Enamine to be the exclusive supplier of Astex’ MiniFrag Library

Enamine Ltd. and Astex Pharmaceuticals (UK) have cooperated to provide wide access to Astex’ MiniFrag library, an efficient Fragment-based Drug Discovery tool for identification of hot and warm spots of protein targets. The Library is readily available from Enamine in any suitable format, including dry samples or assay-ready high concentration (1M, 100mM) aqueous soaks in containers of preferred type. The detected MiniFrag hits can be followed-up with a wide range of stock available and synthetically feasible derivatives as well as with building blocks for introduction of the relevant structural features for lead optimization.

New RNA targeted library has been created!

The number of targets, the number of diseases that one could go after by targeting RNA, is almost unimaginable, says Matt Disney, a chemist at the Scripps Research Institute.

In response to growing interest and recent advancements in targeting RNA our experts designed dedicated library of small molecules predicted to bind to RNA targets. In contrast to the classical protein targets and disease treatment, drugging RNA reveals absolutely new way to treat and prevent different disorders.

Our freshly-made library is ready for fast shipment within a week in various custom formats.

RNA Library contains 8 960 compounds. Read more >>

    Let’s fight COVID-19 together

    An international group of scientists from academia and industry, including Enamine, is trying to help combat COVID-19. This effort began when Chinese scientists worked rapidly to determine the structure of the novel SARS‑CoV‑2 main protease (Mpro), which triggered a massive crystal-based fragment screen at the XChem facility at UK’s Diamond Light Source. For more details, please visit https://www.diamond.ac.uk/covid-19. With the same urgency, the scientists are now trying to progress these data towards what is desperately needed: effective, easy-to-make anti-COVID drugs https://covid.postera.ai/covid.

Express Lead Library

Readily accessible lead-like libraries based on Enamine's latest core building blocks with unique underrepresented structures

5.82 M compounds

Express Lead Library (ELL) is an extension of REAL database focusing on novel screening compounds that can be synthesized from the most recently synthesized building blocks. Having the largest building block inventory Enamine continues its expansion. Each month it is enriched with 2,000 new functionalized compounds synthesized in-house. Many of them feature results of our latest research in medchem-driven organic synthesis. Following our doctrine of accelerating drug discovery it’s important to make such chemotypes available for biological screening as soon as possible. We have selected only unusual building blocks that contain at least 2 rings or 7-membered rings. They are called “core building blocks” as they bear essential molecular complexity rendering novelty to the enumerated compound libraries. All terms of REAL database including synthesis time of 3 weeks with at least 85% success rate are also valid for supplies from ELL. It is recommended as an abundant source of selected novel compounds in Compound Collection Enhancement programs and virtual screening projects.

  • 1 592 New building blocks synthesized in 2015-2017
  • Exclusivity. Over 90 % are offered on the market only by Enamine
  • Unique underrepresented structures. The selected building blocks have no close analogues in stock and have not been largely used for library synthesis: > 92 % have less than 25 derivatives in our stock screening collection
  • Essential molecular complexity. Fragment complexity > 600

ELL molecules

  • 5.82 Million new compounds
  • Lead-like physicochemical profiles: MW < 350, sLogP < 3.5 or MW < 400, sLogP < 3, rotatable bonds < 6 (no long chains, < 4 open-chain atoms), aromatic rings < 3 (at least one heteroaromatic)
  • Balanced diversity, no singletons: 107 572 Murcko frameworks, > 5 molecules/framework, 92 % has < 100 molecules/framework
  • No toxic or unwanted groups. Filters applied: PAINS, NO2, CN, ester, triflate, sulfoxide, open-chain sulfide, terminal alkyne, carbamate, Boc-, Fmoc-, aryl/alkyl bromide/iodide, aldehyde, 2-halo pyridine/pyrimidine, oxamides
