[structure: see text] TMC-264 (1), a novel tricyclic heptaketide with a unique chloro-1H-dibenzo[b,d]pyran-4,6-dione skeleton, was discovered from the fungus Phoma sp. TC 1674. The structure was elucidated on the basis of NMR analyses of normal abundance and biosynthetically (13)C-enriched TMC-264. TMC-264 showed potent inhibitory activity against tyrosine phosphorylation of STAT6.
