Abstract
本發明提供式(I)化合物:□包括此等化合物之組合物;此等化合物於治療上之用途(例如,治療或預防其中與血漿激肽釋放酶活性有關之疾病或病狀);及使用此等化合物治療患者之方法;其中R1至R9如本文所定義。
Description
本發明係關於苯甲胺衍生物,及含此等衍生物之醫藥組合物及其用途。
本發明苯甲胺衍生物係血漿激肽釋放酶之抑制劑,且具有多種治療應用,尤其於治療與糖尿病性視網膜病及糖尿病性黃斑水腫相關之視網膜血管通透性。
血漿激肽釋放酶係一種可以使激肽原(kininogen)釋放出激肽(kinin)之胰蛋白酶樣絲胺酸蛋白酶(參見K.D.Bhoola等人,「Kallikrein-Kinin Cascade」,Encyclopedia of Respiratory Medicine,p483-493;J.W.Bryant等人,「Human plasma kallikrein-kinin system:Physiological and biochemical parameters」Cardiovascular and haematological agents in medicinal chemistry,7,p234-250,2009;K.D.Bhoola等人,Pharmacological Rev.,1992,44,1;及D.J.Campbell,「Towards understanding the kallikrein-kinin system:insights from the measurement of kinin peptides」,Brazilian Journal of Medical and Biological Research 2000,33,665-677)。雖然血漿激肽釋放酶在血液凝集級聯機制(blood coagulation cascade)中未涉及緩激肽(bradykinin)的釋放或酵素切解,但其卻係人體內固有凝血級聯機制之重要成員。血漿前激肽釋放酶係由單一基因所編碼,並係在肝臟中合成。肝細胞會以活性的血漿前激肽釋放酶分泌,
該血漿前激肽釋放酶會與高分子量激肽原鍵結成為異二聚體複合物於血漿中循環,其經活化會產生具有活性的血漿激肽釋放酶。激肽是可透過G-蛋白偶合受體發揮作用的炎症之強力媒介體,且激肽的拮抗劑(諸如,緩激肽拮抗劑)先前業已經研究可作為治療多種病症之潛在治療劑(F.Marceau and D.Regoli,Nature Rev.,Drug Discovery,2004,3,845-852)。
血漿激肽釋放酶被認為在多種炎症病症中會發揮作用。
血漿激肽釋放酶之主要抑制劑為絲胺酸蛋白酶抑制劑C1酯酶抑制劑(serpin C1 esterase inhibitor)。具有C1酯酶抑制劑遺傳缺陷之患者身受遺傳性血管性水腫(hereditary angioedema;HAE)之苦,會導致臉部、手、咽喉、胃腸道、及生殖器的間歇性腫脹。急性發病期間所形成之水泡包含高濃度血漿激肽釋放酶,該酵素會切解高分子量激肽原釋放出緩激肽,因而導致血管通透性增加。利用大蛋白血漿激肽釋放酶抑制劑的治療業經證明可藉由阻礙會造成血管通透性增加之緩激肽的釋放而能有效治療HAE(A.Lehmann「Ecallantide(DX-88),a plasma kallikrein inhibitor for the treatment of hereditary angioedema and the prevention of blood loss in on-pump cardiothoracic surgery」Expert Opin.Biol.Ther.8,p1187-99)。
血漿激肽釋放酶-激肽系統(plasma kallikrein-kinin system)在患有晚期糖尿病性黃斑水腫之患者中異常地充足。最近已發表,血漿激肽釋放酶會造成糖尿病大鼠之視
網膜血管功能障礙(A.Clermont等人「Plasma kallikrein mediates retinal vascular dysfunction and induces retinal thickening in diabetic rats」Diabetes,2011,60,p1590-98),除此之外,投與血漿激肽釋放酶抑制劑ASP-440可紓緩糖尿病大鼠之視網膜血管通透性及視網膜血液流動異常。因此,血漿激肽釋放酶抑制劑應該具有減輕與糖尿病性視網膜病及糖尿病性黃斑水腫相關之視網膜血管通透性的治療效用。
先前業已描述合成小分子血漿激肽釋放酶抑制劑,例如Garrett等人(「Peptide aldehyde...」J.Peptide Res.52,p62-71(1998))、T.Griesbacher等人(「Involvement of tissue kallikrein but not plasma kallikrein in the development of symptoms mediated by endogenous kinins in acute pancreatitus in rats」British Journal of Pharmacology 137,p692-700(2002))、Evans(「Selective dipeptide inhibitors of kallikrein」WO 03/076458)、Szelke等人(「Kininogenase inhibitors」WO 92/04371)、D.M.Evans等人(Immunolph armacology,32,p115-116(1996))、Szelke等人(「Kininogen inhibitors」WO 95/07921)、Antonsson等人(「New peptides derivatives」WO 94/29335)、J.Stürzbecher等人(Brazilian J.Med.Biol.Res 27,p1929-34(1994))、Kettner等人(US 5,187,157)、N.Teno等人(Chem.Pharm.Bull.41,p1079-1090(1993))、W.B.Young等人(「Small molecule inhibitors of plasma kallikrein」Bioorg.
