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

A group of scientists led by Qubit cooperated on computer-driven de novo design of potential active molecules, with the subsequent synthesis of the most promising inhibitors by Enamine and their in vitro activity testing at Università degli Studi di Padova.

Please join us for a webinar "Hit Discovery for GPCRs: HTS or Virtual Screens?” presented by Guest Speaker, Carleton Sage, PhD, Vice President of Computational Sciences at Eurofins, Beacon Discovery on Thursday, June 24, 2021

We are happy to announce the start of Project ALISE supported by European Commission under Horizon 2020 MSCA-RISE. As the coordinator of the Project, Enamine is involved in the development of light-controllable antibody peptide conjugates pushing the boundaries of photopharmacology towards clinical applications.

Congratulations to Pavel Mykhailiuk, Chief Scientific Officer at Enamine, for receiving ERC Consolidator Grant funding for the Project: BENOVELTY - Saturated bioisosteres of benzene and their application in drug design.

The research will be carried out at Enamine Ltd in Ukraine, a global provider of chemical and biological services to biotech companies, academic institutions and research organisations.

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 (M^pro), 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.

Melatonin (MT) receptors are established drug targets for aligning circadian phase in disorders of sleep and depression. But there are only a few in vivo hits reported to date. Enamine scientists along with the scientists from UCSF, UNC, USC, and other institutions participated in the research study aimed to fill the gap in therapeutics of these receptors.

In continuation of our efforts to make affordable screening libraries that can quickly be supplied for screening, we have plated two new targeted libraries designed to bring high quality and novelty to your hit finding program. Both freshly-made libraries are ready for fast shipment within only one week in various formats including assay-ready plates.

Scientists at the UCSF, together with colleagues at the UNC, created the largest “docking-friendly” database of molecules, based on the Readily Accessible (REAL) compounds from Enamine. Practical validation of the new database was recently published in Nature magazine, demonstrating that it is capable of identifying extremely powerful and synthetically available new hits.

The demand for library synthesis at Enamine driven by the on-site access to the world’s largest and most reputable stock of building block has multiplied in 2018. We keep developing our preparative chromatography capabilities to sustain the drastically increasing number of compounds produced.

Our compound management team at Enamine is excited about the recent acquisition of the Echo® 550 Liquid Handler from Labcyte. This robotic superhero is expected to significantly speed up and notably precise compound handling, which is exactly an option needed for 2.5 Million+ compounds in stock. Screening libraries at Enamine are now more accessible, more customized and assay-ready to meet your exact needs in compound screening.

Accessing new chemistry for drug discovery has been recently facilitated by the approach developed by John Irwin et al. (DOI: 10.1021/acs.jcim.7b00316). Combination of Similarity Ensemble Approach (SEA) with the maximum Tanimoto similarity to the nearest bioactive was found to provide efficient prediction for all 400 million commercially available compounds in ZINC database including 340 million Enamine’s REAL compounds. You can access the files at https://zinc15.docking.org and http://files.docking.org/catalogs/20/enamine-v/. REAL compounds will be synthesized at Enamine on your request in less than 3 weeks with over 85% success rate!

Reactions conducted in autoclaves are very popular at Enamine because they allow synthesis of unique and novel building blocks that would not be doable otherwise. The key to their successful implementation into every day’s routine are quality pressure reactors that offer safe operations and are inexpensive at the same time.

Enamine is proud to announce that it has expanded its building blocks storage facility in Cincinnati totaling now 72 000 compounds. This allows Enamine to expedite logistics with its numerous US customers, offering a next-day delivery option for the majority of orders.

Enamine is announcing the expansion of its building blocks storage in its Cincinnati, logistic center, reaching currently more than 50 000 novel substances, with the plan to reach through its continued efforts at least 60 000 building blocks until the end of 2016. The company fulfills in this way the request of its numerous USA customers to expedite delivery time and fasten projects start.

