Biomimeticsynthesis of 12-epi-ent-pentacyclindole 7, using as key step the cyclization of 12-epi-ent-polyalthenol acetate has been carried out. This way, the structure and absolute configuration of the natural product pentacyclindole 1 has been confirmed. The synthesized indole sesquiterpenes 7, 11 and 12 show cellular proliferation inhibition of a number of human leukaemic and solid tumour cell lines
