摘要: Three new indole-containing diketopiperazine alkaloids, named variecolorins M–O (1–3), together with the eight known analogues 4–11, were isolated from a deep-ocean sediment-derived fungus, Penicillium griseofulvum. Their structures determined by analysis of spectroscopic data. The 2,2-diphenyl-1-picrylhydrazinyl (DPPH) radical-scavenging activities and cell-proliferation inhibitory three compounds 1–3 investigated.
