氟班色林的新晶型及其制备方法及其用途 技术领域
本发明涉及[2-(4-(3-三氟甲基-苯基)哌嗪-1-基)乙基]-2,3-二氢-1H-苯并咪唑-2-酮的新型晶体及其制备方法和用途。
背景技术
化合物式1,氟班色林(Flibanserin,[2-(4-(3-三氟甲基-苯基)哌嗪-1-基)乙基]-2,3-二氢-1H-苯并咪唑-2-酮)是美国FDA已经批准的药物,能减少抑制性欲的5-羟色胺,以提高刺激性欲的多巴胺水平,对绝经前妇女性欲低下(HSDD)显示出良好疗效和耐受性。氟班色林对5-HT1A与5-HT2受体具有亲和力,有希望治疗抑郁症、精神分裂症、帕金森症、焦虑症及睡眠障碍,精神异常以及年龄相关的记忆障碍
氟班色林的分子式为C20H21F3N4O,其分子量为390.40。氟班色林的化学结构式如下所示:

化学原料药要成制剂,必须具备良好的纯度、稳定性、理化性质以及可操作性。而这些性质都与药物的结晶形态相关,不同晶型具有不同的理化性质。药物保存的稳定性和提高药物疗效的目的,需要将药物制成晶体的状态。
一种药物可以多种晶型物质状态存在,同一种药物的不同晶型,在体内的溶解和吸收可能不同,从而会对制剂的溶出和释放产生影响。
对药物多晶型的研究,可发现有利于发挥药物作用的药物优势晶型,同时根据晶型的特点确定制剂工艺,有效保证生产的批间药物等效性等。
氟班色林发现的多晶型有以下几种,欧洲专利申请EP-A-526434中报导了氟班色林的盐酸盐。WO2003/014079专利揭示了氟班色林的游离碱的两种晶型,包括氟班色林的游离碱晶型A和晶型B。晶型A以其熔点约161℃特点(由DSC测定,加热速率10K/min),晶型B以其熔点约120℃特点(由DSC测定,加热速率10K/min)。晶型B在压力和机械应力条件下稳定性比较低,不适合制剂开发。晶型A的XRPD图显示晶型A在如下2θ角度具有衍射峰:15.46±0.01,19.14±0.01,19.82±0.01,20.08±0.01,22.63±0.01和24.61±0.01。然而,现有技术中氟班色林晶型A的水中溶解度十分小,不利于药物的溶解和释放,造成生物利用度降低和吸收不稳定。

具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明,但并不用来限制本发明的范围。
实施例1
将1.0g[2-(4-(3-三氟甲基-苯基)哌嗪-1-基)乙基]-2,3-二氢-1H-苯并咪唑-2-酮盐酸盐溶于400ml水中,向其中加入2mg/ml的碳酸钠溶液,析出固体后过滤,得[2-(4-(3-三氟甲基-苯基)哌嗪-1-基)乙基]-2,3-二氢-1H-苯并咪唑-2-酮晶型I。
本专利中X射线粉末衍射,操作和分析步骤如下:
采用Rigaku Ultima IV粉末衍射仪,该仪器采用Cu-Kα照射(40kV,40mA),于室温下使用D/tex Ultra检测器进行。扫描范围在2θ区间自3°至45°,扫描速度为20°/分钟
由包括以下的多种因素产生与这类X射线粉末衍射分析结果相关 的测量差异:(a)样品制备物(例如样品高度)中的误差,(b)仪器误差,(c)校准差异,(d)操作人员误差(包括在测定峰位置时出现的误差),和(e)物质的性质(例如优选的定向误差)。校准误差和样品高度误差经常导致所有峰在相同方向中的位移。当使用平的支架时,样品高度的小差异将导致XRPD峰位置的大位移。系统研究显示1mm的样品高度差异可以导致高至1°的2θ的峰位移。可以从X射线衍射图鉴定这些位移,并且可以通过针对所述位移进行补偿(将系统校准因子用于所有峰位置值)或再校准仪器消除所述位移。如上所述,通过应用系统校准因子使峰位置一致,可校正来自不同仪器的测量误差。
