Facile synthesis of the azocino[4,3-b]indole framework of strychnopivotine and other Strychnos alkaloids
(Springer New York LLC, 2016)
[Figure not available: see fulltext.]A new synthetic route to the 1,5-methanoazocino[4,3-b]indole is described. The aim of the present study is to provide a tetracyclic skeleton for the synthesis of pentacyclic Strychnos ...
UPLC versus HPLC on drug analysis: Advantageous, applications and their validation parameters
(2013)
Liquid chromatography (LC) is a separation technique used in many different areas to aid the identification and quantification of substances in various matrices. LC techniques with various detection modes have been widely ...
Separation and elution order of the enantiomers of some beta-agonists using polysaccharide-based chiral columns and normal phase eluents by high-performance liquid chromatography
(Elsevier B.V., 2016)
In this study separation of enantiomers of 8 chiral ?-agonists were studied on 6 polysaccharide-based chiral columns in polar-organic and alcohol-hydrocarbon mobile phases. No separation of enantiomers was observed on any ...
Solvent effects on pKa values of some substituted sulfonamides in acetonitrile-water binary mixtures by the UV-spectroscopy method
(2009)
The examination of the dissociation constants of sulfonamides is essential in drug-design studies and in explaining the biopharmaceutical properties of substances. The dissociation constants of ten common human and veterinary ...
Determination of dissociation constants of folinic acid (leucovorin), 5-fluorouracil, and irinotecan in hydro-organic media by a spectrophotometry method
(2010)
In this study, a multiwavelength spectrophotometry method was used for the determination of the dissociation constants of drugs used for treatment of colorectal cancer, folinic acid (leucovorin), 5-fluorouracil, and ...
Spectroscopic and thermal properties of newly mixed azocalix[4]arene ester derivatives
(Elsevier B.V., 2014)
The mono-, di-, tri-, and tetra-acryloyl esters of p-chloroazocalix[4]arene which include the first examples of mixed azo ester dyes were synthesized by reacting acryloyl chloride with sodium salts of p-chloroazocalix[4]arene ...
The photo-electrical properties of the p-Si/Fe(II)-polymeric complex/Au diode
(2013)
In this study, the Schiff base monomer was prepared by a common condensation method of salicylaldehyde and (E)-3-amino-4-((3-bromophenyl)diazenyl)-1H-pyrazol-5-ol. The poly(Schiff base) was synthesized from the oxidative ...
Carbon quantum dots co-catalyzed with multiwalled carbon nanotubes and silver nanoparticles modified nanosensor for the electrochemical assay of anti-HIV drug Rilpivirine
(Elsevier B.V., 2019)
In this study, a novel and sensitive voltammetric nanosensor has been developed for the first time, for the detection of Rilpivirine based on amine-functionalized multiwalled carbon nanotubes (NH 2 -fMWCNT) with Ag ...
The redox mechanism investigation of non-small cell lung cancer drug: Erlotinib via theoretical and experimental techniques and its host–guest detection by β-Cyclodextrin nanoparticles modified glassy carbon electrode
(Elsevier B.V., 2019)
Erlotinib (ERL) is a tyrosine kinase inhibitor which prevents growing of cancer cells. The electrochemical oxidation mechanism of ERL was studied in details using cyclic voltammetry. Cyclic voltammetry, differential pulse ...
Fabrication and characterization of magnetite-gadolinium borate nanocomposites
(Elsevier Ltd, 2017)
Soft ferromagnetic magnetite (Fe3O4)-gadolinium borate nanocomposites have been prepared via a facile hydrothermal approach by using Fe3O4, borax (BX) or boric acid (BA) and a simple Gd(III) salt. The products obtained by ...
