Description
本發明涉及醫藥領域,特別涉及4-苯胺-6-丁烯醯胺-7-烷醚喹唑啉類衍生物及其製備方法及含有該衍生物的藥物組合物以及其作為治療劑特別是作為erbB家族蛋白酪氨酸激酶(PTK)抑制劑的用途。
細胞信號傳導是一種基礎的作用機制。在信號傳導過程中,來自細胞外的刺激被傳遞到細胞內部,進而調節細胞的不同過程。這些受信號調節的過程包括細胞增殖、分化、凋亡和運動等。很多信號傳遞是通過生長因數與PTK跨膜受體酪氨酸蛋白激酶(RTK)結合來調節細胞內的過程。
許多RTK的不適當的或不受控制的啟動,即異常的RTK活性,例如過高的表達或突變將導致細胞生長或分化等不受正常的控制,從而導致疾病。已知因RTK異常活性所導致的疾病有牛皮癬,類風濕關節炎,多種癌症,以及血管生成、粥狀動脈硬化等疾病。RTK有多個亞族,其中一個亞族是erbB激酶家族,成員包括EGFr(又名ErbB1)、HER2(又名ErbB2)、HER3(又名ErbB3)和HER4(又名ErbB4)。這些RTK由細胞外糖基化配體結合域、跨膜域和可將蛋白質上酪氨酸序列進行磷醯化的細胞內細胞質催化域組成。其中HER3不含有能將蛋白質上酪氨酸序列進行磷醯化的細胞內細胞質催化域。RTK的催化活性可通過受體過度表達或配體介導二聚合而啟動。ErbB家族RTKs聚合體有同型二聚體和異型二聚體兩種形式。同型二聚體
一個例子為EGFr和EGF家族配體(包括EGF、轉化生長因數、betacellulin、epiregulin等)的聚合。ErbB家族RTKs之間的異體二聚合可通過heregulin(又名neuregulin)家族配體結合而加速。HER3雖然沒有受體激酶活性,但其與HER2或HER4的異型二聚可顯著刺激受體激酶的聚合及酪氨酸磷醯化催化活性。研究發現EGFr的過度啟動與一些過度增生的疾病如非小細胞肺癌、膀胱癌、頭頸部癌,腦癌等有潛在的關係,而增強的HER2活性已經涉及到乳房癌、子宮癌、卵巢癌、胃癌及胰腺癌等癌症。因此抑制erbB家族RTKs可以提供以異常erbB家族RTK活性為特徵的疾病的治療。已有多篇文獻討論erbB家族RTK的生物學作用,及其與各種疾病的關係,如以下文獻和專利:Reid,A.,et al.Eur.J.Cancer,2007,43,481;Doebele,R.C.,et al.Lung Cancer.2010,69,1-12;Ocana,A.;Amir,E.Cancer Treat Rev.2009,35,685-91;Minkovsky,N.et al.Current Opinion in Investigational Drugs 2008,9,1336-1346;WO2002/66445,WO1999/09016,US06627634等。
許多專利文獻中討論了RTK抑制劑或喹唑啉衍生物的相關技術,如WO9630347(中國專利申請CN96102992.7)涉及一些4-苯基胺喹唑啉類化合物用於治療過度增生疾病。WO9738973(中國專利申請CN97194458)和WO2009/140863(中國專利申請CN2009000557)公開了作為酪氨酸激酶不可逆抑制劑的製備和藥物用途。WO0006555(中國專利申請CN99808949)公佈了有關取代的喹唑啉衍生物具有抑制RTK活性的功能。WO9935146(中國專利申請CN99803887)披露了一系列的二環芳香雜環包
括喹唑啉化合物為RTK激酶抑制劑。另外,中國專利申請如CN01817895,CN93103556,CN98807303,CN96193526,CN01812051,CN99803887,CN0410089867,CN03811739;美國專利如US5521884,US6894051,US6958335,US5457105,US5616582,US5770599,US5747498,US6900221,US6391874,US6713485,US6727256,US6828320,US7157466中均提及多種喹唑啉類化合物具有抑制多種RTK活性的功能。已經有數個喹唑啉類激酶抑制劑藥物被美國、歐洲等多個國家和地區批准上市用於治療癌症,例如Gefitinib(商品名Irresa),Erlotinib(商品名Tarceva),Lapatinib(商品名Tykerb)等。隨著生物機理的研究、醫學診斷和腫瘤治療水準的不斷提高,對增生類疾病,尤其是腫瘤的治療趨向於細化、靶向化和病人個體化。因此開發療效明確、靶向性高的抗增生類疾病和癌症的化合物仍然是臨床應用所急需。

