The Synthesis and Evaluation of Diethyl Benzylphosphonates as Potential Antimicrobial Agents [PDF]

open access: yesMolecules, 2022
The impact of substituent at phenyl ring of diethyl benzylphosphonate derivatives on cytotoxic activity was studied. The organophosphonates were obtained based on developed palladium-catalyzed α, β-homodiarylation of vinyl esters protocol.

Titanium dioxide photocatalytic degradation of organophosphonates [PDF]

open access: yes, 2020
The titanium dioxide mediated photocatalytic degradation of dimethyl phenylphosphonate (DMPP) has been investigated. DMPP can be completely decomposed by irradiation of an aqueous suspension of Ti02 in the presence of oxygen, though the total mineralization of organophosphonates takes longer than the complete decomposition of dimethyl phenylphosphonate.

Organophosphorus flame retardants in children’s car seats: Implications for vehicle air quality [PDF]

open access: yesE3S Web of Conferences, 2023
Flame retardants (FRs) are used in many consumer products for fire safety reasons. Their use in children’s car seats may result in children’s and vehicle occupants’ exposure to these compounds including inhalation exposure through poor vehicle air ...

Reversible Diels–Alder Reactions with a Fluorescent Dye on the Surface of Magnetite Nanoparticles

open access: yesMolecules, 2021
Diels–Alder reactions on the surface of nanoparticles allow a thermoreversible functionalization of the nanosized building blocks. We report the synthesis of well-defined magnetite nanoparticles by thermal decomposition reaction and their ...

Synergistic effect of NiII and Co/FeIII in doped mixed-valence phosphonate for enhancing electrocatalytic oxygen evolution

open access: yesGreen Energy & Environment, 2022
Metal organophosphonates have been explored in energy-related fields due to their high chemical and thermal stability as a type of uniformly precursor, but only few of pristine metal organophosphonate are directly used for oxygen evolution reaction (OER)

A Novel Polyphosphate-Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii. [PDF]

open access: yesEnviron Microbiol
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Structure of HI-6*sarin-acetylcholinesterase determined by X-ray crystallography and molecular dynamics simulation: reactivator mechanism and design. [PDF]

open access: yesPLoS ONE, 2009
Organophosphonates such as isopropyl metylphosphonofluoridate (sarin) are extremely toxic as they phosphonylate the catalytic serine residue of acetylcholinesterase (AChE), an enzyme essential to humans and other species.

Highly Mesoporous Zr-Based MOF-Fabric Composites: A Benign Approach for Expeditious Degradation of Chemical Warfare Agents and Simulants. [PDF]

open access: yesSmall
This research unveils a breakthrough in organophosphonate degradation using environmentally friendly mesoporous UiO–66–NH2‐fabric composites. This innovative approach, facilitated by CAPB surfactant, overcomes mass transfer limitations, creating robust, highly porous materials compatible with fragile fabrics.

Catabolism and detoxification of 1-aminoalkylphosphonic acids: N-acetylation by the phnO gene product. [PDF]

open access: yesPLoS ONE, 2012
In Escherichia coli uptake and catabolism of organophosphonates are governed by the phnCDEFGHIJKLMNOP operon. The phnO cistron is shown to encode aminoalkylphosphonate N-acetyltransferase, which utilizes acetylcoenzyme A as acetyl donor and ...
