<i>stachybotrys</i> toxins. 1

Abstract

Cultures of several isolates of Stachybotrys chartarum have produced a series of cytotoxic macrocyclic trichothecenes including two newly characterized congeners: isosatratoxin G and S-isosatratoxin H. Nine immunosuppressant phenylspirodrimanes (1-9) were isolated and characterized, the majority of which are newly reported compounds.
