Spark™
Generate highly innovative ideas for your project to explore chemical space and escape IP and toxicity traps
Request an evaluationSpark
Find biologically equivalent replacements for key moieties in your molecule and be guided through the process of growing and linking ligands.
Whether your research goal is R-group exploration, patent busting or scaffold hopping, your results will include structures you have thought of yourself, plus new structures that make chemical sense and are totally unexpected.
Spark gives you a head start, letting you explore the likely results of your substitutions from the desktop before transferring your best ideas to the bench.
- Generate highly innovative ideas for your project
- Move to new series and non-obvious IP by swapping scaffolds
- Find the best R-groups from your reagents
-
Grow a ligand into new space, picking ligand-protein interactions directly from the active site, or guided by existing ligands
- Join two ligands sitting in different regions of your protein active site
- Cyclize a molecule by joining two atoms with a linker
- Search for an R-group which will displace a crystallographic water molecule near your ligand
Spark databases
Spark databases are derived from commercially available screening compounds (eMolecules screening compounds), literature reports (ChEMBL), theoretical ring systems (VEHICLe) and commercial reagents (eMolecules building blocks).
Larger databases are split based on the frequency of occurrence of the fragments.
Spark databases based on small molecule crystal structure data from the Crystallography Open Database and Cambridge Structural Database are also available.
Easy to use interface
- Quickly generate a range of novel molecules from an initial structure
- Profiling and scoring help you choose the most innovative and tractable leads with the properties you need
- Use filters to find the result with the right mix of physicochemical properties and biological activity
- Visualize results in detail side-by-side, or cluster similar chemical scaffolds
- Search for moieties from real, published or unexplored compound databases
- Create your own custom databases based on the reagents you have available or your proprietary chemistry
Spark
Customers say Spark is the best scaffold hopping software they have ever used
Spark works in electrostatic and shape space so it can match the nature of your molecules better than any other tool. When you grow ligands into new space, or link ligands from different regions of your protein active site, Spark gives you complete control. You can choose to be guided by your knowledge of existing ligands, your reagent availability, or by the ideal property profile.
Testimonials from Spark users
One of the compounds discovered with Spark is now our key lead against this target and further analogue synthesis is underway. Spark has certainly helped direct us towards some novel and very useful SAR on this occasion.
Laurent Rigoreau, Group Leader Medicinal Chemistry, Cancer Research Technology Discovery Laboratories
Great to see how this scaffold-hopping software has developed over the years and is being refined to take account of the real life problems facing medicinal chemists, in balancing synthetic accessibility and potency with the physicochemical properties required to produce drugs.
Barret Kalindjian, SBK Pharma Consultancy Services Ltd
A very valuable asset for the drug discovery toolbox.
Barret Kalindjian, SBK Pharma Consultancy Services Ltd
Forge and Spark are excellent programs for LBDD.
Dr. Prija Ponnan, Department of Chemistry, University of Delhi
Students who use Cresset tools tend to gain an affinity with a number of med-chem concepts far earlier than those who do strictly organic projects, for example using Spark to identify new frameworks that possess favorable properties and which can then be synthesized in the lab via a novel reaction.
