Nine suvanine analogs including suvanine phenethylammonium salt and two new compounds were isolated from the marine sponge Coscinoderma sp., collected from Chuuk State, Federated States of Micronesia. The structures of the new compounds were elucidated by 2D NMR and HRMS analyses. Suvanine and a new analog exhibited weak but selective cytotoxicity against colon (HCT-15), lung (NCI-H23), stomach (NUGC-3), and prostate (PC-3) cancer cell lines.
