The “green” electrochemical synthesis of periodate
2020
Abstract High‐grade periodate is relatively expensive, but is required for many sensitive applications such as the synthesis of active pharmaceutical ingredients. These high costs originate from using lead dioxide anodes in contemporary electrochemical methods and from expensive starting materials. A direct and cost‐efficient electrochemical synthesis of periodate from iodide, which is less costly and relies on a readily available starting material, is reported. The oxidation is conducted at boron‐doped diamond anodes, which are durable, metal‐free, and nontoxic. The avoidance of lead dioxide ultimately lowers the cost of purification and quality assurance. The electrolytic process was opti…
Selenium: A Cure for Autoimmune Thyroiditis.
2021
Autoimmune thyroiditis (AT) is a disease whose incidence has increased dramatically over the past few decades. In iodine sufficient areas, this pathological condition affects up to 5% of the general population. The higher incidence of AT observed in areas of the world with low-selenium (Se) soils apperas to be the consequence of a reduced activity of the intracellular Sedependent glutathione peroxidase activity. Se is involved, through selenoproteins, in the regulation of intracellular antioxidant, redox and anti-inflammatory processes. As a component of selenoproteins, Se exerts various structural and enzymatic functions. A low Se/high fat diet can cause selenoprotein changes and promote t…
Active caspase-3 detection to evaluate apoptosis induced by Verbena officinalis essential oil and citral in chronic lymphocytic leukaemia cells
2011
Verbena officinalis L., Verbenaceae, commonly known as vervain, is a plant widely used in medicine. Despite of its widespread use in different traditional practices, the mechanisms of pharmacological actions of the plant and its volatile oil are still unclear. We evaluated the pro-apoptotic activity of V. officinalis essential oil and of its main component, citral, on lymphocytes collected from ten patients with chronic lymphocytic leukaemia (CLL), a disease in which a faulty apoptotic mechanism is still retained one of the primary pathogenic events, by adding to treated mononuclear cells, annexin-V, propidium iodide, and CD19. Apoptosis was also evaluated using anti-active-caspase-3 monocl…

Reaction of LiArMe6 (ArMe6= C6H3-2,6-(C6H2-2,4,6-Me3)2) with indium(I)chloride yields three m-terphenyl stabilized mixed-valent organoindium subhalid…
2016
Abstract Indium(I)chloride reacts with LiAr Me 6 ( Ar Me 6 = C6H3-2,6-(C6H2-2,4,6-Me3)2) in THF to give three new mixed-valent organoindium subhalides. While the 1:1 reaction of InCl with LiAr Me 6 yields the known metal-rich cluster In8( Ar Me 6 )4 (1), the use of freshly prepared LiAr Me 6 led to incorporation of iodide, derived from the synthesis of LiAr Me 6 , into the structures, to afford In4( Ar Me 6 )4I2 (2) along with minor amounts of In3( Ar Me 6 )3I2 (3). When the same reaction was performed in 4:3 stoichiometry, the mixed-halide compound In3( Ar Me 6 )3ClI (4) was obtained. Further increasing the chloride:aryl ligand ratio resulted in the formation of the known mixed-halide spe…
Ion pair complexes and anion binding in the solution of a ditopic receptor.
2016
The synthesis and crystal structures with alkali halides of a ditopic benzo-15-crown-5 bis-urea receptor have been presented. In addition, the anion binding properties of and its alkali metal complexes in solution are presented. A comprehensive single-crystal X-ray crystallographic study of , all together 13 crystal structures, including the ion pair complexes with NaCl, NaBr, NaI, KF, KCl, KBr, KI, RbF, RbCl, and RbI, give a detailed view of how behaves in the solid-state with different alkali halides depending on the size of the cation and anion. In the solid-state forms a 1 : 1 complex with a sodium cation and the anion is complexed as a contact (NaCl) or a separate ion pair (NaBr, NaI).…
On Demand One-Pot Mild Preparation of Layered Double Hydroxides and Their Hybrid Forms: Advances through the Epoxide Route.
2019
Epoxide ring opening driven alkalinization process was explored with the aim of preparing layered double hydroxide (LDH) phases on demand, at room temperature. Employing iodide as nucleophilic agent, the precipitation reaction can be driven under much lower halide concentrations. This scenario favors the selective intercalation of concomitant bulky oxo anions as nitrate or perchlorate in the LDH products, allowing for the one-pot synthesis of an LDH able to delaminate in formamide. Even large dicarboxylic acids, - O2 C-(CH2 )n -CO2 - , with n up to 8, can be quantitively intercalated within the growing LDH phase, providing a versatile one-pot route for hybrid LDHs as well. Under the mild co…
