A Very Important Paper by Enamine scientists

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.

A paper by Enamine scientists has been highlighted in “Chemical & Engineering News”

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.

Click Chemistry brochure added to Selected Building Block series

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.
