Definitions

  • the present invention relates to the field of medicinal chemistry, and in particular to a solid form of an N-substituted phenylsulfonamide compound.
  • TRPA1 is a member of the TRP ion channel superfamily and the only member of the TRPA subfamily. It is a non-selective cation channel that is permeable to Na + , K + , Ca2+ and Mg2 + .
  • TRPA1 is mainly distributed in the primary sensory neurons of the dorsal root ganglion (DRG), trigeminal nerve (TG) and vagus nerve (VG). From the perspective of the human body system in which it is distributed, TRPA1 is highly expressed in the peripheral nervous system, respiratory system, gastrointestinal system and urinary system. When these organs and tissues have functional abnormalities, the expression and function of TRPA1 channels are usually also abnormal.
  • TRPA1 can convert cold stimulation, chemical stimulation and mechanical stimulation into inward currents, trigger a series of physiological functions, and participate in the formation of multiple pain sensations. Inflammatory pain is a common problem of certain chronic diseases, and there is still a lack of effective treatment methods in clinical practice. Animal experimental studies have shown that TRPA1 participates in inflammatory reactions and plays an important role in inflammatory pain. By using TRPA1-specific blockers, the inflammatory pain response of rats can be significantly reduced. From the current research, TRPA1 plays an important role in the occurrence of asthma and cough. Compounds that induce asthma and cough, whether they are endogenous factors or exogenous factors, can activate TRPA1. TRPA1 antagonists can alleviate asthma symptoms and block airway hyperresponsiveness.
  • TRPA1 is involved in the regulation of visceral hypersensitivity and plays an important role in visceral pain.
  • Neurogenic pain is a pain syndrome caused by damage or disease of the central or peripheral nervous system, mainly manifested as hyperalgesia, abnormal pain sensitivity and spontaneous pain.
  • TRPA1 channels play an important role in different neurogenic pain, such as diabetic neuropathy and neuropathy caused by chemotherapy drugs.
  • TRPA1 also plays a mediating role in pain such as toothache and migraine.
  • the administration of TRPA1 antagonists can significantly relieve the occurrence of pain symptoms.
  • TRPA1 is widely distributed and expressed in the human body. In addition to the physiological functions involved in the above, the development of TRPA1 inhibitors has also been reported to involve inflammatory bowel disease, chronic obstructive pulmonary disease, antitussive, antipruritic, allergic rhinitis, ear diseases, anti-diabetes, urinary incontinence, etc. TRPA1 is a new target for the treatment of multiple diseases that has been confirmed.
  • N-substituted phenylsulfonamide compounds exhibit potent inflammatory bowel disease therapeutic and analgesic effects by inhibiting transient receptor potential ankyrin 1 (TRPA1), and also have excellent safety characteristics.

