Abstract
A sponge of the genus Theonella collected off Perth, Australia, contai ned a cyclic octapeptide. perthamide B, which weakly inhibited the bin ding of [I-125]IL-1 beta to intact EL4.6.1 cells with an IC50 of 27.6 mu M. The inhibition of binding could however, not be separated from t he cytotoxic effects of perthamide B. The structure was elucidated by spectroscopic methods.
