本發明係關於某些作為PDE4酶抑制劑之經取代之吡啶及吡化合物;該等化合物之衍生物;該等化合物之組合物;製造其之方法;及其在眾多種方法中之用途,該等方法包含檢測及顯影技術;增強神經元可塑性;治療神經病症,包含精神病學、神經退化性、腦血管、認知及運動障礙;提供神經保護;增強認知及運動訓練之效率;幫助神經恢復及神經復健;及治療外周病症,包含發炎及腎病症。
哺乳動物磷酸二酯酶(PDE)係一組基於受質特異性、抑制劑敏感性及最新地序列同源性分成11個家族(PDE1-11)之密切相關之酶。該11個家族係由21個基因編碼,從而提供具有多個成員之若干家族。所有哺乳動物PDE共享位於蛋白質COOH端部分中之保守催化結構域。在含有GAF之PDE中,一或兩個GAF可提供二聚化接觸。此外,該等蛋白質中每一者中之一個GAF提供別位cGMP結合(PDE2、PDE5、
PDE6、PDE11)、別位cAMP結合(PDE10)及催化位點功能之調控(PDE2、PDE5、PDE6)。PDE之其他家族具有多個子結構域之有助於調控活性之獨特補體(UCR、NHR、PAS、膜締合)。PDE 1、2、3及4在許多組織中表現,而其他PDE更受限制。在大多數細胞中,PDE3及PDE4提供cAMP水解活性之主要部分(Francis,Physiological Reviews,2011,91,651-690)。
PDE4家族包含具有20種以上剪接變體之四個亞型(PDE4A、B、C及D),從而使其成為最大PDE子家族中之一者(Bender及Beavo,2006)。PDE4酶使cAMP水解,且對於cAMP之受質表觀Km為1-5μM。PDE4酶據報導係由兩個上部控制區(UCR)結構域來調控。端視不同的RNA剪接,可將PDE4變體區分為兩個主要亞群:長式及短式(Conti等人,J Biol Chem.,2003,278,5493-5496)。業內已報導9種剪接變體。PDE4D1、4D2及4D6皆係缺少UCR之較短形式。PDE4D3、4D4、4D5、4D7、4D8及4D9係含有對其亞細胞定位至關重要之UCR及N端結構域二者之較長形式(Bender及Beavo,2006)。長式PDE4D3活性係經由N端UCR1中之Ser54之PKA磷酸化來增加(Alvarez等人,Mol Pharmacol.,1995,48,616-622;Sette等人,J Biol Chem.,1996,271,16526-16534)。相反,PDE4D3 C端中之Ser597之Erk2磷酸化使催化活性降低。一或若干PDE4D亞型在大多數所測試組織中始終表現,包含皮質、海馬、小腦、心臟、肝臟、腎臟、肺及睪丸(Richter等人,Biochem.J.,2005,388,803-811)。業內認為PDE4D亞型之定位及調控允許嚴格及局部調控cAMP含量,此可限制信號在特定亞細胞隔室中之傳播。
多個研究已強調通常PDE、且尤其PDE4在調節調控許多生理學過程之細胞內信號傳導途徑方面的作用,包含彼等潛在神經可塑性、認知及記憶。具體而言,PDE在涉及第二信使cAMP及cGMP之細胞內
信號轉導途徑中起重要作用。該等環狀核苷酸用作普遍存在於所有哺乳動物細胞中之細胞內信號傳導分子。PDE酶藉由斷裂磷酸二酯鍵來水解cAMP及cGMP以形成相應的單磷酸核苷(Bender及Beavo,Pharmacol.Rev.,2006,58(3),488-520)。PDE活性係與腺苷酸環化酶(AC)及鳥苷酸環化酶(GC)活性協同經由直接效應子及反饋途徑進行調節,由此將cAMP及cGMP含量維持在用於因應信號之最佳範圍內。細胞外信號調節細胞內環狀核苷酸濃度之能力允許細胞越過細胞膜邊界因應外部刺激物。
環狀核苷酸信號傳導級聯已適用於因應許多轉導系統,包含G蛋白偶合受體(GPCR)以及電位及配體門控離子通道。環狀核苷酸將其細胞中之信號傳送通過眾多種三級元件。該等元件中之最佳闡述者係cAMP依賴性蛋白激酶(PKA)及cGMP依賴性蛋白激酶(PKG)。環狀核苷酸至每一酶之結合使得能夠磷酸化在信號傳導級聯中用作效應子或其他元件之下游酶及蛋白質。對記憶形成尤其重要者係PKA之cAMP活化,其使cAMP反應元件結合蛋白(CREB)磷酸化。pCREB係經活化之轉錄因子,其結合至特定DNA座且起始多種參與神經元可塑性之基因之轉錄。活體外及活體內研究二者皆已將環狀核苷酸濃度之變化與認知功能連接之生物化學及生理學過程相關聯(Kelly及Brandon,Progress in Brain Research,2009,179,67-73;Schmidt,Current Topics in Medicinal Chemistry,2010,10,222-230)。業內已確立突觸處之信號強度及同步活動之程度可變化,此可使具體突觸處之傳送增效。長期增效(LTP)係該等過程中之最佳闡述者且已知由cAMP及cGMP信號傳導級聯二者來調節。
根據PDE4樣果蠅屬(Drosophila)學習突變體dunce(dnc基因,PDE4亞型之環狀核苷酸磷酸二酯酶)之發現,精力集中於PDE4在記憶中之作用(Yun及Davis,Nucleic Acids Research,1989,17(20),8313-
8326)。當在具有負強化(Dudai等人,Proc Natl Acad Sci.,1976,73(5),1684-1688;Dudai Y.,Proc Natl Acad Sci.,1983,80(17),5445-5448;Tully及Quinn,Journal of Comparative Physiology,1985,157(2),263-77)或正強化(Tempel等人,Proc Natl Acad Sci.,1983,80(5),1482-1486)之若干不同的嗅覺聯想學習情況下測試時,dnc突變體蒼蠅在獲取及/或短期記憶方面有缺損。在哺乳動物中,PDE4D基因敲除動物展示在抗抑鬱劑懸尾及強迫游泳測試模型中降低的不動性(Zhang等人,Neuropsychopharmacology,2002,27(4),587-595),在海馬CA1切片中增強的活體外LTP(Rutten等人,Eur.J.Neurosci.,2008,28(3),625-632)及在八臂迷宮、目標識別及Morris水迷宮實驗中增強的記憶(Li等人,J.Neurosci.,2011,31,172-183)。
該等觀察強調關注PDE抑制(包含PDE4抑制)作為多種病症及認知增強之治療靶。例如,藉由增加cAMP含量,該等抑制劑可用於治療諸如帕金森氏病(Parkinson's Disease)及阿茲海默氏病(Alzheimer's Disease)等神經退化性病症中之認知衰退以及通常改善正常、患病及衰老個體之認知。業內已報導眾多種小分子PDE4酶抑制劑,例如氮雜-橋接二環(DeCODE Genetics;國際專利申請公開案WO 2010/059836,2010年5月27日);N-經取代之苯胺(Memory Pharmaceuticals公司;國際專利申請公開案WO 2010/003084,2010年1月7日);二芳基(DeCODE Genetics;國際專利申請公開案WO 2009/067600,2009年5月28日,WO 2009/067621,2009年5月28日);苯并噻唑及苯并噁唑(DeCODE Genetics;美國專利申請公開案US 2009/0130076,2009年5月21日);兒茶酚(DeCODE Genetics;美國專利申請公開案US 2009/0131530,2009年5月21日)、蝶啶(Boehringer Ingelheim International G.m.b.H.;美國專利7,674,788,2007年11月29日);雜芳基吡唑(Memory Pharmaceuticals公司;國際專利申請公開案
WO 2007/123953,2007年11月1日);萘啶(Glaxo Group Limited;國際專利申請公開案WO 2006/053784,2006年5月26日);六氫吡基二氫噻吩并嘧啶(Boehringer Ingelheim International G.m.b.H.;歐洲專利1,874,781,2009年6月24日);菸醯胺衍生物(Pfizer;美國專利申請公開案US 2005/0020587,2005年1月27日);雜芳基甲基苯基胺(Memory Pharmaceuticals公司;美國專利7,087,625,2006年8月8日);萘啶(Novartis AG;歐洲專利1,443,925,2007年12月26日;美國專利7,468,370,2008年12月23日)。
