Cytotoxic, Genotoxic, and Mutagenic Effects of Organotellurane RF07 in Female Swiss Mice (Mus musculus). [PDF]

Chem Biodivers
ABSTRACT The organotellurane RF07 (RF07) is an organic compound containing tellurium, a rare semi‐metal, and its leishmanicidal and antimalarial activity has already been reported in previous studies. This study evaluated the toxic effects of RF07 at 0.42, 21.37, and 42.75 mg/kg using comet assay, micronucleus test, and hematological/biochemical tests ...

Synthesis, Biological Evaluation, and Molecular Docking of Tellurium-Containing Benzothiazole Derivatives as Enzyme Inhibitors of DNA Gyrase and Dihydrofolate Reductase. [PDF]

Biomed Res Int
Tellurium‐containing heterocycles represent an emerging class of organochalcogen compounds with notable redox properties and antimicrobial potential. Incorporation of tellurium into sulfur‐ and nitrogen‐containing frameworks can enhance biological activity through increased polarizability and favorable noncovalent interactions.

Unraveling the Organotellurium Chemistry Applied to the Synthesis of Gold Nanomaterials

ACS Omega, 2016
Long-term preservation of the properties of gold nanoparticles in both solution and the dry powder form can be difficult. We have overcome this challenge by using organotellurium derivatives as both reducing agents and stabilizers in the synthesis of ...

The Cellular Thioredoxin-1/Thioredoxin Reductase-1 Driven Oxidoreduction Represents a Chemotherapeutic Target for HIV-1 Entry Inhibition. [PDF]

PLoS ONE, 2016
BACKGROUND:The entry of HIV into its host cell is an interesting target for chemotherapeutic intervention in the life-cycle of the virus. During entry, reduction of disulfide bridges in the viral envelope glycoprotein gp120 by cellular oxidoreductases is

Tellurophene-Induced Triplet-Singlet Spin-Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing. [PDF]

Angew Chem Int Ed Engl
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Transition-Metal-Free Synthesis of Unsymmetrical Diaryl Tellurides via S_H2 Reaction of Aryl Radicals on Tellurium

Molecules, 2022
Although diaryl tellurides are parent organotellurium compounds, their synthesis methods, especially for unsymmetrical ones, are limited. This may be due to the instability of diaryl tellurides and their synthesis intermediates under reaction conditions.
