Ethyl 4-[2-(6-methyl-3-pyridyloxy)butyloxy]benzoate (2) was prepared as a novel anti-juvenile hormone (anti-JH) agent. Compound 2 induced precocious metamorphosis in larvae of the silkworm and black pigmentation of the larval cuticle, which are clearly recognized as JH-deficiency symptoms. The 4-ethoxycarbonyl group on the benzene ring was indispensable for activity. The activity of compound 2 could be fully counteracted by methoprene, a JH agonist, but not by the dietary administration of 20-hydroxyecdysone.
