Scytophycins

摘要

Scytophycins A, B, C, D and E, an aldehyde and alcohol derivative of scytophycin B and the specified alkanoyl and benzoyl esters of scytophycins A, B, C, D and E and the B derivatives (scytophycin compounds) are novel antineoplastic and antifungal agents. Antifungal compositions containing a scytophycin compound and methods of inhibiting fungi, especially plant pathogenic fungi, using these compositions are included. A method for producing the scytophycin complex, comprising scytophycins A, B, C, D and E, using a new strain of the blue-green alga Scytonema pseudohofmanni, and a biologically purified culture of the alga are also provided.
