Description
本發明係關於如下通式之化合物,
其中:R1 係苯基或吡啶基,其可視情況經一個、兩個或三個選自鹵素、經鹵素取代之低碳數烷基、低碳數烷氧基、經鹵素取代之低碳數烷氧基、氰基或S(O)2-低碳數烷基之取代基取代,或係嗎啉基、二氫吡喃基或哌啶基,其中哌啶基可視情況經鹵素取代,或係C(O)O-低碳數烷基;R2 係氫;R3 係氫、經鹵素取代之低碳數烷基、-(CH2)n-S(O)2-低碳數烷基、-(CH2)n-環烷基或-(CH2)n-低碳數烷氧基;R4 係氫或低碳數烷基;n係0、1或2;或其醫藥上可接受之酸加成鹽、外消旋混合物或其相應的對映異構體及/或其光學異構體。
現已證明本發明之化合物刺激自神經幹細胞(NSC)之神經生成。神經生成發生於開發中及成體大腦。概念上,神經生成之該過程可被分為四個步驟:(i)NSC之增殖;(ii)NSC之神經元命運決定;(iii)新神
經元之存活及成熟;及(iv)新神經元進入神經元網路之功能整合。
成體神經生成係發生於貫穿成體大腦之生命中之發展過程,藉以從成體神經幹細胞中生成新功能性神經元。生理條件下之構成性成體神經生成主要發生於兩個「神經性」大腦區域,1)海馬體之齒狀回中之顆粒下層區域(SGZ),在其中生成新齒狀顆粒細胞,2)側腦室之腦室下層區域(SVZ),在其中生成新神經元及然後經由嘴側遷移流(RMS)遷移至嗅球以成為中間神經元。
廣泛之證據顯示海馬成體神經生成在認知及情緒狀態中起到重要作用,儘管精確功能仍難懂。已爭論的是相對小數量的新生顆粒神經元可影響整體大腦功能,因為它們可在齒狀回中神經支配許多中間神經元,每一個中間神經元抑制數百個成熟的顆粒細胞,導致神經生成依賴性反饋抑制。在本文中,與用於啟動新生神經元之低臨限值組合觸發反應的極細微變化。此過程之干擾可行為上表現與精神疾病相關之模組分離之缺陷。例如,成體海馬神經生成與認知及情緒能力相關,例如,身體鍛煉、曝露於強化環境及典型抗抑鬱劑相伴促進成體海馬神經生成及認知及/或情緒狀態,而慢性壓力、抑鬱症、失眠及老化降低成體神經生成且與消極的認知及/或情緒狀態相關(Neuron 70,2011年5月26日,第582至588頁及第687至702頁;WO 2008/046072)。有趣的是,抗抑鬱劑促進海馬成體神經生成及其對某些行為之作用需要神經生成之刺激。在其他成體CNS區域中之神經生成通常被認為在正常生理條件下非常有限,但在受傷(諸如中風及中樞及外周大腦損傷)後可被引發。
因此,據信成體神經生成之刺激代表針對正常老化及尤其針對多種神經退化性及神經精神性疾病(包括精神分裂症、強迫型人格障礙、重性抑鬱症、躁鬱症、焦慮症、癲癇症、視網膜變性、腦外傷、脊椎損傷、創傷後壓力症、恐慌症、帕金森氏(Parkinson’s)病、癡
呆、阿茲海默氏(Alzheimer’s)病、輕度認知障礙、化療引起之認知功能障礙(「化療腦(chemobrain)」)、唐氏(Down)症侯群、自閉症譜系障礙、聽力損失(Neuroscience,167(2010)1216-1226;Nature Medicine,第11卷,3號,(2005),271-276)、耳鳴、脊髓小腦性共濟失調、肌萎縮性脊髓側索硬化症、多發性硬化、亨廷頓氏(Huntington’s)病、中風及歸因於放射治療、慢性壓力或濫用神經活性藥物(諸如酒精、鴉片劑、甲基苯丙胺、苯環己哌啶及可卡因)之紊亂)之神經再生治療目標(US 2012/0022096)。
