已知其為小分子受體酪胺酸激酶抑制劑,抑制表皮生長因數受體(EGFR)和人表皮因數受體2(ERBB2)。其可以與細胞內EGFR和ERBB2的激酶區的ATP結合位點共價結合,阻止腫瘤細胞內EGFR和ERBB2的同質和異質二聚體形成,抑制其自身的磷酸化,阻斷下游信號通路的啟動,從而抑制腫瘤細胞生長。臨床上可用於胃癌、肺癌、乳腺癌等多種腫瘤的治療。
CN102933574B公開了式I化合物的馬來酸鹽形式,其相對於其他鹽和式I化合物本身在溶解度以及生物利用度和藥物代謝動力學方面更具優勢。
CN103974949B公開了式I化合物二馬來酸鹽的I型結晶。該晶型具有良好的晶型穩定性和化學穩定性,可用於製備治療與EGFR受體酪胺酸激酶或HER-2受體酪胺酸激酶有關的疾病的藥物。

在本發明提供的醫藥組成物的製備方法中,賦形劑中的一種或多種(例如填充劑、崩解劑、黏合劑)可以與潤濕劑以及活性成分一起混合後製粒,然後乾燥;或者在將僅有活性成分與潤濕劑混合製得的顆粒乾燥後加入一種或多種賦形劑;也可以將賦形劑的一部分與活性成分以及潤濕劑一起混合而另一部分在製粒乾燥後加入。較佳地,將填充劑、崩解劑以及黏合劑與活性成分以及潤濕劑一起混
合,然後製粒乾燥,再加入潤滑劑。
本發明還提供了一種醫藥組成物的製備方法,包括:將活性藥物(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-甲基吡咯烷基-2-基)-丙烯醯胺或其藥理學上可接受的鹽與潤濕劑混合,製粒,乾燥,壓片製成片劑或灌裝製成膠囊,其中,該潤濕劑可以是乙醇與水的混合溶劑,該乙醇的含量可以是基於潤濕劑的總重量的50~80%,該醫藥組成物還可以包含:1)2-20wt%的崩解劑,該崩解劑為交聯聚乙烯吡咯烷酮;2)5-80wt%的填充劑,該填充劑選自乳糖和微晶纖維素中的一種或多種;3)0.5-15wt%的黏合劑,該黏合劑選自聚乙烯吡咯烷酮、羥丙基甲基纖維素及羥丙基纖維素中的一種或多種;4)0.5-5wt%的潤滑劑,該潤滑劑選自硬脂酸鎂和滑石粉的一種或多種。
