在已驚人地發現,通式I之化合物係代謝型麩胺酸受體4(mGluR4)之正向別位調節劑(PAM)。
代謝型麩胺酸受體4係人類中由GRM4基因編碼之蛋白質。
其與GRM6、GRM7及GRM8一起屬代謝型麩胺酸受體家族之III組,且經由Gαi/o蛋白質之活化與腺苷酸環化酶負向偶合。其主要在突觸前末梢表現,用作自體受體或異源受體且其活化導致自突觸前末梢之遞質釋放減少。mGluR4主要基於其獨特分佈及此受體之活化在許多CNS及非CNS路徑中起關鍵調節作用的最近證據目前正受到許多關注(Celanire S,Campo B,Expert Opinion in Drug Discovery,2012)。
III組mGluR之配體結合結構域中之類似性對鑑別此受體之選擇性正位激動劑產生挑戰,但此領域中已取得一些進步。然而,靶向正向別位調節劑(PAM)而非正位激動劑為鑑別在mGluR之間具有排他選擇性之分子提供更寬機會。
mGluR4 PAM出現作為用於治療運動(及非運動)症狀之有前景之治療劑以及經由非多巴胺能方法在帕金森氏病(Parkinson’s disease)中之疾病改良劑。
帕金森氏病係導致黑質(SN)中之多巴胺能神經元損失之進行性神經退化疾病。此疾病中多巴胺之耗盡之一個後果係一系列運動障礙,包括運動遲緩、運動不能、顫抖、步態障礙及平衡問題。該等運動紊亂形成PD之標誌,但存在許多與疾病相關之其他非運動症狀。在疾病過程早期,PD症狀藉由多巴胺替代或增強使用多巴胺D2受體激動
劑、左旋多巴(levodopa)或單胺氧化酶B抑制劑可有效治療。然而,隨著疾病進展,該等藥劑在控制運動症狀中較不有效。另外,其使用受副作用(包括多巴胺激動劑誘導之運動困難)之出現限制。因此,仍需要改良運動症狀之控制之有效性的治療PD之新方法。
已提出代謝型麩胺酸受體4(mGluR4)之活化作為帕金森氏病之潛在治療方法。III組mGluR之成員mGluR4主要係在控制運動之基底神經節迴路中之若干關鍵位置中表現的突觸前麩胺酸受體。用III組偏好激動劑活化mGluR4大概藉由分別減少GABA及麩胺酸鹽之釋放減少抑制及興奮性突出後電位。
減輕帕金森氏症之運動症狀、同時減弱黑質紋狀體神經元之進行中變性之新穎藥物的搜尋尤其令人感興趣。已證實正位mGluR4激動劑L-AP4在PD之6-OHDA齧齒類動物模型中具有神經保護性效應且第一正向別位調節劑(-)-PHCCC在經1-甲基-4-苯基-1,2,3,6-四氫吡啶(MPTP)處理之小鼠中減輕黑質紋狀體變性。該等研究提供令人信服之臨床前證據表明,mGluR4活化劑構成不僅對PD之對症治療而且潛在作為用於此適應症之疾病改良劑的有效方法。
選擇性mGluR4調節劑之神經保護性效應亦闡述於Neuroreport,19(4),475-8,2008,Proc.Natl.Acad.Sci,USA,100(23),13668-73,2003及J.Neurosci.26(27),7222-9,2006及Mol.Pharmacol.74(5),1345-58,2008中。
在世界上,焦慮症係最流行之精神病,且與帕金森氏病共病(Prediger R,等人Neuropharmacology 2012;62:115-24)。過度麩胺酸能神經傳遞在病理生理學上係焦慮症之一個重要特徵。基於腦區域中參與焦慮症及情緒障礙及降低過度腦興奮性之mGluR4之突觸前位置,mGluR4活化劑可代表新一代抗焦慮治療劑(Eur.J.Pharmacol.,498(1-3),153-6,2004)。
Addex於2010年報導,ADX88178在焦慮症之兩個臨床前齧齒類動物模型中有活性:小鼠中之大理石埋葬測試及小鼠及大鼠中之EPM。ADX88178亦在經口投藥後在大鼠EPM測試中展示抗焦慮樣特性。
亦顯示mGluR4調節劑發揮抗抑鬱作用(Neuropharmacology,46(2),151-9,2004)。
