| Description: | In brief, the enzyme (29 nM) was incubated with L-alanine-p-nitroanilide (1 mM) in 50 mM HEPES (pH 7.5), 100 mM KCL, 1% DMSO in the absence or presence of a compound of the invention for 1 hour at ambient temperature. Reaction was terminated by addition of acetic acid (1%). Formation of colored nitro-aniline was measured by the increase in absorbance at 405 nm in a Victor 2 plate reader (Wallac). Spontaneous hydrolysis of the substrate was corrected for by subtracting the absorbance of control incubations without enzyme.In embodiments, the compounds of the invention, when tested in this assay, demonstrated the ability to inhibit peptidase activity at IC50 values of less than 100 μM, in some embodiments less than 1 μM, in some embodiments less than 100 nM, in some embodiments less than 75 nM, in some embodiments less than 50 nM, in some embodiments less than 25 nM, in some embodiments less than 10 nM, in some embodiments less than 5 nM. |
