Chelate stabilization of a titanium(IV)-salan alkoxide by ligand exchange with 2,6-pyridinedicarboxylic acid (dipic) resulted in heptacoordinate complex 3 which is not redox-active, stable on silica gel and has increased aqueous stability. 3 is highly toxic in HeLa S3 and Hep G2 and has enhanced antitumor efficacy in a mouse cervical-cancer model.

This study reports the thermodynamics of bound species derived from ethene, propene, n-butene, and isobutene on solid acids with diverse strength and confining voids. Density functional theory (DFT) and kinetic data indicate that covalently bound alkoxides form C-C bonds in the kinetically relevant step for dimerization turnovers on protons within TON (0.57 nm) and MOR (0.67 nm) zeolitic channe...

Biaryl coupling (often labelled 'C-H activation') of aromatic systems can be achieved by potassium tert-butoxide alone in the absence of any amine or bipyridine catalyst (1,10-phenanthroline or N,N'-dimethylethylenediamine being the most common), previously reported to be essential. Various mechanistic studies and observations are presented which suggest that when 1,10-phenanthroline is employe...

In current paper we demonstrate the applicability of high viscous oligomeric alkoxide concentrates in fabrication of technologically interesting structures like nanometer diameter fibers (down to 200 nm), nanoneedles (tip radii 15-25 nm) and some micrometers wide linear surface structures. The approach is cost-effective and simple as it utilizes low-cost precursor materials (metal alkoxides) co...

background: hypomagnesaemia is one of the main side effects of cisplatin-based chemotherapy regimens in cancer patients. the aim of the current investigation was to evaluate the effect of oral magnesium oxide (mgo) supplementation on cisplatin-induced hypomagnesemia. methods: this parallel-randomized controlled, open label trial was conducted in a hospital of iran university of medical sciences...

objectives: this study was designed to assess nutritional and biochemical factor of magnesium in postmenopausal osteoporotic women. methods & materials: the population of this analytical cross- sectional study, was 60 postmenopausal osteoporotic women ,referred to rheumateology clinic of tabriz. nutritional intake was determined by 3 day food recall and food frequency questionnaire، individual ...

This study compared magnesium oxide and magnesium citrate with respect to in vitro solubility and in vivo gastrointestinal absorbability. The solubility of 25 mmol magnesium citrate and magnesium oxide was examined in vitro in solutions containing varying amounts of hydrochloric acid (0-24.2 mEq) in 300 ml distilled water intended to mimic achlorhydric to peak acid secretory states. Magnesium o...
