Collection of databases with standalone databases, which gives opportunity for customers to integrate the data into their internal tools and databases, as well as online databases, that are available to the customers from a dedicated website where an individual can query and export the data in the selected format. The standalone database topics include medicinal chemistry, drugs and target class based compounds. The online databases are comprised of three major compilations: GVK BIO Online Structure Activity Relation Database (GOSTAR), GVK BIO Biomarker Database (GOBIOM), and Clinical Trial Outcome Database (CTOD).
Software program that simulates molecular interactions. It has features that allow broad application to many-particle systems with a comprehensive set of energy functions, a variety of enhanced sampling methods, and support for multi-scale techniques, and a range of implicit solvent models. It also primarily targets biological systems including peptides, proteins, prosthetic groups, small molecule ligands, nucleic acids, lipids, and carbohydrates, as they occur in solution, crystals, and membrane environments. CHARMM can also be applied to inorganic materials with applications in materials design and has a comprehensive set of analysis and model builiding tools.
Database of marketed and developed drugs indexed with internationally-recognized drug names, synonyms, trade names, trivial names and trial preparation codes in one source, plus compound structures and activity data. Each record has chemical structure and is classified by drug activity, mechanism of action, treatment, manufacturer, synonyms, medical nformation and literature references.
Database of commercially accessible screening compounds from international chemistry suppliers. iResearchLibrary is updated on a weeky basis and offers support for creating internal screening libraries containing commercially accessible compounds, developing exploratory and targeted libraries, selecting commercially accessible compounds for SAR, lead expansion, and hit follow-up projects, and using structures for pharmacophore searching, virtual screening and other computational work.
Software that takes a macromolecular structure containing a bound ligand and identifies the key features on the ligand which are interacting with points on a protein. Its features include: automatic interpretation of PDB ligands using geometry, dictionaries and rule; advanced handling of co-factors, ions, water molecules and covalently bound ligands; pharmacophore export to Catalyst(tm), MOE(tm) and PHASE(tm) for virtual screening; and the ability to treat co-factors and water molecules as part of the ligand or part of the macromolecule.
Web-based system for searching and analysing protein-ligand structures in the Protein Data Bank (PDB). The database provides an easily accessible web-browser interface and clear 3D structure visualisation that allows for 3D protein-ligand interaction searches, automatic superimposition and detailed analysis of related binding sites to identify protein flexibility, ligand overlap, and conserved water positions.
Software package that uses homology modeling and fold recognition to make protein structure predictions.
Public web server that provides structures, data, tools, programs and other useful information to the public for computer-aided drug design. It is the official database of the Computer-Aided Drug Design (CADD) Group.
Complementary OEDocking tool for virtual screening, it performs a systematic and non-stochastic examination of all possible protein-ligand poses. The software also filters for shape complementarity and chemical feature alignment before selecting and optimizing protein-ligand poses.
Pharmacophore modeling software to create 3D structure activity relationships, screen databases, and generate hits through establishing a chemical space occupied by active ligands. Used in drug design.