Nature Scientific Report “Identification of potential inhibitors based on compound proposal contest: Tyrosine-protein kinase Yes as a target”

Compound proposal contest has been held at Tokyo Institute of Technology (Japan) on January 7 - March 20 2014 in a form of open innovation competition. Organized by the Initiative for Parallel Bioinformatics (IPAB) and supported by Enamine, it was aimed at identification of novel approaches for Computer Aided Drug Discovery (CADD) and finding novel unique hit molecules.

Enamine provided its world’s largest Screening Collection as a source of diverse compounds for the contest participants, who were instructed to select a maximum of 1 200 prioritized compounds towards a specific biological target - Tyrosine-protein kinase Yes. The contest resulted into 600 unique molecules selected by jury, from which 27 inhibitors were identified, yielding finally 7 potential hits.

Enamine’s Screening Compounds Collection is a unique product offering containing more than 2 000 000 diverse and distinct compounds in significant amounts (typically, 150 mg in stock).

Controlling Biological Activity with Light: Diarylethene-Containing Cyclic Peptidomimetics
Oleg Babii, Sergii Afonin, Marina Berditsch, Sabine Reisser, Pavel K. Mykhailiuk, Vladimir S. Kubyshkin, Thomas Steinbrecher, Anne S. Ulrich and Igor V. Komarov
Angewandte Chemie International Edition 2014 53 (13), 3392–3395

Enamine scientists in collaboration with research at Karlsruhe Institute of Technology (KIT, Germany) published a study on antibiotics activated by light. It deals with synthesis of analogues of the antimicrobial peptide gramicidin S which conformations can be switched by light. This property was rendered by incorporation in its structure of an amino acid designed based on a photoisomerizable diarylethene scaffold. The biological activity of the resulting peptidomimetics can be reversibly controlled by ultraviolet/visible light.

Success of Enamine’s innovative product pipeline and service portfolio is based on the commitment of the company to the scientific research. Enamine caries out and supports research projects within the company as well as off-site in collaboration with many academic centers in Ukraine and abroad. About 30 scientific papers were published by Enamine scientists in renowned scientific journals in 2013.

With development of on-line chemical directories acquiring necessary reagents and building blocks for day-to-day research activity has become a technical routine. Many thousands of building blocks are now available in the market and sub-structure search can efficiently provide a selection of reagents to buy. However, this approach might be limited. With over 80,000 building blocks synthesized and now available from our stock we are a recognized leader in the market. Our catalog features versatile building block classes and adds 1,000 products each month. Although they all are available for purchase through EnamineStore and many public or corporate chemical databases we wanted to gather together the most interesting and recently prepared building blocks to provide a series of useful guides to a novel and innovative chemistry. First five brochures have been published to highlight our rich collections of Advanced Morpholine Analogues, Bicyclic Aliphatic Amines, Fluorinated Aliphatic Amines, Isocyanates, Isothiocyanates, and Trifluoroethyl Carbamates, and Sulfonyl Chlorides and other Sulfonylating Agents.

Enamine is planning to change the numbering of products offered through screening collections in 2012. To facilitate compound tracking in different offerings and allow transparent identification of structures by their unique ID throughout various databases, the old identification method utilizing lot-related T-numbers will be ceased. According to the new identification system all structures referring to compounds offered by Enamine for screening will have unique Z-codes familiar to those who worked with REAL Database before. Existing T-codes will be supported for ordering purposes.

Over 51,000 low  molecular weight reagents are now available from our stock. To the best of our knowledge, with this amount of substances the company has become the world’s largest supplier of physically available building blocks. The considerable improvement of synthetic technologies at Enamine is pushing the limits of the stock update rate. Currently over 1,000 building blocks are added to the stock every month.

