ENAMINE SUPPORTED MOLECULAR MODELLING COMPETITION FEATURED IN NATURE SCIENTIFIC REPORTS
December 10, 2015

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).

 

Enamine’s application to horizon 2020 selected for funding
August 28, 2015

Application "Peptidomimetics with photocontrolled biological activity" has been selected for funding in Horizon 2020 - the biggest EU research and innovation program ever (Call: H2020-MSCA-RISE-2015, Topic: MSCA-RISE-2015). Enamine acts as the coordinator in the joined project cooperating with the University Chemical Laboratory of University of Cambridge (UK), Department of Molecular Biophysics of Karlsruhe Institute of Technology (Germany), and Organic Synthesis Methodology Group of Latvian Institute of Organic Synthesis (Latvia). Overall funding will exceed 688,000 euro during 4 years, starting from 2016.

The expertise, resources and specific knowledge of all participating parties will be combined to achieve a breakthrough in design, synthesis and application of peptide analogues (peptidomimetics) possessing photo-controlled biological activities, with special emphasis on anti-microbial and anti-cancer activities. The main idea behind the Project consists in chemical incorporation of artificial photo-controllable Building Blocks into known biologically active peptides by replacing their natural Building Blocks – the amino acid residues. Such modification would provide photocontrolled peptidomimetics which can reversibly change their structure between two different photo-forms upon irradiation with light of different wavelength. The participating parties possess general know-how for design of the peptidomimetics which can exist in two photo-forms, biologically active and inactive ones, reversibly interconvertible by light of different wavelength. This opens a possibility to convert inactive peptidomimetics to active compounds by irradiation with physiologically benign light directly in tissues with very high spatiotemporal precision and can be a fundamental basis of new therapeutic strategies. The research staff exchange and other activities planned under the Project will be dedicated to accomplish four complementary work packages: (i) carrying out pharmacokinetic and toxicity studies of the photocontrolled peptidomimetics synthesized by the parties previously; (ii) evaluation of novel photocontrolled Building Block chemotypes for their compatibility with peptides; (iii) creation of new photocontrolled peptidomimetics, especially based on the novel Building Blocks and the know-how developed by the parties (e.g. using “stapled peptides” technology); (iv) multidisciplinary training of the researchers whose future work will be aimed at further development of the most advanced photocontrolled peptidomimetics as drugs suitable for photodynamic therapy.

A paper by Enamine scientists has been highlighted in “Chemical & Engineering News”
April 28, 2014

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 2014, 92 (17)

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.

 

A Very Important Paper by Enamine scientists
March 28, 2014

Babii, O.; Afonin, S.; Berditsch, M.; Reiβer, S.; Mykhailiuk, P. K.; Kubyshkin, V. S.; Steinbrecher, T.; Ulrich, A. S.; Komarov, I. V., Controlling Biological Activity with Light: Diarylethene-Containing Cyclic Peptidomimetics. Angew. Chem. Int. Ed. 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.

March 14, 2014

336 Azides and alkynes have been selected from Enamine’s catalogue 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.

 

Selected Building Block Series
February 3, 2014

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 catalogue 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.

Conformationally rigid amino acids
We offer a set of conformationally rigid proline analogues. This amino acid is frequently found in peptide b-turns, which play an important role in peptide receptor recognition and antigen determination ( J. Mol. Biol . 1988, 203, 221-232). It is highly probable that the bioisosteric replacement of proline analogues for proline in the known biologically active peptides/drugs may lead to new potential drug candidates.
