Study of metalation of thioredoxin by gold(I) therapeutic compounds using combined liquid chromatography/capillary electrophoresis with inductively coupled plasma/electrospray MS/MS detection. Anal Bioanal Chem 2024; 416:2819-2833.

Abstract
The reactivity of thioredoxin (Trx1) with the Au(I) drug auranofin (AF) and two therapeutic N-heterocyclic carbene (NHC)2-Au(I) complexes (bis [1-methyl-3-acridineimidazolin-2-ylidene]gold(I) tetrafluoroborate (Au3BC) and [1,3-diethyl-4,5-bis(4methoxyphenyl)imidazol-2-ylidene]gold(I) (Au4BC)) was investigated. Direct infusion (DI) electrospray ionization (ESI) mass spectrometry (MS) allowed information on the structure, stoichiometry, and kinetics of formation of Trx-Au adducts. The fragmentation of the formed adducts in the gas phase gave insights into the exact Au binding site within the protein, demonstrating the preference for Trx1 Cys32 or Cys35 of AF or the (NHC)2-Au(I) complex Au3BC, respectively. Reversed-phase HPLC suffered from the difficulty of elution of gold compounds, did not preserve the formed metal-protein adducts, and favored the loss of ligands (phosphine or NHC) from Au(I). These limitations were eliminated by capillary electrophoresis (CE) which enabled the separation of the gold compounds, Trx1, and the formed adducts. The ICP-MS/MS detection allowed the simultaneous quantitative monitoring of the gold and sulfur isotopes and the determination of the metallation extent of the protein. The hyphenation of the mentioned techniques was used for the analysis of Trx1-Au adducts for the first time.

Abstract
Capillary electrophoretic analyses benefit significantly from hyphenation to mass spectrometric techniques. While the coupling to ESI-MS is routinely performed, for example by using a coaxial sheath-flow interface, hyphenating it to inductively coupled plasma mass spectrometry is more technically challenging. We use a commercially available coaxial sheath-flow interface (CSFI) and a simple PTFE-based end-cap for easy, inexpensive CE-ICP-MS hyphenation with improved sensitivity and analytical performance compared to commercially available interfaces. We have optimized key nebulizer parameters such as capillary position, sheath liquid flow rate, and carrier gas flow rate, and compared the CSFI with a commercially available interface. In a set of proof-of-principle experiments employing the anticancer agent cisplatin it was demonstrated that the signal to noise response and sensitivity were considerably improved leading to detection limits for 195Pt of 0.08 μM.
