The green synthesis of 5-(4-aminophenyl)-4-aryl-4H-1,2,4-triazole-3-thiol was achieved in four steps, In first step, 4-amino benzoic acid refluxed in ethanol along with catalyst Conc. Sulphuric acid to produce ethyl-4-amino benzoate I. Further compound I refluxed with hydrazine hydrate in ethanol to produce 4-amino benzohydrazide II. Compound II refluxed in ethanolic potassium hydroxide with ca...

The coordination behavior of three ligand precursors 2-[(2- pyridinylmethyl)amino]acetic acid hydrochloride, 4-[(2- pyridinylmethyl)amino]benzoic hydrochloride and 4-{[2-(pyridin-2- ylmethylamino)ethylamino]methyl}benzoic HL1?HCl- HL3?HCl, respectively, in copper(II) complexes is described. were characterized by elemental analysis, ESI mass spectrometry IR spectroscopy, as well X-ray structural...

The asymmetric unit of the title compound, C(12)H(12)N(2)·C(7)H(7)NO(2), contains two 3-amino-benzoic acid mol-ecules and two 1,2-bis-(4-pyrid-yl)ethane mol-ecules. In the two 1,2-bis-(4-pyrid-yl)ethane mol-ecules, the dihedral angles between the pyridyl rings are 2.99 (9) and 46.78 (8)°. In the crystal, the mol-ecules associate through amine and carboxyl group N-H⋯O=C inter-actions between one...

In the current work, azo ligand and its Pd (Ⅱ), Cd Zn (Ⅱ) Hg complexes were synthesized, characterized their spectroscopic characteristics studied. The new was synthesized from coupling reaction between 4,5-bis(4-methoxy phenyl)imidazole diazonium salt of 4-Amino benzoic acid in an alkaline medium at 0-5 ᵒC. metal prepared by metals chlorides. All compounds FT-IR, 1H-NMR, Mass spectral analysis...

1. Benzoic acid and p-nitrobenzoic acid were converted in the scorpion Palamnaeus into N(1)-benzoylagmatine and N(1)-p-nitrobenzoylagmatine. 2. Some benzoyl- and p-nitrobenzoyl-arginine were also formed and these compounds were probable precursors of the agmatine derivatives. 3. p-Nitrobenzoyl- and p-aminobenzoyl-arginine were formed in millipedes dosed with the aromatic acids. 4. Woodlice excr...

Benzoate competes with n-amino acids for n-amino acid oxidase and thus inhibits the activity of the oxidase (l-3). Monosubstituted benzoates, depending upon the substituent, have higher and lower affinities for the oxidase than has benzoate (2). Kojic acid, a Y-pyrone, likewise competitively inhibits the oxidase (4). The present report describes the inhibition of n-amino acid oxidase by certain...
