Quantitative structure-retention relationship of selected imidazoline derivatives on alpha(1)-acid glycoprotein column
(Elsevier Science BV, Amsterdam, 2016)
The retention behaviour of 22 selected imidazoline drugs and derivatives was investigated on alpha(1)-acid glycoprotein (AGP) column using Sorensen phosphate buffer (pH 7.0) and 2-propanol as organic modifier. Quantitative ...
Evaluation of Anticancer and Antioxidant Activity of a Commercially Available CO2 Supercritical Extract of Old Man's Beard (Usnea barbata)
(Public Library Science, San Francisco, 2016)
There is a worldwide ongoing investigation for novel natural constituents with cytotoxic and antioxidant properties. The aim of this study was to investigate chemical profile and stated biological activities of the ...
Insight into the template effect of vesicles on the laccase-catalyzed oligomerization of N-phenyl-1,4-phenylenediamine from Raman spectroscopy and cyclic voltammetry measurements
(Nature Publishing Group, London, 2016)
We report about the first Raman spectroscopy study of a vesicle-assisted enzyme-catalyzed oligomerization reaction. The aniline dimer N-phenyl-1,4-phenylenediamine (=p-aminodiphenylamine, PADPA) was oxidized and oligomerized ...
On a practically solvable product-type system of difference equations of second order
(Univ Szeged, Bolyai Institute, Szeged, 2016)
The problem of solvability of the following second order system of difference equations z(n+1) = alpha Z(n)(a)w(n)(b), w(n+1) = beta w(n)(c)z(n-1)(d), n is an element of N-0, where a, b, c, d is an element of Z, alpha, ...
Antibacterial and cytotoxic activities of wild mushroom Fomes fomentarius (L.) Fr., Polyporaceae
(Elsevier Science BV, Amsterdam, 2016)
The antibacterial activity of cyclohexane, dichlormethane, methanol and aqueous extracts of tinder fungus Fomes fomentarius (L) Fr (Polyporaceae) was tested against 9 bacterial strains (Staphylococcus aureus, Staphylococcus ...
Synthesis of the vitamin E amino acid esters with an enhanced anticancer activity and in silico screening for new antineoplastic drugs
(Elsevier Science BV, Amsterdam, 2016)
Tocopherols and tocotrienols belong to the family of vitamin E (VE) with the well-known antioxidant properties. For certain alpha-tocopherol and gamma-tocotrienol derivatives used as the lead compounds in this study, ...
Quantitative structure-retention relationships applied to development of liquid chromatography gradient-elution method for the separation of sartans
(Elsevier Science BV, Amsterdam, 2016)
QSRR are mathematically derived relationships between the chromatographic parameters determined for a representative series of analytes in given separation systems and the molecular descriptors accounting for the structural ...
Formulation of hydrogel-thickened nonionic microemulsions with enhanced percutaneous delivery of ibuprofen assessed in vivo in rats
(Elsevier Science BV, Amsterdam, 2016)
The study investigated usage of hydrogel of an anionic polymer xanthan gum for design of ibuprofen-loaded hydrogel-thickened microemulsions (HTMs) from the nonionic oil-in-water microemulsion (M). Xanthan gum demonstrated ...
Application of the design of experiments in optimization of drug layering of pellets with an insight into drug polymer interactions
(Elsevier Science BV, Amsterdam, 2016)
This study consists of two experimental designs. Within the first one, suitable technique for application of model drug onto inactive pellets was evaluated and formulation and process parameters with greatest impact to ...
