stachybotrys toxins. 1

Cultures of several isolates of Stachybotrys chartarum have produced a series of cytotoxic macrocyclic trichothecenes including two newly characterized conseners: isosatratoxin G and S-isosatratoxin H. Nine immunosuppressant phenylspirodrimanes (1–9) were isolated and characterized, the majority of which are newly reported compounds. © 1995 Wiley-Liss, Inc.
