Structure and Receptor Participation of Periplanone A, the Sex Pheromone of the American Cockroach

Abstract Periplanones A (24 μg) and B (15 μg), the sex pheromones of the American cockroach, were isolated from the materials derived from 11500 females. The structure of periplanone A was elucidated to be (1Z,5E,7S*,10R*)-10(14)-epoxy-1,4(15),5-germacratrien-9-one. Either pheromone was revealed to participate with the corresponding sex pheromone receptor.
