IC50 (binding) | = 87.3 nM | BindingDB_Patents: Fluorescence Resonance Energy Transfer 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 assay is terminated with by addition of Tris buffer, which raises the pH to neutrality, and the fluorescence is determined. 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). | ChEMBL. | No reference |

IC50 (binding) | = 374140 nM | BindingDB_Patents: Fluorescence Resonance Energy Transfer Assay. Recombinant Cat D was expressed in CHO cells. The assay buffer for CathepsinD is 0.05 M citrate pH 3.5, 10% DMSO final, 5 mM CHAPS. The Cat D enzyme (9 nM) is pre-incubated for one hour with inhibitors, typically in about 1 uL of DMSO according to a serial dilution, is added thereto. The assays are effectively started by the addition of different FRET substrates (20 nM for Cat D) and the combination is incubated for one hour. The FRET assay is terminated with by addition of Tris buffer, which raises the pH to neutrality, and the fluorescence is determined. The FRET substrate is a peptide with commercially available fluorophore and quencher, on opposite sides of the BACE cleavage site. The Cat D substrate peptide sequence is based on sequence #1 of Table 1 from Gulnik et al. FEBS Letters v413 p379-384 1997. Proteolytic cleavage of the FRET substrate releases quenching of fluorescence (Cat D excitation 500 nm and emission 580 nm). | ChEMBL. | No reference |

Many chemical entities in TDR Targets come from high-throughput screenings with whole cells or tissue samples, and not all assayed compounds have been tested against a single a single target protein, probably because they get ruled out during screening process. Even if these compounds may have not been of interest in the original screening, they may come as interesting leads for other screening assays. Furthermore, we may be able to propose drug-target associations using chemical similarities and network patterns.
