A new asteltoxin analog, named asteltoxin H (1), was isolated by the solid-state fermentation of the fungus Pochonia suchlasporia var. suchlasporia TAMA 87. The chemical structure of 1 was deduced by spectroscopic methods, including 1D and 2D NMR, HRESIMS, and UV-Vis analyses. Compound 1 showed insecticidal activity against prepupae of the blowfly, Lucilia sericata, with an LD50 value of 0.94 µg/mg prepupal body weight.