然而,PDE4抑制劑通常與多種通常限制其有用性及耐受性之副作用相關,最值得注意的是嘔吐(例如,Giembycz,Curr.Opin.Pharm.2005,5,238-244)。因此,業內期望研發出經改善之PDE4抑制劑,例如彼等顯示較高效能、較強特異性及較佳副作用特徵者。本發明藉由揭示作為強效及耐受良好之PDE4抑制劑之經取代之吡啶及吡化合物來滿足業內之該等及其他需要。

本文所給出之任何式意欲代表具有由結構式繪示之結構以及某些變化或形式之化合物。具體而言,本文所給出之任何式之化合物可具有不對稱中心,且因此以不同鏡像異構體形式存在。通式化合物之所有光學異構體及立體異構體及其混合物視為在該式之範疇內。因此,本文所給出之任何式意欲代表外消旋物、一或多種鏡像異構體形式、一或多種非鏡像異構體形式、一或多種阻轉異構體形式及其混合物。此外,某些結構可以幾何異構體(即順式及反式異構體)、互變異構體或阻轉異構體形式存在。
使用符號與意指本文所顯示化學結構之相同空間排列。類似地,使用符號與意指本文所顯示化學結構之相同空間排列。
如本文所使用,「化合物」係指以下中之任一者:(a)該化合物之實際列出形式;及(b)在命名時該化合物在所考慮之該化合物於其中之介質中之任一形式。例如,本文對化合物例如R-COOH之提及涵蓋對例如R-COOH(s)、R-COOH(sol)及R-COO-(sol)中任一者之提及。
在此實例中,R-COOH(s)係指固體化合物,如其可呈例如錠劑或一些其他固體醫藥組合物或製劑形式;R-COOH(sol)係指化合物於溶劑中之未解離形式;且R-COO-(sol)係指化合物於溶劑中之解離形式,例如化合物於水性環境中之解離形式,無論該解離形式係衍生自R-COOH、其鹽抑或在所考慮介質中解離後產生R-COO-之任何其他實體。
如本文所使用,術語「化學實體」統指化合物以及該化合物之衍生物,包含鹽、螯合物、溶劑合物、構型異構物、非共價複合物、代謝物及前藥。
在一態樣中,化學實體係選自由以下組成之群:式(I)化合物、式(I)化合物之醫藥上可接受之鹽、式(I)化合物之醫藥上可接受之前藥及式(I)化合物之醫藥上可接受之代謝物。
在另一實例中,諸如「實體於式R-COOH化合物下之暴露」之表述係指該實體於化合物R-COOH之存在於發生該暴露之介質中之形式下的暴露。在另一實例中,諸如「使實體與式R-COOH化合物反應」之表述係指使(a)呈該實體之存在於發生該反應之介質中之化學相關形式之該實體與(b)化合物R-COOH之存在於發生該反應之介質中之化學相關形式反應。就此而言,若該實體係在例如水性環境中,則應理解化合物R-COOH係在該同一介質中,且因此該實體暴露於諸如R-COOH(aq)及/或R-COO-(aq)等物質下,其中下標「(aq)」根據其在化學及生物化學中之習用含義代表「水溶液」。在該等命名實例中已選擇羧酸官能基;然而,此選擇並不意欲具有限制性而僅具有闡釋性。應理解,類似實例可以其他官能基來提供,包含(但不限於)羥基、鹼性氮成員(例如彼等於胺中者)及根據已知方式在含有該化合物之介質中相互作用或轉變之任何其他基團。該等相互作用及轉變包含(但不限於)解離、締合、互變異構、溶解分解(包含水解)、溶劑化(包含水
合、質子化及去質子化)。本文在此方面不再提供其他實例,此乃因任一熟習此項技術者已知給定介質中之該等相互作用及轉變。
在另一實例中,本文藉由提及已知形成兩性離子之化合物涵蓋「兩性離子」化合物,即使其並未以其兩性離子形式明確命名。諸如兩性離子及其同義詞兩性離子化合物等術語係熟知且為所定義科學名稱之標準集合之一部分的經IUPAC認可之標準名稱。就此而言,藉助分子實體之生物相關化學實體(Chemical Entities of Biological Interest,ChEBI)詞典為名稱兩性離子指配名稱識別符CHEBI:27369。如業內通常熟知,兩性離子或兩性離子化合物係具有異號形式單位電荷之中性化合物。有時該等化合物藉由術語「內鹽」來提及。其他來源係指呈「偶極離子」形式之該等化合物,但後一術語因其他來源而視為誤稱。作為特定實例,胺基乙酸(胺基酸甘胺酸)具有式H2NCH2COOH,且其係以兩性離子+H3NCH2COO-形式存在於一些介質中(在此情形下存在於中性介質中)。在該等術語之已知且充分確立之含義中之兩性離子、兩性離子化合物、內鹽及偶極離子係在本發明範疇內,如將在任何情形下為彼等熟習此項技術者所瞭解。由於不需要命名將為彼等熟習此項技術者所意識到之每個實施例,故本文未明確給出與本發明化合物相關之兩性離子化合物之結構。然而,其係本發明實施例之一部分。本文在此方面不再提供其他實例,此乃因任一熟習此項技術者已知在給定介質中產生給定化合物之各種形式之相互作用及轉變。
同位素可存在於所闡述化合物中。存在於本文所特別地或一般地闡述之化合物中之每一化學元素可包含該元素之任何同位素。本文所給出之任一式亦欲代表化合物之未經標記形式以及經同位素標記之形式。經同位素標記之化合物具有由本文所給出式繪示之結構,只是由具有所選原子質量或質量數之原子替代一或多個原子。可納入本發
明化合物中之同位素之實例包含氫、碳、氮、氧、磷、氟、硫、氟、氯及碘之同位素,例如分別為2H、3H、11C、13C、14C、15N、18O、17O、31P、32P、35S、18F、36Cl、125I。
在提及本文所給出之任何式時,為指定變量自可能種類之列表選擇具體部分並不意欲為別處出現之變量定義種類之相同選擇。換言之,除非另有說明,否則當變量出現一次以上時,自指定列表選擇種類獨立於為式中別處之相同變量選擇種類。

本文所提及之任何二取代基當允許一種以上之附接可能性時意欲涵蓋眾多該等可能性。例如,對二取代基-A-B-(其中A≠B)之提及在本文中係指A附接至第一經取代成員且B附接至第二經取代成員之該二取代基,且其亦指A附接至第二成員且B附接至第一經取代成員之該二取代基。
根據對指配及命名之前述說明性考慮,應理解,倘若在化學上有意義且除非另外指明,否則本文對集合之明確提及暗示對該集合實施例之獨立提及以及對明確提及之該集合子集之每一可能實施例之提及。
術語「前藥」意指指定化合物在投與個體後經由化學或生理學過程(例如溶解分解或酶促裂解)或在生理學條件(例如,前藥在生理學pH下轉化成式(I)化合物)下在活體內產生化合物之前驅物。

在一態樣中,本發明化合物可用於增強可在健康動物中加強且可在多種CNS病症中受損之神經元可塑性(腦之基本性質)。例如,藉由抑制PDE4,本發明化合物可增加cAMP之含量,從而調節環狀核苷酸信號傳導級聯。
更具體而言,細胞外信號調節細胞內環狀核苷酸濃度之能力允許細胞越過細胞膜邊界因應外部刺激物。環狀核苷酸信號傳導級聯已
適用於因應許多轉導系統,包含G蛋白偶合受體(GPCR)以及電位及配體門控離子通道。環狀核苷酸將其細胞中之信號傳送通過眾多種三級元件。該等元件中之最佳闡述者係cAMP依賴性蛋白激酶(PKA)及cGMP依賴性蛋白激酶(PKG)。環狀核苷酸至每一酶之結合使得能夠磷酸化在信號傳導級聯中用作效應子或其他元件之下游酶及蛋白質。對記憶形成尤其重要者係PKA之cAMP依賴性活化,其使CREB磷酸化。pCREB係經活化之轉錄因子,其結合至特定DNA座且起始多種參與神經元可塑性之基因之轉錄(例如,Tully等人,Nat.Rev.Drug.Discov.2003,2,267-277;及Alberini,Physiol.Rev.2009,89,121-145)。
與該等觀察一致,活體外及活體內研究二者皆已將環狀核苷酸濃度之變化與認知功能連接之生物化學及生理學過程相關聯(Kelly及Brandon,Progress in Brain Research,2009,179,67-73;Schmidt,Current Topics in Medicinal Chemistry,2010,10,222-230)。此外,業內已確立突觸處之信號強度及同步活動之程度可變化,此可使具體突觸處之傳送增效。長期增效(LTP)係該等過程中之最佳闡述者且已知由cAMP及cGMP信號傳導級聯二者來調節。

