are as defined herein, and pharmaceutical compositions thereof. The present invention also provides methods of inhibiting proteases, more specifically aspartyl proteases. In certain embodiments, compounds inhibit BACE (&bgr;-site APP-cleaving enzyme), and thus are useful in the treatment or prevention of a disease characterized by &bgr;-amyloid deposits in the brain (including, but not limited to, Alzheimer's Disease). The present invention also provides methods for preparing compounds of the invention.
本发明提供具有以下公式的化合物:1其中R1、R′、R2、R3、R3′、R4、X1、X2和X3如本文所定义,以及其药物组合物。本发明还提供抑制蛋白酶的方法,更具体地是抑制天冬氨酸蛋白酶。在某些实施方式中,这些化合物抑制BACE(β-APP剪切酶),因此在治疗或预防大脑中存在β-淀粉样沉积的疾病(包括但不限于阿尔茨海默病)方面是有用的。本发明还提供制备本发明化合物的方法。
