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 ...

Maleic Anhydride and Its Derivatives: A Brief Review of Reactivity and Properties in Radical (Co)Polymerizations. [PDF]

Macromol Rapid Commun
Maleic anhydride (MAnh) and its derivatives are underutilized monomer classes, each with unique reactivities and properties, which afford the synthesis of highly functional (co)polymers. This review explores the current understanding, opportunities, and limitations associated with maleic anhydride and its derivatives in conventional radical and ...

Dihalogens Binding and Activation by Imidazoline-2-Chalcogenone Model Derivatives: Insight from a Computational Approach. [PDF]

Chemistry
1,3‐dimethyl‐4‐imidazoline‐2‐chalcogenones react with dihalogens, initially forming a charge‐transfer (CT) adduct, which may evolve to the most stable T‐shaped hypercoordinate (TY) species. However, in silico results show that the CT adduct is more stable than the corresponding TY species for the sulfur and iodine combination.

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

Chalcogen-Guided Control of Azoarene Photoswitching: Tuning Excited-State Energies Through Electronic Property Modulation. [PDF]

Chemistry
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.

Long-Range Supramolecular Synthon Isomerism: Insight from a Case Study of Vinylic Tellurium Trihalides Cl(Ph)C=C(Ph)TeX₃ (X = Cl, I)

Chemistry, 2022
A slight modification of the synthetic procedure resulted in a new (Cc) polymorph of vinylic tellurium-trichloride Z-Cl(Ph)C=C(Ph)TeCl3 (1, β-form) which is stabilized by Te⋯Cl chalcogen bonds, assembling its molecules into the zigzag chains.
