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.

Axxam S.p.A., a contract research and discovery company, announced today that an entirely new generation screening collection is now available for drug discovery programs: AXX^DIV2.0 made up with 240 000 carefully selected small molecules.

Enamine and Exquiron are announcing a multi-year collaboration wherby Exquiron is acquiring a large screening compounds libraries from Enamine.

Dr. Pavel MYKHAILIUK, CSO at Enamine, has become a finalist at European Young Chemist Award 2016. He gave a talk at 6th EuCheMS Chemistry Congress (Seville, Spain, September 11-15). The European Young Chemist Award 2016 is intended to showcase and recognise the excellent research being carried out by young scientists working in the chemical sciences.

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).

Following the success since 2012 the collaboration with Sanofi aiming at finding of new valuable hit series in most challenging screening campaigns has been extended.

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.
