Organoselenium Compounds as Phytochemicals from the Natural Kingdom [PDF]

Natural Product Communications, 2015
Selenium is naturally present in soils but it is also produced by pollution from human activities into the environment. Its incorporation into plants affords organoselenium metabolites that, depending on the nature of the molecules and the plant species,

Toxicology and pharmacology of synthetic organoselenium compounds: an update. [PDF]

Arch Toxicol, 2021
Here, we addressed the pharmacology and toxicology of synthetic organoselenium compounds and some naturally occurring organoselenium amino acids. The use of selenium as a tool in organic synthesis and as a pharmacological agent goes back to the middle of the nineteenth and the beginning of the twentieth centuries.
