Available in PDF, EPUB and Kindle. Book excerpt: Selective cleavage of proteins is a common procedure in many biochemical applications ranging from standard protein sequencing to novel methods in proteomics and bioengineering. Few enzymes and synthetic reagents are available for this important task, but new chemical reagents with improved efficiency and adjustable selectivity are highly desired. Complexes of palladium(II) and platinum(Il), two chemically similar transition-metal ions, are new reagents for selective cleavage of peptides and proteins. The cleavage by Pd(II) complexes, such as [Pd(H2O)4]2 or cis-[Pd(en)(H2O)2]2+, consistently occurs in weakly acidic aqueous solutions at the amide bond involving the N-terminus of the residue preceding histidine and methionine residues, i.e., the X-Y bond in the sequence segments X-Y-Met-Z and X-Y-His-Z, where X, Y, and Z are any non-coordinating residues. As pH is raised to neutral, the cleavage becomes sequence-specific - only the X-Pro bond in X-Pro-Met-Z and X-Pro-His-Z sequences is cleaved because of the unique interplay between the anchoring residue and the proline residue preceding it. The cleavage by Pt(II) complexes, such as cis-[Pt(en)(H2O)2]2+, occurs exclusively at the peptide bond involving the C-terminus of methionine residues, i.e. the Met-Z bond. In studies with peptide substrates, we explain the exceptional proteolytic selectivity of Pd(II) and Pt(II) complexes by identifying the hydrolytically-active modes in which these metal ions bind to the side chains of the anchoring residues and to the polypeptide backbone. The selectivity of cleavage originates in the selectivity of the coordination - under the reaction conditions, both methionine and histidine residues can bind to the Pd(II) reagents, whereas only methionine residue can bind to the Pt(II) reagent. The mechanism of cleavage originates in the modes of coordination - the anchored metal ion can approach the scissile peptide bond and activate it toward hydrolysis. The studies with protein substrates confirmed the cleavage pattern observed with peptides, and demonstrated that the Pd(II) and Pt(II) complexes are well-suited for biochemical applications. The ability of these complexes to cleave proteins at relatively few sites, with explicable selectivity and good yields, bodes well for their growing use in biochemical and bioanalytical practice.

Available in PDF, EPUB and Kindle. Book excerpt: The results are reported of research which was undertaken (1) to determine the chemical shifts of cis and trans isomers of platinum(II) complexes in hope of gaining information about pi-bonding in the Pt-P bond, and to extend this study to palladium(II); (2) to determine trends which may exist within a series of ligands for the purpose of developing expressions that would enable calculation of chemical shifts for complexes; (3) to expand the knowledge of the chemistry of tertiary phosphine complexes of platinum(II) and palladium(II); and (4) to determine phosphorus-phosphorus coupling constants by preparing a complex of a chelating diphosphine (R2PCH2CH2PR'2) or by preparing a complex containing two different phosphines.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1 provides an overview of the oxidation of methane by platinum salts known as Shilov chemistry. This includes platinum complexes used for the selective oxidation of methane to methyl bisulfate. Attention is paid to model platinum complexes that have been synthesised to explore the oxidation of methane using dioxygen as the oxidant. Chapter 2 describes two sets of tridentate N donor ligands that have been synthesised. The first set contains 6,6"-disubsthuted-2,2/:6/,2"-terpyridine ligands, of these two new ligands 6,6"-di(methylamino)-2,2/:6/,2"-terpyridine and 6,6"-dimethoxy-2,2/:6/,2"-terpyridine have been synthesised and fully characterised. The second set contains non-terpyridine tridentate ligands. The synthesis and characterisation of novel cationic platinum(II) methyl complexes bearing these ligands is described in Chapter 3. The structures of some of these complexes have been determined by X-ray crystallography. Further, the reactivity of the complexes towards dioxygen is reported and how different reactivity is imparted by the different ligands is discussed. The ability of some of these platinum(II) methyl complexes to insert dioxygen into their M-Me bonds arises from the steric interaction between the Pt-Me ligand and the substituents in the 6- and 6"-positions on the terpyridine ligand. Chapter 4 describes a study into the mechanism of the insertion of dioxygen into a Pt-Me bond. This includes deuterium labelling experiments, which led to the discovery of the exchange of methyl ligands between platinum(II) and palladium(II) centres. A mechanism for this exchange involving the formation of a MII_MII dimer is proposed. In addition, the decomposition of a palladium(II) methylperoxo complex to give an intriguing new metallacyclic hemiacetal alkoxide complex is described. A possible mechanism for the formation of this new palladium(II) complex is discussed. The synthesis and characterisation of the new compounds discussed in Chapters 2-4 are reported in Chapter 5. 4.
