Compound (SMILES): CN(C)CCc1ccc(-c2c(O)ccc3[nH]c(=O)c4sccc4c23)cc1F
InChIKey: QTBDIELUWFNQIF-UHFFFAOYSA-N
Target: Serine/threonine-protein kinase Nek1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q96PY6
Assay: Kinase Assay: PBK activity was determined in the presence or absence of compounds using fluorescein isothiocyanate-labeled (FITC-labeled) histone H3 peptide as a substrate. The extent of FITC-labeled histone H3 peptide phosphorylation was measured by immobilized metal ion affinity-based fluorescence polarization (IMAP) technology (Sportsman J R, et al., Assay Drug Dev. Technol. 2: 205-14, 2004) using IMAP FP Progressive Binding System (Molecular Devices Corporation). Test compounds were dissolved in DMSO at 12.5 mM and then serially diluted as the DMSO concentration in the assays to be 1%. The serially diluted compounds, 0.8 ng/micro-L PBK (Carna Biosciences) and 100 nM FITC-labeled histone H3 peptide were reacted in a reaction buffer (20 mM HEPES, 0.01% Tween-20, 0.3 mM MgCl2, 2 mM dithiothreitol, 50 micro-M ATP, pH 7.4) at room temperature for 1 hour. The reaction was stopped by the addition of three fold assay volume of progressive binding solution. Following 0.5 hour incubation at room temperature.

UniProt: P43235
Assay: Inhibition Assay of Human Cathepsin K: Materials: Microtiterplates (Optiplate-384 F were purchased from PerkinElmer (Prod. No. 6007270). The substrate Z-Gly-Pro-Arg-AMC was from Biomol (Prod.-No. P-142). L-Cysteine (Prod. No. 168149) was from Sigma. Sodium acetate was from Merck (Prod.-No. 6268.0250), EDTA was from Fluka (Prod.-No. 03680). The inhibitor E-64 was purchased from Sigma (Prod.-No. E3132). The recombinant human Cathepsin K proenzyme was purchased from Biomol (Prod. No. SE-367). All other materials were of highest grade commercially available. The following buffers were used: Activation buffer: 32.5 mM sodium acetate, adjusted to pH 3.5 with HCl; Assay buffer: 150 mM sodium acetate, 4 mM EDTA, 20 mM L-Cysteine, adjusted to pH 5.5 with HCl, Assay conditions: To activate the proenzyme, 5 μl procathepsin K were mixed with 1 ul activation buffer, and incubated at room temperature for 30 min. 5 μL test compound (final concentration 0.1 nM to 100 μM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 uL of Cathepsin K in assay buffer (final concentration 2 ng/μL) and incubated for 10 min. Then 5 μL of substrate in assay buffer (final concentration 12.5 μM) were added. The plates were then incubated at room temperature for 60 min. Then, the reaction was stopped by adding 10 μL of E64 in assay buffer (final concentration 1 μM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm). Each assay microtiter plate contains wells with vehicle controls (1% DMSO in bidest) as reference for non-inhibited enzyme activity (100% Ctl; high values) and wells with inhibitor (E64 in bidest+1% DMSO, final concentration 1 μM) as controls for background fluorescence (0% Ctl; low values). The analysis of the data was performed by calculating the percentage of fluorescence in the presence of test compound in comparison to the fluorescence of the vehicle control after subtracting the background fluorescence: (RFU(sample)−RFU(background))*100/(RFU(control)−RFU(background)).