在特定態樣中,運動障礙亦包含多發性硬化症、基底神經節病
症、運動減退及運動困難。
在一實施例中,本發明提供治療路易氏體病之方法,其包括向需要該治療之動物投與有效量之本發明化合物或組合物。路易氏體係以置換其他細胞組份之球粒出現。兩種形態類型為經典(腦幹)路易氏體及皮質路易氏體。經典路易氏體係由10nm寬之輻射纖維環圍繞之緻密核心組成之嗜伊紅細胞質內含物,其主要結構組份係α-突觸核蛋白。相比之下,皮質路易氏體之定義較不明確且缺少環。無論如何,其仍係由α-突觸核蛋白纖維構成。皮質路易氏體係路易氏體癡呆(DLB)之區別性特徵,但偶爾可見於匹克病(Pick's disease)及皮質基底核退化特有之氣球樣神經元以及患有其他τ蛋白病之患者中。
更具體而言,路易氏體病症係選自由以下組成之群:多系統萎縮症,尤其帕金森氏症變體;不具或具癡呆之帕金森氏病(PDD);單獨或與阿茲海默氏病(AD)締合之LB癡呆(DLB);多系統萎縮症,尤其帕金森氏症變體,以及匹克病及皮質基底核退化。
在一實施例中,本發明提供治療與多發性硬化症(MS)相關之運動症狀之方法,其包括向需要該治療之動物投與有效量之本發明化合物或組合物。MS係侵襲CNS之腦及脊髓之自體免疫性、脫髓鞘性疾病。其侵襲女性多於男性且最常在20歲與40歲之間被診斷出,但可見於任何年齡。
MS係因髓鞘(圍繞神經細胞之保護性覆蓋)損傷而引起。當此神經覆蓋受損時,神經信號減緩或終止。由於腦或脊髓之任何部分中之神經皆可能受損,故患有多發性硬化症之患者可在身體之許多部分中具有症狀。症狀因每次發作之位置及嚴重程度可不同而有所變化。發作可持續數天、數週或數月。該等發作與減少的或無症狀(緩解)之時
段交替。
與MS相關之肌肉症狀包含平衡喪失;肌肉痙攣;任何區域之麻木、麻刺或異常感覺;移動臂或腿之問題;步行問題;協調及進行小型運動之問題;一或多個臂或腿之震顫;及一或多個臂或腿之無力。
在具體實施例中,本發明提供治療基底神經節病症之方法。基底神經節病症係指當腦中之核群(稱為基底神經節)無法適當地阻抑不期望運動或無法適當地引發向上運動神經元迴路來起始運動功能時發生的物理功能障礙之群(Leisman及Mello,Rev.Neurosci.2013,24,9-25)。
基底神經節之增加的輸出抑制丘腦皮質投射神經元。該等神經元之適當活化或去活化係適當運動不可缺少之組份。若有時導致過多基底神經節輸出,則丘腦皮質投射神經元變得更受抑制且無法起始有意運動。該等病症稱為 運動不足 症。然而,導致基底神經節異常低之輸出之病症相對並不抑制丘腦皮質投射神經元。此情況導致無法阻抑不期望運動。該等病症稱為 過動 症(Wichmann及DeLong,Curr.Opin.Neurobiol 1996,6,751-758)。
在具體實施例中,本發明提供治療運動減退之方法。運動減退係指身體運動減少,且其尤其可能與基底神經節疾病(例如帕金森氏病)、心智健康病症及疾病所致之長時間不活動相關。
更通常而言,運動減退闡述一系列病症,包含:(i)失動症,其係指因難以選擇或活化中樞神經系統中之運動程式而無法起始運動。失動症係直接運動途徑中多巴胺能細胞活性嚴重降低之結果且常見於帕金森氏病之重度病例中;(ii)運動徐緩,其特徵在於運動緩慢且與帕金森氏病及其他基底神經節病症相關。運動徐緩闡述運動執行緩慢
而非起始緩慢(失動症)。其係帕金森氏症之3種關鍵症狀運動徐緩、震顫及僵硬中之一者。運動徐緩亦係在患有帕金森氏症之彼等中通常稱為「面無表情」(毫無表情)者之原因;(iii)呆滯,其特徵在於無法在任何期望方向上移動肌肉;及(iv)僵硬,其特徵在於肌肉張力增加,從而抵抗外部施加之關節運動;及(v)姿勢不穩,其喪失維持直立姿勢之能力。
在具體實施例中,本發明提供治療運動困難之方法。運動困難係由包含減少的有意運動及存在類似於抽動或舞蹈症之無意運動之不利效應組成的運動障礙。
運動困難可係來自手對最常見上身之不受控運動之輕微震顫之任何事項但亦可見於下肢中。失協調亦可發生在尤其具有呼吸肌之內部且其通常無法識別。運動困難係根本原因不同且通常對應於以下三種類型中之一者之若干醫學病症之症狀:急性運動困難、慢性(或遲延)運動困難及非運動運動困難。
更特定而言,運動困難可包含以下中之一或多者:陣發性運動困難,例如原發性及繼發性陣發性運動困難;陣發性誘發性運動困難(PKD);陣發性非誘發性運動困難(PNKD);陣發性鍛煉誘發型(用力誘發型)運動困難(PED);及陣發性睡眠誘發性運動困難(PHD)。
在特定實施例中,本發明提供治療創傷相關病症之方法,其包括向需要該治療之動物投與有效量之本發明化合物或醫藥組合物。
在特定實施例中,創傷相關病症包括腦創傷;頭部創傷(閉合性及穿透性);頭部損傷;腫瘤,尤其侵襲丘腦之大腦腫瘤或顳葉頭部損傷;腦血管病症(侵襲腦血管之疾病),例如中風、缺血、低氧及病毒感染(例如,腦炎);興奮性中毒;及癲癇。
在本發明範疇內適於神經保護之病況包含:中風;創傷性腦損傷(TB);癡呆;阿茲海默氏病;帕金森氏病;亨廷頓氏病;大腦性麻痺;小兒麻痺後症候群;格林-巴利症候群(Guillain-Barre syndrome)及多發性硬化症;及其他發展症候群、遺傳病及侵襲認知功能之進行性CNS疾病,例如自閉症譜系障礙、胎兒酒精譜系障礙(FASD)、魯塔二氏症候群(Rubinstein-Taybi syndrome)、唐氏症候群(Down syndrome)及其他形式之心智遲滯。
在特定實施例中,本發明提供治療疼痛之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。在文獻中已知PDE4抑制劑治療疼痛之效用。
在具體實施例中,疼痛病症包含以下中之一或多者:牙痛、癌症疼痛、肌筋膜疼痛、圍術期疼痛、急性疼痛、慢性疼痛、創傷後疼痛、三叉神經痛、重度偏頭痛、頑固性疼痛、神經病變疼痛、創傷後疼痛、癌症疼痛、非癌症疼痛。疼痛亦涵蓋與心理因素相關之疼痛病症、與一般醫學病況相關之疼痛病症及與心理因素及一般醫學病況二者相關之疼痛病症。
在本發明之具體實施例中,神經病症為認知障礙。因此,本發明提供治療認知障礙之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。在文獻中已知PDE4抑制劑治療認知障礙之效用(例如,美國專利第US 7,829,713號;美國專利第US8,338,405號)。
認知障礙可嚴重損害社交及職業功能,對受侵襲個體之自主性及生活品質造成不利影響。估計4至5百萬美國人(所有年齡之約2%及彼等65歲以上者之15%)具有一定形式及程度之認知損害(Abrams等
人,Merck Manual of Geriatrics,1995,Whitehouse Station(NJ),Medical Services)。
認知障礙反映認知方面(即獲取、保留及利用知識之一般過程)之問題。因此,認知障礙可涵蓋諸如集中力、感知、注意力、資訊處理、學習、記憶或語言等功能之損害。認知障礙亦可涵蓋精神性運動學習能力之損害,該等能力包含物理技能,例如運動及協調;精細運動技能,例如使用精密儀器或工具;及大肌肉運動技能,例如舞蹈、音樂或體育效能。
認知障礙亦涵蓋執行功能之損害,該等功能包含計劃及執行目標定向行為之基礎能力。該等能力包含靈活性,即快速切換至適宜心智模式之能力;基於圖案識別之預見及預測;推理及解決問題;做決策;工作記憶,即實時掌握及操縱內源及外源性資訊之能力;情感自我調控,包含識別及管控情感以展現良好效能之能力;排序,例如將複雜動作解剖成可管控單元且將其按正確順序優先排序之能力;及自我抑制,即經受分心及內部衝動之能力。
認知障礙亦包括與(歸因於)CNS病症相關之認知損害(缺陷或功能障礙)。在一態樣中,認知損害可係CNS病症之直接結果。例如,言語及語言損害可直接源自中風或損傷控制言語及語言之腦區(如失語症)之頭部損傷。
在另一態樣中,認知損害與複雜的CNS病症、病況或疾病相關。例如,認知損害可包括伴有自閉症或心智遲滯之執行控制缺陷;與精神分裂症或帕金森氏病相關之記憶缺陷;或源自多發性硬化症之認知缺陷。在多發性硬化症(MS)之情形下,例如約一半的MS患者將經歷認知功能問題,例如思考減緩、集中力下降或記憶受損。該等問題通常發生在MS病程之後期,但在一些情形下可更早發生(若非在疾病發作時)。
認知損害可歸因於許多非排他性類別之CNS病症,包含以下各項(及如本文所闡述者):
