Naseseazine C, a new anti-plasmodial dimeric diketopiperazine from a marine sediment derived Streptomyces sp.

Abstract

A new dimeric diketopiperazine, naseseazine C, and the known naseseazines A and B were isolated from solid culture extracts of an Australian marine sediment derived Streptomyces species. Naseseazine C displayed a new C-6′/C-3 linkage between the two diketopiperazine subunits and showed moderate activity against the chloroquine-sensitive malaria parasite, Plasmodium falciparum (3D7 strain).
