The new spirocyclic diketopiperazine alkaloid spirotryprostatin F was isolated from the marine isolate of the fungus Aspergillus fumigatus. The structure of the compound was established using on NMR spectroscopy, high-resolution mass spectrometry, and acid hydrolysis. Spirotryprostatin F in low and ultralow doses (10–6–10–17 M) exhibited stimulating action on the growth of sprout roots of soy [Glycine max (L.) Merr.], buckwheat (Fagopyrum esculentum Moench), and corn (Zea mays L.). The dose-effect curve had a bimodal character.
