Drug target identification, which includes many distinct algorithms for finding genes and proteins, is the first step in drug discovery. When 3D structures of the targets are available, the problem of target identification is usually converted to finding the best interaction mode between the potential target candidates and probe small molecules. But what happens when the target is unknown or we are looking for off-target effects of our active molecule? (in other words, to which other proteins does our active molecule bind?)
Three servers have been developed for this purpose:
Pharmmapper
http://59.78.96.61/pharmmapper/
PharmMapper Server is a freely accessed web-server designed to identify potential target candidates for the given probe small molecules (drugs, natural products, or other newly discovered compounds with binding targets unidentified) using pharmacophore mapping approach. Benefited from the highly efficient and robust mapping method, PharmMapper bears high throughput ability and can identify the potential target candidates from the database within a few hours.
Reversescreen3D
http://www.modelling.leeds.ac.uk/ReverseScreen3D/about.html
ReverseScreen3D is a reverse virtual screening tool that searches against a biologically-relevant and automatically-updated subset of ligands extracted from the RCSB Protein Data Bank in order to identify potential target proteins that are likely to bind a given compound.
Similarity ensemble approach (SEA)
http://sea.bkslab.org/
The Similarity ensemble approach relates proteins based on the set-wise chemical similarity among their ligands. It can be used to rapidly search large compound databases and to build cross-target similarity maps.
