Isolation of the terpestacin from the endophytic fungus Drechslera ravenelii
Studies about biprospection in endophytic fungi isolated from Smalanthus sonchifolius, the fermentation in solid medium rice-oat by 720 hours of the fungus Drechslera ravenelii (SS33) led to the isolation of sesterpene terpestacin. The
molecule terpestacin has attracted the scientific community attention
due to inhibitory activity in the syncytium formation caused by the HIV
virus and also by presenting unusual chemical structure. After
fermentation in the rice-oat medium, the hydroalcoholic extract was
submitted to the liquid-liquid partition with n-hexane,
dichloromethane, ethyl acetate and butanol. The dichlorometanic fraction
was subjected to chromatographic processes to obtain 19.0 mg of
terpestacin. The structure of this compound was were elucidated by
detailed spectroscopic analyses. This study reported the isolation of
terpestacin from the endophytic fungus Drechslera ravenelii for the first time.