Description

N-取代苯基磺酰胺类化合物的固体形式 技术领域
本发明涉及药物化学领域，具体地涉及一种N-取代苯基磺酰胺类化合物的固体形式。
背景技术
TRPA1是TRP离子通道超家族中的一员，TRPA亚家族的唯一成员，属于非选择性阳离子通道，可通透Na+，K+，Ca2+和Mg2+。TRPA1主要分布在背根神经(DRG)、三叉神经(TG)和迷走神经(VG)的初级感觉神经元上。从分布的人体系统来看，TRPA1高表达在外周神经系统、呼吸系统、胃肠系统和泌尿系统，当这些器官组织出现功能异常时，TRPA1通道的表达和功能通常也同步发生异常。TRPA1可以将冷刺激、化学刺激以及机械刺激转化为内向电流，引发一系列生理功能，并参与多种痛觉的形成。炎性痛是某些慢性疾病的共同困扰，临床上尚缺乏很有效的治疗手段。动物实验研究显示，TRPA1参与炎性反应，并在炎性疼痛中发挥重要作用，通过使用TRPA1特异性阻断剂，可以明显减轻大鼠炎性疼痛反应。从目前的研究来看，TRPA1在哮喘和咳嗽的发生中扮演重要的作用，诱导哮喘与咳嗽的化合物，无论是细胞内源因子，还是外源因子，都能激活TRPA1。TRPA1的拮抗剂能够减轻哮喘症状，能阻断气道高反应性。通过不同的内脏高敏感动物模型如结肠炎、直结肠扩张或应激，证实TRPA1参与内脏高敏感的调控，在内脏痛中发挥重要作用。神经源性疼痛是由中枢或外周神经系统损伤或者疾病引起的疼痛综合征，主要表现为痛觉过敏、异常痛敏和自发性疼痛等。近年来越来越多的研究显示，TRPA1通道在不同的神经源性疼痛中起到重要作用，例如糖尿病性神经病变和化疗药引起的神经病变等。最近研究还表明，TRPA1在牙痛、偏头痛等疼痛中也有介导作用，通过给予TRPA1的拮抗剂能明显缓解疼痛症状的产生。
TRPA1在人体系统中广泛分布和表达，除以上TRPA1参与的生理功能外，目前已报道的TRPA1抑制剂适应症的开发还涉及到炎症性肠病、慢性阻塞性肺疾病、镇咳、止痒、过敏性鼻炎、耳疾病、抗糖尿病、尿失禁等。TRPA1是已经被证实了的多种疾病治疗的新靶点。
N-取代苯基磺酰胺类化合物，通过抑制瞬时受体电位锚蛋白1(TRPA1)，表现出强效的炎症性肠病治疗药效和镇痛药效，同时具有非常优秀的安全特性。

实施例4：评估实施例制备的部分盐晶型的特性
引湿性
采用动态水分吸附(DVS)仪测试引湿性，结果如图25-30所示，在0％RH～95％RH的吸附曲线上，在25℃/80RH条件下，游离态晶型A的水分吸附量为1.6％，略有引湿性；富马酸盐晶型B的水分吸附量为0.2％，略有引湿性；盐酸盐晶型C的水分吸附量为5.5％，样品有引湿性；硫酸盐晶型D的水分吸附量为1.3％，样品略有引湿性；琥珀酸盐晶型E的水分吸附量为0.6％，样品略有引湿性；苹果酸盐晶型F的水分吸附量为1.4％，样品略有引湿性(参考中国药典2015年版(药物引湿性试验指导原则))。
动态溶解度
测试富马酸晶型B、盐酸盐晶型C、硫酸盐晶型D、琥珀酸晶型E、苹果酸晶型F及游离态晶型A在37℃下在生物溶媒SGF、FaSSIF和水中的动态溶解度。实验中，所有样品在三种溶剂中的固体投料量均为10mg/mL。将样品密封固定在转速为25转/分钟的旋转盘上，并将旋转盘放置于37℃恒温箱中。分别在平衡1、2、4和24小时时间点取样，分离滤液测试HPLC浓度及PH，所得固体测试XRPD。结果如图31所示，可以看出，各盐的晶型物在生物溶媒SGF、FaSSIF和水中溶解度相对于游离态均有明显的提升，起始样品在水和FaSSIF几乎不溶解，而盐晶型的溶解度则可以提升至6-10mg/mL。
固态稳定性
分别称取约10毫克固体加入HPLC小瓶中，瓶口用封口膜封口，膜上扎10个小孔，将小瓶置于25℃/60％RH和40℃/75％RH环境中放置4周，分别于第1周、2周和第4周取样，对样品进行HPLC纯度和XRPD测试。HPLC结果显示，游离态及各盐型样品在对应的条件储存后未见明显纯度变化；XRPD结果显示，游离态及各盐型样品于稳定性测试前后未见明显晶型变化。固体稳定性结果总结如表13所示。
表13


粗略溶解度
于3-mL玻璃瓶中加入对应晶型样品，分步加入纯水(50、50、200及700μL)涡旋、超声振荡助溶，并观察固体样品是否完全溶解。当固体完全溶解或加入纯水量总体积达到1mL后停止加入溶剂。根据加入溶剂体积计算粗略溶解度。
粗略溶解度的测试结果如表14所示，与游离态晶型A相比，各个盐型晶型在纯水中的溶解度均有显著提升。
