Selenium- and Tellurium-Based Antioxidants for Modulating Inflammation and Effects on Osteoblastic Activity

Antioxidants, 2017
Increased oxidative stress plays a significant role in the etiology of bone diseases. Heightened levels of H2O2 disrupt bone homeostasis, leading to greater bone resorption than bone formation. Organochalcogen compounds could act as free radical trapping

Diphenyl Ditelluride Intoxication Triggers Histological Changes in Liver, Kidney, and Lung of Mice

Analytical Cellular Pathology, 2015
Tellurium compounds may be cytotoxic to different cells types. Thus, this work evaluated the effect of diphenyl ditelluride ((PhTe)2), an organotellurium commonly used in organic synthesis, on the morphology of liver, kidney, and lung.

Chiral isotellurourea Lewis base catalysts [PDF]

Asymmetry
Our group has recently introduced chiral isotelluroureas as a new class of Lewis base catalysts, which show increased nucleophilicity and basicity as compared to the lighter chalcogen-based congeners within the family of isochalcogenoureas.

Chalcogen‐Guided Control of Azoarene Photoswitching: Tuning Excited‐State Energies Through Electronic Property Modulation

Chemistry – A European Journal, Volume 31, Issue 45, August 13, 2025.
Photophysical 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.
