this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...

The interactions between platinum complexes and human serum albumin (HSA) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. Octahedral platinum (IV) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. In this study, the interaction between two Pt(IV) complexes ...

a-Amino Acid Esters, Peptide Esters, Platinum(IV) Complexes, "N NMR Spectra, Pt NMR Spectra The platinum(IV) complexes PtX4L2 (X = Cl, Br; 2 X = oxalate; L = glyOEt, glyglyOEt, gly-cleuOEt; 2 L = metOEt) have been obtained by oxidative addition of halogenes to platinum(II) compounds PtX2L2A high field shift of <3N (—50 ppm) is observed for the coordinated amino acid ligand of various platinum c...

Background and Objectives: Transition metal complexes possess a variety of biological and pharmacological activities, such as antitumor, antimicrobial, anti-inflammatory, anti-diabetic, and free radical scavenging. Many studies have been carried out on platinum-based chemotherapy agents, however, most attention has been paid to non-platinum metal-based agents in order to find different metal comp...

Although examples of nickel(ii), palladium(ii) and platinum(ii) N-heterocyclic tetracarbene complexes are known in the literature, particularly platinum(ii) tetracarbene complexes are rare. We developed a new synthetic route via biscarbene acetate complexes, which make homoleptic as well as heteroleptic platinum(ii) tetracarbene complexes accessible. The reported photoluminescence data show tha...

Platinum(II) complexes with rigid and electron donating ligands are efficient phosphorescent emitters at room temperature. However, the excited-state lifetimes of these are, in general, relatively long. This problem, which can result degradation emitter, be overcome by exploiting natural tendency platinum to form metallophilic interactions aggregates. Herein, we report platinum(II) bimetallic 1...

two newly-created water-soluble complexes of palladium(ii)/platinum(ii)-dithiocarbamate, [pd/pt(phen)(pyr-dtc)]no3 (phen = 1,10-phenanthroline and pyr-dtc = pyrrolidinedithiocarbamate) were synthesized. also, their chemical characteristics are reported in the current research paper. in these complexes, the dithiocarbamato ligand coordinates to pt(ii) or pd(ii) center with two sulfur atoms as bi...

The impressive impact of cisplatin on cancer on one side and severe side effects, as well as the development of drug resistance during treatment on the other side, were the factors motivating scientists to design and synthesize new more potent analogues lacking disadvantages of cisplatin. Platinum(IV) complexes represent one of the perspective groups of platinum-based drugs. In this review, we ...
