Abstract
Two new meroterpenes, phenylpyropenes E (1) and F (2), together with seven known phenylpyropenes (3-5) and pyripyropenes (6-9) were isolated from the marine-derived fungus Penicillium concentricum ZLQ-69. Their structures including the absolute configurations were elucidated using a combination of spectroscopic methods and electronic circular dichroism calculation. Bioactivity evaluation showed that compounds 1 and 4 were cytotoxic to the MGC-803 cell line with IC50 values of 19.1 and 13.6 μM, respectively.
