In vitro metabolism of the new insecticide flupyrazofos by rat liver microsomes

, p. 423 - 429 (1997)
1. The in vitro metabolism of the new insecticide flupyrazofos was studied using rat liver microsomes. Two metabolites were produced and identified as O,O-diethyl O-(1-phenyl-3-trifluoromethyl-5-pyrazoyl) phosphoric acid ester (flupyrazofos oxon) and 1-phenyl-3-trifluoromethyl-5-hydroxypyrazole (PTMHP) based on UV and mass spectral analysis. 2. Cytochrome P450 oxidatively converted flupyrazofos to flupyrazofos oxon, a major metabolite and phenobarbital-induced microsomes increased this desulphuration by 8-fold. 3. Flupyrazofos oxon was converted to PTMHP with a half-life of 47.8 min by chemical hydrolysis and this conversion also proceeded non-enzymatically under our microsomal incubation conditions.

[Figure not available: see fulltext.] We propose different methods for the synthesis of 4-hydroxyimino-5-polyfluoroalkylpyrazol-3-ones. The simplest and most convenient procedure relies on sequential one-pot treatment of polyfluoroalkyl-3-oxoesters with hydrazine and sodium nitrite in acetic acid. It was established that 4-hydroxyimino-5-polyfluoroalkylpyrazol-3-ones exist in solid state and in solutions as mixtures of Z,Е-isomers of the hydroxyimine tautomer. The synthesized compounds were characterized with respect to in vivo analgesic activity and acute toxicity.

Lipooligosaccharide (LOS) structures in the outer core of Gram-negative mucosal pathogens such as Neisseria meningitidis and Haemophilus influenzae contain characteristic glycoepitopes that contribute significantly to bacterial virulence. An important example is the digalactoside epitope generated by the retaining α-1,4-galactosyltransferase LgtC. These digalactosides camouflage the pathogen from the host immune system and increase its serum resistance. Small molecular inhibitors of LgtC are therefore sought after as chemical tools to study bacterial virulence, and as potential candidates for anti-virulence drug discovery. We have recently discovered a new class of non-substrate-like inhibitors of LgtC. The new inhibitors act via a covalent mode of action, targeting a non-catalytic cysteine residue in the LgtC active site. Here, we describe, for the first time, structure-activity relationships for this new class of glycosyltransferase inhibitors. We have carried out a detailed analysis of the inhibition kinetics to establish the relative contribution of the non-covalent binding and the covalent inactivation steps for overall inhibitory activity. Selected inhibitors were also evaluated against a serum-resistant strain of Haemophilus influenzae, but did not enhance the killing effect of human serum.

The approaches for regiocontrolled N-, O- and C-methylation of 1-phenyl-3-polyfluoroalkyl-1H-pyrazol-5-ols have been developed. The chemoselective N-methylation proved to be an efficient method for the synthesis of polyfluorinated antipyrine analogs. In addition, we reinvestigated the structure of 3-polyfluoroalkyl-1-phenylpyrazol-5-ols by the X-Ray analysis. The quantum-chemical calculations were used for an explanation of methylation processes. The preliminary biological testing revealed a significant analgesic activity of trifluoromethyl-containing antipyrine.
