Phenotypes

Whole-cell/tissue/organism interactions

We have no records of whole-cell/tissue assays done with this compound What does this mean?

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.

Annotated phenotypes:

We have no manually annotated phenotypes for this drug. What does this mean? / Care to help?
In TDR Targets, information about phenotypes that are caused by drugs, or by genetic manipulation of cells (e.g. gene knockouts or knockdowns) is manually curated from the literature. These descriptions help to describe the potential of the target for drug development. If no information is available for this gene or if the information is incomplete, this may mean that i) the papers containing this information either appeared after the curation effort for this organism was carried out or they were inadvertently missed by curators; or that ii) the curation effort for this organism has not yet started.
 
In any case, if you have information about papers containing relevant validation data for this target, please log in using your TDR Targets username and password and send them to us using the corresponding form in this page (only visible to registered users) or contact us.
