Description
本發明涉及一種酪胺酸激酶抑制劑的二馬來酸鹽的結晶形態,特別是(R,E)-N-(4-(3-氯-4-(吡啶-2-基)甲氧基)-苯基胺基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯啶-2-基)丙烯醯胺二馬來酸鹽的第I型結晶及其製備方法和用途。
近年來我國的腫瘤死亡率呈明顯上升趨勢,癌症嚴重威脅著人們的生命和生活質量,因此尋找高效、低毒的抗腫瘤藥物是當今生命科學中極富挑戰性且意義重大的課題。受體酪胺酸激酶是一類參與訊息傳導的跨膜蛋白,研究表明,超過50%的原位癌基因和癌基因產物都具有酪胺酸激酶活性,它們的異常表達將導致腫瘤發生。酪胺酸激酶抑制劑從2001年開始上市,已成為異軍突起的一類新型抗癌藥。
表皮生長因子受體(EGFR)是受體酪胺酸激
酶家族的一員,表皮生長因子受體路徑在腫瘤發生、發展過程中起非常重要的作用,目前已成為腫瘤治療領域最主要的研究和開發靶點之一。現已經上市的此類藥物有埃羅替尼(erlotinib)、吉非替尼(gefitinib)和拉帕替尼(lapatinb,Tykerb,GW572016),目前尚處於臨床階段的有來那替尼(neratinib)。WO2011029265公開了化合物(R,E)-N-(4-(3-氯-4-(吡啶-2-基)甲氧基)-苯基胺基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯啶-2-基)丙烯醯胺(為表述方便,以下簡稱SHR1258)的製備方法,該藥物分子具有明顯的藥物代謝、藥效優勢。儘管WO2011029265中公開了化合物SHR1258的化學結構和製備方法,但未對其呈鹽的情況進行研究。在中國專利申請案201110062359.8中描述了該化合物的二馬來酸鹽(以下簡稱SHR1258二馬來酸鹽),結構如下:
但是卻沒有進一步研究SHR1258二馬來酸鹽的晶形以及製備方法。本領域技術人員知道,藥用的活性成分的晶形結構往往影響到該藥物的化學穩定性,結晶條件及儲存條件的不同有可能導致化合物的晶形結構的變化,有時還會伴隨著產生其他形態的晶形。一般來說,無定形的藥物產品沒有規則的晶形結構,往往具有其它缺
陷,比如產物穩定性較差,析晶較細,過濾較難,易結塊,流動性差等。因此,改善上述產物的各方面性質是很有必要的,我們需要深入研究找到晶形純度較高並且具備良好化學穩定的新晶形。
本發明的目的是提供一種SHR1258二馬來酸鹽的穩定晶形以及製備該晶形的方法。
我們考察了SHR1258二馬來酸鹽在不同結晶條件下得到的一系列結晶產物,對所得結晶產物進行了X-繞射及DSC檢測,發現SHR1258二馬來酸鹽在常規的結晶條件下,可以得到一種穩定性良好的晶形,我們稱其為第I型結晶。本申請中的第I型結晶的DSC圖譜顯示在130℃附近有熔融吸熱峰,X射線粉末繞射圖譜如第1圖所示,使用Cu-Ka輻射,以2θ角度和晶面間距(d值)表示的X射線粉末繞射圖譜,其中在6.28(14.06)、6.74(13.10)、10.60(8.34)、11.58(7.64)、13.50(6.55)、14.90(5.94)、15.80(5.60)、18.26(4.85)、20.66(4.30)、21.14(4.20)、22.96(3.87)、24.34(3.65)、25.54(3.49)和26.12(3.41)有特徵峰。
本發明製備第I型結晶的方法中,可作為原料使用的SHR1258二馬來酸鹽的存在形態沒有特別限定,可以使用任意晶形或無定形固體,本發明的SHR1258二馬來酸鹽第I型結晶的製備方法為:使用某些低級有機溶劑,較佳為含碳原子數小、同時能夠揮發並可用作為結晶溶劑的醇類、酮類、酯類等極性有機溶劑,或它們的混合
溶液;更佳為異丙醇、丙酮、乙醇、乙酸乙酯、四氫呋喃或它們的混合物,作為SHR1258二馬來酸鹽結晶的重結晶溶劑。析晶時可以用單一溶劑,也可以用選自以上有機溶劑的混合溶劑。
具體的,本發明提供的製備SHR1258二馬來酸鹽第I型結晶的方法包括以下步驟:(1)將SHR1258與馬來酸,或者將SHR1258二馬來酸鹽固體溶解於適量的有機溶劑中,冷卻、析晶;(2)過濾、洗滌、乾燥。
在本發明較佳的實施方案中,步驟(1)中,有機溶劑選自碳原子數小於或等於3的醇類、丙酮、乙酸乙酯、四氫呋喃中的一種或多種。更佳地,有機溶劑選自乙醇、異丙醇、四氫呋喃中的一種或多種。
進一步地,最佳的單一溶劑為異丙醇。
在本發明的一個實施方案中,較佳的混合有機溶劑為乙醇/四氫呋喃的混合溶劑,二者比例沒有特別限制,在本發明較佳的實施方案中,二者體積比為1:1。
重結晶的方法沒有特別限定,可以用通常的重結晶操作方法進行。例如,可以用原料SHR1258二馬來酸鹽在有機溶劑加熱溶解後慢慢冷卻靜置析晶,也可採取攪拌析晶,結晶完成後,經過濾乾燥,即可得到所需要的結晶。需特別說明的是,SHR1258二馬來酸鹽形成穩定的晶形需要具備充分的轉化過程,析晶時溶液的過度飽和往往導致析晶過程過快,容易得到無定形固體或晶形純度
較差的結晶,適當的增大溶劑體積或放慢析晶速度,則有助於得到晶形純度較高的穩定晶形。所濾取的結晶體通常在減壓下,在30至100℃左右,較佳在40至60℃的加熱條件下進行真空乾燥,就能達到去除重結晶溶劑的效果。
通過差示掃描熱分析(DSC)、X-射線繞射圖譜測定,對得到的SHR1258二馬來酸鹽結晶體進行了晶形研究,同時對所得結晶的溶劑殘留進行了檢測。
按照本發明的方法製備的SHR1258二馬來酸鹽結晶不含有或僅含有較低含量的殘留溶劑,符合國家藥典規定的有關醫藥產品殘留溶劑的限量要求,因而本發明的結晶可以較好地作為醫藥活性成分使用。
經研究表明,本發明製備的SHR1258二馬來酸鹽第I型結晶在高溫、高濕的條件下穩定性顯著好於無定形樣品且在研磨、壓力和受熱等條件下,晶形穩定性良好,能夠滿足生產運輸儲存的藥用要求,生產工藝穩定可重複可控,能夠適應於工業化生產。
