colony stimulating factor 1 receptor/Macrophage colony stimulating factor receptor in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL1844] [GtoPdb: 1806] [UniProtKB: P07333]
ChEMBL	Inhibition Assay: Reagents and consumables were purchased from Sigma Aldrich, Carna Biosciences, or Caliper Life Sciences. All assay reaction conditions for IC50 determinations were within the linear range with respect to time and enzyme concentration. In a 384 well polypropylene plate, c-FMS (0.14 nM, Carna 08-155) was pre-incubated in a 100 mM Hepes-NaOH pH 7.5 buffer containing 0.01% Triton X-100, 10 mM MgCl2, 0.1% BSA, 1 mM DTT, 10 uM sodium orthovanadate and 10 uM beta-glycerophosphate and compound with a concentration of 2.5% DMSO for 15 minutes at room temperature. The reaction was initiated with an equal volume of peptide substrate (Caliper Life Sciences catalog no. 760430) and ATP in the aforementioned buffer. The final concentrations in the reaction were 70 pM c-FMS, 1.5 uM peptide substrate and 500 uM ATP (ATP Km). The reaction was incubated at room temperature for 120 minutes and terminated with a buffer containing excess EDTA (100 mM Hepes-NaOH pH 7.5, 0.02% Brij, 0.1% CR-3.

ChEMBL	Inhibition Assay: Reagents and consumables were purchased from Sigma Aldrich, Carna Biosciences, or Caliper Life Sciences. All assay reaction conditions for IC50 determinations were within the linear range with respect to time and enzyme concentration. In a 384 well polypropylene plate, TrkA (0.4 nM, Carna 08-186) was pre-incubated in a 100 mM Hepes-NaOH pH 7.5 buffer containing 0.01% Triton X-100, 10 mM MgCl2, 0.1% BSA, 1 mM DTT, 10 uM sodium orthovanadate and 10 uM beta-glycerophosphate and compound with a concentration of 2.5% DMSO for 15 minutes at room temperature. The reaction was initiated with an equal volume of peptide substrate (Caliper Life Sciences catalog no. 760430) and ATP in the aforementioned buffer. The final concentrations in the reaction were 200 pM TrkA, 1.5 uM peptide substrate and 55 uM ATP (ATP Km).

ChEMBL	Inhibition Assay: Reagents and consumables were purchased from Sigma Aldrich, Carna Biosciences, or Caliper Life Sciences. All assay reaction conditions for IC50 determinations were within the linear range with respect to time and enzyme concentration. In a 384 well polypropylene plate, TrkB (0.6 nM, Carna 08-187) was pre-incubated in a 100 mM Hepes-NaOH pH 7.5 buffer containing 0.01% Triton X-100, 10 mM MgCl2, 0.1% BSA, 1 mM DTT, 10 uM sodium orthovanadate and 10 μM beta-glycerophosphate and compound with a concentration of 2.5% DMSO for 15 minutes at room temperature. The reaction was initiated with an equal volume of peptide substrate (Caliper Life Sciences catalog no. 760430) and ATP in the aforementioned buffer. The final concentrations in the reaction were 300 pM TrkB, 1.5 μM peptide substrate and 70 μM ATP (ATP Km).

ChEMBL	Inhibition Assay: Human TrkC, catalytic domain [456-825(end) amino acids of accession number NP-002521.2] was expressed as N-terminal GST-fusion protein (69 kDa) using baculovirus expression system. GST-TRKC was purified by using glutathione sepharose chromatography and stored in 50 mM Tris-HCl, 150 mM NaCl, 0.05% Brij35, 1 mM DTT, 10% glycerol, pH7.5 at -80 C. The kinase activity was measured by off-chip mobility shift assay. The enzyme was incubated with fluorecence-labeled substrate, Srctide, in the presence of 100 uM of ATP (Mg/or Mn)/ATP). The phosphorylated and unphosphorylated substrates were separated and detected by LabChip 3000.	B	9.3	pIC50	0.5	nM	IC50	US-9067914-B1. Tropomyosin-related kinase (TRK) inhibitors (2015)
