Janoxepin is a novel oxepin derivative with a rare d-leucine incorporated. Brevicompanine B has previously only been isolated from Penicillium brevicompactum. Both compounds were tested in antimicrobial assays and found to be active against the malaria parasite Plasmodium falciparum 3D7 (IC.sub.50-values of 28 and 35mg/ml, respectively). However, no activity was observed in antifungal or antibacterial assays.
