Abstract
- Six new physalin steroids, 7β-methoxylisophysalin B (1), 7β-methoxylphysalin C (2), physalin V (3), physalin VI (4), physalin VII (5), isophysalin I (6), together with 20 known physalins (7-26) were isolated from calyces of Physalis alkekengi var. franchetii. Structures of the new compounds were revealed through 1D and 2D NMR and mass spectroscopic methods. Compounds 1-26 were evaluated for cytotoxicity against human HL-60, SMMC-7721, A-549, MCF-7 and SW-480, and the results indicated that compounds 8, 11, and 14 displayed potent cytotoxicities (IC505μM) in vitro. Further antibacterial assay indicated that compounds 8, 14, and 19 showed high antibacterial activities against Bacillus subtilis and Escherichia coli.
