A. Rudi et Y. Kashman, 3 NEW CYTOTOXIC METABOLITES FROM THE MARINE SPONGE PLAKORTIS-HALICHONDRIOIDES, Journal of natural products, 56(10), 1993, pp. 1827-1830
Three new cytotoxic compounds, one a cyclic-peroxide-containing acid (
5) and the two others alkylated dihydroxy alpha,beta-unsaturated C22 a
nd C21 acids (6 and 7), were isolated from the marine sponge Plakortis
balichondrioides, which was collected off the coast of Jamaica. The s
tructures were elucidated through mass and mainly 1D and 2D nmr spectr
al analysis. All three acids are cytotoxic against P-388 murine leukem
ia.
