with Enamine Discovery
We live in a thrilling new era of drug discovery, benefiting from a plethora of well-established and continuously developing scientific modalities, empowered now by artificial intelligence. They enable lightning-fast access to the lead compounds in various therapeutic areas. However, this powerful modern toolkit frequently works on outdated chemical libraries historically available at pharma companies, CROs and screening centers.
Our integrated discovery approach harnesses the world’s leading CRO’s best practices in the integrated drug discovery and capitalizes on:
- Smart selection from Enamine’s latest screening libraries
- Cost control and fast progress in Enamine REAL
- Unique chemistry knowledge accumulated at Enamine
Innovation in drug discovery should be accessible - without losing quality. We offer a fast, cost-efficient start powered by smart libraries, a colossal stock of building blocks, and our REAL technology. This lets us quickly find and prioritize the right compounds, speed up the DMTA cycle, and boost early-phase results.
Whether you come with a validated target, a phenotypic readout, or a disease model, we tailor our approach to fit your specific needs. From early screening to biology and pharmacology, our MedChem experts and project leaders guide each stage with precision, quality, and efficiency.
Our MedChem board brings focus and expertise to every stage. They help set clear priorities, make informed decisions, and keep the project on track—from target evaluation to candidate selection.
Target Evaluation & Validation
We assess biological relevance, druggability, and therapeutic potential to prioritize the right targets.
Target Product Profile (TPP)
We help define key product criteria: mechanism of action, clinical use, and differentiation strategy.
Hit Generation & Screening Strategy
We design efficient screening campaign with the right libraries, technologies, and assays to deliver meaningful hits.
Hit to Lead
We support SAR development, ADME profiling, and synthetic planning to refine hit series into lead candidates.
Lead Optimization
We guide compound design to improve potency, selectivity, and developability—aligned with your TPP.
Candidate Selection
We help integrate efficacy, safety, and PK data to select the best candidates with confidence.
Unique Enamine drug discovery platform
We don't just bring together what already exists at Enamine. We connect the dots and orchestrate all available services and products into a seamless solution.
We are thrilled to announce our collaboration between Enamine and ChemPass, which will open the way for significant advancements in drug discovery. ChemPass will apply its cutting-edge approach to design innovative fragment libraries, and Enamine ensures that these novel compounds are synthesized efficiently. Together, we are establishing a new standard for fragment-screening libraries that will enable scientists to do research more quickly and effectively.

The joint effort between the two companies aims to significantly expand fragment-based hit discovery and to shorten the fragment-to-lead development cycle for challenging biological targets.
ChemPass, applying its Universal Fragment Library Design Platform, will provide general or target-specific fragment libraries based on the customer’s biological target of interest.
Enamine’s team will support the screening of the fragment libraries, the expansion of the obtained fragment hits into lead-like analogues from Enamine REAL® Space, the development of structure-activity relationship (SAR) by a few rapid rounds of screening of REAL® catalog compounds.
Overall, the application of the ChemPass Library Design Platform, Enamine’s REAL® combined with its extensive medicinal chemistry expertise, and Enamine’s screening facilities in discovery biology will deliver optimized hits to our clients in five months, a true acceleration of early-phase drug discovery.

The effectiveness of the hit identification process depends on the screening method and screening library quality. Typically, diversity analysis is utilized to select currently available covalent and noncovalent libraries with desirable properties. To select current covalent and noncovalent fragment libraries with desirable properties, diversity analysis is typically utilised. ChemPass' UFrag platform is based upon pharmacophore, shape and vector analysis of vast ligand binding data in the protein database and it combines several key technologies that are necessary to revolutionise fragment library design.

Conventional fragment libraries created through diversity analyses have been demonstrated to contain a significant number of redundant spacer and pharmacophore motifs, which leads to few to no hits against pockets of challenging targets and high hit rates of redundant rings for specific targets. The outcome is a significant danger of missed chances and a very varied experimental hit rate.
The platform's inherent customisation features allow the library design to target particular protein classes while minimising both the size of the library and the expense of synthetic materials. In order to confirm the notion, a test library was screened against a validated and hard target. The results showed that the test library produced a much higher hit rate and binding site coverage against the hard target than a standard fragment library.
