A new asteltoxin analog with insecticidal activity from Pochonia suchlasporia TAMA 87

摘要

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 LDsub50/sub value of 0.94?μg/mg prepupal body weight.
