Ochraceopetalin (1), a mixed-biogenetic salt compound and its component 2 were isolated from the culture broths of a marine-derived fungus, Aspergillus ochraceopetaliformis. Based on combined spectroscopic and chemical analyses, the structure of 1 was determined to be a sulfonated diphenylether-aminol-amino acid ester guanidinium salt of an unprecedented structural class, while 2 was determined to be the corresponding sulfonated diphenylether. Ochraceopetaguanidine (3), the other guanidine-bearing aminol amino acid ester component, was also prepared and structurally elucidated. Compound 1 exhibited significant cytotoxicity against K562 and A549 cells.

A new dipeptide, named tolyprolinol, was isolated from the static culture of a fungus, Tolypocladium sp. FKI-7981. The structure of tolyprolinol was elucidated as N-acetyl-l-phenylalanyl-l-prolinol. It showed moderate antimalarial activity but did not show cytotoxicity or any other antimicrobial property.
