Description
本發明係關於一種具有組蛋白去乙醯酶6 (HDAC6)抑制活性之新穎化合物、其立體異構體、其醫藥學上可接受之鹽;其用於製造預防性或治療性藥劑之用途;包含其之醫藥組合物;其預防或治療方法;及其製備方法。
在細胞中,諸如乙醯化之轉譯後修飾在生物過程之中心充當極其重要的調節模組,且亦受到多種酶的嚴格控制。作為構成染色質之核心蛋白,組蛋白充當被DNA捲繞的軸,且因此有助於DNA縮合。另外,組蛋白之乙醯化與去乙醯化之間的平衡在基因表現中發揮著極其重要的作用。
作為用於自構成染色質之組蛋白蛋白質之離胺酸殘基移除乙醯基的酶,組蛋白去乙醯酶(HDAC)已知與基因靜默相關且誘導細胞週期停滯、血管生成抑制、免疫調節、細胞凋亡等(Hassig等人, Curr. Opin. Chem. Biol. 1997, 1, 300-308)。另外,據報導,抑制HDAC酶功能係藉由降低癌細胞存活相關因子之活性及活化體內癌細胞死亡相關因子來誘導癌細胞自行凋亡(Warrell等人, J. Natl. Cancer Inst. 1998, 90, 1621-1625)。
就人類而言,已知18種HDAC且根據與酵母HDAC之同源性分為四類。在此情況下,使用鋅作為輔因子之十一種HDAC可分成三類:I類(HDAC1、2、3、8)、II類(IIa:HDAC4、5、7、9;IIb:HDAC6、10)及IV類(HDAC11)。另外,III類的七種HDAC (SIRT 1至7)使用NAD+代替鋅作為輔因子(Bolden等人, Nat. Rev. Drug Discov. 2006, 5(9), 769-784)。
各種HDAC抑制劑現處於臨床前或臨床開發階段,但迄今為止僅已知非選擇性HDAC抑制劑為抗癌劑。伏瑞斯特(vorinostat)(SAHA)及羅米地辛(romidepsin)(FK228)已獲批作為皮膚T細胞淋巴瘤之治療劑,而帕比司他(panobinostat)(LBH-589)已獲批作為多發性骨髓瘤之治療劑。然而,已知非選擇性HDAC抑制劑一般在高劑量下會產生副作用,諸如疲勞、噁心及其類似作用(Piekarz等人, Pharmaceuticals 2010, 3, 2751-2767)。據報導,該等副作用係由對I類HDAC之抑制引起。歸因於該等副作用等,非選擇性HDAC抑制劑在除抗癌劑以外的其他領域中受到藥物開發之限制(Witt等人, Cancer Letters 277 (2009) 8-21)。
同時,據報導,選擇性抑制II類HDAC不顯示毒性,而在抑制I類HDAC時已出現毒性。在開發選擇性HDAC抑制劑之情況下,有可能解決非選擇性抑制HDAC所引起的副作用,諸如毒性等。因此,可有機會開發選擇性HDAC抑制劑作為各種疾病之有效治療劑(Matthias等人, Mol. Cell. Biol. 2008, 28, 1688-1701)。
已知HDAC6 (IIb類HDAC之一)主要存在於細胞質中且涉及包括微管蛋白蛋白質在內之多種非組蛋白基質(HSP90、皮層肌動蛋白(cortactin)等)的去乙醯化(Yao等人, Mol. Cell 2005, 18, 601-607)。HDAC6具有兩個催化域,其中C端鋅指域可結合至泛素化蛋白質。已知HDAC6具有多種非組蛋白蛋白質作為基質,且因此在各種疾病中起重要作用,該等疾病諸如癌症、發炎疾病、自體免疫疾病、神經疾病、神經退化病症及其類似疾病(Santo等人, Blood 2012 119, 2579-2589;Vishwakarma等人, International Immunopharmacology 2013, 16, 72-78;Hu等人, J. Neurol. Sci. 2011, 304, 1-8)。
各種HDAC抑制劑共同具有之結構特徵包含封端基團、連接子及鋅結合基團(ZBG),如以下伏立諾他(vorinostat)結構中所示。許多研究人員已藉由封端基團及連接子之結構修飾對關於酶之抑制活性及選擇性進行研究。除該等基團以外,已知鋅結合基團在酶抑制活性及選擇性方面起更重要的作用(Wiest等人, J. Org. Chem. 2013 78: 5051-5055;Methot等人, Bioorg. Med. Chem. Lett. 2008, 18, 973-978)。
大部分該鋅結合基團包含異羥肟酸或苯甲醯胺,除此之外,異羥肟酸衍生物顯示強HDAC抑制作用,但具有生物可用性低及脫靶活性嚴重的問題。苯甲醯胺含有苯胺,且因此具有可能在活體內產生有毒代謝物之問題(Woster等人, Med. Chem. Commun. 2015, online publication)。
因此,與具有副作用之非選擇性抑制劑不同,需要開發選擇性HDAC6抑制劑,該抑制劑具有生物可用性改善之鋅結合基團,同時不引起副作用,以便治療癌症、發炎疾病、自體免疫疾病、神經疾病、神經退化病症及其類似疾病。

將受孕第17天至第18天(E17-18)的史泊格-多利(Sprague-Dawley,SD)大鼠胎兒之海馬體神經元在培養容器中培養七天以用於成像,該培養容器經細胞外基質塗覆,且用濃度為1 M澱粉狀蛋白-β蛋白質片段處理。24小時後,在活體外培養第8天用化合物處理神經元。三小時後,用MitoTracker Red CMXRos (Life Technologies,NY, USA)處理所得神經元持續五分鐘以將粒線體染色。使用共焦顯微鏡(Leica SP8;Leica微系統,UK),歷時一分鐘、以一秒間隔來拍攝染色神經元粒線體之軸突轉運影像,以便用IMARIS分析程式(BITPLANE,Zurich,Switzerland)量測各粒線體之每秒轉運速度。
因此,在固定切片(其中澱粉狀蛋白-β處理組顯示的粒線體轉運速度相較於媒劑顯著降低)之後,對於本發明之1,3,4-㗁二唑三唑化合物、其立體異構體或其醫藥學上可接受之鹽而言,已證實該化合物在相對於媒劑100%及澱粉狀蛋白β處理組0%標準化之後顯示如下所示的速度分佈:*:0%至50%;**:50%至100%;***:>100%。
