200524864 九、發明說明: 【發明所屬之技術領域】 本發明提供一種式I化合物以及其用於治療和5-HT6 受體相關或受影響之中樞神經系統障礙。 【先前技術】 血清素(5-羥色胺)(5-HT)受體在人類和動物生理和行爲 功能上扮演重要角色。這些功能分佈於全身,受各種5-HT 受體所調節。目前已鑑定出約15種不同的人類5-HT受體亞 型,其中許多已清楚瞭解對人類的角色。最近被確認的5-HT 受體亞型爲5-HT6受體,其爲1 993年選殖自大鼠組織 (Monsma?F.J. ; Shen5Y. ; Ward?R.P. ; H amb 1 in ? Μ . W. Mo/e c wr 1 993,43,320〜327)以及隨後得自人類的組織 (Kohen,R. ; Metcalf,Μ·Α. ; Khan,Ν· ; Druck,T· ; Huebner,K·; Sibley,D.R. Journal of Neurochemistry 1996,66,47〜56) o jfc 匕 受體爲連接至腺苷酸環化酶(Ruat,M. ; Traiffort,E.; Arrang,J-M·; 丁ardivel-Lacombe,L· ; Diaz,L·: Leurs.R·: Schwartz. J -C. Biochemical Biophyscial Research Communications Λ 993,1 93, 268〜276)的G-蛋白質受體(GPCR)。此受體幾乎僅出現在大鼠 和人類的中樞神經系統(CNS)。大鼠腦內利用mRNA之5-HT6 受體的原位雜交試驗顯示5-HT主要出現區域包括紋狀體、 伏隔核(nucleus accumbens)、嗅覺球、海馬體(Ward,R.P.; Hamblin,M.W.; Lachowicz,J.E.; Hoffman,B.J·; Sibley,D.R.; Dorsa,D.M. Neuroscience 1 995,64,1105〜1111)。 根據5 -Η T 6配位體對人類的直接藥效以及根據科學報 200524864 告顯示其具有治療效果。這些試驗包括受體的定位、配位體 活體內已知活性的親和力以及迄今所進行的各種動物試驗。 5 -HT6受體功能之調節劑的治療用途爲加強如阿茲罕莫 症(A1 z h e i m e r ’ s )之人類患者的認知和記憶力。前腦的主要構 造中發現具有高密度的受體,其包括尾狀核/殻核、海馬體、 伏隔核和皮質,而且由於其爲已知的記憶關鍵區域,故認爲 其受體在記憶和認知上扮演某種角色(Gerard5C·; Martres,M· - Ρ· ; Lefevre,K. ; Miquel,M.C. ; Verge,D.; Lanfumey,R. ; Doucet,E. ; Hamon?M. ; El Mestikawy,S. Brain 心^^(:/2 1997,746,207〜219)。5-1^6受體配位體之已知加強 膽鹼激性傳導的效果亦可支持其在改善認知上的用途 (Bentley,J.C. ; Boursson,A. ; Boess,F.G. Kone,F.C.; Marsden,C.A. ; Petit?N. ; Sleight,A.J. British Journal of 1999,126(7),1537〜1542)。試驗發現一種已知 5-HT6的選擇性掊抗劑在正腎上腺素、度巴胺(dopamine)或 5-HT的濃度不上升之下仍可明顯增加前腦內的麩胺酸和天 門冬胺酸濃度。此已知和記憶及認知有關之神經化學物質的 選擇性上升爲5-HT6配位體在認知上扮演重要角色的強烈 證據(Dawson,L.A. ; Nguyen,H.Q. ; Li,P. 〇/ P/zarmflcdog;; 2000,130(1),23 〜26)。以已知選擇性 5-HT6 掊 抗劑進行記憶和學習的動物試驗發現具有某些正面的效果 (Rogers,D.C. ; Hatcher,P.D. ; Hagan,J.J. Society of 摘要 2000,26,680)。 5-HT6配位體可有效用於兒童和成人之注意力缺乏障礙 200524864 (ADD,注意力缺乏過動症或ADHD)的治療。由於5-ΗΤ 6拮 抗劑可加強紋狀體黑質徑路的活性並且已知ADHD和尾狀 核異常有關(Ernst,M. ; Zametkin,A.J. ; Matochik,J.H.; J ο n s ? P. A . ; C o h e n , R . M . Jour an l of Neuroscience 1 9 9 8,1 8 (15),5901〜5907),因此5-HT6可減緩注意力缺乏障礙。 早期利用習知的治療設備或極類似已知藥物之構造的 測定試驗證明5 -HT6配位體在治療精神分裂症和憂鬱症上 扮演某種角色。例如,可治律(clozapine)(—種有效的臨床抗 精神病藥)和5-HT6受體亞型具有高親和力。同時,許多臨 床抗憂鬱藥和該受體亦具有高親和力並且做爲該部位的拮 抗齊!J (Branchek,T. A. ; Blackburn,Τ·Ρ. Annual Reviews in 此外,最近大鼠活體內試驗顯示5-HT6調節劑可有效用 於治療包括癲癇之運動障礙(Stean,T. ; Routledge,C·; Upton,Ν· British Journal of Pharmacology 1999,127 補充 13 1 頁以及 Routledge,C. ; Bromidge,S.M. ·,Moss,S.F.; Price,G.W. ; Hirst5W. i Newman,H. ; Riley?G. ; Gager,T.; Stean,T.; Upton5N.; Clarke,S.E.; Brown?A.M. British Journal 〇/尸厶<3厂7?|(3<:〇/(9呈少 2000,130(7),1606〜1612)。 綜合上述的試驗可證明5-HT6受體調節劑,即配位體, 之化合物可有效治療的適應症包括:和記憶力、認知及學習 缺陷相關的疾病,例如阿茲罕莫症和注意力缺乏障礙;人格 異常障礙,例如精神分裂症;行爲異常,例如焦慮症、憂鬱 症和強迫症(obsessive compulsive disorder);移動或運動障 200524864 礙,例如帕金森氏症和癲癇;和神經變性病相關的疾病,例 如中風或腦創傷;或戒除毒癮,包括尼古丁、酒精和其他濫 用藥物。 因此,本發明提供一種化合物,可用於作爲有效治療和 5-HT6受體相關或導致之各種中樞神經系統障礙之治療劑。 本發明另一態樣爲提供一種用於有效治療和5 - Η T 6受 體相關或導致之中樞神經系統障礙之方法。 本發明所提供之化合物亦可用於5-ΗΤ6受體的進一步 硏究及說明。 【發明内容】 本發明提供式(I)之化合物: R4、|sTR5
