Description
本申請涉及新穎的取代的6,7-二氫-5H-苯并[7]輪烯化合物、其製備方法及其治療用途特別是通過對雌激素受體的選擇性拮抗和降解作為抗癌劑的用途。
雌激素受體(ER)屬類固醇/核受體超家族,其在靶組織中參與對真核基因表達、細胞增殖和分化的調節。ER具有兩種形式:雌激素受體α(ERα)和雌激素受體β(ERβ),其分別由ESR1和ESR2基因編碼。ERα和ERβ為由配體激活的轉錄因子,其由雌激素(身體產生的最強效的雌激素為17β-雌二醇)激活。在沒有激素的情況下,ER大部分位於細胞的胞質溶膠中。當雌激素結合至ER時,ER由胞質溶膠遷移至細胞核,形成二聚體,然後結合至稱為雌激素反應單元(ERE)的特異性基因組序列。DNA/ER複合物與共調節子相互作用以調節靶基因的轉錄。
ERα主要表達在生殖組織例如子宮、卵巢、乳腺、骨和白色脂肪組織中。異常的ERα信號傳導導致多種疾病例如癌症、代謝疾病、心血管疾病、神經變性疾病、炎性疾病和骨質疏鬆的發展。
ERα表達在不多於10%的正常乳腺上皮中,但是表達在約50-80%的乳腺腫瘤中。將具有高水平的ERα的此類乳腺腫瘤歸類為ERα陽性乳腺腫瘤。雌激素在乳腺癌中的病因學作用已被充分確認且對ERα信號傳導的調節仍然是針對大部分ERα陽性乳腺腫瘤的乳腺癌治療的主要方式。目前存在幾種用於在乳腺癌中抑制雌激素軸的策略,包括:1-通過芳香酶抑制劑阻斷雌激素合成(其用於治療早期和晚期ERα陽性乳腺癌患者);2-通過他莫昔芬拮抗雌激素配體與ERα的結合(其用於治療絕經前和絕經後的ERα陽性乳腺癌患者);3-通過氟維司群拮抗和下調ERα水平(其用於治療儘管接受了內分泌療法例如他莫昔芬或芳香酶抑制劑但是已經進展的乳腺癌患者)。
儘管這些內分泌療法已經極大地有助於減少乳腺癌的發展,但是多於約三分之一的ERα陽性患者隨著時間推移對此類現有療法顯示出新生抵抗或發展出抵抗。已經描述了幾種機制以解釋對此類激素療法的抵抗。例如,在用芳香酶抑制劑進行的治療中ERα對低雌激素水平的超敏感性,在他莫昔芬治療或多種生長因子受體信號傳導途徑中他莫昔芬的作用由拮抗劑作用向激動劑作用的轉變。最近在啟動激素療法後出現的ERα獲得性突變可在治療失敗和癌症進展中發揮作用。ERα中的某些突變特別是在配體結合域(LBD)中鑒定出的那些突變導致在沒有配體的情況下與DNA結合的能力且向激素賦予在具有此類突變受體的細胞中的獨立性。
大部分所鑒定的內分泌療法抵抗機制取決於ERα依賴性活性。對抗此類抵抗的一種新策略為如下停止ERα信號傳導:使用選擇性雌激素受體降解劑(SERD)將ERα由腫瘤細胞除去。臨床和臨床前數據顯示大多數抵抗途徑可通過使用SERD來阻止。
仍然需要提供具有良好降解功效的SERD。
G.M.Anstead等人已經描述了2,3-二芳基茚和2,3-二芳基茚酮作為雌激素受體結合劑(Journal of Medicinal Chemistry,1988,Vol.31,No.7,p.
1316-1326)。
R.McCague等人已經描述了(Z)-和(E)-4-羥基他莫昔芬的類似物且已經測試了其與雌激素受體的結合親和性(Journal of Medicinal Chemistry,1998,Vol.31,No.7,p.1285-1290)。
本申請目的是提供新穎的能夠選擇性拮抗和降解雌激素受體的用於治療癌症的化合物(SERD化合物)。