另外,亦顯示mGluR4調節劑參與升糖素分泌抑制(Diabetes,53(4),998-1006,2004)。因此,mGluR4之正位或正向別位調節劑儘管其低血糖效應仍具有治療2型糖尿病之潛能。
此外,顯示mGluR4在前列腺癌細胞系(Anticancer Res.29(1),371-7,2009)或結腸直腸癌(Cli.Cancer Research,11(9)3288-95,2005)中表現。因此,mGluR4調節劑可亦具有治療癌症之潛在作用。
可預計mGluR4 PAM之其他提出效應用於治療嘔吐、強迫症、厭食症及自閉症。
式I化合物因具有有價值之治療性質而著名。其可用於治療或預防與mGluR4受體之別位調節劑有關之病症。
作為mGluR4受體之別位調節劑之化合物的最佳適應症係帕金森氏病、焦慮症、嘔吐、強迫症、厭食症、自閉症、神經保護、癌症、抑鬱症及2型糖尿病。
本發明係關於式I化合物及其醫藥上可接受之鹽、作為醫藥活性物質之該等化合物、其產生方法以及其用於治療或預防與mGluR4受體之別位調節劑有關之病症(例如帕金森氏病、焦慮症、嘔吐、強迫症、自閉症、神經保護、癌症、抑鬱症及2型糖尿病)的用途及含有式I化合物之醫藥組合物。
本發明之又一目的係治療或預防帕金森氏病、焦慮症、嘔吐、強迫症、厭食症、自閉症、神經保護、癌症、抑鬱症及2型糖尿病之

產生經編碼人類mGlu4受體之cDNA穩定轉染之單株HEK-293細胞系;對於利用mGlu4正向別位調節劑(PAMs)之研究,選擇具有低受體表現程度及低組成型受體活性之細胞系以允許區別激動劑活性與PAM活性。根據標準方案(Freshney,2000)在具有高葡萄糖補充1mM麩醯胺酸、10%(vol/vol)熱不活化之小牛血清(bovine calf serum)、青黴素(Penicillin)/鏈黴素、50μg/ml潮黴素及15μg/ml殺稻瘟菌素(blasticidin)(所有細胞培養試劑及抗生素均來自Invitrogen,Basel,Switzerland)之杜貝克氏改良鷹氏培養基(Dulbecco's Modified Eagle Medium)中培養細胞。
在試驗前大約24hr,將5×104個細胞/孔接種於聚-D-離胺酸塗佈之黑色/透明底的96孔板中。細胞經裝載於裝載緩衝液(loading buffer)(1×HBSS,20mM HEPES)中之2.5μM Fluo-4AM於37℃持續1hr,並用裝載緩衝液洗五次。將細胞轉移至功能藥物篩選系統(Functional Drug Screening System)7000(Hamamatsu,Paris,France)中,並於37℃添加測試化合物之11個半對數連續稀釋液,並將細胞培育10-30min,同時線上記錄螢光。在此預培育步驟之後,將激動劑(2S)-2-胺基-4-膦醯丁酸(L-AP4)以對應於EC20之濃度添加於細胞中,同時線上記錄螢光;為說明細胞反應性之每日變化,在各試驗之前即藉由L-AP4之全劑量-反應曲線之記錄決定L-AP4之EC20。
以螢光減去基線(即不添加L-AP4下之螢光)之峰值增加測量反應,將其正規化於利用L-AP4之飽和濃度獲得之最大刺激效應。利用XLfit繪製最大刺激%之曲線圖,XLfit係利用Levenburg Marquardt算
法以迭代方式對數據繪製曲線之曲線擬合程式。所用之單一位點競爭分析方程式係y=A+((B-A)/(1+((x/C)D))),其中y係最大刺激效應%,A係y最小值,B係y最大值,C係EC50,x係競爭化合物濃度之log10且D係曲線斜率(希爾係數(Hill Coefficient))。根據該等曲線,計算EC50(達成最大受體活化之50%之藥物濃度)、希爾係數,以及最大反應,其係以利用L-AP4之飽和濃度獲得之最大刺激效應%表示(參見圖1)。
在與PAM測試化合物一起預培育期間(即,在施加EC20濃度之L-AP4之前)所獲得之正信號指示激動活性,缺少該等信號表明缺乏激動活性。添加EC20濃度之L-AP4之後所觀察到的信號衰減指示測試化合物之抑制活性。