EnamineStore at www.enaminestore.com was completely updated – both content and interface were affected by following changes:

• new products added to catalog: except for stock Screening Compounds and Building Blocks now it is possible to search, browse and order feasible screening compounds (REAL DB) and Tangible Building Blocks
• new search features: one-click 'Find Analogs' option, advanced search wizard, search by a list of CAS numbers and more
• tracking and current statuses for orders placed on-line
• supplemental data on stock compounds updated in catalog
• new look of catalog and cart pages, color coding for compounds in different categories

Price of over 9 000 building blocks was reduced by 50% on average. Selected compounds were discounted by as much as 80%! The products affected by price reduction conform to high quality standards of Enamine and are available from stock. Over 1 500 building blocks from this set are also available for rush delivery in 1g batches. You can download the set of discounted building blocks as SDF, ISIS DB or PDF. Please visit EnamineStore to check current stock availability and order on-line.

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.

In a recent JACS paper several academic groups collaborated on discovery of novel covalent inhibitors using a library of 993 acrylamides and chloroacetamides sourced from Enamine’s covalent fragment collection. The design was focusing on mild electrophiles that were supposed to overcome the selectivity challenge. The library was characterized by a new high-throughput thiol-reactivity assay and screened against 10 cysteine-containing proteins. Potent and unique primary hits have been found in the majority (7 out of 10) of cases.

EU-funded project PELICO, under Enamine’s coordination, reports promising results in synthesis of peptides, their pharmacokinetic and toxicity studies, and coupling with photo-controlled building blocks to yield new photo-controlled peptidomimetics.

Enamine's chemists and biologists from Bienta just published an article in ACS Comb. Sci. describing design and synthesis of a new sulfonyl-fluoride-based covalent fragment library. The library was validated by screening against a model protease, trypsin, and some fragment hits were identified. See ACS website for more details.

Enamine Ltd, together with Elsevier, ChemSpace SIA, Institute of Organic Chemistry of National Academy of Sciences of Ukraine, and Kyiv Institute of Bioorganic Chemistry and Petrochemistry of National Academy of Sciences of Ukraine, are co-organizing The 18th European Symposium on Fluorine Chemistry to be held on August 7 - 12, 2016 in Hotel Ramada Encore Kyiv, Ukraine. Early bird registration for the event is now open for industrial and academic participants from around the world. Student participation is possible.

This year’s Symposium is a continuation of a long tradition of gathering research and industrial leaders in the field of fluorine science from all around the globe in order to discuss modern trends in fluorine research, present latest achievements and breakthroughs. The scope of the event will include application of fluorine in areas of drug discovery, material science, agrochemistry, energy storage and many others.

The main sub-sections are as following:

• Organic and Bio-Organic Fluorine Chemistry,
• Inorganic Fluorine Chemistry,
• Physical Fluorine Chemistry
• Industrial and Polymer Fluorine Chemistry.
• Other Areas of Fluorine Science

All interested industrial and academic organizations, individual scientists and students are welcome to register for participation in this year’s leading event on Fluorine.

Mykhailiuk, P. K. Generation of C₂F₅CHN₂ In Situ and Its First Reaction: [3+2] Cycloaddition with Alkenes Chem. Eur. J. 2014, 17, 5168. (Back Cover Picture)

Ritter, S. K. Diazoalkane Expands Fluorine Focus On Ethyl Groups Chemical & Engineering News, 92 (17), 2014.

Developing new methods for introducing fluorine into complex organic molecules has been all the rage during the past few years. Researchers preparing drug candidates and crop-protection chemicals typically seek to add a single fluorine atom or trifluoromethyl group and now have myriad ways to do so. But methods for adding longer, more lipophilic perfluoroalkyl groups, such as pentafluoroethyl, –C₂F₅, to complex molecules are relatively scarce. The approaches tend to be direct additions of C₂F₅ using organometallic transfer reagents and don’t utilize C₂F₅-containing building blocks.

