Abstract
Cisplatin is widely used as anticancer drugs, and DNA is considered as the main target. Considering its high affinity towards cysteines and the important role of cystine containing proteins, we applied a competitive activity-based protein profiling strategy to identify protein cysteines that bind with cisplatin in HeLa cells. Living cells were treated with cisplatin at cytotoxic concentrations, then the protein was extracted. After labeling with desthiobiotin iodoacetamide (DBIA) probe, protein was precipitated, digested and isotopically labeled, subsequently the peptides were combined, and the biotinylated cysteine-containing peptides were enriched and quantified by LC-MS/MS. A total of 3571 peptides which originated from 1871 proteins were identified using the DBIA probe. Among them, 46 proteins were screened as targets, including proteins that have been identified as binding proteins by previous study. A novel cisplatin target, calpain-1 (CAPN1), was identified and validated as binding with cisplatin in vitro.

Abstract
A systematic study of the effect of phosphine and bis-phosphine ligands in the interaction of NiII, PdII, and PtII complexes with two classes of zinc fingers was performed. The Cys2His2, finger 3 of specific protein-1, and the Cys2HisCys C-terminal zinc finger of nucleocapsid protein 7 of the HIV-1 were used as models of the respective class. In general, phosphine ligands favor the metal binding to the peptide, although the bis-phosphine ligands produce more specific binding than the monodentate. In the case of nickel complexes, the interaction of NiII ions with the sequence SKH, present in Cys2His2, results in hydrolysis, contrasting to the preferred zinc ejection produced by the NiII complexes with chelating phosphines, producing Ni(bis-phosphine) fingers. In the absence of the SKH sequence, zinc ejection is observed with the formation of nickel fingers, with reactivity dependent on the phosphine. On the other hand, Pd(phosphines) produces Pd2 fingers in the case of triphenylphosphine with the phosphine coordinated as intermediate species. The bis-phosphine ligands produce very clean spectra and a stable signal Pd(bis-phosphine)finger. Interestingly, phosphines produce very reactive platinum complexes, which eject zinc and promote peptide hydrolysis. The results reported here are relevant to the understanding of the mechanism of these interactions and how to modulate metallocompounds for zinc finger interference.

Abstract
Cis-diamminedichloroplatinum(II) (cisplatin) is a widely used metal-based chemotherapeutic drug for the treatment of cancers. However, intrinsic and acquired drug resistance limit the efficacy of cisplatin-based treatments. Increased production of intracellular thiol-rich molecules, in particular metallothioneins (MTs), which form stable coordination complexes with the electrophilic cisplatin, results in cisplatin sequestration leading to pre-target resistance. MT-1/-2 are overexpressed in cancer cells, and their expression is controlled by the metal response element (MRE)-binding transcription factor-1 (MTF-1), featuring six Cys2His2-type zinc fingers which, upon zinc metalation, recognize specific MRE sequences in the promoter region of MT genes triggering their expression. Cisplatin can efficiently react with protein metal binding sites featuring nucleophilic cysteine and/or histidine residues, including MTs and zinc fingers proteins, but the preferential reactivity towards specific targets with competing binding sites cannot be easily predicted. In this work, by in vitro competition reactions, we investigated the thermodynamic and kinetic preferential reactivity of cisplatin towards human Zn7MT-2, each of the six MTF-1 zinc fingers, and the entire human MTF-1 zinc finger domain. By spectroscopic, spectrometric, and electrophoretic mobility shift assays (EMSA), we demonstrated that cisplatin preferentially reacts with Zn7MT-2 to form Cys4-Pt(II) complexes, resulting in zinc release from MT-2. Zinc transfer from MT-2 to the MTF-1 triggers MTF-1 metalation, activation, and binding to target MRE sequences, as demonstrated by EMSA with DNA oligonucleotides. The cisplatin-dependent MT-mediated MTF-1 activation leading to apo-MT overexpression potentially establishes one of the molecular mechanisms underlying the development and potentiation of MT-mediated pre-target resistance.

