IC50 (binding) | = 1 nM | BindingDB_Patents: FLIPR Assay. Compounds were tested for their ability to inhibit C5a-mediated calcium mobilization using a stable cell line over expressing the human C5aR & the Galpha 15 protein on the FLIPR (Fluorescent Imaging Plate Reader) Tetra system. Cells were maintained in culture media containing DMEM (Dulbecco's Modified Eagle Medium) with 4.5 g/L glucose, 10% fetal bovine serum, 100 U/mL, 1x non-essential amino acid, and 250 ug/mL G418 (Geneticin). Prior to testing of compounds, cells were plated at 10,000 cells/well in clear bottom 384-well black plate, and incubated overnight at 37C. with 5% CO2. On the day of experiment, culture media was removed, and replaced with assay buffer HBSS (Hanks' Balanced Salt Solution) with 20 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) and 0.1% BSA (bovine serum albumin) BSA containing calcium 5 dye (Molecular Devices) and 2.5 mM probenecid. After 1 hour incubation at 37C., 5% CO2 for 60 min, cells were pre-incubated with compounds for 30 minutes. | 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.
