Cresset solutions are available through easy to use graphical user interfaces, from the command line and through workflow solutions such as Pipeline Pilot™ and KNIME™. Using the Pipeline Pilot interface enables integration of our approach into standard workflows and with other applications. We provide access to all our applications through Pipeline Pilot components that call the corresponding command line application behind the scenes.
Spark enables you to generate highly innovative ideas for your project to explore chemical space and escape IP and toxicity traps.
Given a ‘starter molecule’, you can select a portion to replace. Spark will suggest a list of new molecules containing replacement moieties with similar electrostatic and steric properties ranked using Cresset’s unique molecular field technology, or picking new ligand-protein interactions from the active site using the docking in Spark feature. In addition you can generate your own databases of replacement moieties using the database generator functionality.
In Pipeline Pilot the Spark components provide access to the scaffold hopping and R-group exploring capabilities with a specialized component to enable graphical specification of the portion of the starter molecule to be replaced. A database creation component is also included.
The Spark components are:
- Spark Database Search: Search databases for novel scaffolds or R-groups for a specified molecule
- Spark Database Search (on Client): As above except it enables the graphical selection of the region to be replaced by Spark and the choice of databases to search. This component calls a locally installed copy of Spark
- Generate Spark Database: Generate Spark databases of fragments or reagents
- Spark Database List Viewer: List all available databases for Spark
Blaze is Cresset’s virtual screening platform that is optimized to find novel, diverse hits for your project. Blaze uses Cresset’s unique field technology to generate hits that are similar in electrostatics and shape space to the query molecule, but with diverse 2D structures. It runs on a Linux or GPU cluster and is designed to manage compounds, collections, conformations, job distribution and searches.
The Blaze components are:
- New Blaze Search: Start a Blaze search
- Blaze Searches Viewer: Report the list and status of all Blaze searches
- Detailed Blaze Search Viewer: Report detailed information on a specific Blaze search
- Download Blaze Search Results: Retrieves the results from a Blaze search
- Blaze Collections Viewer: Shows the Blaze collections which are available for searching.
- Upload Molecules to Blaze Collection: Update collections in Blaze
- Blaze Status Viewer: Report the status of the Blaze server and any running jobs
Note: Forge is Cresset's legacy ligand-based workbench providing an informative approach to molecule design and structure activity relationship (SAR) analysis.
In Pipeline Pilot the Forge components enable ligand comparisons and investigation, building of qualitative and quantitative 3D models of activity, scoring of new molecule designs, creation of molecular similarity and disparity matrices and building of detailed pharmacophores.
The Forge components are:
- Forge Align: Align and score molecules to a 3D reference molecule using electrostatics and shape or common substructure; molecules are conformationally hunted if necessary
- FieldTemplater™: Compare molecules using their electrostatics, shape and hydrophobic fields in order to find common pharmacophores
- Activity Miner™: Generate similarity, distance or disparity matrix from a set of aligned molecules using 2D and 3D measures of similarity
- Forge Build: Generate regression and classification models for activity using Forge 3D-QSAR or Machine Learning methods (k-Nearest Neighbor, Random Forest, Relevance Vector Machines and Support Vector Machines)
- Forge Score: Predict activities for new molecules using a model generated with Forge Build
- Forge Model Viewer (on Client): Launch Forge to view Forge models generated with Forge Build
- Forge Surface Writer: Generate the electrostatic, shape and hydrophobic field surfaces for the input molecules
Flare is an integrated platform for ligand-based and structure-based drug design that enables research chemists to discover novel small molecules more efficiently and effectively.
In Pipeline Pilot the Flare components enable full access to the Flare functionality through the Flare Python API.
The Flare components are:
- pyflare: Runs a Python script which has access the Flare Python API
The XedTools components give access to core technologies such as ligand minimization and conformation generation. They are:
- XedMin™: Ligand minimizer (using Cresset’s proprietary XED force field) to optimize ligands in isolation or in a specified context such as the protein active site
- XedeX™: Create low energy, diverse conformation populations for a ligand
Cresset supplies two generic viewer components which call the main graphical user interfaces on the client machine. They are:
- Forge Molecule Viewer (on Client): Useful for visualizing the electrostatic fields around the input molecule or for viewing the results of other Cresset components
- Flare Ligand and Protein Viewer (on Client): Launches Flare to view ligand and protein structures
The Cresset Pipeline Pilot components wrap functionality of key binaries and hence both the application binaries and the Cresset Pipeline Pilot Package must be installed. Download the zipped version of the Cresset Pipeline Pilot Package, then read the installation instructions.
The software used by the Cresset Pipeline Pilot components requires a valid license file which will be supplied by Cresset. If you are a customer and cannot locate your license file, then please contact us. Alternatively, request an evaluation license.
Cresset provides example workflows that encompass each of the Cresset Pipeline Pilot components. The examples are included in the installation package and can be found under Protocols > Examples > Chemistry > Cresset. Additional examples for Blaze that require configuration before they will execute (which prevents inclusion in the installation package) are available for download here.
