Popis: | Two new tetranorlabdane diterpenoids, named botryosphaerins G (1) and H (2), were isolated from the solid fermentation products of Botryosphaeria sp. P483 along with seven known tetranorlabdane diterpenes (3–9). Their structures were elucidated by extensive analysis, including 1D and 2D nuclear magnetic resonance (NMR) spectroscopy, and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS). Their absolute configuration was confirmed by single-crystal X-ray diffraction analyses using the anomalous scattering of Cu Kα radiation. All of the isolated compounds were tested for activity against phytopathogenic fungi and nematodes. Compounds 2 and 3 showed antifungal activity and compound 2 showed weak nematicidal activity. |
