- Iminothiadiazine Dioxide Compounds as BACE Inhibitors, Compositions and Their Use
-
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 R1, R2, R3, R4, R5, R9, ring A, ring B, m, n, p, -L1-, -L2-, and -L3- 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.

- PERFLUORINATED 5,6-DIHYDRO-4H-1,3-OXAZIN-2-AMINE COMPOUNDS AS BETA-SECRETASE INHIBITORS AND METHODS OF USE
-
The present invention provides a new class of compounds useful for the modulation of beta-secretase enzyme (BACE) activity. The compounds have a general Formula I: wherein variables A4, A5, A6, A8, each of R1 and R2, R3 and R7 of Formula I, independently, are defined herein. The invention also provides pharmaceutical compositions comprising the compounds, and corresponding uses of the compounds and compositions for treatment of disorders and/or conditions related to A-beta plaque formation and deposition, resulting from the biological activity of BACE. Such BACE mediated disorders include, for example, Alzheimer's Disease, cognitive deficits, cognitive impairments, schizophrenia and other central nervous system conditions. The invention further provides compounds of Formulas II and III, and sub-formula embodiments thereof, intermediates and processes and methods useful for the preparation of compounds of Formulas I-III.
