A new 2-benzopyran-1,3-dione, talaromycone A (1), was isolated from Talaromyces wortmannii LGT-4, an endophytic fungus of Tripterygium wilfordii. The structure of 1 was elucidated by IR, MS, and 1D and 2D NMR spectra and comparison of the experimental and electronic circular dichroism (ECD) data. The phosphoinositide 3-kinase (PI3Kα) inhibitory activities of 1 was also tested. The compound did not show good biological activity.
