Description générale

2,5-Dichlorohydroquinone (2,5-DCHQ) is a hydroquinone derivative that can be synthesized by reducing 2,5-dichloroquinone using sodium dithionite (Na2S2O4). The kinetics of the reaction of 2,5-DCHQ and N-phenyl-1,4-benzoquinonemonoimine has been studied. The transformation of 2,5-DCHQ to 2-chloromaleylacetate using PcpA (Pcp = pentachlorophenol) protein, isolated from Escherichia coli has been investigated. It is reported to be the degradation product of 2,4,5-trichlorophenoxyacetic acid and γ-hexachlorocyclohexane.

p-Dichlorobenzene (p-DCB) has been reported to be carcinogenic for rodents, although it does not seem to be mutagenic in bacterial test systems. In this study, the mechanism of DNA damage by metabolites of p-DCB in the presence of metals was

In Pseudomonas paucimobilis UT26, gamma-hexachlorocyclohexane (gamma-HCH) is converted to 2,5-dichloro-2,5-cyclohexadiene-1,4-diol (2,5-DDOL), which is then metabolized to 2,5-dichlorohydroquinone. Here, we isolated from the genomic library of UT26 two genes which expressed 2,5-DDOL dehydrogenase activity when they were transformed into P. putida

Combined cell suspensions of the 2,4,5-trichlorophenoxyacetic acid (2,4,5-T)-metabolizing organism Pseudomonas cepacia AC1100, and the 2,4-dichlorophenoxyacetic acid (2,4-D)-metabolizing organism Alcaligenes eutrophus JMP134 were shown to effectively degrade either of these compounds provided as single substrates. These combined cell suspensions, however, poorly

Two total syntheses of the unsymmetrical bis-indolylquinone natural product demethylasterriquinone B1 (also known as L-783,281) have been accomplished. The first exploits a known base-promoted condensation of indoles with bromanil, which stops at monoaddition using the sterically hindered 2-isoprenylindole. This permits
