Gold(III) Complexes for Antitumor Applications: An Overview [PDF]

Chemistry – A European Journal, 2018
AbstractGold(III) complexes have emerged as a versatile and effective class of metal‐based anticancer agents. The development of various types of ligands capable of stabilizing the AuIII cation and preventing its reduction under physiological conditions, such as chelating nitrogen‐donors, dithiocarbamates and C^N cyclometalled ligands, has opened the ...

Synthesis and cytotoxicity study of gold(III) porphyrin complexes and their derivative in breast cancer cells

Journal of Saudi Chemical Society, 2021
Gold(III) [Au(III)] complexes exhibit potential anticancer activities. A series of Au(III) porphyrin complexes containing different meso-substituent groups (phenyl, methoxyphenyl, butyloxyphenyl, octyloxyphenyl, and decyloxyphenyl) was synthesized.

Biologically‐Active Gold(III) Complexes [PDF]

Metal-Based Drugs, 1998
A review is given of the background to and results of the succesful pharmacological testing of [AuX2(damp)] (X = Cl, OAc; damp = 2 − Me2NCH2C6H4) against a range of microbes, fungi and tumouts, culminating in in vivo xenografts of ZR‐1‐75. These are the first fully evaluated gold(III) complexes.

Dihaloperhaloaryl(triphenylarsine)gold(III) Complexes

Journal of Organometallic Chemistry, 1975
Abstract When C 6 Cl 5 AuAsPh 3 reacts with halogens, oxidation of the gold(I) complex and formation of X 2 Au(C 6 Cl 5 )AsPh 3 (X = Cl, Br, I) take place. However, when C 6 F 5 AuAsPh 3 reacts with halogens, oxidation is only observed in the case of Cl 2 , whilst I 2 (totally) and Br 2 (partially) split the AuC bond. This behaviour is contrary
