Detection of Organophosphorus Compounds by Covalently Immobilized Organophosphorus Hydrolase
Analytical Chemistry, 2006 As 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.

Abstract About 80 OPs are thought to be in use as pesticides, primarily as insecticides (221), though they are present in thousands of formulations and applied in almost infinite working and climatic conditions to a variety of crops. Information on global production and uses of OPs for crop protection is scarce. It has been estimated

The Combinatorial Synthesis of Organophosphorus Compounds
Combinatorial Chemistry & High Throughput Screening, 2008The primary literature concerning the combinatorial synthesis of organophosphorus compounds is reviewed and discussed. The subject matter is divided into three main sections describing the solid phase, solution phase and solvent-free synthesis of phosphorus containing organic molecules.

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 ...

Lipoproteins and hydrolysis of organophosphorus compounds
Chemico-Biological Interactions, 1993Paraoxonase of human and animal sera was shown to be a structural part of high density lipoproteins (HDL) by immunoprecipitation, heparin- or polyethyleneglycol fractionation, ultracentrifugation and gel chromatography. Frequency distribution of paraoxonase activity in human sera is trimodal.

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 ...

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 ...

Further Observations on the Neurotoxicity of Organophosphorus Compounds
Journal of Occupational and Environmental Medicine, 1966Abstract Twenty-two organophosphorus compounds have been given to adult hens to test their ability to produce a delayed neurotoxic effect like that produced by triorthocresyl phosphate. Fourteen compounds falling in several structurally homologous groups were active. All of them inhibited in vitro esterases of chicken CNS.
