Assay Method Information

Assay Name:  Inhibition Assay
Description:  The potencies of compounds were determined by measurement of their inhibition of memapsin 2 catalytic activity toward a fluorescent substrate. Kinetic inhibition experiments were performed using the procedure as described in Ermolieff, et al. Biochemistry 39:12450-12456 (2000), the teachings of which are incorporated hereby in their entirety. Briefly, assays were performed at pH 4, 37° C., by pre-incubation of memapsin 2 enzyme with compound for 20 minutes. Activity measure was initiated by addition of a fluorogenic substrate FS-2 (Bachem Americas, Torrance, Calif.).
