O. Papendorf et al., Hierridin B and 2,4-dimethoxy-6-heptadecyl-phenol, secondary metabolites from the cyanobacterium Phormidium ectocarpi with antiplasmodial activity, PHYTOCHEM, 49(8), 1998, pp. 2383-2386
Bioassay guided fractionation of the lipophilic extract of the marine cyano
bacterium Phormidium ectocarpi yielded a new natural product hierridin B an
d 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 towa
rds Plasmodium falciparum. (C) 1998 Published by Elsevier Science Ltd. All
