The metabolism of cyano-oxime fungicide 1-(2-cyano-2-methoxyiminoacetyl)-3-ethylurea (cymoxanil) and analogs was studied on several strains of the fungus Botrytis cinerea owing to their difference in sensitivity towards cymoxanil. Chromatographic ana

The enzymatic effect of locust tissues upon hydrolysis of the fluorinated Δ 2 -oxazoline-1,3 Ia was elucidated using 19 F[ 1 H] NMR monitoring. In a phosphate buffer at pH=7.4 (mean physiological pH of locust tissues), the substrate Ia hydrolyses sl

To determine the reversible masking potential of carboxylic acids afforded by the N-acylaziridine structure, the hydrolysis of the fluorinated compound I was studied in buffered solutions at different pH, in insect tissues during invitro and exvivo a

To study the behavior of the toxins E and A destruxin in biological media, a method was developed with direct injection on to a liquid chromatographic (LC) column. Either slightly lipophilic C 1 and C 4 “wide-pore” packings or the column-switchin

International audience; Treatment of 4,6-dinitrobenzofuroxan (DNBF) with the imidazoline 1-NRf is found to afford a zwitterionic nitrogen-bonded complex (2-NRf±) which, in the presence of base (Et3N), undergoes a slow but quantitative transformation
