Unprecedented gold(i) bioconjugates bearing non-proteinogenic amino acid 4-mercaptoproline species as bioorganic ligands have been prepared. Firstly, the synthesis of Boc-Pro(SH)-OMe (1) has been accomplished by standard procedures. The subsequent reaction of 1 with [AuCl(PR3)] gives complexes Boc-Pro(SAuPR3)-OMe (PR3 = PPh3 (2), PPh2Py (3)). Starting from complex 2 several structural modifications have been performed, in addition to the incorporation of a different phosphine in 3, such as the…

Synthesis, Molecular Docking and Cytotoxic Activity Evaluation of Organometallic Thiolated Gold(I) Complexes
TLDR
The results indicated that 2a exhibited comparable cytotoxicity on investigated cell lines with cisplatin and showed a good anti-proliferative activity with IC50 of 19.46, 11.76 and 13.27 μM against A549, SKOV3 and MCF-7 cell lines, respectively.
Luminescent Re(I)/Au(I) Species As Selective Anticancer Agents for HeLa Cells.
TLDR
Antiproliferative studies in cancer cells, A549 and HeLa, showed a generalized selectivity toward HeLa cells for those heterotrimetallic species incubated at longer times (72 vs 24 h).
Gold(I) Complexes Bearing Alkylated 1,3,5-Triaza-7-phosphaadamantane Ligands as Thermoresponsive Anticancer Agents in Human Colon Cells
TLDR
The results suggest that this cytotoxic effect of gold derivatives with phosphanes derived from 1,3,5-triaza-7-phosphaadamantane (PTA) with long hydrocarbon chains and the homologous fluorinated chains is enhanced by hyperthermia and the presence of polyfluorinated chains.

Highly cytotoxic bioconjugated gold(I) complexes with cysteine-containing dipeptides.
TLDR
The complexes show an outstanding cytotoxic activity with IC50 values in the very low micromolar range and structure-activity relationship studies from the complexes open the possibility of designing more potent and promising gold(I) anticancer agents.

TLDR
Gold(I) complexes of imidazole and thiazole-based diphos type ligands were prepared and their potential as chemotherapeutics investigated and cytotoxic activity was assessed against three human cancer cell lines and a rat hepatoma cell line and correlated to the lipophilicity of the compounds.

TLDR
These gold compounds were characterized by a combination of NMR and infrared spectroscopy, microanalysis, and mass spectrometry; and in selected cases by single-crystal X-ray crystallography.
Synthesis of new gold(I) thiolates containing amino acid moieties with potential biological interest.
TLDR
The reaction of the gold(I) complex, which contains nicotinic acid thiolate, with several amino acid esters such as glycine methyl ester, has been characterized by X-ray crystallography, showing, in the second case, only one of the enantiomers, which proves that retention of the configuration after reaction occurs.

TLDR
Mechanistic experiments indicated that the inhibition of thioredoxin reductase (based on the covalent binding of a gold triethylphosphine fragment) might be involved in the pharmacodynamic behavior of this novel gold species.
Gold(I) carbene complexes causing thioredoxin 1 and thioredoxin 2 oxidation as potential anticancer agents.
TLDR
The compounds showed potent and selective TrxR inhibition properties in particular in cancer cell lines, and induced extensive oxidation of thioredoxins (Trxs), which was more relevant in the cancerous cells than in HEK-293T cells.
