γ-Secretase modulators: current status and future directions.

This chapter reviews the current status of γ-secretase modulators, highlighting key compounds by each company involved in the area. The review focuses on the three main chemotypes: acids, imidazoles and related derivatives and natural products. A section on chemical biology and ligand-binding site elucidation studies is also included. The primary source of information is drawn from peer reviewed literature as this permits analysis of PK-PD relationships and subsequent comment. Discussion of the patent literature is included for completeness. From this analysis, the key issues and challenges in the area are highlighted. The review concludes with a summary of the clinical development status and comment on future prospects of the field.
