A new dipyrroloquinone, zyzzyanone A 1, having a pyrrolo[3,2 f]indole-4,8(1H,7H)-dione skeleton, was isolated from the Australian marine sponge Zyzzya fuliginosa, along with the known pyrroloquinoline alkaloids, makaluvamines C, E, G, H, and L, and damirones A and B. The structure of 1 was determined by spectroscopic data. Zyzzyanone A 1 shows moderate cytotoxic activity against mouse Ehrlich carcinoma cells (IC50 25 mug/mL), inhibits the cell division of fertilized sea urchin eggs at a concentration of 25 mug/mL, and exhibits UV-A and UV-B absorbing activity.
