Bis(selone) Complexes of Palladium(II), Platinum(II), and Singlecrystal Xray diffraction analysis reveals that 17 and 18 exist as [2+2] dinuclear selfassembled 24membered metallamacrocycles, while the spectroscopic data for the gold(III) complex 19 indicate that it exists as a new organogold(III) bromide, where a Chemical biology of anticancer gold(III) and gold(I) complexesGold complexes have recently gained increasing attention in the design of new metal-based anticancer therapeutics. Gold(III) complexes are generally reactive/unstable under physiological conditions via intracellular redox reactions, and the intracellular Au III to Au I reduction reaction has recently been traced by the introduction of appropriate fluorescent ligands.

In vitro Biological Activities of Gold(I) and Gold(III The aim of this research is to evaluate for the first time the in vitro leishmanicidal activity and inhibition of glucosidase and glucuronidase of new gold(I) and gold(III) complexes involving Nheterocyclic carbene (NHC) ligands, with the general formula [Au(X) n (NHC)R 2][BF 4] (X=Cl, OAc, R=various aromatic and aliphatic substituents).

In vitro biological activities of gold(I) and gold(III

Jan 01, 2018 · The aim of this research is to evaluate for the first time the in vitro leishmanicidal activity and inhibition of alpha-glucosidase and beta-glucuronidase of new gold(I) and gold(III) complexes involving N-heterocyclic carbene (NHC) ligands, with the general formula [Au(X)(n)(NHC) R-2][BF4] (X= Cl, OAc, R= various aromatic and aliphatic substituents). New bipyridine gold(III) dithiocarbamate-containing We synthesized, characterized and tested in a panel of cancer cell lines, nine new bipyridine gold(III) dithiocarbamate-containing complexes. In vitro studies demonstrated that compounds 1, 2, 4, 5, 7 and 8 were the most cytotoxic in prostate, breast, ovarian cancer cell lines and in Hodgkin lymphoma cells with IC50 values lower than the reference drug cisplatin.
