Intrinsic Specific Activity Enhancement for Bifunctional Electrocatalytic Activity toward Oxygen and Hydrogen Evolution Reactions via Structural Modification of Nickel Organophosphonates.

Inorganic Chemistry
A comprehensive knowledge of the structure-activity relationship of the framework material is decisive to develop efficient multifunctional electrocatalysts.

Utilisation of structurally diverse organophosphonates by Streptomycetes

Applied Microbiology and Biotechnology, 2003
A group of streptomycete strains was found able to utilise a wide range of structurally diverse phosphonates as a sole phosphorus source. No relation could be observed between ability to synthesise compounds containing a direct carbon-to-phosphorus (C-P) bond and biodegradative potential towards phosphonates in the strains studied.

Isomeric Benzenediol-Linked Organophosphonates as a Handy Reusable Emitting Platform: Diversity in Polyamine Vapor Detection.

Journal of Organic Chemistry
This work introduces metal/column-free facile quantitative access to conformationally twisted catechol-linked organophosphonate (CAP) as a blue-emitting solid that could reversibly detect only 1,3-diaminopropane (DAP) and 1,2-ethylenediamine (EDA) vapors,

Analysis of the herbicide glyphosate and related organophosphonates in seawater : overcoming salt-matrix-induced limitations

, 2020
Methods for the detection of polar organophosphonates like the herbicide glyphosate and its metabolite aminomethylphosphonic acid (AMPA) in seawater were developed within this thesis.

Bis(difluoroaluminum)organophosphonates and difluoroaluminumdiorganophosphinates

Journal of Polymer Science: Polymer Chemistry Edition, 1984
AbstractOligomers and polymers of the general types [RR′P(O)OA1F2]n, I, and [F2AlOP(R)(O)OAlF2]n, II, were prepared by the addition of phosphonic or phosphinic acids and hydrogen fluoride to etherated alanes. The hydrocarbon moieties (R,R′) on the phosphonic and phosphinic acids were important determinants of physical and chemical properties.

Catabolism of organophosphonates: biochemistry, physiology and interactions of degrading bacteria in the environment

, 2020
The major contribution of microorganisms in metabolism of natural and synthetic phosphonates, the biochemical bases of these processes and possible interactions between degrading bacteria in natural and anthropogenic ecosystems are presented in the light

Radical-based dephosphorylation and organophosphonate biodegradation

Journal of the American Chemical Society, 1987
Products resulting from the degradation of organophosphonates by Escherichia coli are identified and used as a basis for evaluating mechanisms which may be the chemical basis of the biodegradation. One mechanistic hypothesis which is consistent with the biodegradation products involves radical-based dephosphorylation.

Organophosphonic acids as drug candidates

Expert Opinion on Therapeutic Patents, 2006
The discovery of phosphate mimetics that are suitable as drug candidates has been a challenging problem faced by medicinal chemists for many years. Several series of organophosphonic acids have been identified as phosphate mimetics and have resulted in multiple development candidates progressing to the clinic and even successfully reaching the market ...

(24) Acetylcholinesterase mutants—oxime-assisted catalytic scavengers of organophosphonates

Chemico-Biological Interactions, 2005
instead abstract, part of the Introduction: Reaction of organophosphonates with acetylcholinesterase (AChE ; EC 3.1.1.7) is characterized by the formation of serine-conjugated adducts that are only slowly reversible. Since oximes are the only known antidote to nerve agent poisoning that restore the activity of AChE, mutagenesis of AChE should enable ...