(1)癡呆,例如與阿茲海默氏病、帕金森氏病、亨廷頓氏病、匹克病、庫賈氏病(Creutzfeldt-Jakob)、AIDS癡呆及其他神經退化性病症相關之彼等;及與涉及神經系統之進行性疾病(例如多發性硬化症)相關之認知能力喪失。
(2)精神病學病症,其包含情感(情緒)病症,例如抑鬱症及雙向情感病症;精神病症,例如精神分裂症及妄想症;及神經質及焦慮症,例如恐懼症、恐慌症、強迫症、廣泛性焦慮症;飲食病症;及創傷後壓力病症。
(3)發展症候群、遺傳病及侵襲認知功能之進行性CNS疾病,例如自閉症譜系障礙;胎兒酒精譜系障礙(FASD);魯塔二氏症候群;唐氏症候群及其他形式之心智遲滯;及多發性硬化症。
(4)創傷依賴性認知功能喪失,即源自腦創傷、頭部創傷(閉合性及穿透性)之記憶、語言或運動技能損害;頭部損傷;腫瘤,尤其侵襲丘腦或顳葉之大腦腫瘤;腦血管病症(侵襲腦血管之疾病),例如中風、缺血、低氧及病毒感染(例如,腦炎);興奮性中毒;及癲癇。該等創傷依賴性喪失亦涵蓋源自諸如以下等外在因素之認知損害:酒精使用、長期藥物使用及神經毒素(例如鉛、汞、一氧化碳及某些殺昆蟲劑)(例如,Duncan等人,Drug Discover.Ther.2012,6,112-122)。
(5)年齡相關性認知缺陷,包含年齡相關性記憶損害(AAMI;在本文中亦稱為年齡有關記憶損害(AMI))及侵襲認知下降早期(如輕度認知損害(MCI))患者之缺陷;及
(6)學習、語言或閱讀能力喪失,例如感知障礙、失讀症及注意力缺陷病症。
因此,本發明提供治療與選自包括以下之群中之一或多者的CNS病症相關之認知損害之方法:癡呆,包含與神經退化性病症相關之彼等;精神病學病症;發展症候群、遺傳病以及進行性CNS疾病及遺傳病;創傷依賴性認知功能喪失、年齡相關性認知缺陷;及學習、語言或閱讀病症。
在特定實施例中,本發明提供治療與癡呆相關之認知缺陷之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。
癡呆係特徵在於學習及認知缺陷之神經退化性疾病且通常伴有行為症狀、心理症狀及運動症狀。更具體而言,癡呆症狀可包含許多心智功能區域困難,包含感情型行為或人格、語言、記憶、感知及思考以及判斷。
癡呆包含(但不限於)以下各項:阿茲海默氏病(具有早期或晚期發作)所致之癡呆、帕金森氏病所致之癡呆、匹克病所致之癡呆、庫賈氏病所致之癡呆、HIV疾病所致之癡呆、頭部創傷所致之癡呆;血管性疾病所致之癡呆(「血管性癡呆」)、路易氏體癡呆、額顳葉癡呆、匹克病及皮質基底核退化。
在一實施例中,癡呆歸因於阿茲海默氏病。因此,本發明提供治療阿茲海默氏病所致之癡呆之方法,其包括向需要該治療之動物投與治療有效量之本文所闡述之化合物或醫藥組合物。在文獻中已知PDE4抑制劑治療阿茲海默氏病之效用。因此,本發明提供治療阿茲海默氏病所致之癡呆之方法,其包括向需要該治療之動物投與治療有效量之本文所闡述之化合物或醫藥組合物。
在另一實施例中,癡呆歸因於帕金森氏病。因此,本發明提供治療帕金森氏病所致之癡呆之方法,其包括向需要該治療之動物投與
治療有效量之本文所闡述之化合物或醫藥組合物。據報導,癡呆發生在大約20%-60%之患有帕金森氏病之個體中,且更可能存在於老年個體或彼等患有更嚴重或晚期疾病之個體中。與帕金森氏病相關之癡呆之特徵在於,認知及運動減緩;執行功能問題,例如計劃作業、組織項目或以適當序列實施目標;及記憶檢索損害。患有帕金森氏病之個體之認知效能下降通常因抑鬱症而加重。在文獻中已知PDE4抑制劑治療帕金森氏病之效用。
據報導,癡呆發生在大約20%-60%之患有帕金森氏病之個體中,且更可能存在於老年個體或彼等患有更嚴重或晚期疾病之個體中。與帕金森氏病相關之癡呆之特徵在於認知及運動減緩、執行功能障礙及記憶檢索損害。患有帕金森氏病之個體之認知效能下降通常因抑鬱症而加重。參見綜述Davie,Br.Med.Bull.2008,86,109-127。帕金森氏病之運動症狀源自黑質(中腦區域)中產生多巴胺之細胞之死亡;此細胞死亡之原因未知。在該疾病病程之早期,最明顯症狀與運動相關。將四種運動症狀視為PD之主要症狀:搖晃(震顫)、僵硬、運動緩慢及姿勢不穩,即步行及步態困難(例如,Jankovic,J.Neurol.Neurosurg.Psychiatr.2008,79,368-376)。隨後,可產生認知及行為問題,且癡呆通常發生在疾病晚期。其他症狀包含感覺、睡眠及感情問題。PD在老人中更為常見,且大多數病例發生在50歲之後。
在另一態樣中,認知損害與複雜的CNS症候群、病況或疾病相關。例如,認知損害可包括伴有自閉症或心智遲滯之執行控制缺陷;與精神分裂症或帕金森氏病相關之記憶缺陷;或源自多發性硬化症之認知缺陷。在多發性硬化症(MS)之情形下,例如約一半的MS患者將經歷認知功能問題,例如思考減緩、集中力下降或記憶受損。該等問題通常發生在MS病程之後期,但在一些情形下若非處於疾病發作時,其可更早發生。
在一態樣中,認知損害可係CNS病症之直接結果。例如,言語及語言損害可直接源自中風或損傷控制言語及語言之腦區(如失語症)之頭部損傷。
在特定實施例中,本發明提供治療與精神病學病症相關之認知缺陷之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。精神病學病症包含情感病症(情緒病症),例如抑鬱症及雙向情感病症;精神病症,例如精神分裂症及妄想症;及神經質及焦慮症,例如恐懼症、恐慌症、強迫症、廣泛性焦慮症、飲食病症及創傷後壓力病症。
在特定實施例中,本發明提供治療與發展症候群、遺傳病或進行性疾病相關之認知缺陷之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。在特定態樣中,認知缺陷與以下疾病相關:自閉症譜系障礙;胎兒酒精譜系障礙(FASD);魯塔二氏症候群;唐氏症候群及其他形式之心智遲滯;及多發性硬化症。
在特定實施例中,本發明提供治療與創傷相關之認知缺陷之方法。該等創傷依賴性認知功能喪失包含(但不限於)腦血管疾病(包含中風及缺血)所致之彼等;腦創傷,包含硬膜下血腫及腦腫瘤;創傷性腦損傷(TBI)及頭部損傷。
該等創傷依賴性喪失亦涵蓋源自諸如以下等外在因素之認知損害:酒精使用、長期藥物使用及神經毒素(例如鉛、汞、一氧化碳及某些殺昆蟲劑)。
在一些實施例中,本發明之化學實體及組合物可用於治療中風,且在更特定實施例中,治療中風後復健期間之運動或認知損害。中風護理係包含立即(急性)治療及後續復健療法之時間連續體。
急性治療直接靶向初始損傷,例如由缺血性或出血性中風觸發者;其通常涉及使用溶解凝塊且復原血流之藥劑來減少組織損傷並穩定患者。急性治療之功效通常受限於自中風發作延伸僅幾小時之短時間窗口。
復健變成患者在醫學上穩定後之治療焦點。復健(亦稱為「中風復健」或「中風後復健」)係針對在初始中風損傷後存留之認知及運動缺陷,目標在於儘可能地復原及恢復神經功能以補償永久性組織喪失。(例如,1995 Clinical Guideline by the Department of Health and Human Services on Post-Stroke Rehabilitation。)
中風復健通常係由一隊醫務人員協調之綜合性程式。該隊中之物理治療師例如可致力於維持並復原受侵襲肢體之運動範圍及強度,從而使步行活動性最大化,改善手工熟練度並使其他運動及感覺運動功能復健。心智衛生專業人員可參與治療認知技能喪失。復健服務可在多種環境下進行,例如復健醫烷、長期護理設施、門診或在家。
受中風影響(且可在復健期間靶向)之神經功能包含認知及運動功能損害。認知功能損害例如可表現為言語理解或書寫缺陷(失語症);瞭解所說的話但難以清楚地將其講出(口吃);以及其他認知功能缺陷,例如注意力、推理、計劃、執行以及學習及記憶。運動功能損害例如可表現為可侵襲整側或僅臂或腿之身體一側無力(半身輕癱)或麻痺(半身不遂);平衡或協調問題;大肌肉運動技能缺陷,例如步態及步行速度;精細運動技能或手工熟練度缺陷;及上肢及下肢功能缺陷。
因此,本發明提供PDE4抑制劑在治療中風方面之用途,其包含
