Abstract The unfolded protein response has recently been implicated as a mechanism by which 1,10-phenanthroline-containing coordination compounds trigger cell death. We explored the interaction of two such compounds—one containing copper and one manganese—with endoplasmic reticulum (ER) stress. Pretreatment with anisomycin significantly enhanced cytotoxic activity both metal-based in A2780, but...

Manganese has attracted significant recent attention due to its abundance, low toxicity, and versatility in catalysis. In the present study, a series of manganese (III) complexes supported by salan ligands have been synthesized characterized, their activity as catalysts hydrosilylation carbonyl compounds was examined. While chloride exhibited minimal catalytic efficacy without activation silver...

1. A study of the mode of combination which takes place between certain amino acids, proteins, various carboxylic acids, and certain sulfonic acids and manganous ions to form complexes is reported. 2. Three criteria for complex formation were used: (a) the equilibrium between the substance under test and manganous ions dissolved in aqueous buffered solution and isonitrosoacetophenone dissolved ...

A series of carboxyethylphosphonate hybrid materials has been prepared: Mn(II)(O3PCH2CH2COOH) *H2O (1), Mn(III)(OH)(O3PCH2CH2COOH)*H2O (2), Al3(III)(OH)3(O3PCH2CH2CO2)2 *3H2O (3) and Cr2(III)(OH)3(O3PCH2CH2CO2) *3H2O (4). Compounds 1 and 2 were synthesized from Mn(III)(CH3COO)3 *2H2O under hydrothermal, or refluxing treatments, respectively. The crystal structures of the manganese-bearing solid...

Three new manganese oxy-bis(benzoate) compounds, synthesized by increasing the reaction temperature, with increasing dimensionality and decreasing Mn-Mn distances, indicate a possible pathway through an entropy driven dehydration route.

The solvent-free reactions of β-enamino carbonyl compounds with 1-(pyridin-2-yl)-enones in the presence of manganese(iii) acetate dihydrate unexpectedly afforded 2-acyl-3-aryl-6,7-dihydro-4(5H)-benzofuran derivatives under mechanical milling conditions.

Intravenous injection of self-produced ephedrone (metcathinone) using potassium permanganate as an oxidant can lead to severe, fixed encephalopathy. This risk applies mainly to young individuals experimenting with "home-made" drugs and results in an irreversible aggravation of overall functioning. Besides multiple neurological symptoms and movement disorders, affected individuals also experienc...
