Through these efforts compound 2 was identified as a potent (cell IC50 = 15nM) BACE inhibitor with acceptable ADME properties. When tested in vivo, compound 2 demonstrated a significant reduction of brain and cerebral spinal fluid (CSF) Abeta40 levels (46% and 66%, respectively) in a rat pharmacodynamic study and thus represents a suitable starting point for the further development of in vivo efficacious compounds for the treatment of Alzheimer's disease. | ||
