title: Hirsutellide A, a new antimycobacterial cyclohexadepsipeptide from the entomopathogenic fungus Hirsutella kobayasii.
abstract: A new cyclohexadepsipeptide, named hirsutellide A (1), was isolated from a cell extract of the entomopathogenic fungus Hirsutella kobayasii BCC 1660. The structure of 1 was elucidated by analyses of spectroscopic data, and its absolute stereochemistry was addressed by the use of Marfey's method. Hirsutellide A (1) exhibited antimycobacterial and antimalarial activities, but was inactive toward the Vero cell line (at 50 microg/mL).