中風後復健之方法。在某些實施例中,本發明之化學實體可在中風復健期間用於治療源自神經功能受損之中風缺陷(或「中風後缺陷」)。在一些實施例中,本發明提供中風後復健之方法,其包括:(a)在個體自中風恢復期間,向有需要之個體投與PDE4抑制劑;(b)在足以改善損害係由該中風所致之神經功能之效能條件下向個體提供訓練;及(c)重複步驟(a)及(b)一或多次,藉此相對於僅由訓練所達成之改善效能,可以減少足以改善該效能之訓練量。
在一態樣中,PDE4抑制劑係本發明之化學實體。在一些實施例中,缺陷為運動缺陷。在其他實施例中,缺陷為認知缺陷,尤其記憶形成缺陷,且更特定而言長期記憶形成缺陷。在其他實施例中,缺陷可包含認知及運動缺陷。在另一態樣中,訓練包括一系列針對神經功能之作業。在特定態樣中,訓練量之減少係訓練期數之減少。
在另一實施例中,一或多個訓練步驟係由離散間隔隔開。在一態樣中,每天提供每一訓練步驟。在其他態樣中,一或多個訓練步驟之間之間隔可小於一天或大於一天,例如每週一次、每週兩次、每週三次或更長。
在另一實施例中,將該投與步驟(a)與該訓練步驟(b)結合。在一態樣中,個體為人類。在另一態樣中,個體已經受神經元幹細胞操縱。在其他態樣中,化合物係在每一訓練期之前及期間投與。
在特定實施例中,本發明提供治療年齡相關性認知缺陷之方法。在一態樣中,年齡相關性認知缺陷係年齡有關記憶損害(AAMI)。因此,本發明提供治療年齡相關性記憶損害(AAMI)之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。
AAMI係與正常衰老相關之眾多種認知能力、尤其記憶能力之下降。例如,AAMI個體顯示編碼事件或事實之新記憶以及工作記憶之能力下降(Hedden及Gabrieli,Nat.Rev.Neurosci.2004,5,87-96)。此外,在與額葉功能相關之執行功能測試中,AAMI個體當與年齡匹配之對照相比時似乎受損。該等及其他研究表明額葉功能障礙在老年人之記憶喪失方面之重要作用。更通常而言,比較衰老對情景記憶、語意記憶、短期記憶及啟動之效應之研究發現情景記憶在正常衰老中尤其受損;但一些類型之短期記憶亦可受損(Nilsson,Acta Neurol.Scand.Suppl.2003,179,7-13)
通常,AAMI診斷鑒定出患有主觀及客觀證實之記憶喪失但認知下降尚未受損至足以保證診斷出癡呆之個人。根據NIH工作組確立之標準(Crook等人,Devel.Neuropsychol.1986,2,261-276),AAMI之診斷在50歲或以上之人中包含以下各項:(i)存在主觀記憶下降,例如,記憶喪失之陳情在該等日常問題中反映為難以記住向該個體介紹之個體之姓名,誤放目標,難以記住欲購買物品之列表或欲實施作業之列表;(ii)記憶喪失之客觀證據(例如,在良好標準化之記憶測試中評分比年輕人平均值低至少一個標準偏差);(iii)在魏氏成人智力量表(Wechsler Adult Intelligence Scale)之詞彙子測試中之足夠智力功能之證據(例如,原始評分為至少32),及(iv)不存在癡呆(或其他侵襲記憶之疾病,例如中風),例如基於全面衰退量表(Global Deterioration Scale)來評估癡呆,患有AAMI之個體具有極輕度認知下降(2級)(Reisberg等人,Am.J.Psych.1982,139,1136-1139)。
已顯示,患有AAMI之個體罹患癡呆之風險係不滿足AAMI標準之個體的3倍(Goldman及Morris,Alzheimer Dis.Assoc.Disord.2002,
15:72-79)。
在特定實施例中,本發明提供治療輕度認知損害(MCI)之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。
MCI可在個體之記憶下降至對該年齡群體視為正常之水準以下時被診斷出。換言之,MCI係其中個人面對記憶問題比其年齡之普通人更頻繁之病況。然而,該等症狀並不妨礙其實施正常活動,且並不如阿茲海默氏病之症狀嚴重。症狀通常包含誤放物品、忘記事件或預約且難以思考想說的話。
根據最新研究,將MCI稱為正常衰老與阿茲海默氏病(AD)之間之認知改變之過渡狀態。許多經歷輕度認知損害之人具有罹患阿茲海默氏病之高風險。實際上,研究表明:約12%之65歲或以上經診斷患有MCI之人在一年內罹患阿茲海默氏病;且約40%在三年內罹患阿茲海默氏病。此速率遠高於一般人群,其中每年僅約1%之65歲或以上之人罹患阿茲海默氏病。
因此,業內認為患有MCI之人具有罹患阿茲海默氏病之更高風險。然而,該等症狀並不妨礙其實施正常活動,且並不如阿茲海默氏病之症狀嚴重。症狀通常包含誤放物品、忘記事件或預約且難以思考想說的話(例如,Arnáiz及Almkvist,Acta Neurol.Scand.Suppl.2003,179,34-41)。然而,一些患有MCI患者從未進展成AD。
在特定實施例中,本發明提供治療學習、語言或閱讀能力喪失之方法,其包括向需要該治療之動物投與有效量之本文所闡述之化合物或醫藥組合物。
在特定實施例中,本發明提供神經保護之方法,其包括向有需要之動物投與有效量之本發明化學實體或組合物。
與神經可塑性一樣,神經保護反映為神經系統保護之中心之內源神經生物學過程。。更特定而言,神經保護係指停止或減緩神經元喪失、由此預防或減緩疾病進展及二級損傷之能力。在具體態樣中,神經保護靶向源自氧化應力及興奮性中毒之神經元損傷,氧化應力及興奮性中毒二者皆與CNS病症高度相關,但症狀或損傷不同。
在文獻中已知PDE4抑制劑治療神經元損傷之效用。除神經退化性疾病外,神經元損傷亦可源自創傷之其他來源,例如腦血管疾病,包含中風及缺血;腦創傷,包含硬膜下血腫及腦腫瘤;及頭部損傷。
在某些實施例中,使用本文之化合物或組合物作為增強認知或運動訓練(統稱為「訓練」)效率之方法中之加強劑。該等增強方法統稱為「加強訓練」,其包括「增強認知訓練」或「增強運動訓練」。
訓練通常需要多期來獲得期望益處,例如復健中風後之運動缺陷或語言缺陷。此可成本高且耗時,從而阻止個體順從且實現隨時間持續之現實世界益處。該等訓練方案之效率可藉由結合訓練方案投與某些藥劑(已知作為加強劑)來改善(例如,U.S.7,868,015;U.S.7,947,731;US 2008-0188525)。加強訓練包括具體腦功能(例如潛在陳述性記憶、精細運動技能之效能、移行、語言獲取、執行功能等)之特定訓練方案及增強CREB途徑之藥物之一般投與。該訓練方案(認知或運動訓練)誘導特定腦區之神經元活性且產生特定腦(認知或運動)功能經改善之效能。換言之,使用加強劑利用較少重複(即較少訓練期)即達成認知訓練效應。
在一些實施例中,本發明提供治療認知障礙之方法,且更具體而言改善與動物之中樞神經系統(CNS)病症或病況相關之認知缺陷的
方法,其包括使用增強CREB途徑功能之加強劑結合認知訓練來治療動物,其中該增強劑係本發明化合物或組合物。例如已顯示,本發明之實例性化合物在基於細胞之分析中使CREB活化。
在一態樣中,該方法包括:(a)在足以使該動物之與認知缺陷相關之認知功能損害達成改善效能的條件下,向需要治療該認知缺陷之個體提供認知訓練;(b)在結合該認知訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由認知訓練所達成之改善效能,可以減少足以達成相同改善效能時之訓練期數。
在另一態樣中,該方法包括:(a)在足以使該動物之與認知缺陷相關之認知功能損害達成改善效能的條件下,向需要治療該認知缺陷之個體提供認知訓練;(b)在結合該認知訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由認知訓練所達成之改善該功能效能,可以達成長期改善該功能效能。
在一態樣中,本發明化合物或組合物可作為加強劑與意欲調節腦認知功能之任何心理治療方式結合使用,由此藉由減少獲得益處所需之期數來增強該療法之功效。
在另一態樣中,藉由該等方法治療之認知缺陷為或包含記憶損害,且更尤其長期記憶缺損。長期記憶(LTM)通常包括兩種主要生物性質。第一,形成長期記憶需要合成新蛋白質。第二,其涉及cAMP反應性轉錄,且經由cAMP反應元件結合蛋白(CREB)家族轉錄因子來調介。本發明化合物可用作CREB加強劑,且因此可用於增強動物之記憶形成,且更具體而言轉錄依賴性記憶形成。實際上,本發明之實例性化合物在基於細胞之分析中使CREB活化。
在一些實施例中,本發明提供治療運動障礙之方法,且更具體而言改善動物之與中樞神經系統(CNS)病症或病況相關之運動缺陷的
