IC50 (binding) | = 170 nM | BindingDB_Patents: Immunofluorescence Resonance Energy Transfer (FRET) Assay. The FRET assay was performed essentially as described in Gruninger-Leitch et al., Journal of Biological Chemistry (2002) 277(7) 4687-93 (Substrate and inhibitor profile of BACE (beta-secretase) and comparison with other mammalian aspartic proteases). In summary, a peptide is designed that is cleaved by the protease. The peptide is labelled with dabcyl at the N terminus and Lucifer Yellow at the C-terminus, such that for an intact peptide the Lucifer Yellow fluorescence is quenched by the dabcyl. When the peptide is cut by BACE2, the quenching is removed and a fluorescent signal is generated. The assay was performed as described in Grueninger et al. 2002 at pH 4.5 using a substrate concentration of 5 uM. A FRET peptide based on the TMEM27 sequence was devised. dabcyl-QTLEFLKIPS-LucY (SEQ ID NO: 1). BACE2 had a high activity against this sequence, which is unrelated to the known APP-based substrates. Conversely, BACE1 had insignificant activity against this peptide. | 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.
