A new adenine-substituted bromotyrosine-derived metabolite designated as aphrocallistin (1) has been isolated from the deep-water Hexactinellida sponge Aphrocallistes beatrix. Its structure was elucidated on the basis of spectral data and confirmed through a convergent, modular total synthetic route that is amenable toward future analogue preparation. Aphrocallistin inhibits the growth of a panel of human tumor cell lines with IC50 values ranging from 7.5 to > 100 mu M and has been shown to induce G1 cell cycle arrest in the PANC-1 pancreatic carcinoma cell line. Aphrocallistin has been fully characterized in the NCI cancer cell line panel and has undergone in vitro ADME pharmacological profiling.
