    Enamine is selected for Horizon 2020 global project “AIDD” ...

    Enamine Ltd., a leading chemical research organization and producer of the world’s largest collections of novel building blocks (225,000+) and screening compound libraries (2,740,000+), has joined the Advanced Machine Learning for Innovative Drug Discovery (AIDD) program, funded by the European Union within the framework of the Marie-Skłodowska-Curie Actions (MSCA) with a budget of Euros 3.93 million. The project, coordinated by Helmholtz Zentrum München,Germany, brings together fifteen institutions from eleven countries in addition to the University of British Columbia (Canada) to train sixteen PhD students in close collaboration with associated partners from the USA, Australia, China, Israel and other countries and develop next generation AI and Machine Learning (ML) models and systems for drug discovery.

Discovery Diversity Sets

High-quality diverse library of latest compounds

10 240 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.
