Differential genotoxicity of diphenyl diselenide (PhSe)2 and diphenyl ditelluride (PhTe)2 [PDF]
PeerJ, 2014 Organoselenium compounds have been pointed out as therapeutic agents. In contrast, the potential therapeutic aspects of tellurides have not yet been demonstrated.

Chalcogen-Guided Control of Azoarene Photoswitching: Tuning Excited-State Energies Through Electronic Property Modulation. [PDF]
ChemistryPhotophysical properties of ortho‐tellurium‐substituted azoarenes are tunable via aryl substituent electronics and tellurium oxidation state. Electron‐donating groups destabilize the excited state three‐electron σ bond, enhancing photoisomerization.

A glimpse on biological activities of tellurium compounds
Anais da Academia Brasileira de Ciências, 2009 Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic ...

Stabilization of 2-Pyridyltellurium(II) Derivatives by Oxidorhenium(V) Complexes
Chemistry, 2023 Zwitterionic compounds such as pyridine-containing tellurenyl compounds are interesting building blocks for heterometallic assemblies. They can act as ambiphilic donor/acceptors as is shown by the products of reactions of the zwitterions HpyTeCl2 or ...

In vitro and in vivo activity of an organic tellurium compound on Leishmania (Leishmania) chagasi. [PDF]
PLoS ONE, 2012 Tellurium compounds have shown several biological properties and recently the leishmanicidal effect of one organotellurane was demonstrated. These findings led us to test the effect of the organotellurium compound RF07 on Leishmania (Leishmania) chagasi,
