Extended Data Fig. 1: Chemical structures of representative fungal RiPPs.
From: A class of benzofuranoindoline-bearing heptacyclic fungal RiPPs with anticancer activities

α-amanitin and omphalotin A from basidiomycetes (left panel) and ustiloxin B, epichloëcyclin B, victorin C, phomopsin A, and asperipin-2a from ascomycetes (right panel). The structure of epichloëcyclin B was proposed by MS/MS data. The structure of asperipin-2a was revised in 2020 by chemical synthesis72.
