Three-component condensation of methyl 4-(furan-2-yl)- and 4-(thiophen-2-yl)-2,4-dioxobutanoates with aromatic aldehydes and 1,3-thiazol-2-amine afforded 5-aryl-4-(hetaren-2-ylcarbonyl)-3-hydroxy-1-(1,3-thiazol-2-yl)-2,5-dihydro-1H-pyrrol-2-ones. Reactions of the latter with hydrazine and phenylhydrazine gave pyrrolo[3,4-c]pyrazol-6-ones and 3-phenylhydrazones, while the corresponding oximes were obtained in reactions with hydroxylamine. © 2015 Pleiades Publishing, Ltd.

The effects of chronic exposure to moderate concentrations of ethanol were studied in cultured hippocampal neurons. Network activity, assessed by imaging of [Ca2+]i variations, was markedly suppressed following 5 days of exposure to 0.25-1% ethanol. The reduced activity was sustained following extensive washout of ethanol, but the activity recovered by blockade of inhibition with bicuculline. This reduction of network activity was associated with a reduction in rates of mEPSCs, but not in a change in inhibitory synaptic activity. Chronic exposure to ethanol caused a significant reduction in the density of mature dendritic spines, without an effect on dendritic length or arborization. These results indicate that chronic exposure to ethanol causes a reduction in excitatory network drive in hippocampal neurons adding another dimension to the chronic effects of alcohol abuse. © 2015 Elsevier Inc.

Rheological properties of mild pharmaceutical formulations (creams) with glucocorticosteroids, such as Triderm (Belgium), Akriderm GK (Russia) and Kanizon plus (India) were studied. The study revealed differences in the structural-strength properties of the medicines (viscosity, critical shear stress). The necessity of rheological investigations during development of generic medicines was shown.

A new, efficient, catalyst-free, one-pot, three-component method for the synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines using 3,5-diamino-1,2,4-triazoles, cyanamide, and triethyl orthoformate is developed. The reaction proceeds smoothly under microwave-assisted heating. Advantages of the method include using easily available reagents, short reaction times, and operational simplicity. © 2013 Elsevier Ltd. All rights reserved.

The amino substituted triazine ring was annelated to aminoazoles using a new effective synthetic procedure. The method of preparation involved initial formation of azolylformamidines in the reaction of aminoazoles with N,N-dimethylformamide dimethyl acetal followed by the triazine ring closure with cyanamide affording therefore fused aminotriazines. © 2013 The Japan Institute of Heterocyclic Chemistry.
