Novel biologically active polyurea derivatives and its TiO2-doped nanocomposites

Synthesis of novel, potentially biologically active dibenzosuberone derivatives.

Novel representatives of the important group of biologically active dibenzosuberone derivatives were prepared: 3,7-dibromo-5-(dimethylaminoethyl- oxyimino)-10,11-dihydro-5H-dibenzo[a,d]cyclohepta-1,4-diene (1), 3,7-dibromo-5-(3- dimethylaminopropylidene)-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (2) and 1,7- dibromo-5-(3-dimethylaminopropylidene)-10,11-dihydro-5H-dibenzo-[a,d]-cycloheptene (3)....

Highly Visible Light Active Ag@TiO2 Nanocomposites Synthesized by Electrochemically Active Biofilm: A Novel Biogenic Approach

Two biologically active thiophene-3-carboxamide derivatives.

The two title compounds, 2-([(1Z)-[4-(dimethylamino)phenyl]methylene]amino)-4,5-dimethyl-N-(2-methylphenyl)thiophene-3-carboxamide, C(23)H(25)N(3)OS, (I), and 2-([(1E)-[4-(dimethylamino)phenyl]methylene]amino)-N-(4-methylphenyl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide,C(25)H(27)N(3)OS, (II), show antibacterial and antifungal activities. The asymmetric unit of (II) contains two crystal...

Effect of Cinnamon and its Biologically Active Compounds on the Components and Symptoms of Metabolic Syndrome

Background and purpose: Metabolic syndrome refers to a set of diseases including insulin resistance, high blood glucose levels, obesity, high blood pressure, and dyslipidemia. The cinnamon plant is a member of the Lauraceae family and is considered a universal medicinal plant. Traditional medicine studies reported the therapeutic effects of this plant in the reduction of blood glucose levels, b...

A Comparison of Photocatalytic Activity of ‎TiO2 Nanocomposites Doped with Zn2+/Fe3+ ‎and Y3+ Ions

   TiO2 based nanocomposites (NCs) were synthesized using the co-precipitation/hydrolysis (CPH) method. The composition of the first set (TZF) and the second set (TY) of NCs were: TiO2.[ZnFe2O4]x (with x = 0.1 to 0.5), and TiO2.[Y2O3]x (with x = 0.1 to 0.5), respectively. NCs with average crys...
