Abstract: The title compound, C₃₀H₂₈N₆O₆S₄·CHCl₃, is a cytotoxic and antibacterial compound which was isolated from ethyl acetate extracts of Amanita flavorubescens Alk. affected by Verticillium sp. The molecule is a dimer with two epidithio-dioxopiperazine nuclei, the two halves being related by an approximate twofold axis. The two five-membered rings are cis-fused. The crystal structure is stablized by a hydrogen-bond network involving both OH groups and the carbonyl group.
