Mechanism of action of novel naphthofuranquinones on rat liver microsomal peroxidation.

6 Sep 2009 In order to elucidate the effect on mammal systems of new derivatives from 2-hydroxy-3-allyl-naphthoquinone, alpha-iodinated naphthofuranquinone (NPPN-3223), beta-iodinated naphthofuranquinone (NPPN-3222) and beta-methyl naphthofuranquinone ... Read more...

RP-HPLC analysis of rhinacanthins in Rhinacanthus nasutus: validation and application for the preparation of rhinacanthin high-yielding extract.

30 Aug 2009 A reversed-phase high-performance liquid chromatographic method is described for the simultaneous determination of rhinacanthin-C, rhinacanthin-D, and rhinacanthin-N in Rhinacanthus nasutus leaves. The method involved the use of a TSK-gel ODS-80Ts ... Read more...

The PqrR transcriptional repressor of Pseudomonas aeruginosa transduces redox signals via an iron-containing prosthetic group.

26 Aug 2009 Inducible defenses against oxidative stress are coordinated by redox-sensitive transcription factors that transduce oxidative damage into differential gene expression. The opportunistic human pathogen Pseudomonas aeruginosa has evolved under ... Read more...
