Automatic Reduction of Ion Spectra to Ontology (ARISTO) is a web tool which provides information regarding the chemical nature/ontology of the compound underlying an input electron ionization mass spectrum.
ChemMine Tools is an online service for analyzing and clustering small molecules. A suite of cheminformatics and data mining tools for data visualization, structure comparison, similarity searching, compound clustering and prediction of chemical properties are available.
EDULISS (EDinburgh University Ligand Selection System) database stores structural, physicochemical and pharmacophoric properties of small molecules. For each compound a single 3D conformer is stored along with over 1600 calculated descriptor values (molecular properties). A very efficient method for unique compound recognition is demonstrated by making use of small subgroups of the descriptors.
The wwLigCSRre web server performs ligand-based screening using 3D molecular similarity engine. Inputted 3D ligand molecules may be screened against banks such as Kinase-, CNS-, GPCR-, ion-channel-, antibacterial-, anticancer-, and analgesic-focused libraries or DrugBank database.
