Abstract
Interaction of cis-[Pt(en)(H2O)2]2+ and [CuL(H2O)]2+, where L is 2-[bis(2-aminoethyl)amino]ethanol, with oxidized insulin B chain in molar ratio of 1 : 1, 1 : 2 and 1 : 3 at pH 2.5 and 40 degrees C has been investigated by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). The results show that the binding sites of the two complexes with oxidized insulin B chain are terminal NH2, imidazole groups of His5 and His10. The hydrolytic cleavage studies show that the [CuL(H2O)]2+, upon a pendant hydroxyl group of the ligand, selectively cleaves the peptide bonds at Gly8-Ser9, Asn3-Gln4 and Phe1-Val2, and the cis-[Pt(en)(H2O)2]2+ only cleaves the peptide bond at His10-Leu11. This is the first report of cis-[Pt(en)(H2O)2]2+-promoted cleavage of His-X peptide bond.

Abstract
In the 20 years, since the introduction of electrospray mass spectrometry (ESI-MS), the use of this technique in various fields of inorganic, organometallic, and analytical chemistry has been steadily increasing. In this study, the application of ESI-MS to the study of metal-ligand solution equilibria is reviewed (till 2004 included). In a first section, advantages and drawbacks of ESI-MS in this type of application are described. Subsequently, a list of ca. 300 studies is reported, in which ESI-MS was used to give number and stoichiometry of the species at equilibrium, or also to estimate their stability constants. All studies are classified according to the metal ions under examination. Other related applications, such as host-guest interactions and metal ion-protein binding studies, are briefly reviewed as well.

Abstract
Interaction of carboplatin with cytochrome c (Cyt. c) has been investigated by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). ESI-MS studies revealed that the ring-opened adducts of carboplatin with Cyt. c were formed in the stoichiometric ratio of 1:1 and 2:1 at pH 5.0 and 37 degrees C and in the stoichiometric ratio of 1:1 only at pH 7.0 and 37 degrees C. It was also found that Cyt. c could be cleaved by carboplatin at pH 2.5 and 50 degrees C. The cleaved fragments of Cyt. c were determined by ESI-MS and MS/MS analysis to be Glu66 approximately Met80, Ac-Gly01 approximately Met65, Glu66 approximately Glu104, Ac-Gly01 approximately Met80 and Ile81 approximately Glu104. The carboplatin prefers to anchor to Met65 first, then to Met80. To further confirm the binding site of Met, AcMet-Gly was used as the model molecule to investigate its interaction with carboplatin and its hydrolysis reaction. On the basis of species detected during the reaction monitored by ESI-MS, a possible pathway of the cleavage reaction was proposed.

Abstract
Reactions of two platinum(II) complexes, cis-[Pt(NH3)2(H2O)2]2+ (Pt1) and cis-[Pt(en)(H2O)2]2+ (Pt2), with several sulfur-containing peptides, have been investigated by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). The species produced in the reactions were detected with ESI-MS, and MS/MS analysis was performed to probe structural information. Collision-induced dissociation revealed different dissociation pathways for the main reaction products of the two platinum(II) complexes with the same peptides. The major difference is the prominent loss of ammonia ligand for complexes of Pt1 due to the strong trans effect of sulfur, whereas the loss of ethylenediamine (en) ligand from Pt2 complexes is less favored, reflecting the chelating effect of the bidentate ligand. Despite the differences in dissociation patterns, Pt1 and Pt2, in general, form structurally similar complexes with the same peptides. In the reactions with Met-Arg-Phe-Ala they both produce a N,S-chelate ring through the N-terminal NH2 and sulfur of the Met residue, and in the reactions with Ac-Met-Ala-Ser they bind to the sulfur of Met and deprotonate an amide nitrogen upstream from the anchor site. Both of them are able to promote hydrolysis of the peptides. In reactions with glutathione they both form four-membered Pt2S2 rings and Pt-S-Pt bonding through the bridging thiolate ligand, although the reaction rate is much slower for Pt2 due to steric hindrance of the en ligand.

Abstract
The composition and binding sites of cis-[Ru(II)(bpy)2]2+-bound sulfur-containing peptides of Met-Arg-Phe-Ala, glutathione and oxidized glutathione, and also histidine-containing peptide of oxidized insulin B chain, were investigated by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). The composition of Ru(II)-containing peptides was precisely determined by ESI-MS, zoom scan and simulation of isotope distribution patterns. MS/MS analysis shows that, in sulfur-containing peptides, the Ru(II) complex prefers to anchor to a carboxyl group, although some other potential binding sites of thiol, thioether and N-terminal amino groups present in these peptides, and in oxidized insulin B chain, Ru(II) first anchors to His10, then either to the hydroxyl group of Thr27 or to the carboxyl group of Ala30. Its secondary structure and microenvironment surrounding the potential binding sites may affect the binding ability of cis-[Ru(II)(bpy)2]2+ to oxidized insulin B chain.

Abstract
The pH- and time-dependent reactions of the anticancer drug cisplatin, cis-[PtCl(2)(NH(3))(2)], with the peptides Ac-Gly-Met-Gly-OH, Ac-Ser-Met-OH and Ac-Met-His-OH (Gly=glycyl, Met=methionyl, Ser=seryl, His=histidyl) at 313 K have been investigated by high-performance liquid chromatography, nuclear magnetic resonance and mass spectrometry. In the major equimolar reaction pathway for Ac-Gly-Met-Gly-OH, rapid anchoring at the methionine sulphur (kappaS) is followed by successive metalations of the methionine N(M) and glycyl N(G1) amide nitrogens in N-terminal direction to afford bidentate kappa(2)S,N(M) and tridentate kappa(3)S, N(M),N(G1) complexes. Cleavage of acetic acid at the second upstream amide bond is observed after 10 h leading to slow formation of [Pt(H-Gly-MetH(-1)-Gly-OH-kappa(3)S,N(M),N(G1))(NH(3))](+) at pH<6. [Pt(H-Ser-MetH(-1)-OH-kappa(3)S,N(M),N(S))(NH(3))](+) results from an analogous cisplatin-mediated regioselective hydrolytic cleavage reaction for Ac-Ser-Met-OH in moderately acid solution (pH<4). After passing through a minimum at pH 4.4, the concentration of the cleavage product in the reaction mixture after 500 h increases steadily on raising the pH and release of acetic acid is effectively quantitative for 7pH9.5. A competing mechanism involving nucleophilic attack of the serine side chain on the acetyl function can be inferred for pH>6 by the HPLC detection of a second intermediate kappa(3)S,N(M),N(S) species. In striking contrast, the reaction of cisplatin with Ac-Met-His-OH leads to release of acetylmethionine and formation of a final histidine product cis-[PtCl(H-His-OH-kappa(2)N3,N(H)) (NH(3))](+) at pH<6 by a kappaS-->kappa(2)S, N3-->kappa(3)S, N(H),N3-->kappa(2)N3,N(H)(H-His-OH) pathway.