Med.Chem.Letts.16,p2034-2036(2006))、Okada等人(「Development of potent and selective plasmin and plasma kallikrein inhibitors and studies on the structure-activity relationship」Chem.Pharm.Bull.48,p1964-72(2000))、Steinmetzer等人(「Trypsin-like serine protease inhibitors and their preparation and use」WO 08/049595)、Zhang等人(「Discovery of highly potent small molecule kallikrein inhibitors」Medicinal Chemistry 2,p545-553(2006))、Sinha等人(「Inhibitors of plasma kallikrein」WO 08/016883),及Brandl等人(「N-((6-amino-pyridin-3-yl)methyl)-heteroaryl-carboxamides as inhibitors of plasma kallikrein」WO 2012/017020)。另外,Steinmetzer等人(「Serine protease inhibitors」WO 2012/004678)描述環狀肽類似物,該等類似物是人類纖溶酶(plasmin)及血漿激肽釋放酶之抑制劑。
至今,沒有小分子合成性血漿激肽釋放酶抑制劑係經批准作為醫學用途。已知技藝中所述之分子受到侷限性,諸如在諸如KLK1、凝血酶及其他絲胺酸蛋白酶有關的酵素方面具有不良的選擇性及不良的口服可利性。大蛋白血漿激肽釋放酶抑制劑存在過敏性休克反應之風險,正如已報導之曲安奈德(Ecallantide)。因此,仍有可選擇性抑制血漿激肽釋放酶、但不會誘發過敏性休克反應且具適口性之化合物之需求。另外,技藝中已知之分子具有強極性及可電子化胍或脒官能性的特徵。眾所周知,該等官能性可能
侷限於腸通透性,且因此局限於口服可利用性。
糖尿病之其他併發症,諸如腦出血、腎病、心肌病及神經病變,所有與血漿激肽釋放酶相關之併發症亦可視為血漿激肽釋放酶抑制劑之標的。
本發明係關於一系列為血漿激肽釋放酶之抑制劑的苯甲胺。該等化合物顯示對血漿激肽釋放酶具有良好選擇性,且可潛在有效治療下列病狀:受損視力、糖尿病性視網膜病、黃斑水腫、遺傳性血管性水腫、糖尿病、胰腺炎、腦出血、腎病、心肌症、神經病變、發炎性腸病、關節炎、炎症、敗血性休克、低血壓、癌症、成人呼吸窘迫症候群、彌漫性血管內凝血症、心肺繞道手術及術後出血。本發明進一步係關於該等抑制劑之醫藥組合物、該等組合物作為治療劑之用途及利用該等組合物治療之方法。

以投與至人類患者而言,本發明化合物之每日總劑量典型地係在0.01 mg至1000 mg範圍,或介於0.1 mg至250 mg之間,或介於1 mg至50 mg之間,當然要取決於投與模式。例如,若藉由玻璃體內注射投與,預計本發明化合物將偶爾給藥,例如每月一次。在此狀況下,預計劑量介於0.5 mg至20 mg之間,諸如介於1 mg至10 mg之間。若更頻繁給藥,例如每日一次,預計採用介於0.005 mg至0.02 mg低很多的劑量。

本發明化合物可根據以下方案及實例之步驟,使用適當的物質製備,並進一步以下文所提供之特定實例加以舉例說明。除此之外,藉由利用本文所述之步驟,一般技藝者可輕易地製備屬於本文所主張之本發明範圍內之其他化合物。然而,實例中所說明之化合物不應理解為形成認為是本發明的唯一種類物。實例進一步闡明製備本發明化合物之細節。熟習此項技藝者可輕易地理解以下用於製備該等化合物之製備步驟之條件及方法之已知變項。
本發明化合物可以其醫藥上可接受之鹽之形式分離出來,諸如彼等上文先前所述者。
