    In its many embodiments, the present invention provides certain iminothiadiazine dioxide compounds, including compounds Formula (I): and include stereoisomers thereof, and pharmaceutically acceptable salts of said compounds stereoisomers, wherein each of R 1 , R 2 , R 3 , R 4 , R 5 , R 9 , ring A, ring B, m, n, p, -L 1 -, -L 2 -, and -L 3 - is selected independently and as defined herein. The novel iminothiadiazine dioxide compounds of the invention have surprisingly been found to exhibit properties which are expected to render them advantageous as BACE inhibitors and/or for the treatment and prevention of various pathologies related to β-amyloid (“Aβ”) production. Pharmaceutical compositions comprising one or more such compounds (alone and in combination with one or more other active agents), and methods for their preparation and use in treating pathologies associated with amyloid beta (Aβ) protein, including Alzheimer's disease, are also disclosed.
    本发明提供了多种形式的亚氨基噻二唑二氧化物化合物,包括公式(I)的化合物: 包括它们的立体异构体,以及所述立体异构体的药用可接受盐,其中R1、R2、R3、R4、R5、R9、环A、环B、m、n、p、-L1-、-L2-和-L3-都是独立选择且按本文定义。发明的新型亚氨基噻二唑二氧化物化合物出人意料地被发现具有预期的特性,使其作为BACE抑制剂以及/或用于治疗和预防与β-淀粉样蛋白(“Aβ”)生成相关的各种病理学具有优势。还公开了包含一个或多个此类化合物(单独使用和与一个或多个其他活性成分组合使用)的药物组合物,以及它们的制备方法和用于治疗与淀粉样β(Aβ)蛋白相关的病理学,包括阿尔茨海默病的方法。
