San Francisco, USA, and Kyiv, Ukraine, March 6 2023. OpenBench, the first success-driven service for small molecule hit discovery, and Enamine, the world’s leading provider of astronomical numbers of compounds for biological screening, today announced the extension of their collaboration to enrich global early discovery efforts.

Barcelona, Spain, and Kyiv, Ukraine, 15 December 2022. Pharmacelera, the leading provider of computational tools for hit discovery, and Enamine, the developer of REAL Database – the world’s largest virtual library of highly feasible compounds, have announced a partnership to jointly provide an efficient solution for hit finding. Ultra-large chemical libraries are observed as one of the key paradigms to access an unexplored chemical space. How to traverse these enormous spaces accurately is a research area that has raised the interest of the pharmaceutical industry, since finding novel hits with chemical diversity is a fundamental pillar in drug discovery.

We are excited to co-author a new article published in the journal Science: “Structure-based discovery of nonopioid analgesics acting through the α2A-adrenergic receptor”, resulting from a fruitful international collaboration involving:

Since our return to the labs 1 month ago, we have managed to restore and catch up with practically all our synthesis and stock operations. We are extremely grateful for your being with us during these difficult times. We were happy to receive your messages of strong support and orders, demonstrating your continuous trust in Enamine. It means a lot to all of us, and it helped our quick rebirth.

Now more than 400 chemists have returned to our labs, among whom 150 as FTE’s in your research projects. Each week more chemists join back their FTE team structures. In early 2022, the company made a strategic supply of reagents and solvents so that we can continue self-sufficient synthesis activities for many months. Furthermore, most recently, significant progress has been made in receiving again goods and starting materials in Ukraine. Our newly established small synthesis lab in Latvia operates now in parallel to the Kyiv-based ones and will be happy to welcome new FTE clients.

Our parallel synthesis lab is capable now of setting up 1 400 - 1 500 syntheses per day, the rate that allows the synthesis of a few thousand REAL Compounds in a 2-month project. There is no limitation to the library size to request. As we used to encounter difficulties in dealing with the end-of-the-year REAL Compound orders always arriving in numbers, we would like to encourage you to send your requests as soon as possible and book our optimally available capacities in advance!

Enamine chemists back on creative spree. A few latest additions to our Building Block catalog

Enamine has resumed internal synthesis programs targeting to replenish and expand our catalog of Building Blocks. The strategic goal is to replicate our stock of BBs and make it evenly represented in all our three warehouses: in the US, in Latvia, and in Ukraine. The first step in this direction was made when we shipped sizeable selections of building blocks to our stocks abroad. Now our chemists are busy in resynthesizing them.

All our stock catalogs including building blocks, screening compounds, fragments, and plated compound libraries are readily available for your analysis and fully operatable. Our delivery times improve every week!

As of today, 17 countries among which France, Italy, and Austria to name a few, along with the European Union have sent their diplomats back to Kyiv, reopening their embassies, a vote of confidence that the Russia’s assault against the Ukrainian capital city and its region is over. This important symbolic and solidarity step from our allies makes clear that the necessary safety in Kyiv is returning, while the Russians have decided to re-focus on the East of Ukraine.

From our side, we are continuing working at full throttle to contribute to restoring our beloved homeland and its economy. Over 350 chemists including 100 FTE’s in our clients’ research projects have been able to resume their programs in our laboratories in Kyiv. We appreciate tremendously your indefatigable support, commitment, and trust in us!

This week we are happy to announce that our compound management team has resumed the liquid handling replication of our compound libraries. Although some more time (2 weeks) is required to fully re-start the weighing of dry compound samples from our screening collection, we can already supply from our liquid stock various pre-plated compound libraries. In line with our last week’s announcement, our very first dry-ice shipment since nearly two months has just left Kyiv towards our logistics centre in Riga from where individual orders will be further distributed to multiple clients across the world.

We are also pleased to confirm that our biology department Bienta has fully resumed its operations and provision of integrated drug discovery support. All our research facilities and technical equipment are in perfect working condition. Currently, all our groups and units (high throughput screening, bioanalytical, mass spectrometry, and in vivo) are resuming their projects and are ready to start new ones. The in vivo group is restoring the population of its laboratory animals, which were saved in our in-house core breeding section thanks to our galvanized colleagues’ efforts.

SANTA FE, N.M., USA, & KYIV, Ukraine – September 9, 2021 – OpenEye Scientific and Enamine, a leading global provider of billions of new screening compounds to the drug discovery market, are partnering to enable faster and more accurate virtual screening of ultra-large compound libraries through access to innovative software.

Kyiv, Ukraine, January 16, 2023. Enamine Ltd., the world’s leading designer and supplier of screening compound libraries and building blocks, together with UORSY, a top Ukrainian chemical company producing products for early drug discovery, announced today the creation of a joint “Legacy” screening collection.

This morning, russia carried out another act of aggression, firing dozens of rockets at peaceful cities in Ukraine, including Kyiv. Another act of barbarian terrorism. Despite it, we stand firm and resilient.

We are glad to inform you that we have fully restored the scope of our building block catalog as it was before the 24^th of February war outbreak. The catalog lists over 238 000 off-the-shelf products. Such items are again offered in the various batch sizes reaching up to 100 grams in many cases to give you full scale of choice for your projects. Please visit https://enaminestore.com/catalog to make structure searches and order online.

The situation in Kyiv keeps improving day by day, shops and restaurants are re-opening and people are returning to their homes in a continuous stream. More and more chemists come back to their labs and resume their projects at Enamine. Currently, over 300 chemists are already back to work, and we estimate this number to grow up to 400-500 colleagues within the next couple of weeks. We have restored the synthesis of building blocks, REAL Compounds, as well as custom synthesis, including FTE research projects in our Kyiv’s facility. Along with our absolute capacity to resynthesize building blocks in larger amounts as before, the resumption of the supplies from Ukraine has allowed us to return 2.5-, 5-, and 10-gram amounts to our building block catalog. Following our contingency plan at the war outbreak, we completely switched to supplies from our warehouses in US and Latvia, both largely limited to the 1-gram batch size. Now, we are resuming supplies of the larger amounts from our Kyiv stock and via resynthesis! Please check our offer at https://enaminestore.com/.

The quick supply of the building blocks is crucial. Even though the infrastructure in Ukraine has been significantly damaged during the war and despite express courier services have been suspended for the time being, our logistics specialists have organized a 3-day ground transportation route from Kyiv to our EU-based site in Latvia. This means that delivery time from Ukraine to your lab will be cut down to around 7-10 days very soon. Delivery time from US and EU local stores is as always 1-2 days.

We are looking forward to receiving your new inquiries and orders! This is the best way you can help us.

Faithfully Yours,
Enamine Team
