖II以類似于在文獻中所報道的方法來實施式IIIc吡唑烷酮的制備,如流程圖III所示(Lou,B.S.et al.J.Org.Chem.1995,60,5509-5514;Tomkinson,N.C.O.ChemistryChemistry of Carbon Compounds(第二版),Asymmetric Catalysis,Ed.M.Sainsbury 2001,5,199-258)。
      流程圖III已經(jīng)發(fā)現(xiàn),在例如Rb或Sp3基團中使用磺酸酯鍵、即將碳水化合物鍵合至亞苯環(huán)是特別有益的,這是由于與C-葡糖苷鍵的更強非極性特性相比,S=O雙鍵可用作氫鍵受體。這種鍵還沒有被報道用于鍵合碳水化合物和其它類型的分子。此外,這種鍵是不可水解的,即碳水化合物不可水解離。
      還發(fā)現(xiàn),本發(fā)明的化合物表現(xiàn)出優(yōu)異的藥理活性并且能夠克服利用現(xiàn)有技術(shù)中成熟方法的已知低膽固醇血藥劑的缺點,例如它們在對于兔刷緣膜泡囊(BBMV)中以及Caco-2細胞中的膽固醇攝取的IC50值評估(Hauser,H.et al,Biochemistry1998,37,17843-17850;Schulthess,G.et al,Biochemistry 2000,39,12623-12631;Werder,M.et al.Biochemistry 2001,40,11643-11650;Boffelli,D.et al.FEBS Lett.1997,411,7-11)(另見表I)。
      因此本發(fā)明的化合物例如式I化合物和它們的藥學(xué)可接受的酸加成鹽表現(xiàn)出藥理活性并因此可用作藥物。本發(fā)明的化合物已經(jīng)表現(xiàn)出有效地抑制膽固醇的吸收并由此可用于治療和/或預(yù)防動脈粥樣硬化以及降低膽固醇水平。
      因此,在另一方面,本發(fā)明涉及治療和/或預(yù)防動脈粥樣硬化、降低膽固醇水平和治療或預(yù)防血管病的方法,包括給需要這種治療的哺乳動物施加有效量的式I化合物,特別是式II和III化合物。
      可以例如以含有治療有效量的活性成分的藥物組合物的形式來使用式I的新型化合物,如果適當(dāng),可以和適合于腸內(nèi)給藥例如口服、腸胃外給藥的無機或有機、固體或液體、藥學(xué)可接受載體一起使用。因此將含有有效成分的片劑或膠囊結(jié)合下列物質(zhì)一起使用稀釋劑、普通乳糖、葡萄糖、蔗糖、甘露醇、山梨醇、纖維素,和/或潤滑劑例如硅藻土、滑石、硬脂酸或其鹽例如硬脂酸鎂或硬脂酸鈣,和/或聚乙二醇。片劑還可以含有粘合劑,典型的是硅酸鎂鋁、淀粉通常是玉米淀粉、小麥淀粉、大米淀粉或木薯淀粉、明膠、黃蓍膠、甲基纖維素、羧基甲基纖維素鈉和/或聚乙烯吡咯烷酮,根據(jù)需要還含有崩解劑和/或泡騰混合物、或吸收劑、著色劑、調(diào)味劑和甜味劑,所述崩解劑通常是淀粉、瓊脂、褐藻酸或其鹽例如藻酸鈉。
      因此,在另一方面,本發(fā)明涉及一種藥物組合物,該組合物包含式I化合物、特別是式II和III化合物(以及任選的其它治療有效藥劑),以及藥學(xué)上可接受的載體,用于治療或預(yù)防動脈粥樣硬化或降低膽固醇水平。
