Title:

Beta-secretase (BACE-1) inhibitors: accounting for 10s loop flexibility using rigid active sites.

Abstract:

BACE-1 is a flexible enzyme with experimentally determined motion in the flap region, the catalytic aspartates, and the 10s loop. Four in-house crystallographically determined complexes of tertiary carbinamine inhibitors revealed 10s loop motion in the S(3) pocket. These X-ray structures were used to correlate K(i) values, which span over five orders of magnitude, with the calculated interaction energy, using the Merck Molecular Force Field for a series of 19 tertiary carbinamine inhibitors.
