Insight into naphthoquinone metabolism: β-glucosidase-catalysed hydrolysis of hydrojuglone β-d-glucopyranoside

Autor: Christian Jay-Allemand, Gérard Kéravis, Jean-Marc Lancelin, Laurent Duroux, Francis M. Delmotte

Publikováno v: Biochemical Journal. 333:275-283

In plants, the naphthoquinone juglone is known to be involved in pathogenic defence mechanisms, but it may also take part in plant developmental processes. This naphthoquinone can accumulate in a glycosylated form, namely hydrojuglone beta-d-glucopyr

Autor: Gérard Kéravis, Nadjoua Chanegriha, Jacques R. Chrétien, Aoumeur Baaliouamer, Brahim-Y. Meklati

Publikováno v: Journal of Essential Oil Research. 9:555-559

The leaf oils of four Cypress species growing in Algeria were examined by GC and GC/MS. In total 76 constituents were identified, from which 49, 46, 48 and 54 compounds were found in the oils of Cupressus glabra Sudw., C. arizonica Greene, C. semperv

Mutagenic heterocyclic nitrogen compounds related to protein pyrolysates. V. Electron impact fragmentation of L-glutamic acid and related dipyrido[1,2-a:3′,2′-d]imidazoles

Autor: Gérard Kéravis, Bernard Loukakou, G. Saint-Ruf, Eric Hebert

Publikováno v: Journal of Heterocyclic Chemistry. 23:425-431

Six dipyrido[1,2-a:3′,2′d]imidazole derivatives related to glutamic acid pyrolysates have been studied by mass spectrometry. The data indicate that there are certain ions which are characteristic of the fragmentation of this family of compounds u

Étude par chromatographie liquide haute pression de 17-cétostéroides libres et conjugués

Autor: Gérard Kéravis, Marc Henri Durand, Michel Lafosse

Publikováno v: Journal of Chromatography A. 118:283-294

High-pressure liquid chromatography (HPLC) should be used more frequently in biomedical research because heavy molecules can be analysed at ambient temperature without derivatisation to volatile compounds. In this paper the separation of four free 17
