Abstract
l-β-(6-Azulenyl)alanine was synthesised for the first time. Supplementation of this compound to Pyricularia grisea ΔpyiA led to the biosynthesis of the unnatural (6-azuleno)chalasin H and its 1′-bromo congener that have unprecedented natural product skeletons and that are both fluorescent and highly cytotoxic, with IC50 of 0.18 μg mL−1vs. L929 cells in vitro. Actin staining showed that both compounds are potent, but partially reversible, actin disruptors.
