Two Additional New Compounds from the Marine-Derived Fungus Pseudallescheria ellipsoidea F42-3

Abstract

Two additional new compounds, pseudellone D (1) and (5S,6S)-dihydroxylasiodiplodin (3), along with the two known compounds lasiodipline F (2), (5S)-hydroxylasiodiplodin (4) were isolated from the marine-derived fungus Pseudallescheria ellipsoidea F42-3 associated with the soft coral Lobophytum crassum. Their structures, including absolute configurations, were elucidated on the basis of the corresponding spectroscopic data and electronic circular dichroism (ECD) spectra.
