NEW HYBRID PHENOXYL-NITROXIDES
An unique approach to the synthesis of the previously unknown hybrid phenoxyl-nitroxides based on derivatives of 2-aryl-4H-imidazole was developed.
Derivatives of the new class of radicals represents high melting crystalline substances, stable at ordinary conditions (they could be stored and handled in an oxygen atmosphere at room temperature during considerable period of time). Hybrid radicals characterized both stability of ordinary nitroxides and structural features of galvinoxyls. According to the X-ray analysis, the lengths of key bonds in the molecule of crystalline hybrid radical corresponds phenoxyl structure. At the same time, in the solution, as follows from the ESR spectra, large values of hfs constants on the nuclei of nitrogen aN1 = 5.27 G and aN3 = 0.63 G, as well as the g-value 2.0055 ÷ 2.0065 indicating a significant contribution of nitroxide moiety.
The synthesized radicals are interesting as potential bifunctional hybrid catalysts used for mild and selective oxidation of alcohols, as well as chelates for the preparation of mixed organometallic paramagnetic materials. New hybrid monomeric radicals can be used as basis for preparation of polymeric electroactive materials, analogues of poly(stirylgalvinoxyls), extensively developed materials for creation of flexible completely organic rechargeable thin-film batteries.

AGENTS FOR MEDICINE – NEW ANTI-PARKINSONIAN COMPOUND
New compound with high anti-Parkinsonian activity has been synthesized. The agent may be used for monotherapy of the disease.
The compound was synthesized from α-pinene, which is the main component of turpentine.
In comparison with existing medicine used for treating Parkinson disease such as L-Dopa (Levodopa) the agent is less toxic and doesn’t possess serious side effects associated with L-Dopa.
The compound is on the stage of preclinical investigation now.

Effective antiviral compound
According to an official statement by the World Health Organization smallpox was eradicated in 1980. However, the risk of contracting it remains. That is why in the world do not stop the search of effective antiviral compounds. One of them - NIOC-14 - developed by scientists of the N.N. Vorozhtsov Novosibirsk Institute of Organic Chemistry together with specialists from the State Research Center of Virology and Biotechnology "Vector".
This compound inhibits the replication of orthopoxviruses in cell cultures at concentrations of several nanograms to several tens of nanograms per milliliter. This suggests good prospects for using this compound.
