Fascaplysin is a marine alkaloid based on 12H-pyrido[1–2-a:3,4-b′]diindole ring system.^[2] It was first isolated as a red pigment from the marine sponge Fascaplysinopsis reticulata that was collected in the South Pacific near Fiji in 1988.^[3] Fascaplysin possesses a broad range of in vitro biological activities including analgesic,^[4] antimicrobial, antifungal, antiviral, antimalarial, anti-angiogenic, and antiproliferative activity against numerous cancer cell lines.^[2]

Synthesis

The first total synthesis of fascaplysin was performed in seven steps from indole in 1990.^[5] Fascaplysin and its derivatives can be synthesized from tryptamine,^[6]^[7]^[8]^[9] beta-carboline,^[10] indoleketones,^[11]^[12] and indigo.^[13]
