SwissBioisostere is a database containing information on millions of molecular replacements and their performance in biochemical assays. It is meant to provide researchers in drug discovery projects with ideas for bioisosteric modifications of their current lead molecule, and to give access to the details on particular molecular replacements.
SwissSimilarity allows the rapid screening of small to very large-scale libraries of drugs, bioactive small molecules, commercially available compounds, and an ultra-large library of virtual compounds readily synthesizable from commercially available reagents. The virtual screening can be performed using molecular fingerprints, as well as superpositional or fast non-superpositional 3D shape similarity approaches.
SwissTargetPrediction is an online tool to predict the targets of bioactive small molecules in human and other vertebrates. This is useful to understand the molecular mechanisms underlying a given phenotype or bioactivity, to rationalize possible side-effects or to predict off-targets of known molecules.
