Abstract
本发明提供多发性硬化症的治疗剂或预防剂,其含有N‑[2‑(6,6‑二甲基‑4,5,6,7‑四氢‑1H‑吲唑‑3‑基)‑1H‑吲哚‑6‑基]‑N‑甲基‑(2S)‑2‑(吗啉‑4‑基)丙酰胺或其药学上可接受的盐。
Description
[技术领域]
本发明涉及N-[2-(6,6-二甲基-4,5,6,7-四氢-1H-吲唑-3-基)-1H-吲哚-6-基]-N-甲基-(2S)-2-(吗啉-4-基)丙酰胺(下文称为化合物A)或其药学上可接受的盐的新型制药用途。更特别地,本发明涉及多发性硬化症的治疗剂或预防剂、防止多发性硬化症复发的药剂和抑制多发性硬化症的身体障碍进展的药剂,它们各自含有化合物A或其药学上可接受的盐。
[背景技术]
多发性硬化症(MS)是中枢神经系统的一种炎性脱髓鞘病,其伴随着反复复发和缓解,并以炎性脱髓鞘病变的时间和空间多发性为特征。脱髓鞘可造成锥体束、小脑、脑干、感觉、膀胱、直肠、视觉和精神功能的各种障碍,其中症状和严重度可随脱髓鞘的位置和程度而变。主要表现是虚弱感、共济失调和感觉神经病,并且如排尿和排便障碍、精神和记忆障碍之类的症状可表示为病理进展(非专利文献1)。
MS基于临床过程分类为以下三种疾病类型(非专利文献2)。在复发缓解型MS(RRMS)中,反复出现急性加重(复发)和随后缓解。原发进展型MS(PPMS)是一种进展型MS,其从发展早期就没有表现出明显的复发。继发进展型MS(SPMS)是由RRMS过渡到没有明显复发的进展型MS造成的疾病类型。
实验性自身免疫性脑脊髓炎(EAE)模型通常被视为与MS相关的动物模型(非专利文献3)。已经报道了诱导型T细胞激酶(ITK)敲除小鼠在使用EAE模型小鼠的实验中表现出疾病严重度的降低(非专利文献4)。但是,没有描述用低分子ITK抑制剂治疗MS。
在专利文献1和专利文献2中描述了化合物A,N-[2-(6,6-二甲基-4,5,6,7-四氢-1H-吲唑-3-基)-1H-吲哚-6-基]-N-甲基-(2S)-2-(吗啉-4-基)丙酰胺,及其药学上可接受的盐。专利文献1描述了化合物A具有ITK抑制活性并可以是对治疗或预防如类风湿性关节炎、炎性肠病之类的疾病、抑制移植排斥等有效的药物。专利文献2描述了化合物A和其药学上可接受的盐的制备方法。