方法,其包括使用增強CREB途徑功能之加強劑結合運動訓練來治療動物。本文亦提供在需要該治療之動物中提供與中樞神經系統(CNS)病症或病況相關之運動缺陷之持續改善的方法,其包括向該動物投與本發明化合物或組合物;及檢測該持續改善。
在一態樣中,該方法包括:(a)在足以使該動物之與認知缺陷相關之運動功能損害達成改善效能的條件下,向需要治療該運動缺陷之個體提供運動訓練;(b)在結合該運動訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由運動訓練所達成之改善效能,可以減少足以達成相同改善效能時之訓練期數。
在另一態樣中,該方法包括:(a)在足以使該動物之與認知缺陷相關之運動功能損害達成改善效能的條件下,向需要治療該運動缺陷之個體提供運動訓練;(b)在結合該運動訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由運動訓練所達成之改善該功能效能,可以達成長期改善該功能效能。
在其他實施例中,本發明提供增強原本健康之動物(尤其人類或其他哺乳動物或脊椎動物)之認知效能之特定態樣的方法,其包括(a)向該動物投與本發明之加強劑;及(b)在足以使該動物產生具體認知作業效能改善的條件下訓練該動物。在其他實施例中,本發明提供增強認知或運動效能之方法以及重複刺激例如為特定神經元迴路基礎之神經元活動或神經元活動模式之方法。
加強劑(包含本文之化合物及組合物)能夠增強CREB途徑功能。相對於僅藉由訓練觀察到之改善,藉由結合訓練增強CREB途徑功能,該加強的訓練可減少改善認知或運動功能之效能所需之訓練期數(例如,U.S.2007-0203154、U.S.2011-0160248、U.S.2010-0317648
及美國專利第8,222,243號)。
加強劑可在一或多個訓練期之前、期間或之後投與在具體實施例中,加強劑係在每一訓練期之前及期間投與。加強劑結合每一訓練期之治療係亦稱為「加強治療」。
訓練方案通常用於患有一定形式及程度之認知或運動功能障礙之復健個體中。例如,訓練方案通常用於中風復健及年齡有關記憶喪失復健中。由於在個體中獲得認知(或運動)效能(能力或功能)之特定態樣之改善或增強前通常需要多個訓練期,故訓練方案通常成本極高且耗時。加強訓練方法更有效且因此更加成本有效。
例如,人類腦損傷通常引起運動及認知損害。儘管危象護理醫學及患者管控之進步已改善創傷性腦損傷(TBI)後之患者結果,但當前業內仍無已知預防TBI後神經元細胞死亡及功能障礙之治療。儘管多種治療已在TBI臨床前模型中證明具有神經保護作用,但大多數並未顯示在人類中之功效。
一旦患者在TBI後穩定,標準護理即指示大量運動或認知復健。在此復健期間,患者通常複得所喪失之技能,最終產生經改善之功能結果。若醫藥治療可經研發以增強TBI後之運動或認知復健且因此改善功能結果時有益。
認知及運動訓練方案以及基本原理為業內所熟知(例如,Allen等人,Parkinsons Dis.2012,1-15;Jaeggi等人,Proc.Natl.Acad.Sci.USA 2011,108,10081-10086;Chein等人,Psychon.Bull.Rev.2010,17,193-199;Klingberg,Trends Cogn.Sci.2010,14,317-324;Owen等人,Nature 2010,465,775-778;Tsao等人,J.Pain 2010,11,1120-1128;Lustig等人,Neuropsychol.Rev.2009,19,504-522;Park及Reuter-Lorenz,Ann.Rev.Psych.2009,60,173-196;Oujamaa等人,

在一些實施例中,可使用該等方案來治療或復健患病個體之認知或運動損害。該等方案可具有復原性或補救性,意欲重新確立先前技能及功能,或其可致力於延遲或減緩神經疾病所致之認知或運動下降。其他方案可具有補償性,以藉由增強相關及不相關腦結構域之功能提供適用於認知或運動缺陷之方式。在其他實施例中,可使用該等方案來改善原本健康個體之具體技能或認知或運動功能。例如,認知訓練程式可包含致力於延遲或預防通常伴有衰老之認知下降之模組;
此處該程式經設計以維持或改善認知健康。
通常,訓練方案(或模組)包括一組可具有過程特異性或基於技能之不同鍛煉:過程特異性訓練致力於改善諸如注意力、記憶、語言、執行功能或運動功能等具體結構域。在此處,訓練之目標係獲得自所訓練活動轉移至與相同的認知或運動功能或結構域相關之未經訓練活動之一般改善。例如,可使用聽覺認知訓練方案來治療聽覺注意力受損之學生。在訓練結束時,該學生應顯示聽覺注意力之廣泛性改善,表現為注意且專注於課堂所呈現之言語資訊之能力增加,且因此記得寫下並完成家庭作業。類似地,認知訓練方案可針對自閉症個體中妨礙該個體實施指令來完成諸如做飯、清潔房間或在早上為上學作準備等活動之受損的執行功能。認知訓練允許個體集中其注意力及集中力,且因此完成該等活動所需之作業排序。
基於技能之訓練旨在改善具體活性或能力之效能。在此處,訓練之目標係獲得技能或能力之一般改善。例如,訓練方案可致力於學習新語言,演奏樂器,改善記憶或學習精細運動技能。該方案內之不同鍛煉將致力於構成技能基礎之核心組份。用於增加記憶之模組例如可包含針對識別及利用事實以及獲取並領會明確知識規則之作業。
一些復健程式可依賴靶向孤立的認知功能或同時多個功能之單一策略(例如電腦輔助之認知訓練)。例如,CogState測試方法包括可定製之多個電腦化認知作業,該等作業能夠量測注意力、記憶、執行功能以及語言及社交感情型認知之基礎認知結構域之基線及變化(例如,Yoshida等人,PloS ON,2011,6,e20469;Frederickson等人,Neuroepidemiology 2010,34,65-75)。其他復健程式可使用整合或跨學科方式。認知及運動訓練程式可涉及電腦遊戲、手持式遊戲器件、交互式鍛煉,且可採用反饋及適應模型。
在其他實施例中,本發明進一步係關於本發明化合物及組合物在為恢復神經系統之認知及運動損害之中心之內源性神經生物學過程之神經恢復及神經復健中之用途(例如,Harkema等人,Arch.Phys.Med.Rehabil.2012,93,1588-1597;Muresanu等人,J.Cell.Mol.Med.2012,16,2861-2871)。
神經復健或神經恢復通常係指致力於幫助個人自神經病症恢復或幫助個體過上更正常、積極且獨立之生活之收集過程。例如,個人之生活品質可極大地受腦或脊髓損傷或影響活動性、認知功能或已受神經系統變化影響之其他物理或心理過程之醫學病況的影響。神經復健之目標係藉由眾多種療法抵抗彼等變化並改善生活品質。
在本發明範疇內經神經復健及神經恢復治療之病況包含:中風;創傷性腦損傷(TB);癡呆;阿茲海默氏病;帕金森氏病;亨廷頓氏病;大腦性麻痺;小兒麻痺後症候群;格林-巴利症候群及多發性硬化症;及其他發展症候群、遺傳病及侵襲認知功能之進行性CNS疾病,例如自閉症譜系障礙、胎兒酒精譜系障礙(FASD)、魯塔二氏症候群、唐氏症候群及其他形式之心智遲滯。
藉由致力於個人康健之所有態樣,神經復健或神經恢復提供自心理至職業之一系列療法,教示或再訓練患者之活動性技能、溝通過程及此人之日常生活之其他態樣。神經復健或神經恢復亦提供對個人恢復之營養、心理及創造性部分之關注。
在一實施例中,本發明提供自認知損害加強神經復健或神經恢復之方法,其包括:(a)在足以使該動物之與認知缺陷相關之認知功能損害達成改善效能的條件下,向需要治療該認知缺陷之個體提供認知訓練;(b)在結合該認知訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由認知訓練所達成之改善該功能效能,可以達成長期改善該功能效能。
在另一實施例中,本發明提供自運動損害加強神經復健或神經恢復之方法,其包括:(a)在足以使該動物之與認知缺陷相關之運動功能損害達成改善效能的條件下,向需要治療該運動缺陷之個體提供運動訓練;(b)在結合該運動訓練下,向動物投與本發明化合物或組合物;(c)重複步驟(a)及(b)一或多次;及(d)相對於僅由運動訓練所達成之改善效能,可以減少足以達成相同改善效能時之訓練期數。
