The present invention relates to novel compounds of formula I and therapeutically acceptable salts thereof, their pharmaceutical compositions, processes for making them and their use as therapeutic methods for treatment and/or prevention of various diseases. In particular the invention relates to compounds, which inhibit the Aβ40 and Aβ42 production, increase the Aβ37 and Aβ38 production and maintain the Notch signaling and will be used for treatment and/or prevention of Aβ-related pathologies such as Alzheimer's disease, Downs syndrome and β-amyloid angiopathy, such as but not limited to cerebral amyloid angiopathy, hereditary cerebral hemorrhage, disorders associated with cognitive impairment, such as but not limited to MCI (“mild cognitive impairment”), Alzheimer's disease, memory loss, attention deficit symptoms associated with Alzheimer's disease, neurodegeneration associated with diseases such as Alzheimer's disease or dementia including dementia of mixed vascular and degenerative origin, pre-senile dementia, senile dementia and dementia associated with Parkinson's disease, progressive supranuclear palsy or cortical basal degeneration.
本发明涉及公式I的新化合物及其治疗上可接受的盐,它们的制药组合物,制备它们的方法以及它们作为治疗和/或预防各种疾病的治疗方法。特别是本发明涉及抑制Aβ40和Aβ42产生,增加Aβ37和Aβ38产生并维持Notch信号的化合物,并将其用于治疗和/或预防与Aβ相关的病理,如阿尔茨海默病,唐氏综合症和β-淀粉样蛋白血管病,如但不限于脑淀粉样血管病,遗传性脑出血,与认知功能障碍相关的疾病,如但不限于轻度认知障碍(MCI),阿尔茨海默病,记忆力丧失,与阿尔茨海默病相关的注意力缺陷症状,与阿尔茨海默病或痴呆症相关的神经退行性疾病,包括混合性血管性和退行性起源的痴呆,早老性痴呆,老年性痴呆以及与帕金森病,进行性核上性麻痹或皮层基底节变性相关的痴呆。
