Synthesis and biological activity of new cycloalkylthiophene-Schiff bases and their Cr(III) and Zn(II) complexes
(Birkhauser Boston, 2010)
A series of some novel Ethyl 2-((1-hydroxynaphthalen-2-yl)methyleneamino)- 5,6-dihydro-4H-cyclopenta[b]thiopehene-3-carboxylate, Ethyl 2-((1- hydroxynaphthalen- 2-yl)methyleneamino)-4,5,6,7-tetrahydrobenzo[b]thiophene-3- ...
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 ...
Crystal structures and intermolecular interactions of two novel antioxidant triazolyl-benzimidazole compounds
(Maik Nauka-Interperiodica Publishing, 2015)
The crystal structures of 5-(2-(p-chlorophenylbenzimidazol-1-yl-methyl)-4-(3-fluorophenyl)-2,4-dihydro-[1,2,4]-triazole-3-thione (G6C) and 5-(2-(p-chlorophenylbenzimidazol-1-yl-methyl)-4-(2-methylphenyl)-2,4-dihydro-[1,2 ...
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 ...
A note on the generalized Matsumoto relation
(TUBİTAK, 2017)
We give an elementary proof of a relation, first discovered in its full generality by Korkmaz, in the mapping class group of a closed orientable surface. Our proof uses only the well-known relations between Dehn twists. © TÜBİTAK.
First order self-adjoint multipoint quasi-differential operators
(TÜBİTAK, 2018)
In this paper, using the Calkin-Gorbachuk method, the general form of all self-adjoint operators generated by first order linear singular multipoint quasi-differential expressions in the direct sum of weighted Hilbert ...
Some results on uniform statistical cluster points
(TUBİTAK, 2017)
In this paper, we present some results linking the uniform statistical limit superior and inferior, almost convergence and uniform statistical convergence of a sequence. We also study the relationship between the set of ...
