Definition:A member of the class of 2-pyranones that is 2H-pyran-2-one substituted by a methoxy group at position 3, a hydroxy group at position 4, a methyl group at position 5 and a (2E)-3-methyl-11-phenylundec-2-en-1-yl group at position 6. Isolated from the marine sponge of the genus Plakortis, it exhibits cytotoxicity against human promyeloid leukemic HL-60 cells.
