Ki (binding) | = 3.7 nM | BindingDB_Patents: FLIPR Assay. The agonistic or antagonistic effect of the substances to be tested on the vanilloid receptor 1 (VR1) can also be determined using the following assay. In this assay, the influx of Ca2+ through the channel is quantified with the aid of a Ca2+-sensitive dye (type Fluo-4, Molecular Probes Europe BV, Leiden, the Netherlands) in a fluorescent imaging plate reader (FLIPR, Molecular Devices, Sunnyvale, USA).Method:Chinese hamster ovary cells (CHO K1 cells, European Collection of Cell Cultures (ECACC) United Kingdom) are stably transfected with the VR1 gene. For functional testing, these cells are plated out on poly-D-lysine-coated black 96-well plates having a clear base (BD Biosciences, Heidelberg, Germany) at a density of 25,000 cells/well. The cells are incubated overnight at 37 C. and 5% CO2 in a culture medium (Ham's F12 nutrient mixture, 10% by volume of FCS (foetal calf serum), 18 ug/ml of L-proline). The next day the cells are incubated with Fluo-4. | ChEMBL. | No reference |

Ki (binding) | = 7.2 nM | BindingDB_Patents: FLIPR Assay. The agonistic or antagonistic effect of the substances to be tested on the rat-species vanilloid receptor 1 (VR1/TRPV1) can be determined using the following assay. In this assay, the influx of Ca2+ through the receptor channel is quantified with the aid of a Ca2+-sensitive dye (type Fluo-4, Molecular Probes Europe BV, Leiden, the Netherlands) in a fluorescent imaging plate reader (FLIPR, Molecular Devices, Sunnyvale, USA).Method:Complete medium: 50 ml HAMS F12 nutrient mixture (Gibco Invitrogen GmbH, Karlsruhe, Germany) with10% by volume of FCS (foetal calf serum, Gibco Invitrogen GmbH, Karlsruhe, Germany, heat-inactivated);2 mM L-glutamine (Sigma, Munich, Germany);1% by weight of AA solution (antibiotic/antimyotic solution, PAA, Pasching, Austria) and 25 ng/ml NGF medium (2.5 S, Gibco Invitrogen GmbH, Karlsruhe, Germany). | 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.
