Comproportionation of the platinum(0) complex Pt(PMe3)4 with the platinum(II) hexafluoroacetylacetonate complexes Pt(hfac)2 or [Pt(hfac)(PMe3)2][hfac] yields diplatinum species of stoichiometry [Pt2(μ-hfac)(PMe3)4][hfac], 1, and [Pt2(PMe3)6][hfac]2, 2, respectively. The NMR spectra and X-ray crystal structure of 1 show that the two platinum centers are chemically inequivalent; one is a square-p...

High-Grade Serous Ovarian Carcinoma (HGSOC) is the predominant histotype of epithelial ovarian cancer (EOC), characterized by advanced stage at diagnosis, frequent TP53 mutation, rapid progression, and high responsiveness to platinum-based-chemotherapy. To date, standard first-line-chemotherapy in advanced EOC includes platinum salts and paclitaxel with or without bevacizumab. The major prognos...

The aim was to compare the two most commonly recommended chemotherapy regimens (platinum-based chemotherapy and platinum-taxane combination) with non-platinum-based chemotherapy and those with no chemotherapy in a large nationwide and population-based cohort of patients with ovarian cancer with up to 17 years of follow-up. We studied 12,181 patients diagnosed with stages I-IV ovarian cancer at ...

The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solut...

The photolytic activation of palladium(II) and platinum(II) complexes [M(BPI)(R)] (R = alkyl, aryl) featuring the 1,3-bis(2-pyridylimino)isoindole (BPI) ligand has been investigated in various solvents. In absence oxygen, formation chloro [M(BPI)Cl] is observed chlorinated solvents, most likely due to degradation solvent HCl. reactivity toward oxygen studied both experimentally computationally....

INTRODUCTION CISPLATIN has been shown to have some activity in gastric cancer but its application is limited because of toxicity [ 11. In recent years, the search for platinum compounds with reduced toxicity has been the main goal in the development of platinum analogs. Based on available phase I data [2, 31, our group decided to evaluate the antitumor activity of the non-nephroand neurotoxic p...

The concentration dependence of the activity for formic acid oxidation at pH 1.2 and 4 has been studied on Pt(111) with different coverages bismuth. results clearly show: (1) FAOR bismuth-modified no relation HCOOb adsorbed platinum but depends bismuth coverage. (2) Tafel slope is ca. 90 - 110 mV in lower potential increases to nearly vertical asymptote when increases. (3) Free Pt sites are req...

BACKGROUND South Africa is the largest producer of platinum group metals in the world. Platinum is found in the Bushveld Complex in the north-east of the country. This volcanic intrusion contains many other minerals, including crystalline silica. Little is known about the health risks in the platinum mining industry. AIMS To explore the potential for platinum mine workers to develop silicosis...

Adjuvant chemotherapy using TS-1 or capecitabine plus oxaliplatin improves survival outcomes after radical gastrectomy, with both regimens showing similar efficacies.A total of 494 patients with stage II‒III gastric cancer who underwent curative D2 gastrectomy and received adjuvant chemotherapy from April 2004 to June 2014 were included in this study. 219 patients received TS-1, and 275 receive...
