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.

Discovery Diversity Sets

High-quality diverse library of latest compounds

10 560 and 50 240 compounds

The success of high throughput screening in finding decent starting points for drug discovery heavily depends on the quality of the compound library. Understanding of which compounds are desirable and which ones are to be avoided has been evolving rapidly over the last 15 years since introduction by Chris Lipinski his “Rule of 5”. The concepts of drug- and lead-likeness have been revised many times and complemented with MedChem refinement and PAINS exclusion filters. It was, however, commonly admitted that screening of the compound libraries designed using only appropriate molecular criteria does not guarantee identification of quality hits that can quickly and inexpensively furnish lead compounds. Researchers have begun to scrutinize selection of the compounds to screen. The screening libraries must bear an essential degree of novelty, possess contemporary lead-like properties and be built on “live” chemistry that can supply related chemical entities.

Only between 2014 and 2016 Enamine synthesized over 430 000 non-exclusive screening compounds, which feature our new diversity of Enamine-exclusive building blocks and scaffolds. Having the largest commercial screening collection in the world, Enamine remains the only library producer that keeps enhancing its collection with significant number of new compounds each year. The renowned Enamine quality of compounds has been distilled in the design of two Discovery Diversity Sets (DDS). They compose of 10 and 50 thousand highly diverse compounds produced only within last three years. Discovery Diversity Sets are based only on the lead-like compounds including representatives of all three screening collections of Enamine – HTS, Advanced, and Premium. The two sets do not overlap and deliver a total of 60 thousand compounds. The Discovery Diversity Sets are highly recommended for random screening against new as well as popular targets because they are based on diverse novel scaffolds and latest building blocks. The hits discovered are expected to easily yield lead compounds. They can be readily followed with analogues either from stock or from new syntheses. All building blocks are readily available from Enamine stock.

Key features

  • Novel compounds
  • No singletons, 3-5 compounds per cluster
  • 4 912 Bemis-Murcko frameworks (DDS 50)
  • No PAINS, only medchem friendly compounds
  • Express follow-up guaranteed

Comparative analysis of DDSs and commercially available compounds

74% of the compounds from DDS 10K and 70 % from DDS 50K are available exclusively at Enamine

Reference database of 16.8M commercially available compounds from 33 vendors were collected from Zinc and eMolecules.
