Abstract:
Bioassay guided fractionation of the lipophilic extract of the marine cyanobacterium Phormidium ectocarpi yielded a new natural product hierridin B and the previously described compound 2,4-dimethoxy-6-heptadecyl-phenol. Both structures were secured by extensive spectroscopic analysis (1D and 2D NMR, MS, GC-MS, IR). The isolate (mixture) showed antiplasmodial activity towards Plasmodium falciparum.
