Abstract

Three new cytotoxic glycolipids, erylusamine TA (8), erylusine (9) and erylusidine (10) have been isolated from a Red Sea sponge tentatively identified as Erylus cf. lendenfeldi. The structure of the three compounds was determined by interpretation of 2D NMR and FABMS data as trisaccharides of long-chain oxodihydroxyfatty acid amides formed with N,N-dimethyl-1,5- pentanediamine to yield 8 with ω-N,N-dimethylaminobutyl-N-methyl-1,3 - propanediamine to yield 9 and with 4-(aminobutyl) guanidine to yield 10 (R₃=COCH₂CH(CH₃)₂).
