Metal complexes of biologically important ligands, CXVI. Addition of carbanions from barbituric acid derivatives to unsaturated hydrocarbons in cationic complexes for the organometallic labelling of barbituric acid

Comparison of Serum Malondialdehyde Levels Determined by Two Different Methods in Patients With COPD: HPLC or TBARS Methods

“…11 The sensitivity and specificity of TBARS method currently in use may not be adequate because it is reported that some substances (eg, some metal ions and organic molecules), which may present in the serum medium except MDA, may cause chemical interference by forming complexes with TBA. 10,[15][16][17][18] Therefore, this method is also criticized because of its low specificity, sensitivity, and reproducibility. 19 Recently, HPLC, a more sensitive, specific, and reproducible method in determination of MDA, is preferred as an alternative method by a lot of researchers.…”

“…Furthermore, in this method, it is stated that TBA forms complexes with MDA and the other many subtrates such as metal ions and organic molecules. [8][9][10] Here, we propose to determine and discuss MDA levels in serum by using these 2 different methods both in the exacerbation and the stable period of COPD patients, and thereby compare the specificity, sensibility, and all other characteristics of these 2 methods.…”

A study on optimum transition state and tautomeric structures of a bis-heterocyclic monoazo dye

“…Azo compounds are quite colorful and have been extensively used in many technical applications such as coloring fibers, photo electronic applications, printing systems, optical storage technology, textile dyes as well as in many biological reactions [1][2][3][4][5][6][7][8][9][10]. Azo moieties have fungicidal and antibacterial properties and are used in the detection of trace metals in drinking water and food materials [11].…”

Synthesis and characterization of novel metal complexes of (pentulose-?-lactone-2,3-enedibenzoate barbituric acid) with some metal ions

“…A variety of transition metal complexes with barbiturates have been prepared owing to their important roles in clinical detection and identification of drug [1][2][3][4][5]. Masoud [6] reported the synthesis of copper complexes with azobarbituric and azothiobarbituric acids.…”
