Description

醯胺化合物及其應用
本發明係關於一種作為升糖素受體之拮抗劑或反激動劑之化合物、包含其之醫藥組合物、及該化合物或該組合物之用途。
糖尿病為公共衛生的重要議題，並且影響世界上數百萬人。二種可調節血糖恆定之重要賀爾蒙：胰島素和升糖素，於糖尿病中具有重要角色。升糖素由胰島細胞α所分泌，並且可促進肝醣分解以及糖質新生。此外，升糖素訊息亦可影響脂質代謝、食物攝取、心血管系統、以及脂肪組織重量。升糖素訊息傳導之拮抗作用長久以來被用於糖尿病的潛在治療方法，許多治療係利用干擾受體-配體之結合而完成。升糖素受體為B類G蛋白偶聯受體，並且主要於肝臟表現，其他組織則較少。小分子對於升糖素受體之拮抗作用可降低下游第二傳訊者(secondary messenger)，包括cAMP和鈣離子，致使糖質新生基因表現以及後續血糖提升。升糖素受體-/-之小鼠對於飲食引發之肥胖以及鏈佐黴素引發之糖尿病具有抗性。多種小分子升糖素受體拮抗劑近期已開始進行臨床試驗，並且，相對於安慰劑而言，對於降低血糖具有顯著功效。升糖素受體拮抗作用可藉由保護心肌細胞，對於心血管疾病亦有所助益。在升糖素受體不活化之模式小鼠中可具有較高存活率以及較低心肌梗塞後的衰竭。
因此，有必要研發新穎升糖素受體調節劑，並且具有較少、較低之不良副作用，以用於治療。
本發明係關於一種醯胺化合物，可作為治療升糖素相關疾病之升糖素受體調節劑。該些化合物可作為升糖素受體之拮抗劑或反激動劑，相較於已知的治療藥劑，更可提高調節升糖素受體之效率以降低血糖濃度，具有無法預期之功效。

實施例6：式(I)化合物之體外(in vitro)試驗
下文說明以2種體外試驗測試實施例1-5所製備之化合物之結果，並將結果揭示於表1-7。
升糖素cAMP抑制試驗
使用試驗套組：Cisbio cAMP Dynamic 2 kit偵測升糖素誘發之下游第二傳訊者cAMP。待測之化合物分別溶於DMSO(10mM)。為評估化合物抑制cAMP產生之能力，將待測化合物以序列稀釋之濃度給予具有升糖素受體(GCGR)過度表現之CHO-K1細胞或人類初代肝細胞(human primary hepatocyte)。 將細胞懸浮於含有0.1%(w/v)小牛血清白蛋白和800nM 3-異丁基-1-甲基黃嘌呤(IBMX)之漢克平衡鹽緩沖液(Hank's Balanced Salt solution(HBSS))，並且分置於384白色孔盤。將稀釋之化合物加入孔盤中培養30分鐘，其中DMSO最終濃度為1%。再於室溫以濃度相當於EC50(可刺激半數最大反應之藥物濃度的標記)之升糖素刺激細胞30分鐘。而後於各孔洞加入包含cAMP抗體和螢光受器之裂解緩衝液(lysis buffer)，再培養60分鐘。使用儀器：Molecular Devices SpectraMax Paradigm以及HTRF偵測匣紀錄結果，依據cAMP產生量，以非線性回歸計算化合物各自抑制cAMP產生之IC50值。
I125-升糖素結合試驗
以I125-升糖素競爭試驗(competition assay)測試各化合物之結合能力。自GCGR過度表現之CHO-K1細胞取得GCGR膜部分(membrane fraction)，並以1mg/ml之濃度保存。為評估化合物結合至GCGR之IC50，GCGR膜部分給予序列稀釋之化合物。膜部分稀釋調整為每孔7.5μg，溶於含有50Mm Tris緩衝液(pH 7.4)和0.5%(w/v)小牛血清白蛋白之70μL試驗緩衝液，並加入96孔盤中。膜部分與10μL稀釋化合物混合培養5分鐘，再於各孔洞加入20μL具有I125標記之升糖素(Perkin Elmer)，升糖素最終濃度為0.0625nM。將反應物置於25℃培養30分鐘，再移至塗佈0.5%(w/v)聚乙亞胺之過濾盤：Millipore MultiScreen GF/B Plate。過濾盤以包含50mM Tris之清洗緩衝液(pH 7.4)清洗2次，每次300μL。殘留之同位素以儀器：Hidex CHAMELEON V micro-beta counter偵測，各化合物結合至GCGR之IC50由非線性回歸計算。
表1-7揭示式(I)之172個例示化合物之結構和體外試驗活性。172個化合物均可結合至升糖素受體，並可抑制升糖素下游之cAMP之濃度，各化合物活性之差異以表中IC50表示(降低半數反應或結合之抑制劑之濃度)。
a 括號中的數字表示化合物以濃度30μM給予時之抑制率。
實施例7：比較式(I)化合物與結構近似之已知化合物之活性
挑選4種化合物用於比較結構近似之已知化合物之體外活性，與前述結構近似之已知化合物揭示於表8。
以HTRF方法偵測第二傳訊者cAMP之功能性試驗揭示給予化合物後GCGR下游訊息。HTRF cAMP試驗依以下步驟進行。預先將初代人類肝細胞和不同濃度之待測化合物共同培養，再以重組升糖素刺激，並依據cAMP產生量以非線性回歸計算IC50。
前述試驗結果揭示於表8。
結果顯示，四種式化合物式(I)相較於結構相似之已知化合物，更能抑制人類肝細胞產生cAMP。
其他實施例
本說明書所揭示之技術特徵可任意組合，個別特徵可由被用於相同、相等、或相似目的之另一特徵取代。故，若無特別說明，各特徵僅為相同或相似上位特徵之例示。
另，習知技術者可依據說明書而輕易確認本發明之重要特徵，且在不背離發明精神和範圍之前提下，變換或更動本發明，已用於不同用途或狀況。故，其他實施例亦揭露於請求項。
