Organophosphorus compounds—XV
Tetrahedron, 1972Abstract Trimethyl and triethyl phosphites react with quinoneimine IV, in aprotic and protic solvents to produce compounds V, VI and VII. The outcome of this reaction depends on the experimental conditions. Triphenyl phosphite, triphenyl-phosphine and phosphorous acid cause the quantitative reduction of IV to VII.

Mitochondrial dysfunction and organophosphorus compounds
Toxicology and Applied Pharmacology, 2013Organophosphorous (OPs) pesticides are the most widely used pesticides in the agriculture and home. However, many acute or chronic poisoning reports about OPs have been published in the recent years. Mitochondria as a site of cellular oxygen consumption and energy production can be a target for OPs poisoning as a non-cholinergic mechanism of toxicity ...

Fungicidal action of organophosphorus compounds
1969In Japan, some organomercuric compounds and an antibiotic blasticidin S have been used for many years for the control of the rice blast which is caused by the infestation of Pyricularia oryzae. Recently remarkable controlling effectiveness of some benzyl phosphoric esters on the rice blast was found by the research group of the Ihara Chemicals Co ...

[81] Organophosphorus compounds
1967Publisher Summary Many organophosphorus compounds (P-compounds) completely inactivate a number of esterases and proteases thorough studies of the reaction of these compounds with enzymes. The inhibition of an enzyme by a P-compound is accompanied by phosphorylation of a single serine hydroxyl group per catalytic center of the enzyme molecule without ...

Reactions with organophosphorus compounds—IV
Tetrahedron, 1967Abstract 1,2,3-Indantrione (II) reacts with dialkyl phosphites, yielding colourless 2:1 adducts, believed to have structure III. 2-Benzylidene-1,3-indandione (IX) reacts with diethyl phosphite, forming 1:1 adduct, having structure X. The action of triethyl phosphite on IX in benzene solution has been investigated and the resulting 1:1 adduct could ...

Detection of Organophosphorus Compounds by Covalently Immobilized Organophosphorus Hydrolase
Analytical Chemistry, 2006As a consequence of organophosphorus (OP) toxins posing a threat to human life globally, organophosphorus hydrolase (OPH) has become the enzyme of choice to detoxify such compounds. Organophosphorus hydrolase was covalently immobilized onto a quartz substrate for utilization in paraoxon detection.

Organophosphorus compounds. II. Metabolic considerations
Veterinary Research Communications, 1987Organophosphorus compounds are esters of alcohols with phosphoric acids or anhydrides of phosphoric acids with some other acids. The most important groups are the phosphates, phosphorothionates, phosphorothioates, phosphoroamidates, phosphorochloridate and phosphonates.
