Screening

Software

  • MedChem Studio. Cheminformatics platform for computational and medicinal chemists supporting lead identification and optimization, in silico ligand based design, and clustering/classifying of compound libraries. It is integrated with MedChem Designer and ADMET Predictor. Distributed by Simulation Plus, Inc.

Ligand design

Software

  • BREED. Program for ligand-based ligand design, by hybridization of known ligands. Distributed by Schrodinger.
  • TOPAS (now DOGS). Program for ligand-based fragment-based ab initio ligand design, using molecular similarity towards a template compound. Developed by the Swiss Federal Institute of Technology Zurich (ETHZ).
  • LeadGrow. Provides features for focused combinatorial library generation and screening to grow a lead molecule and perform lead optimization. Provides Lipinski screen and activity prediction using pre-generated QSAR models. Provided by VLife.
  • Muse. A molecular invention workflow designed to accelerate the identification and optimization of lead candidates. Uses a ligand-based scoring to generate ideas that optimize the shape and pharmacophoric similarity to a set of lead structures. Formerly EAInventor. Distributed by Tripos.
  • Phase. Program for ligand-based drug design using pharmacophore modeling. Distributed by Schrodinger.
  • MOE. Suite of medicinal chemistry tools like Ligand-Receptor Docking, Protein/Ligand Interaction Diagrams, Contact Statistics, Electrostatic, & Interaction Maps, LigX (Ligand Optimization in Pocket), Ligand & Structure-Based Scaffold Replacement, Multiple Molecule Flexible Alignment, Conformation Generation, Analysis, & Clustering, Active Site Detection & Visualization, Multi-Fragment Search, Ligand & Structure-Based Query Editor, High-Throughput Conformation Generation, Pharmacophore Search. Distributed by Chemical Computing Group.
  • INDDEx. (Investigational Novel Drug Discovery by Example) logic-based machine-learning technique to learn from a training dataset of active and inactive molecules from a screening programme to generate quantitative logic-based rules. These rules are in the form of pairwise distances between fragments of substructure, which provide vital chemical insight into the stereochemical and structural requirements for biological activity. Provided by Equinox Pharma. Reduced rates are available for academic groups.
  • ReCore. Replaces a given pre-defined central unit of a molecule (the core), by searching fragments in a 3D database for the best possible replacement, while keeping the rest of the query compound. Additionally, user-defined "pharmacophore" constraints can be employed to restrict solutions. Distributed by BioSolveIT.
  • LigMerge. Program combining structures of known binders to generate similar but structurally distinct compounds that can be tested for binding. Free and open source. Distributed by the National Biomedical Computation Resource.
  • MedChem Studio. Cheminformatics platform for computational and medicinal chemists supporting lead identification and optimization, in silico ligand based design, and clustering/classifying of compound libraries. It is integrated with MedChem Designer and ADMET Predictor. Distributed by Simulation Plus, Inc.
  • LoFT. Tool for focused combinatorial library design using a (ligand-based) weighted multiobjective scoring function based on physicochemical descriptors.
  • ACD/Structure Design Suite. Helps chemists optimize the physicochemical properties of their compounds. The software suggests alternative substituents (at a site/sites on the molecule) to drive the property of choice in the desired direction. Helps adjust aqueous solubility, lipophilicity (logP or logD), or change the ionization profile (pKa) of molecules. Distributed by ACD/Labs.
  • CoG. Program for ligand-based ab initio ligand design, using a graph-based genetic algorithm.
  • Flux. Program for ligand-based ligand design using a EA approach.
  • ilib diverse. Program for creating virtual libraries of drug-like organic molecules suitable for rational lead structure discovery. Ligands are designed by combining user-defined fragments according to state-of-the-art chemical knowledge. Generated compounds can be filtered according to a variety of physico-chemical filters. Developed by inte:ligand.
  • CAESA. Computer Assisted Estimation of Synthetic Accessibility is a computer program to automatically rank sets of molecules according to their ease of synthesis. Distributed by SimBioSys.
  • EMIL. (Example Mediated Innovation for Lead evolution). Suggests chemical modifications to hits to turn them into bona fide leads. EMIL searches through its Knowledge Base looking for similar chemistry and how it was optimized for potency and bioavailability (Iientification of bioisosteric/bioanalogous structures, indication of empirical information of the modification, such as change in physicochemical, in vitro and in vivo effects, etc...). Distributed by CompuDrug.
  • Legio. Indigo-based GUI application that exposes the combinatorial chemistry capabilities of Indigo. Free and open source. Distributed by GGA software.

Databases

  • SwissBioisostere. Freely available 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. Users can provide a molecular fragment and get possible replacements, along with the biological assays in which they were observed. Users can also provide a given molecular replacement and get the corresponding information. The data were created through detection of matched molecular pairs and mining bioactivity data in the ChEMBL database. Developed and maintained by Merck Serono and the Swiss Institute of BioInformatics.
  • VAMMPIRE. (Virtually Aligned Matched Molecular Pairs Including Receptor Environment) matched molecular pairs database for structure-based drug design and optimisation. By building MMPs between PDBbind and ChEMBLdb ligands VAMMPIRE extrapolates the two-dimensional ChEMBLdb ligands to the assumed, three-dimensional binding mode and introduce the received binding information into the database. Provided by the Institute of Pharmaceutical Chemistry / Goethe University Frankfurt, Germany.
  • sc-PDB-Frag. Database of protein-bound fragments to help selecting truely bioisosteric scaffolds. The database allows to (i) search fragment among PDB ligands or sketch it; (ii) define similarity rules to retrieve potential bioisosteres; (iii) score bioisosteres according to interaction pattern similarity; (iv) align bioisosteres to the reference scaffold; (v) Visualize the proposed alignment.

ADME Toxicity

Software

  • MedChem Studio. Cheminformatics platform for computational and medicinal chemists supporting lead identification and optimization, in silico ligand based design, and clustering/classifying of compound libraries. It is integrated with MedChem Designer and ADMET Predictor. Distributed by Simulation Plus, Inc.