像本發明所描述的,本發明的化合物可以任選地被一個或多個取代基所取代,如上面的通式化合物,或者像實施例裡面特殊的例子、子類、和本發明所包含的一類化合物。應瞭解“任選取代的”這個術語與“取代或非取代的”這個術語可以交換使用。一般而言,術語“任選地”不論是否位於術語“取代的”之前,表示所給結構中的一個或多個氫原子被具體取代基所取代。除非其他方面表明,一個任選的取代基團可以有一個取代基在基團各個可取代的位置進行取代。當所給出的結構式中不只一個位置能被選自具體基團的一個或多個取代基所取代,那麼取代基可以相同或不同地在各個位置取代。其中所述的取代基可以是,但並不限於,羥基,胺基,鹵素,氰基,芳基,雜芳基,烷氧基,烷基,烯基,炔基,雜環基,巰基,硝基,芳氧基等等。

“可選”代表隨後所描述的事件或環境可以但不必發生。
“藥物組合物”表示一種或多種本文所述化合物或其藥學上可以接受的鹽或前藥與其他化合物組成的混合物,其他組分例如生理學或藥學可接受的載體或賦形劑。藥物組合物的目的是促進化合物對生物的給藥。
除非其他方面表明,本發明所描述的結構式包括所有的同分異構形式(如對應異構、非對應異構、和幾何異構(或結構異構)):例如含有不對稱中心的R、S構型,雙鍵的(Z)、(E)異構體,和(Z)、(E)的結構異構體。因此,本發明的化合物的單個立體化學異構體或其對應異構體,非對應異構體,或幾何異構體(或結構異構體)的混合物都屬於本發明的範圍。
本發明所使用的術語“互變異構體”或“互變異構形式”
表示具有不同能量的結構同分異構體可以越過低能壘,從而互相轉化。譬如,質子互變異構體(即質子移變)包括通過質子遷移進行互變,如酮-烯醇式互變和亞胺-烯胺同分異構化作用。化合價互變異構體包括通過一些成鍵電子重組而進行互變。
除非其他方面表明,本發明的化合物的所有互變異構形式都包含在本發明的範圍之內。
本發明所使用的術語“前藥”,代表一個化合物在體內轉化為式(I)所示的化合物。這樣的轉化受前體藥物在血液中水解或在血液或組織中經酶轉化為母體結構的影響。

本發明的化合物可以包含不對稱中心或手性中心,因此存在不同的立體異構體。本發明的化合物所有的立體異構形式,包括但絕不限於非對應體、對應異構體、阻轉異構體、和它們的混合物,如外消旋混合物,組成了本發明的一部分。很多有機化合物都以光學活性形式存在,即它們有能力旋轉平面偏振光的平面。在描述光學活性化合物時,首碼D、L或R、S用來表示分子手性中心的絕對構型。首碼d、l或(+)、(-)用來命名化合物平面偏振光旋轉的
符號,(-)或l是指化合物是左旋的,首碼(+)或d是指化合物是右旋的。這些立體異構體的化學結構是相同的,但是它們的立體結構不一樣。特定的立體異構體可以是對應體,異構體的混合物通常稱為對應異構體混合物。50:50的對應體混合物被稱為外消旋混合物或外消旋體,這可能導致化學反應過程中沒有立體選擇性或立體定向性。術語“外消旋混合物”和“外消旋體”是指等莫耳的兩個對應異構體的混合物,缺乏光學活性。
術語“互變異構體”或“互變異構的形式”是指不同能量的結構的同分異構體可以通過低能壘互相轉化。例如質子互變異構體(即質子移變的互變異構體)包括通過質子遷移的互變,如酮式-烯醇式和亞胺-烯胺的同分異構化作用。原子價(化合價)互變異構體包括重組成鍵電子的互變。
