Synthesis and evaluation of a new class of tertiary alcohol based BACE-1 inhibitors

摘要

BACE-1 has emerged as one of the best characterized targets for future Alzheimer therapy. In accordance with the successful identification of masked inhibitors of HIV-1 protease, we envisioned that tert-alcohol containing transition-state mimicking structures would also be worthwhile evaluating as BACE-1 inhibitors. Twelve novel inhibitors were prepared via synthetic routes using epoxyalcohol derivates as key intermediates. The best synthesized tert-hydroxy inhibitor exhibited a BACE-1 IC50 value of 0.38 mu M.
