Curcumin Attenuates Aroclor 1254‐Induced Oxidative, Genotoxic, and Apoptotic Alterations in HepG2 Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
In HepG2 cells, Aroclor 1254 induced oxidative stress, DNA damage, apoptosis, and mutagenicity; co‐treatment with curcumin restored antioxidant defenses (GSH/thiols; SOD, CAT, GPx, GR, TrxR), reduced ROS and comet/8‐OHdG readouts, and attenuated caspase activation, demonstrating curcumin's hepatoprotective and genoprotective modulation of PCB toxicity.

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

Anaerobic Degradation of Chlorinated Hydrocarbons in Groundwater Aquifers or "Chlorinated Hydrocarbon Degradation"

, 1997
Groundwater contamination by chlorinated hydrocarbons, such as tetrachloroethene (PCE) or trichloroethene (TCE), is a major concern throughout the United States. A developing strategy for the remediation of PCE and TCE contaminated aquifers is anaerobic biodegradation.

Expanding the Toolbox for Biocatalytic Halogenation by Identification and Characterization of Three Vanadium Chloroperoxidases

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Schematic illustration of the workflow from DNA sequence‐based research to expression in shaking flasks and subsequent purification via IMAC. The obtained enzymes broaden the toolbox of enzymes used for halogenation reactions with differing catalytic properties and tolerances to reaction‐related conditions.

MnCl2‐Catalyzed Photochemical Functionalization of Unactivated C(sp3)H Bonds

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
A photochemical method enables the activation of alkanes, utilizing cheap and abundant MnCl2 as the photocatalyst. Alkenylation and alkylation reactions are performed, affording the desired products in good yields. Activation of inert C(sp3)H bonds is of great importance in organic synthesis, since it can functionalize unreactive molecules, such as ...
