Abstract
In this DFT study, activities of 11 different N2O4, N2O3, and NO2 core containing Zr(IV) complexes, 4,13-diaza-18-crown-6 (I'N2O4), 1,4,10-trioxa-7,13-diazacyclopentadecane (I'N2O3), and 2-(2-methoxy)ethanol (I'NO2), respectively, and their analogues in peptide hydrolysis have been investigated. Based on the experimental information, these molecules were created by altering protonation states (singly protonated, doubly protonated, or doubly deprotonated) and number of their ligands. The energetics of the I'N2O4, and I'NO2 and their analogues predicted that both stepwise and concerted mechanisms occurred either with similar barriers, or the latter was more favorable than the former. They also showed that the doubly deprotonated form hydrolyzed the peptide bond with substantially lower barriers than the barriers for other protonation states. For NO2 core possessing complexes, Zr-(NO2)(OHH)(H2O/OH)n for n = 1-3, the hydroxyl group containing molecules were found to be more reactive than their water ligand possessing counterparts. The barriers for these complexes reduced with an increase in the coordination number (6-8) of the Zr(IV) ion. Among all 11 molecules, the NO2 core possessing and two hydroxyl group containing I'DNO2-2H complex was found to be the most reactive complex with a barrier of 28.9 kcal/mol. Furthermore, barriers of 27.5, 28.9, and 32.0 kcal/mol for hydrolysis of Gly-Glu (negative), Gly-Gly (neutral), and Gly-Lys (positive) substrates, respectively, by this complex were in agreement with experiments. The activities of these complexes were explained in terms of basicity of their ligand environment and nucleophilicity of the Zr(IV) center using metal-ligand distances, charge on the metal ion, and the metal-nucleophile distance as parameters. These results provide a deeper understanding of the functioning of these complexes and will help design Zr(IV)-based synthetic metallopeptidases.

Abstract
We report for the first time on the selective hydrolysis of a polypeptide system by a metal-substituted polyoxometalate (POM). Oxidized insulin chain B, a 30 amino acid polypeptide, was selectively cleaved by the Zr(IV)-substituted Wells-Dawson POM, K15H[Zr(α2-P2W17O61)2]·25H2O, under physiological pH and temperature conditions in aqueous solution. HPLC-ESI-MS, LC-MS/MS, MALDI-TOF and MALDI-TOF MS/MS data indicate hydrolysis at the Phe1-Val2, Gln4-His5, Leu6-Cys(SO3H)7, and Gly8-Ser9 peptide bonds. The rate of oxidized insulin chain B hydrolysis (0.45 h(-1) at pH 7.0 and 60 °C) was calculated by fitting the integration values of its HPLC-UV signal to a first-order exponential decay function. (1)H NMR measurements show significant line broadening and shifting of the polypeptide resonances upon addition of the Zr(IV)-POM, indicating that interaction between the Zr(IV)-POM and the polypeptide takes place in solution. Circular dichroism (CD) measurements clearly prove that the flexible unfolded nature of the polypeptide was retained in the presence of the Zr(IV)-POM. The thermal stability of the Zr(IV)-POM in the presence of the polypeptide chain during the hydrolytic reaction was confirmed by (31)P NMR spectroscopy. Despite the highly negative charge of the Zr(IV)-POM, the mechanism of interaction appears to be dominated by a strong metal-directed binding between the positively charged Zr(IV) center and negatively charged amino acid side chains.

Abstract
Cisplatin is a potent anticancer drug, which functions by cross-linking adjacent DNA guanine residues. However within 1 day of injection, 65-98% of the platinum in the blood plasma is protein-bound. It is generally accepted that cisplatin binds to methionine and histidine residues, but what is often underappreciated is that platinum from cisplatin has a 2+ charge and can form up to four bonds. Thus, it has the potential to function as a cross-linker. In this report, the cross-linking ability of cisplatin is demonstrated by Fourier transform ion cyclotron resonance (FTICR) mass spectrometry (MS) with the use of standard peptides, the 16.8 kDa protein calmodulin (CaM), but was unsuccessful for the 64 kDa protein hemoglobin. The high resolution and mass accuracy of FTICR MS along with the high degree of fragmentation of large peptides afforded by collisionally activated dissociation (CAD) and electron capture dissociation (ECD) are shown to be a valuable means of characterizing cross-linking sites. Cisplatin is different from current cross-linking reagents by targeting new functional groups, thioethers, and imidazoles groups, which provides complementarity with existing cross-linkers. In addition, platinum(II) inherently has two positive charges which enhance the detection of cross-linked products. Higher charge states not only promote the detection of cross-linking products with less purification but result in more comprehensive MS/MS fragmentation and can assist in the assignment of modification sites. Moreover, the unique isotopic pattern of platinum flags cross-linking products and modification sites by mass spectrometry.

