Synthesis of Spiro-fused Hydropyrimidinthiones with Use of Thiobarbituric Acid

The conditions for the preparative synthesis of spiro-fused hydropyrimidinthiones based on carbonyl substrates and thiobarbituric acid were found. Schemes of condensation carbo- and heterocyclization are presented. Regio- and stereoselectiveness processes was established.

Exploration of Possibilities for Organic Selenides and Dihydroselenochromilium Salt Interaction with Diphenylpicrylhydrazyl

Higher fungi – basidiomycetes play significant role as food and biological subjects for establishing the regularities of the living systems’ operation, development and response to the different-nature effectors impact. Insufficient activity of the living organisms’ antioxidant system interfering the ability of overcoming the negative consequences of oxidative stress (excessive level of free radicals in cells) is believed to be a reason for the organisms aging and death.
