Square planar Au(III), Pt(II) and Cu(II) complexes with quinoline-substituted 2,2′:6′,2″-terpyridine ligands: From in vitro to in vivo biological properties

European Journal of Medicinal Chemistry, 2021
Cancer is the second leading cause of death worldwide. Cisplatin has challenged cancer treatment; however, resistance and side effects hamper its use. New agents displaying improved activity and more reduced side effects relative to cisplatin are needed.

Chitosan Beads as Eco-Friendly Biosorbent for the Biosorption of Au(III) and Cu(II) from Aqueous Solutions

Environment-Behaviour Proceedings Journal, 2022
This work aimed to study the biosorption of metal ions by chitosan beads, conducted at room temperature by adding chitosan beads into a conical flask containing different initial pH. The flask was agitated, and the concentrations of metal ions were determined using inductively coupled plasma-optical emission spectrometry (ICP-OES).

Complexing Behaviour of 5-Amino-1,3,4-Thiazole-2-thiol. II. Complexes of Ni(II), Rh(I), Pd(II), Pt(II), Au(III) and Cu(II) [PDF]

Bulletin of the Chemical Society of Japan, 1975
Abstract Complexes of Ni(II), Rh(I) Pd(II), Pt(II), Au(III) and Cu(II) with 5-Amino-1,3,4-thiadiazole-2-thiol have been prepared. Probable structures have been proposed for the complexes on the basis of visible and infrared spectral and magnetic susceptibility data and results of chemical analysis.
