NIOSH skin notation (SK) profiles :\ua0sodium fluoroacetate

open access: yes
As the largest organ of the body, the skin performs multiple critical functions, such as serving as the primary barrier to the external environment. For this reason, the skin is often exposed to potentially hazardous agents, including chemicals, which ...

Chiral fluoroacetic acid: synthesis of (R)- and (S)-[H-2(1)]-fluoroacetate in high enantiopurity

open access: yes, 2013
A two-step synthesis of (R)- and (S)-[H-2(1)]-fluoroacetate (sodium salts) in high enantioselectivity is reported. The synthesis is the development of a previous one in which the enantioselectivity has been increased from similar to 38% ee to >95% ee.

19F NMR as a Molecular Reporter: Labelling Strategies and Methods for Probing Biomolecular Motion and Exchange

open access: yesChemistry–Methods, Volume 6, Issue 2, February 2026.
This review summarizes the unique benefits 19F NMR spectroscopy has to offer for the study of biological systems. Particular focus is laid on the available strategies for incorporation of fluorinated probes into proteins and the latest applications of the ever‐expanding toolbox of fluorine NMR methodology to study structure and dynamics.

A Review of β‐Lactamase Inhibitors in Clinical Use and Development: Mechanisms, Spectrum, and Therapeutic Applications

open access: yesInternational Journal of Microbiology, Volume 2026, Issue 1, 2026.
β‐Lactam antibiotics have long served as a cornerstone for treating bacterial infections. However, their widespread and often indiscriminate use has fueled the emergence of multidrug‐resistant Gram‐negative pathogens, primarily through the production and dissemination of β‐lactamase enzymes.

Sequential Optimization Approach Toward an Azapeptide‐Based SARS‐CoV‐2 Main Protease Inhibitor

open access: yesArchiv der Pharmazie, Volume 358, Issue 12, December 2025.
A series of small‐molecule azapeptides with various cysteine‐reactive electrophilic groups was designed, synthesized, and investigated for Mpro inhibition. Particularly suitable warheads were identified, and their linkage to a structurally expanded peptidomimetic scaffold afforded the potent lead compound 12, with kinac/Ki = 78,900 M–1s–1 and an ...

Invasive Predator Management Can Mitigate the Impacts of Fire and Low Rainfall for Some Herpetofauna

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Fire, invasive predators, and drought are major threats for herpetofauna. These key global drivers are known to interact, yet, research investigating their interactive effects on wildlife remains limited. We found the management of invasive predators could partially mitigate the negative effects of prescribed fire and low rainfall for some species ...

Ion chromatographic determination of haloacetates in environmental samples

open access: yes, 2005
A method is reported for the sensitive, simultaneous determination of mono-, di-, and trifluoroacetates by ion chromatography. These species were separated using a Dionex AS17 anion-exchange column employed with a potassium hydroxide gradient (via a ...

Halide Abstraction from Halogenated Acetate Ligands by Actinyls: A Competition between Bond Breaking and Bond Making

open access: yes, 2016
Transfer of halogen atoms from halogenated acetate ligands, CX3CO2 (X = F, Cl, Br), to actinyls, AnO22+ (An = U, Np, Pu) is stimulated by collision-induced dissociation (CID) in a quadrupole ion trap. CID of [AnO2(CF3CO2)3]− complexes results exclusively

Simultaneous determination of monofluoroacetate, difluoroacetate and trifluoroacetate in environmental samples by ion chromatography

open access: yes, 2004
A method is reported for the sensitive, simultaneous determination of mono- (MFA), di- (DFA), and trifluoroacetates (TFA) by ion chromatography (IC).
