Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
UniProt: Q06187
Assay: Recombinant Human BTK Inhibition Assay: The inhibition assays were performed using the generic tyrosine kinase assay kit from C is Bio (HTRF KinEASE-TK #62TK0PEB). The assay is based on the principle of fluorescence resonance energy transfer (FRET) between the Europium Cryptate labeled anti-phosphotyrosine antibody and streptavidin labeled fluorophore, XL-665. In an uninhibited kinase reaction the biotinylated peptide substrate (Tk-Biotin) gets phosphorylated at an intermediate tyrosine site which is captured by anti-phosphotyrosine antibody which eventually acts as a FRET donor. The streptavidin labeled XL-665 binds strongly to the Tk-Biotin substrate and act as a FRET acceptor. The resultant FRET signal is measured at 665 nm. A ratio of this specific fluorescence (665 nm) to the background fluorescence (620 nm), conferred by the free antibody, is directly proportional to the kinase activity. Inhibition of the kinase activity by a pharmacological intervention such as a Btk inhibitor of the present disclosure will result into decreased FRET signal.

Assay: In Vitro hLTC4 Synthase Enzyme Assay (Test A): In the assay, LTC4 synthase catalyses the reaction where the substrate LTA4 is converted to LTC4. Recombinant human LTC4 synthase is expressed in Piccia pastoralis and the purified enzyme is dissolved in 25 mM tris-buffer pH 7.8 supplemented with 0.1 mM glutathione (GSH) and stored at −80 °C.

The buffer is used as background. Runs are performed in duplicates. The enzymatic reaction is initiated by addition of 0.5 μL LTA4 in diglyme (final assay concentration 8 μM). The reaction is stopped after 1 min by addition of double the reaction volume of a stop solution (MeOH:H2O:acetic acid 70:30:1).

Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation. Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nav 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz.

Current at the end of the 26th pulse to −20 mV was subtracted from the peak current evoked by the 26th pulse to −20 mV to correct for leak current.

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.

Target: Prolyl endopeptidase FAP (SINGLE PROTEIN), Mus musculus
UniProt: P97321
Assay: Enzymatic Assay: Enzyme activities were determined kinetically in a final volume of 200 μl for 10 minutes at 37° C. by measuring the initial velocities of pNA release (405 nm) from the substrate using a Spectramax plus microtiterplate reader (Molecular devices). One unit of enzyme activity was defined as the amount of enzyme that catalyzes the release of 1 μmol pNA from the substrate per minute under assay conditions. The chromogenic substrate Gly-Pro-p-nitroanilide (100 μmol/l) was used at pH 8.3 for DPP IV, Lys-Ala-p-nitroanilide (1 mmol/l) at pH 5.5 for DPP II, Ala-Pro-p-nitroanilide (300 μmol/l) at pH 7.4 for DPP9 and Ala-Pro-p-nitroanilide (2 mmol/l) at pH 7.4 for FAP activity measurement. To evaluate the endopeptidase activity of FAP and the influence of inhibitors thereon, Z-Gly-Pro-AMC and Z-Gly-Pro-p-nitroanilide were used at a final concentration of 300 and 100 μmol/l, respectively. The substrate concentrations were chosen around the Km value obtained under the assay conditions used. Buffer compositions for the DPP assays were reported before in the purification articles−vide supra. The FAP assay buffer consisted of 50 mM Tris pH7.4 containing 100 mmol/l NaCl and 0.1 mg/ml bovine serum albumin. The PREP activity was measured as described by Brandt et al. using the chromogenic substrate Z-Gly-Pro-p-nitroanilide (0.25 mmol/l) at pH 7.5 in the presence of 10 mmol/l DTT. Test compounds were dissolved and diluted in DMSO (final concentration DMSO during assay 5% v/v) except for FAP where dilution of the inhibitor was done in water. Inhibitors are pre-incubated with the enzyme for 15 min at 37° C. before starting the assay by the addition of substrate. The concentration of enzyme and of inhibitor during the preincubation is double of the final concentration during activity measurement.

Assay: Inhibition FRET Assay: The Calbiochem InnoZyme activity kit was used for measuring the inhibition effect inhibitors on human erythrocyte calpain 1 activity. A calpain FRET substrate, (DABCYL)-TPLKSPPPSPR-(EDANS) (SEQ ID NO: 9), was used to detect the activity of Cal1. 20 μM of the FRET substrate, 10 nM of native Cal1, and 20 μM TCEP (reducing agent) were added to the reaction mixture containing assay buffer (Tris [10 mM], NaCl [100 mM], pH 7.4).

Cleavage of the scissile bond amide bond, K-S, releases the fluorophore (EDANS) from the internal quenching molecule (DABCYL), resulting in an increase in fluorescence measured at 320 nm excitation and 480 nm emission wave lengths for 30 min. Each inhibitor was added to the reaction mixture at varying concentrations (10 nM, 100 nM, 1 μM, and 10 μM) to detect inhibition of Cal1 and reduction in fluorescence was measured by 96 well-plate reader.

Assay: Radioligand Binding Assay: The composition of the binding assay buffer is determined in a course of detailed optimization procedure. This resulted in a binding assay buffer constituted by the following components: 25 mM Hepes (pH=7.4), 5 mM MgCl2, 1 mM CaCl2, 100 mM NaCl, supplemented with 0.1% of protease free BSA (as a final concentration). Competition binding assay is performed using 125I-CXCL10 (PerkinElmer, NEX348, specific activity 2200 Ci/mmol) radioligand in a final concentration of 50-70 pM. The nonspecific binding is defined by 150 pM of hr-CXCL10 (R&D Systems, Cat No 266-IP). The total assay volume is equal to 150 ul and contained 1% of DMSO (final concentration). Binding reaction is initiated by adding of membranes (10-20 ug proteins, approximately 5x105 cell equivalents) to the reaction mixture. After 60 minutes of incubation at 25° C. the reaction is terminated by rapid filtration over GF/B glass fibre filters that are pre-soaked with 0.5% polyethyleneimine (Fluka Analytical, P3143) for 1 hour, using a Skatron cell harvester device. Filters then are washed with 8 ml of ice-cold wash buffer (modified binding buffer in which BSA is omitted and the concentration of NaCl is adjusted to 500 mM concentration). The radioactivity retained on the filters is measured by a Wizard 1470 Automatic Gamma counter.

Target: Beta-secretase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: P56817
Assay: Diluted TR-FRET Assay: TR-FRET Assay: The beta -secretase enzyme used in the TR-FRET is prepared as follows:The cDNA for the soluble part of the human beta -Secretase (AA 1-AA 460) was cloned using the ASP2-Fc10-1-IRES-GFP-neoK mammalian expression vector. The gene was fused to the Fc domain of IgG1 (affinity tag) and stably cloned into HEK 293 cells. Purified sBACE-Fc was stored in -80 C. in 50 mM Glycine pH 2.5, adjusted to pH 7.4 with 1 M Tris and had a purity of 40%.The enzyme (truncated form) was diluted to 6 ug/mL (stock 1.3 mg/mL) and the TruPoint BACE1 Substrate to 200 nM (stock 120 uM) in reaction buffer (NaAcetate, chaps, triton x-100, EDTA pH4.5). Enzyme and compound in dimethylsulphoxide (final DMSO concentration 5%) was mixed and pre-incubated for 10 minutes at RT. Substrate was then added and the reaction was incubated for 15 minutes at RT. The reaction was stopped with the addition of 0.35 vol Stop solution (NaAcetate, pH 9).
