Library Design
Chemspace's Delivering Discovery Solutions™ offers library design to help researchers identify new hits and improve hit rates in HTS campaigns.
We propose flexible collaboration business models tailored to meet all your needs and budget.
Delivering Discovery Solutions™ in library design has three main approaches:
Cheminformatics approach
We use key molecular and structural features, such as molecular weight, hydrogen bond donors/acceptors, etc., to design diversity-oriented libraries, drug-like libraries, lead-like libraries, fragment libraries, - among many others.
Target-based approach
With 3D structural information about a particular biological target or family of targets, we can use molecular docking to predict the binding affinity of the putative ligands. This makes the above virtual screening approach one of the most powerful techniques to “cherry-pick” the most promising compounds out of a billion-sized Chemspace catalog.
Ligand-based approach
When 3D structures of a particular biological target are unavailable, we can design a focused library based on the known binders
Library Synthesis
Chemspace's Delivering Discovery Solutions™ provides library synthesis through our valuable chemistry partners to support drug discovery projects. We offer flexible collaboration business models to meet your requirements and fit your budget expectations.
Common library synthesis models:
Make-on-demand analogs
Compounds for a library will be selected from Freedom Space, Enamine Database, REAL, xREAL or custom spaces.
Scaffold-based library
A scaffold provided by either Chemspace or a customer is decorated with a diverse set of building blocks.

Chemspace KNIME Node
KNIME Analytics Platform is a powerful open source tool for data mining. We have created the Chemspace node for KNIME that allow to search directly in Chemspace database (11.5 billion compounds) without using your browser.
The node allows for search in all database sections at the same time or in any of them separately.You can embed Chemspace node into your custom in-house workflow, get the information on marketed compounds and post-process the search results in any desired way.
To use the node, you will need the Chemspace API Key that we will send via email. Contact us at [email protected] to request the Key.
You can get up to 2000 results per each query performing up to 40 requests per minute.
What should be the input?
The node accepts SMILES cells (or String cells with SMILES) for Structure Search and String/numeric cells for ID Search.
What is the output?
For each query where results are found, the nodes generate output with SMILES, Chemspace IDs, and URLs.
Also there is an option to show pre-calculated PhysChem parameters for hits.How to use the node?
Access to Chemspace database from KNIME interface is provided for free, but the API Key is needed. Please follow the instructions below to get the Key:
- Register on Chemspace website
- Email us on [email protected] with Key request and provide us with your username or email used for registration
- Get the Key and explore the chemical universe!
Please see our presentation on Chemspace Search node to explore the features of it!
How to install Chemspace Search nodes?
- Launch KNIME.
- Open Help menu and click Install New Software.
- Type https://chem-space.com/knime/ into the Work with field.
- Tick the Chemspace KNIME nodes checkbox.
- Click next and follow the further instructions.
- For changes to take effect, you will need to restart KNIME. When the installation is complete, the application will propose you to restart it.
- You can find Chemspace nodes in your Node Repository after the restart
Building Blocks for Library Synthesis
Synthesis of a compound library is an important step prior to wet screening, but it can also become a very costly process. Of course, you can purchase compounds from our Screening Compounds Collection, but what if you want something more specific?
Ordering building blocks in gram quantities for such purposes can be very expensive, but we've got your back!
Chemspace offers a very useful service – Building Blocks for Library Synthesis.
- It is a collection of 200K+ compounds from 5 different suppliers, that you can choose from.
- Compounds are supplied in umol quantities
- The order will be delivered to you in 1-2 weeks.
- Customized formatting of your choice (vials, plates, etc.)
- Consolidated shipments for your best experience
This approach works great for conducting reactions because compounds are shipped pre-weighted in vials. This means that you'll only have to add other components and enjoy the result. A great time saver too!
Interested? Contact us at [email protected] for more information.
3D Chemical Spaces
Two of our most popular Screening Compounds Chemical Spaces are available through Molsoft (https://molsoft.com/addons/conf/) as sets of generated 3D structures.
These sets are meant to save your time by providing you with already generated 3D structures for computational purposes. We are trying to do our best to be present on different platforms and provide the most easy-to-use products.
If you wish to download the files or have any questions about 3D Chemical Spaces, please drop us a line at [email protected].

DNA-Encoded Libraries with ML-Supervised Data Processing
Chemspace offers a service that combines DNA-encoded libraries (DEL), Machine learning (ML), and large chemical spaces (CS) to speed up the early Drug Discovery process and reduce its cost while maintaining a high hit rate.
This idea was first introduced by Kevin McCloskey et al., who built ML models on the information created by a DEL screen and successfully applied them to commercial spaces. As a result, they received a high percentage of active compounds, which were readily available for wet screening.
Here at Chemspace, we provide a full service by conducting a DEL screen on your target with our partners, building a machine-learning model, and providing you with the potentially active compounds for screening. This approach is perfect for projects where you have access to purified protein but lack crystal structure or any knowledge about its activity.
Advantages over traditional DEL screening
- Saving time and effort. The off-DNA synthesis step remains the time and resource-limiting factor.
- Cost-effectiveness. Compounds for testing are selected from commercially available spaces, their price is significantly lower compared to custom synthesis.
For this approach Chemspace can offer
- Access to DEL collections up to 4B compounds, covalent and custom DELs
- DEL screening services
- ML services
- Hit generation from Enamine REAL –39B molecules
- Wet screening and hit confirmation
- Hit expansion and follow-up.
Classical Approach
DNA-encoded libraries (DELs) are a powerful and innovative approach to Drug Discovery that has gained significant attention in recent years. DELs involve the synthesis of large collections of diverse small molecules, where each molecule is linked to a DNA tag that encodes its chemical identity. By screening these libraries against a target of interest, researchers can identify lead compounds that bind to the target with high affinity and selectivity.
Advantages over traditional Drug Discovery
- The ability to rapidly screen large numbers of compounds in a single experiment
- Reduced cost of screening
- A high degree of chemical diversity.
For this approach Chemspace can offer
- Access to DEL collections, up to 4B compounds, including covalent and custom DELs
- Conducting the DEL screen on your target
- Data analysis and hit proposal based on screening results
- Off-DNA synthesis of the hit compounds for hit confirmation
- Wet screening of potential hits
- SAR, analogs synthesis for compound optimization.
