摘要

Gloeostereum incarnatum is an edible mushroom that appears on broad-leaved wood in eastern Asia, northern Japan, northern China and eastern Siberia.1'2 We have focused our attention on library construction of fungal strains of mushrooms as a screening source for the biologically active small molecules useful for forward chemical genetics and development of medicinal remedy. During the course of the screening program for potential chemopreventive agents against murine B16 melanoma cells, we found potent antiproliferative activity in a culture broth of Gloeostereum incarnatum HUWCB-0029 picked in the Sapporo campus of Hokkaido University, Japan. The active compound, (—)-hirsutanol A (1), was purified with an inactive related compound, (—)-hirsutanol C (2), through bioassay-guided isolation. After derivatizing 1 to (+)-incarnal (3), we confirmed that the strain produced trace amount of 3 too.
