Provided are compounds useful for treating diseases associated with a cerebral accumulation of Alzheimer's amyloid, such as Alzheimer's disease. Also provided are methods for screening for such compounds, by measuring capacitative calcium entry in cells which optionally overexpress APP or a fragment thereof. Also provided are methods of treating or reducing the risk of developing β-amyloid production, β-amyloid deposition, β-amyloid neurotoxicity (including abnormal hyperphosphorylation of tau) and microgliosis associated with cerebral accumulation of Alzheimer's amyloid by administering therapeutically effective amounts of compounds which decrease β-amyloid production and capacitative calcium entry in cells. Further provided are methods for diagnosing diseases associated with cerebral accumulation of Alzheimer's amyloid in animals or humans by administering diagnostically effective amounts of compounds which inhibit capacitative calcium entry in cells.
提供了对治疗与阿尔茨海默病相关的脑部淀粉样蛋白沉积疾病(如阿尔茨海默病)有用的化合物。还提供了筛选此类化合物的方法,通过测量细胞中的电容性钙离子入流,该细胞可选择过表达APP或其片段。还提供了通过给予治疗有效量的化合物来治疗或降低β-淀粉样蛋白产生、β-淀粉样蛋白沉积、β-淀粉样蛋白神经毒性(包括tau异常的超磷酸化)和与阿尔茨海默病相关的微胶质细胞病的风险的方法,这些化合物降低细胞中的β-淀粉样蛋白产生和电容性钙离子入流。此外,还提供了通过给予诊断有效量的化合物来诊断动物或人类中与阿尔茨海默病相关的脑部淀粉样蛋白沉积疾病的方法,这些化合物抑制细胞中的电容性钙离子入流。
