Self-assembly of an organocatalyst for the enantioselective synthesis of Michael adducts and α-aminoxy alcohols in a nonpolar medium
(2013)
A proline-thiourea host-guest complex is described as a self-assembled organocatalyst for the enantioselective Michael addition of aldehydes to nitroolefins and for the asymmetric ?-aminoxylation of both aldehydes and ...
Study of asymmetric aldol and Mannich reactions catalyzed by proline-thiourea host-guest complexes in nonpolar solvents
(2013)
A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed ...

Spectroscopic, antiproliferative and antiradical properties of Cu(II), Ni(II), and Zn(II) complexes with amino acid based Schiff bases
(Birkhauser Boston, 2014)
Novel six Cu(II), Ni(II), and Zn(II) complexes with Schiff bases derived from 4-aminobenzoic acid with terephtaldehyde and amino acids (glycine, ?-alanine). Structures have been proposed from elemental analysis, UV-Vis, ...
Optimization of the experimental conditions for macrolide antibiotics in high performance liquid chromatography by using response surface methodology and determination of tylosin in milk samples
(2011)
The simple, rapid and sensitive liquid chromatographic separation of five macrolides (tilmicosin, erythromycin, tylosin, roxithromycin and josamycin) widely used in food producing animals was developed. Response surface ...
Simultaneous determination and validation of some binary mixtures of antihypertensive drugs using ratio derivative spectrophotometric method
(Maik Nauka Publishing / Springer SBM, 2014)
Ratio derivative spectrophotometric technique is presented for the rapid, accurate and precise simultaneous determination of olmesartan medoxomil (OLM), hydrochlorothiazide (HCT), and zofenopril (ZOF) as well as HCT binary ...
A validated RP-LC method for salmeterol and fluticasone in their binary mixtures and their stress degradation behavior under ICH-recommended stress conditions
(Maik Nauka Publishing / Springer SBM, 2014)
Simple, accurate, precise and fully validated analytical methods for the simultaneous determination of salmeterol xinafoate and fluticasone propionate in combined dosage forms have been developed. These drugs were exposed ...
Determination of pKa values of some antipsychotic drugs by HPLC-correlations with the kamlet and taft solvatochromic parameters and HPLC analysis in dosage forms
(2013)
In this study, ionization constant (pKa) values were determined by using the dependence of the retention factor on the pH of the mobile phase for four ionizable drugs, namely, risperidone (RI), clozapine (CL), olanzapine ...