除應用於人類外,本發明化合物及組合物具有針對非人類動物之額外用途,即增強(加強)針對多種認知及運動功能之訓練方案之效率。
其中非人類動物將有益之條件包含出於特定目的增強(加強)的訓練程序(例如獵犬、導盲犬、警犬等或用於電影工業之動物)。
增強的訓練方案亦可有益於已暴露於緊張或創傷性條件下且需要訓練來治療所得認知損害之動物。該需要可在例如該動物已經捕獲或運輸、經歷新圈養條件後產生(此乃因住所或所有者改變),或在已罹患類似病症且沮喪或具有攻擊性或展示定型化行為、強迫性行為或焦慮後產生。經歷緊張之動物亦將包含用於比賽(例如犬、馬、駱駝)或其他運動之動物、表演動物(例如馬戲團動物及出現在舞臺、電視或電影中之彼等)及表演花式騎術及其他高度紀律性慣例之馬。
本發明化合物亦可增強非人類動物之物理損傷(例如截肢)後復健方案之效率。例如,結合訓練方案投與本發明加強劑可藉由減少達成運動功能改善所需之訓練期數來增加復健程式之效率。
在具體實施例中,本發明化合物及組合物係用於訓練服務型動物之方法中。藉由組合本發明加強劑與訓練方案,將增強訓練用於公共及私人部門二者之服務之非人類動物之效率。服務動物通常為犬。然而,亦可訓練其他非人類動物來實施服務,例如援助盲人或殘疾
人。例如,可訓練迷你馬來引導盲人、推輪椅或為帕金森氏症患者提供支持。作為另一實例,可訓練捲尾猴來援助殘疾人實施手的作業,例如抓握物品、操作旋鈕及開關、翻動書頁。
在特定實施例中,使用本發明化合物及組合物之加強訓練可用於減少教示可用於公共服務(例如執法)之動物技能所需之訓練期數。在犬中,例如,該等技能包含(但不限於)以下各項:(i)公共秩序維護,例如,追蹤、捕捉或扣押嫌疑犯;(ii)搜救,例如,定位嫌疑犯、丟失的人或物;及(iii)違禁品檢測,例如,檢測諸如藥物、麻醉劑、爆炸物、武器及甚至人體遺骸等非法物質。因此,該等方法可適用於警犬、炸彈嗅探犬、藥物嗅探犬、搜救犬等。
在其他實施例中,加強訓練(使用本發明化合物及組合物)可用於減少教示可用於私人部門(例如安全及醫療護理)之動物技能所需之訓練期數。在犬中,例如,該等技能可包含(但不限於)以下各項:(i)私人安全,例如保衛財產或保護個體;(ii)殘障援助,例如為視覺受損者提供眼睛,為聽力受損者提供耳朵,為身體殘疾者提供臂及腿;(iii)健康護理,例如檢測癌症或提醒護理者某個體之癲癇發作;(iv)精神病援助,例如使恐懼個人在緊張觸發之條件下鎮定,或提醒自閉症者以轉移在諸如拍手等重複運動方面之注意力;及(v)害蟲控制,例如鑒定臭蟲或白蟻之傳染源。
在一些實施例中,訓練方案可針對單一技能或作業,例如檢測單一藥物。在其他實施例中,訓練方案可針對一組複雜技能,例如搜救之基礎技能。因此,對於一組複雜技能,訓練將包括一種以上之作業。
在另一態樣中,當訓練係與足夠寬範疇之作業一起實施時,預期廣泛性「復健」效應,以使得廣泛性改善一或多個認知結構域之功能。此使得改善動物之不屬於訓練方案中特定部分之相關作業的效能
(涉及相同的認知結構域)。
因此,本發明提供減少教示動物一或多種技能所需之時間之方法,其中該減少包括:a)向動物投與本發明之加強劑;b)在改善一或多個作業效能之條件下向該犬提供訓練方案,其中該訓練方案包括多個訓練期;及c)相對於僅藉由訓練方案產生該效能改善所需之該等訓練期數,可以減少改善該一或多個作業效能所需之訓練期數。
可在改善以下各項之效能之條件下向動物提供該訓練方案:單一作業;一組複雜作業;或寬範疇之作業,以使得廣泛性改善一或多個認知結構域之功能。該等作業可與參與公共服務(例如公共秩序維護、搜救及違禁品檢測)之技能相關。該等作業亦可與參與私人服務(例如私人安全、殘障援助、健康護理、精神病援助及害蟲控制)之技能相關。
PDE4酶位於多種外周組織中。例如,一或若干種PDE4D亞型在大多數所測試組織(包含皮質、海馬、小腦、心臟、肝臟、腎臟、肺及睪丸)中表現(Richter等人,Biochem.J.,2005,388,803-811)。業內認為PDE4D亞型之定位及調控允許嚴格及局部調控cAMP含量,此可限制信號在特定亞細胞隔室中之傳播。
因此,在一實施例中,本發明提供治療與PDE4相關之外周病症之方法,其包括向有需要之動物投與治療有效量之本文所闡述之化合物或醫藥組合物。
外周病症可包含(但不限於)諸如以下等PDE4相關病症:發炎性腸病(Banner及Trevethick,2004,Trends Pharmacol.Sci.25,430-436);類風濕性關節炎(Kobayashi等人,2007,Mediators Inflamm.2007,58901);慢性阻塞性肺病(COPD)、氣喘、過敏性鼻炎、肺動脈高血壓(DeFranceschi等人,2008,FASEB J.,22,1849-1860);腎病
(Conti等人,2003,J.Biol.Chem.,278,5493);過敏性皮膚病及牛皮癬(Baumer等人,2007,Inflamm.Allergy Drug Targets,6,17-26)。
藉由以下非限制性實例將進一步闡釋本發明。該等實例應理解為僅具有實例性,且在本文中不應將其理解為限制本發明之範疇,且應理解為由隨附申請專利範圍來定義。
現將參考下文用於其一般製備及下文特定實例之闡釋性合成方案來闡述可用於本發明方法中之實例性化合物。
熟習此項技術者將意識到,為獲得本文之眾多種化合物,可適宜地選擇起始材料,以使最終期望取代基係經由在適宜時具或不具保護之反應方案攜載以產生期望產物。另一選擇為,可能需要或期望採用可經由反應方案攜載且在適宜時經期望取代基替代之適宜基團來替代最終期望取代基。除非另有說明,否則變量係如上文參考式(I)所定義。可在-78℃與溶劑之回流溫度之間實施反應。可採用習用加熱或微波加熱來加熱反應物。亦可在密封壓力容器中,在溶劑之正常回流溫度以上來實施反應。

藉助以下藥理學實例進一步闡釋本發明。該等實例應理解為僅具有實例性,且並不意欲限制本文所揭示之本發明範疇。
使用PDE4D3亞型研發基於IMAP TR-FRET之PDE分析。IMAP技術係基於藉由將金屬(MIII)配位複合物固定在奈米粒子上之磷酸根之高親和力結合。在PDE反應中,IMAP「結合試劑」識別自cAMP或cGMP產生之AMP或GMP上之磷酸根基團。該結合試劑並不識別攜載磷酸二酯鍵而非游離磷酸根之環狀核苷酸。藉由預結合至奈米粒子之鋱(Tb)供體來提供時間解析螢光共振能量轉移(TR-FRET)。FRET可在PDE反應結合物之螢光標記之AMP或GMP產物緊密靠近Tb供體複合物時進行。由於Tb螢光之壽命較長,故可以時間解析模式來運行檢測以消除來自自體螢光化合物之干擾。
在1536孔白色板上實施IMAP TR-FRET PDE4D3 FAM-cAMP分析。將15pg/孔GST標記之PDE4D3分散於2.5μL IMAP分析緩衝液
中,該緩衝液係由10mM Tris(pH 7.2)、10mM MgCl2、1mM DTT、0.1%脂肪酸游離BSA及0.01% Tween-20組成。然後使用Kalypsys 1536 10nL加樣頭自於DMSO中之1mM儲備溶液添加30nL化合物。在室溫下將板培育5min,然後分散1.5μL 533nM FAM-cAMP,使最終濃度為200nM。短暫離心後,在室溫下將板培育30min。藉由將根據製造商之建議製備之5μL IMAP結合試劑Tb複合物添加至每孔中來終止分析。在室溫下將板再培育90分鐘且在Viewlux板讀取器上讀取。在PDE4D3分析中,化合物係以10mM溶合於DMSO中且在11點劑量-反應中測試。
在PDE4酶促分析中評估本發明之代表性化合物。通常,本發明化合物在0.1μM至10μM之濃度下顯示通常為5%-100%之PDE4抑制性質。
如下表中所繪示,該等抑制性質係由介於小於5(10-5M或10μM)至大於7(10-7M或0.1μM)範圍內之pEC50值來反映。

多種行為分析可用於評估候選化合物增強記憶形成之能力,包含情境制約(例如,害怕制約)、時間制約(例如,痕跡性制約)及目標
識別。適於評估記憶之分析之其他非限制性實例包含納入或關於以下各項之彼等:多個訓練期、間隔訓練期、伴有單一或多個試驗之情境害怕訓練、伴有單一或多個試驗之痕跡性害怕制約、一般情境記憶、時間記憶、空間記憶、情景記憶、被動迴避記憶、主動迴避記憶、食物偏好記憶、條件性味覺迴避及社交識別記憶。