Assay: Inhibition Assay of Human Cathepsin K: Materials: Microtiterplates (Optiplate-384 F were purchased from PerkinElmer (Prod. No. 6007270). The substrate Z-Gly-Pro-Arg-AMC was from Biomol (Prod.-No. P-142). L-Cysteine (Prod. No. 168149) was from Sigma. Sodium acetate was from Merck (Prod.-No. 6268.0250), EDTA was from Fluka (Prod.-No. 03680). The inhibitor E-64 was purchased from Sigma (Prod.-No. E3132). The recombinant human Cathepsin K proenzyme was purchased from Biomol (Prod. No. SE-367). All other materials were of highest grade commercially available. The following buffers were used: Activation buffer: 32.5 mM sodium acetate, adjusted to pH 3.5 with HCl; Assay buffer: 150 mM sodium acetate, 4 mM EDTA, 20 mM L-Cysteine, adjusted to pH 5.5 with HCl, Assay conditions: To activate the proenzyme, 5 μl procathepsin K were mixed with 1 ul activation buffer, and incubated at room temperature for 30 min. 5 μL test compound (final concentration 0.1 nM to 100 μM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 uL of Cathepsin K in assay buffer (final concentration 2 ng/μL) and incubated for 10 min. Then 5 μL of substrate in assay buffer (final concentration 12.5 μM) were added. The plates were then incubated at room temperature for 60 min. Then, the reaction was stopped by adding 10 μL of E64 in assay buffer (final concentration 1 μM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm). Each assay microtiter plate contains wells with vehicle controls (1% DMSO in bidest) as reference for non-inhibited enzyme activity (100% Ctl; high values) and wells with inhibitor (E64 in bidest+1% DMSO, final concentration 1 μM) as controls for background fluorescence (0% Ctl; low values). The analysis of the data was performed by calculating the percentage of fluorescence in the presence of test compound in comparison to the fluorescence of the vehicle control after subtracting the background fluorescence: (RFU(sample)−RFU(background))*100/(RFU(control)−RFU(background)).

The recombinant human Cathepsin K proenzyme was purchased from Biomol (Prod. No. SE-367). All other materials were of highest grade commercially available. The following buffers were used: Activation buffer: 32.5 mM sodium acetate, adjusted to pH 3.5 with HCl; Assay buffer: 150 mM sodium acetate, 4 mM EDTA, 20 mM L-Cysteine, adjusted to pH 5.5 with HCl, Assay conditions: To activate the proenzyme, 5 μl procathepsin K were mixed with 1 ul activation buffer, and incubated at room temperature for 30 min. 5 μL test compound (final concentration 0.1 nM to 100 μM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 uL of Cathepsin K in assay buffer (final concentration 2 ng/μL) and incubated for 10 min. Then 5 μL of substrate in assay buffer (final concentration 12.5 μM) were added. The plates were then incubated at room temperature for 60 min. Then, the reaction was stopped by adding 10 μL of E64 in assay buffer (final concentration 1 μM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm). Each assay microtiter plate contains wells with vehicle controls (1% DMSO in bidest) as reference for non-inhibited enzyme activity (100% Ctl; high values) and wells with inhibitor (E64 in bidest+1% DMSO, final concentration 1 μM) as controls for background fluorescence (0% Ctl; low values). The analysis of the data was performed by calculating the percentage of fluorescence in the presence of test compound in comparison to the fluorescence of the vehicle control after subtracting the background fluorescence: (RFU(sample)−RFU(background))*100/(RFU(control)−RFU(background)).

Compound (SMILES): CN1CCN(C(=O)c2cccc(-c3ccc(C[C@@H](C#N)NC(=O)[C@H]4N[C@@H]5CC[C@H]4C5)c(F)c3)c2)CC1
InChIKey: VFHWVMMVSYURFG-YUZJIJRXSA-N
Target: Dipeptidyl peptidase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: P53634
Assay: Inhibition Assay: The recombinant human DPPI was diluted in TAGZyme buffer to 1 U/ml (38.1 ug/ml, respectively), and then activated by mixing in a 1:2 ratio with a Cysteamine aqueous solution (2 mM) and incubating for 5 min at room temperature.Five uL test compound (final concentration 0.1 nM to 100 uM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 uL of DPPI in MES buffer (final concentration 0.0125 ng/uL) and incubated for 10 min. Then, 5 uL of substrate in MES buffer (final concentration 50 uM) were added. The microtiter plates were then incubated at room temperature for 30 min. Then, the reaction was stopped by adding 10 uL of Gly-Phe-DMK in MES-buffer (final concentration 1 uM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm) or an Envision Fluorescence Reader (Ex 355 nm, Em 460 nm).
