title: Bisindole alkaloids from myxomycetes Arcyria denudata and Arcyria obvelata.
abstract: A new bisindole sulfate (1) and arcyroxocin B (2) were isolated from wild fruiting bodies of Arcyria denudate, along with three known bisindoles (4-6). Dihydroarcyriacyanin A (3) was obtained from wild fruiting bodies of Arcyria obvelata, along with a known bisindole (7). The structures of these compounds were elucidated on the basis of spectroscopic data, and this is the first report of full characterizations of arcyroxocin B (2) and dihydroarcyriacyanin A (3). Compounds 2, 3, and 6 showed cytotoxicity against Jurkat cells.
