Abstrakt: A new drimane sesquiterpene ester, designated insuetusolate (1), and four reported ones (2-5) were isolated from a culture broth of Aspergillus insuetus BF-1613. The chemical structure of 1 was elucidated by extensive spectroscopic analyses, including MS and NMR. Compound 1 has a drimane-type sesquiterpene core with a 2'E,4'E,6'E-octatrienoate side chain. All these drimane sesquiterpene esters inhibited both sterol O-acyl transferase 1 (SOAT1) and 2 (SOAT2), but exhibited slightly potent inhibition against SOAT1 than SOAT2 with selectivity index (SI) [log (IC 50 for SOAT1/ IC 50 for SOAT2)] values ranging from -0.24 to -0.94.