Abstract
Gold(i)-phosphine "auranofin-like" compounds have been extensively explored as anticancer agents in the past decade. Although potent cytotoxic agents, the lack of selectivity towards tumorigenic vs. non-tumorigenic cell lines often hinders further application. Here we explore the cytotoxic effects of a series of (R3P)AuL compounds, evaluating both the effect of the basicity and bulkiness of the carrier phosphine (R = Et or Cy), and the leaving group L (Cl-vs. dmap). [Au(dmap)(Et3P)]+ had an IC50 of 0.32 μM against the CEM cell line, with good selectivity in relation to HUVEC. Flow cytometry indicates reduced G1 population and slight accumulation in G2, as opposed to auranofin, which induces a high population of cells with fragmented DNA. Protein expression profile sets [Au(dmap)(Et3P)]+ further apart from auranofin, with proteolytic degradation of caspase-3 and poly(ADP-ribose)-polymerase (PARP), DNA strand-break induced phosphorylation of Chk2 Thr68 and increased p53 ser15 phosphorylation. The cytoxicity and observable biological effects correlate directly with the reactivity trend observed when using the series of gold(i)-phosphine compounds for targeting a model zinc finger, Sp1 ZnF3.

Abstract
Zinc finger proteins are one of the most abundant families of proteins and present a wide range of structures and functions. The structural zinc ion provides the correct conformation to specifically recognize DNA, RNA and protein sequences. Zinc fingers have essential functions in transcription, protein degradation, DNA repair, cell migration, and others. Recently, reports on the extensive participation of zinc fingers in disease have been published. On the other hand, much information remains to be unravelled as many genomes and proteomes are being reported. A variety of zinc fingers have been identified; however, their functions are still under investigation. Because zinc fingers have identified functions in several diseases, they are being increasingly recognized as drug targets. The replacement of Zn(ii) by another metal ion in zinc fingers is one of the most prominent methods of inhibition. From one side, zinc fingers play roles in the toxicity mechanisms of Ni(ii), Hg(ii), Cd(ii) and others. From the other side, gold, platinum, cobalt, and selenium complexes are amongst the compounds being developed as zinc finger inhibitors for therapy. The main challenge in the design of therapeutic zinc finger inhibitors is to achieve selectivity. Recently, the design of novel compounds and elucidation of the mechanisms of zinc substitution have renewed the possibilities of selective zinc finger inhibition by metal complexes. This review aims to update the status of novel strategies to selectively target zinc finger domains by metal complexes.

Abstract
We report the migration of platinum ligand unit {Pt(en)}2 (en = ethylenediamine) on a short peptide during collision-induced dissociation fragmentation combined with the characterization of the same species by 2D [1H,15N] HSQC (Heteronuclear Single Quantum Coherence) NMR spectroscopy. The NMR spectrum showed that the cysteine is platinated while the MS/MS (Tandem mass spectrometry) showed the platination at glutamic acid. Our results provide the first experimental evidence of platinum migration on peptide during collision-induced dissociation.

Abstract
Platinum (Pt)-based antitumor agents have been effective in treating many human malignancies. Drug importing, intracellular shuffling, and exporting—carried out by the high-affinity copper (Cu) transporter (hCtr1), Cu chaperone (Ato x1), and Cu exporters (ATP7A and ATP7B), respectively—cumulatively contribute to the chemosensitivity of Pt drugs including cisplatin and carboplatin, but not oxaliplatin. This entire system can also handle Pt drugs via interactions between Pt and the thiol-containing amino acid residues in these proteins; the interactions are strongly influenced by cellular redox regulators such as glutathione. hCtr1 expression is induced by acute Cu deprivation, and the induction is regulated by the transcription factor specific protein 1 (Sp1) which by itself is also regulated by Cu concentration variations. Copper displaces zinc (Zn) coordination at the zinc finger (ZF) domains of Sp1 and inactivates its DNA binding, whereas Cu deprivation enhances Sp1-DNA interactions and increases Sp1 expression, which in turn upregulates hCtr1. Because of the shared transport system, chemosensitivity of Pt drugs can be modulated by targeting Cu transporters. A Cu-lowering agent (trientine) in combination with a Pt drug (carboplatin) has been used in clinical studies for overcoming Pt-resistance. Future research should aim at further developing effective Pt drug retention strategies for improving the treatment efficacy.
