Assay: In Vitro Enzymatic BACE FRET Assay: The assay buffer used in this screen is 0.05 M acetate, pH 4.2, 10% DMSO final, 100 uM genapol (which is a nonionic detergent, below its Critical Micelle Concentration). The Beta Secretase enzyme (0.2 nM) is pre-incubated for one hour with inhibitors, typically in about 1 uL of DMSO according to a serial dilution, are added thereto. This assay is effectively started by the addition of FRET substrate (50 nM) and the combination is incubated for one hour.

The FRET substrate is a peptide with commercially available fluorophore and quencher, on opposite sides of the BACE cleavage site. Proteolytic cleavage of the FRET substrate releases quenching of fluorescence (excitation 488 nm and emission 425 nm).

Assay: Fluorescence Polarization (FP) Assay: Fluorescent polarization experiments were performed as follows. Briefly, the fluorescence polarization experiments were read on an Ultra Evolution 384-well plate reader (Tecan) with the 485 nm excitation and 535 nm emission filters. The fluorescence intensities parallel (Intparallel) and perpendicular (Intperpedicular) to the plane of excitation were measured in parallel perpendicular black 384-well NBS assay plates (Corning) at room temperature (20° C). The background fluorescence intensities of blank samples containing the references buffer were subtracted and steady-state fluorescence polarization was calculated using the equation: P=(Intparallel Gintperpendicular)/(Intparallel+Gintperpendicular), and the correction factor G (G=0.998 determined empirically) was introduced to eliminate differences in the transmission of vertically and horizontally polarized light. All fluorescence polarization values were expressed in millipolarization units (mP).

Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used.

Assay: Cellular Enzyme Assay: The expression plasmids contains the ORF for either human/cyno CYP11B1 or CYP11B2 under the control of a suitable promoter (CMV-promoter) and a suitable resistance marker (neomycin). Using standard techniques the expression plasmid is transfected into G-402 cells and these cells are then selected for expressing the given resistance markers. Individual cell-clones are then selected and assessed for displaying the desired enzymatic activity using 11-Deoxycorticosterone (Cyp11B2) or 11-Deoxycortisol (Cyp11B1) as a substrate. G-402 cells expressing CYP11 constructs were established as described above and maintained in McCoy's 5a Medium Modified, ATCC Catalog No. 30-2007 containing 10% FCS and 400 μg/ml G418 (Geneticin) at 37° C. under an atmosphere of 5% CO2/95% air. Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 μM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

UniProt: P56817
Assay: HTRF FRET Assay: A homogeneous time-resolved FRET assay can be used to determine IC50 values for inhibitors of the soluble human BACE1 catalytic domain. This assay monitors the increase of 620 nm fluorescence that resulted from BACE1 cleavage of an APPswedish APPswe mutant peptide FRET substrate (QSY7-EISEVNLDAEFC-Europium-amide). This substrate contains an N-terminal QSY7 moiety that serves as a quencher of the C-terminal Europium fluorophore (620 nm Em). In the absence of enzyme activity, 620 nm fluorescence is low in the assay and increased linearly over 3 hours in the presence of uninhibited BACE1 enzyme Inhibition of BACE1 cleavage of the QSY7-APPswe-Eu substrate by inhibitors is manifested as a suppression of 620 nm fluorescence.Varying concentrations of inhibitors at 3x the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 ul) for 30 minutes at 30° C. in reaction buffer containing 20 mM Na-Acetate pH 5.0, 10% glycerol.

Assay: Lantha Screen Technology Assay: LRRK2 kinase activity was measured using Lantha Screen technology from Invitrogen. GST-tagged truncated LRRK2 from Invitrogen (Cat # PV4874) was incubated with a fluorescein-labeled peptide substrate based upon ezrin/radixin/moesin (ERM), also known as LRRKtide (Invitrogen cat #PR8976A), in the presence of a dose response of compound. Upon completion, the assay was stopped and detected with a terbium labeled anti-phospho-ERM antibody (Invitrogen, cat #PR8975A). The assay was carried out under the following protocol: 3 uL of a working solution of substrate (233 nM LRRKtide, 117 uM ATP) prepared in assay buffer (50 mM HEEPES, pH 7.5, 3 mM MgCl2, with 2 mM DTT and 0.01% Brij35 added fresh) was added to a low volume Greiner 384-well plate. The compound dose response was prepared by diluting compound to a top concentration of 3.16 mM in 100% DMSO and serial diluted by half-log in DMSO 11 times. Aliquots (3.5 uL) of the 100% DMSO dose response were mixed with 46.5 uL water.
