title: Ceratodictyols, 1-glyceryl ethers from the red alga-sponge association Ceratodictyon spongiosum/Haliclona cymaeformis.
abstract: Six 1-glyceryl ethers (1-6) were isolated from the red alga-sponge assemblage Ceratodictyon spongiosum/Haliclona cymaeformis. Structural assignments were conducted by interpretation of spectroscopic data and the modified Mosher's method. Four allylic alcohols were obtained as a pair of epimeric mixtures (3/4 and 5/6). These glyceryl ethers exhibited weak cytotoxic activity against HeLa human cervical cancer cells.