製備本發明化合物時所用的中間產物之反應性官能團(例如,羥基、胺基、硫氫基或羧基)有必要加以保護,以避免其不必要地參與會導致化合物形成之反應。可使用習知保護性基團,例如彼等由T.W.Greene及P.G.M.Wuts描述於「Protective groups in organic chemistry」John Wiley and Sons,4th Edition,2006者。例如,適於本文使用之常見保護基團為第三-丁氧基羰基(Boc),其藉由使用一種含於有機溶劑(諸如,二氯甲烷)之酸(諸如,三氟乙酸或氯化氫)處理即可輕易地移除。或者,胺基保護基團可為苄基氧羰基(Z)基團,其藉由使用鈀觸媒在氫氣氛下進行氫化作用即可移除,或胺基保護基團可為9-茀甲氧羰基(Fmoc)基團,其藉由含於有機溶劑之二級有機胺(諸如,二乙胺或六氫吡啶)溶液即可移除。羧基基團典型地係以諸如甲基酯、乙基酯、苄基酯或第三丁基酯等酯類身分加以保護,該等甲基、乙基、苄基或第三丁基基團可全部藉由在鹼(諸如,氫氧化鋰或氫氧化鈉)存在下進行水解作用而加以移除。苄基保護基團亦可藉由使用鈀觸媒在氫氣氛下進行氫化作用而加以移除,同時第三丁基基團亦可藉由三氟乙酸而加以移除。或者,三氯乙酯保護基團係使用含於乙酸之鋅而加以移除。適於本文使用之常見羥基保護基為甲醚,去保護條件包括於48%水性HBr中迴流1-24小時,或藉由於二氯甲烷中與三溴甲硼烷(borane tribromide)攪拌1-
24小時。或者,當羥基基團係以苄醚身分保護時,去保護條件包括在氫氣氛下使用鈀觸媒進行氫化作用。
根據通式I之化合物可使用習知合成方法加以製備,例如(但不限於)方案1中所概述之途徑。在典型的第一步驟中,利用標準肽胺基偶聯作用條件,將胺(2)偶合至經活化α胺基酸(1),該α胺基酸(1)係使用標準保護基團(諸如,第三-丁氧基羰基(Boc)、苄基氧羰基(Z)或9-茀甲氧羰基(Fmoc))將胺基適當地保護。活化基團(X)係為N-羥基琥珀醯亞胺。該等基團之用途在此項技藝中係眾所周知的。當R5或R9(在方案1中係以「芳基」顯示)具有諸如胺或羧酸的反應性官能團時,此基團亦要被保護。其他標準肽胺基偶聯方法包括酸與胺在存在羥基苯并***及碳二亞胺(諸如,水溶性碳二亞胺)下反應,或與2-(1H-苯并***-1-基)-1,1,3,3-四甲基銨六氟磷酸鹽或苯并***-1-基-氧-參-吡咯啶并-鏻六氟磷酸鹽或溴-參吡咯啶并-鏻六氟磷酸鹽在存在有機鹼(諸如,三乙胺、二異丙基乙胺或N-甲基嗎啉)反應。在典型的第二步驟中,保護基團係使用如先前所述之標準方法加以移除的。
方案1中所舉例途徑,在接著的第三步驟係經由另一標準肽胺基偶聯繼續進行,並在第四步驟中利用如先前所描述之標準條件移除Boc保護基。接著,在第五步驟,7中所示之胺係典型地經基團R1烷基化或醯基化。醯化作用可藉由使用醯化劑(諸如,醯基氯,例如,乙醯氯或苯甲醯氯)於存在鹼(典型地為三級胺鹼,諸如,三乙胺或二異丙基
乙胺)下進行。典型地,烷化作用可藉由使用烷基鹵處理或藉由還原烷基化作用進行。典型地,在還原烷基化作用的過程中,室溫下,於存在含於合適溶劑(諸如,甲醇)之合適還原劑(諸如,氰基硼氫化鈉或乙醯氧基硼氫化鈉)下,將胺與醛或酮反應。接著,將所得腈化合物8藉由氫化作用加以還原。8轉化為10可藉由於合適溶劑(諸如,甲醇)中,在存在合適觸媒(諸如,炭上鈀觸媒)下藉由氫化作用直接將腈還原,或在室溫下,於合適溶劑(諸如,甲醇)中,與合適氫硼化物在存在合適過渡金屬(諸如,氯化鈷或氯化鎳)下發生還原作用,以單一步驟即可實現。或者,(利用(例如)如S.Caddick等人,Tetrahedron Lett.,2000,41,3513中所描述之方法)分離出經第三-丁氧基羰基(Boc)保護之胺9,隨後藉由先前所述標準方法進行去保護作用,以產生胺10。
本發明藉由以下非限定性實例說明,其中使用以下縮寫詞及定義:

實例3化合物的活性已在大鼠中利用此活體內模型建立。在時間點為0時,大鼠以玻璃體內注射法接受5 μL磷酸鹽緩衝生理食鹽水(PBS)、CH-3457(血漿激肽釋放酶抑制劑陽性對照組)(10 μM)或實例3化合物(1 μM)。30分鐘後,以玻璃體內注射法給予第2次5 μL PBS或CA-I(200 ng/眼)。15分鐘後,輸注10%螢光素鈉,並在首次IVT注射75分鐘後,以玻璃體螢光光度測量法測定視網膜血管通透性(retinal vascular permeability;RVP)。實例3化合物的數據呈現於圖1中,其中較低虛線表示接受PBS/PBS後之基礎RVP,而較高虛線表示最大的刺激作用。相對於以玻璃體內注射法僅注射PBS而言,僅注射1 μM實例3化合物對基礎RVP沒有影響(3.64±0.48對3.29±0.21)。以玻璃體內注射法注射實例3化合物會使(受到CA-I注射刺激)RVP減少
53±21%。

眼部組織濃度數據呈現於圖2中,其中代表每一眼部組織濃度之實線係為每隻兔子左眼及右眼的平均值。在7天內,實例3化合物在眼部組織濃度降低極微。IVT投與後,血漿中實例3化合物的濃度在所有時間點上皆低於1 ng/mL。
圖1顯示實例3化合物及CH-3457(陽性對照組;血漿激肽釋放酶抑制劑)在斯潑累格.多雷(Sprague Dawley)大鼠中對經CA-I刺激的RVP之抑制作用。
