Description
本发明涉及一种酪氨酸激酶抑制剂的苹果酸盐的结晶形态,特别是5-(2-二乙胺基-乙基)-2-(5-氟-2-氧代-1,2-二氢-吲哚-3-亚基-甲基)-1,5,6,7-四氢-吡咯[3,2-c]吡啶-4-酮L-苹果酸盐的I型结晶。
近年来,随着分子生物学技术的进展和从细胞受体与增殖调控的分子水平对肿瘤发病机制认识的进一步深入,针对细胞受体、关键基因和调控分子为靶点的治疗开始进入临床,人们称之为“分子靶向治疗”。这些领域包括具有靶向性的表皮生长因子受体(EGFR)阻滞剂、针对某些特定细胞标志物的单克隆抗体、针对某些癌基因和癌的细胞遗传学标志的药物、抗肿瘤血管生成的药物、抗肿瘤疫苗和基因治疗等。
首先进入临床的酪氨酸激酶抑制剂(TKIs)的抗肿瘤作用机制可能通过以下途径实现:抑制肿瘤细胞的损伤修复、使细胞分裂阻滞在G1期、诱导和维持细胞凋亡、抗新生血管形成等。EGFR过度表达常预示病人预后差、转移快、对化疗药物抗拒、激素耐药、生存期较短等。TKIs还可通过下调肿瘤细胞的血管生成因子以及抑制EGFR对肿瘤血管内皮细胞的信号传导,EGFR和血管内皮生长因子受体(VEGFR)两种信号传导通路的“交叉对话”,为临床同时抑制这两种传导通路提供了合理的依据。临床试验结果显示,多靶点抑制剂在治疗方面优于单靶点抑制剂,多靶点联合阻断信号传导是肿瘤治疗和药物开发新的发展方向。
到目前为止,美国FDA批准3种多靶点TKIs上市,如:索拉非尼(sorafenib)、凡德他尼(vandetanib)和Sunitinib(Sutent,SU-11248),其中Sunitinib于2006年1月份批准上市,治疗GIST和晚期肾癌。由于目前临床上除了伊马替尼外,没有治疗晚期GIST的药物,治疗肾癌的药物也很少,所以Sunitinib的结果令人鼓舞。WO2007085188公开了一种与Sunitinib类似的化合物,如下式(I)所示,其可能更好地应
用于上述肿瘤的治疗。
本领域技术人员知道,药用的活性成分的晶型结构往往影响到该药物的化学稳定性,结晶条件及储存条件的不同有可能导致化合物的晶型结构的变化,有时还会伴随着产生其他形态的晶型。一般来说,无定型的药物产品没有规则的晶型结构,往往具有其它缺陷,比如产物稳定性较差,析晶较细,过滤较难,易结块,流动性差等。因此,改善上述产物的各方面性质是很有必要的,我们需要深入研究找到晶型纯度较高并且具备良好化学稳定的新晶型。
