The biological importance of p-aminobenzoic acid was recognized only in 1940 when Woods showed that the compound antagonized the bacteriostatic effects of sulfonamides (2). Later, p-aminobenzoic acid was found to be an essential part of the folic acid molecule (3, 4), and it now seems quite likely that the sole metabolic function of p-aminobenzoate is to serve as a precursor for the biosynthesi...

This paper aims to report the synthesis of two new organotin(IV) carboxylate derivatives, triphenyltin(IV) 4-aminobenzoate (2) and 4-nitrobenzoate (3) examine their antibacterial activity as a disinfectant. These compounds were prepared by reacting hydroxide (1) with 4-aminobenzoic acid 4-nitrobenzoic acid, respectively. Compound was obtained yellow solid yield 84.09% compound in form white 80....

A facile homogenous precipitation method has been developed for the synthesis of multifunctional, magnetic, luminescent nanocomposites with Fe(3)O(4) nanoparticles as the core and europium-doped yttrium oxide (Y(2)O(3):Eu) as the shell. The nanocomposites showed both super-paramagnetic behavior and unique europium fluorescence properties with high emission intensity. Their surface has been modi...

The behavior of 2-ethoxy-(4H)-3,1-benzoxazin-4-one (1) towards nitrogen nucleophiles, e.g. ethanolamine, aromatic amines (namely: p-toluidine, p-anisidine, p-hydroxyaniline, o-hydroxyaniline, o-bromoaniline, o-phenylenediamine, p-phenylenediamine, o-tolidinediamine) p-aminobenzoic acid, glucosamine hydrochloride, 2-aminonicotinic acid, 1-naphthalenesulfonic acid hydrazide, n-decanoic acid hydra...

We describe the synthesis of novel mononuclear and dinuclear copper complexes and an investigation of their behaviour in solution using mass spectrometry (ESI-MS and ESI-MS/MS) and in the solid state using X-ray crystallography. The complexes were synthesized from two widely used diacetylpryridine (dap) ligands, i.e. 2,6-diacetylpyridinebis(benzoic acid hydrazone) and 2,6-diacetylpyridinebis(2-...
