Abstract

A new inhibitor of TNF-α production (IC50=0.89 μM) named vialinin C (1) was isolated from dry fruiting bodies of an edible Chinese mushroom, Thelephora vialis. The structure of 1 was determined by high-resolution MS, NMR spectroscopic analysis, and confirmed by synthesis. Synthesis of ganbajunin B (5) obtained from the same origin was also described.
