Abstract

Description
发明背景
如本文描述的提供新的他那普戈特(tanaproget)多晶型II和包含其的组合物。
细胞内受体(IR)形成了一类结构上相关的基因调节物质,被称为“配体依赖性转录因子”。类固醇受体家族是IR家族的一个亚类,包括孕激素受体(PR)、雌激素受体(ER)、雄激素受体(AR)、糖皮质激素受体(GR)和盐皮质激素受体(MR)。
对于PR而言,天然激素或配体是类固醇黄体酮,但也合成了化合物比如甲羟孕酮或左炔诺孕酮作为配体。一旦细胞周围的液体中存在配体,配体就经由被动扩散穿过膜,并与结合IR产生受体/配体复合物。该复合物结合细胞DNA中存在的特定基因启动子。一旦结合DNA,该复合物调节mRNA和由所述基因编码的蛋白质的产生。
将结合IR并模拟天然激素作用的化合物称为激动剂,而抑制所述激素作用的化合物称为拮抗剂。
已知PR激动剂(天然的和合成的)在妇女健康中起重要作用。在计划生育组合物中,典型地在ER激动剂的存在下使用PR激动剂,可选地,它们可以与PR拮抗剂一起使用。ER激动剂用于治疗绝经症状,但已经和子宫的增殖作用联系起来,可导致子宫癌的危险增加。联合给药PR激动剂减少/解除了这种危险。
他那普戈特,5-(4,4-二甲基-2-硫代-1,4-二氢-2H-3,1-苯并噁嗪-6-基)-1-甲基-1H-吡咯-2-甲腈,为一种孕激素受体调节剂,在避孕、激素替代治疗和治疗癌和腺癌、功能异常性出血、子宫肌瘤、子宫内膜异位和多囊卵巢综合征中有效。

在进一步的方面,提供制备包含他那普戈特多晶型II的药物组合物的方法。
在另一个方面,提供从他那普戈特多晶型II制备他那普戈特多晶型I的方法。

晶型I可以从丙酮/水溶剂中在约1、2、3、4、5、6或6天内沉淀。 典型地,晶型I从丙酮/水溶液中约1周后沉淀,使用本领域技术人员已知的技术收集。然而,向晶型I的转化可以在少于1周或者甚至少于1天内完成,取决于在转化期间使用的条件和在转化期间存在的任何环境因素。
在另一个实施方案中,将他那普戈特多晶型II转化成他那普戈特晶型I而没有使用溶剂。典型地,首先将晶型II加热至其熔点,典型地加热至约219至约229℃,更期望地加入至约219至约216℃。使用多种技术实施加热,包括但不限于高温显微术(hot stage microscopy)。一旦晶型II熔化,典型地将液体样品保持在约219℃至约229℃以促进晶型I他那普戈特多晶型物结晶。然后,使用本领域技术人员已知的技术收集晶型I。
如果在219℃至229℃之间在可接受的一段时间内不出现向晶型I的结晶,则慢慢地冷却样品至低于219℃,直到出现结晶。
提供下述实施例用于阐述本发明,但不限制其范围。本领域技术人员应当理解尽管在下述实施例中列出了特定的试剂和条件,但可进行修饰,其包括在本发明的精神和范围内。
