A rapid primary screening method for antitumor using the oomycete Pythium aphanidermatum. Repositório Alice
SANTOS, S. N.; MELO, I. S. de.
Investigating bioactive components from microbial metabolites can provide potential source for drug discovery. There are a number of traditional antitumor compounds screening assays already described. In this study, we have developed an efficient method to search for antitumor compounds using the Oomycete Pythium aphanidermatum as model on agar plates for high throughtput screening. Antioomycete compounds showed cytotoxic effects in human cancer cells lines due to the possible similarity between the lipid cell membrane of the Pythium species and cancerous cells, suggesting the compounds act through similar mechanisms of inhibition. In this assay, i t is possible to evaluate hundreds of samples, with results in few hours. The Pythium assay was shown to be...

Paiva,Selma R.; Lima,Lucilene A.; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
Plumbago scandens L. is a Brazilian tropical/subtropical species that occurs along the coast. Chemically it is mainly represented by naphthoquinones, flavonoids, terpenoids and steroids. The aim of the present work is to study quantitative changes in the root metabolic production of Plumbago scandens during different physiologic developmental stages relative to floration. The results indicated the presence of four substances in the extracts: plumbagin, epi-isoshinanolone, palmitic acid and sitosterol, independent on developmental stage. The naphthoquinone plumbagin has always showed to be the major component of all extracts. Naphthoquinones exhibited their highest content during floration, while the content of the two others components decreased during...

Daphnia magna Exudates Impact Physiological and Metabolic Changes in Microcystis aeruginosa ArchiMer
Bojadzija Savic, Gorenka; Edwards, Christine; Briand, Enora; Lawton, Linda; Wiegand, Claudia; Bormans, Myriam.
While the intracellular function of many toxic and bioactive cyanobacterial metabolites is not yet known, microcystins have been suggested to have a protective role in the cyanobacterial metabolism, giving advantage to toxic over nontoxic strains under stress conditions. The zooplankton grazer Daphnia reduce cyanobacterial dominance until a certain density, which may be supported by Daphnia exudates, affecting the cyanobacterial physiological state and metabolites’ production. Therefore, we hypothesized that D. magna spent medium will impact the production of cyanobacterial bioactive metabolites and affect cyanobacterial photosynthetic activity in the nontoxic, but not the toxic strain. Microcystin (MC-LR and des-MC-LR) producing M. aeruginosa PCC7806 and...
