Two fungi, and were cultured under different conditions to obtain fourteen compounds. The axenic cultures of and in potato dextrose broth (PDB) medium yielded fusaric acid (), 9,10-dehydrofusaric acid (), and tyrosol, whereas their co-cultivation produced fusarinol (), a fusaric acid complex with magnesium (), 9,10-dehydrofusaric acid complex with magnesium (), and 5-butyl-5-(hydroxymethyl) dihydrofuranone (). Upon changing the medium from PDB to Czapek, different compounds (uracil, -hydroxy acetophenone, and cyclo(L-Leu-L-Pro) were obtained. Fusaric acid () was biotransformed into fusarinol () by , suggesting a detoxification process, and three other compounds were obtained: 7-hydroxyfusarinol (), 9,10-dehydrofusarinol (), and fusarinyl acetate (). Epigenetic modulation of suberohydroxamic acid against afforded gibepyrone B (). These compounds were subjected to a papain inhibition enzymatic assay; the highest inhibitory activity was displayed by the two magnesium complexes, at 56 and 54% inhibition, respectively.

Aims: This study aimed to assess the mode of action of fusaric and 9,10-dehydrofusaric acids on cell respiration by measuring the hyphal oxygen consumption rate, and the effects on cell membrane integrity by determining the electrical conductivity of the mycelium.
Methods And Results: Bioactivity-directed fractionation of the active culture medium and mycelium organic extracts from the Fusarium lactis strain SME13-2 isolated from Sapium macrocarpum, led to the isolation of two known alkylpicolinic acid derivatives: fusaric acid and 9,10-dehydrofusaric acid, along with the known polyketide bikaverin. Fusaric acid and 9,10-dehydrofusaric acid exhibited antioomycete and antifungal activities, significantly inhibiting the radial growth of Phytophthora capsici, Pythium aphanidermatum, Alternaria alternata and Fusarium oxysporum.