Enamine scientists have developed a new building block for introducing C₂F₅ group into organic molecules. Pavel Mykhailiuk and colleagues safely generated the fluorinated diazoalkane, C₂F₅CHN₂, in situ from C₂F₅CH₂NH₂•HCl and NaNO₂. Authors demonstrated the utility of the reagent by using it in [3 + 2]-cycloadditions with mono- and disubstituted alkenes at room temperature to prepare perfluoroethylated pyrazolines with better than 95% conversion rates. Authors believe the diazofluoroalkane will also be as useful as other diazoalkanes for cyclopropanations, carbene insertions, and alkyne cycloadditions.

336 Azides and alkynes have been selected from Enamine’s catalog of over 90 000 Building Blocks. Their structures have been published in the Selected Building Block series. This brochure, the sixth in series, provides a useful guide to novel and innovative chemistry developed at Enamine that can find multiple applications in drug design. Cycloaddition reaction of azides and alkynes has been shown to smoothly provide excellent yields of 1,2,3-triazoles. It has been recognized as an outstanding example of “click chemistry” This reaction can be used to selectively synthesize both 1,4- and 1,5-substituted triazoles. Besides reaction with azides alkynes undergo many other cycloaddition reactions.

The new version of EnamineStore provides enhanced functionality to quickly search and purchase from catalogs of Enamine and UORSY (collectively over 10 million compounds). The following improvements have been realized besides changes in general form layouts:

Enamine announces opening of contract biology laboratory at its main research site in Kyiv, Ukraine. Enamine’s BioLab will be providing ADMET (absorption, distribution, metabolism, excretion and toxicity) and biomolecular screening services to expand Enamine’s chemistry-driven CRO capabilities into the biological support of early phase drug discovery projects.
Integration of the newly created contract biology lab with Enamine’s internationally renowned synthetic chemistry powerhouse and the vast screening compound repository creates a perfect combination for providing efficient and cost-competitive drug discovery services to the international pharmaceutical and biotech industry.

Solid-Phase Peptide Synthesis was launched by Enamine with a new PS3 Peptide synthesizer (Protein Technologies, Inc.). Small linear and cyclic peptides comprising 2 to 25 amino acid residues of both natural and unnatural origin can be prepared on 1-30 mg scale in a highly pure form (>95%). A large collection of proprietary unnatural amino acids including many conformationally constrained ones as well as ones containing fluorine substituents can be used to expand the variety of peptides. The example structures of peptides prepared with our new peptide synthesizer are listed below.

CF3-Labeled SAP analogue ( Angew. Chem. Int. Ed. 2008 , 47 , 5765 –5767 )

Recently Enamine has further improved the high-throughput synthesis workflow used for preparation of compounds offered through the REAL Database. Removal of production bottlenecks, application of optimized technological solutions and expansion of high performance preparative flash chromatography unit allowed us to shorten entire production cycle to 12-14 days. Currently we are able to produce up to 2,000 samples per month using this optimized procedure. 90% feasibility rate can be achieved after a single production cycle for typical compound sets. Compounds synthesized via the enhanced scheme can be delivered within 3 weeks after acceptance of an order.

As from October 2010 Enamine provides access to NMR and LC/MS data for stock compounds through EnamineStore on-line service. Available spectral data for a compound of interest can be downloaded in PDF format by clicking the "Download spectral data" link located in the "Details" dialog accessible from the catalog section (search results). The analytical data can be accessed by registered users only.

Starting from January 2010, Enamine starts offering screening compounds via three separate libraries: Advanced, HTS and Historical collection. Advanced collection will always contain only novel and recently synthesized compounds, thus clients who persistently monitor additions to Enamine stock will spend less time and efforts to find new structural motifs. HTS collection will continue to be an indispensable source of compounds for various screening needs, providing unparalleled choice of diverse chemotypes. Historical collection will contain compounds representing scientific heritage of major regional research groups and institutions, particularly interesting for research programs in agro-chemistry and material science.
