Since metals are cable of catalysing the free radical reactions, different metal (Mg, Mn, Zn) compounds were studied to determine their hydroxyl radical generating and/or scavenging abilities depending on ligand in a H2O2/OH -luminol system with or without microperoxidase. Magnesium oxide, magnesium gluconate and manganese gluconate increase the free radical reactions in the H2O2/OH -luminol sy...

Synthesis and reactivity of monomeric magnesium and zinc silyl compounds To(M)M-Si(SiHMe2)3 and To(M)M-Si(SiMe3)3 are described (To(M) = tris(4,4-dimethyl-2-oxazolinyl)phenylborate). The magnesium compounds react slowly with water and air, while the zinc compounds are inert. With CO2, To(M)Mg-Si(SiHMe2)3 provides To(M)MgO2CSi(SiHMe2)3 through CO2 insertion, whereas To(M)Zn-Si(SiHMe2)3 affords T...

Magnesium bromide radicals have to be prepared as high-temperature molecules and trapped as a metastable solution because a seemingly simple reduction of donor-free Grignard compounds failed. However, the essential role of magnesium(I) species during the formation of Grignard compounds could be demonstrated experimentally.

This work reports the preparation of a Tc generator based on conversion of Mo produced by neutron irradiation, into insoluble magnesium Mo-molybdates compounds as matrix. The effect of magnesium salt types and concentration, Mg:Mo molar ratios, pH of molybdate solutions, eluate volume as well as the addition order of molybdate and magnesium solutions’ influences on the final Tc were evaluated. ...

Magnesium compounds have been used in the healthcare setting for many years. Over-the-counter (OTC) products like magnesium oxides and magnesium hydroxides (magaldrate, Antiflux, Lowsium, Riopan) are used as antacids; magnesium salicylates (Doan’s pills, Magan, Mobidin) are used as non-narcotic analgesics; and magnesium salts (Milk of Magnesia) are used for constipation. This article focuses on...