Abstract
This work is focused on the computational studies of reactions of hydrated forms of cisplatin with sulphur-containing amino acids cysteine and methionine. First, the appropriate model for solvation of the examined complexes was searched for. The suggested procedure employs the B3LYP density functional, 6-311++G(2df,2pd) basis set with Stuttgart-Dresden pseudopotentials on heavy atoms, the D-PCM solvation model and the UAKS cavity which uses more realistic NPA partial charges instead of formal partial charges for platinum ligands. In the second part this model is applied to the evaluation of the Legendre transformed reaction Gibbs free energy of cisplatin with cysteine and methionine in solution at constant pH.

Abstract
Platinum therapeutic agents are widely used in the treatment of several forms of cancer. Various mechanisms for the transport of the drugs have been proposed including passive diffusion across the cellular membrane and active transport via proteins. The copper transport protein Ctr1 is responsible for high affinity copper uptake but has also been implicated in the transport of cisplatin into cells. Human hCtr1 contains two methionine-rich Mets motifs on its extracellular N-terminus that are potential platinum-binding sites: the first one encompasses residues 7-14 with amino acid sequence Met-Gly-Met-Ser-Tyr-Met-Asp-Ser and the second one spans residues 39-46 with sequence Met-Met-Met-Met-Pro-Met-Thr-Phe. In these studies, we use liquid chromatography and mass spectrometry to compare the binding interactions between cisplatin, carboplatin and oxaliplatin with synthetic peptides corresponding to hCtr1 Mets motifs. The interactions of cisplatin and carboplatin with Met-rich motifs that contain three or more methionines result in removal of the carrier ligands of both platinum complexes. In contrast, oxaliplatin retains its cyclohexyldiamine ligand upon platinum coordination to the peptide.

Hohage O, Sheldrick WS. Cisplatin mediates selective downstream hydrolytic cleavage of Met-(Gly)(n)-His segments (n=1,2) in methionine- and histidine-containing peptides: the role of ammine loss trans to the initial Pt-S(Met) anchor in facilitating amide hydrolysis. J Inorg Biochem 2006; 100:1506-13. [PMID: 16806482 DOI: 10.1016/j.jinorgbio.2006.03.017] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2005] [Revised: 01/13/2006] [Accepted: 03/31/2006] [Indexed: 11/25/2022]
Abstract
The pH- and time-dependent reactions of the antitumor drug cisplatin, cis-[PtCl(2)(NH(3))(2)], with the methionine- and histidine-containing pentapeptides Ac-Met-Gly-His-Gly-Gly-OH, Ac-Met-Gly-Gly-His-Gly-OH and Ac-Gly-Met-Gly-His-Gly-OH (Gly=glycyl, Met=L-methionyl, His=L-histidyl) at 313K have been investigated by high performance liquid chromatography, mass spectrometry and nuclear magnetic resonance. Cisplatin mediates a rapid "downstream" hydrolytic cleavage of the Met-Gly amide bond in weakly acid solution (pH < or =5) for all three peptides, leading to release of H-Gly-His-Gly-Gly-OH, H-Gly-Gly-His-Gly-OH and H-Gly-His-Gly-OH, respectively, and formation of kappa(2)S,N(M) chelate complexes of the methionine-containing residuals Ac-Met-OH or Ac-Gly-Met-OH. An alternative reaction pathway affords tridentate kappa(3)S,N(M),N(imidazole) macrochelates of the original pentapeptide following ammine loss. The downstream cleavage pathway is competitive with the likewise cisplatin-mediated upstream cleavage of the Ac-Gly linkage in the pentapeptide Ac-Gly-Met-Gly-His-Gly-OH. This leads to formation of both the kappa(3)S,N(M),N(G1) complex of H-Gly-Met-Gly-His-Gly-OH due to upstream cleavage and the analogous tridentate complex for H-Gly-Met-OH due to initial downstream loss of H-Gly-His-Gly-OH followed by upstream loss of acetic acid. As downstream cleavage is not observed for Ac-(Gly)(2)-Met-(Gly)(2)-OH under similar conditions, it may be concluded that rapid histidine imidazole substitution of the ammine ligand in trans-position to an anchoring methionine S atom must assist hydrolytic cleavage of the Met-Gly amide bond.
