Egg Release Pheromone, Coelomic Fluid,Platynereis dumerilii,l-Ovothiol A,l-Ovothiol A Disulfide

Sex pheromones, released with the coelomic fluid by malePlatynereis dumeriliiinitiate egg release in swarm- ing females. The egg release pheromone, isolated from the coelomic fluid of sexually mature males, was iden- tified asl-Ovothiol A, which was found in male marine invertebrates for the first time. Isolation was obtained by reversed-phase high-performance liquid chromato- graphy in the biologically inactive disulfide form.
