    Enamine To Support IBM’s OpenPandemics COVID-19 Initiative With Unparalleled ...

    Enamine will provide chemical synthesis support for a global nonprofit research initiative OpenPandemics COVID-19, organized by Scripps Research and IBM, and aimed at rapidly identifying efficient new drugs against the coronavirus SARS-CoV-2. Enamine will be synthesizing any promising hits identified by the research team at OpenPandemics COVID-19 via large scale docking experiments.

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
