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.
ChemSynthesis is a freely accessible database of chemicals. This website contains substances with their synthesis references and physical properties such as melting point, boiling point and density. Over 40,000 compounds are listed.
Frog2 (Free Online Drug Conformation 2) is a service aimed at generating 3D conformations for small molecules starting from their 1D, 2D or 3D descriptions (smiles, sdf or mol2 input formats). Frog2 improves upon Frog1 by embedding new energy minimization and ring generation capacities.
A web-based tool for estimating Ki values from experimentally determined IC50 values for inhibitors of enzymes and of binding reactions between macromolecules and ligands.
MetalDetector identifies CYS and HIS involved in transition metal protein binding sites beginning with protein sequence alone. The geometry of the metal binding site is also predicted.
pepMMsMIMIC is a peptidomimetic compound virtual screening tool based on a multi-confromers 3D-similarity search strategy. Using as input the 3D structure of a peptide bound to a protein, pepMMsMIMIC suggests which chemical structures are able to mimic the protein-protein recognitiuon of this natural peptide using pharmacophore and shape similarity techniques.
PharmMapper is a web server that identifies potential drug targets from its PharmTargetDB for a given input molecule. Potential targets are identified from a prediction of the spatial arrangement of features essential for a given molecule to interact with a target.
PubChem BioAssay Service expands upon PubChem. It is a set of web servers which provide for rapid data retrieval, integration, and comparison of biological screening results, exploratory structure-activity analysis and target selectivity examination.
SePreSA is a server for the prediction of populations susceptible to serious adverse drug reactions. A drug molecule is submitted to the server and its potential interaction with multiple adverse drug reaction targets is calculated using DOCK program.
SIMilar COMPound (SIMCOMP) computes chemical similarity searches and SUBstructure matching of COMPounds (SUBCOMP) computes chemical substructure searches. Outputs are linked to the KEGG pathway and BRITE databases for interpretation of biological meanings of chemical structures.
The SuperPred web server compares the structural fingerprint of an input molecule to a database of drugs connected to their drug targets and affected pathways. As the biological effect is well predictable, if the structural similarity is sufficient, the web-server allows prognoses about the medical indication area of novel compounds and to find new leads for known targets. Such information can be useful in drug classification and target prediction.
The University of Minnesota Pathway Prediction System (UM-PPS) is a web tool that recognizes functional groups in organic compounds that are potential targets of microbial catabolic reactions and predicts transformations of these groups based on biotransformation rules. Multi-level predictions are made.
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.
