The synthesis of the marinealkaloid sebastianine A and of a regioisomer has been accomplished via hetero-Diels–Alder reaction of indole-4,7-dione or N-tosylindole-4,7-dione with trifluoroacetamidocinnamaldehyde dimethylhydrazone, and subsequent cyclisation in alkaline conditions.

Novel β‐carboline‐based indole‐4,7‐quinone derivatives as NAD(P)H: Quinone‐oxidoreductase‐1 inhibitor with potent antitumor activities by inducing reactive oxygen species, apoptosis, and DNA damage
Eighteen new β‐carboline‐based indole‐4,7‐quinone derivatives (12a–i and 13a–i ) were designed and synthesized, and their in vitro and in vivo antiproliferativeactivities were studied. Most of target compounds showed strong inhibition on three human tumor cells' proliferation. In particular, the most active compound 13g not only displayed more prominent antiproliferativeactivities than β‐lapachone, a clinical
