A new tremulane sesquiterpene lactone, named irlactin K (1), was isolated from the culture broth of the basidiomycete Irpex lacteus. The structure of the new compound was established through extensive spectroscopic analyses. The compound was tested for its cytotoxicity against five human cancer cell lines and for its inhibitory activity against isozymes of 11β-hydroxysteroid dehydrogenases.