成體神經生成之刺激亦代表針對視神經病變(S.Isenmann、A.Kretz、A.Cellerino,Progress in Retinal and Eye Research,22,(2003)483)及黃斑變性(G.Landa、O.Butovsky、J.Shoshani、M.Schwartz、A.Pollack,Current Eye Research 33,(2008)1011)之治療目標。
因此,成體神經生成之化學刺激提供新的再生途徑及開發用於治療神經疾病及神經精神病之新穎藥物之機會。
因此,本發明之目標為識別調節神經生成之化合物。已發現式I之化合物在該區域有活性且因此其可用於治療精神分裂症、強迫型人格障礙、重抑鬱症、躁鬱症、焦慮症、正常老化、癲癇症、視網膜變性、腦外傷、脊椎損傷、創傷後壓力症、恐慌症、帕金森氏病、癡呆、阿茲海默氏病、認知障礙、化療引起之認知功能障礙(「化療腦」)、唐氏症侯群、自閉症譜系障礙、聽力損失、耳鳴、脊髓小腦性共濟失調、肌萎縮性脊髓側索硬化症、多發性硬化、亨廷頓氏病、中風及歸因於放射治療、慢性壓力、視神經病變或黃斑變性或神經活性藥物(諸如酒精、鴉片劑、甲基苯丙胺、苯環己哌啶及可卡因)濫用之紊亂。
式I之化合物之最佳適應症為阿茲海默氏病、抑鬱症、焦慮症及
中風。

依照下文給出之測試研究該等化合物。
小分子之神經特性係基於人類胚胎幹細胞衍生之神經幹細胞(NSC)之增殖而測定,NSC係經由如上所述之雙重smad抑制而起源。(Chambers,S.M.等人,Highly efficient neural conversion of human ES and iPS cells by dual inhibition of SMAD signaling,Nature biotechnology,2009.27(3):第275至80頁。)
化合物反應係在4天之培育期後藉由基於ATP水平(Promega:CellTiterGlo®)之細胞增加而測量。
將NSC解凍並擴增至3段。在第14天,將NSC以21000個細胞/cm2之細胞密度,38μl之培養基體積接種於經Polyornithin/層黏連蛋白(Laminin)塗覆之384孔板中。
在細胞接種4小時後,加入2μl體積之化合物溶液。稀釋化合物之儲備溶液(水,5%DMSO)以獲得範圍自8μM至8nM的劑量反應(11個點,稀釋因數為2)。運行對照以一致地測定細胞之神經特性:負(中性)對照為細胞培養基(最終DMSO濃度:0.25%)。
正對照為:
1.細胞培養基+100ng/ml FGF2(最終DMSO濃度:0.1%)
2.細胞培養基+20ng/ml EGF(最終DMSO濃度:0.1%)
3.細胞培養基+100ng/ml Wnt3a(最終DMSO濃度:0.1%)
在37℃、5%CO2下培養4天之後,量化每個孔中之ATP量。ATP濃度與細胞數量成正比例。藉由使用Promega CellTiterGlo®套組量化ATP。CellTiterGlo®試劑包含細胞裂解緩衝液、熱穩定螢光素酶(UltraGloTM重組螢光素酶)、鎂及蟲螢光素。蟲螢光素與ATP反應生成氧化蟲螢光素、AMP及光。發光信號與ATP含量成正比例。
藉由取16個負對照孔之平均值測定每塊檢定板之負(中性)對照之值。針對每個化合物以(化合物/負對照)*100計算神經生成化合物反應。
測定每個測試之化合物之來自劑量反應曲線之EC150之值。EC150為達到對照(100%)之150%活性時之化合物濃度。較佳化合物顯示EC150(μM)在<2.5μM之範圍內,如下表1中展示。
式I之化合物及式I之化合物之醫藥上可接受之鹽可用作藥物,例如以醫藥製劑之形式。醫藥製劑可口服,例如以錠劑、包衣錠劑、糖
衣片、硬及軟明膠膠囊、溶液、乳液或懸浮液之形式。然而投藥亦可經直腸達成,例如以栓劑之形式,或非經腸達成,例如以注射溶液之形式。
