Mechanism of catalysis with binary and triple catalytic systems based on redox inactive metal (lithium) compound {LiSt+L2} and {LiSt+L2+PhOH} (L2=DMF or HMPA), in the selective ethylbenzene oxidation by dioxygen into -phenylethyl hydroperoxide is researched. The results are compared with catalysis by nickel-lithium triple system {NiII(acac)2+LiSt+PhOH} in selective ethylbenzene oxidation to PEH. The role of H-bonding in mechanism of catalysis is discussed. The possibility of the stable supramolecular nanostructures formation on the basis of triple systems, {LiSt+L2+PhOH}, due to intermolecular H-bonds, is researched with the AFM method.

Anti Inflammatory

Background.: Inflammation is a multifactorial process reflecting response of the organismto various stimuli and is associated to a number of disorders such as arthritis, asthma and psoriasis, which require long-lasting or repeated treat-ment. Objective.: The aim of this paper is to evaluate the anti-inflammatory activity of previous synthesized thiazole-based chal-cone derivatives. Method.: Chalcones were synthesized via Cliazen-Schmidt condensation1-(4-methyl-2-alkylamino)thiazol-5-yl) ethanone with corresponding aromatic aldehyde. For the evaluation of possible anti-inflammatory activity carrageneen mouse paw edema was used. Results.: Eight out of thirteen tested chalcones showed anti-inflammatory activity in range of 51-55%. Prediction of toxicity revealed that these compounds are not toxic. Conclusion.: In general, it can be concluded that these compounds can be used for further modifications in order to develop more active and safe agents.
