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!

News

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.

Press Release

Dear Colleagues, Customers, and Friends,

It has been 43 days.

Forty-three days with thousands of bombs, shells, and missiles fired out at our cities and villages, thousands of destroyed buildings, bridges, streets, thousands of killed people. And there are to be feared thousands of victims yet to come as the war continues with a new focus to the East of our country, the war for democracy to prevail against dictatorship and tyranny, the war of the civilized world against the paranoiac barbarians, the war of good against evil. Russia commits genocide against Ukrainians, terrorizes the population, and engages in looting. Nowadays after the crimes in Chernihiv and Kharkiv, after the massacre in Bucha, Irpin and Borodyanka, everybody understands: the world appears to be once again black and white these days and one can see clearly who stands on the side of Ukraine.

I am thankful to the countries and businesses that support Ukraine. I thank those of you who provide donations and help our refugees, everyone who decided to stop paying taxes and operation in Russia, and everyone who just spreads the truth and makes others aware of it. It is hard to overestimate the importance of knowing and feeling that we are not alone in our fight for freedom.

EnamineThe situation in Kyiv has significantly improved and normalized for the past 2 weeks, so is the west part of our country. We are glad to see that several countries are re-opening their embassies in Kyiv. The president of the European Commission, Ursula von der Leyen, will visit Kyiv in the coming days. This shows optimal level of safety for our employees notably, and that the city returns to normal life. Following the call of our President and Prime minister to resume operations where and when it is possible, in compliance with strict safety regulations ruled by our local authorities, we, Team Enamine including already over 300 chemists, have collectively decided to get back to work in Kyiv. Indeed, gradually, since not all the chemistry can be performed right now, e.g., we avoid performing large-scale synthesis. We also expect some delays with purification and delivery for the first period, being determined to solve these issues as soon as possible with the drastically improving situation. We confirm that a major part of our synthetic operations can be performed, and that our chemists and biologists are ready and motivated to work on your projects and tasks.

Now I personally address these words to you, our valued customers and supporters. Please kindly consider resuming ordering our products and services and let us just do in that manner what we love and are best at: the synthesis. Please help us to restart the work at our full steam on custom synthesis, FTE projects and synthesis of make-on-demand building blocks. We are delighted to continue working with our established customers and are most happy to start new collaborations as we are solicitated.

Continuing ordering our compounds and services is the best support because it allows us to operate and keep our employees, our business and Ukraine strong, beside the other key reason of expediting uniquely your valuable research programs with the Art of Enamine.

Thank you!

Slava Ukraini!

Andrey Tolmachov
Founder and CEO of Enamine

Press Release

Dear Customers, Dear Colleagues, Dear Friends,

The war in our country lasts more than 10 days. We have put on hold most of our operations in Kyiv and ask our customers to wait until this situation is resolved. We thank all of you for your patience. During this time, we have been able to estimate our resources, capabilities, and plan next steps to be done. Now I would like to highlight some of them:

News

We are glad to inform you that we have fully restored the scope of our building block catalog as it was before the 24th 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.

News

We are happy to inform you that we have successfully completed the relocation of our entire collection of screening compounds and started weighing compound samples since yesterday. All 3.5 million vials with dry compounds have been safely moved to our new facility in Sokal, a town near Lviv with a population of 20 000 people in the West of Ukraine, close to the Polish border.

News

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

Press Release

Kyiv, Ukraine, 22 November 2021. Recently, Prof. Magolan and coworkers from McMaster University (Hamilton, Ontario, Canada) reported that hexafluoroisopropyl sulfamate (HFIPS) is a convenient reagent for the sulfamoylation of alcohols and amines (Org. Lett. 2021, 23, 3373–3378). HFIPS has also been used for metal-catalyzed C–H aminations (J. Am. Chem. Soc. 2014, 136, 5783–5789) and for the synthesis of aziridines using silver catalysis (Synthesis 2018, 50, 4462–4470) or electrochemical conditions (Angew. Chem. Int. Ed. 2018, 57, 5695–5698). Enamine has adapted and scaled-up the published procedure to synthesize HFIPS and make it more accessible to scientists worldwide. The reagent is now available in Enamine’s catalogue in multigram quantities.
