| Research Abstract |
From Japanese marine invertebrates, following novel compounds have been isolates as a result of bioassay-guided fractionation monitoring antifungal activity.
1. New mycalolides
From Mycale sp. collected in the Gulf of Gokasho, three novel mycalolides have been isolated as antifungal constituents. They were assigned as 30-hydroxymycalolide A, 32-hydromycalolide A, and 38-hydroxymycaloude B on the basis of spectral data.
2. Acanthosterol sulfates
From Acanthodendrilla sp. collected in the Gulf of Gokasho 10 highly hydroxylated sterol sulfates have been isolated. Their structures were determined by interpretation of spectral data.
3. Rubrosides and aurantosides
Eleven compounds that have a tetramic acid and a conjugated polyene chromophore, termed rubrosides and aurantosides, have been isolated from the Siliquariaspongeia japnica collected off Hachijo Island. Their structures were assigned on the basis of spectral data and chemical degradation.
