Abstract:
Phytochemical investigation for a chloroform-soluble extract of dried Morus alba fruits, selected by proprotein convertase subtilisin-kexin type 9 (PCSK9) mRNA expression monitoring assay in HepG2 cells, led to the isolation of a new benzofuran, isomoracin D (1), and a naturally occurring compound, N-(N-benzoyl-l-phenylalanyl)-l-phenylalanol (2), along with 13 known compounds (3–15). All of the structures were established by NMR spectroscopic data as well as MS analysis. Of the isolates, moracin C (7) was found to inhibit PCSK9 mRNA expression with an IC50 value of 16.8 μM in the HepG2 cells.
