Characterization of TJS119 and its biocontrol potential against insect pathogens.

Introduction: The white-spotted flower chafer (), which is widely distributed in Asian countries, is traditionally used in oriental medicine. However, its larvae are prone to severe damage by green muscardine disease (caused by ) during breeding. The aim of this study was to characterize TJS119, which has been isolated from freshwater, and investigate its potential as a biocontrol agent against in insects.

Large-Scale Screening of the Plant Extracts for Antifungal Activity against the Plant Pathogenic Fungi.

Plants produce chemicals of immense diversity that provide great opportunities for development of new antifungal compounds. In search for environment-friendly alternatives to the fungicide of current use, we screened plant extracts obtained from more than eight hundred plant materials collected in Korea for their antifungal activity against the model plant pathogenic fungus, Magnaporthe oryzae. This initial screening identified antifungal activities from the eleven plant extract samples, among which nine showed reproducibility in the follow-up screening.

Ovataline: A Polyketide Isolated from the Benthic Dinoflagellate cf. with 5α-Reductase Inhibitory Activity in RWPE-1 Prostatic Cells.

Ovataline (), which is a polar metabolite containing a hexahydroquinoline moiety, was isolated from cultures of the marine dinoflagellate cf. . was characterized as a zwitterionic compound with hexahydroquinoline and tetrahydropyran rings.
