“…Biofouling organisms such as blue mussels, barnacles and macroalgae cause serious problems by settling on ships’ hulls, cooling systems of power plants and aquaculture nets 1,2 . Organotin compounds such as TBTO [bis‐(tri‐ n ‐butyltin)‐oxide] have been used as effective chemicals to prevent biofouling, but their use has been restricted recently because these compounds are toxic to many marine organisms 3 . The use of organotin compounds as antifoulants has been prohibited in Japan and the leaching rate of TBTO from paint has been limited in the United States, Canada, Australia, and New Zealand 4 .…”

Fouling organisms cause serious problems by settling on ships’ hulls, and other marine infrastructures. Organotin compounds have been developed as effective antifoulants. However, environmental problems are associated with these compounds. It is necessary to find antifouling substances that exhibit a lower toxicity than those substances currently used. A new pyrimidine derivative, 3,4,5,6‐tetrahydro‐6‐hydroxymethyl‐3,6‐dimethyl‐4‐pyrimidinecarboxylic acid, (compound 1) and zooanemonin (compound 2) were isolated from the marine sponge Protophlitaspongia aga as antifouling substances against the barnacle Balanus amphitrite. We also found that α‐nicotinamide ribose (compound 3) inhibited germination and the attachment of Ulva spores.
