The influence of metals in biology has become more and more apparent within the past
century. Metal ions perform essential roles as critical scaffolds for structure and as catalysts …

A group of biologically active ligands: 5-(2hydroxyphenylide) barbituric acid (L 1), 5-(phenyl
azo) thiobarbituric acid (L 2) and 5-(phenyl azo) barbituric acid (L 3) and its complexes with …

Copper guanine and barbital complexes were prepared and characterized by elemental
analyses and spectral measurements. The data typified the formation of stoichiometries 1: 1 …

The complexes of Barbital (Bal), Thiobarbituric acid thione (TBA), Thiobarbituric acid thiol (2-
TBA), 2-Thiouracil (TU) with Zr (IV) and Hf (IV) were prepared. The structures and mode of …

Abstract The standard (po= 0.1 MPa) molar energies of combustion, Δ c U mo, for the
crystalline 5-isopropylbarbituric and 2-thiobarbituric acids were determined, at the …

Sensors for detecting and distinguishing metals in a sample comprise phenol group-
containing azo dyes, the phenol group having one hydroxy involved in reversible metal ion …

The modification of minerals with metals can promote changes in their surface and,
consequently, in their physicochemical properties. Minerals could have played an important …

An expedient and tandem regioselective one-pot protocol for the sono-synthesis of bis-[1, 2,
4]-triazol-3-yl amines and bis-2-iminothiazolines from corresponding bis-1, 3-disubstituted …
