Abstract
AIM: To investigate the chemical constituents of the cultures of Laetiporus sulphureus (Bull.) Murrill. METHOD: Compounds were isolated and purified by various chromatographic techniques. The structure of the new compound was determined by interpretation of MS and 1D-, 2D-NMR spectroscopic data, while the known compounds were identified by comparison of their data with those reported. RESULTS: Three mycophenolic acid derivatives, 6-((2E, 6E)-3, 7-dimethyldeca-2, 6-dienyl)-7-hydroxy-5-methoxy-4-methylphtanlan-1-one (1), 6-((2E, 6E)-3, 7, 11-trimethyldedoca-2, 6, 10-trienyl)-5, 7-dihydroxy-4-methylphtanlan-1-one (2), and 6-((2E, 6E)-3, 7, 11-trimethyldedoca-2, 6, 10-trienyl)-7-hydroxy-5-methoxy-4-methylphtanlan-1-one (3) were isolated. CONCLUSION: Among them, compound 1 was new, and compound 2 exhibited moderate cytotoxicity against HL-60, SMMC-7721, A-549, and MCF-7 cells, with IC50 values of 39.1, 31.1, 27.4, and 35.7 μmol·L(-1), respectively.
