The formation equilibria for the binary complexes of Cu(II) with 1-aminocyclopropane carboxylic acid (ACC) and 3,3-bis(1-methylimidazol-2-yl)propionic acid (BIMP) were investigated. ACC and BIMP form the complexes 110, 120 and 11-1. The ternary complexes of Cu(II) with BIMP and biorelevant ligands as some selected amino acids, peptides and DNA constituents(More)
The interaction of 3,3-bis(1-methylimidazol-2-yl)propionate (BIMP) with dimethyltin(IV) dichloride (DMT), dibutyltin(IV) dichloride (DBT), and diphenyltin(IV) dichloride (DPT) is investigated at 25°C and 0.1 M ionic strength in water for dimethyltin(IV), and in a 50% dioxane-water mixture for dibutyltin(IV) and diphenyltin(IV). The stepwise formation(More)
BACKGROUND AND AIMS Hypertrophic scar is a form of abnormal wound healing process in which tissue repair regulating mechanism is disrupted. Transforming growth factor β1 has a particular importance in the fibrotic scarring response. Treatment of hypertrophic scar included many chemical, physical, and surgical options. Fractional CO2 laser devices have(More)
The acid-base and complex-formation equilibria of [Ru(H(2)dtpa)(H(2)O)], where dtpa = diethylenetriaminepentaacetate, with a series of bio-relevant ligands having various functional groups, viz. thiol, amine, imidazole and carboxylate, were investigated using potentiometric and spectrophotometric techniques. The pK(a) values for [Ru(H(2)dtpa)(H(2)O)] were(More)