行為分析亦可如彼等熟習此項技術者將理解根據本發明來使用。該等分析可針對評估(但不限於)海馬、皮質及/或杏仁體依賴性記憶形成或認知效能。
情境害怕制約係一種聯想學習形式,其中動物學習識別先前已與諸如足部電擊等反向刺激((非條件刺激,US))配對之訓練環境(條件刺激,CS)。當在隨後時間暴露於相同背景下時,條件動物顯示眾多種條件性害怕反應,包含呆滯行為。在動物展現該呆滯之測試期間之時間%提供情境聯想記憶之量化量測(例如,Fanselow,Behav.Neurosci.1984,98,269-277;Fanselow,Behav.Neurosci.1984,98,79-95;以及Phillips及LeDoux,Behav.Neurosci.1992,106,274-285)。
情境制約已廣泛用於研究介導害怕主動學習之神經基質(例如,Phillips及LeDoux,Behav.Neurosci.1992,106,274-285;Kim等人,Behav.Neurosci.1993,107,1093-1098;及Bourtchouladze等人,Learn.Mem.1998,5,365-374)。小鼠及大鼠中之研究提供在情境制約訓練期間海馬與非海馬系統之間之功能性相互作用的證據(例如,Maren等人,Behav.Brain Res.1997,88,261-274;Maren等人,Neurobiol.Learn.Mem.1997,67,142-149;及Frankland等人,Behav.Neurosci.1998,112,863-874)。特定而言,海馬之訓練後病灶(而非訓
練前病灶)極大地減少情境害怕,此暗示:1)海馬為情境記憶而非情境學習本身所必需,及2)在訓練期間海馬不存在下,非海馬系統可支持情境制約。
情境制約已廣泛用於研究眾多種突變對海馬依賴性學習之影響以及小鼠中之菌株及遺傳背景差異(例如,Bourtchouladze等人,Cell 1994,79,59-68;Bourtchouladze等人,Learn Mem.1998,5,365-374;Kogan等人,Current Biology 1997,7,1-11;Silva等人,Current Biology 1996,6,1509-1518;Abel等人,Cell 1997,88,615-626;Giese等人,Science 1998,279,870-873;Logue等人,Neuroscience 1997,80,1075-1086;Chen等人,Behav.Neurosci.1996,110,1177-1180;及Nguyen等人,Learn Mem.2000,7,170-179)。
由於幾分鐘訓練期可觸發強健式學習,故情境制約尤其可用於研究短期及長期記憶之時間不同過程之生物學(例如,Kim等人,Behav.Neurosci.1993,107,1093-1098;Bourtchouladze等人,Cell 1994,79,59-68;Abel等人,Cell 1997,88,615-626;Logue等人,Behav.Neurosci.1997,111,104-113;Bourtchouladze等人,Learn.Mem.1998,5,365-374;及Nguyen等人,Learn.Mem.2000,7,170-179)。因此,情境制約提供評估新穎藥物化合物對海馬依賴性記憶形成之效應之極佳模型。
先前研究已確立,具有1×或2×CS-US配對之訓練在野生型小鼠中誘導次於最大(弱)之記憶(例如,U.S.2009/0053140;Tully等人,Nat.Rev.Drug Discov.2003,2,267-77;及Bourtchouladze等人Learn.Mem.1998,5,365-374)。因此,此研究中,依Bourtchouladze等人,Cell 1994,79,59-68中所述來進行情境制約。
使用年輕成年(10-12週齡)C57BL/6雄性小鼠及史泊格多利雄性
大鼠。將小鼠及大鼠分組圈養於標準實驗室中且維持在12:12光照-黑暗循環下。實驗始終在循環之光照期實施。除測試時間外,小鼠可以自由取得食物及水。為評估情境記憶,採用原始研發用於分析CREB基因敲除小鼠之記憶之經修改之情境害怕制約作業(Bourtchouladze等人,1994)。訓練期包括在制約室(Med Associates公司)中之基線時段,隨後以分隔60秒之間隔呈送非制約刺激(1-5次足部電擊,每次在0.2-1.0mA下持續2秒)。在最後一次電擊後30秒時,使動物返回圈養籠中。1至7天後,使動物返回試驗室中,且對呆滯行為進行評分。呆滯(除呼吸外之完全不動性)係藉由Video Freeze軟體(Med Associates公司)經8分鐘測試時段來評分。預期使用認知增強劑治療時,將會比對照組顯著增加呆滯。
所有實驗皆依相對平衡方式來設計及實施。在每一實驗中,實驗者不知道(盲目)在訓練及測試期間個體之治療。將訓練及測試期記錄為數位檔案。藉由單因子ANOVA與適當之事後試驗法,使用GraphPad Prism套裝軟體分析數據。
在害怕制約分析中發現,實例化合物可增強情境記憶。在包括0.01mg/kg、0.03mg/kg及1.0mg/kg之數種濃度下,可見到顯著增強效應。
新穎目標識別(NOR)係一種識別學習及記憶檢索之分析,且其利用齧齒類動物研究新穎目標與熟悉目標相比之自發偏好性。其係在行為學上相關之作業,與害怕制約相比,其並非源自負向強化(足部電擊)(例如,Ennaceur及Delacour,Behav.Brain Res.1988,31,47-59)。
NOR測試已廣泛用於評估源自高通量篩選之新穎化合物之潛在的認知增強性質。目標識別作業依賴於齧齒類動物探究其環境中之新穎目標強於熟悉目標之天然好奇心。顯而易見,對於「熟悉」之目標,動物必須在之前已注意到該目標且記住該經歷。因此,具有較佳記憶之動物將注意及探究新目標多於其所熟悉之目標。在測試期間,向動物呈送訓練目標及第二新穎目標。訓練目標之記憶使其為動物所熟悉,且然後該動物花費更多時間來探究新穎目標而非熟悉目標(Bourtchouladze等人,Proc.Natl.Acad.Sci.USA 2003,100,10518-10522)。
神經顯影、藥理學及病灶研究已展示,海馬及毗鄰鼻週皮質對於齧齒類動物、猴及人類之目標識別記憶至關重要(例如,Mitchell,Behav.Brain Res.1998,97,107-113;Teng等人,J.Neurosci.2000,20,3853-3863;Mumby,Brain Res.2001,127,159-181;Eichenbaum等人,Annu.Rev.Neurosci.2007,30,127-152;Squire等人,Nat.Rev.Neurosci.2007,8,872-883;以及Vann及Alabasser,Curr.Opin.Neurobiol.2011,21,440-445)。因此,目標識別提供評估藥物化合物對與海馬及皮質功能相關之認知作業之效應的極佳行為模型。
在年輕成年小鼠及大鼠中使用以下方案測試目標識別。在訓練前2-5天由實驗者對動物進行簡單處理。在訓練之前或之後15分鐘與24小時之間投與每一化合物。實施習慣期(持續1-20min,經1-3天)以使動物熟悉活動場所。在訓練試驗(持續1-20min)期間,允許動物探究兩個相同目標。然後在隨後1-96hr內實施測試試驗(持續1-20min)。
對於新穎目標識別,使用一個新穎目標替代一個目標。以平衡方式使用目標之所有組合及位置以減少因對具體位置或目標之偏好性
所致之潛在偏差。記錄訓練及測試試驗並藉由視頻追蹤軟體(例如Noldus Ethovision)來評分。當動物頭部定向朝向目標在1cm(大鼠)/2cm(小鼠)距離內時或當鼻碰觸目標時,將其評定為探究目標。圍繞目標轉動、攀爬目標或坐於目標上並不視為探究。若動物產生針對熟悉目標之長期記憶,則在保持測試期間與熟悉目標相比,其將顯著花費更多時間來探究新穎目標(因此預期認知增強劑促進熟悉與新穎目標之間之此差別)。
如先前所闡述(Bourtchouladze等人,Proc.Natl.Acad.Sci.USA 2003,100,10518-10522)來計算差別指數。在每一實驗中,實驗者不知道(盲目)在訓練及測試期間個體之治療。藉由單因子ANOVA與適宜事後測試使用GraphPad Prism軟體包來分析數據。
